As described above, the locking block 65 protrudes laterally (a direction substantially orthogonal to the axial direction of the center rail 18 and in a horizontal direction).

  Here, since the holder 55 provided in the connecting unit 53 is biased in a direction away from the retracting portion 54a by the spring 56, the main body portion 62a of the latch 62 connected to the holder 55 via the closing cable 52 is The spring 56 is pressed against the locking surface 65 a of the locking block 65 by the spring force, that is, the tension of the closing cable 52. That is, the locking surface 65a is formed in a concave curved surface that matches the shape of the latch 62, and when the latch 62 is locked, the closing cable 52 is routed in a direction crossing the locking surface 65a. Therefore, the latch 62 is securely supported by the locking surface 65a by the tension of the closing cable 52. As a result, the latch 62 is in the locked state in which the movement toward the closing side along the center rail 18 is restricted by the locking block 65, and the holder 55 connected to the latch 62 via the closing cable 52, that is, the moving state. The pulley is held in the initial position shown in FIG.

  The locking block 65 is provided with a relief groove 65b that opens on the side facing the vehicle body and extends along the axial direction of the center rail 18. When the latch 62 is locked, the closing cable 52 is It is guided to the guide pulley 63 through the escape groove 65b.

  On the other hand, as shown in FIGS. 6 and 9, the roller assembly 22 (center arm 16) supported movably on the center rail 18 is released from the latched state by the latch block 65 from the latched state. In order to drive to the release state, a drive unit 71 is provided.

  The roller assembly 22 includes a main body bracket 74 that rotatably supports a pair of guide rollers 72 guided by the center rail 18 and a traveling roller 73 that travels on the center rail 18. It is formed integrally with the main body bracket 74 at a portion shifted to the closed side (side closer to the closed end of the center rail 18) with respect to the rollers 72 and 73. Further, the drive unit 71 has a cylindrical shape with the axial direction directed in the vehicle vertical direction, and is disposed so as to pass through a position offset to the side of the locking block 65 as shown in FIG. The connecting leg 62b of the latch 62 is positioned on the moving path.

  When the sliding door 14 is closed to the half door position, the drive unit 71 contacts the connecting leg 62b of the latch 62, pushes the connecting leg 62b in the closing direction, and the latch 62 is supported at the corner of the locking block 65. Rotate as As a result, as shown in FIG. 9, the latch 62 is driven by the drive unit 71 to be in a released state in which the axial direction thereof is in the direction along the axial direction of the center rail 18. Thereafter, when the door seal member 14a of the slide door 14 comes into contact with the vehicle body 12, the closing operation of the slide door 14 by the drive unit 31 is temporarily stopped or decelerated by the elastic force.

  When the latch 62 is released, the drive unit 71 engages with the main body 62a of the latch 62 and is operatively connected to the latch 62. In other words, when the slide door 14 is closed to the half door position, the other end of the closing cable 52 is connected to the roller assembly 22, that is, the center arm 16 via the latch 62 and the drive unit 71. When the latch 62 is released, the latch 62 is unlocked by the latch block 65, and the latch 62 is movable along the side surface of the latch block 65 in the axial direction of the center rail 18. At this time, a pair of guide walls 65c are provided at both upper and lower end portions of the side surface of the locking block 65, and the latch 62 in the released state is guided by these guide walls 65c and runs along the side surface of the locking block 65. Can be moved. Further, since the spring force of the spring 56 acts on the latch 62 in the released state, the latch 62 pulls the drive unit 71, that is, the latch 62 can pull the drive unit 71.

  FIGS. 10A to 10D are explanatory views showing the operation of the switching mechanism, and FIGS. 11A and 11B are explanatory views showing the operation of the connecting unit.

  Next, based on FIG. 10, FIG. 11, operation | movement of the closer mechanism 51 provided in this opening / closing apparatus 24 is demonstrated.

  When the slide door 14 is in the opened state beyond the half-door position, as shown in FIG. 10A, the latch 62 is locked by the locking block 65 and is in the locked state, as shown in FIG. As described above, the movable pulley 58 provided in the connection unit 53 is held at the initial position attracted toward the retracting portion 54a. The switching latch 62 is pressed against the locking surface 65a of the locking block 65 by the tension of the connecting cable 52 as described above.

  When the closing side of an open / close switch (not shown) is operated in this state, the closing cable 25b is driven by the drive unit 31, and the roller assembly 21 supported by the lower rail 17 is pulled by the closing cable 25b, so that the slide door 14 is automatically operated. Close operation. At this time, since the latch 62 is locked to the locking block 65, even if the tension of the closed cable 25b is applied to the moving pulley 58, the moving pulley 58 does not move and the initial state shown in FIG. Held in position.

  When the slide door 14 automatically closes and the roller assembly 22 supported by the center rail 18 reaches the curved portion 18b, the drive unit 71 provided on the roller assembly 22 causes the latch 62 to move as shown in FIG. The connecting leg portion 62b is pushed toward the closing side (the guide pulley 63 side), and the latch 62 rotates counterclockwise in the drawing with the corner portion 65d of the locking block 65 as a fulcrum. When the slide door 14 is closed to the half door position, as shown in FIG. 10C, the latch 62 is rotated to the released state, and the roller assembly 22 is operatively connected to the latch 62. . That is, the latch 62 is driven by the drive unit 71 to be released from the locked state. Thereafter, when the door seal member 14a of the slide door 14 comes into contact with the vehicle body 12, the closing operation of the slide door 14 by the drive unit 31 is temporarily stopped or decelerated by the elastic force.

