The first rotation transmission wheel 15A and the second rotation transmission wheel 15B rotate with the rotation of the tire 21, whereby the rotation of the tire 21 is transmitted to the crawler 11 and the crawler 11 is driven.
 フレーム12は、各々がクローラ装置10に正対して右側(進行方向の左側)の第1フレーム12A、及び正対して左側(進行方向の右側)の第2フレーム12Bによって構成される。以下、第1フレーム12Aについて説明し、第2フレーム12Bは第1フレーム12Aと対称に現れるので、その説明を省略する。 The frame 12 includes a first frame 12A on the right side (left side in the traveling direction) facing the crawler device 10 and a second frame 12B on the left side (right side in the traveling direction) facing each other. Hereinafter, the first frame 12A will be described, and since the second frame 12B appears symmetrically with the first frame 12A, the description thereof is omitted.
 第1フレーム12Aは、第1プレート121A、第2プレート122A、中間プレート123A、回転伝達輪保持プレート124A、125A及び連結部保持プレート126Aによって構成される。第1プレート121Aは転動輪14A、14B、14Cを支持し、第2フレーム12Bは転動輪14F、14G、14Hを支持する。中間プレート12Cは転動輪14C、14D、14E、14Fを支持する。回転伝達輪保持プレート124Aは転動輪14B、14C及び第1回転伝達輪15Aを支持し、回転伝達輪保持プレート125Aは転動輪14F、14G及び第2回転伝達輪15Bを支持する。連結部保持プレート126Aは、第1回転伝達輪15A及び第2回転伝達輪15Bを支持し、各回転伝達輪の軸に支持された連結部19を支持する。 The first frame 12A includes a first plate 121A, a second plate 122A, an intermediate plate 123A, rotation transmission wheel holding plates 124A and 125A, and a connecting portion holding plate 126A. The first plate 121A supports the rolling wheels 14A, 14B, and 14C, and the second frame 12B supports the rolling wheels 14F, 14G, and 14H. The intermediate plate 12C supports the rolling wheels 14C, 14D, 14E, and 14F. The rotation transmission wheel holding plate 124A supports the rolling wheels 14B and 14C and the first rotation transmission wheel 15A, and the rotation transmission wheel holding plate 125A supports the rolling wheels 14F and 14G and the second rotation transmission wheel 15B. The connection portion holding plate 126A supports the first rotation transmission wheel 15A and the second rotation transmission wheel 15B, and supports the connection portion 19 supported by the shaft of each rotation transmission wheel.
 各プレート121Aから125Aには、各輪の軸が挿入される穴が設けられる。この軸が挿入される穴には、図示を省略した軸受が設けられ、軸が容易に回転できるよう構成される。なお、軸が挿入される穴が長穴である場合、軸受は軸と共に長穴内を移動可能に取り付けられる。 Each plate 121A to 125A is provided with a hole into which the shaft of each wheel is inserted. In the hole into which the shaft is inserted, a bearing (not shown) is provided so that the shaft can be easily rotated. When the hole into which the shaft is inserted is a long hole, the bearing is attached so as to be movable in the long hole together with the shaft.
 第1プレート121Aは、転動輪14Aの軸が挿入される長穴、転動輪14Bの軸が挿入される長穴、及び転動輪14Cの軸が挿入される長穴を有する。 The first plate 121A has a long hole into which the shaft of the rolling wheel 14A is inserted, a long hole into which the shaft of the rolling wheel 14B is inserted, and a long hole into which the shaft of the rolling wheel 14C is inserted.
 中間プレート123Aは、転動輪14C、14D、14E、14Fを支持し、各転動輪の軸が挿入される穴を有する。第1プレート121Aと中間プレート123Aとは、転動輪14Cを支持することによって、転動輪14Cの軸を中心として回動可能に連結される。 The intermediate plate 123A supports the rolling wheels 14C, 14D, 14E, and 14F and has a hole into which the shaft of each rolling wheel is inserted. The first plate 121A and the intermediate plate 123A are coupled so as to be rotatable about the axis of the rolling wheel 14C by supporting the rolling wheel 14C.
 回転伝達輪保持プレート124Aの下部には、転動輪14Bの軸が挿入される穴と、転動輪14Cの軸が挿入される穴とが設けられる。転動輪14Bの軸及び転動輪14Cの軸が第1プレート121A及び回転伝達輪保持プレート124Aに挿入されることによって、第1プレート121Aと回転伝達輪保持プレート124Aとが連結される。 The lower part of the rotation transmission wheel holding plate 124A is provided with a hole into which the shaft of the rolling wheel 14B is inserted and a hole into which the shaft of the rolling wheel 14C is inserted. By inserting the shaft of the rolling wheel 14B and the shaft of the rolling wheel 14C into the first plate 121A and the rotation transmission wheel holding plate 124A, the first plate 121A and the rotation transmission wheel holding plate 124A are connected.
 回転伝達輪保持プレート124Aの上部には回転伝達輪15Aの軸が挿入される長穴が設けられ、この長穴は上方に凸となる円弧に形成される。このため、回転伝達輪15Aは、転動輪14Cの周に沿って移動可能であり、第1プレート121Aが中間プレート123Aに対して回動しても、回転伝達輪15Aと転動輪14Cとがクローラ11を確実に挟むことができる。 A long hole into which the shaft of the rotation transmission wheel 15A is inserted is provided in the upper part of the rotation transmission wheel holding plate 124A, and this long hole is formed in a circular arc protruding upward. Therefore, the rotation transmission wheel 15A is movable along the circumference of the rolling wheel 14C, and even if the first plate 121A rotates with respect to the intermediate plate 123A, the rotation transmission wheel 15A and the rolling wheel 14C are crawled. 11 can be pinched reliably.
 回転伝達輪15Aの軸は、連結部保持プレート126Aの上部前方に設けられた長穴に挿入される。また、回転伝達輪15Bの軸は、連結部保持プレート126Aの上部後方に設けられた長穴に挿入される。これらの長穴は、回転伝達輪15A、15Bの回転軸151A、151Bを車両の前後方向に移動可能にする回転伝達輪移動可能部として機能する。回転伝達輪15Aの軸が連結部19の一端部に設けられた穴に挿入され、回転伝達輪15Bの軸が連結部19の他端部に設けられた穴に挿入され、連結部19が連結部保持プレート126Aの外側に取り付けられる。 The shaft of the rotation transmission wheel 15A is inserted into an elongated hole provided in front of the upper part of the connecting portion holding plate 126A. Further, the shaft of the rotation transmission wheel 15B is inserted into an elongated hole provided at the upper rear of the connecting portion holding plate 126A. These long holes function as a rotation transmission wheel movable portion that allows the rotation shafts 151A and 151B of the rotation transmission wheels 15A and 15B to move in the front-rear direction of the vehicle. The shaft of the rotation transmitting wheel 15A is inserted into a hole provided at one end of the connecting portion 19, the shaft of the rotation transmitting wheel 15B is inserted into a hole provided at the other end of the connecting portion 19, and the connecting portion 19 is connected. It is attached to the outside of the part holding plate 126A.
 第1回転伝達輪15Aの軸及び第2回転伝達輪15Bの軸が挿入される連結部保持プレート126Aの穴が長穴なので、第1回転伝達輪15A及び第2回転伝達輪15Bは前後に移動可能である。このため、二つの回転伝達輪15A、15Bの間隔をタイヤ21の径に合わせて可変でき、二つの回転伝達輪15A、15Bの間隔は連結部19が設定した長さに保持される。 Since the hole of the connecting portion holding plate 126A into which the shaft of the first rotation transmission wheel 15A and the shaft of the second rotation transmission wheel 15B are inserted is a long hole, the first rotation transmission wheel 15A and the second rotation transmission wheel 15B move back and forth. Is possible. For this reason, the interval between the two rotation transmission wheels 15A and 15B can be varied according to the diameter of the tire 21, and the interval between the two rotation transmission wheels 15A and 15B is maintained at the length set by the connecting portion 19.
 連結部保持プレート126Aの下部には、転動輪14Dの軸が挿入される穴と、転動輪14Eの軸が挿入される穴とが設けられる。転動輪14Dの軸及び転動輪14Eの軸が中間プレート123A及び連結部保持プレート126Aに挿入されることによって、中間プレート123Aと連結部保持プレート126Aとが連結される。 The lower part of the connecting portion holding plate 126A is provided with a hole into which the shaft of the rolling wheel 14D is inserted and a hole into which the shaft of the rolling wheel 14E is inserted. By inserting the shaft of the rolling wheel 14D and the shaft of the rolling wheel 14E into the intermediate plate 123A and the connecting portion holding plate 126A, the intermediate plate 123A and the connecting portion holding plate 126A are connected.
 回転伝達輪保持プレート125Aの下部には、転動輪14Fの軸が挿入される穴と、転動輪14Gの軸が挿入される穴とが設けられる。 The lower part of the rotation transmission wheel holding plate 125A is provided with a hole into which the shaft of the rolling wheel 14F is inserted and a hole into which the shaft of the rolling wheel 14G is inserted.
 回転伝達輪保持プレート125Aの上部には回転伝達輪15Bの軸が挿入される長穴が設けられ、この長穴は上方に凸となる円弧に形成される。このため、回転伝達輪15Bは、転動輪14Fの周に沿って移動可能であり、第2プレート122Aが中間プレート123Aに対して回動しても、回転伝達輪15Bと転動輪14Fとがクローラ11を確実に挟むことができる。 A long hole into which the shaft of the rotation transmission wheel 15B is inserted is provided in the upper part of the rotation transmission wheel holding plate 125A, and this long hole is formed in an arc protruding upward. Therefore, the rotation transmission wheel 15B is movable along the circumference of the rolling wheel 14F, and even if the second plate 122A rotates with respect to the intermediate plate 123A, the rotation transmission wheel 15B and the rolling wheel 14F are crawled. 11 can be pinched reliably.
 第2プレート122Aは、転動輪14Fの軸が挿入される長穴、転動輪14Gの軸が挿入される長穴、及び転動輪14Hの軸が挿入される長穴を有する。転動輪14Fの軸及び転動輪14Gの軸が第2プレート122A及び回転伝達輪保持プレート125Aに挿入されることによって、第2プレート122Aと回転伝達輪保持プレート125Aとが連結される。 The second plate 122A has a long hole into which the shaft of the rolling wheel 14F is inserted, a long hole into which the shaft of the rolling wheel 14G is inserted, and a long hole into which the shaft of the rolling wheel 14H is inserted. The shaft of the rolling wheel 14F and the shaft of the rolling wheel 14G are inserted into the second plate 122A and the rotation transmission wheel holding plate 125A, so that the second plate 122A and the rotation transmission wheel holding plate 125A are connected.
 図9、図10に示すように、第1フレーム12Aは、内側から、中間プレート123A、第1プレート121A及び第2プレート122A、回転伝達輪保持プレート124A及び125A、連結部保持プレート126Aの順に組み合わされて構成される。同様に、第2フレーム12Bは、内側から、中間プレート123B、第1プレート121B及び第2プレート122B、回転伝達輪保持プレート124B及び125B、連結部保持プレート126Bの順に組み合わされて構成される。 As shown in FIGS. 9 and 10, the first frame 12A is assembled from the inside in the order of the intermediate plate 123A, the first plate 121A and the second plate 122A, the rotation transmission wheel holding plates 124A and 125A, and the connecting portion holding plate 126A. Configured. Similarly, the second frame 12B is configured by combining the intermediate plate 123B, the first plate 121B and the second plate 122B, the rotation transmission wheel holding plates 124B and 125B, and the connecting portion holding plate 126B in this order from the inside.
 前述したように、転動輪14A、14B、14Cの軸が挿入される第1プレート121Aの穴が前後に長い長穴であり、転動輪14F、14G、14Hの軸が挿入される第2プレート122Aの穴が前後に長い長穴なので、クローラ11の張りを微小に変化でき、走行中に生じるクローラ11の撓みに対応できる。 As described above, the holes in the first plate 121A into which the shafts of the rolling wheels 14A, 14B, and 14C are inserted are elongated holes in the front and rear, and the second plate 122A into which the shafts of the rolling wheels 14F, 14G, and 14H are inserted. Since this hole is a long hole that is long in the front-rear direction, the tension of the crawler 11 can be changed minutely, and it is possible to cope with the bending of the crawler 11 that occurs during traveling.
 また、前述したように、第1プレート121Aと中間プレート123Aとは、転動輪14Cの軸によって回動可能に連結されており、第2プレート122A及び中間プレート123Aは、転動輪14Fの軸によって回動可能に連結される。このため、図12に示すように、フレーム12が転動輪14Cの軸及び転動輪14Fの軸を支点として折れ曲がることができ、クローラ装置10が障害物を乗り越える際の接地面積の減少を抑制でき、悪路走破性を向上できる。 Further, as described above, the first plate 121A and the intermediate plate 123A are rotatably connected by the shaft of the rolling wheel 14C, and the second plate 122A and the intermediate plate 123A are rotated by the shaft of the rolling wheel 14F. It is linked movably. For this reason, as shown in FIG. 12, the frame 12 can be bent with the axis of the rolling wheel 14C and the axis of the rolling wheel 14F as a fulcrum, and the reduction of the contact area when the crawler device 10 gets over the obstacle can be suppressed. Improves rough road performance.
 また、転動輪14Fの軸が挿入される第2プレート122Aの穴は左右に長い長穴となっており、第2プレート122Aは、中間プレート123Aに対して前後に可動する。同様に、転動輪14Cの軸が挿入される第1プレート121Aの穴は左右に長い長穴となっており、第1プレート121Aは、中間プレート123Aに対して前後に可動する。このため、フレーム12の全長が微小に変化できるので、走行中に生じるクローラ11の撓みに対応できる。 Also, the hole of the second plate 122A into which the shaft of the rolling wheel 14F is inserted is a long hole on the left and right, and the second plate 122A is movable back and forth with respect to the intermediate plate 123A. Similarly, the hole of the first plate 121A into which the shaft of the rolling wheel 14C is inserted is a long hole on the left and right, and the first plate 121A is movable back and forth with respect to the intermediate plate 123A. For this reason, since the full length of the frame 12 can be changed minutely, it is possible to cope with the bending of the crawler 11 that occurs during traveling.
