Description

  The present invention relates to a vehicle opening / closing device that opens and closes a slide door provided in a vehicle by power of a drive source.

  As a vehicle opening / closing device that opens and closes a sliding door provided on the side of a vehicle body of a vehicle such as a wagon car or a one-box vehicle by the power of a driving source, a pair of cables on the opening side and the closing side from the vehicle front-rear direction is used as the sliding door A cable type is known in which these cables are connected and driven by a drive unit using an electric motor or the like as a drive source so that the sliding door is opened and closed while being pulled by the cable.

  On the other hand, the vehicle is provided with a door lock mechanism in order to hold the closed slide door in the fully closed position. The door lock mechanism includes a striker that is fixed to either the vehicle body or the slide door and a latch that is provided to the other so that the vehicle body and the slide door can be locked and unlocked. When closed, the latch engages the striker and rotates to the full latch position. In addition, the door lock mechanism is provided with a ratchet. When the latch rotates to the full latch position, the ratchet engages with the latch, thereby restricting the rotation of the latch in the unlatching direction, and the sliding door is in the fully closed position. Is supposed to be retained.

  By the way, when the sliding door is fully closed, a door seal material is provided on one side of the portion where the sliding door and the vehicle body face each other to prevent rainwater from entering the vehicle interior when the sliding door is fully closed. It is arranged so that it can be elastically contacted with the other side when fully closed. For this reason, when the sliding door is closed to the half-door position and further pulled to the fully-closed position, a force that deforms (or compresses) the sealing material is required, and the sliding door is half-powered by the force of the drive unit alone. It may be difficult to pull in from the door position to the fully closed position.

  Thus, for example, in the opening / closing device disclosed in Patent Document 1, a closer mechanism for pull-in operation is separately provided in addition to the drive unit for automatically opening and closing the sliding door, and when the sliding door is closed to the half-door position. The latch engaged with the striker by the closer mechanism is driven from the unlatched position to the fully latched position, and the slide door is pulled to the fully closed position.

  Further, when the closed sliding door is automatically opened, it is necessary to release the holding of the sliding door by the door lock mechanism, that is, the engagement of the ratchet latch. Therefore, for example, in the opening / closing apparatus disclosed in Patent Document 1, a releaser mechanism for releasing the door lock mechanism is separately provided in addition to the drive unit, and when the sliding door is automatically opened from the fully closed position, the ratchet is engaged by the releaser mechanism. By driving from the position to the release position, the release operation is performed and the holding of the slide door by the door lock mechanism is automatically released.

On the other hand, vehicles equipped with a door lock mechanism (open state holding mechanism) for holding the opened slide door in a predetermined open position are also known. For example, when the slide door is opened to the fully open position, the vehicle is covered. The engaging member (hook) is engaged with the engaging member, and the slide door is held in the fully open position.

Accordingly, the drive arms 82 and 83 are prevented from malfunctioning due to unexpected slight rotation of the carrier 45.

  FIGS. 14A to 14C are explanatory views showing the procedure for driving the releaser release cable by the releaser driving mechanism, respectively. FIGS. 15A and 15B are the releaser cable for closing operation by the releaser driving mechanism. It is explanatory drawing which shows the drive procedure.

  In a state where the slide door 14 is held at the fully closed position by the door lock mechanism 51, the drum 37 is in a state of being restrained by the vehicle body 12 via the open side cable 25 a and the slide door 14. Therefore, when the slide door 14 is held in the fully closed position by the door lock mechanism 51, when the opening side of the opening / closing switch (not shown) is operated and the output shaft 35 of the motor 32 with speed reducer rotates in the opening direction, The rotational force is transmitted to the carrier 45, and the carrier 45 rotates counterclockwise as shown in FIG. When the carrier 45 rotates in the counterclockwise direction in FIG. 14, as shown in FIG. 14B, the engagement protrusion 82a is pushed by the opening operation drive portion 89a, and the opening operation drive arm 82 is moved to the guide grooves 87a, It moves along 88a and the releaser cable 74 for opening operation operates. When the opening operation releaser cable 74 is operated, the ratchet 56 is released by the opening operation releaser mechanism 71, and the holding of the slide door 14 to the fully closed position by the door lock mechanism 51 is released, as shown in FIG. .

