Description

【０００１】
【発明の属する技術分野】
本発明は、ホイールにタイヤを組み付けたときに密着されるホイールのリムフランジ部とタイヤのビード部との間に封じ込まれた空気を除去するタイヤのフィッティング装置及びその方法に関する。
【０００２】
【従来の技術】
車両に装着されたホイールのリムフランジ部と該ホイールに組み付けられたタイヤのビード部との間に空気が封じ込まれていると、車両走行時の振動が大きくなるなど走行性能が低下するので、この部分から空気を排除しておくことが望ましいが、リムフランジ部とビード部との間に空気が入らないように両者を組み付けるのは困難であるので、一般には、組み付け後にいわゆるフィッティングを行って、封じ込められた空気を排除している。
【０００３】
フィッティング装置には、例えば、押圧ローラをタイヤの最大幅員部となる側面部分に押し当てた状態で該側面部分の全周に亘って転がしてリムフランジ部とビード部との間に封じ込まれた空気を排除するものがある（特開平８−１７５１３４号公報参照）。
【０００４】
【発明が解決しようとする課題】
ところが、上記従来例の装置のように、タイヤの最大幅員部に押圧ローラを押し当てて外力を付加すると、最大幅員部より半径方向内方の側面部分が幅方向外側に盛り上がるように変形して、リムフランジ部とビード部との密着部分のうちの外周側の部分の密着状態がむしろ高り、封じ込まれた空気を完全に排除することが困難になることがある。
【０００５】
本発明は、上記問題点に鑑み、リムフランジ部とビード部との間に封じ込まれた空気を確実に排除し得るようにすることを課題とする。
【０００６】
【課題を解決するための手段】
上記課題を解決するため本発明は、ホイールの中心部を挟持する挟持手段と、ホイールに組み付けたタイヤの側面に外力を加える外力付加手段を備えるタイヤのフィティング装置において、外力付加手段を、タイヤの最大幅員部よりもタイヤのビード部側に偏倚したタイヤの内方側面部分に外力を加えるように押圧ローラを有する揺動可能なアームから構成し、アームを揺動させることで、押圧ローラによりタイヤの内方側面部分を連続的に打撃して該部分に外力を加えるようにしている。
【０００７】
この構成によれば、タイヤに対する外力の付加位置がタイヤの最大幅員部よりもビード部側に偏倚しているため、外力によりビード部の外周縁部が確実に凹んで、リムフランジ部とビード部との外周側での相互密着が解除され、相互間に封じ込まれていた空気が、相互密着が解除された部分から抜ける。したがって、外力の付加を止めればビード部とリムフランジ部とが全面的に密着する。この場合に、外力付加手段を、タイヤの内方側面部分の法線方向から外力を加えるように構成すれば、ビード部の外周縁部がより確実に凹み、空気が良く抜ける。
【０００８】
ところで、タイヤの幅方向両側に外力付加手段を配置すれば、タイヤの両側のビード部を同時にフィッティングできる。この場合、タイヤの同一周方向位置で両側から外力を加えたのでは、外力付加方向へのタイヤの変形が他方から付加される外力によって規制されてビード部の外周縁部がうまく凹まなくなる。そのため、幅方向一側の外力付加手段による外力の付加位置と幅方向他方の外力付加手段による外力の付加位置とがタイヤの周方向にずれるように外力付加手段を配置することが望ましい。
【０００９】
また、前記挟持手段に、ホイールを回転させる駆動機構を組込み、ホイールの回転でタイヤのビード部を全周に亘ってフィッティングし得るようにすることが望ましい。更に、タイヤの内圧を標準圧より高圧にしておけば、ビード部の外周縁部を凹ませたときにビード部をリムフランジ部との間に封じ込められた空気を押し出しつつ内周縁側からリムフランジ部に確実に密着させることができ、有利である。
【００１０】
【発明の実施の形態】
図１乃至図３を参照して、１はタイヤＴのフィッティング装置であり、ホイールＨに装着したタイヤＴを該装置のフレーム１ａに設置されるコンベヤ２によりタイヤＴをフィッティング位置（図示されるタイヤの位置）に搬入した後、フィッティング装置１に設置される挟持手段たる上下１対の挟持具５ａ，５ｂによりホイールＨの中央部を挟持し、挟持したタイヤＴの側面の所定部分に外力付加手段７で外力を加えて、タイヤＴのビード部Ｔb （図４参照）とホイールＨのリムフランジ部Ｈf （図４参照）との間に封じ込まれた空気を抜き、タイヤＴをホイールＨにフィッティングさせる。
