Abstract

An actuator is provided with a case, a stopper which is provided to the case so as to extend in the protrusion direction, a worm wheel which is provided to the case, an engagement protrusion which protrudes from the worm wheel, and a torsion coil spring which is housed within the worm wheel. The engagement protrusion makes contact with the stopper to restrict the worm wheel to a predetermined initial position. The torsion coil spring has a first leg which is engaged with the stopper and a second leg which is engaged with the engagement protrusion at a position further toward the outside in the protrusion direction than the stopper. The torsion coil spring presses the worm wheel in the direction in which the engagement protrusion makes contact with the stopper.

Description

アクチュエータActuator
　本発明は、アクチュエータに関するものである。 The present invention relates to an actuator.
　従来、アクチュエータとして種々のものが提案されている。例えば特許文献１は、車両の施解錠に係るロック装置に適用されるアクチュエータを開示する。該アクチュエータにおいて、その筐体をなすケースには、電動モータにより回転される出力部材が収容されている。また、ケースの底面には、半円筒状のばね取付用壁が突出するように設けられている。出力部材の底面には、半円筒状の係合片が突出するように設けられている。係合片は、ばね取付用壁の径方向内側に配置されている。ケースには、復帰ばねが収容されている。復帰ばねの両脚部、即ち両端は、ばね取付用壁および係合片に係止可能である。電動モータの駆動力から解放された出力部材は、復帰ばねにより所定の中立位置に復帰するように周方向に付勢されている。中立位置では、復帰ばねの両脚部が共にばね取付用壁及び係合片に係止される。一方、出力部材は、電動モータの駆動力により復帰ばねの付勢力に抗して正逆回転することで、当該回転方向に応じて選択的に施錠状態及び解錠状態に切り替える。 Conventionally, various actuators have been proposed. For example, Patent Literature 1 discloses an actuator that is applied to a locking device related to locking and unlocking of a vehicle. In the actuator, an output member that is rotated by an electric motor is accommodated in a case that forms the casing. A semi-cylindrical spring mounting wall is provided on the bottom surface of the case so as to protrude. A semi-cylindrical engagement piece is provided on the bottom surface of the output member so as to protrude. The engaging piece is disposed on the radially inner side of the spring mounting wall. A return spring is accommodated in the case. Both leg portions, i.e., both ends of the return spring can be locked to the spring mounting wall and the engaging piece. The output member released from the driving force of the electric motor is urged in the circumferential direction so as to return to a predetermined neutral position by a return spring. In the neutral position, both legs of the return spring are locked to the spring mounting wall and the engaging piece. On the other hand, the output member rotates in the forward and reverse directions against the biasing force of the return spring by the driving force of the electric motor, thereby selectively switching between the locked state and the unlocked state according to the rotation direction.
　また、特許文献２は、車両ドアを閉状態で保持可能なラッチ機構の解除に係るリリース装置に適用されるアクチュエータを開示する。このアクチュエータの筐体をなすケースにも、電動モータにより回転される出力部材が収容されている。また、ケースには、該ケース及び出力部材に両脚部がそれぞれ係止された復帰ばねが収容されている。そして、電動モータの駆動力から解放された出力部材は、復帰ばねにより所定の初期位置に復帰するように周方向に付勢されている。一方、出力部材は、電動モータの駆動力により復帰ばねの付勢力に抗して所定方向に回転することでラッチ機構を解除する。特許文献２のアクチュエータは、特許文献１のアクチュエータのように、所定の中立位置からの正逆回転によって動作を切り替える構成を採用していないため、自ずとアクチュエータの機械的・電気的構成が簡素化されている。 Further, Patent Document 2 discloses an actuator applied to a release device related to release of a latch mechanism that can hold a vehicle door in a closed state. An output member that is rotated by an electric motor is also housed in the case that forms the housing of the actuator. The case also houses a return spring in which both leg portions are locked to the case and the output member. The output member released from the driving force of the electric motor is urged in the circumferential direction so as to return to a predetermined initial position by a return spring. On the other hand, the output member releases the latch mechanism by rotating in a predetermined direction against the biasing force of the return spring by the driving force of the electric motor. Since the actuator of Patent Document 2 does not employ a configuration in which the operation is switched by forward and reverse rotation from a predetermined neutral position, unlike the actuator of Patent Document 1, the mechanical and electrical configuration of the actuator is naturally simplified. ing.

　ところで、特許文献２のアクチュエータでは、出力部材の所定の初期位置は、復帰ばねに付加される外力や振動等の影響を受けて変動するため、初期位置の精度にばらつきが生じる可能性がある。そこで、ケース及び出力部材にそれぞれストッパ及び係合突部を配設し、これらストッパ及び係合突部が当接する出力部材の回動位置を所定の初期位置として、復帰ばねにより復帰させることも提案されている。 By the way, in the actuator of Patent Document 2, the predetermined initial position of the output member fluctuates due to the influence of external force or vibration applied to the return spring, so that the accuracy of the initial position may vary. Therefore, it is also proposed to arrange a stopper and an engaging protrusion on the case and the output member, respectively, and to return the rotating position of the output member that contacts the stopper and the engaging protrusion to a predetermined initial position by a return spring. Has been.
　このように復帰ばねを介在させてケースに出力部材を組み付ける場合には、例えば次のような手順で行われる。まず、ケースの適宜位置に復帰ばねの一方の脚部である第１脚部を係止した状態で、復帰ばねの弾性復帰状態（自由状態）のままその他方の脚部である第２脚部が出力部材の適宜位置に係止される。このとき、このような仮組み状態のまま復帰ばねの付勢力に抗してストッパ及び係合突部が当接するまで出力部材を回転させる必要がある。この場合、不安定な仮組み状態で出力部材を初期位置へと回転させることになり、例えば組付作業時に復帰ばねの脚部（第１又は第２脚部）がケース又は出力部材から外れる可能性がある。 When the output member is assembled to the case with the return spring interposed as described above, for example, the following procedure is performed. First, with the first leg, which is one leg of the return spring, locked at an appropriate position of the case, the second leg, which is the other leg, remains in the elastic return state (free state) of the return spring. Is locked at an appropriate position of the output member. At this time, it is necessary to rotate the output member until the stopper and the engaging protrusion come into contact with each other in the temporarily assembled state against the urging force of the return spring. In this case, the output member is rotated to the initial position in an unstable temporary assembled state, and for example, the leg portion (first or second leg portion) of the return spring can be detached from the case or the output member during the assembly work. There is sex.
