Abstract

PROBLEM TO BE SOLVED: To maintain smooth engagement between a pinion and a face gear due to grease with simple structure, so as to prevent the postures of the pinion and face gear from being limited.SOLUTION: A gear device includes: a pinion 1 that has a tooth part 3 with at least two strips formed into a spiral shape around a rotational shaft core X, and is supported rotatably forward and backward; a face gear 2 that has a plurality of teeth parts 5 engaged with the pinion 1, and is supported rotatably reciprocatively within a constant angular range; and a wall surface 6 that is formed so that its height is made higher than the plurality of tooth parts 5 on at least one end side in the array direction of the plurality of tooth parts 5.

Description

本発明は、回転軸芯の周りで螺旋状に形成された歯部を有し、正逆に回転自在に支持されたピニオンと、前記ピニオンと噛み合う複数の歯部を有し、一定角度範囲内で往復回転自在に支持されたフェースギアとを備えているギア装置に関する。   The present invention has a tooth portion spirally formed around a rotation axis, has a pinion rotatably supported in the forward and reverse directions, and a plurality of tooth portions meshing with the pinion, and within a certain angle range. It is related with the gear apparatus provided with the face gear supported so that reciprocating rotation is possible.

上記ギア装置は、例えば自動車用エンジンのＡＭＴ（オートマチック・マニュアル・トランスミッション）に装備され、ピニオンとの噛み合いにより一定角度範囲内で往復回転自在に支持されたフェースギアにクラッチ操作部材を連係させて、フェースギアの往復回転に伴うクラッチ操作部材の押し引き動作で、クラッチを入り切りできるように構成してある。   The above gear device is equipped with, for example, an AMT (automatic manual transmission) of an automobile engine, and a clutch operating member is linked to a face gear supported so as to be reciprocally rotatable within a certain angle range by meshing with a pinion. The clutch can be engaged and disengaged by pushing and pulling the clutch operating member accompanying the reciprocating rotation of the face gear.

上記ギア装置では、ピニオンとフェースギアとの噛み合い領域に供給された潤滑用のグリスが、ピニオンの正回転または逆回転に伴って、フェースギアが有する複数の歯部の配列方向の端部、つまり、噛み合い領域から離れた位置に向けて押し出され易い。   In the above gear device, the grease for lubrication supplied to the meshing region between the pinion and the face gear is the end in the arrangement direction of the plurality of tooth portions of the face gear as the pinion rotates forward or backward, that is, It is easy to push out toward a position away from the meshing area.

フェースギアが有する複数の歯部の配列方向の端部に押し出されたグリスは、ピニオンとフェースギアとの噛み合い領域における潤滑に寄与しないので、噛み合い領域に残存するグリスの消耗に伴って円滑な噛み合いを維持できなくなる。   Since the grease pushed out to the end of the plurality of tooth portions of the face gear in the arrangement direction does not contribute to lubrication in the meshing region of the pinion and the face gear, smooth meshing occurs as the grease remaining in the meshing region is consumed. Cannot be maintained.

特許文献１には、水平方向に沿う回転軸芯の周りで正逆に回転自在に支持されたピニオンと、上下方向に沿う回転軸芯の周りで回転自在に支持されたウオームホイールとを備えているギア装置が開示されている。   Patent Document 1 includes a pinion that is rotatably supported around a rotation axis along the horizontal direction and a worm wheel that is rotatably supported around a rotation axis along the vertical direction. A gear device is disclosed.

このギア装置は、ピニオンの歯部の長手方向端部へのグリスの移動を抑制すると共に、ピニオンの歯部の長手方向端部に押し出されたグリスをグリス保持板で受け止めてウオームホイールとの噛み合い領域に掻き寄せるグリス戻し機構を備えている。   This gear device suppresses the movement of the grease to the longitudinal end portion of the pinion tooth portion, and receives the grease pushed out to the longitudinal end portion of the pinion tooth portion by the grease holding plate to mesh with the worm wheel. A grease return mechanism that rakes into the area is provided.

グリス戻し機構が有するグリス保持板は、ウオームホイールの下面側に固定され、外周部を上向きに折り曲げてある折曲部を環状に有する円形の保持板本体と、保持板本体の外周側にピニオンの歯部に噛み合うように突設された多数の噛合部と、保持板本体の折曲部とウオームホイールの歯底との間に配置されるグリス溜部とを有している。   The grease holding plate of the grease return mechanism is fixed to the lower surface side of the worm wheel, and has a circular holding plate body having an annular bent portion with the outer peripheral portion bent upward, and a pinion on the outer peripheral side of the holding plate main body. It has a large number of meshing portions protruding so as to mesh with the tooth portions, and a grease reservoir portion disposed between the bent portion of the holding plate main body and the tooth bottom of the worm wheel.