  When the holding of the slide door 14 to the fully closed position by the door lock mechanism 51 is released, the restraint of the drum 37 by the open side cable 25a is released, whereby the rotational force of the output shaft 35 is transmitted to the drum 37, As shown in FIG. 8A, the drum 37 rotates in the opening direction, and the slide door 14 automatically opens toward the fully open position.

  When the slide door 14 reaches the fully open position and is held at the fully open position by the fully open hook mechanism 61, the motor 32 with a speed reducer is stopped by the control device, and then the electromagnetic clutch is switched to the power cut-off state. Thus, the carrier 45 is pulled by the spring force of the return spring that urges the releaser lever 72 via the opening releaser cable 74 as shown in FIG. It is driven by the opening operation drive arm 82 to return to the initial position.

  Next, in a state where the slide door 14 is held at the fully open position by the fully open hook mechanism 61, the drum 37 is in a state of being restrained by the vehicle body 12 via the closed cable 25 b and the slide door 14. Therefore, when the slide door 14 is held in the fully open position by the fully open hook mechanism 61, when the closing side of an open / close switch (not shown) is operated and the output shaft 35 of the motor 32 with a speed reducer rotates in the closing direction, The rotational force is transmitted to the carrier 45, and the carrier 45 rotates clockwise as shown in FIG. When the carrier 45 rotates in the clockwise direction in FIG. 15, as shown in FIG. 15B, the engagement protrusion 83a is pushed by the closing operation drive portion 89b, and the closing operation drive arm 83 is moved to the guide grooves 87b, 88b. The releaser cable 76 for closing operation is operated. When the closing operation releaser cable 76 is operated, the locking mechanism 66 is released by the closing operation releaser mechanism 75 as shown in FIG. 12, and the holding of the slide door 14 to the fully opened position by the fully opening hook mechanism 61 is released. .

  When the holding of the slide door 14 to the fully opened position by the fully opened hook mechanism 61 is released, the restraint of the drum 37 by the closed cable 25b is released, whereby the rotational force of the output shaft 35 is transmitted to the drum 37, As shown in FIG. 8B, the drum 37 rotates in the closing direction, and the slide door 14 automatically closes toward the fully closed position.

  As described above, when the slide door 14 is held at the fully closed position by the operation of the door lock mechanism 51, the motor 32 with the speed reducer is stopped by the control device, and then the electromagnetic clutch is switched to the power cut-off state. . Thus, the closing operation drive arm 83 is pulled by the spring force of the urging means provided in the closing operation releaser mechanism 75 via the closing operation releaser cable 76 so that the initial state shown in FIG. 13 is obtained. In addition, the carrier 45 is driven by the closing operation driving arm 83 to return to the initial position.

  Thus, in this opening / closing device 24, when the sliding door 14 is driven by the drive unit 31 and automatically opened from the fully closed position, the opening / closing device 24 is opened by the output of the motor 32 with a speed reducer for automatically opening and closing the sliding door 14. The drive arm 82 for operation can be driven and the ratchet 56 engaged with the latch 53 can be automatically released. Further, in this opening / closing device 24, when the slide door 14 is driven by the drive unit 31 and automatically closed from the fully open position, the closing drive is driven by the output of the motor 32 with a speed reducer for automatically opening and closing the slide door 14. The arm 83 can be driven to release the lock mechanism 66 of the fully open hook mechanism 61. Therefore, for the releaser mechanism, that is, without providing another motor with a speed reducer for releasing the ratchet 56 and the lock mechanism 66, the slide door 14 is automatically opened and closed by the single motor 32 with the speed reducer and the door. The lock mechanism 51 and the fully open hook mechanism 61 can be released. Thereby, this opening / closing device 24 can be reduced in size, and the mounting property to the vehicle body 12 can be improved.

  In order to transmit the rotation of the output shaft 35 to the drum 37, it is necessary not only to release the restraint of the drum 37 by the cables 25a and 25b, but also to restrain the carrier 45 so that it cannot rotate. Will be described later.

  As shown in FIG. 9, the opening / closing device 24 is provided with a closer mechanism 91 for pulling the slide door 14 closed to the half door position to the fully closed position against the elastic force of the door seal material 14a. It has been.

