また、回動軸部３５には、図４及び図５に示すように、両支持片３７，３８間の部位に、側面視略「Ｌ」字状のストッパ４４が溶接されている。ストッパ４４は、回動軸部３５の一方向への回動により、図７（ａ）に示すように、その一端４４ａが、固定基板１８に設けられた貫通孔１９ａを通して固定基板１８の下方まで突出し、前記各係合孔３１，３２，３３のいずれかに係合する規制位置に配置される。また、ストッパ４４は、回動軸部３５の前記とは逆方向への回動により、図７（ｂ）に示すように、その一端４４ａが各係合孔３１〜３３に係合しない解除位置に配置される。なお、ストッパ４４は、その解除位置において、その他端４４ｂが旋回基板１９の上面に当接することでそれ以上の解除側への回動が規制される。   Further, as shown in FIGS. 4 and 5, a stopper 44 having a substantially “L” shape in a side view is welded to the rotating shaft portion 35 at a portion between the support pieces 37 and 38. As shown in FIG. 7A, the stopper 44 is rotated in one direction by the rotation shaft portion 35, and one end 44 a of the stopper 44 passes through the through hole 19 a provided in the fixed substrate 18 to the lower side of the fixed substrate 18. It protrudes and is disposed at a restricting position where it engages with one of the engagement holes 31, 32, 33. Further, as shown in FIG. 7 (b), the stopper 44 is released at a position where one end 44 a is not engaged with each of the engagement holes 31 to 33 due to the rotation of the rotation shaft portion 35 in the opposite direction. Placed in. It should be noted that the stopper 44 is further prevented from rotating toward the release side when the other end 44b abuts against the upper surface of the turning substrate 19 at the release position.

さらに、図４及び図５に示すように、回動軸部３５には、ストッパ４４と第１支持片３７との間に、捻りコイルばね４５が嵌装されている。そして、回動軸部３５は、捻りコイルばね４５の付勢力により一方向に付勢されて、ストッパ４４が前記規制位置に保持されるようになっており、ロックレバー３４の操作軸部３６が捻りコイルばね４５のばね力に抗して図８に示す矢印Ｆ方向に回動操作されることにより規制位置から解除位置に切り替えられる。この実施形態では、各係合孔３１〜３３、ロックレバー３４、ストッパ４４及び捻りコイルばね４５等によりシート固定機構が構成されている。   Further, as shown in FIGS. 4 and 5, a torsion coil spring 45 is fitted to the rotation shaft portion 35 between the stopper 44 and the first support piece 37. The rotating shaft portion 35 is urged in one direction by the urging force of the torsion coil spring 45 so that the stopper 44 is held at the restriction position, and the operation shaft portion 36 of the lock lever 34 is By being operated in the direction of arrow F shown in FIG. 8 against the spring force of the torsion coil spring 45, the restriction position is switched to the release position. In this embodiment, the seat fixing mechanism is configured by the engagement holes 31 to 33, the lock lever 34, the stopper 44, the torsion coil spring 45, and the like.

次に、前記ロックレバー３４の旋回基板１９に組み付ける方法について説明する。
旋回基板１９にロックレバー３４を組み付けるには、まず、ロックレバー３４の回動軸部３５に止め輪４２及びストッパ４４をそれぞれ溶接する。 Next, a method of assembling the lock lever 34 to the turning board 19 will be described.
In order to assemble the lock lever 34 to the turning substrate 19, first, the retaining ring 42 and the stopper 44 are welded to the rotation shaft portion 35 of the lock lever 34.

