Description

本発明は駆動装置に関する。 The present invention relates to a drive device.

ゼンマイばねを用いて所定の部材を巻き取ることで、操作対象を操作する駆動装置が知られている。例えば、特許文献１には、ウエビングを巻取軸に層状に巻き取るウエビング巻取装置が開示されている。 A drive device that operates an operation target by winding a predetermined member using a spring is known. For example, Patent Document 1 discloses a webbing winding device that winds webbing around a winding shaft in a layered manner.

この巻取装置は、ウエビング巻取軸に連結されたゼンマイばねと、ゼンマイばねを収容するドラム状の連結部材と、ドラム状の連結部材と共に回転して渦巻状に形成された案内溝を有する制限板と、連結部材と相対回転する円盤状のアダプタとを有している。円盤状のアダプタは、その中心から半径方向に沿って円弧状の透孔が形成され、透孔の近傍には軸受孔が形成されている。円盤状のアダプタには、円弧状の透孔および軸受孔の両方に係合して、軸受孔を中心に円弧状の透孔に沿って移動するレバーが取り付けられる。レバーは、円弧状の透孔に入り込む係合突起を有し、この係合突起は、制限板に設けられた渦巻状の案内溝にも係合する。 This winding device has a limitation having a spring connected to a webbing winding shaft, a drum-shaped connecting member for accommodating the spring, and a guide groove formed in a spiral shape by rotating together with the drum-shaped connecting member. It has a plate and a disk-shaped adapter that rotates relative to the connecting member. The disk-shaped adapter has an arcuate through hole formed along the radial direction from the center thereof, and a bearing hole is formed in the vicinity of the through hole. The disk-shaped adapter is fitted with a lever that engages with both the arc-shaped through-hole and the bearing hole and moves along the arc-shaped through-hole around the bearing hole. The lever has an engaging projection that enters the arcuate through hole, and the engaging projection also engages with the spiral guide groove provided in the limiting plate.

円盤状のアダプタと渦巻状の案内溝を有する制限板とが相対回転すると、レバーの係合突起が案内溝に案内されるとともに、円弧状の透孔に沿って移動する。そして、レバーの係合突起が案内溝の渦巻終端部に達すると、係合突起の移動が制限され、アダプタと制限板との間の相対回転が停止する。 When the disk-shaped adapter and the limiting plate having the spiral-shaped guide groove rotate relative to each other, the engaging protrusion of the lever is guided by the guide groove and moves along the arc-shaped through hole. Then, when the engaging protrusion of the lever reaches the end of the spiral of the guide groove, the movement of the engaging protrusion is restricted, and the relative rotation between the adapter and the limiting plate is stopped.

以下、図面を参照し、本発明の一実施形態の駆動装置を説明する。なお、以下に示す実施形態はあくまで一例であり、本発明の駆動装置は、以下の実施形態に限定されるものではない。 Hereinafter, the driving device according to the embodiment of the present invention will be described with reference to the drawings. The embodiments shown below are merely examples, and the driving device of the present invention is not limited to the following embodiments.

駆動装置１は、図１に示されるように、操作対象（図示せず）が操作される際に回転する回転部材２と、回転部材２を第１の回転方向Ｄ１に付勢する付勢部材３と、回転部材２を第１の回転方向Ｄ１とは逆方向となる第２の回転方向Ｄ２に回転させるために回転部材２に接続された操作部材４とを有している。また、駆動装置１は、回転部材２と連動して回転し、回転部材２が回転する方向に沿って渦巻状に設けられた案内溝５１を有する案内部５と、回転部材２が相対回転するように設けられた基部６とを有している。 As shown in FIG. 1, the drive device 1 includes a rotating member 2 that rotates when an operation target (not shown) is operated, and an urging member that urges the rotating member 2 in the first rotation direction D1. 3 has an operating member 4 connected to the rotating member 2 in order to rotate the rotating member 2 in a second rotation direction D2 opposite to the first rotation direction D1. Further, the drive device 1 rotates in conjunction with the rotating member 2, and the rotating member 2 rotates relative to the guide portion 5 having the guide groove 51 provided in a spiral shape along the direction in which the rotating member 2 rotates. It has a base 6 provided as described above.