  In this embodiment, the slide door 14 is set to the half door position when the roller assembly 22 reaches the curved portion of the center rail 18, and the roller assembly 22 is driven by moving the curved portion. The slide door 14 is retracted by the closer mechanism 91 within a range where loss occurs.

  As shown in FIG. 9, the closer mechanism 91 has a drive lever 92 for driving the latch 53 in the full latch direction. The drive lever 92 is rotatably supported by the base bracket 52 of the door lock mechanism 51 by a support shaft 93 at a base end portion thereof, and a closer cable 94 as a closing connecting member is provided at a connecting portion 92a provided at the distal end side thereof. The tips of are connected. One end of a connection link 96 is rotatably connected to an intermediate portion of the drive lever 92 by a pin member 95, and the other end of the connection link 96 is rotatably connected to the latch 53 by a pin member 97. That is, the drive lever 92 is connected to the latch 53 by the connecting link 96 and interlocked with the latch 53.

  A spring 98 is attached to the support shaft 93, and the drive lever 92 and the connecting link 96 are urged toward the initial position (clockwise in FIG. 9) by the spring 98. Thus, when the ratchet 56 is disengaged from the latch 53, the latch 53 is rotated to the unlatched position by the spring force of the spring 98, and the slide door 14 is released from being held by the latch 53. The base bracket 52 is provided with a stopper block 99. When the latch 53 is in the unlatched position, the connecting link 96 contacts the stopper block 99 and the latch 53 is further unlatched (counterclockwise in FIG. 9). ) Is restricted.

  When the driving lever 92 rotates about the support shaft 93 in the counterclockwise direction in FIG. 9 from the initial position shown in FIG. 9 (position where the latch 53 becomes the unlatching position) by the pulling force of the closer cable 94, the latch 53 is moved to the driving lever. It is driven by 92 and rotates from the unlatched position toward the full latched position. At this time, the pin member 97 moves in an arc shape along an arc-shaped escape groove 52 a formed in the base bracket 52.

  Between the base bracket 52 of the door lock mechanism 51 and the cable entry / exit portion 48 c of the drive unit 31, an outer tube 101 formed by a flexible resin material is provided, and one end is connected to the drive lever 92. The closed cable 94 is inserted into the outer tube 101 and guided to the inside of the drum case 36.

  As shown in FIG. 13, the drive unit 31 is provided with a closer drum 102 as a closing rotator for driving the closer cable 94. The closer drum 102 is formed in a cylindrical shape, and is supported on the outer side of the boss portion 45a of the carrier 45 so as to be coaxial with and relative to the carrier 45 as shown in FIG.

  The closer cable 94 drawn into the drum case 36 from the cable entry / exit 48c is stretched over the outer periphery of the closer drum 102, and as shown in FIG. 13, at the cylindrical cable end 94a provided at the end thereof, the closer is closed. It is fixed to the drum 102. Accordingly, when the closer drum 102 rotates in the clockwise direction in FIG. 13, the closer cable 94 is wound around the closer drum 102 to operate.

  As shown in FIG. 13, on the outer periphery of the closer drum 102, a pair of driven convex portions 103a and 103b are provided that protrude outward in the radial direction and are symmetrically arranged 180 degrees around the axis. On the other hand, the cover 86 of the drum case 36 is provided with a pair of stopper portions 104a and 104b (shown with hatching in FIG. 13 for convenience) corresponding to the driven convex portions 103a and 103b. . When the closer drum 102 is in the initial position (the position shown in FIG. 13), the driven convex portions 103a and 103b are urged by the springs 98 to the corresponding stopper portions 104a and 104b in the counterclockwise direction in FIG. As a result, the rotation of the closer drum 102 in the counterclockwise direction in FIG. 13 is restricted. The carrier 45 is provided with a pair of driving convex portions 105a and 105b corresponding to the driven convex portions 103a and 103b. The carrier 45 is rotated by the rotation of the motor 32 with a speed reducer in the closing direction. Is rotated by a predetermined angle from the initial position (reference position) in the clockwise direction in FIG. 13, the driving convex portions 105 a and 105 b come into contact with the driven convex portions 103 a and 103 b of the closer drum 102, and the closer The drum 102 is driven by the carrier 45 and rotates together with the carrier 45. In other words, the closer cable 94 is connected to the latch 53 via the drive lever 92 and the connecting link 96 at one end thereof, and is connected to the carrier 45 via the closer drum 102 at the other end. The cable 94 can transmit the rotation of the carrier 45 to the latch 53.