したがって、正逆に回転自在に支持されたピニオンとの噛み合いにより一定角度範囲内で往復回転自在に支持されたフェースギアを備えているギア装置において、特許文献１に開示されているようなグリス保持板を有するグリス戻し機構を設けて、ピニオンとフェースギアとのグリスによる円滑な噛み合いを維持できるように構成することが考えられる。   Accordingly, in a gear device including a face gear supported so as to be reciprocally rotatable within a certain angle range by meshing with a pinion that is supported so as to be freely rotatable in the forward and reverse directions, a grease holding as disclosed in Patent Document 1 is performed. It is conceivable that a grease return mechanism having a plate is provided so that smooth engagement by the grease between the pinion and the face gear can be maintained.

特開２００９−２４８７２４号公報JP 2009-248724 A

しかしながら、このようなグリス戻し機構を設ける場合は、ピニオンを水平方向に沿う回転軸芯の周りで正逆に回転自在に支持し、フェースギアを歯部が上方に位置する姿勢で上下方向に沿う回転軸芯の周りで回転自在に支持し、そのフェースギアの下面側に固定した保持板本体に、ピニオンの歯部に噛み合う多数の噛合部やグリス溜部を設ける必要がある。   However, in the case of providing such a grease returning mechanism, the pinion is supported so as to be rotatable in the forward and reverse directions around the rotation axis along the horizontal direction, and the face gear is arranged in the vertical direction with the tooth portion positioned upward. It is necessary to provide a large number of meshing portions and grease reservoirs that mesh with the teeth of the pinion on the holding plate body that is rotatably supported around the rotation axis and fixed to the lower surface side of the face gear.

このため、ピニオンやフェースギアの姿勢が制約を受けると共に、構造が複雑化するおそれがある。
本発明は上記実情に鑑みてなされたものであって、ピニオンやフェースギアの姿勢に制約を受け難く、ピニオンとフェースギアとのグリスによる円滑な噛み合いを簡単な構造で維持できるギア装置を提供することを目的とする。 For this reason, the posture of the pinion and the face gear is restricted, and the structure may be complicated.
The present invention has been made in view of the above circumstances, and provides a gear device that is not easily restricted by the attitude of the pinion and the face gear, and that can maintain a smooth meshing of the pinion and the face gear by grease with a simple structure. For the purpose.

本発明によるギア装置の特徴構成は、回転軸芯の周りで螺旋状に形成された少なくとも二条の歯部を有し、正逆に回転自在に支持されたピニオンと、前記ピニオンと噛み合う複数の歯部を有し、一定角度範囲内で往復回転自在に支持されたフェースギアと、前記複数の歯部の配列方向の少なくとも一端側に当該複数の歯部よりも高い高さで形成された壁面と、を備えている点にある。   A characteristic configuration of the gear device according to the present invention includes a pinion that has at least two teeth formed in a spiral shape around a rotation axis and is rotatably supported in the forward and reverse directions, and a plurality of teeth that mesh with the pinion. A face gear that is supported so as to be reciprocally rotatable within a certain angle range, and a wall surface formed at a height higher than the plurality of tooth portions on at least one end side in the arrangement direction of the plurality of tooth portions. , In that it has.

本構成のギア装置は、正逆に回転自在に支持されたピニオンが回転軸芯の周りで螺旋状に形成された少なくとも二条の歯部を有するので、ピニオンとフェースギアとの噛み合い領域における滑りが少なく、ピニオンからフェースギアへの動力の伝達効率が高い。   In the gear device of this configuration, the pinion that is rotatably supported in the forward and reverse directions has at least two tooth portions formed in a spiral shape around the rotation axis, so that slip in the meshing region between the pinion and the face gear is prevented. Less, the power transmission efficiency from pinion to face gear is high.