　従って、出力部材等の部材の組付作業を容易にするためには、これら部材の部品精度を著しく高く設定する一方で、各部材間に所要の間隙を設定する必要がある。また、ケースに収容されている復帰ばね等の部材に出力部材を組み付けることになるため、該出力部材に邪魔されて目視での組付作業が困難になり、部材間の位置合わせが困難になってしまう。 Therefore, in order to facilitate the assembly work of the members such as the output member, it is necessary to set a required gap between the members while setting the parts accuracy of these members extremely high. Further, since the output member is assembled to a member such as a return spring housed in the case, it is obstructed by the output member, making it difficult to assemble visually, and positioning between the members becomes difficult. End up.
　本発明の目的は、精度を損ねることなく組付性を向上することができるアクチュエータを提供することにある。 An object of the present invention is to provide an actuator capable of improving the assembling property without impairing accuracy.
　上記問題点を解決するために、本発明の一態様は、ケースと、該ケースに回動自在に収容され電動モータにより回転される出力部材と、前記ケースに突出方向へ延びるように設けられたストッパと、前記出力部材から突出し、前記ストッパに当接することにより前記出力部材を所定の初期位置に規制する係合突部と、前記ケースに収容されたトーションコイルスプリングとを備え、前記トーションコイルスプリングは、一端に設けられ前記ケースに係止された第１脚部と、他端に設けられ前記ストッパよりも該ストッパの突出方向の外側で前記係合突部に係止された第２脚部とを有し、前記トーションコイルスプリングは、該係合突部が前記ストッパに当接する方向に向かって前記出力部材を付勢するアクチュエータを提供する。 In order to solve the above-described problems, one embodiment of the present invention is provided with a case, an output member that is rotatably accommodated in the case and rotated by an electric motor, and extends in the protruding direction in the case. A torsion coil spring, comprising: a stopper; an engaging protrusion that protrudes from the output member and contacts the stopper to restrict the output member to a predetermined initial position; and a torsion coil spring housed in the case The first leg portion provided at one end and locked to the case, and the second leg portion provided at the other end and locked to the engagement protrusion outside the stopper in the protruding direction of the stopper And the torsion coil spring provides an actuator that urges the output member in a direction in which the engagement protrusion comes into contact with the stopper.
　同構成によれば、トーションコイルスプリングの両脚部（第１及び第２脚部）がそれぞれ前記ケース及び前記係合突部に係止される。前記電動モータの駆動力から解放された前記出力部材は、前記トーションコイルスプリングにより該係合突部が前記ストッパに当接する方向に向かって、即ち前記所定の初期位置に復帰するように周方向に付勢されている。一方、前記出力部材は、前記電動モータの駆動力により前記トーションコイルスプリングの付勢力に抗して前記係合突部が前記ストッパから離隔する所定方向に回動することで、所要の動作を行う。 According to this configuration, both legs (first and second legs) of the torsion coil spring are locked to the case and the engaging protrusion, respectively. The output member released from the driving force of the electric motor is moved in the circumferential direction so that the engagement protrusion is brought into contact with the stopper by the torsion coil spring, that is, returned to the predetermined initial position. It is energized. On the other hand, the output member performs a required operation by rotating in a predetermined direction in which the engaging protrusion is separated from the stopper against the biasing force of the torsion coil spring by the driving force of the electric motor. .
　ここで、前記係合突部は、前記出力部材を前記所定の初期位置に規制するために前記ストッパに当接させる部位である。また、係合突部は、前記トーションコイルスプリングの前記第２脚部を係止するための部位でもある。従って、前記出力部材は、前記トーションコイルスプリングを介在させた状態で前記ケースに組み付けられる。この場合、まず、前記トーションコイルスプリングの前記第１脚部を前記ケースに係止させた状態で前記トーションコイルスプリングが前記ケースに仮組みされる。このとき、前記トーションコイルスプリングは、弾性復帰状態（自由状態）で前記ケースに収容されており、前記第２脚部は、前記ストッパよりも該ストッパの突出方向の外側に配置されている。続いて、例えば前記ストッパから外側への前記第２脚部の突出している部分の係合代で該第２脚部が前記係合突部に係止される。前記係合突部が前記ストッパを乗り越える回動位置、即ち所定の初期位置に相当する回動位置まで、前記トーションコイルスプリングの付勢力に抗して前記出力部材が回動される。そして、この状態で、前記出力部材を前記ケースに向かって軸方向に沿って移動させると、前記第２脚部及び前記係合突部の係合代を増加しつつ該係合突部が周方向で前記ストッパに当接する。そして、前記出力部材は、前記トーションコイルスプリングを介在させた状態で前記所定の初期位置に配置され、前記ケースへの前記出力部材の組付けが完了する。このように、前記出力部材の前記ケースへの組付けを円滑に行うことができる。 Here, the engagement protrusion is a portion that is brought into contact with the stopper in order to restrict the output member to the predetermined initial position. The engaging protrusion is also a part for locking the second leg of the torsion coil spring. Therefore, the output member is assembled to the case with the torsion coil spring interposed. In this case, first, the torsion coil spring is temporarily assembled to the case in a state where the first leg portion of the torsion coil spring is locked to the case. At this time, the torsion coil spring is accommodated in the case in an elastic return state (free state), and the second leg portion is disposed outside the stopper in the protruding direction of the stopper. Subsequently, for example, the second leg portion is locked to the engagement protrusion by the engagement margin of the protruding portion of the second leg portion outward from the stopper. The output member is rotated against the urging force of the torsion coil spring to a rotation position where the engagement protrusion gets over the stopper, that is, a rotation position corresponding to a predetermined initial position. Then, in this state, when the output member is moved along the axial direction toward the case, the engagement protrusion is rotated while increasing the engagement allowance of the second leg portion and the engagement protrusion. Abuts against the stopper in a direction. The output member is arranged at the predetermined initial position with the torsion coil spring interposed, and the assembly of the output member to the case is completed. Thus, the output member can be smoothly assembled to the case.

