Description

本発明は、車両用扉の自動開閉装置において故障時に手動操作に切り換えられる手動切換機構に関する。   The present invention relates to a manual switching mechanism that can be switched to manual operation when a failure occurs in an automatic opening / closing device for a vehicle door.

従来、車両用扉の自動開閉装置として、特許文献１には、後部扉に内蔵された電動モータを駆動源とし、先端がセンターピラーに枢着され、後部扉のヒンジ側端部より出没自在に設けた扉開閉用ロッドの基端をクランクに枢着し、該クランクを外方突設した従動歯車と、該従動歯車に噛合した正逆回転自在な駆動歯車を前記駆動源に連繋したものが開示されている。
この自動開閉装置は、ドアロック解除装置にも連繋され、該ドアロック解除装置によって、開放時に後部扉に内装したドアロックのラッチによる車体側のストライカーの係合を解除した後、自動開閉装置の駆動源が作動し、クランクを後部扉の開放方向へ揺動させることにより、扉開閉用ロッドがセンターピラーを押圧して後部扉を開放する。
又、後部扉を閉鎖する場合、駆動源の作動により、クランクを上記と逆方向に揺動させることで、扉開閉用ロッドを引張して後部扉を閉鎖方向へ回動させ、ドアロックのラッチがストライカーに正規に係合するフルラッチ位置に達すると後部扉が施錠される。

JP 2004-190413 A

しかしながら、上記自動開閉装置は、駆動源に連繋した駆動歯車を従動歯車に噛合しているだけのため、特に後部扉の開放時において、駆動源が故障した場合、後部扉を閉鎖することができず、かかる状態では、走行できないといった課題を有していた。
そこで、本発明では、上記車両用扉の自動開閉装置において、駆動系に故障が発生した場合、駆動系と従動系の連繋を遮断し、手動で後部扉を開閉操作可能と成した手動切換機構を提供することを目的としている。 However, since the automatic opening / closing device only meshes the drive gear connected to the drive source with the driven gear, the rear door can be closed when the drive source fails, particularly when the rear door is opened. However, in such a state, there was a problem that it was not possible to run.
Therefore, in the present invention, in the automatic opening / closing device for a vehicle door, when a drive system malfunctions, a manual switching mechanism that cuts off the connection between the drive system and the driven system and can manually open and close the rear door. The purpose is to provide.

上記課題に鑑み、本発明のものは、車両用扉の扉開閉用ロッドに連繋して成るクランクを従動軸の一端に設け、他端に従動歯車を設け、該従動歯車に駆動歯車を噛合した車両用扉の自動開閉装置において、従動軸は、その他端側を基板の表裏に渡って貫通した軸孔に挿通すると共に、一端側に軸孔より大径な大径部を膨出形成し、該大径部の一端面とこれに対向する基板表面間の空隙に抜脱可能なスペーサを介装し、該スペーサの空隙介在状態では基板裏面における軸孔の開口端面に従動歯車の軸回り端面を摺接させると共に、従動歯車の駆動歯車との噛合状態が保持され、スペーサにはこれを前記空隙から抜脱すると共に、従動軸を基板裏面へ押圧して従動歯車の駆動歯車との噛合を解除する歯車離間手段を設けたことを特徴とする。
又、スペーサは、基板表面上に従動軸を介して基端が枢着された一対の槓杆から成り、該槓杆は先端同士の間隔を狭める方向に付勢され、歯車離間手段は、スペーサの上記空隙介在状態で従動軸が回転可能な間隔を有する様に槓杆先端間に挟持され、外部からの操作にて回転することによりスペーサが上記空隙から抜出可能に前記間隔を押し広げるカム板を基板表面上に枢着すると共に、カム板の適所より従動軸の一端側へ鉤状のレバーを突設して成り、該レバーの先端はカム板の前記回転によりスペーサが上記空隙より抜出した時に従動軸の一端面に設けた円錐台状の凸部を摺動圧接する様に設けたことを特徴とする。 In view of the above problems, the present invention provides a crank connected to a door opening / closing rod of a vehicle door at one end of a driven shaft, a driven gear at the other end, and a drive gear meshed with the driven gear. In the automatic door opening and closing device for a vehicle door, the driven shaft is inserted into a shaft hole penetrating the other end side across the front and back of the substrate, and a large diameter portion larger than the shaft hole is formed to bulge on one end side, A removable spacer is interposed in the gap between the one end surface of the large-diameter portion and the substrate surface facing the large-diameter portion. When the spacer is interposed, the end surface around the axis of the driven gear of the shaft hole on the back surface of the substrate is provided. Is engaged with the drive gear of the driven gear, the spacer is removed from the gap, and the driven shaft is pressed against the back of the substrate to engage the drive gear of the driven gear. A gear separating means for releasing is provided.
The spacer is composed of a pair of hooks whose base ends are pivotally attached via a driven shaft on the substrate surface, the hooks are urged in the direction of narrowing the distance between the tips, and the gear separating means A cam plate is sandwiched between the tips of the flanges so that the driven shaft has a rotatable interval with the gap interposed therebetween, and the spacer is rotated by an external operation so that the spacer can be pulled out of the gap to extend the gap. It is pivotally mounted on the surface, and a hook-shaped lever protrudes from an appropriate position on the cam plate to one end of the driven shaft, and the tip of the lever is driven when the spacer is extracted from the gap by the rotation of the cam plate. A truncated cone-shaped convex portion provided on one end surface of the shaft is provided so as to be in sliding contact.