次に、このロックレバー３４を、図９に示す傾斜状態において、その操作軸部３６の先端側から、右側支持部３９Ｒの挿通孔４０に対して挿通させていく。そして、ロックレバー３４の回動軸部３５を、止め輪４２が第２支持片３８の右側支持部３９Ｒ側の面に近接するようになるまで挿通孔４０に挿通させた後、ロックレバー３４の回動軸部３５の先端側を下げて、図９に二点鎖線で示すように回動軸部３５を第２支持片３８の支持溝３８ａに嵌入させる。この状態で、回動軸部３５に捻りコイルばね４５を嵌装させる。次に、ロックレバー３４を、図９に矢印Ｇで示すように、回動軸部３５の軸線方向に第１支持片３７側に移動させ、回動軸部３５の先端を第１支持片３７の支持孔３７ａに嵌入させる。このとき、捻りコイルばね４５の基端をストッパ４４に係止させるとともに、その先端を第１支持片３７に係止させる。   Next, the lock lever 34 is inserted into the insertion hole 40 of the right support portion 39R from the distal end side of the operation shaft portion 36 in the inclined state shown in FIG. Then, after the rotation shaft portion 35 of the lock lever 34 is inserted through the insertion hole 40 until the retaining ring 42 comes close to the surface on the right support portion 39R side of the second support piece 38, The tip end side of the rotation shaft portion 35 is lowered, and the rotation shaft portion 35 is fitted into the support groove 38a of the second support piece 38 as shown by a two-dot chain line in FIG. In this state, the torsion coil spring 45 is fitted to the rotation shaft portion 35. Next, as indicated by an arrow G in FIG. 9, the lock lever 34 is moved toward the first support piece 37 in the axial direction of the rotation shaft portion 35, and the tip of the rotation shaft portion 35 is moved to the first support piece 37. Is inserted into the support hole 37a. At this time, the base end of the torsion coil spring 45 is locked to the stopper 44 and the tip is locked to the first support piece 37.

最後に、第１支持片３７の支持孔３７ａを挿通した回動軸部３５の先端にスペーサ４３及び止め輪４１を嵌装する。以上の作業により、ロックレバー３４が旋回基板１９に組み付けられる。   Finally, the spacer 43 and the retaining ring 41 are fitted to the tip of the rotation shaft portion 35 inserted through the support hole 37a of the first support piece 37. With the above operation, the lock lever 34 is assembled to the turning substrate 19.

次に、以上のように構成された本実施形態の作用について説明する。
運転シート１４が前向き位置にあるときには、図１０に示すように、捻りコイルばね４５の付勢力によりストッパ４４の一端４４ａが中央係合孔３１に係合し、運転シート１４が前向き位置に固定される。 Next, the operation of the present embodiment configured as described above will be described.
When the operation seat 14 is in the forward position, as shown in FIG. 10, the one end 44a of the stopper 44 is engaged with the central engagement hole 31 by the biasing force of the torsion coil spring 45, and the operation seat 14 is fixed in the forward position. The

車両を停止状態から後進させるときには、運転シート１４の向きを前向き位置から右向き位置に切り替える。運転シート１４が前向き位置にある状態で運転者がロックレバー３４の操作軸部３６を図８におけるＦ方向に回動操作すると、捻りコイルばね４５のばね力に抗して回動軸部３５が回動してストッパ４４が規制位置から解除位置に切り替わり、前向き位置における運転シート１４の固定状態が解除される。このため、この状態で、運転シート１４を前向き位置から右向き位置まで旋回させることができる。運転シート１４を前向き位置から右向き位置側に旋回させていくとき、旋回基板１９が各スライダ３０に対して摺接するとともに各連結ピン２４，２７がそれぞれ各貫通溝２２、２３に沿って移動する。   When the vehicle is moved backward from the stopped state, the direction of the driving seat 14 is switched from the forward position to the right position. When the driver rotates the operation shaft portion 36 of the lock lever 34 in the direction F in FIG. 8 with the operation seat 14 in the forward-facing position, the rotation shaft portion 35 resists the spring force of the torsion coil spring 45. By rotating, the stopper 44 is switched from the restriction position to the release position, and the fixed state of the operation seat 14 in the forward position is released. For this reason, in this state, the driving seat 14 can be turned from the forward position to the right position. When the driving seat 14 is swung from the forward position to the right position side, the swivel board 19 comes into sliding contact with the sliders 30 and the connecting pins 24 and 27 move along the through grooves 22 and 23, respectively.