 連結部保持プレート126Aには、移動規制部保持プレート127が上方に突出するように取り付けられる。移動規制部保持プレート127はT字形に形成されており、その下端部には上下に長い長穴が形成される。この長穴には軸128が挿入される。軸128は、連結部保持プレート126Aの穴にも挿入され、これによって、移動規制部保持プレート127が、上下に移動可能に連結部保持プレート126Aに取り付けられる。 The movement restricting portion holding plate 127 is attached to the connecting portion holding plate 126A so as to protrude upward. The movement restricting portion holding plate 127 is formed in a T shape, and a long hole is formed vertically at the lower end portion thereof. A shaft 128 is inserted into the elongated hole. The shaft 128 is also inserted into the hole of the connecting portion holding plate 126A, whereby the movement restricting portion holding plate 127 is attached to the connecting portion holding plate 126A so as to be movable up and down.
 移動規制部保持プレート127の上部の左端部及び右端部には、それぞれ第1回転伝達輪連結部320及び第2回転伝達輪連結部330が取り付けられる。そして、移動規制部保持プレート127は、回転伝達輪15A、15Bの間隔の変化に伴い、上下に移動する。 1st rotation transmission wheel connection part 320 and 2nd rotation transmission wheel connection part 330 are attached to the left end part and right end part of the upper part of movement control part holding plate 127, respectively. And the movement control part holding | maintenance plate 127 moves up and down with the change of the space | interval of rotation transmission wheel 15A, 15B.
 実施例1のクローラ11は、実施例2と同様に、センタークローラ111、センタークローラ111の両端部に位置する二つのサイドクローラ112A及び112Bによって構成される。なお、実施例1ではクローラ11の構成の説明を省略するが、実施例2のクローラ11と同様の構成(図16、図18など)を有する。 The crawler 11 according to the first embodiment includes a center crawler 111 and two side crawlers 112A and 112B located at both ends of the center crawler 111, as in the second embodiment. In the first embodiment, the description of the configuration of the crawler 11 is omitted.
 回転伝達輪15A、15Bは、クローラ11の上面に接する位置に設けられる。回転伝達輪15Aと転動輪14Cとでクローラ11を挟み、回転伝達輪15Bと転動輪14Fとでクローラ11を挟むので、回転伝達輪15A、15Bがクローラ11の上面に確実に接して、タイヤ21の回転が回転伝達輪15A、15Bを介してクローラ11に伝達される。また、回転伝達輪15A、15Bの凹凸と、クローラ11の凹凸(図示省略)が係合することによって、回転伝達輪15A、15Bの回転がクローラ11に確実に伝達される。 Rotation transmission wheels 15A and 15B are provided at positions in contact with the upper surface of the crawler 11. Since the crawler 11 is sandwiched between the rotation transmission wheel 15A and the rolling wheel 14C, and the crawler 11 is sandwiched between the rotation transmission wheel 15B and the rolling wheel 14F, the rotation transmission wheels 15A and 15B are surely in contact with the upper surface of the crawler 11 and the tire 21 Is transmitted to the crawler 11 via the rotation transmission wheels 15A and 15B. The rotation of the rotation transmission wheels 15 </ b> A and 15 </ b> B and the projections and depressions (not shown) of the crawler 11 are engaged, so that the rotation of the rotation transmission wheels 15 </ b> A and 15 </ b> B is reliably transmitted to the crawler 11.
 第1回転伝達輪15Aの回転軸151Aは、回転伝達輪保持プレート124A及び連結部保持プレート126Aを通過して、連結部19の一端部に保持される。第2回転伝達輪15Bの回転軸151Bは、回転伝達輪保持プレート125A及び連結部保持プレート126Aを通過して、連結部19の他端部に保持される。 The rotation shaft 151A of the first rotation transmission wheel 15A passes through the rotation transmission wheel holding plate 124A and the connection portion holding plate 126A and is held at one end of the connection portion 19. The rotation shaft 151B of the second rotation transmission wheel 15B passes through the rotation transmission wheel holding plate 125A and the connection portion holding plate 126A and is held at the other end of the connection portion 19.
 次に、実施例1のクローラ装置10を異なる径のタイヤに装着した状態を説明する。図2は、大径のタイヤに装着されたクローラ装置10を外側から見た側面図であり、図3は、小径のタイヤに装着されたクローラ装置10を外側から見た側面図である。 Next, a state where the crawler device 10 of Example 1 is mounted on tires having different diameters will be described. FIG. 2 is a side view of the crawler device 10 mounted on a large-diameter tire as viewed from the outside, and FIG. 3 is a side view of the crawler device 10 mounted on a small-diameter tire as viewed from the outside.
 図5に示すように、第1回転伝達輪15Aの回転軸151A及び第2回転伝達輪15Bの回転軸151Bは、長さが調整可能な棒状の連結部19によって連結される。連結部19は、長さが調節可能である。例えば、連結部19は、二つの筒状部材によって構成され、一方の筒状部材の外周に雄ねじが形成され、他方の筒状部材の内周に雌ねじが形成され、一方の部材を回すことによって長さが調整できる構造を採用可能である。また、内側の筒状部材にタイヤ21の径に対応する目盛を設けることによって、連結部19の外側の筒状部材の端部をタイヤ21の径に対応した目盛の位置に設定して、連結部19をタイヤ21の径に適する長さに調整できる。 As shown in Fig. 5, the rotation shaft 151A of the first rotation transmission wheel 15A and the rotation shaft 151B of the second rotation transmission wheel 15B are connected by a rod-like connection portion 19 whose length can be adjusted. The length of the connecting portion 19 can be adjusted. For example, the connecting portion 19 is constituted by two cylindrical members, a male screw is formed on the outer periphery of one cylindrical member, a female screw is formed on the inner periphery of the other cylindrical member, and the one member is rotated. It is possible to adopt a structure whose length can be adjusted. Further, by providing a scale corresponding to the diameter of the tire 21 on the inner cylindrical member, the end of the cylindrical member on the outer side of the connecting portion 19 is set at the position of the scale corresponding to the diameter of the tire 21 and connected. The part 19 can be adjusted to a length suitable for the diameter of the tire 21.
 第1回転伝達輪15Aの回転軸151Aと第2回転伝達輪15Bの回転軸151Bとの間隔が連結部19によって一定に保たれる。このため、車両20の走行時に回転伝達輪15A、15Bの間隔が安定し、回転伝達輪15A、15Bとタイヤ21とが安定に接触できる。 The distance between the rotation shaft 151A of the first rotation transmission wheel 15A and the rotation shaft 151B of the second rotation transmission wheel 15B is kept constant by the connecting portion 19. For this reason, when the vehicle 20 is traveling, the interval between the rotation transmission wheels 15A and 15B is stabilized, and the rotation transmission wheels 15A and 15B and the tire 21 can stably contact each other.
 具体的には、クローラ装置10が大径のタイヤに装着される場合、図2に示すように、連結部19を伸長して、第1回転伝達輪15Aと第2回転伝達輪15Bとの間隔を長くする。一方、クローラ装置10が小径のタイヤに装着される場合、図3に示すように、連結部19を短縮して、第1回転伝達輪15Aと第2回転伝達輪15Bとの間隔を短くする。 Specifically, when the crawler device 10 is mounted on a large-diameter tire, as shown in FIG. 2, the connecting portion 19 is extended so that the distance between the first rotation transmission wheel 15A and the second rotation transmission wheel 15B is increased. Lengthen. On the other hand, when the crawler device 10 is attached to a small-diameter tire, as shown in FIG. 3, the connecting portion 19 is shortened to shorten the interval between the first rotation transmission wheel 15A and the second rotation transmission wheel 15B.
 第1回転伝達輪連結部320の上端部は移動規制部保持プレート127に連結され、下端部は連結部19に連結される。第2回転伝達輪連結部330の上端部は移動規制部保持プレート127に連結され、下端部は連結部19に連結される。このため、連結部19の長さを変えることによって、第1回転伝達輪連結部320及び第2回転伝達輪連結部330の角度を変えることができる。 The upper end portion of the first rotation transmission wheel connecting portion 320 is connected to the movement restricting portion holding plate 127 and the lower end portion is connected to the connecting portion 19. The upper end portion of the second rotation transmission wheel connecting portion 330 is connected to the movement restricting portion holding plate 127 and the lower end portion is connected to the connecting portion 19. For this reason, the angle of the 1st rotation transmission wheel connection part 320 and the 2nd rotation transmission wheel connection part 330 can be changed by changing the length of the connection part 19. FIG.
 また、側面ローラ313Aが取り付けられる軸311A及び側面ローラ313Bが取り付けられる軸311Bの長さを変えることによって、上面ローラ314A、314Bをタイヤ21の上面と接触する位置に配置する。これによって、タイヤ21を確実に回転伝達輪15A、15Bに接触させ、クローラ装置10のタイヤ21からの離脱を防止できる。 Further, by changing the lengths of the shaft 311A to which the side roller 313A is attached and the shaft 311B to which the side roller 313B is attached, the upper surface rollers 314A and 314B are arranged at positions where they contact the upper surface of the tire 21. Accordingly, the tire 21 can be reliably brought into contact with the rotation transmission wheels 15A and 15B, and the crawler device 10 can be prevented from being detached from the tire 21.
 連結部19をタイヤ21の直径に合わせた長さに調整することによって、回転伝達輪15A、15Bがタイヤ21の直径に合わせた位置に移動するので、連結部19の長さを調整するだけで、様々な径のタイヤ21にクローラ装置10を装着できる。 By adjusting the connecting portion 19 to a length that matches the diameter of the tire 21, the rotation transmission wheels 15 </ b> A and 15 </ b> B move to a position that matches the diameter of the tire 21, so only the length of the connecting portion 19 is adjusted. The crawler device 10 can be mounted on the tires 21 having various diameters.
 次に、転動輪14A~14Hについて説明する。 Next, the rolling wheels 14A to 14H will be described.
 転動輪は、前方から転動輪14A、14B、14C、14D、14E、14F、14G、14Hの順にフレームに軸支されており、前述したように、転動輪14Aと転動輪14Hとの間にクローラ11が巻き掛けされる。各転動輪は、2又は3枚の車輪によって構成される。また、横から見て、隣接する転動輪が重なるように配置される場合、隣接する転動輪は互いに干渉しないように軸方向でズレた位置に配置される。例えば、軸方向において、3枚の転動輪14Aの間の位置に、2枚の転動輪14Bが配置される。 The rolling wheels are pivotally supported on the frame in the order of the rolling wheels 14A, 14B, 14C, 14D, 14E, 14F, 14G, and 14H from the front, and as described above, the crawler is between the rolling wheels 14A and the rolling wheels 14H. 11 is wound. Each rolling wheel is constituted by two or three wheels. Further, when the adjacent rolling wheels are arranged so as to overlap each other when viewed from the side, the adjacent rolling wheels are arranged at positions shifted in the axial direction so as not to interfere with each other. For example, the two rolling wheels 14B are arranged at a position between the three rolling wheels 14A in the axial direction.
 転動輪14Aの中間の車輪及び転動輪14Hの中間の車輪にはクローラ11の内側の凸応と係合する凹凸が設けられる。 The middle wheel of the rolling wheel 14A and the middle wheel of the rolling wheel 14H are provided with unevenness that engages with the convexity inside the crawler 11.
 クローラ装置10が地面から受ける力は転動輪14A~14Hが受け、フレーム12が転動輪14A~14Hを支え、回転伝達輪15A、15Bを介して、車両20に伝達される。 The force that the crawler device 10 receives from the ground is received by the rolling wheels 14A to 14H, and the frame 12 supports the rolling wheels 14A to 14H and is transmitted to the vehicle 20 via the rotation transmitting wheels 15A and 15B.
 次に、図2、図3、図4を参照して、タイヤ移動規制部16の構成を説明する。 Next, the configuration of the tire movement restriction unit 16 will be described with reference to FIGS. 2, 3, and 4.

And an axis 312A extending inward of the vehicle 20 in parallel with the rotation axis of the tire 21. A side roller 313A that contacts the outer side surface of the tire 21 is rotatably attached to the shaft 311A. An upper surface roller 314A that contacts the upper surface of the tire 21 is rotatably attached to the shaft 312A.
 同様に、上方連結部310Bは、L字状に形成されており、中心部300から車両20の外側でタイヤ21の側面に沿って後方上方(図5において、右上方)に延伸する軸311Bと、軸311Bの上端部からタイヤ21の回転軸と並行に車両20の内側に向かって延伸する軸312Bとを有する。軸311Bには、タイヤ21の外側の側面に接触する側面ローラ313Bが回転可能に取り付けられる。また、軸312Bにはタイヤ21の上側の面に接触する上面ローラ314Bが回転可能に取り付けられる。 Similarly, the upper connecting portion 310B is formed in an L shape, and has a shaft 311B extending from the center portion 300 to the rear upper side (upper right in FIG. 5) along the side surface of the tire 21 outside the vehicle 20. The shaft 311B extends from the upper end of the shaft 311B toward the inside of the vehicle 20 in parallel with the rotation axis of the tire 21. A side roller 313B that contacts the outer side surface of the tire 21 is rotatably attached to the shaft 311B.

 なお、実施例1のクローラ装置10は、二つの上方連結部310A、310Bを有するが、後述する実施例2と同様に、一つの上方連結部310を有してもよい。 In addition, although the crawler apparatus 10 of Example 1 has two upper connection parts 310A and 310B, it may have one upper connection part 310 similarly to Example 2 mentioned later.
