It is like that.

  The lock mechanism 32a is provided with a closer mechanism 51 for automatically pulling the slide door 14 closed to the half door position to the fully closed position against the elastic force of the door seal member 14a.

  The closer mechanism 51 includes a closer cable 52. A cylindrical cable end 52a is fixed to the end of the closer cable 52, and one end of a cable link 53 is rotatably connected to the cable end 52a. . As shown in FIG. 3, a bracket 54 for supporting a latch shaft 42 and a ratchet shaft 44 is fixed to the base bracket 41, and the bracket 54 is fixed to the vertical direction of the vehicle 11 (to the lock mechanism portion 32a of the striker 33a). A guide groove 54a that extends linearly in a direction perpendicular to the intrusion direction is provided. One end of the cable end 52a connected to the cable link 53 protrudes in the axial direction from the outer surface of the cable link 53, and the protruding portion is movably engaged with the guide groove 54a. Thereby, the cable link 53 is linearly reciprocable along the guide groove 54a. Further, the cable link 53 is biased upward toward the original position (position shown in FIG. 2) by a close plate 55 described later.

  A close plate 55 is attached to the latch shaft 42. The close plate 55 is formed of a steel plate in a substantially fan shape having an arc-shaped outer peripheral edge 55a, and is disposed so as to overlap the latch 43. The main plate is latched so as to be rotatable relative to the latch 43. The shaft 42 is rotatably supported. The close plate 55 is urged counterclockwise in FIG. 2 toward the original position (position shown in FIG. 2) by a return spring (not shown).

  One end of a close link 57 is rotatably connected to the other end of the cable link 53 by a pin member 56. The close link 57 is disposed so as to overlap the close plate 55, and the other end is rotatably supported by the latch shaft 42 so as to be rotatable relative to the latch 43. Further, a drive piece 57a that protrudes in the axial direction toward the close plate 55 is fixed to an intermediate portion of the close link 57, and this drive piece 57a contacts the circumferential end face of the close plate 55 from the circumferential direction. It is like that.

  When the cable link 53 is pulled by the closer cable 52 and moves downward in the drawing along the guide groove 54a, the linear motion is converted into a rotational motion around the latch shaft 42 by the close link 57, and the close link 57 is latched. It rotates about the shaft 42. Thereby, the close plate 55 is pushed by the drive piece 57a and rotates in the full latch direction of the latch 43 (clockwise direction in FIG. 2).

  In order to transmit the rotation of the close plate 55 to the latch 43, the latch 43 is provided with a latch pin 58. As shown in FIG. 3, the latch 43 is provided with an arm portion 59 having a guide groove 59a extending in the radial direction of the latch shaft 42, and the latch pin 58 is mounted in the guide groove 59a.

It is like that. Further, the stroke end on the radially inner side (on the latch shaft 42 side) of the guide groove 59a is an operating position, and the latch pin 58 in the operating position is positioned on the track of the driving side 55b facing the circumferential direction of the close plate 55. Thus, it can come into contact with the close plate 55.

  In order to move the latch pin 58 from the operating position to the cancel position, a cancel link 61 is provided in the lock mechanism portion 32a. The cancel link 61 is formed into a shape that is bent in an arc shape by a steel plate, and includes an arc-shaped guide groove 61a extending along the shape, and the latch pin 58 engages with the guide groove 61a to form the guide groove 61a. It is free to move along. The cancel link 61 is attached to a support shaft 62 that is fixed to the base bracket 41 in parallel with the latch shaft 42 at one end thereof, and is swingable about the support shaft 62. Then, the cancel link 61 is rotated in the direction away from the latch shaft 42 (clockwise direction in FIG. 2) around the support shaft 62, that is, the cancel link 61 is cancelled. Can be moved to the cancel position.

  When the cancel link 61 is at the position where the latch pin 58 is in the operating position, the guide groove 61a has an arc shape centered on the latch shaft 42, and the latch pin 58 is on the track of the drive side 55b of the close plate 55 by the guide groove 61a. Will be guided.

  The cancel link 61 is always urged by a return spring (not shown) in a direction (the counterclockwise direction in FIG. 2) in which the latch pin 58 is in the operating position. Thereby, when the slide door 14 is in the open state, that is, when the latch 43 is in the unlatched position, the latch pin 58 in the cancel position is on the outer peripheral edge 55a of the close plate 55 as shown in FIG. Is pressed against the outer peripheral edge 55a. When the slide door 14 is closed to the half door position, that is, when the latch 43 is rotated to the half latch position, the latch pin 58 moves to the circumferential end of the close plate 55 and is pushed by the cancel link 61. Thus, it moves from the cancel position to the operating position, that is, from the position on the outer peripheral edge 55a of the close plate 55 to the position facing the drive side 55b.