運転シート１４が右向き位置まで旋回した状態で、図１１に示すように、捻りコイルばね４５の付勢力によってストッパ４４が解除位置から規制位置に切り替わり、ストッパ４４の一端４４ａが左側係合孔３２に係合して運転シート１４が右向き位置に固定される。運転シート１４が右向き位置に固定された状態では、運転者の体が右前側方を向くので、運転者が車両後方を視認し易くなり、車両の後進を容易に行うことができる。   As shown in FIG. 11, the stopper 44 is switched from the release position to the restriction position by the urging force of the torsion coil spring 45 in a state where the operation seat 14 is turned to the rightward position, and one end 44 a of the stopper 44 is moved to the left engagement hole 32. The driving seat 14 is fixed in the rightward position by engaging. In a state where the driving seat 14 is fixed at the right-pointing position, the driver's body faces the front right side, so that the driver can easily see the rear of the vehicle and can easily reverse the vehicle.

また、車両を後進させた後、車両を前進させたり荷役作業を行ったりするときには、運転シート１４の向きを右向き位置から前向き位置に切り替える。この場合も、前向き位置から右向き位置への切替時と同様に、運転者がロックレバー３４を回動操作してストッパ４４を左側係合孔３２から離脱させ、運転シート１４を旋回させることで運転シート１４の向きを切り替えることができる。   Further, after the vehicle is moved backward, when the vehicle is moved forward or a cargo handling operation is performed, the direction of the driving seat 14 is switched from the right position to the forward position. Also in this case, as in the case of switching from the forward position to the right position, the driver rotates the lock lever 34 to disengage the stopper 44 from the left engagement hole 32 and rotate the driving seat 14 to drive the vehicle. The direction of the sheet 14 can be switched.

さらに、運転者が車両から降りるときには、運転シート１４の向きを前向き位置から左向き位置に切り替える。この場合も、前向き位置から右向き位置への切替時と同様に、運転者がロックレバー３４を回動操作してストッパ４４を中央係合孔３１から離脱させ、運転シート１４を旋回させることで運転シート１４の向きを切り替えることができる。運転シート１４が左向き位置まで旋回した状態では、図１２に示すように、ストッパ４４が右側係合孔３３に係合して運転シート１４が左向き位置に固定される。運転シート１４が左向き位置に固定された状態では、運転者の体が左前側方を向くので、昇降ステップ１５を使っての運転シート１４への乗り降りが容易となる。   Furthermore, when the driver gets off the vehicle, the direction of the driving seat 14 is switched from the forward position to the left position. Also in this case, as in the case of switching from the forward position to the right position, the driver rotates the lock lever 34 to release the stopper 44 from the central engagement hole 31 and rotate the driving seat 14 to drive the vehicle. The direction of the sheet 14 can be switched. In a state where the driving seat 14 is turned to the leftward position, as shown in FIG. 12, the stopper 44 is engaged with the right engagement hole 33 and the driving seat 14 is fixed to the leftward position. In the state where the driving seat 14 is fixed at the left-facing position, the driver's body faces the left front side, and thus it is easy to get on and off the driving seat 14 using the lifting step 15.

次に、以上詳述した本実施形態が有する効果を列記する。
（１） 本実施形態のシート旋回機構１６は、金属板材から形成した旋回基板１９に第１支持片３７、第２支持片３８及び右側支持部３９Ｒを一体に形成し、これらによってロックレバー３４を回動可能に支持する。このため、上記特許文献１に記載のロックレバーの支持構造と異なり、旋回基板１９と別部材であるブラケット、支持軸及びカラー等が不要となるため、部品点数及び組立工数を削減することができる。 Next, effects of the present embodiment described in detail above will be listed.
(1) In the sheet turning mechanism 16 of the present embodiment, the first support piece 37, the second support piece 38, and the right support part 39R are integrally formed on the turning board 19 formed of a metal plate, and the lock lever 34 is thereby formed. It is supported so that it can rotate. For this reason, unlike the support structure of the lock lever described in Patent Document 1, a bracket, a support shaft, a collar, and the like, which are separate members from the revolving substrate 19, are not required, so that the number of parts and the number of assembly steps can be reduced. .