駆動装置１は、操作部材４を操作することによって回転部材２を回転させて、操作対象を操作する。操作対象は、回転部材２の回転力によって直接または間接的に操作されるものであれば、特に限定されない。操作対象は、回転部材２の回転力によって回転動作するものであってもよいし、回転部材２の回転力によって、直線動作するものであってもよい。 The drive device 1 rotates the rotating member 2 by operating the operating member 4 to operate the operation target. The operation target is not particularly limited as long as it is directly or indirectly operated by the rotational force of the rotating member 2. The operation target may be one that rotates by the rotational force of the rotating member 2, or may be one that operates linearly by the rotational force of the rotating member 2.

駆動装置１の全体的な構造は、回転部材２が回転することによって、操作対象が操作されるものであれば、図示される構造に限定されない。本実施形態では、駆動装置１は、図１に示されるように、回転部材２に接続された駆動部７と、駆動部７によって回転部材２の回転力が伝達されて作動する回転作動部８とを有している。本実施形態では、回転部材２の回転力が駆動部７を介して回転作動部８に伝達され、回転作動部８に直接または間接的に接続された操作対象が操作される。 The overall structure of the drive device 1 is not limited to the structure shown as long as the operation target is operated by rotating the rotating member 2. In the present embodiment, as shown in FIG. 1, the drive device 1 operates by transmitting the rotational force of the rotary member 2 by the drive unit 7 connected to the rotary member 2 and the drive unit 7. And have. In the present embodiment, the rotational force of the rotary member 2 is transmitted to the rotary actuating unit 8 via the drive unit 7, and the operation target directly or indirectly connected to the rotary actuator 8 is operated.

駆動部７は、従動部材７１と、回転伝達部材７２と、複数のギヤ７３、７４、７５とを備えている。従動部材７１は回転部材２に対して軸Ｘ方向に離間可能であるとともに、回転部材２とともに軸Ｘ周りに回転可能に連結されている。回転伝達部材７２は、従動部材７１が回転部材２に対して軸Ｘ方向に離間したときに従動部材７１と係合して従動部材７１の回転力が伝達される。複数のギヤ７３、７４、７５は、回転伝達部材７２の回転力を回転作動部８に伝達する。回転作動部８は、ギヤ７４またはギヤ７５の回転力が伝達されて回転する作動ギヤ８１と、作動ギヤ８１の回転力が伝達されて回転する作動軸８２とを有している。 The drive unit 7 includes a driven member 71, a rotation transmission member 72, and a plurality of gears 73, 74, 75. The driven member 71 can be separated from the rotating member 2 in the axis X direction, and is rotatably connected to the rotating member 2 around the axis X. The rotation transmission member 72 engages with the driven member 71 when the driven member 71 is separated from the rotating member 2 in the axis X direction, and the rotational force of the driven member 71 is transmitted. The plurality of gears 73, 74, and 75 transmit the rotational force of the rotation transmission member 72 to the rotation actuating portion 8. The rotation actuating portion 8 has an actuating gear 81 to which the rotational force of the gear 74 or the gear 75 is transmitted to rotate, and an actuating shaft 82 to which the rotational force of the actuating gear 81 is transmitted to rotate.

回転部材２が回転すると、まず従動部材７１が回転部材２から、回転部材２の軸Ｘ方向で離間する方向に移動し、係合歯を有する回転伝達部材７２に回転方向で係合可能な位置まで移動する。そして、この状態において、従動部材７１は回転部材２と同方向に回転可能となり、従動部材７１が回転部材２とともに軸Ｘ周りに回転して、回転伝達部材７２を回転させる。回転伝達部材７２が回転すると、複数のギヤ７３、７４、７５を介して、回転作動部８の作動ギヤ８１が回転し、作動ギヤ８１に接続された作動軸８２が回転して、操作対象を操作する。 When the rotating member 2 rotates, the driven member 71 first moves from the rotating member 2 in a direction away from the rotating member 2 in the axis X direction, and is in a position where it can be engaged with the rotation transmitting member 72 having engaging teeth in the rotational direction. Move to. Then, in this state, the driven member 71 can rotate in the same direction as the rotating member 2, and the driven member 71 rotates around the axis X together with the rotating member 2 to rotate the rotation transmitting member 72. When the rotation transmission member 72 rotates, the actuating gear 81 of the rotation actuating unit 8 rotates via the plurality of gears 73, 74, 75, and the actuating shaft 82 connected to the actuating gear 81 rotates to operate the operation target.