 第1回転伝達輪連結部320は、車両20の外側でタイヤ21の側面に沿って中心部300から第1回転伝達輪15A側に向かって延設され、第1回転伝達輪15A側の下端部は第1回転伝達輪15Aの回転軸151Aに連結される。具体的には、第1回転伝達輪連結部320の第1回転伝達輪15A側の端部に形成される穴に第1回転伝達輪15Aの回転軸151Aが挿入され、第1回転伝達輪連結部320が回転伝達輪15Aを軸支するように連結される。また、第1回転伝達輪連結部320には、タイヤ21の外側の側面に接触する側面ローラ321が回転可能に取り付けられる。 The first rotation transmission wheel connecting portion 320 is extended from the center portion 300 toward the first rotation transmission wheel 15A side along the side surface of the tire 21 outside the vehicle 20, and a lower end portion on the first rotation transmission wheel 15A side. Is connected to the rotation shaft 151A of the first rotation transmission wheel 15A. Specifically, the rotation shaft 151A of the first rotation transmission wheel 15A is inserted into a hole formed in the end portion on the first rotation transmission wheel 15A side of the first rotation transmission wheel connection portion 320, and the first rotation transmission wheel connection portion is connected. The part 320 is connected so as to pivotally support the rotation transmission wheel 15A. Further, a side roller 321 that contacts the outer side surface of the tire 21 is rotatably attached to the first rotation transmission wheel connecting portion 320.
 第1回転伝達輪連結部320は、タイヤ21の外側の側面に接触する側面ローラ321が回転可能に取り付けられる軸と、前記軸の下側に設けられ第1回転伝達輪15Aの回転軸151Aが挿入される穴を有する下板状部とを有する。第1回転伝達輪連結部320の上部には中心部300において第2回転伝達輪連結部330と連結される上板状部が取り付けられ、第1回転伝達輪連結部320の上端部と上板状部の下端部とは移動規制部保持プレート127の上部に取り付けられる。 The first rotation transmission wheel connecting portion 320 includes a shaft on which a side roller 321 that contacts the outer side surface of the tire 21 is rotatably mounted, and a rotation shaft 151A of the first rotation transmission wheel 15A provided below the shaft. And a lower plate-like portion having a hole to be inserted. An upper plate-like portion connected to the second rotation transmission wheel connecting portion 330 at the central portion 300 is attached to the upper portion of the first rotation transmission wheel connecting portion 320, and an upper end portion and an upper plate of the first rotation transmission wheel connecting portion 320 are attached. The lower end portion of the shape portion is attached to the upper portion of the movement restricting portion holding plate 127.
 第2回転伝達輪連結部330は、車両20の外側でタイヤ21の側面に沿って中心部300から第2回転伝達輪15B側に向かって延設され、第2回転伝達輪15B側の下端部は第2回転伝達輪15Bの回転軸151Bに連結される。具体的には、第2回転伝達輪連結部330の第2回転伝達輪15B側の端部に形成される穴に第2回転伝達輪15Bの回転軸151Bが挿入され、第2回転伝達輪連結部330が回転伝達輪15Bを軸支するように連結される。また、第2回転伝達輪連結部330には、タイヤ21の外側の側面に接触する側面ローラ331が回転可能に取り付けられる。 The second rotation transmission wheel coupling portion 330 is extended from the center 300 toward the second rotation transmission wheel 15B side along the side surface of the tire 21 outside the vehicle 20, and a lower end portion on the second rotation transmission wheel 15B side. Is connected to the rotation shaft 151B of the second rotation transmission wheel 15B. Specifically, the rotation shaft 151B of the second rotation transmission wheel 15B is inserted into a hole formed in the end portion of the second rotation transmission wheel connection portion 330 on the second rotation transmission wheel 15B side, and the second rotation transmission wheel connection portion 330 is connected. The part 330 is connected so as to pivotally support the rotation transmission wheel 15B. Further, a side roller 331 that contacts the outer side surface of the tire 21 is rotatably attached to the second rotation transmission wheel connecting portion 330.
 第2回転伝達輪連結部330は、タイヤ21の外側の側面に接触する側面ローラ331が回転可能に取り付けられる軸と、前記軸の下側に設けられ第2回転伝達輪15Bの回転軸151Bが挿入される穴を有する下板状部とを有する。第2回転伝達輪連結部330の上部には中心部300において第2回転伝達輪連結部330と連結される上板状部が取り付けられ、第2回転伝達輪連結部330の上端部と上板状部の下端部との移動規制部保持プレート127の上部に取り付けられる。 The second rotation transmission wheel connecting portion 330 includes a shaft on which a side roller 331 that contacts the outer side surface of the tire 21 is rotatably mounted, and a rotation shaft 151B of the second rotation transmission wheel 15B provided below the shaft. And a lower plate-like portion having a hole to be inserted. An upper plate-like portion connected to the second rotation transmission wheel connecting portion 330 at the center portion 300 is attached to the upper portion of the second rotation transmission wheel connecting portion 330, and an upper end portion and an upper plate of the second rotation transmission wheel connecting portion 330 are attached. It attaches to the upper part of the movement control part holding | maintenance plate 127 with the lower end part of a shape part.
 上面ローラ314A及び314Bがタイヤ21の上側の面に上方から接触することによって、タイヤ21の上方向の移動を規制する。また、上面ローラ314A、314B及び回転伝達輪15A、15Bが4方向からタイヤ21に接触することによって、タイヤ21の横方向の移動を規制する。このため、タイヤ移動規制部16のタイヤ21に対する位置ずれを防止できる。 The upper rollers 314A and 314B come into contact with the upper surface of the tire 21 from above, thereby restricting the upward movement of the tire 21. Further, when the upper surface rollers 314A and 314B and the rotation transmission wheels 15A and 15B come into contact with the tire 21 from four directions, the lateral movement of the tire 21 is restricted. For this reason, the position shift with respect to the tire 21 of the tire movement control part 16 can be prevented.
 以上によって、外側規制部30は、第1回転伝達輪連結部320によって回転軸151A及び連結部保持プレート126Aに連結され、第2回転伝達輪連結部330によって回転軸151B及び連結部保持プレート126Aに連結され、上方連結部310Aの上面ローラ314A及び上方連結部310Bの上面ローラ314Bがタイヤ21に上方から接触するので、外側規制部30が、タイヤ21の上方向及び前後方向への移動を規制する。このため、タイヤ移動規制部16のタイヤ21に対する位置ずれを防止でき、タイヤ21が第1回転伝達輪15A及び第2回転伝達輪15Bから外れることを防止できる。 As described above, the outer restricting portion 30 is connected to the rotating shaft 151A and the connecting portion holding plate 126A by the first rotation transmission wheel connecting portion 320, and is connected to the rotating shaft 151B and the connecting portion holding plate 126A by the second rotation transmitting wheel connecting portion 330. Since the upper surface roller 314A of the upper connection portion 310A and the upper surface roller 314B of the upper connection portion 310B are in contact with the tire 21 from above, the outer restriction portion 30 restricts movement of the tire 21 in the upward direction and the front-rear direction. . For this reason, it is possible to prevent displacement of the tire movement restricting portion 16 with respect to the tire 21 and to prevent the tire 21 from being detached from the first rotation transmission wheel 15A and the second rotation transmission wheel 15B.
 なお、上方連結部310Aの軸311A、及び上方連結部310Bの軸311Bは、長手方向の長さが調整可能である。例えば、軸311A、311B、は、二つの棒形状の部材によって構成され、二つの棒形状の部材の一方に雄ねじが形成され、他方に雌ねじが形成され、一方の部材を回すことによって、長さが調整される構造を採用可能である。側面ローラ313A、313Bがタイヤ21の上側の面に接触するように、上方連結部310A、310Bの長さを調整するとよい。 Note that the length in the longitudinal direction of the shaft 311A of the upper connecting portion 310A and the shaft 311B of the upper connecting portion 310B can be adjusted. For example, the shafts 311A and 311B are constituted by two rod-shaped members, one of the two rod-shaped members is formed with a male screw and the other is formed with a female screw. It is possible to adopt a structure in which is adjusted. The lengths of the upper coupling portions 310A and 310B may be adjusted so that the side rollers 313A and 313B come into contact with the upper surface of the tire 21.
 また、第1回転伝達輪連結部320及び第2回転伝達輪連結部330は、クローラ装置10が装着されるタイヤ21のサイズを考慮した固定長(例えば、最小サイズのタイヤに装着した場合、中心部300がタイヤ21の中心に等しい位置となる)であるが、その長さは調整可能でもよい。 In addition, the first rotation transmission wheel coupling portion 320 and the second rotation transmission wheel coupling portion 330 are fixed lengths that take into account the size of the tire 21 to which the crawler device 10 is mounted (for example, the center is the center when the tire is mounted on a minimum size tire). The length of the portion 300 is equal to the center of the tire 21), but the length may be adjustable.
 図4に示すように、内側規制部40は、第1回転伝達輪連結部410及び第2回転伝達輪連結部420を有し、第1回転伝達輪連結部410及び第2回転伝達輪連結部420は、略L字形に形成される。 As shown in FIG. 4, the inner regulating part 40 includes a first rotation transmission wheel connection part 410 and a second rotation transmission wheel connection part 420, and the first rotation transmission wheel connection part 410 and the second rotation transmission wheel connection part 420. 420 is substantially L-shaped.
 第1回転伝達輪連結部410は、タイヤ21の内側の側面に接触する側面ローラ413が回転可能に取り付けられる軸411と、当該軸の下側に設けられ第1回転伝達輪15Aの回転軸151Aが挿入される穴を有する下板状部と、当該軸の上側に設けられホイールローラ414の軸が取り付けられる上板状部と、ホイールローラ414の軸とを有する。 The first rotation transmission wheel connecting portion 410 includes a shaft 411 on which a side roller 413 that contacts the inner side surface of the tire 21 is rotatably mounted, and a rotation shaft 151A of the first rotation transmission wheel 15A provided below the shaft. A lower plate-like portion having a hole into which the wheel roller 414 is inserted, an upper plate-like portion provided on the upper side of the shaft to which the shaft of the wheel roller 414 is attached, and a shaft of the wheel roller 414.
 第1回転伝達輪連結部410の下部に設けられた穴に回転軸151Aが挿入されることによって、第1回転伝達輪連結部410が回転伝達輪15Aを軸支するように連結される。 When the rotation shaft 151A is inserted into a hole provided in the lower portion of the first rotation transmission wheel coupling portion 410, the first rotation transmission wheel coupling portion 410 is coupled so as to pivotally support the rotation transmission wheel 15A.
 軸412には、ホイールの内周面に上方から接触するホイールローラ414が回転可能に取り付けられる。 A wheel roller 414 that comes into contact with the inner peripheral surface of the wheel from above is rotatably attached to the shaft 412.
 第2回転伝達輪連結部420は、タイヤ21の内側の側面に接触する側面ローラ413が回転可能に取り付けられる軸421と、当該軸の下側に設けられ第1回転伝達輪15Aの回転軸151Aが挿入される穴を有する下板状部と、当該軸の上側に設けられホイールローラ424の軸が取り付けられる上板状部と、ホイールローラ424の軸とを有する。 The second rotation transmission wheel connecting portion 420 includes a shaft 421 on which a side roller 413 contacting the inner side surface of the tire 21 is rotatably mounted, and a rotation shaft 151A of the first rotation transmission wheel 15A provided below the shaft. A lower plate-like portion having a hole into which the wheel roller 424 is inserted, an upper plate-like portion provided on the upper side of the shaft to which the shaft of the wheel roller 424 is attached, and a shaft of the wheel roller 424.
 第1回転伝達輪連結部410の下部に設けられた穴に回転軸151Aが挿入されることによって、第1回転伝達輪連結部410が回転伝達輪15Aを軸支するように連結される。 When the rotation shaft 151A is inserted into a hole provided in the lower portion of the first rotation transmission wheel coupling portion 410, the first rotation transmission wheel coupling portion 410 is coupled so as to pivotally support the rotation transmission wheel 15A.
 軸422には、ホイールの内周面に上方から接触するホイールローラ424が回転可能に取り付けられる。 A wheel roller 424 that contacts the inner peripheral surface of the wheel from above is rotatably attached to the shaft 422.
 このように、内側規制部40は、連結部保持プレート126Aに取り付けられて、第1回転伝達輪連結部410のホイールローラ414及び第2回転伝達輪連結部420のホイールローラ424がホイールの内側の下面に上方から接触するので、内側規制部40が、タイヤ21の上方向への移動を規制する。このため、タイヤ移動規制部16のタイヤ21に対する位置ずれを防止でき、タイヤ21が第1回転伝達輪15A及び第2回転伝達輪15Bから外れることを防止できる。 As described above, the inner regulation portion 40 is attached to the coupling portion holding plate 126A, and the wheel roller 414 of the first rotation transmission wheel coupling portion 410 and the wheel roller 424 of the second rotation transmission wheel coupling portion 420 are disposed inside the wheel. Since the lower surface comes into contact with the upper surface, the inner regulation portion 40 regulates the upward movement of the tire 21. For this reason, it is possible to prevent displacement of the tire movement restricting portion 16 with respect to the tire 21 and to prevent the tire 21 from being detached from the first rotation transmission wheel 15A and the second rotation transmission wheel 15B.
 タイヤ21の側面が、側面ローラ321と側面ローラ413とによって挟まれ、側面ローラ331と側面ローラ423とによって挟まれるので、タイヤ21の左右方向のずれを規制できる。また、車両20のハンドルを操作して進行方向を変更する時に、タイヤ21の向きの変更に伴って、クローラ装置10の向きを変更できる。 Since the side surface of the tire 21 is sandwiched between the side roller 321 and the side roller 413 and sandwiched between the side roller 331 and the side roller 423, the lateral displacement of the tire 21 can be regulated. Further, when the traveling direction is changed by operating the handle of the vehicle 20, the direction of the crawler device 10 can be changed along with the change of the direction of the tire 21.