要するに請求項１に係る発明のものは、車両用扉の扉開閉用ロッドに連繋して成るクランクを従動軸の一端に設け、他端に従動歯車を設け、該従動歯車に駆動歯車を噛合した車両用扉の自動開閉装置において、従動軸は、その他端側を基板の表裏に渡って貫通した軸孔に挿通すると共に、一端側に軸孔より大径な大径部を膨出形成し、該大径部の一端面とこれに対向する基板表面間の空隙に抜脱可能なスペーサを介装し、該スペーサの空隙介在状態では基板裏面における軸孔の開口端面に従動歯車の軸回り端面を摺接させると共に、従動歯車の駆動歯車との噛合状態が保持されるので、通常は従動軸の軸方向の移動が規制され、駆動歯車の駆動力が従動歯車に確実に伝動され、従動軸を介してクランクが揺動し、扉開閉用ロッドを進退動させて車両用扉を自動的に開閉できる。
そして、万一、上記自動開閉装置における駆動系が故障した場合、歯車離間手段にて、スペーサを上記空隙から抜脱することで従動軸の軸方向の移動を可能と成すと共に、該従動軸を基板裏面へ押圧して従動歯車の駆動歯車との噛合を解除することにより、従動軸を自由に回転できる様にして車両用扉を手動で開閉させられるため、例え車両扉の開放中に故障しても車両扉を閉鎖でき、支障なく車両を走行させることができる。 In short, the invention according to claim 1 has a crank connected to a door opening / closing rod of a vehicle door provided at one end of a driven shaft, a driven gear provided at the other end, and a driving gear meshed with the driven gear. In the automatic door opening and closing device for a vehicle door, the driven shaft is inserted into a shaft hole penetrating the other end side across the front and back of the substrate, and a large diameter portion larger than the shaft hole is formed to bulge on one end side, A removable spacer is interposed in the gap between the one end surface of the large-diameter portion and the substrate surface facing the large-diameter portion. When the spacer is interposed, the end surface around the axis of the driven gear of the shaft hole on the back surface of the substrate is provided. Since the meshing state of the driven gear with the driving gear is maintained, the movement of the driven shaft in the axial direction is normally restricted, and the driving force of the driving gear is reliably transmitted to the driven gear. Through which the crank swings and the door opening / closing rod moves forward and backward. The door for the vehicle can be automatically opened and closed.
In the unlikely event that the drive system in the automatic opening / closing device fails, the gear separation means allows the driven shaft to move in the axial direction by removing the spacer from the gap, and the driven shaft is By releasing the meshing with the drive gear of the driven gear by pressing against the back of the board, the vehicle door can be manually opened and closed so that the driven shaft can be freely rotated. However, the vehicle door can be closed and the vehicle can be run without hindrance.