It has a switching member 9 for switching to a second connection state (state shown in FIG. 1) connected to the unit 7. Although detailed description of this point will be omitted, each time the outer tube T is operated, the plate-shaped cam is passed through the actuating member 91 connected to the outer tube T and the plate-shaped cam member 92 to which the gear 74 is connected. When the gear 74 connected to the member 92 directly meshes with the working gear 81 (first connection state. The rotational force is transmitted in the order of the gear 73, the gear 74, and the working gear 81), the gear 74 and the working gear 81 It moves between the state of meshing with the meshing gear 75 (second connection state. The rotational force is transmitted in the order of gear 73, gear 74, gear 75, and operating gear 81). As a result, the operation target can be operated in both directions in one direction and the other direction by the operation in one direction of the operation member 4 (for example, the operation target can be opened / closed and moved up / down). ..

なお、上記駆動部７、回転作動部８および切替部材９は、図示された構造に限定されるものではなく、本発明において本質的ではないため、詳細な説明は省略する。 The drive unit 7, the rotation actuating unit 8, and the switching member 9 are not limited to the illustrated structure and are not essential in the present invention, so detailed description thereof will be omitted.

It has a straight portion ST2 that is inclined and extends so as to approach the base end Sb1 of the engaging protrusion Sb, and a bent portion CV that bends and connects the straight portion ST1 and the straight portion ST2.

また、スライド部材Ｓは、図８（Ａ）および（Ｂ）に示されるように構成されていてもよい。図８（Ａ）および（Ｂ）に示されるスライド部材Ｓは、スライド部材Ｓが基部６に取り付けられた状態で、回転部材２の軸Ｘに略垂直な面内で、係合突起Ｓｂの基端Ｓｂ１から、線Ｌに対して垂直な方向に対して傾斜し、かつ、係合突起Ｓｂの基端Ｓｂ１から支軸Ｓａの基端Ｓａ１に近付くように傾斜している。具体的には、連結部Ｓｃは、図８（Ａ）に示されるように、係合突起Ｓｂの基端Ｓｂ１から支軸Ｓａの基端Ｓａ１に近付くように傾斜して延びる直線部ＳＴ３と、支軸Ｓａの基端Ｓａ１から係合突起Ｓｂの基端Ｓｂ１に近付くように傾斜して延びる直線部ＳＴ４と、直線部ＳＴ３と直線部ＳＴ４とを湾曲して繋ぐ曲げ部ＣＶとを有している。なお、スライド部材Ｓは、上述したように、図７および図８の形状に限定されるものではない。 Further, the slide member S may be configured as shown in FIGS. 8A and 8B. The slide member S shown in FIGS. 8A and 8B is a base of the engaging projection Sb in a plane substantially perpendicular to the axis X of the rotating member 2 with the slide member S attached to the base portion 6. It is inclined from the end Sb1 in a direction perpendicular to the line L, and is inclined so as to approach the base end Sa1 of the support shaft Sa from the base end Sb1 of the engaging projection Sb. Specifically, as shown in FIG. 8A, the connecting portion Sc includes a straight portion ST3 extending in an inclined manner from the proximal end Sb1 of the engaging projection Sb so as to approach the proximal end Sa1 of the support shaft Sa. It has a straight portion ST4 that extends inclined from the base end Sa1 of the support shaft Sa so as to approach the base end Sb1 of the engagement projection Sb, and a bent portion CV that bends and connects the straight portion ST3 and the straight portion ST4. There is. As described above, the slide member S is not limited to the shapes shown in FIGS. 7 and 8.

曲げ部ＣＶは、支軸Ｓａと係合突起Ｓｂとを直線的に繋ぐのではなく（図７（Ｂ）の線Ｌに沿って繋ぐのではなく）、湾曲して繋いでいる。曲げ部ＣＶが設けられていることにより、後述するように、係合突起Ｓｂに加わった衝撃を緩和するようにスライド部材Ｓの変形が可能となる。なお、曲げ部ＣＶの形状は、係合突起Ｓｂに加わった衝撃を緩和するようにスライド部材Ｓを変形させることができれば、特に限定されない。本実施形態では、曲げ部ＣＶは１つであるが、複数の曲げ部が設けられていてもよい。 The bent portion CV does not connect the support shaft Sa and the engaging projection Sb linearly (rather than connecting along the line L in FIG. 7B), but bends and connects them. Since the bent portion CV is provided, the slide member S can be deformed so as to alleviate the impact applied to the engaging projection Sb, as will be described later. The shape of the bent portion CV is not particularly limited as long as the slide member S can be deformed so as to alleviate the impact applied to the engaging projection Sb. In the present embodiment, the bending portion CV is one, but a plurality of bending portions may be provided.