【００１１】
前記コンベヤ２は、フィッティング位置の上流側及びフィッティング位置では、いずれも間隔を存して並列配置される１対のコンベヤからなるものであり、図２及び図３に表示されるタイヤ搬送方向Ｄにタイヤを搬送するものである。
【００１２】
このうちフィッティング位置の上流側の１対のコンベヤの間には、タイヤＴをフィッティング位置に１つずつ搬入する、いわゆる切り出し機構としてのシーソー部材８が設置されている。シーソー部材８は、その長手方向中央部において揺動自在に軸支されており、その両端部に突起８ａ，８ｂが設けられている。このシーソー部材８をシリンダ８ｃにより作動させて、タイヤ搬送方向下流側の突起８ａをコンベヤ２の搬送面Ｓ上に突出させると、該突起８ａによりタイヤ搬送方向下流側へのタイヤＴの搬送が規制される。そしてその後シリンダ８ｃにより突起８ａを没動させると、シーソー部材８の直上に位置する１つのタイヤＴだけがコンベヤ２によりフィッティング位置に搬入される。つまり突起８ａを没動させるとタイヤ搬送方向上流側の突起８ｂが搬送面Ｓより上側に突出するので、これにより残りのタイヤ（図示せず）のタイヤ搬送方向下流側への搬送が規制される。
【００１３】
挟持手段の一方たる下側挟持具５ａは、フィッティング位置の直下のフレーム１ａに設置されている。下側挟持具５ａは、フレーム１ａに固定したホルダ９に上下方向に摺動自在に保持される円筒形状の昇降体１０を備えており、フレーム１ａに垂設される１対のシリンダ１１，１１のロッド１１ａ，１１ａを昇降体１０の下端のフランジ部１０ａに連結して、該シリンダ１１，１１により昇降体１０を昇降させている。
【００１４】
昇降体１０内には軸受（図示せず）を介して回転自在に回転軸１２が保持されており、回転軸１２の上端には、フィッティング位置に搬入されたタイヤＴのホイールＨにその下側から当接してこれを保持する下側保持部材１３が取り付けられている。一方、回転軸１２の下端には傘歯車１４が取り付けられている。該傘歯車１４には、昇降体１０の下部のフレーム部１０ｂに取り付けたモータＭ１の回転出力を伝達する動力伝達軸１５の先端に設けた傘歯車１６がかみ合わされており、モータＭ１を作動させると下側保持部材１３が回転する。
【００１５】
他方、上側挟持具５ｂは、下側挟持具５ａの上方の、コンベヤ２を挟んで下側挟持具５ａと対向する位置に設置されている。該上側挟持具５ｂは、シリンダ１７により昇降される可動枠１８を備えており、該可動枠１８にはホイールＨの上側に当接して下側保持部材１３との協働によりホイールＨを挟持する上側保持部材１９がベアリング（図示せず）を介して回転自在に取り付けられている。
【００１６】
外力付加手段７は、フィッティング位置の上下に２個宛設置されている。各外力付加手段７は、支持枠７ａに揺動自在に軸支したアーム７ｂと、アーム７ｂの先端に取り付けた押圧ローラ７ｃとを備えており、押圧ローラ７ｃをタイヤの側面の所定部分、即ち、図４（Ａ）に示す如く、タイヤＴの最大幅員部Ｔw よりもタイヤのビード部Ｔb 側に偏倚したタイヤの内方側面部分Ｔp に当接させるようになっている。上側の２つの外力付加手段７，７は、押圧ローラ７ｃのタイヤＴとの当接位置が、タイヤ搬送方向Ｄに対して直角の方向について、互いにタイヤＴの回転軸対称位置になるように設置され、一方、下側の２つの外力付加手段７，７は、押圧ローラ７ｃのタイヤＴとの当接位置が、タイヤ搬送方向Ｄｎｉついて、互いにタイヤＴの回転軸対称位置になるように設置されている（図４参照）。尚、図２ではタイヤ搬送方向Ｄの上流側に位置する下側の外力付加手段を省略している。
【００１７】
このように、タイヤＴの同一周方向位置で両側から外力が加わることがないように、各外力付加手段７を設置すれば、外力付加方向へのタイヤＴの変形が他方から付加される外力によって規制されることがないので、タイヤＴを十分に変形させて、ビード部Ｔb とリムフランジ部Ｈf との密着部の外周側の密着を解除し、両者間に封じ込められた空気を確実に抜くことができる。
【００１８】
各支持枠７ａには、アーム７ｂの後端に付勢力を加える付勢手段たるバネ２１が取り付けられており、各バネ２１により各アーム７ｂを押圧ローラ７ｃがタイヤＴに近接する向きに付勢している。また各支持枠７ａには、バネ２１の付勢力に抗して押圧ローラ７ｃがタイヤＴから離間する向きにアーム７ｂを揺動させるカム２２が設置されている。カム２２には傘歯車等の動力伝達機構２３を介してモータＭ２の出力軸が連結されており、モータＭ２を作動させて、押圧ローラ７ｃをタイヤＴに押し付けた状態にしたり、タイヤＴから離間させた状態にしたりする。