また、歯部がその回転軸芯の方向に向けて突設されているフェースギアにピニオンが噛み合うので、歯部がその回転軸芯に直交する方向に向けて突設されているウオームホイールに噛み合う場合に比べて、ピニオンとフェースギアとの噛み合い領域に供給されたグリスがフェースギアの回転に伴う遠心力で飛散するおそれが少なく、ピニオンとフェースギアとの噛み合い領域にグリスを長期に亘って保持し易い。   Further, since the pinion meshes with the face gear whose tooth portion projects in the direction of the rotation axis, the tooth portion meshes with the worm wheel projecting in the direction perpendicular to the rotation axis. Compared to the case, the grease supplied to the meshing area of the pinion and the face gear is less likely to be scattered by the centrifugal force accompanying the rotation of the face gear, and the grease is held in the meshing area of the pinion and the face gear for a long time. Easy to do.

一方、ピニオンとフェースギアとの噛み合い領域に供給されたグリスは、ピニオンの正回転または逆回転に伴って、フェースギアが有する複数の歯部の配列方向の端部に向けて押し出され易い。
本構成のギア装置は、フェースギアが有する複数の歯部の配列方向の少なくとも一端側に当該複数の歯部よりも高い高さで形成された壁面を備えている。 On the other hand, the grease supplied to the meshing region between the pinion and the face gear is easily pushed out toward the end in the arrangement direction of the plurality of tooth portions of the face gear as the pinion rotates forward or backward.
The gear device of this configuration includes a wall surface formed at a height higher than the plurality of tooth portions on at least one end side in the arrangement direction of the plurality of tooth portions of the face gear.

このため、複数の歯部の配列方向の少なくとも一端側から配列方向の端部に向けて押し出されようとするグリスを、その一端側に形成された壁面とフェースギアとが交叉する入隅部分に蓄積することができる。
また、万一、ピニオンの回転数が過大でフェースギアの回転角度がオーバーシュートするおそれが生じても、ピニオンと壁面との接触により、フェースギアの回転角度のオーバーシュートを抑制することができる。 For this reason, the grease to be pushed out from at least one end side in the arrangement direction of the plurality of tooth portions toward the end portion in the arrangement direction is applied to the corner portion where the wall surface formed on the one end side and the face gear intersect. Can be accumulated.
Even if the rotation speed of the pinion is excessive and the rotation angle of the face gear may overshoot, the overshoot of the rotation angle of the face gear can be suppressed by contact between the pinion and the wall surface.

入隅部分に蓄積されたグリスは、フェースギアが一定角度範囲の少なくとも一端側に到達する都度、ピニオンが有する歯部に接触して付着する。
ピニオンが有する歯部に付着したグリスは、フェースギアが一定角度範囲の少なくとも一端側から他端側に向けて回転する際に、フェースギアが有する歯部に転移させて、ピニオンとフェースギアとの円滑な噛み合いを維持できる。
つまり、一定角度範囲内で往復回転されるフェースギアを利用して、入隅部分に蓄積されたグリスをピニオンとフェースギアとの噛み合い領域に供給することができる。 Each time the face gear reaches at least one end of the fixed angle range, the grease accumulated in the corner portion comes into contact with and adheres to the tooth portion of the pinion.
The grease adhering to the tooth part of the pinion is transferred to the tooth part of the face gear when the face gear rotates from at least one end side to the other end side in a certain angle range, and the pinion and the face gear Smooth meshing can be maintained.
In other words, the grease accumulated in the corner can be supplied to the meshing area between the pinion and the face gear by using the face gear reciprocally rotated within a certain angle range.

したがって、本構成のギア装置であれば、フェースギアが有する複数の歯部の配列方向の少なくとも一端側に当該複数の歯部よりも高い高さの壁面を形成するという、ピニオンやフェースギアの姿勢に制約を受け難い簡単な構造で、ピニオンとフェースギアとのグリスによる円滑な噛み合いを維持できる。   Therefore, with the gear device of this configuration, the attitude of the pinion or the face gear is such that a wall surface having a height higher than that of the plurality of tooth portions is formed on at least one end side in the arrangement direction of the plurality of tooth portions of the face gear. It is possible to maintain a smooth engagement by the grease between the pinion and the face gear with a simple structure that is not easily restricted by the above.

本発明の他の特徴構成は、前記壁面を、前記ピニオンの回転軸芯と平行に形成してある点にある。   Another feature of the present invention lies in that the wall surface is formed in parallel with the rotational axis of the pinion.