本実施形態では、連結部Ｓｃは、係合突起Ｓｂの基端Ｓｂ１から、係合突起Ｓｂの基端Ｓｂ１と支軸Ｓａの基端Ｓａ１とを結んだ線Ｌに対して垂直な成分を含む方向に延びた後、連結部Ｓｃに設けられた曲げ部ＣＶを経由して支軸Ｓａの基端Ｓａ１へと延びている。これにより、回転部材２が基部６に対して相対回転して、係合突起Ｓｂと案内溝５１の端部とが係合して回転部材２の相対回転が停止する際に、スライド部材Ｓの破損を抑制することができる。具体的には、回転部材２が基部６に対して相対回転して、係合突起Ｓｂと案内溝５１の端部とが係合する際に、案内溝５１の端部（本実施形態では、第２の端部５１ｂ）から係合突起Ｓｂに力が加わった際に、スライダ部材Ｓは、曲げ部ＣＶを支点として、連結部Ｓｃのうち曲げ部ＣＶから係合突起Ｓｂまでの間の部分が弾性変形する。したがって、係合突起Ｓｂに案内溝５１の端部から加わる衝撃をスライド部材Ｓ（連結部Ｓｃ）の弾性変形によって吸収することができる。これにより、スライド部材Ｓ、特に係合突起Ｓｂおよび係合突起Ｓｂの基端Ｓｂ１近傍の部位の破損が抑制される。 In the present embodiment, the connecting portion Sc includes a component perpendicular to the line L connecting the proximal end Sb1 of the engaging projection Sb to the proximal end Sb1 of the engaging projection Sb and the proximal end Sa1 of the support shaft Sa. After extending in the direction, it extends to the base end Sa1 of the support shaft Sa via the bending portion CV provided in the connecting portion Sc. As a result, when the rotating member 2 rotates relative to the base portion 6 and the engaging projection Sb and the end portion of the guide groove 51 engage with each other to stop the relative rotation of the rotating member 2, the slide member S Damage can be suppressed. Specifically, when the rotating member 2 rotates relative to the base portion 6 and the engaging projection Sb and the end portion of the guide groove 51 engage with each other, the end portion of the guide groove 51 (in the present embodiment, the end portion). When a force is applied to the engaging protrusion Sb from the second end portion 51b), the slider member S is a portion of the connecting portion Sc between the bent portion CV and the engaging protrusion Sb with the bent portion CV as a fulcrum. Is elastically deformed. Therefore, the impact applied to the engaging projection Sb from the end of the guide groove 51 can be absorbed by the elastic deformation of the slide member S (connecting portion Sc). As a result, damage to the slide member S, particularly the engagement projection Sb and the portion near the base end Sb1 of the engagement projection Sb is suppressed.

以下、本実施形態の駆動装置１における、スライド部材の作用効果をより詳細に説明する。 Hereinafter, the action and effect of the slide member in the drive device 1 of the present embodiment will be described in more detail.