　図１～図５（ｃ）を参照して本発明の一実施形態に係るアクチュエータについて説明する。図１に示すように、アクチュエータは、自動車などの車両ドア（図示略）に搭載されるリリース装置に適用される。アクチュエータは、その筐体をなす箱状のケース１１を備える。ケース１１は樹脂材からなる。ケース１１には、図示右側で電動モータ１２が収容されている。この電動モータ１２の回転軸１２ａは、図示横方向に沿って延び、ケース１１の中央部で該ケース１１に回転可能に支持されている。回転軸１２ａにはウォーム１３が固着されている。 An actuator according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5 (c). As shown in FIG. 1, the actuator is applied to a release device mounted on a vehicle door (not shown) such as an automobile. The actuator includes a box-shaped case 11 that forms the casing. The case 11 is made of a resin material. The case 11 houses an electric motor 12 on the right side of the figure. A rotating shaft 12 a of the electric motor 12 extends along the horizontal direction in the figure, and is rotatably supported by the case 11 at the center of the case 11. A worm 13 is fixed to the rotary shaft 12a.
　ケース１１には、底面から支持部１４が突出するように設けられている。支持部１４は、ウォーム１３の図示上側に配置されている。図５（ａ）に示すように、この支持部１４は、段付き円筒形状を呈している。即ち、支持部１４は、基端側に位置する大径部と、環状の段差１４ａを介して先端側に位置する小径の先端部１４ｂとを有する。図１に示すように、支持部１４には、段差１４ａに載置される態様でその先端部１４ｂにウォームホイール１５が回転自在に支持されている。すなわち、ウォームホイール１５は、その中心部に円筒状の軸部１５ａを有している。ウォームホイール１５の軸部１５ａに支持部１４の先端部１４ｂが挿入されることで、ウォームホイール１５は支持部１４に回転自在に支持されている。このウォームホイール１５は、ウォーム１３と噛合しており、該ウォーム１３（回転軸１２ａ）の回転に連動して支持部１４の軸心周りに回転する。ウォームホイール１５は、ウォーム１３と共にウォームギヤを構成する。なお、ウォームホイール１５には、軸部１５ａから図示反時計回転方向に向かうに従い、径方向外側に向かう略渦巻き状のカム部１５ｂが形成されている。 The case 11 is provided with a support portion 14 protruding from the bottom surface. The support portion 14 is disposed on the upper side of the worm 13 in the figure. As shown in FIG. 5A, the support portion 14 has a stepped cylindrical shape. That is, the support portion 14 has a large diameter portion located on the proximal end side and a small diameter distal end portion 14b located on the distal end side via the annular step 14a. As shown in FIG. 1, the worm wheel 15 is rotatably supported by the support part 14 at the front-end | tip part 14b in the aspect mounted in the level | step difference 14a. That is, the worm wheel 15 has a cylindrical shaft portion 15a at the center thereof. The worm wheel 15 is rotatably supported by the support portion 14 by inserting the tip portion 14b of the support portion 14 into the shaft portion 15a of the worm wheel 15. The worm wheel 15 meshes with the worm 13 and rotates around the axis of the support portion 14 in conjunction with the rotation of the worm 13 (rotating shaft 12a). The worm wheel 15 constitutes a worm gear together with the worm 13. The worm wheel 15 is formed with a substantially spiral cam portion 15b that goes radially outward from the shaft portion 15a in the counterclockwise direction shown in the drawing.
　また、ケース１１には、図２に示すように、支持部１４の外周側となる図示下側でストッパ３１が底面から突出するように設けられている。ストッパ３１は、支持部１４と同心状の部分円筒状であり、即ち円弧状の周壁を有する。ストッパ３１の突出方向における先端側には第１端面３１ｃが形成されている。第１端面３１ｃは、支持部１４の中心、即ちウォームホイール１５の回転軸心を中心とした円弧形状である。一方、ウォームホイール１５の底面には、略扁平円柱状の係合突部３２が突出するように設けられている。係合突部３２は、ウォームホイール１５の底面からケース１１の底面に向かう方向、即ち図２において紙面に直交する奥側に向かって延びている。係合突部３２の突出方向における先端側には、第２端面３２ａ（図５（ｂ）参照）が形成されている。第２端面３２ａは、略扁平円形状である。ストッパ３１は、支持部１４の軸心周りのウォームホイール１５の回転に際し、係合突部３２の回動軌跡を遮る位置に配置されている。従って、支持部１４の軸心周りのウォームホイール１５の回動範囲は、係合突部３２がストッパ３１の図示左側の端面３１ａに当接する所定の回動位置（以下、「初期位置Ｐｓ」ともいう）から、図４に示すように、係合突部３２がストッパ３１の図示右側（反対側）の端面３１ｂに当接する所定の回動位置（以下、「最大回動位置Ｐｍ」ともいう）までの範囲内に規制されている。 Further, as shown in FIG. 2, the case 11 is provided with a stopper 31 protruding from the bottom surface on the lower side in the drawing, which is the outer peripheral side of the support portion 14. The stopper 31 has a partial cylindrical shape concentric with the support portion 14, that is, has an arc-shaped peripheral wall. A first end surface 31 c is formed on the tip end side in the protruding direction of the stopper 31. The first end face 31 c has an arc shape centered on the center of the support portion 14, that is, the rotation axis of the worm wheel 15. On the other hand, a substantially flat cylindrical engagement protrusion 32 is provided on the bottom surface of the worm wheel 15 so as to protrude. The engagement protrusion 32 extends from the bottom surface of the worm wheel 15 toward the bottom surface of the case 11, that is, toward the back side orthogonal to the paper surface in FIG. 2. A second end face 32a (see FIG. 5B) is formed on the distal end side of the engaging protrusion 32 in the protruding direction. The second end surface 32a has a substantially flat circular shape. The stopper 31 is disposed at a position where the rotation locus of the engaging protrusion 32 is blocked when the worm wheel 15 rotates around the axis of the support portion 14. Therefore, the rotation range of the worm wheel 15 around the axis of the support portion 14 is a predetermined rotation position (hereinafter referred to as “initial position Ps”) where the engagement protrusion 32 abuts the left end surface 31a of the stopper 31 in the drawing. Therefore, as shown in FIG. 4, a predetermined rotation position (hereinafter also referred to as “maximum rotation position Pm”) at which the engagement protrusion 32 abuts on the right end (opposite side) end surface 31b of the stopper 31 as shown in FIG. It is regulated within the range.