  The closer drum 102 is biased by a spring 98 in a direction in which the closer cable 94 is pulled toward the initial position, that is, in a direction in which the latch 53 is rotated in the unlatched direction. The slack of 94 is prevented and the stability of the operation is enhanced.

  As shown in FIG. 9, in this opening / closing device 24, the connecting link 96 that connects the latch 53 and the drive lever 92 is configured as a toggle mechanism, and thus when the slide door 14 is closed to the half door position. The operation of the slide door 14 is made to function as a switching mechanism for switching from the automatic closing operation to the retracting operation by the closer mechanism 91.

  FIGS. 16A and 16B are explanatory diagrams showing a switching operation for switching the operation of the sliding door from the automatic closing operation to the retracting operation by the closer mechanism.

  When the slide door 14 is opened from the half door position and the latch 53 is in the unlatched position, as shown in FIG. 16A, the shaft of the pin member 97 that connects the latch 53 and the connecting link 96 is shown. The center is on the unlatch side (the latch 53 is connected to the center of rotation of the latch 53, that is, the axis L of the latch shaft 54 and the straight line L (virtual line) connecting the axis of the pin member 95 connecting the drive lever 92 and the connecting link 96. It is located on the side that rotates from the full latch position toward the unlatch position. As a result, even if the pulling force of the closer cable 94 is applied to the drive lever 92, the force is applied in a direction to further rotate the latch 53 in the unlatching direction via the connecting link 96. Is restricted. That is, when the slide door 14 is opened from the half-door position and the latch 53 is in the unlatched position, the pulling force of the closer cable 94, that is, the rotation of the carrier 45 (closer drum 102) causes the latch 53 to move toward the full latch direction. Rotation is regulated.

  On the other hand, when the opened slide door 14 is closed toward the fully closed position, the striker 58 enters the inside of the base bracket 52 and engages with the latch groove 53a of the latch 53, and the latch 53 pushes against the striker 58. Then, rotation is started from the unlatch position toward the full latch position against the spring force of the spring 98. As shown in FIG. 16B, the axis of the pin member 97 that connects the latch 53 and the connecting link 96 is more than the straight line L that connects the axis of the latch shaft 54 and the axis of the pin member 95. It moves to the full latch side (the side in which the latch 53 rotates from the unlatched position toward the full latched position). As a result, the rotation restriction of the latch 53 by the toggle mechanism, that is, the switching mechanism is released, and when the pulling force of the closer cable 94 is applied to the drive lever 92, the force is transmitted to the latch 53 via the connecting link 96 and latched. 53 rotates toward the full latch position. In this embodiment, the release position of the rotation restriction of the latch 53 by the switching mechanism is a position where the latch 53 reaches the half latch position, that is, the ratchet 56 is engaged with the half latch groove 53 b of the latch 53. Set to position.

  When the slide door 14 automatically opens from the fully closed position after the opening releaser mechanism 71 releases the holding of the slide door 14 to the fully closed position, as shown in FIG. The 45 driving convex portions 105 a and 105 b abut on the stopper portions 104 a and 104 b of the cover 86 through the driven convex portions 103 a and 103 b of the closer drum 102. As a result, the rotation of the carrier 45 in the counterclockwise direction in FIG. 14 is restrained, and the rotation of the output shaft 35 in the opening direction is transmitted to the drum 37 as shown in FIG. It will open. On the other hand, when the sliding door 14 is automatically closed from the fully open position after the release operation of the closing operation releaser mechanism 75 is released, as shown in FIG. The driving convex portions 105a and 105b of the carrier 45 abut on the driven convex portions 103a and 103b of the closer drum 102 in a state where the rotation is restricted by the cable 94. As a result, the rotation of the carrier 45 in the clockwise direction in FIG. 15 is restricted, and the rotation of the output shaft 35 in the closing direction is transmitted to the drum 37 as shown in FIG. 8B, and the slide door 14 is automatically closed. Will do.

  FIGS. 17A and 17B are explanatory diagrams showing the operation of the closer drum, respectively, and FIGS. 18A to 18C are explanatory diagrams showing driving states of the latches by the closer mechanism.