（２） 本実施形態のロックレバー３４の組み付け方法は、予めストッパ４４を溶接したロックレバー３４を、操作軸部３６の先端側から右側支持部３９Ｒの挿通孔４０に挿通させた後、第２支持片３８の支持溝３８ａに回動軸部３５を支持させ、次に、第１支持片３７の支持孔３７ａに回動軸部３５の先端側を支持させることで行われる。このため、ロックレバー３４を、回動軸部３５の先端側から、右側支持部３９Ｒの挿通孔４０、第２支持片３８の支持溝３８ａ、第１支持片３７の支持孔３７ａに順に通していくことで支持させた場合と異なり、旋回基板１９に支持させる前のロックレバー３４にストッパ４４を予め溶接することができる。従って、旋回基板１９に支持させた後のロックレバー３４にストッパ４４を溶接する場合と異なり、ロックレバー３４へのストッパ４４の溶接作業を容易に行うことができ、ロックレバー３４の組み付け時間を短縮することができる。   (2) The method of assembling the lock lever 34 according to the present embodiment is the second after the lock lever 34 previously welded with the stopper 44 is inserted from the distal end side of the operation shaft portion 36 into the insertion hole 40 of the right support portion 39R. The rotation shaft portion 35 is supported by the support groove 38 a of the support piece 38, and then the tip end side of the rotation shaft portion 35 is supported by the support hole 37 a of the first support piece 37. For this reason, the lock lever 34 is passed from the distal end side of the rotation shaft portion 35 to the insertion hole 40 of the right support portion 39R, the support groove 38a of the second support piece 38, and the support hole 37a of the first support piece 37 in order. Unlike the case where it is supported by going, the stopper 44 can be welded in advance to the lock lever 34 before being supported by the revolving substrate 19. Therefore, unlike the case where the stopper 44 is welded to the lock lever 34 after being supported by the revolving substrate 19, the welding operation of the stopper 44 to the lock lever 34 can be easily performed, and the time for assembling the lock lever 34 is shortened. can do.

また、ユーザが使用中にロックレバー３４を折り曲げたり、ストッパ４４が摩耗して運転シート１４を確実に固定することができなくなったりしたときに、止め輪４１をロックレバー３４から外すだけで古いロックレバー３４をストッパ４４ごと旋回基板１９から簡単に取り外すことができる。そして、ストッパ４４が溶接された新しいロックレバー３４を簡単に装着することができる。あるいは、捻りコイルばね４５が折れたときには、止め輪４１を外すだけでロックレバー３４をストッパ４４ごと旋回基板１９から簡単に取り外し、新しい捻りコイルばね４５を簡単に装着することができる。従って、ロックレバー３４、ストッパ４４、捻りコイルばね４５等が損傷しても、旋回基板１９自体を新しいものに交換する必要がない。   In addition, when the user bends the lock lever 34 during use, or the stopper 44 wears down and the operation seat 14 cannot be securely fixed, the old lock can be obtained simply by removing the retaining ring 41 from the lock lever 34. The lever 34 and the stopper 44 can be easily detached from the turning board 19. And the new lock lever 34 with which the stopper 44 was welded can be mounted | worn easily. Alternatively, when the torsion coil spring 45 is broken, the lock lever 34 and the stopper 44 can be easily removed from the turning board 19 by simply removing the retaining ring 41, and a new torsion coil spring 45 can be easily attached. Therefore, even if the lock lever 34, the stopper 44, the torsion coil spring 45, etc. are damaged, it is not necessary to replace the turning board 19 itself with a new one.