　さらに、ケース１１には、ストッパ３１の径方向内側となる支持部１４の軸心周りに、トーションコイルスプリング３３が収容されている。図５（ａ）～（ｃ）に示すように、このトーションコイルスプリング３３は、支持部１４の基端側から先端側に向かって時計回転方向に巻回された、該支持部１４と略同心のコイル部３３ａを有する。また、トーションコイルスプリング３３は、該コイル部３３ａに繋がる支持部１４の基端を折り返して形成された第１脚部３３ｂを有し、更にコイル部３３ａに繋がる支持部１４の先端を折り返してなる第２脚部３３ｃを有する。なお、コイル部３３ａの先端は、ストッパ３１よりも該ストッパ３１の突出方向、即ち支持部１４の軸線方向の外側に配置されている。従って、第２脚部３３ｃも、ストッパ３１よりも該ストッパ３１の突出方向の外側に配置されている。即ち、第２脚部３３ｃは、ストッパ３１の上端３１ｃよりも上方に配置されている。 Furthermore, a torsion coil spring 33 is accommodated in the case 11 around the axis of the support portion 14 which is the radially inner side of the stopper 31. As shown in FIGS. 5A to 5C, the torsion coil spring 33 is substantially concentric with the support portion 14 wound in the clockwise direction from the proximal end side to the distal end side of the support portion 14. Coil part 33a. The torsion coil spring 33 has a first leg portion 33b formed by folding back the base end of the support portion 14 connected to the coil portion 33a, and further, the tip end of the support portion 14 connected to the coil portion 33a is folded back. It has the 2nd leg part 33c. Note that the tip of the coil portion 33 a is disposed more outwardly than the stopper 31 in the protruding direction of the stopper 31, that is, in the axial direction of the support portion 14. Accordingly, the second leg portion 33 c is also arranged outside the stopper 31 in the protruding direction of the stopper 31. That is, the second leg portion 33 c is disposed above the upper end 31 c of the stopper 31.
　そして、第１脚部３３ｂは、ストッパ３１の端面３１ｂに係止されている。これに対して、第２脚部３３ｃは、トーションコイルスプリング３３の弾性復帰状態（自由状態）では端面３１ｂ近傍に配置される。第２脚部３３ｃは、該端面３１ｂから端面３１ａ近傍までトーションコイルスプリング３３の付勢力に抗して図示時計回転方向に回動した状態ではウォームホイール１５の係合突部３２に係止されている。これにより、ウォームホイール１５は、係合突部３２がストッパ３１の端面３１ａに当接するように向かう方向である図示反時計回転方向、即ち初期位置Ｐｓに向かって付勢されている。これに対して、ウォームホイール１５は、トーションコイルスプリング３３の付勢力に抗して図示時計回転方向に回転することで、係合突部３２がストッパ３１の端面３１ｂに当接する最大回動位置Ｐｍへと移動する。 The first leg 33b is locked to the end surface 31b of the stopper 31. On the other hand, the second leg portion 33c is disposed in the vicinity of the end face 31b in the elastic return state (free state) of the torsion coil spring 33. The second leg portion 33c is locked to the engaging protrusion 32 of the worm wheel 15 in a state where the second leg portion 33c is rotated in the clockwise direction in the figure against the urging force of the torsion coil spring 33 from the end surface 31b to the vicinity of the end surface 31a. Yes. As a result, the worm wheel 15 is biased toward the illustrated counterclockwise rotation direction, that is, the direction in which the engagement protrusion 32 is in contact with the end surface 31 a of the stopper 31, that is, the initial position Ps. On the other hand, the worm wheel 15 rotates in the clockwise direction shown in the figure against the urging force of the torsion coil spring 33, so that the maximum rotation position Pm at which the engagement protrusion 32 abuts on the end surface 31b of the stopper 31. Move to.
　つまり、係合突部３２は、ウォームホイール１５を初期位置Ｐｓ又は最大回動位置Ｐｍに規制するためにウォームホイール１５をストッパ３１に当接させる部位である。また、係合突部３２は、トーションコイルスプリング３３の第２脚部３３ｃを係止させるための部位でもある。なお、トーションコイルスプリング３３の第２脚部３３ｃは、ストッパ３１よりも該ストッパ３１の突出方向の外側で係合突部３２に係止されているため、初期位置Ｐｓ及び最大回動位置Ｐｍのいずれにおいてもウォームホイール１５の係合突部３２とストッパ３１との間に挟まれることはない。 That is, the engagement protrusion 32 is a part that makes the worm wheel 15 contact the stopper 31 in order to restrict the worm wheel 15 to the initial position Ps or the maximum rotation position Pm. Further, the engaging protrusion 32 is also a part for locking the second leg portion 33 c of the torsion coil spring 33. Since the second leg 33c of the torsion coil spring 33 is locked to the engaging protrusion 32 outside the stopper 31 in the protruding direction of the stopper 31, the initial position Ps and the maximum rotation position Pm are set. In either case, the worm wheel 15 is not sandwiched between the engaging protrusion 32 and the stopper 31.