 第1回転伝達輪連結部410及び第2回転伝達輪連結部420は、クローラ装置10が装着されるタイヤ21のサイズを考慮した固定長(例えば、最小サイズのタイヤに装着した場合、中心部300がタイヤ21の中心に等しい位置となる)であるが、その長さを調整可能でもよい。 The first rotation transmission wheel coupling portion 410 and the second rotation transmission wheel coupling portion 420 are fixed lengths that take into account the size of the tire 21 to which the crawler device 10 is mounted (for example, the center portion 300 when mounted on a minimum size tire). Is equal to the center of the tire 21), but the length thereof may be adjustable.
 クローラ装置10の前後の上部には、クローラ11の上側を覆うようにスノーガード取付部18がフレーム12(第1プレート121A、121B、第2プレート122A、122B)に取り付けられる(図5参照)。スノーガード取付部18には、図13に示すように、スノーガード50が取り付けられる。スノーガード50は、その先端が地面近くに至るように、クローラ装置10の前方に延伸する。クローラ装置10を装着した車両20が走行する際に、スノーガード50が積雪の上部の柔らかい雪を除去することによって、クローラ装置10(車両20)が雪に埋まらず、雪上の走行性を向上できる。 The snow guard mounting portion 18 is mounted on the frame 12 ( first plate 121A, 121B, second plate 122A, 122B) so as to cover the upper side of the crawler 11 at the front and rear upper portions of the crawler device 10 (see FIG. 5). As shown in FIG. 13, a snow guard 50 is attached to the snow guard attaching portion 18. The snow guard 50 extends forward of the crawler device 10 so that the tip of the snow guard 50 reaches near the ground. When the vehicle 20 equipped with the crawler device 10 travels, the snow guard 50 removes soft snow on the top of the snow, so that the crawler device 10 (vehicle 20) is not buried in snow and the traveling performance on snow can be improved. .
 中間装置60は、図1に示すように、車両20の前輪と後輪との間の車体の下部に取り付けられ、クローラ61、フレーム62、アーム63及び転動輪64A~64Dを有する。 As shown in FIG. 1, the intermediate device 60 is attached to the lower part of the vehicle body between the front and rear wheels of the vehicle 20, and includes a crawler 61, a frame 62, an arm 63, and rolling wheels 64A to 64D.
 クローラ61は、転動輪64Aと転動輪64Dとの間に巻き掛けされており、車両20の走行に伴って駆動する。なお、中間装置60は、クローラ装置10と異なり、タイヤ21の回転によって駆動する駆動機構を有さず、クローラ61の地面との摩擦によって、車両20の走行に伴いクローラ61が駆動する。なお、中間装置60は、その用途を雪上走行に限定すれば、クローラ61ではなく、そりを装着してもよい The crawler 61 is wound between the rolling wheel 64A and the rolling wheel 64D and is driven as the vehicle 20 travels. Unlike the crawler device 10, the intermediate device 60 does not have a drive mechanism that is driven by the rotation of the tire 21, and the crawler 61 is driven as the vehicle 20 travels by friction with the ground of the crawler 61. The intermediate device 60 may be equipped with a sled instead of the crawler 61 if its use is limited to running on snow.
 フレーム62は、その上部にアーム63が取り付けられており、その下部で転動輪64A~64Dを軸支する。 The arm 62 is attached to the upper part of the frame 62, and the rolling wheels 64A to 64D are pivotally supported at the lower part thereof.
 アーム63は、上端部が車両20に取り付けられ、下端部がフレーム62に取り付けられる。アーム63は、長さを調整できるように構成されており、中間装置を車両に取り付けた後にアーム63の長さを調整して、中間装置60の下面とクローラ装置10の下面とが等しい高さになるようにする。また、アーム63は軸方向の付勢によって伸縮可能なバネ性を有してもよい。アーム63を伸縮可能に構成することによって、中間装置60が前後に傾くことができ、地面の凹凸に中間装置60が追従でき、悪路走破性を向上できる。 The arm 63 has an upper end attached to the vehicle 20 and a lower end attached to the frame 62. The arm 63 is configured to be adjustable in length, and after the intermediate device is attached to the vehicle, the length of the arm 63 is adjusted so that the lower surface of the intermediate device 60 and the lower surface of the crawler device 10 are equal in height. To be. The arm 63 may have a spring property that can be expanded and contracted by an axial bias. By configuring the arm 63 to be extendable and retractable, the intermediate device 60 can be tilted back and forth, the intermediate device 60 can follow the unevenness of the ground, and rough road running performance can be improved.
 フレーム62の前端部に転動輪64Aが回転可能に取り付けられ、後端部に転動輪64Dが回転可能に取り付けられる。転動輪64Aと転動輪64Dの間には、転動輪64B、64Cが回転可能にフレーム62に取り付けられる。転動輪64A~64Dは、クローラ61に地面から受ける力を受け、フレーム62が転動輪64A~64Dを支える。 The rolling wheel 64A is rotatably attached to the front end portion of the frame 62, and the rolling wheel 64D is rotatably attached to the rear end portion. Between the rolling wheels 64A and 64D, the rolling wheels 64B and 64C are rotatably attached to the frame 62. The rolling wheels 64A to 64D receive the force received from the ground by the crawler 61, and the frame 62 supports the rolling wheels 64A to 64D.
 中間装置60は、クローラ61を駆動する駆動機構を有さないが、接地面積の増加によって、軟弱な地面や雪上の走破性を向上できる。 The intermediate device 60 does not have a drive mechanism for driving the crawler 61, but can improve running performance on soft ground or snow by increasing the contact area.
 なお、図11に示すように、車両20には中間装置60が装着されなくてもよい。中間装置60を装着しない場合、接地面積は減少するが、軽量化できる。 As shown in FIG. 11, the intermediate device 60 may not be attached to the vehicle 20. When the intermediate device 60 is not attached, the ground contact area is reduced, but the weight can be reduced.
 次に、実施例1のクローラ装置10を車両20に装着する手順を説明する。図14、図15は、実施例1のクローラ装置を車両に装着する手順を示す図である。 Next, a procedure for mounting the crawler device 10 according to the first embodiment on the vehicle 20 will be described. 14 and 15 are diagrams illustrating a procedure for mounting the crawler device according to the first embodiment on a vehicle.
 まず、クローラ装置10を装着する車両20のタイヤ21の径に適合する長さに連結部19を設定し、クローラ装置10からタイヤ移動規制部16を取り外す。そして、クローラ装置10の後部にスロープを取り付ける。本実施例では、スノーガード50がスロープとして利用でき、クローラ装置10の後方のスノーガード取付部18にスノーガードを取り付ける。このとき、スノーガード50には脚51が取り付けられている。脚51は地面に接触して、スロープを上る車両20の重さを支える。 First, the connecting portion 19 is set to a length that matches the diameter of the tire 21 of the vehicle 20 on which the crawler device 10 is mounted, and the tire movement restricting portion 16 is removed from the crawler device 10. Then, a slope is attached to the rear part of the crawler device 10. In the present embodiment, the snow guard 50 can be used as a slope, and the snow guard is attached to the snow guard attaching portion 18 behind the crawler device 10. At this time, legs 51 are attached to the snow guard 50. The leg 51 contacts the ground and supports the weight of the vehicle 20 that goes up the slope.
 そして、クローラ装置10の後方から車両20を前進させ、前輪がスロープを上る。そして、図14に示すように、第1回転伝達輪15Aと第2回転伝達輪15Bとの間に前輪21が収まる位置で車両20を停止する。この状態で、タイヤ移動規制部16をセットし、クローラ装置10を前輪21に固定する。 Then, the vehicle 20 is advanced from the back of the crawler device 10, and the front wheel goes up the slope. Then, as shown in FIG. 14, the vehicle 20 is stopped at a position where the front wheel 21 is located between the first rotation transmission wheel 15A and the second rotation transmission wheel 15B. In this state, the tire movement restricting portion 16 is set and the crawler device 10 is fixed to the front wheel 21.
 一方、前部にスロープを取り付けたクローラ装置10を車両20の後方に置き、車両20を後退させ、後輪がスロープを上る(図15参照)。そして、第1回転伝達輪15Aと第2回転伝達輪15Bとの間に後輪21が収まる位置で車両20を停止する。この状態で、タイヤ移動規制部16をセットし、クローラ装置10を後輪21に固定する。 On the other hand, the crawler device 10 with the slope attached to the front is placed behind the vehicle 20, the vehicle 20 is moved backward, and the rear wheel goes up the slope (see FIG. 15). Then, the vehicle 20 is stopped at a position where the rear wheel 21 fits between the first rotation transmission wheel 15A and the second rotation transmission wheel 15B. In this state, the tire movement restricting portion 16 is set, and the crawler device 10 is fixed to the rear wheel 21.
 以上に説明したように、実施例1のクローラ装置10は、二つの回転伝達輪15A、15Bの軸の間隔を設定された長さを調節可能な棒状部材で構成される連結部19を有するので、様々な直径のタイヤに装着でき、装着時の調整を容易にすることができる。 As described above, the crawler device 10 according to the first embodiment includes the connecting portion 19 formed of a rod-shaped member capable of adjusting the length of the shaft between the two rotation transmission wheels 15A and 15B. It can be mounted on tires of various diameters, and adjustment during mounting can be facilitated.
 また、側面ローラ321が取り付けられる第1回転伝達輪連結部320の下端部を連結部19の一端と連結し、側面ローラ331が取り付けられる第2回転伝達輪連結部330の下端部を連結部19の他端と連結したので、クローラ装置10の横方向への移動を規制し、装着されるタイヤ21の径に応じて側面ローラ321、331がタイヤ21に接触する角度を変更することができる。 Further, the lower end portion of the first rotation transmission wheel connecting portion 320 to which the side roller 321 is attached is connected to one end of the connecting portion 19, and the lower end portion of the second rotation transmission wheel connecting portion 330 to which the side roller 331 is attached is connected to the connecting portion 19. Therefore, the crawler device 10 can be restricted from moving in the lateral direction, and the angle at which the side rollers 321 and 331 come into contact with the tire 21 can be changed according to the diameter of the tire 21 to be mounted.
 さらに、側面ローラ413が取り付けられる第1回転伝達輪連結部410の下端部を連結部19の一端と連結し、側面ローラ423が取り付けられる第2回転伝達輪連結部420の下端部を連結部19の他端と連結したので、クローラ装置10の横方向への移動を規制し、装着されるタイヤ21の径に応じて側面ローラ413、423がタイヤ21に接触する角度を変更することができる。 Further, the lower end portion of the first rotation transmission wheel connecting portion 410 to which the side roller 413 is attached is connected to one end of the connecting portion 19, and the lower end portion of the second rotation transmission wheel connecting portion 420 to which the side roller 423 is attached is connected to the connecting portion 19. Since the other end of the crawler device 10 is connected to the other end of the crawler device 10, the lateral movement of the crawler device 10 can be restricted, and the angle at which the side rollers 413 and 423 contact the tire 21 can be changed according to the diameter of the tire 21 to be mounted.
 また、タイヤ移動規制部16は、タイヤ21に上側から接する一つ又は複数の上面ローラ314、314A、314Bを有するので、クローラ装置10の上下方向への移動を規制でき、回転伝達輪15A、15Bが確実にタイヤ21に接触して、タイヤ21の回転をクローラ11に伝達できる。 Further, since the tire movement restricting portion 16 has one or a plurality of upper surface rollers 314, 314A, and 314B that are in contact with the tire 21 from above, it is possible to restrict the movement of the crawler device 10 in the vertical direction, and the rotation transmission wheels 15A and 15B. Can reliably contact the tire 21 and transmit the rotation of the tire 21 to the crawler 11.
 次に、本発明の実施例2を説明する。図16は、実施例2の車両20に装着されたクローラ装置10の斜視図である。 Next, Example 2 of the present invention will be described. FIG. 16 is a perspective view of the crawler device 10 mounted on the vehicle 20 of the second embodiment.
 クローラ装置10は車両20の各タイヤ21に装着される。図16に示す車両20は四つのタイヤ21を有し、各タイヤにクローラ装置10が装着される。例えば、車両20は、四輪駆動の乗用車である。 The crawler device 10 is attached to each tire 21 of the vehicle 20. The vehicle 20 shown in FIG. 16 has four tires 21, and the crawler device 10 is attached to each tire. For example, the vehicle 20 is a four-wheel drive passenger car.
 クローラ装置10はタイヤ21の回転に伴ってクローラ11が駆動して、車両20が柔らかい地面及び雪道等を走行可能にするものである。 The crawler device 10 drives the crawler 11 with the rotation of the tire 21 so that the vehicle 20 can travel on a soft ground, a snowy road, and the like.
 クローラ装置10は、クローラ11、フレーム12、及びタイヤ移動規制部16を有する。 The crawler device 10 includes a crawler 11, a frame 12, and a tire movement restriction unit 16.
 フレーム12は複数の転動輪14を支持し、クローラ11は複数の転動輪14(転動輪14A、14H)の間に巻き掛けされる。フレーム12は、クローラ11が駆動可能な方向に長手方向を有する。複数の転動輪14は、フレーム12の長手方向に並んで、フレーム12に軸支される。 The frame 12 supports a plurality of rolling wheels 14, and the crawler 11 is wound around the plurality of rolling wheels 14 (rolling wheels 14A and 14H). The frame 12 has a longitudinal direction in a direction in which the crawler 11 can be driven. The plurality of rolling wheels 14 are axially supported by the frame 12 along the longitudinal direction of the frame 12.