本構成であれば、壁面とフェースギアとが交叉する入隅部分をピニオンの回転軸芯に沿った平行に形成して、入隅部分の全長に亘ってグリスを効率よく蓄積できる。   With this configuration, the corner portion where the wall surface and the face gear intersect is formed in parallel along the rotation axis of the pinion so that grease can be efficiently accumulated over the entire length of the corner portion.

本発明の他の特徴構成は、前記壁面を、前記ピニオンの回転軸芯よりも高く、かつ、前記ピニオンを越えない高さで備えている点にある。   Another feature of the present invention is that the wall surface is provided with a height that is higher than the rotational axis of the pinion and does not exceed the pinion.

本構成であれば、壁面を備えたことによるフェースギアの回転軸芯に沿う方向の寸法増大を防止しながら、入隅部分に蓄積可能なグリス量の増大を図ることができる。   With this configuration, it is possible to increase the amount of grease that can be accumulated in the corner portion while preventing an increase in dimension in the direction along the rotational axis of the face gear due to the provision of the wall surface.

本発明の他の特徴構成は、前記フェースギアが有する歯部から当該フェースギアの径方向に沿って移動するグリスを堰き止め可能な堰き止め部材を、前記ピニオンと一体に回転自在に有している点にある。   According to another aspect of the present invention, there is provided a damming member capable of damming the grease that moves along the radial direction of the face gear from the tooth portion of the face gear, so as to be rotatable integrally with the pinion. There is in point.

本構成であれば、フェースギアが有する歯部から当該フェースギアの径方向に沿ったグリスの移動を抑制して、ピニオンとフェースギアとの噛み合い領域にグリスを保持し易い。   With this configuration, it is easy to hold the grease in the meshing region between the pinion and the face gear by suppressing the movement of the grease along the radial direction of the face gear from the tooth portion of the face gear.

本発明の他の特徴構成は、前記壁面と前記フェースギアとが交叉する入隅部分に、グリスを保持可能なグリス保持部材を装着してある点にある。   Another characteristic configuration of the present invention is that a grease holding member capable of holding grease is attached to a corner portion where the wall surface and the face gear intersect.

本構成であれば、入隅部分に蓄積したグリスを保持し易い。また、万一、ピニオンの回転数が過大で、ピニオンが壁面に接触するおそれが生じても、ピニオンをその接触前にグリス保持部材で受け止めて、ピニオンの破損を防止することができる。   If it is this structure, it will be easy to hold | maintain the grease accumulate | stored in the corner part. Even if the rotation speed of the pinion is excessive and the pinion may come into contact with the wall surface, the pinion can be received by the grease holding member before the contact and the pinion can be prevented from being damaged.

以下に本発明の実施の形態を図面に基づいて説明する。
〔第１実施形態〕
図１〜図４は、例えば自動車用エンジンのＡＭＴに装備される本発明によるギア装置を示す。
ギア装置は、図１に示すように、電動モータＭにより第１回転軸芯Ｘの周りで正逆に駆動回転自在に支持されたピニオン１と、ピニオン１との噛み合いにより、第２回転軸芯Ｙの周りで回転自在に支持された円盤状のフェースギア２とを備えている。
第１回転軸芯Ｘは、第２回転軸芯Ｙに直交する方向に沿う回転軸芯であり、第２回転軸芯Ｙに対してオフセットｄを有する。 Embodiments of the present invention will be described below with reference to the drawings.
[First Embodiment]
1 to 4 show a gear device according to the present invention which is equipped, for example, in an AMT of an automobile engine.
As shown in FIG. 1, the gear device includes a pinion 1 that is supported by an electric motor M so as to be able to be driven to rotate forward and backward around the first rotation axis X, and a pinion 1 that meshes with the second rotation axis. And a disk-shaped face gear 2 rotatably supported around Y.
The first rotation axis X is a rotation axis along a direction orthogonal to the second rotation axis Y, and has an offset d with respect to the second rotation axis Y.

ピニオン１は、第１回転軸芯Ｘの周りで回転自在に支持されるピニオン軸１ａと、ピニオン軸１ａの外周部に第１回転軸芯Ｘの周りで螺旋状に形成された二条の歯部３とを有している。   The pinion 1 includes a pinion shaft 1a that is rotatably supported around the first rotation axis X, and two tooth portions formed in a spiral shape around the first rotation axis X on the outer periphery of the pinion shaft 1a. 3.