  When the carrier 45 is restrained and the rotation of the output shaft 35 is transmitted to the drum 37 and the slide door 14 is automatically closed and the slide door is closed to the half door position, the connection is made as shown in FIG. The operation restriction of the drive lever 92 by the link 96 is released. When the sliding door 14 reaches the half door position, the driving load of the drum 37 increases due to the reaction force of the door seal material 14a. Thereby, the rotation of the output shaft 35 of the motor 32 with speed reducer is transmitted to the carrier 45 as shown in FIG. 17A, and the carrier 45 starts to rotate in the clockwise direction in FIG. When the carrier 45 rotates, the driven convex portions 103a and 103b of the closer drum 102 are pushed by the driving convex portions 105a and 105b, and the closer drum 102 rotates in the clockwise direction in FIG.

  Here, the cover 86 is provided with an escape groove 106 that is continuous with the guide groove 88b and is shifted outward with respect to the axis of the guide groove 88b. When the closer drum 102 is rotated by the rotation of the carrier 45, the drive for closing operation is performed. The engagement protrusion 83a of the arm 83 is guided by the escape groove 106, and the engagement with the closing operation drive portion 89b of the carrier 45 is released. As a result, when the closer drum 102 is rotated, the engagement protrusion 83a is not drawn more than necessary by the closing operation drive portion 89b of the carrier 45.

  When the engagement between the carrier 45 and the engagement protrusion 83a is released, the closer drum 102 and the carrier 45 are covered with the cover 86 by the driven convex portions 103a and 103b of the closer drum 102 as shown in FIG. It is possible to rotate within a predetermined range in contact with the stopper portions 104a and 104b. When the closer drum 102 is rotated by the rotation of the carrier 45 and the closer cable 94 is driven, the pulling force of the closer cable 94 is transmitted to the latch 53 via the drive lever 92, as shown in FIG. The latch 53 engaged with the striker 58 in the half latch position is driven to the full latch position shown in FIG. 18C through the position shown in FIG. 18B, and the slide door 14 is pulled to the fully closed position. Will be. That is, when the slide door 14 is closed to the half door position, the latch 53 is driven by the carrier 45 and rotates in the full latch direction, and the slide door 14 is pulled to the fully closed position. The driving to the full latch position of the latch 53 by the rotation of the closer drum 102 is set to be completed until the driven convex portions 103a and 103b of the closer drum 102 come into contact with the stopper portions 104a and 104b of the cover 86. Has been.

  Thus, in this opening / closing device 24, when the slide door 14 is closed to the half door position, the latch 53 is driven to the full latch position by the motor 32 with a speed reducer for automatically opening and closing the slide door 14. The slide door 14 closed to the half door position can be pulled to the fully closed position. Therefore, the slide door 14 is automatically opened and closed by the single motor 32 with a reduction gear without providing another motor with a reduction gear to drive the closer mechanism, that is, the latch 53 to the fully latched position, and to the fully closed position. Pull-in operation can be performed. Thereby, this opening / closing device 24 can be reduced in size, and the mounting property to the vehicle body 12 can be improved.

  FIG. 19 is an explanatory view showing a modification of the switchgear shown in FIG. In FIG. 19, members corresponding to those described above are denoted by the same reference numerals.

  2, the lower rail 17 as a guide rail is fixed to the vehicle body 12, the lower arm 15 as a support arm is provided on the slide door 14, and the drive unit 31, the door lock mechanism 51, and the fully open hook mechanism 61 are provided. It is arranged inside the slide door 14. On the other hand, in the modification shown in FIG. 19, the drive unit 31, the door lock mechanism 51, and the fully open hook mechanism 61 are arranged on the vehicle body 12 on the same side as the lower rail 17.

  In this case, reversing pulleys 107a and 107b are provided at both ends in the longitudinal direction of the lower rail 17, respectively, and the opening side cable 25a drawn from the drive unit 31 is reversed in its moving direction by the reversing pulley 107a, and its tip is at the lower rail. 17 is connected to the lower arm 15 from the open side (rear side of the vehicle) along the line 17, and the closing cable 25 b is reversed in its moving direction by the reversing pulley 107 b, and its tip is from the closed side (front side of the vehicle) along the lower rail 17. It is connected to the lower arm 15. In this case, the striker 58 that engages with the latch 53 of the door lock mechanism 51 is fixed to the slide door 14.