　図１に示すように、ケース１１には、回転軸１２ａの図示左側で底面から段付き円筒形状の支持部１６が突出するように設けられている。該支持部１６には、略Ｔ字状のリリースレバー１７が回転自在に支持されている。このリリースレバー１７は、支持部１６からウォームホイール１５に向かう径方向に延出して軸部１５ａおよびカム部１５ｂの外面に接触可能な入力アーム１７ａを有する。また、リリースレバー１７は、支持部１６から図示下方に向かう径方向に延出する出力アーム１７ｂを有する。出力アーム１７ｂの先端部は、ケース１１の外側に露出している。そして、図１に示すように、ウォームホイール１５が初期位置Ｐｓにあるとき、入力アーム１７ａは軸部１５ａの外面に接している。また、例えばウォームホイール１５が初期位置Ｐｓからトーションコイルスプリング３３の付勢力に抗して図示時計回転方向に回転すると、入力アーム１７ａがカム部１５ｂに案内される。これにより、リリースレバー１７は、図示時計回転方向に回動する。そして、図３に示すように、ウォームホイール１５が最大回動位置Ｐｍに達するまで、リリースレバー１７は、ウォームホイール１５の回転に連動して図示時計回転方向に回動する。 As shown in FIG. 1, the case 11 is provided with a stepped cylindrical support 16 protruding from the bottom surface on the left side of the rotating shaft 12a in the drawing. A substantially T-shaped release lever 17 is rotatably supported by the support portion 16. The release lever 17 has an input arm 17a that extends in the radial direction from the support portion 16 toward the worm wheel 15 and can contact the outer surface of the shaft portion 15a and the cam portion 15b. The release lever 17 has an output arm 17b extending from the support portion 16 in the radial direction downward in the figure. The tip end of the output arm 17b is exposed to the outside of the case 11. As shown in FIG. 1, when the worm wheel 15 is at the initial position Ps, the input arm 17a is in contact with the outer surface of the shaft portion 15a. For example, when the worm wheel 15 rotates in the clockwise direction shown in the figure against the biasing force of the torsion coil spring 33 from the initial position Ps, the input arm 17a is guided to the cam portion 15b. Thereby, the release lever 17 rotates in the illustrated clockwise rotation direction. Then, as shown in FIG. 3, the release lever 17 rotates in the illustrated clockwise direction in conjunction with the rotation of the worm wheel 15 until the worm wheel 15 reaches the maximum rotation position Pm.
　車両ドアには、図１に示すように、適宜のブラケットを介してラッチ機構２１が設置されている。このラッチ機構２１は、互いに平行な軸心周りにブラケットに回動自在にそれぞれ連結されたラッチ２２及びポール(pawl)２３を備えている。ラッチ機構２１は、車両ボディ（図示略）に固着されたストライカ２０と係脱可能となっている。すなわち、車両ドアを閉操作する際にストライカ２０に押圧されるラッチ２２が回動してストライカ２０と係合し、同時にポール２３がラッチ２２を回り止めすることで車両ドアを閉状態で保持する。また、図３に示すように、電動モータ１２の駆動力でウォームホイール１５を回転させることにより、これに連動するリリースレバー１７の出力アーム１７ｂでポール２３のフランジ状の係合片２３ａを押圧すると、ポール２３が回動してラッチ２２の回り止めを解除する。これにより、ラッチ２２はラッチ復帰スプリング（図示略）に付勢されて解除位置へ戻るように回動し、ストライカ２０との係合状態を解除して車両ドアを開可能状態にする。このとき、ラッチ２２は、車両ドアの閉操作時にストライカ２０と係合可能な姿勢となっている。なお、電動モータ１２の駆動力から解放されると、ウォームホイール１５は、トーションコイルスプリング３３に付勢されて初期位置Ｐｓまで戻るように回動する。これに伴い、係合片２３ａにおけるリリースレバー１７の押圧力から解放されるポール２３は、ポール復帰スプリング（図示略）に付勢されて図１に示す位置まで戻るように回動する。ポール２３の戻り回動に伴い係合片２３ａによって出力アーム１７ｂが押圧される。これにより、カム部１５ｂに入力アーム１７ａが係合されるリリースレバー１７は、図１に示す位置まで戻るように回動する。 As shown in FIG. 1, a latch mechanism 21 is installed on the vehicle door via an appropriate bracket. The latch mechanism 21 includes a latch 22 and a pawl 23 that are rotatably connected to a bracket around axes parallel to each other. The latch mechanism 21 can be engaged with and disengaged from the striker 20 fixed to the vehicle body (not shown). That is, when the vehicle door is closed, the latch 22 pressed by the striker 20 rotates and engages with the striker 20, and at the same time, the pawl 23 prevents the latch 22 from rotating, thereby holding the vehicle door in a closed state. . Further, as shown in FIG. 3, when the worm wheel 15 is rotated by the driving force of the electric motor 12, the flange-like engagement piece 23a of the pole 23 is pressed by the output arm 17b of the release lever 17 interlocked therewith. The pole 23 rotates to release the latch 22 from rotating. As a result, the latch 22 is urged by a latch return spring (not shown) and rotates so as to return to the release position, and the engagement state with the striker 20 is released to make the vehicle door openable. At this time, the latch 22 is in a posture capable of engaging with the striker 20 when the vehicle door is closed. When released from the driving force of the electric motor 12, the worm wheel 15 is urged by the torsion coil spring 33 to rotate back to the initial position Ps. Along with this, the pole 23 released from the pressing force of the release lever 17 in the engagement piece 23a is urged by a pole return spring (not shown) and rotates so as to return to the position shown in FIG. As the pole 23 returns and rotates, the output arm 17b is pressed by the engagement piece 23a. Thereby, the release lever 17 with which the input arm 17a is engaged with the cam portion 15b rotates so as to return to the position shown in FIG.