  The lock mechanism portion 32a is provided with a releaser mechanism 63 for automatically holding the slide door 14 in the fully closed position (door lock) by the door lock device 31, that is, automatically releasing the engagement of the ratchet 45 with the latch 43. ing.

  The releaser mechanism 63 includes a releaser link 64 that is attached to the ratchet shaft 44 so as to overlap the ratchet 45 in the axial direction. The releaser link 64 is formed by bending a steel plate and is supported by the ratchet shaft 44 so as to be swingable. A cable end 65 a of a releaser cable 65 is rotatably connected to the releaser link 64. When the releaser cable 65 is pulled, the releaser link 64 rotates about the ratchet shaft 44 in the counterclockwise direction in FIG. It is supposed to be.

  The releaser link 64 is provided with a drive claw 64a protruding toward the ratchet 45. When the releaser cable 65 is pulled and the releaser link 64 rotates, the ratchet 45 is pushed by the drive claw 64a and engages with the latch 43. It rotates in the counterclockwise direction in FIG. 2 from the mating position toward the release position where the engagement with the latch 43 is released.

  The releaser link 64 is provided with a drive arm portion 64b protruding toward the cancel link 61, while the cancel link 61 is provided with a driven arm portion 61b protruding in the radial direction of the support shaft 62. When the releaser cable 65 is pulled and the releaser link 64 rotates, the driven arm portion 61b is pushed by the drive arm portion 64b, and the cancel link 61 moves in a direction to move the latch pin 58 from the operating position toward the cancel position. It is supposed to be. That is, when the releaser cable 65 is pulled, the cancel link 61 performs a cancel operation.

  As described above, when the releaser cable 65 is pulled, the releaser link 64 drives the ratchet 45 to move to the release position, and the door lock device 31 holds the slide door 14 in the fully closed position (door lock). In addition, the cancel link 61 performs a cancel operation.

  A releaser side drive arm 87 is disposed between the releaser side drive cam 85 inside the gear case 72a and the inner surface of the gear case 72a. The releaser side drive arm 87 is formed of a steel plate in a straight line shape, and is fixed to the first support shaft 78 at one end thereof. As a result, the releaser side drive arm 87 is connected to the releaser side spool 86 disposed outside the gear case 72 a via the first support shaft 78, and rotates together with the releaser side spool 86.

  A mounting groove 87a extending along the radial direction of the first support shaft 78 is formed in the releaser side driving arm 87, and a releaser side driving pin 88 is mounted in the mounting groove 87a. The releaser-side drive pin 88 is movable in the radial direction of the first support shaft 78 along the mounting groove 87a, and the spring 89 mounted between the first support shaft 78 and the inside of the mounting groove 87a. Is always urged toward the stroke end, that is, the first support shaft 78 side. Further, both ends of the releaser side drive pin 88 protrude from the front and back sides of the releaser side drive arm 87, and the portion protruding to the back side (first reduction gear 77 side) is urged to the outer periphery of the releaser side drive cam 85. It is in elastic contact with the state. Thus, when the electric motor 71 rotates in the forward direction, the releaser side drive pin 88 is positioned at the stroke end inside the mounting groove 87a and engages with the releaser side drive surface 85a of the releaser side drive cam 85, so that the cam 85 Driven to rotate about the first support shaft 78. That is, when the electric motor 71 rotates in the forward direction, the releaser side drive pin 88 engages with the releaser side drive surface 85a, and the rotation of the cam 85 is released via the releaser side drive pin 88 and the releaser side drive arm 87. It is transmitted to the side spool 86. On the other hand, when the electric motor 71 rotates in the reverse direction, the releaser side drive pin 88 is in sliding contact with the releaser side idle running surface 85b and guided along the idle running surface 85b. Thereby, when the electric motor 71 rotates in the reverse direction, the releaser side drive pin 88 does not engage with the releaser side drive surface 85a, and the cam 85 rotates idly.