  20 is a front view showing a modification of the closer mechanism shown in FIG.

  In the closer mechanism 91 shown in FIG. 9, one end of the connection link 96 is rotatably connected to the drive lever 92 by the pin member 95, thereby transmitting the driving force of the drive lever 92 to the connection link 96. On the other hand, in the modified example shown in FIG. 20, the drive lever 92 is provided with an arc-shaped long hole 110 centered on the support shaft 93, and the pin member 95 attached to one end of the connecting link 96 is connected to the long hole 110. The drive lever 92 is supported so as to be movable along the elongated hole 110. Thereby, even when the drive lever 92 is in the initial position (position shown in FIG. 20), the pin member 95 moves through the elongated hole 110, so that the latch 53 does not interlock with the drive lever 92 and is in the unlatched position and the full latch position. It can be rotated between and.

  A spring 111 is mounted on the support shaft 93, and the drive lever 92 is biased toward the initial position (clockwise in FIG. 9) by the spring 111. The latch 53 is always biased toward the unlatched position by a return spring (not shown) provided on the latch shaft 54, and the pin member 95 of the connecting link 96 connected to the latch 53 is also unlatched end 110a of the elongated hole 110. The pin member 95 is arranged at the unlatched end 110a of the long hole 110 in the initial state (the state shown in FIG. 20).

  21A to 21D are explanatory views showing the operation of the closer mechanism shown in FIG.

  When the slide door 14 is opened from the half door position and the latch 53 is in the unlatched position, as shown in FIG. 21A, the shaft of the pin member 97 that connects the latch 53 and the connecting link 96 is shown. The center is on the unlatch side with respect to the straight line L, and the rotation of the latch 53 in the full latch direction by the pulling force of the closer cable 94 is restricted as in the case shown in FIG.

  When the slide door 14 is closed from this state toward the fully closed position, the latch 53 is pushed by the striker 58 and rotates from the unlatched position toward the fully latched position. As shown in FIG. The shaft center of the member 97 moves to the full latch side with respect to the straight line L, and the rotation restriction of the latch 53 by the toggle mechanism, that is, the switching mechanism is released as in the case shown in FIG.

  At this time, since the drive lever 92 is connected to the pin member 95 in the long hole 110, the speed at which the slide door 14 is closed, that is, the entry speed of the striker 58 with respect to the latch 53 is high. Even when the pin member 95 of the connection link 96 starts moving earlier, the pin member 95 moves along the long hole 110 toward the full latch end 110 b of the long hole 110, and the closer cable 94 is connected to the closer cable 94. There is no slack. Therefore, the closer mechanism 91 can be operated reliably.

  When the rotation restriction of the latch 53 by the toggle mechanism is released, the drive lever 92 is rotated by the pulling force of the closer cable 94, and the pin member 95 is driven by the drive lever 92 at the unlatched end of the long hole 110. Thereby, as shown in FIG. 21C, the latch 53 rotates to the full latch position.

  When the latch 53 rotates to the full latch position and the electromagnetic clutch (not shown) of the drive unit 31 is switched to the power cut-off state, the closer drum 102 is free to rotate, and as shown in FIG. The spring 111 is urged by the spring force to return to the initial position while pulling the closer cable 94. At this time, the latch 53 and the connection link 96 are maintained in a fully latched state. However, since the pin member 95 is connected to the drive lever 92 in the long hole 110, the drive lever can be operated without dragging the connection link 96 or the pin member 95. 92 can be returned smoothly. After the drive lever 92 returns, the pin member 95 is disposed at the full latch end 110b of the long hole 110.

  On the other hand, while the sliding door 14 is held in the fully closed position by the door lock mechanism 51, the opening side of an opening / closing switch (not shown) is operated, and the release action releaser mechanism 71 engages the latchet 56 with the latch 53. When automatically released, the pin member 95 is urged by a return spring (not shown) and moves to the unlatched end 110a of the elongated hole 110 along the elongated hole 110 of the drive lever 92 in the initial position, thereby The latch 53 rotates from the full latch position to the unlatched position and returns to the initial position shown in FIG.