【００１９】
尚、アーム７ｂとバネ２１との間にはロードセル２４が介挿されており、これによりアーム７ｂに付加される付勢力を検知し、押圧ローラ７ｃがタイヤＴに付加する外力の大きさを管理している。また、各支持枠７ａは、フィッティング位置に位置決めされたタイヤＴの半径方向に一致する方向に延びるガイドレール２５上に移動自在に設置されており、アクチュエータ２６により支持枠７ａをガイドレール２５に沿って移動させて、フィッティング位置に搬入されたタイヤＴの大きさに拘らず、常に押圧ローラ７ｃをタイヤの内方側面部分Ｔp に当接させることができるようになっている。更に各押圧ローラ７ｃは、アーム７ｂの長手方向が回転軸となるように回転自在に取り付けられており、回転しているタイヤＴに押し付けられると、該タイヤＴに合わせて連れ回りながら外力を付加する。
【００２０】
以上の構成によれば、コンベヤ２によりフィッティング装置１内に搬入されたタイヤＴが、まずシーソー部材８により１つずつフィッティング位置に搬入される。その後図１及び図２において二点鎖線で示される位置に移動された上下１対の保持部材１３，１９によりホイールＨが挟持され、モータＭ１の作動により下側保持部材１３が回転されると、この回転に合わせてタイヤＴが連れ回る。尚、タイヤＴを挟持する際は、タイヤＴを位置決めする手段を用いて迅速確実にタイヤＴをフィッティング位置に位置決めするのが望ましい。またコンベヤ２は所定の隙間を空けて左右に配置される１対のコンベヤから構成されており、ホイールＨを下側から保持する下側保持部材１３の上下動がコンベヤ２により制限されることはない。
【００２１】
このように保持部材１３，１９によりタイヤを保持した状態で（図４（Ａ）参照）、カム２２を回転させてアーム７ｂを揺動させることで、押圧ローラ７ｃによりタイヤの内方側面部分Ｔp を連続的に打撃して該部分Ｔp に外力を加える（図４（Ｂ）参照）。この外力により、タイヤのビーム部Ｔb の外周縁部が凹まされて、ホイールＨのリムフランジ部Ｈf とタイヤＴのビーム部Ｔb との密着部分のうちの外周側の部分の密着が解除され、該密着が解除された部分からリムフランジ部Ｈf とビーム部Ｔb との間に封じ込まれた空気が抜ける（図４（Ｃ）参照）。尚、カム２２を所定の位相に保持し、押圧ローラ７ｃによりタイヤＴの内方側面部分Ｔp に継続して外力を加えて上記封じ込まれた空気を抜くこともできる。
【００２２】
ところで、本実施形態では、各アーム７ｂを「く」の字形に屈曲させて、タイヤの内方側面部分Ｔp に法線方向から押圧ローラ７ｃの外力が加わるようにしたので、該部分Ｔp をより効果的に凹ませることができ、より確実に前述の密着部分の外周側の部分の密着を解除して封じ込まれた空気を抜くことができ、密着させるべき該密着部分をより確実に密着させることができる。
【００２３】
尚、押圧ローラ７ｃによりタイヤＴに外力を加えてフィッティングを行う際に、タイヤＴの内圧を標準圧より高圧にしておくと、ホイールのリムフランジ部Ｈf とタイヤのビード部Ｔb との間に封じ込まれた空気をより確実に抜くことができ有利である。
【００２４】
また本実施形態では、バネ２１の付勢力を利用して押圧ローラ７ｃをタイヤＴに押し付けているが、バネにより押圧ローラ７ｃがタイヤＴから離間する向きにアーム７ｂを付勢すると共にカムの回転により押圧ローラ７ｃがタイヤＴに近づく向きにアーム７ｂを揺動させるように構成してカムの押し付け力により押圧ローラ７ｃをタイヤＴに押し付けても良く、またシリンダ等の手段を用いて押圧ローラ７ｃをタイヤＴに押し付けるようにしても良い。

BACKGROUND OF THE INVENTION
The present invention relates to a tire fitting apparatus and method for removing air sealed between a rim flange portion of a wheel and a bead portion of the tire that are in close contact when the tire is assembled to a wheel.