 フレーム12は、第1回転伝達輪15A及び第2回転伝達輪15Bを支持する。第1回転伝達輪15A及び第2回転伝達輪15Bはクローラ11の上方に位置し、クローラ装置10が車両20に装着された場合、二つの回転伝達輪15A及び15Bは、タイヤ21とクローラ11との間に位置し、タイヤ21及びクローラ11に接触する。第1回転伝達輪15A及び第2回転伝達輪15Bは、それぞれ、前方向及び後方向からタイヤ21に接触することによって、タイヤ21を前後から挟持することとなる。第1回転伝達輪15A及び第2回転伝達輪15Bがタイヤ21の回転に伴って回転することによって、タイヤ21の回転をクローラ11に伝達して、クローラ11を駆動させる。 The frame 12 supports the first rotation transmission wheel 15A and the second rotation transmission wheel 15B. When the first rotation transmission wheel 15A and the second rotation transmission wheel 15B are located above the crawler 11 and the crawler device 10 is mounted on the vehicle 20, the two rotation transmission wheels 15A and 15B are connected to the tire 21 and the crawler 11. Between the tire 21 and the crawler 11. The first rotation transmission wheel 15A and the second rotation transmission wheel 15B contact the tire 21 from the front direction and the rear direction, respectively, thereby sandwiching the tire 21 from the front and rear. The first rotation transmission wheel 15 </ b> A and the second rotation transmission wheel 15 </ b> B rotate with the rotation of the tire 21 to transmit the rotation of the tire 21 to the crawler 11 and drive the crawler 11.
 フレーム12は、第1フレーム12A及び第2フレーム12Bによって構成される。第1フレーム12Aは第1回転伝達輪15Aを支持し、第2フレーム12Bは第2回転伝達輪15Bを支持する。 The frame 12 includes a first frame 12A and a second frame 12B. The first frame 12A supports the first rotation transmission wheel 15A, and the second frame 12B supports the second rotation transmission wheel 15B.
 第2フレーム12Bは、第2回転伝達輪15Bを車両20の前後方向に移動可能にする回転伝達輪移動可能部17を有する。回転伝達輪移動可能部17は、フレーム連結部171及び転動輪移動可能部172を有する。フレーム連結部171には、第2回転伝達輪15Bと、その下方に位置する二つの転動輪14とが取り付けられており、第2回転伝達輪15Bを第2フレーム12Bが軸支するように連結する。転動輪移動可能部172は、第2回転伝達輪15Bの下方に位置する二つの転動輪14を前後方向に移動可能にする。具体的には、転動輪移動可能部172は、第2フレーム12Bの前後方向に横長に形成された穴部である。このため、第2回転伝達輪15Bが前後方向に移動すると、二つの転動輪14も転動輪移動可能部172を移動することになる。本実施例では、移動可能な回転伝達輪を有するフレームを第2フレーム12Bと記載する。 The second frame 12B includes a rotation transmission wheel movable portion 17 that allows the second rotation transmission wheel 15B to move in the front-rear direction of the vehicle 20. The rotation transmitting wheel movable part 17 includes a frame connecting part 171 and a rolling wheel movable part 172. A second rotation transmission wheel 15B and two rolling wheels 14 located below the second rotation transmission wheel 15B are attached to the frame connecting portion 171 and the second rotation transmission wheel 15B is connected so that the second frame 12B is pivotally supported. To do. The rolling wheel movable part 172 enables the two rolling wheels 14 located below the second rotation transmission wheel 15B to move in the front-rear direction. Specifically, the rolling wheel movable part 172 is a hole formed in a horizontally long direction in the front-rear direction of the second frame 12B. For this reason, if the 2nd rotation transmission wheel 15B moves to the front-back direction, the two rolling wheels 14 will also move the rolling-wheel movable part 172. In the present embodiment, a frame having a movable rotation transmission wheel is described as a second frame 12B.
 第1回転伝達輪15Aの回転軸151A(図17参照)及び第2回転伝達輪15Bの回転軸151B(図17参照)は、長さが調整可能な棒状の連結部19によって連結される。第1回転伝達輪15Aの回転軸151Aと第2回転伝達輪15Bの回転軸151Bとの間の距離が連結部19によって一定に保たれ、移動可能な第2回転伝達輪15Bの位置決めがされ、車両20の走行時に第2回転伝達輪15Bが移動してしまうことを防止できる。 The rotation shaft 151A (see FIG. 17) of the first rotation transmission wheel 15A and the rotation shaft 151B (see FIG. 17) of the second rotation transmission wheel 15B are connected by a rod-like connection portion 19 whose length can be adjusted. The distance between the rotation shaft 151A of the first rotation transmission wheel 15A and the rotation shaft 151B of the second rotation transmission wheel 15B is kept constant by the connecting portion 19, and the movable second rotation transmission wheel 15B is positioned. It is possible to prevent the second rotation transmission wheel 15B from moving when the vehicle 20 is traveling.
 連結部19の長さをタイヤ21の直径に合わせた長さに調整することによって、第2回転伝達輪15Bの回転軸151Bがタイヤ21の直径に合わせた位置まで移動するので、連結部19の長さを調整するだけで、第2回転伝達輪15Bの位置を調整することは不要となる。 By adjusting the length of the connecting portion 19 to the length matched to the diameter of the tire 21, the rotation shaft 151 </ b> B of the second rotation transmission wheel 15 </ b> B moves to a position matched to the diameter of the tire 21. It is not necessary to adjust the position of the second rotation transmission wheel 15B simply by adjusting the length.
 タイヤ移動規制部16は、クローラ装置10に対するタイヤ21の移動を規制する。タイヤ移動規制部16の詳細は図19及び図21で説明する。 The tire movement restricting unit 16 restricts the movement of the tire 21 with respect to the crawler device 10. Details of the tire movement restricting portion 16 will be described with reference to FIGS. 19 and 21.
 クローラ11は、センタークローラ111、センタークローラ111の両端に位置する二つのサイドクローラ112A及び112Bによって構成される。サイドクローラ112A及び112Bを総称する場合、サイドクローラ112と記載する。 The crawler 11 includes a center crawler 111 and two side crawlers 112A and 112B located at both ends of the center crawler 111. The side crawlers 112A and 112B are collectively referred to as a side crawler 112.
 図17は、実施例2のタイヤ21の回転がクローラ11に伝達するまでの説明図である。 FIG. 17 is an explanatory diagram until the rotation of the tire 21 according to the second embodiment is transmitted to the crawler 11.
 第1回転伝達輪15A及び第2回転伝達輪15Bは、クローラ装置10が車両20に装着された場合、タイヤ21とクローラ11の間に位置し、タイヤ21に接触するとともにクローラ11にも接触する。 When the crawler device 10 is mounted on the vehicle 20, the first rotation transmission wheel 15 </ b> A and the second rotation transmission wheel 15 </ b> B are located between the tire 21 and the crawler 11 and contact the tire 21 and also the crawler 11. .
 フレーム12には、その長手方向に並ぶように8個の転動輪14A~14Hが軸支される。図4に示すように、第1フレーム12Aは、対向する二つの第1プレート121A(図4参照)及び121B(図4参照)から構成され、第2フレーム12Bは、対向する二つの第2プレート122A(図4参照)及び122Bから構成される。転動輪14A~14Hの回転軸141A~141Hは、第1プレート121Aと第1プレート121Bとの間、及び第2プレート122Aと第2プレート122Bとの間で、その両端を各プレートに軸支されるように配置される。 The eight rolling wheels 14A to 14H are pivotally supported on the frame 12 so as to be aligned in the longitudinal direction. As shown in FIG. 4, the first frame 12A is composed of two opposing first plates 121A (see FIG. 4) and 121B (see FIG. 4), and the second frame 12B is composed of two opposing second plates. 122A (refer FIG. 4) and 122B are comprised. The rotating shafts 141A to 141H of the rolling wheels 14A to 14H are pivotally supported by each plate between the first plate 121A and the first plate 121B and between the second plate 122A and the second plate 122B. Arranged so that.
 第1回転伝達輪15Aは、転動輪14Cと転動輪14Dとの間の空間の上方に位置するクローラ11の外面と接触し、第2回転伝達輪15Bは、転動輪14Eと転動輪14Fとの間の空間の上方に位置するクローラ11の外面と接触する。なお、転動輪14E及び14Fは、第2回転伝達輪15Bとともに、フレーム12Bの長手方向に沿って移動可能な転動輪である。 The first rotation transmission wheel 15A is in contact with the outer surface of the crawler 11 located above the space between the rolling wheel 14C and the rolling wheel 14D, and the second rotation transmission wheel 15B is formed between the rolling wheel 14E and the rolling wheel 14F. It contacts with the outer surface of the crawler 11 located above the space between. The rolling wheels 14E and 14F are rolling wheels that can move along the longitudinal direction of the frame 12B together with the second rotation transmission wheel 15B.
 タイヤ21の回転に伴って第1回転伝達輪15A及び第2回転伝達輪15Bが回転する。第1回転伝達輪15A及び第2回転伝達輪15Bが回転すると、第1回転伝達輪15A及び第2回転伝達輪15Bに接触するクローラ11は、第1回転伝達輪15A及び第2回転伝達輪15Bの回転方向と同じ方向に駆動する。これによって、第1回転伝達輪15A及び第2回転伝達輪15Bは、タイヤ21の回転をクローラ11に伝達して、クローラ11を駆動させる。 As the tire 21 rotates, the first rotation transmission wheel 15A and the second rotation transmission wheel 15B rotate. When the first rotation transmission wheel 15A and the second rotation transmission wheel 15B rotate, the crawler 11 in contact with the first rotation transmission wheel 15A and the second rotation transmission wheel 15B moves to the first rotation transmission wheel 15A and the second rotation transmission wheel 15B. Drive in the same direction as the direction of rotation. Thus, the first rotation transmission wheel 15A and the second rotation transmission wheel 15B transmit the rotation of the tire 21 to the crawler 11 to drive the crawler 11.
 クローラ11のセンタークローラ111の表面には、複数の突起部1111が形成される。また、第1回転伝達輪15A及び第2回転伝達輪15Bは、突起部1111の形成間隔と同じ間隔で複数の溝部152が形成される。なお、突起部1111は、溝部152に係合可能である。これによって、第1回転伝達輪15A及び第2回転伝達輪15Bの回転のクローラ11への伝達効率を向上させることができる。 A plurality of protrusions 1111 are formed on the surface of the center crawler 111 of the crawler 11. Further, the first rotation transmission wheel 15A and the second rotation transmission wheel 15B are formed with a plurality of groove portions 152 at the same interval as the projection portion 1111 is formed. The protrusion 1111 can be engaged with the groove 152. Thereby, the transmission efficiency of the rotation of the first rotation transmission wheel 15A and the second rotation transmission wheel 15B to the crawler 11 can be improved.
 図18は、実施例2のセンタークローラ111の突起部1111の高さとサイドクローラ112の突起部1121の高さとの相違の説明図である。 FIG. 18 is an explanatory diagram of the difference between the height of the protrusion 1111 of the center crawler 111 and the height of the protrusion 1121 of the side crawler 112 according to the second embodiment.
 センタークローラ111の表面には、第1回転伝達輪15A及び第2回転伝達輪15Bに形成された溝部152に係合可能な突起部1111が形成される。また、サイドクローラ112の表面には、突起部1121が形成される。サイドクローラ112の突起部1121の、クローラ11の表面からの高さは、センタークローラ111の突起部1111の、クローラ11の表面からの高さより高い。このように、地面からクローラ11の表面までの高さをサイドクローラ112の突起部1121の高さの分だけ高くすることによって、悪路の走破性を向上させることできる。また、第1回転伝達輪15A及び第2回転伝達輪15Bの溝部152にセンタークローラ111の突起部1111が係合するため、車両20の運転席の地面からの高さを、センタークローラ111の突起部1111の高さを突起部1121の高さにするよりも低くすることができ、運転手の視認性等を向上させることができる。 On the surface of the center crawler 111, a protrusion 1111 that can be engaged with a groove 152 formed in the first rotation transmission wheel 15A and the second rotation transmission wheel 15B is formed. In addition, a protrusion 1121 is formed on the surface of the side crawler 112. The height of the protrusion 1121 of the side crawler 112 from the surface of the crawler 11 is higher than the height of the protrusion 1111 of the center crawler 111 from the surface of the crawler 11. In this way, by increasing the height from the ground to the surface of the crawler 11 by the height of the protrusion 1121 of the side crawler 112, it is possible to improve the running performance on rough roads. Further, since the protrusion 1111 of the center crawler 111 is engaged with the groove 152 of the first rotation transmission wheel 15A and the second rotation transmission wheel 15B, the height of the driver's seat of the vehicle 20 from the ground is determined by the protrusion of the center crawler 111. The height of the portion 1111 can be made lower than the height of the protruding portion 1121, and the driver's visibility and the like can be improved.

 まず、フレーム12の構成について説明する。 First, the configuration of the frame 12 will be described.
 フレーム12は、第1フレーム12A及び第2フレーム12Bを有する。 The frame 12 has a first frame 12A and a second frame 12B.
 第1フレーム12Aは、対向する二つの第1プレート121A及び121Bによって構成される。第1プレート121Aは車両20の外側に位置し、第1プレート121Bは車両20の内側に位置する。 The first frame 12A is composed of two first plates 121A and 121B facing each other. The first plate 121 </ b> A is located outside the vehicle 20, and the first plate 121 </ b> B is located inside the vehicle 20.
 第1回転伝達輪15Aの回転軸151A、転動輪14Aの回転軸141A、転動輪14Bの回転軸141B、及び転動輪14Cの回転軸141Cは、第1プレート121Aと第1プレート121Bとの間で、その両端を各プレートに軸支されるように配置される。 The rotation shaft 151A of the first rotation transmission wheel 15A, the rotation shaft 141A of the rolling wheel 14A, the rotation shaft 141B of the rolling wheel 14B, and the rotation shaft 141C of the rolling wheel 14C are between the first plate 121A and the first plate 121B. The both ends of the plate are pivotally supported by each plate.