請求項２に係る発明では、スペーサは、基板表面上に従動軸を介して基端が枢着された一対の槓杆から成り、該槓杆は先端同士の間隔を狭める方向に付勢され、歯車離間手段は、スペーサの上記空隙介在状態で従動軸が回転可能な間隔を有する様に槓杆先端間に挟持され、外部からの操作にて回転することによりスペーサが上記空隙から抜出可能に前記間隔を押し広げるカム板を基板表面上に枢着すると共に、カム板の適所より従動軸の一端側へ鉤状のレバーを突設して成り、該レバーの先端はカム板の前記回転によりスペーサが上記空隙より抜出した時に従動軸の一端面に設けた円錐台状の凸部を摺動圧接する様に設けたので、上記自動開閉装置における駆動系に故障が生じた場合、外部操作にてカムを回転させることのみで、スペーサを大径部と基板間の空隙から抜脱させることができると共に、この後にレバー先端が凸部を摺動圧接して従動軸を基板裏面へ押圧するため、従動歯車を駆動歯車との噛合位置からその軸方向における噛合解除位置へと移動させることができて、従動軸を上記の様に自由に回転可能と成すことができる。
よって、本発明によれば、カムを上記の如く回転させる操作のみによって、従動軸をフリーにするための２動作（空隙からのスペーサの抜脱動作と、従動軸の軸方向の押進動作）を簡単容易に行え、その操作性を良好と成すことができる等その実用的効果甚だ大である。 In the invention according to claim 2, the spacer is composed of a pair of hooks whose base ends are pivotally mounted on the surface of the substrate via the driven shaft, and the hooks are urged in the direction of narrowing the distance between the tips to separate the gears. The means is sandwiched between the flange tips so that the driven shaft has a rotatable interval in the space interposed state of the spacer, and is rotated by an external operation so that the spacer can be extracted from the gap. A cam plate to be spread is pivotally mounted on the surface of the substrate, and a hook-shaped lever is projected from an appropriate position of the cam plate to one end of the driven shaft. Since the frustoconical convex portion provided on one end face of the driven shaft is provided so as to be in sliding contact when extracted from the gap, if the drive system in the automatic switching device fails, the cam can be operated by external operation. Simply rotate the spacer. In addition to being able to be removed from the gap between the diameter portion and the substrate, and then the lever tip slide-contacts the convex portion to press the driven shaft against the back surface of the substrate, so that the driven gear is moved from the meshing position with the drive gear. It can be moved to the meshing release position in the axial direction, and the driven shaft can be freely rotated as described above.
Therefore, according to the present invention, the two operations for making the driven shaft free only by the operation of rotating the cam as described above (the operation for removing the spacer from the gap and the pushing operation in the axial direction of the driven shaft). Can be easily and easily performed, and the operability thereof is good.

以下本発明の実施の一形態例を図面に基づいて説明する。
図１は、自動開閉装置１を内装した車両の後部扉２（以下、車両用扉２と称する。）の内部構造を示す簡略図、図２〜４は自動開閉装置１の正面図、平面図、背面図である。

The vehicle door 2 is hinged to a center pillar (not shown) of the vehicle body, and a door opening / closing rod 3 having a distal end pivotally attached to the center pillar and a proximal end connected to the automatic opening / closing device 1 is connected to the vehicle door. 2 so that it can be inserted and retracted through the hinge side end 2a.