[0002]
[Prior art]
If air is sealed between the rim flange part of the wheel mounted on the vehicle and the bead part of the tire assembled to the wheel, the running performance will deteriorate, for example, the vibration during vehicle running will increase. It is desirable to exclude air from this part, but it is difficult to assemble both parts so that air does not enter between the rim flange part and the bead part. Eliminates contained air.
[0003]
In the fitting device, for example, in a state where the pressing roller is pressed against the side surface portion which becomes the maximum width portion of the tire, the roller is rolled over the entire circumference of the side surface portion and sealed between the rim flange portion and the bead portion. There is one that excludes air (see JP-A-8-175134).
[0004]
[Problems to be solved by the invention]
However, as in the above-described conventional device, when an external force is applied by pressing a pressing roller against the maximum width portion of the tire, the side portion radially inward from the maximum width portion is deformed so that it rises outward in the width direction. The contact state of the outer peripheral side portion of the contact portion between the rim flange portion and the bead portion is rather high, and it may be difficult to completely eliminate the enclosed air.
[0005]
In view of the above-described problems, an object of the present invention is to reliably exclude air enclosed between a rim flange portion and a bead portion.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a tire fitting apparatus including clamping means for clamping the central portion of a wheel and external force applying means for applying external force to a side surface of the tire assembled to the wheel. It is composed of a swingable arm having a pressure roller so as to apply an external force to the inner side surface portion of the tire that is biased to the tire bead portion side with respect to the maximum width portion of the tire. The inner side surface portion of the tire is continuously hit to apply an external force to the portion .
[0007]
According to this configuration, since the position where the external force is applied to the tire is biased toward the bead portion with respect to the maximum width portion of the tire, the outer peripheral edge portion of the bead portion is surely recessed by the external force, and the rim flange portion and the bead portion Is released from the part where the mutual contact is released. Therefore, if the application of external force is stopped, the bead portion and the rim flange portion are brought into close contact with each other. In this case, if the external force applying means is configured to apply an external force from the normal direction of the inner side surface portion of the tire, the outer peripheral edge portion of the bead portion is more reliably recessed and the air can be well removed.
[0008]
By the way, if external force applying means are arranged on both sides in the width direction of the tire, the bead portions on both sides of the tire can be fitted simultaneously. In this case, if an external force is applied from both sides at the same circumferential position of the tire, the deformation of the tire in the external force application direction is restricted by the external force applied from the other, and the outer peripheral edge portion of the bead portion does not dent well. For this reason, it is desirable to dispose the external force applying means so that the position where the external force is applied by the external force applying means on one side in the width direction and the position where the external force is applied by the other external force applying means in the width direction are shifted in the tire circumferential direction.
[0009]
Further, it is desirable that a driving mechanism for rotating the wheel is incorporated in the clamping means so that the bead portion of the tire can be fitted over the entire circumference by the rotation of the wheel. Furthermore, if the inner pressure of the tire is set higher than the standard pressure, when the outer peripheral edge portion of the bead portion is recessed, the air sealed between the bead portion and the rim flange portion is pushed out from the inner peripheral edge side while pushing out the air. It is possible to ensure close contact with the portion, which is advantageous.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 to 3, reference numeral 1 denotes a fitting device for a tire T. The tire T mounted on the wheel H is fitted into a fitting position (the illustrated tire) by a conveyor 2 installed on a frame 1a of the device. The center portion of the wheel H is clamped by a pair of upper and lower clamping tools 5a and 5b, which are clamping means installed in the fitting device 1, and an external force applying means is applied to a predetermined portion of the side surface of the sandwiched tire T. 7, external force is applied to remove air trapped between the bead portion Tb (see FIG. 4) of the tire T and the rim flange portion Hf (see FIG. 4) of the wheel H, and the tire T is fitted to the wheel H. Let
[0011]
The conveyor 2 is composed of a pair of conveyors arranged in parallel at an interval between the upstream side of the fitting position and the fitting position, and in the tire conveyance direction D displayed in FIGS. 2 and 3. It conveys tires.