 第2フレーム12Bは、対向する二つの第2プレート122A及び122Bによって構成される。第2プレート122Aは車両20の外側に位置し、第2プレート122Bは車両20の内側に位置する。 The second frame 12B includes two opposing second plates 122A and 122B. The second plate 122 </ b> A is located outside the vehicle 20, and the second plate 122 </ b> B is located inside the vehicle 20.
 転動輪14Eの回転軸141E、転動輪14Fの回転軸141F、転動輪14Gの回転軸141G、及び転動輪14Hの回転軸141Hは、第2プレート122Aと第2プレート122Bとの間をで、その両端を各プレートに軸支されるように配置される。 The rotating shaft 141E of the rolling wheel 14E, the rotating shaft 141F of the rolling wheel 14F, the rotating shaft 141G of the rolling wheel 14G, and the rotating shaft 141H of the rolling wheel 14H are between the second plate 122A and the second plate 122B. It arrange | positions so that both ends may be pivotally supported by each plate.
 第1フレーム12Aと第2フレーム12Bとは互いに回動可能に接続される。具体的には、第1フレーム12Aの第1プレート121Aと121Bとの間に、第2フレーム12Bの第2プレート122A及び122Bの第1フレーム12A側の端部が位置する。第2プレート122A及び122Bの第1フレーム12A側の端部には、転動輪14Dの回転軸141Dを挿入するための図示しない貫通穴が設けられている。転動輪14Dの回転軸141Dは、当該貫通穴に挿入され、第1プレート121A及び121Bに取り付けられる。これによって、第1フレーム12A及び第2フレーム12Bは、回転軸141Dを中心にして回動可能となる。 The first frame 12A and the second frame 12B are rotatably connected to each other. Specifically, the end portions on the first frame 12A side of the second plates 122A and 122B of the second frame 12B are located between the first plates 121A and 121B of the first frame 12A. A through hole (not shown) for inserting the rotation shaft 141D of the rolling wheel 14D is provided at the end of the second plate 122A and 122B on the first frame 12A side. The rotating shaft 141D of the rolling wheel 14D is inserted into the through hole and attached to the first plates 121A and 121B. Thus, the first frame 12A and the second frame 12B can be rotated about the rotation shaft 141D.
 これによって、車両20が障害物を乗り越える場合、前方のタイヤ21に装着されたクローラ装置10の第1フレーム12Aが上方向に回動して、クローラ11の前方側の端部と地面との間の距離を大きくすることができ、車両20は、より高い障害物でも乗り越えることが可能となる。 As a result, when the vehicle 20 gets over an obstacle, the first frame 12A of the crawler device 10 mounted on the front tire 21 rotates upward, and the front side end of the crawler 11 and the ground. And the vehicle 20 can get over even higher obstacles.
 なお、転動輪14A~14Hのうち転動輪14Aが地面からの高さが最も高い位置にある。このため、図1に示すように、車両20の前方のタイヤ21には、第1フレーム12Aが前方に位置するようにクローラ装置10を装着し、後方のタイヤ21には、第1フレーム12Aが後方に位置するようにクローラ装置10を装着する。これによって、車両20の前方のタイヤ21に装着されるクローラ装置10においては、クローラ11の前端が最も地面から高くなり、車両20の後方のタイヤ21に装着されるクローラ装置10においては、クローラ11の後端が最も地面から高くなる。このため、車両20は、より高い障害物でも乗り越えことができ、より高い障害物から降りることができる。 Of the rolling wheels 14A to 14H, the rolling wheel 14A is at the highest height from the ground. For this reason, as shown in FIG. 1, the crawler device 10 is mounted on the tire 21 in front of the vehicle 20 so that the first frame 12A is positioned in front, and the first frame 12A is mounted on the rear tire 21. The crawler device 10 is mounted so as to be located rearward. Thereby, in the crawler device 10 mounted on the tire 21 in front of the vehicle 20, the front end of the crawler 11 is highest from the ground, and in the crawler device 10 mounted on the tire 21 in the rear of the vehicle 20, the crawler 11. The rear edge is highest from the ground. For this reason, the vehicle 20 can get over even a higher obstacle, and can get off the higher obstacle.
 また、第2フレーム12Bの第2プレート122A及び122Bは、第1フレーム12A側の端部から転動輪14Gの取付位置までは略直線状に形成され、転動輪14Gの取付位置から転動輪14Hの取付位置までは上方向に向かって折れ曲がるように形成される。 The second plates 122A and 122B of the second frame 12B are formed in a substantially straight line from the end on the first frame 12A side to the mounting position of the rolling wheel 14G, and from the mounting position of the rolling wheel 14G to the rolling wheel 14H. It is formed so as to be bent upward until the mounting position.
 第2プレート122A及び122Bの略直線上に形成された部分には、転動輪移動可能部172となる穴部が第2プレート122A及び122Bの長手方向に形成され、転動輪14Eの回転軸141E及び転動輪14Fの回転軸141Fが転動輪移動可能部172に挿入され、転動輪14E及び転動輪14Fが前後方向に移動可能となる。転動輪移動可能部172となる穴部は、第2プレート122A及び122Bの転動輪14Dの支持位置から転動輪14Gの支持位置までの範囲にわたる長穴として形成される。 In the portion formed on the substantially straight line of the second plates 122A and 122B, a hole portion that becomes the rolling wheel movable portion 172 is formed in the longitudinal direction of the second plates 122A and 122B, and the rotation shaft 141E of the rolling wheel 14E and The rotating shaft 141F of the rolling wheel 14F is inserted into the rolling wheel movable portion 172, so that the rolling wheel 14E and the rolling wheel 14F can move in the front-rear direction. The hole serving as the rolling wheel movable portion 172 is formed as a long hole extending from the support position of the rolling wheel 14D to the support position of the rolling wheel 14G of the second plates 122A and 122B.
 第2プレート122A及び122Bの折り曲げ部分の端部には、転動輪14Hの回転軸141Hが挿入される穴部1221が形成される。穴部1221は、クローラ11の張りの強さを変えるために、転動輪14Hの回転軸141Hが転動輪14Gの回転軸141G側に移動できるように形成される。これによって、例えば、クローラ11をクローラ装置10から取り外す場合、作業者は、転動輪14Hの回転軸141Hを転動輪14Gの回転軸141G側に移動させることによって、クローラ11の張りを弱くすることができるので、クローラ11の取り外し作業の作業性を向上させることができる。 A hole 1221 into which the rotating shaft 141H of the rolling wheel 14H is inserted is formed at the end of the bent portion of the second plates 122A and 122B. The hole 1221 is formed so that the rotating shaft 141H of the rolling wheel 14H can move toward the rotating shaft 141G of the rolling wheel 14G in order to change the tension of the crawler 11. Thus, for example, when removing the crawler 11 from the crawler device 10, the operator may weaken the tension of the crawler 11 by moving the rotation shaft 141H of the rolling wheel 14H to the rotation shaft 141G side of the rolling wheel 14G. Therefore, the workability of the crawler 11 removal work can be improved.
 また、転動輪移動可能部172に挿入された転動輪14Eの回転軸141E及び転動輪14Fの回転軸141Fの端部は、フレーム連結部171に収容される。具体的には、回転軸141E及び141Fの一端部は第2プレート122Aから突出し、車両20の外側に位置するフレーム連結部171に収容され、回転軸141E及び141Fの他端部は第2プレート122Bから突出し、車両20の内側に位置するフレーム連結部171に収容される。 Also, the rotating shaft 141E of the rolling wheel 14E and the end of the rotating shaft 141F of the rolling wheel 14F inserted into the rolling wheel movable portion 172 are accommodated in the frame connecting portion 171. Specifically, one end portions of the rotating shafts 141E and 141F protrude from the second plate 122A and are accommodated in the frame connecting portion 171 located outside the vehicle 20, and the other end portions of the rotating shafts 141E and 141F are the second plate 122B. And is accommodated in a frame connecting portion 171 located inside the vehicle 20.
 次に、第1回転伝達輪15A及び第2回転伝達輪15Bの構成について説明する。 Next, the configuration of the first rotation transmission wheel 15A and the second rotation transmission wheel 15B will be described.
 第1回転伝達輪15Aは二つのローラ153A及び153Bによって構成され、第2回転伝達輪15Bは二つのローラ154A及び154B(図19参照)によって構成される。ローラ153A及び153Bは、回転軸151Aの軸方向に移動可能であり、回転軸151Aの軸方向の所望の位置で回転可能に固定できる。なお、ローラ154A及び154Bも同様である。これによって、タイヤ21の幅に合わせてローラ153Aとローラ153Bとの間の距離、及びローラ154Aとローラ154Bとの間の距離を調整でき、タイヤ21の幅ごとに第1回転伝達輪15A及び第2回転伝達輪15Bを用意する必要がなくなる。 The first rotation transmission wheel 15A is constituted by two rollers 153A and 153B, and the second rotation transmission wheel 15B is constituted by two rollers 154A and 154B (see FIG. 19). The rollers 153A and 153B are movable in the axial direction of the rotating shaft 151A, and can be rotatably fixed at a desired position in the axial direction of the rotating shaft 151A. The same applies to the rollers 154A and 154B. Accordingly, the distance between the rollers 153A and 153B and the distance between the rollers 154A and 154B can be adjusted in accordance with the width of the tire 21, and the first rotation transmission wheel 15A and the first There is no need to prepare the two-rotation transmission wheel 15B.
 ローラ153A及び153Bの第1回転伝達輪15Aの回転軸151Aの軸方向での位置決めについて説明する。長さが調整可能な図示しない間隔調整部材が用意される。間隔調整部材は回転軸151Aを挿入可能な穴部が形成されている。間隔調整部材の長さは、間隔調整部材の穴部に回転軸151Aが挿入されて、間隔調整部材の中心が回転軸151Aの軸方向の中心に位置した場合、ローラ153A及び153Bの外側の側面がタイヤ21の側面と一致する長さに調整される。これによって、ローラ153A及び153Bは、タイヤ21の幅に合わせた距離で回転軸151Aの軸方向で位置決めされる。 The positioning of the rollers 153A and 153B in the axial direction of the rotation shaft 151A of the first rotation transmission wheel 15A will be described. An interval adjusting member (not shown) whose length is adjustable is prepared. The gap adjusting member is formed with a hole into which the rotary shaft 151A can be inserted. The length of the interval adjusting member is such that when the rotary shaft 151A is inserted into the hole of the interval adjusting member and the center of the interval adjusting member is positioned at the center in the axial direction of the rotary shaft 151A, the outer side surfaces of the rollers 153A and 153B Is adjusted to a length that matches the side surface of the tire 21. Accordingly, the rollers 153A and 153B are positioned in the axial direction of the rotation shaft 151A at a distance that matches the width of the tire 21.
 次にタイヤ移動規制部16の構成について説明する。 Next, the configuration of the tire movement restriction unit 16 will be described.
 タイヤ移動規制部16は、外側規制部30及び内側規制部40を有する。図19では、外側規制部30の詳細について説明する。なお、内側規制部40の詳細は図21で説明する。 The tire movement restricting portion 16 includes an outer restricting portion 30 and an inner restricting portion 40. In FIG. 19, the detail of the outer side control part 30 is demonstrated. Details of the inner restricting portion 40 will be described with reference to FIG.
 外側規制部30はY字の上下を逆にした形状である。外側規制部30は、中心部300を中心にして、上方連結部310、第1回転伝達輪連結部320、及び第2回転伝達輪連結部330を有する。 The outer regulating part 30 has a Y-shaped upside down shape. The outer side regulation part 30 has the upper connection part 310, the 1st rotation transmission wheel connection part 320, and the 2nd rotation transmission wheel connection part 330 centering on the center part 300. As shown in FIG.
 上方連結部310は、L字形状をしており、中心部300から車両20の外側でタイヤ21の側面に沿って上方向に延伸する軸311と、軸311の上端からタイヤ21の回転軸と並行に車両20の内側に向かって延伸する軸312とを有する。軸311には、タイヤ21の外側の側面に接触する側面ローラ313が回転可能に取り付けられる。 The upper connecting portion 310 has an L shape, and includes a shaft 311 extending upward along the side surface of the tire 21 outside the vehicle 20 from the center portion 300, and a rotating shaft of the tire 21 from the upper end of the shaft 311. And a shaft 312 extending inward of the vehicle 20 in parallel. A side roller 313 that contacts the outer side surface of the tire 21 is rotatably attached to the shaft 311.
 また、軸312にはタイヤ21の上側の面に接触する上面ローラ314が回転可能に取り付けられる。上面ローラ314は、タイヤ21の上側の面に上方から接触することによって、タイヤ21の上方向の移動を規制する。換言すれば、上面ローラ314は、タイヤ21の第1回転伝達輪15A及び第2回転伝達輪15Bが接触する面と反対側の面に上方から接触する。 Also, an upper surface roller 314 that contacts the upper surface of the tire 21 is rotatably attached to the shaft 312. The upper roller 314 regulates the upward movement of the tire 21 by contacting the upper surface of the tire 21 from above. In other words, the upper surface roller 314 comes into contact with the surface on the opposite side to the surface with which the first rotation transmission wheel 15A and the second rotation transmission wheel 15B of the tire 21 contact from above.
 第1回転伝達輪連結部320は、車両20の外側でタイヤ21の側面に沿って中心部300から第1回転伝達輪15A側に向かって延設され、第1回転伝達輪15A側の端部は第1回転伝達輪15Aの回転軸151Aに連結される。具体的には、第1回転伝達輪連結部320の第1回転伝達輪15A側の下端部には穴部が形成され、第1回転伝達輪15Aの回転軸151Aが当該穴部に挿入されることによって、第1回転伝達輪連結部320が回転軸151Aを軸支するように連結される。また、第1回転伝達輪連結部320には、タイヤ21の外側の側面に接触する側面ローラ321が回転可能に取り付けられる。 The first rotation transmission wheel connecting portion 320 is extended from the center portion 300 toward the first rotation transmission wheel 15A side along the side surface of the tire 21 outside the vehicle 20, and is an end portion on the first rotation transmission wheel 15A side. Is connected to the rotation shaft 151A of the first rotation transmission wheel 15A. Specifically, a hole is formed in the lower end of the first rotation transmission wheel connecting portion 320 on the first rotation transmission wheel 15A side, and the rotation shaft 151A of the first rotation transmission wheel 15A is inserted into the hole. Thus, the first rotation transmission wheel connecting portion 320 is connected so as to support the rotating shaft 151A. Further, a side roller 321 that contacts the outer side surface of the tire 21 is rotatably attached to the first rotation transmission wheel connecting portion 320.