  In order to hold the releaser-side spool 86 in the original position, a releaser-side original position rib 91 is provided on the inner surface of the gear case 72a. The releaser-side original position rib 91 is formed in a rib shape that protrudes from the inner surface of the gear case 72a toward the releaser-side drive arm 87 and extends in a circumferential direction, that is, a direction orthogonal to the moving direction of the releaser-side drive pin 88. In the illustrated case, it is formed integrally with the gear case 72a. When the releaser-side spool 86 is in the original position, the releaser-side drive pin 88 contacts the releaser-side original position rib 91 from the circumferential direction, so that the releaser-side spool 86 exceeds the original position due to the tension from the releaser cable 65. Without being moved.

  Further, when the releaser-side drive pin 88 is driven by the releaser-side drive cam 85, the releaser-side drive pin 88 engages with the releaser-side drive cam 85 when the releaser-side spool 86 rotates a predetermined angle from the original position. In order to automatically release, a releaser side release rib 92 is provided on the inner surface of the gear case 72a. The releaser side release rib 92 protrudes from the inner surface of the gear case 72a toward the releaser side drive arm 87 and is formed in a rib shape extending obliquely with respect to the radial direction of the first support shaft 78. In this case, it is formed integrally with the gear case 72a. Here, the inclination direction of the releaser-side release rib 92 is set to a direction shifted toward the direction in which the releaser-side drive cam 85 rotates when the electric motor 71 rotates forward toward the outer peripheral side. When the releaser-side spool 86 rotates by a predetermined angle from the original position, the releaser-side drive pin 88 engaged with and driven by the releaser-side drive surface 85a comes into contact with the releaser-side release rib 92 and is guided by the rib 92 to be attached to the mounting groove 87a. And the engagement with the releaser side drive surface 85a is released. That is, when the releaser-side spool 86 rotates by a predetermined angle from the original position, the releaser-side drive pin 88 is guided by the releaser-side release rib 92 and moves from the releaser-side drive surface 85a to the releaser-side idle running surface 85b. And the releaser side drive surface 85a are disengaged. Thereby, the releaser side spool 86 is urged toward the original position by the tension of the releaser cable 65, and returns to the original position.

  The closer drive mechanism 84 includes a closer drive cam 95 provided on the end face of the second reduction gear 82. The closer drive cam 95 is smooth on the closer drive surface 95a perpendicular to the circumferential direction around the second support shaft 81, that is, along the radial direction of the second support shaft 81, and on the inner and outer ends of the closer drive surface 95a. And a closed closer-side idle running surface 95b that is formed integrally with the second reduction gear 82 and rotates together with the second reduction gear 82. Note that the closer-side drive surface 95a is directed in the direction of advancing when the electric motor 71 is reversed, contrary to the releaser-side drive surface 85a.

  A closer side spool 96 as a closer side operating member is fixed to a tip end portion of the second support shaft 81 protruding from the gear case 72a. The closer-side spool 96 is formed in a substantially semicircular shape, and is fixed to the second support shaft 81 so that it is coaxially and relatively rotated with respect to the second reduction gear 82 that is supported by the second support shaft 81 so as to be relatively rotatable. It is free. As shown in FIG. 4, the closer spool 96 is disposed on the outer surface of the gear case 72a, and the closer cable 52 is connected to a connecting portion 96a provided at one end in the circumferential direction. When the closer-side spool 96 rotates counterclockwise in the drawing from the original position shown in FIG. 5, the closer cable 52 is wound around the spool 96, whereby the cable link 53 is pulled by the closer cable 52 and latches 43. Rotates from the unlatched position toward the fully latched position.

  Note that the closer-side spool 96 is always in FIG. 5 by transmitting the spring force of a return spring (not shown) for urging the closing plate 55 to the original position via the closing link 57, the cable link 53, and the closing cable 52. Is biased in the circumferential direction toward the original position shown in FIG.

  A closer drive arm 97 is disposed between the closer drive cam 95 inside the gear case 72a and the inner surface of the gear case 72a. The closer drive arm 97 is formed of a steel plate in a straight line, and is fixed to the second support shaft 81 at one end thereof. Accordingly, the closer drive arm 97 is connected to the closer spool 96 disposed outside the gear case 72 a via the second support shaft 81, and rotates together with the closer spool 96.