図４（Ａ）および（Ｂ）は、操作部材４が操作されていない初期状態を示している。図４（Ｂ）に示される初期状態から操作部材４を引き操作すると、回転部材２および案内部５が第２の回転方向Ｄ２（図４（Ａ）における反時計方向）に回転する。回転部材２および案内部５が回転すると、係合突起Ｓｂは渦巻状の案内溝５１に入った状態で、円弧溝６１に案内されて、少しずつ円弧溝６１の第１の円弧端部６１ａに近付いていく（図５（Ａ）参照）。さらに操作部材４を操作して、回転部材２および案内部５がさらに回転して、係合突起Ｓｂが渦巻状の案内溝５１内で第１の端部５１ａ側に移動すると、係合突起Ｓｂは円弧溝６１の第１の円弧端部６１ａに到達する（図６（Ａ）参照）。このとき、駆動装置１においては、回転部材２の第２の回転方向Ｄ２への回転によって、駆動部７、回転作動部８を介して操作対象が操作される。なお、本実施形態では、操作部材４が引き切られた状態（図６（Ｂ）参照）で、係合突起Ｓｂは、案内溝５１内で第１の端部５１ａから離れた位置に位置している。しかし、操作部材４が引き切られた状態で、係合突起Ｓｂが案内溝５１の第１の端部５１ａと接触するように構成されていてもよい。 4 (A) and 4 (B) show an initial state in which the operating member 4 is not operated. When the operating member 4 is pulled from the initial state shown in FIG. 4B, the rotating member 2 and the guide portion 5 rotate in the second rotation direction D2 (counterclockwise direction in FIG. 4A). When the rotating member 2 and the guide portion 5 rotate, the engaging protrusion Sb is guided by the arc groove 61 in a state of being in the spiral guide groove 51, and gradually reaches the first arc end portion 61a of the arc groove 61. Approaching (see Fig. 5 (A)). Further, when the operating member 4 is further operated to further rotate the rotating member 2 and the guide portion 5 and the engaging protrusion Sb moves toward the first end portion 51a in the spiral guide groove 51, the engaging protrusion Sb Reaches the first arc end 61a of the arc groove 61 (see FIG. 6A). At this time, in the drive device 1, the operation target is operated via the drive unit 7 and the rotation actuating unit 8 by the rotation of the rotation member 2 in the second rotation direction D2. In the present embodiment, in the state where the operating member 4 is pulled off (see FIG. 6B), the engaging projection Sb is located in the guide groove 51 at a position away from the first end portion 51a. ing. However, the engaging projection Sb may be configured to come into contact with the first end portion 51a of the guide groove 51 in a state where the operating member 4 is pulled off.

図６（Ａ）および（Ｂ）に示される状態から、操作部材４の操作を解除すると、回転部材２と駆動部７との連結が解除されて、回転部材２の回転が操作対象に伝達されなくなる。また、操作部材４の操作が解除されると、付勢部材３の付勢力によって回転部材２が第１の回転方向Ｄ１に回転し、回転部材２から繰り出された操作部材４が回転部材２に巻き取られる。この際、回転部材２とともに案内部５も第２の回転方向Ｄ２に回転し、それに伴い、係合突起Ｓｂは案内溝５１内を第２の端部５１ｂに向かって移動するように案内される。また、係合突起Ｓｂは、円弧溝６１内において、第１の円弧端部６１ａ側から第２の円弧端部６１ｂへ向かって移動する。 When the operation of the operating member 4 is released from the states shown in FIGS. 6A and 6B, the connection between the rotating member 2 and the driving unit 7 is released, and the rotation of the rotating member 2 is transmitted to the operation target. It disappears. Further, when the operation of the operating member 4 is released, the rotating member 2 is rotated in the first rotation direction D1 by the urging force of the urging member 3, and the operating member 4 drawn out from the rotating member 2 becomes the rotating member 2. It is taken up. At this time, the guide portion 5 also rotates in the second rotation direction D2 together with the rotating member 2, and the engaging projection Sb is guided to move in the guide groove 51 toward the second end portion 51b. .. Further, the engaging protrusion Sb moves from the first arc end portion 61a side toward the second arc end portion 61b in the arc groove 61.