自動開閉装置１は、これと共に車両用扉２に内装されたドアロック解除装置４に連繋され、電動モータを駆動源５としており、該駆動源５は車両用扉２内の適所に固定した基板６に取付けられ、該基板６の表面6a側から裏面6b側へ貫通突出した駆動源５の駆動軸5aに非円形の駆動歯車７を軸着している。
又、基板６には、従動軸８が回転自在に設けられ、該従動軸８は、その一端8aに扉開閉用ロッド３の基端を枢着したクランク９の基端を軸着し、他端8bに非円形の従動歯車10を軸着し、該従動歯車10を駆動歯車７に噛合しており、従動歯車10の回転角を車両用扉２の開度に対応、即ち従動歯車10の回転角に応じ揺動するクランク９に対応して車両用扉２が開閉する様に成している。 The automatic opening / closing device 1 is connected to a door lock releasing device 4 built in the vehicle door 2 together with the automatic opening / closing device 1 and uses an electric motor as a drive source 5, and the drive source 5 is fixed to an appropriate place in the vehicle door 2. A non-circular drive gear 7 is attached to a drive shaft 5a of a drive source 5 that is attached to 6 and protrudes from the front surface 6a side to the back surface 6b side of the substrate 6.
Further, a driven shaft 8 is rotatably provided on the substrate 6, and the driven shaft 8 is pivotally attached to one end 8a of the base end of a crank 9 pivotally attached to the base end of the door opening / closing rod 3. A non-circular driven gear 10 is axially attached to the end 8b, and the driven gear 10 is engaged with the drive gear 7. The rotational angle of the driven gear 10 corresponds to the opening of the vehicle door 2, that is, the driven gear 10 The vehicle door 2 is configured to open and close in response to the crank 9 that swings according to the rotation angle.

駆動歯車７と従動歯車10は、厚みが同一でいずれも異形な非円形状に形成され、駆動軸5aの正逆回転により、クランク９を不等速に揺動する様に成し、この一組の相互に噛合している非円形歯車７、10の速度比は、車両用扉２の閉鎖度合に応じ徐々に速くなる様に設定され、車両用扉２の閉じる瞬間に最高速となる速度比を有する様に成している。
従って、車両用扉２の閉鎖スピードは徐々に速くなり、閉じる瞬間が最も速く、車両用扉２の開放スピードは開放直後よりも全開に至る間際の方が遅くなる。 The drive gear 7 and the driven gear 10 are formed in non-circular shapes having the same thickness and both having an irregular shape, and the crank 9 is oscillated at unequal speed by forward and reverse rotation of the drive shaft 5a. The speed ratio of the non-circular gears 7 and 10 meshing with each other is set so as to gradually increase according to the degree of closing of the vehicle door 2, and the speed at which the vehicle door 2 closes becomes the highest speed. It is made to have a ratio.
Accordingly, the closing speed of the vehicle door 2 is gradually increased, the moment of closing is the fastest, and the opening speed of the vehicle door 2 is slower when it is fully opened than immediately after opening.

従動軸８は、その他端8b側を基板６の表裏6a、6bに渡って貫通した軸孔11ａに回転自在に挿通しており、該軸孔11ａは基板裏面6bに突設した円筒状の軸受け11内の中空部である。

又、従動軸８の一端面には、円錐台状の凸部14を突設している。
尚、クランク９は、その基端を従動軸８に一体化された大径部（カラー）12に軸着している。 The driven shaft 8 is rotatably inserted in a shaft hole 11a penetrating the other end 8b side of the substrate 6 across the front and back surfaces 6a and 6b. The shaft hole 11a is a cylindrical bearing protruding from the substrate back surface 6b. 11 is a hollow portion.
A large-diameter portion 12 having a larger diameter than the shaft hole 11a is formed on one end side of the driven shaft 8 protruding from the substrate surface 6a, and the large-diameter portion 12 is predetermined from one end of the driven shaft 8. The collar 12 is externally fitted over the length, and the collar 12 is integrated with the driven shaft 8 by sinking into each key groove formed together with the driven shaft 8 and attaching a key 13.
Further, a frustoconical convex portion 14 is projected from one end surface of the driven shaft 8.
The crank 9 has a base end pivotally attached to a large diameter portion (collar) 12 integrated with the driven shaft 8.