  A mounting groove 97a extending along the radial direction of the second support shaft 81 is formed in the closer driving arm 97, and a closer driving pin 98 is mounted in the mounting groove 97a. The closer-side drive pin 98 is movable in the radial direction of the second support shaft 81 along the mounting groove 97a, and the spring 99 mounted between the second support shaft 81 and the inside of the mounting groove 97a. Is always urged toward the stroke end, that is, the second support shaft 81 side. Further, both ends of the closer drive pin 98 protrude to the front and back of the closer drive arm 97, and the portion protruding to the back side (second reduction gear 82 side) is biased to the outer periphery of the closer drive cam 95. It is in elastic contact with the state. As a result, when the electric motor 71 rotates in the reverse direction, the closer drive pin 98 is positioned at the inner stroke end of the mounting groove 97 a and engages with the closer drive surface 95 a of the closer drive cam 95 to drive the cam 95. Then, the second spindle 81 is rotated as a center. That is, when the electric motor 71 rotates in the reverse direction, the closer drive pin 98 is engaged with the closer drive surface 95a, and the rotation of the cam 95 is performed on the closer side via the closer drive pin 98 and the closer drive arm 97. It is transmitted to the spool 96. On the contrary, when the electric motor 71 rotates in the forward direction, the closer-side drive pin 98 comes into sliding contact with the closer-side idle running surface 95b and is guided along the idle running surface 95b. Thereby, when the electric motor 71 rotates forward, the closer drive pin 98 does not engage with the closer drive surface 95a, and the cam 95 rotates idly.

  In order to hold the closer side spool 96 in the original position, a closer side original position rib 101 is provided on the inner surface of the gear case 72a. The closer side original position rib 101 protrudes from the inner surface of the gear case 72a toward the closer side driving arm 97 and is formed in a rib shape extending in the circumferential direction, that is, in the direction perpendicular to the moving direction of the closer side driving pin 98. Like the releaser side original position rib 91, the gear case 72a is integrally formed. When the closer-side spool 96 is in the original position, the closer-side drive pin 98 abuts against the closer-side original position rib 101 from the circumferential direction, so that the closer-side spool 96 exceeds the original position due to the tension from the closer cable 52. Without being moved.

  Further, when the closer side driving pin 98 is driven by the closer side driving cam 95, the closer side driving pin 98 is engaged with the closer side driving cam 95 when the closer side spool 96 is rotated by a predetermined angle from the original position. In order to automatically cancel, the closer side release rib 102 is provided on the inner surface of the gear case 72a. The closer-side release rib 102 protrudes from the inner surface of the gear case 72a toward the closer-side driving arm 97 and is formed in a rib shape extending obliquely with respect to the radial direction of the second support shaft 81. Like the side release rib 92, it is formed integrally with the gear case 72a. Here, the inclination direction of the closer-side release rib 102 is set to a direction shifted toward the direction in which the closer-side drive cam 95 rotates when the electric motor 71 reverses toward the outer peripheral side. When the closer-side spool 96 is rotated by a predetermined angle from the original position, the closer-side driving pin 98 engaged with and driven by the closer-side driving surface 95a comes into contact with the closer-side release rib 102 and is guided by the rib 102 to be attached to the mounting groove 97a. And the engagement with the closer-side drive surface 95a is released. That is, when the closer spool 96 is rotated by a predetermined angle from the original position, the closer drive pin 98 is guided by the closer release rib 102 and moved from the closer drive surface 95a to the closer idle running surface 95b. And the closer drive surface 95a are disengaged. As a result, the closer spool 96 is urged toward the original position by the tension of the closer cable 52 and returns to the original position.

  Outer tubes 103a and 103b are connected between the actuator unit 34 and the lock mechanism portion 32a, and the closer cable 52 and the releaser cable 65 are inserted into the corresponding outer tubes 103a and 103b, respectively, and the outer tubes 103a and 103b. To move along.

  FIGS. 6A to 6C are explanatory diagrams showing the operation of the releaser mechanism, and FIGS. 7A to 7D are explanatory diagrams showing the operation of the releaser driving mechanism.

  Next, operations of the releaser mechanism 63 and the releaser drive mechanism 83 will be described with reference to FIGS.

  In this door lock device 31, the releaser mechanism 63 is driven by the releaser drive mechanism 83 by rotating the electric motor 71 of the actuator unit 34 in the forward direction, and the sliding door by the engagement of the ratchet 45 to the latch 43, that is, the lock mechanism portion 32a. 14 can be automatically released from being held in the fully closed position.