 第2回転伝達輪連結部330は、車両20の外側でタイヤ21の側面に沿って中心部300から第2回転伝達輪15B側に向かって延設され、第2回転伝達輪15B側の端部は第2回転伝達輪15Bの回転軸151Bに連結される。具体的には、第2回転伝達輪連結部330の第2回転伝達輪15B側の下端部には穴部が形成され、第2回転伝達輪15Bの回転軸151Bが当該穴部に挿入されることによって、第2回転伝達輪連結部330が回転軸151Bを軸支するように連結される。また、第2回転伝達輪連結部330には、タイヤ21の外側の側面に接触する側面ローラ331が回転可能に取り付けられる。 The second rotation transmission wheel connecting portion 330 is extended from the center portion 300 toward the second rotation transmission wheel 15B side along the side surface of the tire 21 outside the vehicle 20, and is an end portion on the second rotation transmission wheel 15B side. Is connected to the rotation shaft 151B of the second rotation transmission wheel 15B. Specifically, a hole is formed in the lower end of the second rotation transmission wheel connecting portion 330 on the second rotation transmission wheel 15B side, and the rotation shaft 151B of the second rotation transmission wheel 15B is inserted into the hole. Thus, the second rotation transmission wheel connecting portion 330 is connected so as to support the rotating shaft 151B. Further, a side roller 331 that contacts the outer side surface of the tire 21 is rotatably attached to the second rotation transmission wheel connecting portion 330.
 以上によって、外側規制部30は、第1回転伝達輪連結部320によって第1フレーム12A(回転軸151A)に連結され、第2回転伝達輪連結部330によって第2フレーム12B(回転軸151B)に連結され、上方連結部310の上面ローラ314がタイヤ21の上側の面に上方から接触する。これによって、外側規制部30は、タイヤ21の上方向への移動を規制し、タイヤ21が第1回転伝達輪15A及び第2回転伝達輪15Bから外れることを防止できる。 As described above, the outer restricting portion 30 is connected to the first frame 12A (the rotation shaft 151A) by the first rotation transmission wheel connecting portion 320, and is connected to the second frame 12B (the rotation shaft 151B) by the second rotation transmission wheel connecting portion 330. The upper roller 314 of the upper connecting portion 310 comes into contact with the upper surface of the tire 21 from above. Thereby, the outer side regulation part 30 can control the upward movement of the tire 21, and can prevent the tire 21 from being detached from the first rotation transmission wheel 15A and the second rotation transmission wheel 15B.
 なお、上方連結部310の軸311、第1回転伝達輪連結部320、及び第2回転伝達輪連結部330は、長手方向の長さが調整可能である。例えば、軸311、第1回転伝達輪連結部320、及び第2回転伝達輪連結部330は、二つの棒形状の部材によって構成され、二つの棒形状の部材の一方に雄ねじが形成され、他方に雌ねじが形成される。そして、一方の部材を回すことによって、長手方向の長さが調整される構造を採用可能である。 Note that the length in the longitudinal direction of the shaft 311, the first rotation transmission wheel connection portion 320, and the second rotation transmission wheel connection portion 330 of the upper connection portion 310 can be adjusted. For example, the shaft 311, the first rotation transmission wheel coupling portion 320, and the second rotation transmission wheel coupling portion 330 are configured by two rod-shaped members, and a male screw is formed on one of the two rod-shaped members, while the other An internal thread is formed in And the structure where the length of a longitudinal direction is adjusted by rotating one member is employable.
 また、第1回転伝達輪連結部320、及び第2回転伝達輪連結部330の長手方向の長さは、中心部300がタイヤ21の中心に位置するように、調整されることが望ましい。また、上方連結部310の長手方向の長さは、側面ローラ313がタイヤ21の上側の面に接触するように、調整されることが望ましい。 In addition, it is desirable that the lengths of the first rotation transmission wheel coupling portion 320 and the second rotation transmission wheel coupling portion 330 in the longitudinal direction are adjusted so that the center portion 300 is positioned at the center of the tire 21. Further, the length of the upper connecting portion 310 in the longitudinal direction is desirably adjusted so that the side roller 313 contacts the upper surface of the tire 21.

 このように、内側規制部40は、第1フレーム12A(回転軸151A)及び第2フレーム12B(回転軸151B)に連結されて、第1回転伝達輪連結部410のホイールローラ414、及び第2回転伝達輪連結部420のホイールローラ424がホイールの下側の面に接触するので、タイヤ21の上方向への移動を規制し、タイヤ21が第1回転伝達輪15A及び第2回転伝達輪15Bから外れることを防止できる。 As described above, the inner regulating portion 40 is connected to the first frame 12A (rotating shaft 151A) and the second frame 12B (rotating shaft 151B), the wheel roller 414 of the first rotation transmission wheel connecting portion 410, and the second Since the wheel roller 424 of the rotation transmission wheel connecting portion 420 contacts the lower surface of the wheel, the upward movement of the tire 21 is restricted, and the tire 21 is controlled by the first rotation transmission wheel 15A and the second rotation transmission wheel 15B. Can be prevented from coming off.
 タイヤ21の両側面が側面ローラ313、321、及び331、並びに側面ローラ413及び423によって挟まれるので、タイヤ21の左右方向のずれを規制できる。また、車両20の方向変更時にタイヤ21の向きが変更されると、タイヤ21の向きの変更に伴って、クローラ装置10の向きも変更できる。 Since both side surfaces of the tire 21 are sandwiched between the side rollers 313, 321, and 331 and the side rollers 413 and 423, the lateral displacement of the tire 21 can be restricted. Further, when the direction of the tire 21 is changed when the direction of the vehicle 20 is changed, the direction of the crawler device 10 can be changed along with the change of the direction of the tire 21.
 第1回転伝達輪連結部410、及び第2回転伝達輪連結部420は、長手方向の長さが調整可能である。詳細は、第1回転伝達輪連結部320及び第2回転伝達輪連結部330と同じであるので、説明を省略する。 The length in the longitudinal direction of the first rotation transmission wheel coupling portion 410 and the second rotation transmission wheel coupling portion 420 can be adjusted. The details are the same as those of the first rotation transmission wheel connecting portion 320 and the second rotation transmission wheel connecting portion 330, and thus the description thereof is omitted.
 第1回転伝達輪15Aの回転軸151Aの外側のローラ153Aより車両20の外側の位置には、外側規制部30の第1回転伝達輪連結部320が連結される。また、当該回転軸151Aの第1回転伝達輪連結部320より車両20の外側の位置には、連結部19の一端が連結される。そして、回転軸151Aの車両20の外側の端部は第1フレーム12Aの第1プレート121Aに収容される。同様に、第1回転伝達輪15Aの回転軸151Aの内側のローラ153Bより車両20の内側の位置には、内側規制部40の第1回転伝達輪連結部410が連結される。また、当該回転軸151Aの第1回転伝達輪連結部410より内側の位置には、連結部19の一端が連結される。そして、回転軸151Aの内側の端部は第1フレーム12Aの第1プレート121Bに収容される。これによって、第1フレーム12Aの対向する二つの第1プレート121A及び121B内に、外側規制部30の第1回転伝達輪連結部320、内側規制部40の第1回転伝達輪連結部410、及び二つの連結部19の一端が位置する。 The first rotation transmission wheel connecting portion 320 of the outer regulating portion 30 is connected to a position outside the vehicle 20 from the roller 153A outside the rotation shaft 151A of the first rotation transmission wheel 15A.

 図16~図21では、乗用車のタイヤ21に装着したクローラ装置10について説明したが、図22及び図23では、タイヤ21より直径が大きいトラックのタイヤ22に装着したクローラ装置10について説明する。 16 to 21, the crawler device 10 mounted on the tire 21 of the passenger car has been described. In FIGS. 22 and 23, the crawler device 10 mounted on the tire 22 of the truck having a larger diameter than the tire 21 will be described.
 図22は、実施例2のトラックの前方のタイヤ22に装着されたクローラ装置10のクローラ11を外した状態の外側から見た斜視図である。図23は、実施例2のトラックの前方のタイヤ22に装着されたクローラ装置10のクローラ11を外した状態の内側から見た斜視図である。 FIG. 22 is a perspective view of the crawler device 10 mounted on the tire 22 in front of the truck of Example 2 as viewed from the outside in a state where the crawler 11 is removed. FIG. 23 is a perspective view of the crawler device 10 mounted on the tire 22 in front of the truck according to the second embodiment when viewed from the inside with the crawler 11 removed.
 トラックのタイヤ22は、乗用車のタイヤ21より直径が大きいので、図7に示すように、回転伝達輪移動可能部17によって、第2回転伝達輪15Bを第1回転伝達輪15Aと遠ざかる方向に移動させ、第1回転伝達輪15Aと第2回転伝達輪15Bとの間の距離を長くする必要がある。 Since the tire 22 of the truck is larger in diameter than the tire 21 of the passenger car, the second rotation transmission wheel 15B is moved away from the first rotation transmission wheel 15A by the rotation transmission wheel movable portion 17, as shown in FIG. It is necessary to lengthen the distance between the first rotation transmission wheel 15A and the second rotation transmission wheel 15B.
 連結部19の長さが、トラックのタイヤ22の直径に合わせて調整される。トラックのタイヤ22の直径に合わせて調整された連結部19の長さは、乗用車20のタイヤ21の直径に合わせて調整された連結部19の長さより長くなる。この場合、外側及び内側のフレーム連結部171は、第1回転伝達輪15Aから遠ざかる方向に移動する。これによって、直径が異なるタイヤであっても、第1回転伝達輪15Aと第2回転伝達輪15Bとの間にタイヤを位置させることができ、タイヤの回転を第1回転伝達輪15A及び第2回転伝達輪15Bを介してクローラ11に伝達することができる。 The length of the connecting portion 19 is adjusted according to the diameter of the truck tire 22. The length of the connecting portion 19 adjusted to the diameter of the tire 22 of the truck is longer than the length of the connecting portion 19 adjusted to the diameter of the tire 21 of the passenger car 20. In this case, the outer and inner frame connecting portions 171 move away from the first rotation transmission wheel 15A. As a result, even if the tires have different diameters, the tire can be positioned between the first rotation transmission wheel 15A and the second rotation transmission wheel 15B, and the rotation of the tire can be performed by the first rotation transmission wheel 15A and the second rotation transmission wheel 15B. The rotation can be transmitted to the crawler 11 via the rotation transmission wheel 15B.
 図22に示すように、外側規制部30の中心部300がタイヤ22の中心に位置するように、第1回転伝達輪連結部320及び第2回転伝達輪連結部330の長さを調整する。また、上面ローラ314がタイヤ22の上面に接触するように、軸311の長さを調整する。これによって、直径が異なるタイヤであっても、上面ローラ314をタイヤの上面に接触させることができ、タイヤの上方向の移動を規制できる。 22, the lengths of the first rotation transmission wheel coupling portion 320 and the second rotation transmission wheel coupling portion 330 are adjusted so that the center portion 300 of the outer regulation portion 30 is positioned at the center of the tire 22. Further, the length of the shaft 311 is adjusted so that the upper roller 314 contacts the upper surface of the tire 22. Thereby, even if the tires have different diameters, the upper surface roller 314 can be brought into contact with the upper surface of the tire, and the upward movement of the tire can be restricted.
 図23に示すように、ホイールローラ414がホイールの内周面に接触するように、軸411の長さを調整し、ホイールローラ424がホイールの内周面に接触するように、軸421の長さを調整する。これによって、直径が異なるタイヤであっても、ホイールローラ414及び424をホイールの内周面に接触させることができ、タイヤの上方向の移動を規制できる。 As shown in FIG. 23, the length of the shaft 421 is adjusted so that the wheel roller 414 contacts the inner peripheral surface of the wheel, and the length of the shaft 421 is adjusted so that the wheel roller 424 contacts the inner peripheral surface of the wheel. Adjust the height. Thereby, even if the tire has a different diameter, the wheel rollers 414 and 424 can be brought into contact with the inner peripheral surface of the wheel, and the upward movement of the tire can be restricted.
 フレーム連結部171が移動した場合、第2回転伝達輪15Bとともに転動輪14E及び14Fも移動する。これによって、第2回転伝達輪15Bを移動させても、第2回転伝達輪15Bは、転動輪14Eと転動輪14Fとの中間位置の上方に位置するクローラ11の面に接触する。例えば、第2回転伝達輪15Bが第1回転伝達輪15Aから遠ざかる方向に移動した場合において、第2回転伝達輪15Bが転動輪14Eより転動輪14Fの近くに位置すると、タイヤから下方向の荷重がクローラ11にかかると、クローラ11の転動輪14E側の負荷が大きくなり、クローラ11の耐久性が減少する可能性がある。しかし、本実施例のように、第2回転伝達輪15Bが移動しても、転動輪14Eと転動輪14Fとの中間位置に位置するようにすることで、どちらか一方の転動輪14から遠い方のクローラ11に負荷が大きくかかることを防止でき、クローラ11の耐久性を向上させることができる。 When the frame connecting portion 171 moves, the rolling wheels 14E and 14F also move together with the second rotation transmission wheel 15B. Thereby, even if the second rotation transmission wheel 15B is moved, the second rotation transmission wheel 15B comes into contact with the surface of the crawler 11 located above the intermediate position between the rolling wheel 14E and the rolling wheel 14F. For example, when the second rotation transmission wheel 15B moves away from the first rotation transmission wheel 15A and the second rotation transmission wheel 15B is positioned closer to the rolling wheel 14F than the rolling wheel 14E, a downward load from the tire is applied. When the load is applied to the crawler 11, the load on the rolling wheel 14E side of the crawler 11 is increased, and the durability of the crawler 11 may be reduced. However, as in the present embodiment, even if the second rotation transmission wheel 15B moves, it is far from one of the rolling wheels 14 by being positioned at an intermediate position between the rolling wheels 14E and 14F. It is possible to prevent a large load from being applied to the other crawler 11 and to improve the durability of the crawler 11.