フェースギア２は、第２回転軸芯Ｙを中心とする円弧角θが８０°の扇形に形成されたセクタフェースギアで構成され、第２回転軸芯Ｙの周りで回転自在に支持する支軸４が挿通されるボス部２ａと、ピニオン１の歯部３と噛み合う複数の歯部５を形成してあるギア形成部２ｂとを一体に有する。   The face gear 2 is a sector face gear formed in a sector shape with an arc angle θ about 80 ° centered on the second rotation axis Y, and a support shaft that is rotatably supported around the second rotation axis Y. 4 includes a boss portion 2a through which the gear 4 is inserted and a gear forming portion 2b in which a plurality of tooth portions 5 that mesh with the tooth portions 3 of the pinion 1 are formed.

ギア形成部２ｂは、外周部２ｃが第２回転軸芯Ｙを中心とする円弧状の扇形に形成されている。
フェースギア２が有する複数の歯部５は、ギア形成部２ｂの第２回転軸芯Ｙを中心とする外周部２ｃに沿った一定角度範囲に亘って、第２回転軸芯Ｙに沿う方向に向けて突出する状態で帯状に配列されている。 The gear forming portion 2b is formed in an arcuate sector shape with the outer peripheral portion 2c centered on the second rotation axis Y.
The plurality of tooth portions 5 of the face gear 2 are in a direction along the second rotational axis Y over a certain angular range along the outer peripheral portion 2c centering on the second rotational axis Y of the gear forming portion 2b. It is arranged in a strip shape in a state of protruding toward it.

したがって、フェースギア２は、ピニオン１を電動モータＭで正逆に駆動回転させることにより、第２回転軸芯Ｙの周りの一定角度範囲内で往復回転自在に支持されている。
ピニオン１とフェースギア２は、それらの噛み合い領域に塗布したグリスＧで円滑な噛み合いが維持される。 Therefore, the face gear 2 is supported so as to be reciprocally rotatable within a certain angular range around the second rotation axis Y by rotating the pinion 1 forward and backward with the electric motor M.
The pinion 1 and the face gear 2 are maintained in smooth meshing with the grease G applied to their meshing regions.

図２〜図４に示すように、ギア形成部２ｂにおける複数の歯部５の配列方向の一端側と他端側との夫々に壁部７を一体に設けてある。この壁部７の歯部５の側に対向する部分に、複数の歯部５よりも高い高さＨで形成された壁面６をピニオン１の歯部３が壁面６に接触している状態において第１回転軸芯Ｘおよび第２回転軸芯Ｙと平行に備えている。
壁面６は、図４に示すように、第１回転軸芯Ｘの位置よりも高く、かつ、ピニオン１の歯部３の最大外径を越えない高さＨを備えている。 As shown in FIGS. 2-4, the wall part 7 is integrally provided in each of the one end side and other end side of the arrangement direction of the some tooth | gear part 5 in the gear formation part 2b. In the state where the tooth portion 3 of the pinion 1 is in contact with the wall surface 6, the wall surface 6 formed at a height H higher than the plurality of tooth portions 5 is formed on the portion of the wall portion 7 facing the tooth portion 5 side. The first rotation axis X and the second rotation axis Y are provided in parallel.
As shown in FIG. 4, the wall surface 6 has a height H that is higher than the position of the first rotation axis X and does not exceed the maximum outer diameter of the tooth portion 3 of the pinion 1.

したがって、壁面６とフェースギア２とが交叉する入隅部分８に、フェースギア２の往復回転に伴って複数の歯部５の配列方向の一端側および他端側から配列方向の端部に向けて押し出されようとするグリスＧを蓄積することができる。   Therefore, at the corner portion 8 where the wall surface 6 and the face gear 2 intersect, the one end side and the other end side in the arrangement direction of the plurality of tooth portions 5 are directed toward the end portion in the arrangement direction as the face gear 2 reciprocates. The grease G to be pushed out can be accumulated.

オームギア１の歯部３は、フェースギア２が一定角度範囲の一端側又は他端側に到達するまで回転したときに対応する壁面６に最も近接する。
したがって、フェースギア２の回転が一定角度範囲の一端側又は他端側に到達する都度、入隅部分８に蓄積されたグリスＧが、ピニオン１の歯部３に接触して付着する。 The tooth portion 3 of the ohmic gear 1 is closest to the corresponding wall surface 6 when the face gear 2 rotates until it reaches one end side or the other end side of a certain angle range.
Therefore, whenever the rotation of the face gear 2 reaches one end side or the other end side within a certain angle range, the grease G accumulated in the corner portion 8 comes into contact with and adheres to the tooth portion 3 of the pinion 1.