　次に、本実施形態の組付態様について説明する。 Next, the assembly mode of this embodiment will be described.
　図５（ａ）に示すように、まず、ケース１１の支持部１４の軸心周りとなるストッパ３１の径方向内側で、弾性復帰状態（自由状態）にあるトーションコイルスプリング３３のコイル部３３ａが支持部１４と同軸上に配置され、ケース１１内に収容される。第１脚部３３ｂがストッパ３１の端面３１ｂに係止される。このとき、トーションコイルスプリング３３のコイル部３３ａの先端は、ストッパ３１よりも該ストッパ３１の突出方向の外側に配置されている。第２脚部３３ｃは、ストッパ３１の端面３１ｂ近傍でストッパ３１よりも該ストッパ３１の突出方向の外側に配置されている。 As shown in FIG. 5A, first, the coil portion 33a of the torsion coil spring 33 in the elastic return state (free state) is radially inward of the stopper 31 around the axis of the support portion 14 of the case 11. It is disposed coaxially with the support portion 14 and is accommodated in the case 11. The first leg 33 b is locked to the end surface 31 b of the stopper 31. At this time, the tip of the coil portion 33 a of the torsion coil spring 33 is disposed outside the stopper 31 in the protruding direction of the stopper 31. The second leg portion 33 c is disposed near the end surface 31 b of the stopper 31 and on the outer side of the stopper 31 in the protruding direction of the stopper 31.
　続いて、図５（ｂ）に示すように、ケース１１の先端部１４ｂにウォームホイール１５の軸部１５ａを挿入しつつ、ストッパ３１から外側への第２脚部３３ｃの突出した部分の係合代で該第２脚部３３ｃにウォームホイール１５の係合突部３２が概ね係止される。このとき、係合突部３２の第２端面３２ａは、ストッパ３１の第１端面３１ｃに当接する。 Subsequently, as shown in FIG. 5 (b), the shaft portion 15a of the worm wheel 15 is inserted into the tip portion 14b of the case 11, and the protruding portion of the second leg portion 33c outward from the stopper 31 is engaged. Instead, the engaging protrusion 32 of the worm wheel 15 is generally locked to the second leg 33c. At this time, the second end surface 32 a of the engagement protrusion 32 abuts on the first end surface 31 c of the stopper 31.
　この状態で、トーションコイルスプリング３３の付勢力に抗してウォームホイール１５が先端部１４ｂの軸心周りに図示時計回転方向に回動される。このとき、ストッパ３１の第１端面３１ｃは、係合突部３２の第２端面３２ａと当接することによりウォームホイール１５の組み付けを案内する。係合突部３２は、ストッパ３１上、即ち第１端面３１ｃ上を摺動する。そして、係合突部３２がストッパ３１を乗り越える位置、即ち初期位置Ｐｓに相当する位置までウォームホイール１５が回動すると、ウォームホイール１５が支持部１４の基端に向かって軸方向に移動される。そして、該ウォームホイール１５の軸部１５ａをケース１１の先端部１４ｂに更に挿入することにより、ウォームホイール１５が段差１４ａに載置される。このとき、図５（ｃ）に示すように、第２脚部３３ｃ及び係合突部３２の係合代を増加させる態様で該係合突部３２が周方向でストッパ３１の端面３１ａに当接する。そして、ウォームホイール１５は、トーションコイルスプリング３３を介在させた状態で初期位置Ｐｓに配置され、ケース１１に対するウォームホイール１５の組付けが完了する。 In this state, the worm wheel 15 is rotated around the axis of the tip end portion 14b in the clockwise direction in the figure against the urging force of the torsion coil spring 33. At this time, the first end surface 31 c of the stopper 31 abuts on the second end surface 32 a of the engaging protrusion 32 to guide the assembly of the worm wheel 15. The engaging protrusion 32 slides on the stopper 31, that is, on the first end surface 31 c. Then, when the worm wheel 15 rotates to a position where the engaging protrusion 32 gets over the stopper 31, that is, a position corresponding to the initial position Ps, the worm wheel 15 is moved in the axial direction toward the base end of the support portion 14. . Then, by further inserting the shaft portion 15a of the worm wheel 15 into the tip portion 14b of the case 11, the worm wheel 15 is placed on the step 14a. At this time, as shown in FIG. 5 (c), the engagement protrusion 32 abuts against the end surface 31a of the stopper 31 in the circumferential direction in such a manner that the engagement margin between the second leg portion 33c and the engagement protrusion 32 is increased. Touch. The worm wheel 15 is disposed at the initial position Ps with the torsion coil spring 33 interposed, and the assembly of the worm wheel 15 to the case 11 is completed.
　次に、本実施形態の動作について説明する。 Next, the operation of this embodiment will be described.
　まず、図１に示すように、ストライカ２０及びラッチ機構２１が互いに係合して車両ドアが閉状態で保持されており、電動モータ１２の駆動力から解放されているウォームホイール１５が初期位置Ｐｓに配置されているものとする。この状態で、電動モータ１２によってウォーム１３が回転されると、ウォームホイール１５がトーションコイルスプリング３３の付勢力に抗して図示時計回転方向に回転する。ウォームホイール１５の回転に連動してリリースレバー１７が図示時計回転方向に回動すると、図３に示すように、出力アーム１７ｂがポール２３の係合片２３ａを押圧する。これにより、ポール２３が回動してラッチ２２の回り止めが解除される。そして、ラッチ２２はラッチ復帰スプリング（図示略）によって付勢されて解除位置に戻るように回動し、ストライカ２０との係合状態を解除して車両ドアを開可能状態にする。このとき、ウォームホイール１５は、係合突部３２がストッパ３１の端面３１ｂに当接することでその回転が規制される。そのため、ウォームホイール１５は、最大回動位置Ｐｍに配置される。 First, as shown in FIG. 1, the striker 20 and the latch mechanism 21 are engaged with each other, the vehicle door is held in a closed state, and the worm wheel 15 released from the driving force of the electric motor 12 is moved to the initial position Ps. It shall be arranged in. When the worm 13 is rotated by the electric motor 12 in this state, the worm wheel 15 rotates in the clockwise direction in the figure against the urging force of the torsion coil spring 33. When the release lever 17 rotates in the clockwise direction in the figure in conjunction with the rotation of the worm wheel 15, the output arm 17b presses the engagement piece 23a of the pole 23 as shown in FIG. As a result, the pole 23 is rotated to release the latch 22 from being rotated. Then, the latch 22 is urged by a latch return spring (not shown) and rotates so as to return to the release position, and the engagement state with the striker 20 is released to make the vehicle door openable. At this time, the rotation of the worm wheel 15 is restricted by the engagement protrusion 32 coming into contact with the end surface 31 b of the stopper 31. Therefore, the worm wheel 15 is disposed at the maximum rotation position Pm.