[0012]
Among these, between the pair of conveyors upstream of the fitting position, a seesaw member 8 is installed as a so-called cutting mechanism for carrying the tires T one by one into the fitting position. The seesaw member 8 is pivotally supported at the center in the longitudinal direction, and is provided with projections 8a and 8b at both ends thereof. When the seesaw member 8 is operated by the cylinder 8c and the protrusion 8a on the downstream side in the tire conveyance direction is projected on the conveyance surface S of the conveyor 2, the conveyance of the tire T to the downstream side in the tire conveyance direction is regulated by the protrusion 8a. Is done. Then, when the projection 8a is moved down by the cylinder 8c, only one tire T positioned immediately above the seesaw member 8 is carried into the fitting position by the conveyor 2. That is, when the protrusion 8a is moved down, the protrusion 8b on the upstream side in the tire conveyance direction protrudes upward from the conveyance surface S, thereby restricting the conveyance of the remaining tire (not shown) downstream in the tire conveyance direction. .
[0013]
The lower clamping tool 5a, which is one of the clamping means, is installed on the frame 1a immediately below the fitting position. The lower holding tool 5a includes a cylindrical lifting body 10 that is slidably held in a vertical direction on a holder 9 fixed to the frame 1a, and a pair of cylinders 11 and 11 suspended from the frame 1a. The rods 11a and 11a are connected to the flange portion 10a at the lower end of the lifting body 10, and the lifting body 10 is lifted and lowered by the cylinders 11 and 11.
[0014]
A rotary shaft 12 is rotatably held in the elevating body 10 via a bearing (not shown), and the upper end of the rotary shaft 12 is below the wheel H of the tire T carried into the fitting position. A lower holding member 13 is attached to hold and hold the lower holding member 13. On the other hand, a bevel gear 14 is attached to the lower end of the rotating shaft 12. The bevel gear 14 is meshed with a bevel gear 16 provided at the tip of a power transmission shaft 15 that transmits the rotational output of the motor M1 attached to the lower frame portion 10b of the elevating body 10, and operates the motor M1. And the lower holding member 13 rotate.
[0015]
On the other hand, the upper clamping tool 5b is installed above the lower clamping tool 5a at a position facing the lower clamping tool 5a across the conveyor 2. The upper holding tool 5 b includes a movable frame 18 that is moved up and down by a cylinder 17. The movable frame 18 contacts the upper side of the wheel H and clamps the wheel H in cooperation with the lower holding member 13. An upper holding member 19 is rotatably attached via a bearing (not shown).
[0016]
Two external force applying means 7 are installed at the top and bottom of the fitting position. Each external force adding means 7 includes an arm 7b pivotally supported on the support frame 7a, and a pressing roller 7c attached to the tip of the arm 7b. The pressing roller 7c is a predetermined portion on the side surface of the tire, that is, As shown in FIG. 4 (A), the tire is brought into contact with the inner side surface portion Tp of the tire biased toward the bead portion Tb of the tire with respect to the maximum width portion Tw of the tire T. The upper two external force applying means 7 and 7 are installed so that the contact position of the pressing roller 7c with the tire T is mutually symmetrical with respect to the rotation axis of the tire T in the direction perpendicular to the tire transport direction D. On the other hand, the lower two external force applying means 7 and 7 are installed so that the contact position of the pressing roller 7c with the tire T is symmetrical with respect to the rotation axis of the tire T with respect to the tire transport direction Dni. (See FIG. 4). In FIG. 2, the lower external force applying means located on the upstream side in the tire conveyance direction D is omitted.