そして、大径部12の一端面12ａとこれに対向する基板表面6a間の空隙Ｓに抜脱可能なスペーサ15を介装し、該スペーサ15の空隙介在状態では、基板裏面6bにおける軸孔11ａの開口端面11ｂに従動歯車10の軸回り端面10ａを摺接させると共に、駆動歯車８との噛合位置に従動歯車10が合致して従動歯車10の駆動歯車７との噛合状態が保持される様に成している。
スペーサ15は、基板表面6a上に従動軸８を介して基端が枢着された一対の槓杆16、16ａから成り、該槓杆16、16ａは、その先端外側面に刻設した凹溝に大径部12に巻装した捩じりコイルばね17の各端部を固定し、該捩じりコイルばね17により、槓杆16、16ａはその先端同士の間隔を狭める方向に付勢される。
又、基板表面6aにおいて、スペーサ15を介した上方には、大径部12を挿通した支持板18が固定されている。 Then, a removable spacer 15 is interposed in the space S between the one end surface 12a of the large diameter portion 12 and the substrate surface 6a opposite to the one end surface 12a. The opening end face 11b of the driven gear 10 is brought into sliding contact with the end face 10a around the axis of the driven gear 10, and the driven gear 10 is matched with the driven gear 8 so that the engaged state with the drive gear 7 of the driven gear 10 is maintained.

The tip of the lever 21 (curved portion 21b) is bent upward so that the lower surface thereof corresponds to the inclination of the convex portion 14, and the flanges 16, 16a are expanded by the rotation of the cam plate 20. After pulling out from the gap S, the inclined lower end of the lever 21 slides on the inclined surface of the convex portion 14 and presses it, and the inclined lower edge of the lever 21 reaches the top of the convex portion 14. At the time (see FIGS. 7 and 8), one end surface 12a of the large diameter portion 12 of the driven shaft 8 is brought into contact with the substrate surface 6a, and the driven gear 10 is axially moved. Forms so as to be separated from the drive gear 7.

操作手段22は、レバー21の支持杆部21ａに基端を掛止したワイヤから成り、該ワイヤ22は、カム板20のスペーサ15（槓杆16、16ａ）を空隙Ｓから抜出させる回転方向（反時計回り）へのみ引張可能に弛緩状態で配索し、ワイヤ22先端に形成したループ22ａを車両用扉２のインナーパネル（図示せず）を貫通してその外側へ露出させている。
尚、ワイヤ22は、途中で支持板18適所より該支持板18と同一平面上に延設した突片18ａに設けた貫通孔を挿通することにより、方向転換してインナーパネルへループ22ａが指向する様に成した上でインナーパネルを貫通している。 The operating means 22 is composed of a wire whose base end is hooked on the support collar portion 21a of the lever 21, and the wire 22 rotates in the rotational direction (withdrawing the spacer 15 (ridges 16, 16a) of the cam plate 20 from the gap S ( A loop 22a formed at the tip of the wire 22 passes through an inner panel (not shown) of the vehicle door 2 and is exposed to the outside.
The direction of the wire 22 is changed by inserting a through-hole provided in a projecting piece 18a extending on the same plane as the support plate 18 from a suitable position in the middle of the wire 22 so that the loop 22a is directed to the inner panel. After doing so, it penetrates through the inner panel.

ドアロック解除装置４は、車両用扉２に内装した図示しないドアロックに組み付けて成り、車両用扉２の開放時にドアロックに組み込まれたラッチによる車体側のストライカーの係合を解除するものであり、このドアロック解除装置４によるドアロック解除後、自動開閉装置１の駆動源５が作動し、車両用扉２を開放操作する様に成している。   The door lock release device 4 is assembled to a door lock (not shown) built in the vehicle door 2 and releases the engagement of the striker on the vehicle body by a latch incorporated in the door lock when the vehicle door 2 is opened. Yes, after the door lock is released by the door lock release device 4, the drive source 5 of the automatic opening / closing device 1 is operated to open the vehicle door 2.