　その後、電動モータ１２の駆動力から解放されると、ウォームホイール１５は、トーションコイルスプリング３３に付勢されて図示反時計回転方向に戻るように回転する。このとき、ウォームホイール１５は、係合突部３２がストッパ３１の端面３１ａに当接することでその回転が規制される。そのため、ウォームホイール１５は、初期位置Ｐｓに配置される。これに伴い、リリースレバー１７の押圧力から解放されるポール２３は、ポール復帰スプリング（図示略）に付勢されて図１に示す回動位置まで戻るように回動する。 Thereafter, when released from the driving force of the electric motor 12, the worm wheel 15 is urged by the torsion coil spring 33 and rotates so as to return in the counterclockwise direction shown in the drawing. At this time, the rotation of the worm wheel 15 is restricted by the engagement protrusion 32 coming into contact with the end surface 31 a of the stopper 31. Therefore, the worm wheel 15 is disposed at the initial position Ps. Accordingly, the pole 23 released from the pressing force of the release lever 17 is urged by a pole return spring (not shown) and rotates so as to return to the rotation position shown in FIG.
　以上詳述したように、本実施形態によれば、以下に示す効果が得られるようになる。 As described in detail above, according to the present embodiment, the following effects can be obtained.
　（１）ウォームホイール１５は、トーションコイルスプリング３３を介在させてケース１１に組み付けられる。この場合、まず、トーションコイルスプリング３３の第１脚部３３ｂをケース１１の端面３１ｂに係止させた状態でトーションコイルスプリング３３がケース１１に仮組みされる。このとき、トーションコイルスプリング３３は、弾性復帰状態（自由状態）でケース１１に収容されており、第２脚部３３ｃは、ストッパ３１よりも該ストッパ３１の突出方向の外側に配置されている。続いて、ストッパ３１から外側への第２脚部３３ｃの突出部分の係合代で該第２脚部３３ｃが係合突部３２に係止される。そして、係合突部３２がストッパ３１を乗り越える位置、即ち初期位置Ｐｓに相当する位置まで、トーションコイルスプリング３３の付勢力に抗してウォームホイール１５が回動される。そして、この状態で、ウォームホイール１５をケース１１の底面に向かって軸方向に移動させると、第２脚部３３ｃ及び係合突部３２の係合代を増加しつつ該係合突部３２が周方向でストッパ３１の端面３１ａに当接する。そして、ウォームホイール１５は、トーションコイルスプリング３３を介在させた状態で初期位置Ｐｓに配置され、ケース１１へのウォームホイール１５の組付けが完了する。なお、ウォームホイール１５の組付け後においても、第２脚部３３ｃは、ストッパ３１よりも該ストッパ３１の突出方向の外側に配置されている。このように、ウォームホイール１５のケース１１への組付けを円滑に行うことができる。そして、ウォームホイール１５等の部材の組付作業を容易にするために、部材間に徒に間隙を設定する必要がないため、がたつきやこれに起因する異音の発生を抑えることができる。 (1) The worm wheel 15 is assembled to the case 11 with a torsion coil spring 33 interposed therebetween. In this case, first, the torsion coil spring 33 is temporarily assembled to the case 11 in a state where the first leg portion 33 b of the torsion coil spring 33 is engaged with the end surface 31 b of the case 11. At this time, the torsion coil spring 33 is accommodated in the case 11 in an elastic return state (free state), and the second leg portion 33 c is disposed outside the stopper 31 in the protruding direction of the stopper 31. Subsequently, the second leg portion 33 c is locked to the engagement protrusion 32 by the engagement margin of the protruding portion of the second leg portion 33 c outward from the stopper 31. Then, the worm wheel 15 is rotated against the biasing force of the torsion coil spring 33 to a position where the engaging protrusion 32 gets over the stopper 31, that is, a position corresponding to the initial position Ps. In this state, when the worm wheel 15 is moved in the axial direction toward the bottom surface of the case 11, the engagement protrusion 32 is increased while increasing the engagement margin of the second leg portion 33 c and the engagement protrusion 32. It contacts the end face 31a of the stopper 31 in the circumferential direction. The worm wheel 15 is disposed at the initial position Ps with the torsion coil spring 33 interposed, and the assembly of the worm wheel 15 to the case 11 is completed. Even after the worm wheel 15 is assembled, the second leg portion 33 c is disposed outside the stopper 31 in the protruding direction of the stopper 31. Thus, the assembly of the worm wheel 15 to the case 11 can be performed smoothly. Further, since it is not necessary to set a gap between the members in order to facilitate the assembly work of the members such as the worm wheel 15, it is possible to suppress the occurrence of rattling and abnormal noise resulting therefrom. .