 本実施例によれば、フレーム12が、第2回転伝達輪15Bと第1回転伝達輪15Aとの間の距離を変更可能にするように、第2回転伝達輪15Bの回転軸151Bの位置を車両20(乗用車、トラック、バイク等)の前後方向に移動可能にする回転伝達輪移動可能部17を有する。これによって、第1回転伝達輪15Aと第2回転伝達輪15Bとの間の距離をタイヤの直径に応じて調整可能となり、様々な直径のタイヤに装着可能なクローラ装置10を提供できる。 According to the present embodiment, the position of the rotation shaft 151B of the second rotation transmission wheel 15B is changed so that the frame 12 can change the distance between the second rotation transmission wheel 15B and the first rotation transmission wheel 15A. A rotation transmission wheel movable portion 17 is provided that allows the vehicle 20 (passenger car, truck, motorcycle, etc.) to move in the front-rear direction. Accordingly, the distance between the first rotation transmission wheel 15A and the second rotation transmission wheel 15B can be adjusted according to the diameter of the tire, and the crawler device 10 that can be attached to tires of various diameters can be provided.
 また、本実施例によれば、長さが調整可能であって、第1回転伝達輪15Aの回転軸151Aと第2回転伝達輪15Bの回転軸151Bとが、その長さが調整可能な連結部19によって連結される。これによって、連結部19は、第1回転伝達輪15Aと第2回転伝達輪15Bとの間の距離を自身の長さに保つことができ、タイヤ21に装着した後に第2回転伝達輪15Bが移動してしまうことを防止できる。 Further, according to the present embodiment, the length can be adjusted, and the rotation shaft 151A of the first rotation transmission wheel 15A and the rotation shaft 151B of the second rotation transmission wheel 15B can be adjusted in length. Connected by the part 19. Accordingly, the connecting portion 19 can maintain the distance between the first rotation transmission wheel 15A and the second rotation transmission wheel 15B at its own length, and after the second rotation transmission wheel 15B is mounted on the tire 21, It can prevent moving.
 また、本実施例によれば、回転伝達輪移動可能部17によって回転軸151Bが移動可能にされる第2回転伝達輪15Bは、二つの転動輪14E及び14Fの間のクローラ11の面に接触し、第2フレーム12Bは、二つの転動輪14E及び14Fの回転軸141E及び141Fを移動可能にする転動輪移動可能部172を有する。二つの転動輪14E及び14Fが移動できない場合、第2回転伝達輪15Bは転動輪14E及び14Fの間でしか移動できないが、二つの転動輪14E及び14Fを移動可能とすることによって、第2回転伝達輪15Bの移動可能な範囲を大きくすることができる。 Further, according to this embodiment, the second rotation transmission wheel 15B whose rotation shaft 151B is movable by the rotation transmission wheel movable portion 17 contacts the surface of the crawler 11 between the two rolling wheels 14E and 14F. The second frame 12B has a rolling wheel movable portion 172 that enables the rotation shafts 141E and 141F of the two rolling wheels 14E and 14F to move. When the two rolling wheels 14E and 14F cannot move, the second rotation transmission wheel 15B can move only between the rolling wheels 14E and 14F, but by making the two rolling wheels 14E and 14F movable, the second rotation wheel 15B can move. The movable range of the transmission wheel 15B can be increased.
 また、本実施例によれば、移動可能な転動輪14E及び14Fは、フレーム12に固定された移動しない二つの転動輪(例えば、14D及び14G)の間に位置する。これによって、転動輪14E及び14Fが移動しても、クローラ11の全長を不変とすることができる。 Further, according to the present embodiment, the movable rolling wheels 14E and 14F are located between two non-moving rolling wheels (for example, 14D and 14G) fixed to the frame 12. Thereby, even if the rolling wheels 14E and 14F move, the full length of the crawler 11 can be made unchanged.
 また、本実施例によれば、フレーム12は、移動可能な二つの転動輪14E及び14Fの回転軸141E及び141Fと移動可能な第2回転伝達輪15Bの回転軸151Bとを収容して、移動可能な第2回転伝達輪15Bの回転軸151Bを当該フレーム12に連結するフレーム連結部171を有し、移動可能な第2回転伝達輪15Bの回転軸151Bと当該二つの転動輪14E及び14Fの回転軸141E及び141Fとが一緒に移動する。これによって、第2回転伝達輪15Bが移動しても、第2回転伝達輪15Bと転動輪14E及び14Fとの位置関係を維持することができ、一方の転動輪14から離れたクローラ11の位置に第2回転伝達輪15Bの荷重がかかることを防止できる。 In addition, according to the present embodiment, the frame 12 accommodates and moves the rotational shafts 141E and 141F of the two movable rolling wheels 14E and 14F and the rotational shaft 151B of the movable second rotation transmission wheel 15B. It has a frame connecting portion 171 for connecting the rotation shaft 151B of the second rotation transmission wheel 15B that can be connected to the frame 12, and the rotation shaft 151B of the movable second rotation transmission wheel 15B and the two rolling wheels 14E and 14F. The rotating shafts 141E and 141F move together. Thereby, even if the second rotation transmission wheel 15B moves, the positional relationship between the second rotation transmission wheel 15B and the rolling wheels 14E and 14F can be maintained, and the position of the crawler 11 away from the one rolling wheel 14 can be maintained. It is possible to prevent the second rotation transmission wheel 15B from being loaded.
 また、本実施例によれば、フレーム連結部171は、移動可能な第2回転伝達輪15Bの回転軸151Bを収容する軸受1713と移動可能な二つ転動輪14E及び14Fの回転軸141E及び141Fを収容する軸受1711及び1712とがトラスとなる形状である。これによって、第2回転伝達輪15Bから加わる力を分散することができ、フレーム連結部171の強度を向上させることができる。 Further, according to the present embodiment, the frame connecting portion 171 includes the bearing 1713 that houses the rotating shaft 151B of the movable second rotation transmission wheel 15B and the rotating shafts 141E and 141F of the two movable rolling wheels 14E and 14F. The bearings 1711 and 1712 that house the shape are truss shapes. Thereby, the force applied from the second rotation transmission wheel 15B can be dispersed, and the strength of the frame connecting portion 171 can be improved.
 また、フレーム12は、回転可能に連結された第1フレーム12Aと第2フレーム12Bとを含み、第1フレーム12A及び第2フレーム12Bは、それぞれ回転伝達輪15A及び15Bを有し、第2フレーム12Bは回転伝達輪移動可能部17を有し、第2フレーム12Bが有する第2回転伝達輪15Bが移動可能であって、第1フレーム12Aは、対向する二つの第1プレート121A及び121Bによって構成され、第2フレーム12Bは、対向する二つの第2プレート122A及び122Bによって構成され、第1フレーム12A及び第2フレーム12Bは、第2プレート122A及び122Bの間に、第1プレート121A及び121Bが位置するように連結され、連結部19は、対向する二つの第1プレート121A及び121Bの間、及び対向する二つの第2プレート122A及び122Bの間で二つの回転伝達輪15A及び15Bの回転軸151A及び151Bを連結し、フレーム連結部171が、対向する二つの第2プレート122A及び122Bの向かい合う面と反対側の面に、対向する二つの第1プレート121A及び121Bの向かい合う面と反対側の面がクローラ装置10の最も外側の面となるように、取り付けられる。これによって、全ての部材を第1フレーム12Aの第1プレート121A及び121Bの間、並びにフレーム連結部171の間に収容することができる。 The frame 12 includes a first frame 12A and a second frame 12B that are rotatably connected. The first frame 12A and the second frame 12B have rotation transmission wheels 15A and 15B, respectively. 12B has a rotation transmission wheel movable part 17 and the second rotation transmission wheel 15B of the second frame 12B is movable, and the first frame 12A is constituted by two opposing first plates 121A and 121B.

B, and the rotation shafts 151A and 151B of the two rotation transmission wheels 15A and 15B are connected between the two second plates 122A and 122B facing each other, and the frame connecting portion 171 is connected to the two second plates 122A facing each other. And the opposite surface of the first plates 121A and 121B are attached to the surface opposite to the opposite surface of the first and second plates 122A and 122B so as to be the outermost surface of the crawler device 10. Accordingly, all the members can be accommodated between the first plates 121A and 121B of the first frame 12A and between the frame connecting portions 171.
 また、タイヤ移動規制部16は、タイヤの一方の側面側に位置する第1移動規制部(外側規制部30)とタイヤの他方の側面側に位置する第2移動規制部(内側規制部40)とを有し、第1移動規制部は、タイヤの第1回転伝達輪15A及び第2回転伝達輪15Bが接触する面と反対側の面に接触可能な上面ローラ314と、二つの回転伝達輪15A及び15Bの回転軸151A及び151Bに連結される二つの回転伝達輪連結部320及び330と、を有し、第2移動規制部は、タイヤが装着されるホイールの内周面に接触可能なホイールローラ414及び424と、二つの回転伝達輪15A及び15Bの回転軸151A及び151Bに連結される二つの回転伝達輪連結部410及び420と、を有し、第1移動規制部及び第2移動規制部が有する回転伝達輪連結部320、330、410及び420の長さが調整可能である。これによって、タイヤの直径に合わせて、上面ローラ314を上方からタイヤの面に接触させることができ、ホイールローラ414及び424をホイールの内周面に上方から接触させることができるので、タイヤの上方への移動を確実に規制することができる。 Further, the tire movement restricting portion 16 includes a first movement restricting portion (outer restricting portion 30) located on one side of the tire and a second movement restricting portion (inner restricting portion 40) located on the other side of the tire.

The first rotation transmission wheel coupling portion 320 extends from the shaft coupling portion 340 toward the first rotation transmission wheel 15A, and the end portion on the first rotation transmission wheel 15A side is the rotation shaft 151A of the first rotation transmission wheel 15A. Connected to The second rotation transmission wheel coupling portion 330 extends from the shaft coupling portion 340 toward the second rotation transmission wheel 15B, and the end portion on the second rotation transmission wheel 15B side is the rotation of the second rotation transmission wheel 15B. It is connected to the shaft 151B. Since the opposite side vehicle body connecting portion 13 has the same configuration as that shown in FIG.
 また、本実施例のクローラ装置10は、実施例2の転動輪14Hを有さず、転動輪14A~14Fを有する。これは、バイク25の前方のタイヤ26と後方のタイヤ26との間の距離が、乗用車20及びトラック等と比較して短いためである。また、本実施例のクローラ装置10のクローラ11は、センタークローラ111のみを有するものとするが、実施例2と同じくサイドクローラ112A及び112Bを有してもよい。 Further, the crawler device 10 according to the present embodiment does not include the rolling wheel 14H according to the second embodiment but includes the rolling wheels 14A to 14F. This is because the distance between the front tire 26 and the rear tire 26 of the motorcycle 25 is shorter than that of the passenger car 20 and the truck. Further, the crawler 11 of the crawler device 10 according to the present embodiment includes only the center crawler 111, but may include the side crawlers 112A and 112B as in the second embodiment.
 なお、その他の構成は、実施例2と同じであるので説明を省略する。 Since other configurations are the same as those in the second embodiment, description thereof is omitted.
 次に、バイク25にクローラ装置10を装着する場合について説明する。 Next, a case where the crawler device 10 is mounted on the motorcycle 25 will be described.
 バイク25のタイヤ26の直径は、乗用車20のタイヤ21の直径より小さいので、連結部19の長さは、乗用車20のタイヤ21の直径に合わせて調整された連結部19の長さより短くなる。また、第2回転伝達輪15Bは、乗用車20に装着される場合よりも第1回転伝達輪15A側に位置するように調整される。そして、連結部19の一端を第1回転伝達輪15Aの回転軸151Aに連結するとともに、連結部19の他端を第2回転伝達輪15Bの回転軸151Bに連結する。また、軸連結部340がバイク25の車体の軸と一致するように、第1回転伝達輪連結部320及び第2回転伝達輪連結部330の長さを調整する。以上によって、バイク25にクローラ装置10が装着される。 Since the diameter of the tire 26 of the motorcycle 25 is smaller than the diameter of the tire 21 of the passenger car 20, the length of the connecting portion 19 is shorter than the length of the connecting portion 19 adjusted according to the diameter of the tire 21 of the passenger car 20. Further, the second rotation transmission wheel 15B is adjusted so as to be positioned closer to the first rotation transmission wheel 15A than when the second rotation transmission wheel 15B is attached to the passenger car 20. Then, one end of the connecting portion 19 is connected to the rotating shaft 151A of the first rotation transmitting wheel 15A, and the other end of the connecting portion 19 is connected to the rotating shaft 151B of the second rotation transmitting wheel 15B. Further, the lengths of the first rotation transmission wheel connection portion 320 and the second rotation transmission wheel connection portion 330 are adjusted so that the shaft connection portion 340 coincides with the axis of the motorcycle 25 body. Thus, the crawler device 10 is attached to the motorcycle 25.
 なお、バイク25は前輪駆動しない車種がほとんどであるので、前方のタイヤ26には、クローラ装置10ではなく、そり等が装着されてもよい。 Since most of the motorcycles 25 do not drive the front wheels, the front tire 26 may be equipped with a sled or the like instead of the crawler device 10.