  When the slide door 14 is in the fully closed position, as shown in FIG. 6A, the latch 43 is in the full latch position, the ratchet 45 is engaged with the latch 43, and the latch 43 is held in the full latch position. . As shown in FIG. 7A, the releaser-side spool 86 is in its original position, and the releaser-side drive pin 88 is in contact with the releaser-side drive surface 85a of the releaser-side drive cam 85. From this state, when the slide door 14 is automatically opened by the automatic opening / closing device 21, the electric motor 71 of the actuator unit 34 rotates forward, and the releaser mechanism 63 is released in advance by the releaser drive mechanism 83, Next, the engagement between the latch mechanism 32b of the slide door 14 and the striker 33b is released.

  That is, when the electric motor 71 rotates in the forward direction, as shown in FIG. 7B, the releaser side drive cam 85 rotates together with the first reduction gear 77, and the rotation of the cam 85 is released via the releaser side drive pin 88. It is transmitted to the side drive arm 87, that is, the releaser side spool 86, and the releaser cable 65 is pulled by the releaser side spool 86. When the releaser cable 65 is pulled by the releaser side spool 86, as shown in FIG. 6B, the releaser link 64 is operated and the ratchet 45 is rotated in the counterclockwise direction in FIG. The engagement of the ratchet 45 with the latch 43 is released. When the releaser cable 65 is pulled, the cancel link 61 is canceled as shown in FIG. 6B, and the latch pin 58 is driven from the operating position to the cancel position. As a result, as shown in FIG. 6C, the latch 43 is rotated to the unlatched position by the spring force of the return spring (not shown), and the striker 33 a is released from the latch 43. When the striker 33a is released from the latch 43, the holding of the slide door 14 to the fully closed position by the lock mechanism 32a is released, and the slide door 14 is automatically driven toward the fully open position by being driven by the automatic opening / closing device 21. It can be opened.

  On the other hand, when the releaser-side spool 86 rotates from the original position to the predetermined position, the releaser-side drive pin 88 comes into contact with the releaser-side release rib 92 and is guided by the rib 92 as shown in FIG. 7C. The side drive pin 88 moves radially outward along the mounting groove 87a. As a result, the releaser-side drive pin 88 is disengaged from the releaser-side drive surface 85a, and the releaser-side spool 86 moves toward the original position due to the tension of the releaser cable 65, as shown in FIG. 7 (d). The releaser-side drive pin 88 comes into contact with the releaser-side original position rib 91 to stop at the original position. When the releaser-side spool 86 moves toward the original position, as shown in FIG. 6C, the releaser link 64 is urged by a return spring (not shown) to return to the original position.

  In addition, when the releaser drive mechanism 83 is operating due to the normal rotation of the electric motor 71, the closer drive pin 98 does not slide in contact with the closer idle running surface 95b and engage with the closer drive surface 95a. The closer drive mechanism 84 is in a state in which the closer-side drive cam 95 is idle, and the closer mechanism 51 does not operate.

  8A to 8D are explanatory diagrams showing the operation of the closer mechanism, and FIGS. 9A to 9D are explanatory diagrams showing the operation of the closer driving mechanism.

  Next, operations of the closer mechanism 51 and the closer driving mechanism 84 will be described with reference to FIGS.

  In the door lock device 31, the electric motor 71 of the actuator unit 34 is reversed to drive the closer mechanism 51 by the closer driving mechanism 84, and the latch 43 engaged with the striker 33 a is rotated to the full latch position to slide the door. 14 can be reliably pulled to the fully closed position against the elastic force of the door seal material 14a.

  When the slide door 14 is opened, the latch 43 is in the unlatched position, the close plate 55 is in the original position, and the latch pin 58 is in the cancel position, as shown in FIG. Is in contact with the outer peripheral edge 55a. 9A, the closer-side spool 96 is in the original position, and the closer-side driving pin 98 is in contact with the closer-side driving surface 95a of the closer-side driving cam 95.

  When the slide door 14 is closed to a predetermined opening from this state, first, the latch mechanism 32b of the slide door 14 and the striker 33b are engaged, and the end portion of the slide door 14 on the vehicle front side is held by the vehicle body 12. Next, the striker 33 a that has entered the lock mechanism portion 32 a engages with the latch groove 43 a of the latch 43.

  When the slide door 14 is closed to the half door position, the latch 43 rotates to the half latch position as shown in FIG. 8B, and the latch pin 58 reaches the circumferential end of the close plate 55. Then, the latch pin 58 is pushed by the cancel link 61, moves from the cancel position on the outer peripheral edge 55a of the close plate 55 to the operating position, and opposes the drive side 55b. Further, the ratchet 45 is engaged with the half latch locking groove 43b of the latch 43, and the rotation of the latch 43 in the unlatching direction is restricted, and the latch 43 is held at the half latch position.