付勢部材３の付勢力によって第１の回転方向Ｄ１に回転する回転部材２および案内部５は、図５（Ａ）の状態から図４（Ａ）の状態となったときに、スライド部材Ｓの係合突起Ｓと、案内部５の案内溝５１の第２の端部５１ｂとが衝突する。この際、係合突起Ｓｂは、図９に示されるように、案内溝５１の第２の端部５１ｂと、円弧溝６１の側縁（第２の側縁Ｅ２）とに挟み込まれた状態となる。係合突起Ｓｂが案内部５の案内溝５１の第２の端部５１ｂと衝突して、回転部材２の回転方向（第１の回転方向Ｄ１）に力Ｆを受けるが、図１０に示されるように、スライド部材Ｓは曲げ部ＣＶを支点としてわずかに弾性変形する（図１０の二点鎖線参照）。これにより、係合突起Ｓｂが案内部５の案内溝５１の第２の端部５１ｂと衝突が吸収され、係合突起Ｓｂおよび係合突起Ｓｂの基部Ｓｂ１近傍の破損が抑制される。一方、図１１に示されるように、曲げ部ＣＶを有していないスライド部材Ｓ２の場合は、係合突起Ｓｂが案内部５の案内溝５１の第２の端部５１ｂと衝突して、回転部材２の回転方向（第１の回転方向Ｄ１）に力Ｆを受けた際に、衝撃を吸収することがほぼできない。そのため、スライド部材Ｓ２を繰り返し使用すると、係合突起Ｓｂの基端Ｓｂ１の近傍の領域Ｒ付近でスライド部材Ｓ２が折損していた。 The rotating member 2 and the guide portion 5 that rotate in the first rotation direction D1 due to the urging force of the urging member 3 move from the state of FIG. 5 (A) to the state of FIG. 4 (A), and the slide member S The engaging protrusion S of the guide portion 5 collides with the second end portion 51b of the guide groove 51 of the guide portion 5. At this time, as shown in FIG. 9, the engaging protrusion Sb is sandwiched between the second end portion 51b of the guide groove 51 and the side edge (second side edge E2) of the arc groove 61. Become. The engaging projection Sb collides with the second end portion 51b of the guide groove 51 of the guide portion 5 and receives a force F in the rotation direction (first rotation direction D1) of the rotating member 2, which is shown in FIG. As described above, the slide member S is slightly elastically deformed with the bent portion CV as a fulcrum (see the two-dot chain line in FIG. 10). As a result, the engagement projection Sb is absorbed from the second end portion 51b of the guide groove 51 of the guide portion 5, and the engagement projection Sb and the engagement projection Sb in the vicinity of the base portion Sb1 are suppressed from being damaged. On the other hand, as shown in FIG. 11, in the case of the slide member S2 having no bent portion CV, the engaging projection Sb collides with the second end portion 51b of the guide groove 51 of the guide portion 5 and rotates. When a force F is applied in the rotation direction of the member 2 (first rotation direction D1), it is almost impossible to absorb the impact. Therefore, when the slide member S2 is repeatedly used, the slide member S2 is broken in the vicinity of the region R near the base end Sb1 of the engaging projection Sb.

本実施形態では、スライド部材Ｓは、係合突起Ｓｂに加わった力が、係合突起Ｓｂ以外に曲げ部ＣＶに分散されるので、係合突起Ｓｂの基端Ｓｂ１の近傍に加わる力が小さくなり、スライド部材Ｓの破損が抑制される。また、本実施形態では、スライド部材Ｓが曲げ部ＣＶを有しているため、図４（Ａ）の状態から図５（Ａ）の状態までの間や、図５（Ａ）の状態から図６（Ａ）の状態までの間などにおいて、スライド部材Ｓに力が加わったときに、曲げ部ＣＶを支点としてスライド部材Ｓが弾性変形して、衝撃を吸収することもできる。 In the present embodiment, in the slide member S, the force applied to the engaging projection Sb is distributed to the bent portion CV other than the engaging projection Sb, so that the force applied to the vicinity of the base end Sb1 of the engaging projection Sb is small. Therefore, damage to the slide member S is suppressed. Further, in the present embodiment, since the slide member S has the bent portion CV, it is shown between the state of FIG. 4 (A) and the state of FIG. 5 (A) and the state of FIG. 5 (A). When a force is applied to the slide member S until the state of 6 (A) or the like, the slide member S is elastically deformed with the bent portion CV as a fulcrum to absorb the impact.

また、本実施形態では、連結部Ｓｃは、図１０に示されるように、係合突起Ｓｂの基端Ｓｂ１から、案内溝５１の第２の端部５１ｂから加わる、第１の回転方向Ｄ１に沿う力Ｆの方向に対して傾斜する方向（略垂直な方向）に延びている。この場合、案内溝５１の第２の端部５１ｂから加わる力Ｆが加わったときに、曲げ部ＣＶを支点として連結部Ｓｃが撓みやすく、よりスライド部材Ｓの破損を抑制することができる。 Further, in the present embodiment, as shown in FIG. 10, the connecting portion Sc joins from the base end Sb1 of the engaging projection Sb to the second end portion 51b of the guide groove 51 in the first rotation direction D1. It extends in a direction (substantially perpendicular to the direction) inclining with respect to the direction of the force F along the line. In this case, when the force F applied from the second end portion 51b of the guide groove 51 is applied, the connecting portion Sc is easily bent with the bent portion CV as a fulcrum, and damage to the slide member S can be further suppressed.