[0017]
Thus, if each external force addition means 7 is installed so that external force is not applied from both sides at the same circumferential direction position of the tire T, the deformation of the tire T in the external force addition direction is caused by the external force applied from the other side. Since there is no restriction, the tire T is sufficiently deformed to release the contact between the bead portion Tb and the rim flange portion Hf on the outer peripheral side, and the air trapped between the two is surely removed. Can do.
[0018]
Each support frame 7a is provided with a spring 21 as a biasing means for applying a biasing force to the rear end of the arm 7b. The spring 21 biases each arm 7b in the direction in which the pressing roller 7c approaches the tire T. is doing. Each support frame 7 a is provided with a cam 22 that swings the arm 7 b in a direction in which the pressing roller 7 c is separated from the tire T against the urging force of the spring 21. An output shaft of a motor M2 is connected to the cam 22 via a power transmission mechanism 23 such as a bevel gear, and the motor M2 is operated so that the pressing roller 7c is pressed against the tire T or separated from the tire T. Or let it go.
[0019]
A load cell 24 is inserted between the arm 7b and the spring 21, thereby detecting the urging force applied to the arm 7b and managing the magnitude of the external force applied to the tire T by the pressing roller 7c. is doing. Each support frame 7a is movably installed on a guide rail 25 extending in a direction coinciding with the radial direction of the tire T positioned at the fitting position, and the support frame 7a is moved along the guide rail 25 by an actuator 26. Regardless of the size of the tire T carried into the fitting position, the pressing roller 7c can always be brought into contact with the inner side surface portion Tp of the tire. Further, each pressing roller 7c is rotatably mounted so that the longitudinal direction of the arm 7b becomes a rotation axis. When the pressing roller 7c is pressed against the rotating tire T, an external force is applied while rotating along with the tire T. To do.
[0020]
According to the above configuration, the tires T carried into the fitting device 1 by the conveyor 2 are first carried into the fitting position one by one by the seesaw member 8. After that, when the wheel H is clamped by the pair of upper and lower holding members 13, 19 moved to the position shown by the two-dot chain line in FIGS. 1 and 2, and the lower holding member 13 is rotated by the operation of the motor M1, The tire T is accompanied by this rotation. When sandwiching the tire T, it is desirable to quickly and surely position the tire T at the fitting position using a means for positioning the tire T. The conveyor 2 is composed of a pair of conveyors arranged on the left and right sides with a predetermined gap, and the vertical movement of the lower holding member 13 that holds the wheel H from the lower side is restricted by the conveyor 2. Absent.
[0021]
In this state where the tire is held by the holding members 13 and 19 (see FIG. 4A), the cam 22 is rotated to swing the arm 7b, whereby the inner side surface portion Tp of the tire is pressed by the pressing roller 7c. Are continuously hit to apply an external force to the portion Tp (see FIG. 4B). Due to this external force, the outer peripheral edge of the beam portion Tb of the tire is recessed, and the close contact of the outer peripheral portion of the close contact portion between the rim flange portion Hf of the wheel H and the beam portion Tb of the tire T is released. The air sealed between the rim flange portion Hf and the beam portion Tb is released from the portion where the close contact is released (see FIG. 4C). It is also possible to hold the cam 22 in a predetermined phase and continuously apply an external force to the inner side surface portion Tp of the tire T by the pressing roller 7c to release the enclosed air.
[0022]
By the way, in this embodiment, each arm 7b is bent into a "<" shape so that the external force of the pressing roller 7c is applied to the inner side surface portion Tp of the tire from the normal direction. It is possible to effectively dent, release the sealed air by releasing the contact of the outer peripheral side of the contact portion more reliably, and more securely contact the contact portion to be contacted be able to.
[0023]
Note that when fitting is performed by applying an external force to the tire T by the pressing roller 7c, if the internal pressure of the tire T is set higher than the standard pressure, the tire T is sealed between the rim flange portion Hf of the wheel and the bead portion Tb of the tire. This is advantageous in that the trapped air can be extracted more reliably.
[0024]
In this embodiment, the pressing roller 7c is pressed against the tire T by using the biasing force of the spring 21, but the arm 7b is biased by the spring in the direction in which the pressing roller 7c is separated from the tire T and the cam rotates. Thus, the arm 7b may be swung in a direction in which the pressing roller 7c approaches the tire T, and the pressing roller 7c may be pressed against the tire T by the pressing force of the cam, or the pressing roller 7c may be pressed using a means such as a cylinder. May be pressed against the tire T.