　（２）ストッパ３１は、ウォームホイール１５を所定の最大回動位置Ｐｍに規制するストッパとして兼用する。これにより、例えば初期位置Ｐｓ用のストッパと最大回動位置Ｐｍ用のストッパとを個別に設ける場合に比べて、ケース１１をより簡素な形状にできる。 (2) The stopper 31 is also used as a stopper for restricting the worm wheel 15 to a predetermined maximum rotation position Pm. Thereby, for example, the case 11 can be made a simpler shape as compared with the case where the stopper for the initial position Ps and the stopper for the maximum rotation position Pm are individually provided.
　（３）ストッパ３１がウォームホイール１５を最大回動位置Ｐｍに規制する際、第２脚部３３ｃは、ストッパ３１よりも該ストッパ３１の突出方向の外側で係合突部３２に係止されている。従って、ストッパ３１がウォームホイール１５を最大回動位置Ｐｍに規制する際、第２脚部３３ｃが周方向でストッパ３１及び係合突部３２間に挟まることを抑制でき、第２脚部３３ｃの劣化を抑制することができる。 (3) When the stopper 31 restricts the worm wheel 15 to the maximum rotation position Pm, the second leg 33c is locked to the engaging protrusion 32 outside the stopper 31 in the protruding direction of the stopper 31. Yes. Therefore, when the stopper 31 restricts the worm wheel 15 to the maximum rotation position Pm, the second leg 33c can be prevented from being sandwiched between the stopper 31 and the engaging protrusion 32 in the circumferential direction, and the second leg 33c Deterioration can be suppressed.
　（４）ケース１１のストッパ３１によってウォームホイール１５（係合突部３２）の回動を規制する極めて簡易なストッパ構造を採用することができる。 (4) An extremely simple stopper structure that restricts the rotation of the worm wheel 15 (engagement protrusion 32) by the stopper 31 of the case 11 can be adopted.
　（５）トーションコイルスプリング３３ともどもウォームホイール１５を初期位置Ｐｓに組み付ける際に、ストッパ３１の第１端面３１ｃは、係合突部３２の第２端面３２ａと当接することにより当該組み付けを案内する。そのため、ウォームホイール１５及び前記トーションコイルスプリング３３の組付性を向上することができる。 (5) When the worm wheel 15 is assembled to the initial position Ps together with the torsion coil spring 33, the first end surface 31c of the stopper 31 abuts on the second end surface 32a of the engaging projection 32 to guide the assembly. Therefore, the assembling property of the worm wheel 15 and the torsion coil spring 33 can be improved.
　（６）ストッパ３１の第１端面３１ｃは、ウォームホイール１５の回転軸心を中心とした円弧形状である。そのため、該ウォームホイール１５を回転させて組み付ければ、第２端面３２ａを第１端面３１ｃに必ず当接させることができる。そのため、ウォームホイール１５及び前記トーションコイルスプリング３３の組付性をより向上させることができる。 (6) The first end face 31 c of the stopper 31 has an arc shape centered on the rotational axis of the worm wheel 15. Therefore, if the worm wheel 15 is rotated and assembled, the second end surface 32a can be brought into contact with the first end surface 31c without fail. Therefore, the assembling property of the worm wheel 15 and the torsion coil spring 33 can be further improved.
　なお、上記実施形態は以下のように変更してもよい。 Note that the above embodiment may be modified as follows.

In this case, a maximum rotation position stopper that restricts the worm wheel 15 to the maximum rotation position Pm may be separately provided at an appropriate position of the case 11. The stopper 31 that restricts the rotation of the worm wheel 15 only at the initial position Ps may be reduced in the circumferential direction. In this case, in the elastic return state (free state) of the torsion coil spring 33, the second leg portion 33c is engaged with the engaging protrusion 32 by the engagement margin of the protruding portion of the second leg portion 33c outward from the stopper 31. There is no wall portion (stopper 31) that can slide the engagement protrusion 32 when stopped.
　・トーションコイルスプリング３３の第１脚部３３ｂは、ストッパ３１の端面３１ｂ以外のケース１１の適宜位置に係止されていてもよい。 The first leg 33b of the torsion coil spring 33 may be locked at an appropriate position of the case 11 other than the end face 31b of the stopper 31.
　・第２脚部３３ｃがストッパ３１よりも該ストッパ３１の突出方向の外側に配置されているのであれば、上記実施形態の各部の形状等の構成は適宜変更されてもよい。例えば、ウォームホイール１５の組付け後にトーションコイルスプリング３３のコイル部３３ａが軸方向に圧縮されていてもよい。 As long as the second leg portion 33c is disposed outside the stopper 31 in the protruding direction of the stopper 31, the configuration of each part in the above embodiment may be appropriately changed. For example, the coil portion 33a of the torsion coil spring 33 may be compressed in the axial direction after the worm wheel 15 is assembled.
　・ストッパ３１の第１端面３１ｃ及び係合突部３２の第２端面３２ａの各々は、突出方向におけるいわゆる先端面に限定されるものではない。例えばストッパ３１又は係合突部３２の先端部に段差面が形成されてもよい。 Each of the first end surface 31c of the stopper 31 and the second end surface 32a of the engaging protrusion 32 is not limited to a so-called tip surface in the protruding direction. For example, a step surface may be formed at the tip of the stopper 31 or the engaging protrusion 32.
　・出力部材は、ウォームギヤを構成するウォームホイール１５に限定されるものではなく、電動モータ１２に駆動される適宜のギヤやレバーであってもよい。 The output member is not limited to the worm wheel 15 constituting the worm gear, and may be an appropriate gear or lever driven by the electric motor 12.
　・本発明は、車両ドアを閉状態で保持すべくラッチ機構２１を駆動するクローザ装置に適用されてもよい。あるいは、本発明は、電動モータの駆動力によりトーションコイルスプリングの付勢力に抗して出力部材を回転させて所要の動作を行う適宜の装置に適用されてもよい。 The present invention may be applied to a closer device that drives the latch mechanism 21 to hold the vehicle door in a closed state. Alternatively, the present invention may be applied to an appropriate device that performs a required operation by rotating the output member against the biasing force of the torsion coil spring by the driving force of the electric motor.