また、本実施形態では、図２、図３、図４（Ａ）、図９に示されるように、基部６の第２の面Ｆ２は、第２の面Ｆ２に対して略垂直な方向に突出する第１壁部Ｗ１を有している。第１壁部Ｗ１は、円弧溝６１の少なくとも一方の端部（本実施形態では、第２の円弧端部６１ｂ）の周縁（第２の側縁Ｅ２側）において、案内溝５１の終端（本実施形態では、第２の端部５１ｂ）から係合突起Ｓｂに対して力Ｆが加わったときに、係合突起Ｓｂと当接するように設けられている。基部６の第２の面Ｆ２において第１壁部Ｗ１が設けられていることにより、係合突起Ｓｂが円弧溝６１の内壁（第２の側縁Ｅ２）だけでなく、第１壁部Ｗ１にも当接して、係合突起Ｓｂに加わる力が分散される。したがって、係合突起Ｓｂの破損がさらに抑制される。なお、本実施形態では、第１壁部Ｗ１は、円弧溝６１の内壁となる第２の側縁Ｅ２と連続して同一面を形成するように設けられている。また、第１壁部Ｗ１の第２の面Ｆ２からの高さは、特に限定されない。また、第１壁部Ｗ１は、本実施形態では、円弧溝６１の第２の円弧端部６１ｂ側のみに設けられているが、第１の円弧端部６１ａ側に設けられていてもよい。 Further, in the present embodiment, as shown in FIGS. 2, 3, 4 (A), and 9, the second surface F2 of the base 6 is oriented substantially perpendicular to the second surface F2. It has a protruding first wall portion W1. The first wall portion W1 is the end of the guide groove 51 (main) at the peripheral edge (second side edge E2 side) of at least one end of the arc groove 61 (in this embodiment, the second arc end 61b). In the embodiment, it is provided so as to come into contact with the engaging protrusion Sb when a force F is applied to the engaging protrusion Sb from the second end portion 51b). Since the first wall portion W1 is provided on the second surface F2 of the base portion 6, the engaging projection Sb is formed not only on the inner wall (second side edge E2) of the arc groove 61 but also on the first wall portion W1. Also abuts, and the force applied to the engaging projection Sb is dispersed. Therefore, the breakage of the engaging protrusion Sb is further suppressed. In this embodiment, the first wall portion W1 is provided so as to form a continuous surface with the second side edge E2 which is the inner wall of the arc groove 61. Further, the height of the first wall portion W1 from the second surface F2 is not particularly limited. Further, in the present embodiment, the first wall portion W1 is provided only on the second arc end portion 61b side of the arc groove 61, but may be provided on the first arc end portion 61a side.

また、本実施形態では、図２、図３、図４（Ａ）、図９に示されるように、基部６の第２の面Ｆ２が、第２の面Ｆ２に対して略垂直な方向に突出する第２壁部Ｗ２を有している。第２壁部Ｗ２は、円弧溝６１の少なくとも一方の端部（本実施形態では、第２の円弧端部６１ｂ）の周縁（第１の側縁Ｅ１側）において、円弧溝６１を挟んで第１壁部Ｗ１に対向して設けられている。この場合、スライド部材Ｓの係合突起Ｓｂの位置が、第１壁部Ｗ１と第２壁部Ｗ２とに挟まれることにより、安定しやすい。そのため、係合突起Ｓｂが案内溝５１および円弧溝６１から抜ける方向に移動することが抑制される。 Further, in the present embodiment, as shown in FIGS. 2, 3, 4 (A), and 9, the second surface F2 of the base 6 is oriented substantially perpendicular to the second surface F2. It has a protruding second wall portion W2. The second wall portion W2 sandwiches the arc groove 61 at the peripheral edge (first side edge E1 side) of at least one end of the arc groove 61 (in this embodiment, the second arc end 61b). 1 It is provided so as to face the wall portion W1. In this case, the position of the engaging protrusion Sb of the slide member S is easily stabilized by being sandwiched between the first wall portion W1 and the second wall portion W2. Therefore, the engagement protrusion Sb is suppressed from moving in the direction of exiting from the guide groove 51 and the arc groove 61.