  When the latch 43 rotates from the unlatched position to the half-latched position, the electric motor 71 of the actuator unit 34 starts to operate in the reverse direction, and the closer-side drive pin 98 is pushed by the closer-side drive surface 95a to rotate the closer-side spool 96. To do. When the closer spool 96 is rotated, the cable link 53 is moved downward in the drawing as shown in FIG. 8C, and the closing plate 55 is rotated. When the close plate 55 rotates, the latch pin 58 on the track of the close plate 55 is pushed by the drive side 55b of the close plate 55, and the latch 43 rotates from the half latch position toward the full latch position. As a result, the slide door 14 is pulled from the half door position toward the fully closed position by the power of the actuator unit 34.

  The actuator unit 34 is activated by a half latch switch (not shown) for detecting that the latch 43 is in the half latch position, a ratchet switch (not shown) for detecting that the ratchet 45 is engaged with the latch 43, or the like. The timing is based on the detection signal.

  When the latch 43 is rotationally driven from the half latch position to the full latch position by the actuator unit 34, the slide door 14 is fully closed, and the ratchet 45 is formed in the full latch locking groove 43c of the latch 43 as shown in FIG. And the latch 43 is held in the full latch position. As a result, the slide door 14 is held in a fully closed state.

  On the other hand, when the closer spool 96 rotates from the original position to the predetermined position, the closer drive pin 98 abuts on the closer release rib 102 and is guided by the rib 102 as shown in FIG. 9C. The side drive pin 98 moves radially outward along the mounting groove 97a. As a result, the closer-side drive pin 98 is disengaged from the closer-side drive surface 95a, and the closer-side spool 96 is moved toward the original position by the tension of the closer cable 52, as shown in FIG. 9 (d). The closer-side drive pin 98 comes into contact with the closer-side original position rib 101 to stop at the original position. When the closer spool 96 returns to the original position, the cable link 53 and the closing plate 55 are urged by a return spring (not shown) to return to the original position, and the door lock device 31 reaches the fully closed position of the slide door 14. The pull-in operation is completed.

  In addition, when the closer drive mechanism 84 is operating by the reverse rotation of the electric motor 71, the releaser-side drive pin 88 does not slidably contact the releaser-side idle running surface 85b and engage with the releaser-side drive surface 85a. In the drive mechanism 83, the releaser side drive cam 85 is idled, and the releaser mechanism 63 does not operate.

  As described above, in the door lock device 31, the releaser mechanism 63 can be operated by the normal rotation of the electric motor 71 and the closer mechanism 51 can be operated by the reverse rotation of the electric motor 71. The door lock device 31 can be reduced in size and weight as a structure for operating both the 63 and the closer mechanism 51.

  Further, in the door lock device 31, when the operation of the releaser mechanism 63 by the normal rotation of the electric motor 71 is completed, the releaser side drive pin 88 is disengaged from the releaser side drive cam 85, and the releaser side spool 86 is released. When the operation of the closer mechanism 51 by the reverse rotation of the electric motor 71 is completed quickly, the closer-side driving pin 98 is disengaged from the closer-side driving cam 95 and the closer-side spool 96 is quickly moved. Since it returns to the original position, the operation of the other can be started quickly after the operation of one of the releaser mechanism 63 or the closer mechanism 51. Thereby, the operation | movement of this door lock apparatus 31 can be advanced, and the operativity can be improved.

  When the open side of the open / close switch of the automatic opening / closing device 21 is operated in a state where the slide door 14 is pulled from the half door position toward the fully closed position by the actuator unit 34, the releaser drive mechanism 83 The releaser link 64 is rotated by the operation, and the engagement of the ratchet 45 with the latch 43 is released. Further, the cancel link 61 is canceled by the operation of the releaser driving mechanism 83, the latch pin 58 is driven from the operating position to the cancel position, and the engagement of the latch pin 58 with the drive side 55b of the close plate 55 is released. As a result, the latch 43 can be moved in the unlatching direction, and the power transmission path from the close plate 55 to the latch 43 via the latch pin 58 is interrupted, so that the pull-in operation is canceled and the striker 33a from the latch 43 is cancelled. Can be opened. As a result, the sliding door 14 can be automatically opened by the automatic opening / closing device 21.