次に、自動開閉装置１の動作について説明する。
通常は、スペーサ15（槓杆16、16ａ）は、空隙Ｓに介在されており、かかる空隙介在状態は、捩じりコイルばね17の付勢力にて維持されると共に、カム板20は従動軸８が回転可能な間隔を有する様に槓杆16、16ａ先端間に挟持されている。
従って、従動軸８は、その大径部12の一端面12ａが槓杆16、16ａ表面に摺接可能に当接し、基板裏面6bにおける軸孔11ａの開口端面11ｂに従動歯車10の軸回り端面10ａに摺接可能に当接し、これにより軸方向の移動が規制され、かかる状態にて従動歯車10が駆動歯車７に噛合し、該駆動歯車７の駆動力が伝動される様に成している（図５、６参照）。 Next, the operation of the automatic opening / closing device 1 will be described.
Normally, the spacer 15 (槓杆 16, 16 a) is interposed in the gap S. This gap interposed state is maintained by the urging force of the torsion coil spring 17, and the cam plate 20 is driven by the driven shaft 8. Is sandwiched between the tips of the flanges 16 and 16a so as to have a rotatable interval.
Therefore, the driven shaft 8 has one end surface 12a of the large-diameter portion 12 abutting on the surfaces of the flanges 16 and 16a so as to be slidable, and the end surface 10a around the axis of the driven gear 10 on the opening end surface 11b of the shaft hole 11a in the substrate rear surface 6b. In this state, the driven gear 10 is engaged with the drive gear 7, and the driving force of the drive gear 7 is transmitted. (See FIGS. 5 and 6).

又、車両用扉２の閉鎖状態では、ドアロックのラッチが車体側のストライカーにフルラッチ位置で係合し、図１中二点鎖線で示す様に、クランク９が扉開閉用ロッド３を車両用扉２の閉鎖方向へ引張保持する回転位置で従動歯車10と駆動歯車７は噛合している。
そして、車両用扉２の開放時には、先ず、ドアロック解除装置４が作動し、ドアロックのラッチによるストライカーとの係合を解除し、その直後に自動開閉装置１の駆動源５が作動する。 When the vehicle door 2 is closed, the door lock latch engages with the striker on the vehicle body side at the full latch position, and as shown by the two-dot chain line in FIG. The driven gear 10 and the drive gear 7 are meshed with each other at the rotational position where the door 2 is pulled and held in the closing direction.
When the vehicle door 2 is opened, first, the door lock releasing device 4 is operated to release the engagement with the striker by the door lock latch, and immediately thereafter, the drive source 5 of the automatic opening / closing device 1 is operated.

これにより、駆動歯車７が回動し、これに噛合している従動歯車10の回転により、従動軸８を介してクランク９が車両用扉２の開放方向へ揺動し、扉開閉用ロッド３がセンターピラーを押圧して車両用扉２が開放される（図１、４参照）。
この開放時における車両用扉２の開放スピードは、開放される瞬間がもっとも速く、その後徐々に遅くなり、クランク９が車両用扉２の全開に対応した揺動位置に到達した時に、駆動源５が停止して車両用扉２の開放が完了する。
この開放時における車両用扉２の開放スピードが徐々に遅くなるので、全開に至る間際に車両用扉２のヒンジ等にかかる衝撃が軽減される。 As a result, the drive gear 7 is rotated, and the driven gear 10 meshing with the drive gear 7 is rotated, whereby the crank 9 is swung in the opening direction of the vehicle door 2 via the driven shaft 8, and the door opening / closing rod 3. Presses the center pillar to open the vehicle door 2 (see FIGS. 1 and 4).
The opening speed of the vehicle door 2 at the time of opening is the fastest at the moment of opening, and then gradually slows down. When the crank 9 reaches the swing position corresponding to the fully open of the vehicle door 2, the driving source 5 Stops and the opening of the vehicle door 2 is completed.
Since the opening speed of the vehicle door 2 at the time of opening gradually decreases, the impact applied to the hinges and the like of the vehicle door 2 immediately before reaching the full opening is reduced.