このため、フェースギア２が一定角度範囲の一端側から他端側に向けて回転する際、および、一定角度範囲の他端側から一端側に向けて回転する際に、ピニオン１の歯部３に付着したグリスＧをフェースギア２の歯部５との噛み合い領域に転移させて、ピニオン１とフェースギア２との円滑な噛み合いを維持できる。   For this reason, when the face gear 2 rotates from one end side to the other end side in the constant angle range, and when rotating from the other end side to the one end side in the constant angle range, the tooth portion 3 of the pinion 1 It is possible to maintain the smooth meshing between the pinion 1 and the face gear 2 by transferring the grease G adhering to the meshing region to the meshing region with the tooth portion 5 of the face gear 2.

〔第２実施形態〕
図５は、本発明の別実施形態を示す。
本実施形態のギア装置は、フェースギア２の歯部５からフェースギア２の径方向に移動するグリスＧを堰き止め可能な堰き止め部材９を、ピニオン１の歯部３を挟む位置の夫々に当該ピニオン１と一体に回転自在に有している。 [Second Embodiment]
FIG. 5 shows another embodiment of the present invention.
In the gear device of the present embodiment, the damming member 9 capable of damming the grease G moving in the radial direction of the face gear 2 from the tooth portion 5 of the face gear 2 is disposed at each position where the tooth portion 3 of the pinion 1 is sandwiched. The pinion 1 is integrally rotatable.

堰き止め部材９は、第１回転軸芯Ｘの方向視で円板状に形成してピニオン軸１ａに同芯状に固定され、ピニオン１の回転にかかわらず、フェースギア２の歯部５と干渉（接触）しないように、外周側ほどフェースギア２の歯部５の側から離間する湾曲面形状に形成されている。   The damming member 9 is formed in a disk shape in the direction of the first rotation axis X and is fixed to the pinion shaft 1a so as to be concentric with the tooth portion 5 of the face gear 2 regardless of the rotation of the pinion 1. In order not to interfere (contact), the outer peripheral side is formed in a curved surface shape that is separated from the tooth portion 5 side of the face gear 2.

したがって、フェースギア２の回転に伴う遠心力やグリスＧの自重による、フェースギア２の歯部５からのグリスＧの移動を抑制して、ピニオン１とフェースギア２との噛み合い領域にグリスＧを保持し易い。
その他の構成は第１実施形態と同様である。 Accordingly, the movement of the grease G from the tooth portion 5 of the face gear 2 due to the centrifugal force accompanying the rotation of the face gear 2 or the own weight of the grease G is suppressed, and the grease G is applied to the meshing region between the pinion 1 and the face gear 2. Easy to hold.
Other configurations are the same as those of the first embodiment.

〔第３実施形態〕
図６，図７は、本発明の別実施形態を示す。
本実施形態のギア装置は、壁面６とフェースギア２とが交差する入隅部分８に、フェースギア２の往復回転に伴って蓄積されるグリスＧを保持可能な、例えば軟質の連続気泡発泡樹脂などの多孔質弾性材やフェルトなどの不織布から形成されたグリス保持部材１０を装着してある。このため、グリスＧの保持効果を高めることができる。 [Third Embodiment]
6 and 7 show another embodiment of the present invention.
The gear device of the present embodiment can hold, for example, a soft open-cell foamed resin that can retain grease G accumulated along with reciprocal rotation of the face gear 2 at the corner portion 8 where the wall surface 6 and the face gear 2 intersect. A grease holding member 10 formed of a porous elastic material such as felt or a nonwoven fabric such as felt is attached. For this reason, the retention effect of the grease G can be enhanced.

また、グリス保持部材１０は壁面６の全面に亘って装着してあるので、万一、ピニオン１の歯部３が壁面６に接触するおそれが生じても、その歯部３を接触前にグリス保持部材１０で弾性的に受け止めて、歯部３の破損を防止することができる。
その他の構成は第１又は第２実施形態と同様である。 Further, since the grease holding member 10 is mounted over the entire surface of the wall surface 6, even if the tooth portion 3 of the pinion 1 may come into contact with the wall surface 6, the tooth portion 3 should be greased before contact. The holding member 10 can be elastically received to prevent the tooth portion 3 from being damaged.
Other configurations are the same as those in the first or second embodiment.