  22 is a sectional view showing a modification in which a differential gear mechanism is used as a speed reduction mechanism in place of the planetary gear mechanism shown in FIGS. 5 and 6. FIG. 23 is an exploded perspective view of the differential gear mechanism shown in FIG. FIG.

  In the case shown in FIGS. 5 and 6, the planetary gear mechanism 41 is used as a speed reducing mechanism for transmitting the rotation of the output shaft 35 to the drum 37. On the other hand, in the modification shown in FIGS. 22 and 23, a differential gear mechanism 121 (differential gear mechanism) is used as the speed reduction mechanism.

  The differential gear mechanism 121 includes a drive-side bevel gear 122 as an input gear. The drive-side bevel gear 122 is engaged and fixed to an output shaft 35 provided with a serration, and rotates together with the output shaft 35. ing.

  A driven-side bevel gear 123 as an output gear is provided on the back side of the end surface in the axial direction of the drum 37. The driven-side bevel gear 123 is fitted and fixed to the inner periphery of the drum 37 at its base, and rotates together with the drum 37. The driven side bevel gear 123 is arranged coaxially with the output shaft 35 and faces the drive side bevel gear 122 in the axial direction so that the tooth portions face each other.

  A support member 124 is accommodated coaxially with the drum 37 inside the drum 37. A connecting hole 124 a that opens toward the output shaft 35 is formed in the shaft center of the support member 124, while a cylindrical guide portion 125 that extends along the axial direction is integrally formed at the tip of the output shaft 35. The guide member 125 is inserted into the connecting hole 124a, so that the support member 124 is supported by the guide portion 125 and is connected to the output shaft 35 so as to be relatively rotatable.

  A pair of support shafts 126 orthogonal to the output shaft 35, that is, projecting radially outward from the outer periphery, are integrally formed on the outer periphery of the support member 124 so as to be coaxial with each other and at a substantially central portion in the axial direction of the drum 37. Is provided. Each support shaft 126 is equipped with a side bevel gear 127 as a switching gear. These side-side bevel gears 127 are rotatably supported by the corresponding support shafts 126, and are disposed between the drive-side bevel gear 122 and the driven-side bevel gear 123, respectively, and meshed with the bevel gears 122, 123. .

  The tip of the support member 124 opposite to the side where the connection hole 124a is provided passes through the axis of the driven bevel gear 123 and protrudes outside the drum 37. The tip is provided with serrations and has a small diameter. The carrier 45 is fixed by engaging the carrier 45 with the serration and screwing the nut 129 into the fixing screw portion 128. That is, the side bevel gear 127 is rotatably supported by the carrier 45 via the support member 124, and can rotate about the axis of the output shaft 35 together with the carrier 45. The driven bevel gear 123 is rotatable relative to the support member 124.

  With such a structure, when the slide door 14 is held in the fully closed position or the fully open position by the door lock mechanism 51 or the fully open hook mechanism 61, the drum 37 connected to the slide door 14 via the cables 25a and 25b. At the same time, the rotation of the driven bevel gear 123 is constrained, and when the motor 32 with a reduction gear is operated, the rotation of the output shaft 35, that is, the drive side bevel gear 122, is transmitted via the side bevel gear 127 and the carrier 45, that is, the differential gear mechanism 121. Is transmitted to the releaser drive mechanism 81. At this time, due to the function of the differential gear mechanism 121, the rotation of the output shaft 35 is reduced to ½, and the output torque is doubled and transmitted to the releaser drive mechanism 81. Similarly, when the automatic closing operation of the slide door 14 is switched to the retracting operation by the closer mechanism 91, the rotation of the output shaft 35 is transmitted to the closer mechanism 91 via the differential gear mechanism 121. At this time, due to the function of the differential gear mechanism 121, the rotation of the output shaft 35 is reduced to ½, and the output torque is doubled and transmitted to the closer mechanism 91. The output of 32 can be reduced. On the other hand, when the sliding door 14 automatically opens and closes, rotation about the output shaft 35 of the carrier 45, that is, the side-side bevel gear 127, is restricted, whereby the rotation of the output shaft 35, that is, the drive-side bevel gear 122 is controlled on the side side. The drum 37 is rotated by being transmitted to the driven side bevel gear 123 through the bevel gear 127. At this time, the rotation of the output shaft 35 is transmitted to the drum 37 at 1: 1 by the function of the differential gear mechanism 121.