又、車両用扉２を閉鎖する場合、駆動源５の作動により、駆動歯車７が上記と逆方向に回動し、同様に上記と逆方向に回転する従動歯車10により、クランク９が上記と逆方向に揺動することで、扉開閉用ロッド３を引張して車両用扉２を閉鎖方向へ回動させる。
この閉鎖時における車両用扉２の閉鎖スピードは、開放時とは逆に車両用扉２の開度が狭くなるに従い徐々に速くなり、閉鎖される瞬間に最も速くなって車両用扉２を勢い良く閉じ、これにより、ドアロックのラッチがストライカーに正規に係合するフルラッチ位置に達し、車両用扉２がロックされることとなる。 When the vehicle door 2 is closed, the drive gear 7 is rotated in the opposite direction by the operation of the drive source 5, and the crank 9 is rotated by the driven gear 10 which is similarly rotated in the opposite direction. By swinging in the reverse direction, the door opening / closing rod 3 is pulled to rotate the vehicle door 2 in the closing direction.
The closing speed of the vehicle door 2 at the time of closing is gradually increased as the opening degree of the vehicle door 2 is narrowed, contrary to that at the time of opening. It closes well, and thereby the door lock latch reaches the full latch position where the striker is properly engaged, and the vehicle door 2 is locked.

そして、万一、駆動源５が故障した場合、車両用扉２のインナーパネルに露出しているワイヤ22先端のループ22ａを引張して緊張させる。
これにより、ワイヤ22の基端が掛止された支持杆部21ａが、カム板20のスペーサ15（槓杆16、16ａ）を空隙Ｓから抜出させる回転方向（反時計回り）へ捩じりコイルばね17の付勢力に抗して回転し、カム板20とレバー21を同方向に回転させる（図５、６参照）。 If the drive source 5 fails, the loop 22a at the tip of the wire 22 exposed on the inner panel of the vehicle door 2 is pulled and tensioned.
As a result, the support flange 21a with the proximal end of the wire 22 hooked is twisted in the rotational direction (counterclockwise) in which the spacer 15 (ス ペ ー サ 16, 16a) of the cam plate 20 is extracted from the gap S. It rotates against the urging force of the spring 17 and rotates the cam plate 20 and the lever 21 in the same direction (see FIGS. 5 and 6).

カム板20の回転により、槓杆16、16ａの先端は外側へ押圧され、相互に離間する様に揺動し、この揺動により槓杆16、16ａが空隙Ｓから完全に抜脱すると、従動軸８の軸方向の移動が可能となる。
その後もカム板20は回転し、レバー21（曲臂部21ｂ）の傾斜した先端下面が凸部14の傾斜面上に達すると、該傾斜面上をレバー21の傾斜した先端下面が摺動しながら凸部14を圧接する。 When the cam plate 20 rotates, the tips of the flanges 16 and 16a are pressed outward and swing away from each other. When the flanges 16 and 16a are completely removed from the gap S by this swing, the driven shaft 8 It is possible to move in the axial direction.
Thereafter, the cam plate 20 continues to rotate, and when the inclined lower surface of the lever 21 (curved portion 21b) reaches the inclined surface of the convex portion 14, the inclined lower surface of the lever 21 slides on the inclined surface. Then, the convex portion 14 is pressed.

これにより、従動軸８は徐々に基板裏面6b側へ移動し、レバー21先端の傾斜下縁が凸部14の頂部上に達した時点で従動軸８における大径部12の一端面12ａが基板表面6a上に当接して従動歯車10をその軸方向で駆動歯車７より離間させ、両歯車７、10の噛合を解除する（図７、８参照）。
上記の様に、両歯車７、10の噛合が解除されると、従動軸８が自由に回転できるので、車両用扉２を手動で開閉させられ、例え車両扉２の開放中に駆動源５が故障しても車両扉２を閉鎖できる。 As a result, the driven shaft 8 gradually moves to the substrate back surface 6b side, and when the inclined lower edge of the tip of the lever 21 reaches the top of the convex portion 14, the one end surface 12a of the large diameter portion 12 of the driven shaft 8 becomes the substrate. Abutting on the surface 6a, the driven gear 10 is separated from the drive gear 7 in its axial direction, and the meshing of both gears 7, 10 is released (see FIGS. 7 and 8).
As described above, when the meshing between the two gears 7 and 10 is released, the driven shaft 8 can freely rotate, so that the vehicle door 2 can be manually opened and closed, for example, while the vehicle door 2 is opened, the drive source 5 Even if the vehicle breaks down, the vehicle door 2 can be closed.