  When the latch 62 is released, the holder 55 or the movable pulley 58 connected to the latch 62 via the closing cable 52 can be moved inside the case 54, while the holder 55 has a spring force and drive of the spring 56. The tension of the closing cable 25b driven by the unit 31 is applied, and the holder 55 moves away from the retracting portion 54a, that is, in the pulling direction of the closing cable 52, as shown in FIG. Further, the drive unit 71 can be pulled by the latch 62.

  Here, since the intermediate portion of the closed side cable 25b is stretched over the moving pulley 58 so that the moving direction is reversed by 180 degrees, the tension applied to the closing cable 52 by the moving pulley 58 is the traction force of the closed side cable 25b. Doubled. Further, when the door seal member 14a of the slide door 14 comes into contact with the vehicle body 12 and the closing operation of the slide door 14 by the drive unit 31 is temporarily stopped or decelerated due to the elastic force, the lower arm 15 of the closed cable 25b. The traction force of the closed cable 25b by the drive unit 31 is a force that pulls the movable pulley 58 at an intermediate portion thereof from the force that pulls the lower arm 15.

  Here, when the movable pulley 58 moves from the initial position in the direction of pulling the closing cable 52, the length of the closed cable 25b drawn from the outer tube 33b spanned over the movable pulley 58 is shortened. When the closed cable 25b is wound up by the drum 35 of the drive unit 31 until 14 is in the fully closed position, the open cable 25a is slackened. This slack is absorbed by the tensioner mechanism 36a.

  When the movable pulley 58 moves in the pulling direction of the closing cable 52 by the pulling force of the closing cable 25b, the latch 62 is pulled by the closing cable 52 as shown in FIGS. 10 (d) and 11 (b). It moves toward the end of the rail 18 on the closed side. As a result, the roller assembly 22 (drive unit 71) connected to the latch 62 is pulled toward the closed end of the center rail by the closing cable 52. That is, the slide door 14 closed to the half-door position is pulled by the closing cable 52 and pulled from the half-door position to the fully-closed position against the elastic force of the door seal material 14a. When closed, the fully closed state of the sliding door is maintained by a door lock device (not shown).

  On the other hand, when the open side of an open / close switch (not shown) is operated while the slide door 14 is in the fully closed position, the door lock device is released (released) and the open cable 25a is driven by the drive unit 31. The roller assembly 21 supported by the lower rail 17 is pulled by the open cable 25a, and the slide door 14 automatically opens.

  When the sliding door 14 automatically opens, the door lock device is first released, and the sliding door 14 is slightly actuated in the opening direction by the elastic force of the door seal material 14a to move the latch 62 to the initial position side. Acts. The roller assembly 22 supported by the center rail 18 moves to the open side along the center rail 18, and the latch 62 is connected to the drive unit 71, that is, the roller assembly 22 by the drive unit 71 coming into contact with the main body 62a. Then, the roller assembly 22 moves to the open side so as to pull the latch 62. At this time, the connecting portion between the latch 62 and the connecting cable 52 (the locking portion of the cable end 52a) is on the open side with respect to the connecting portion between the driving portion 71 and the latch 62, and the latch 62 and the connecting cable 52 are connected. Since the direction of the tension of the connecting cable 52 is inclined toward the vehicle interior side with respect to the line connecting the connecting portion to the driving portion 71, the driving portion in FIG. A clockwise rotational force about 71 is applied. As the latch 62 moves, the movable pulley 58 is pulled by the closing cable 52 and moves toward the initial position against the spring force of the spring 56.

  When the sliding door 14 is opened to the half-door position, the latch 62 uses the corner portion of the locking block 65 as a fulcrum as shown in FIG. It rotates in the clockwise direction in FIG. When the sliding door 14 is further moved in the opening direction and the connection between the drive unit 71 and the latch 62 is released, the main body 62a of the latch 62 is moved by the tension of the closing cable 52 (the spring force of the spring 56). As shown in FIG. 11A, the movable pulley 58 reaches the initial position and its movement is restricted as shown in FIG. 11A.

  Thus, in the opening / closing device 24, when the slide door 14 is closed to the half door position, the roller of the center arm 16 is closed by the closing cable 52 operatively connected to the closing cable 25b via the connecting unit 53. The slide door 14 can be pulled to the fully closed position by pulling the assembly 22 against the elastic force of the door seal material 14a. That is, the sliding door 14 can be pulled to the fully closed position using the tension of the closed cable 25b. Therefore, it is not necessary to provide a drive source, a drive mechanism, or the like in the closer mechanism 51. Accordingly, the opening / closing device 24 provided with the closer mechanism 51 can be reduced in size, and its mountability on the vehicle body 12 can be improved. Moreover, since it is not necessary to provide an electric motor, a drive mechanism, etc. in the closer mechanism 51, this opening / closing device 24 can be reduced in weight and the cost can be reduced.

  Further, in the opening / closing device 24, a holder 55 is fixed to the closing cable 52, and an intermediate portion of the closing cable 25b is hung on a movable pulley 58 rotatably supported by the holder 55 to close the closing cable 25b. Since the cable 52 is connected to the cable 52, the tension of the closed cable 25b can be increased by the action of the movable pulley 58 and transmitted to the cable 52 for closing. Therefore, the tension, that is, the driving force of the closing cable 52 can be increased without using the large electric motor 41, and the sliding door 14 can be reliably pulled to the fully closed position by the closing cable 52. In addition, since the tension of the closing cable 25b can be increased by the action of the movable pulley 58 and transmitted to the closing cable 52, the electric motor 41 can be downsized to make the opening / closing device 24 smaller and lighter, The cost can be reduced.

  Further, in the opening / closing device 24, the looseness of the open side cable 25a caused by the movement of the movable pulley 58 is absorbed by the tensioner mechanism 36a. Therefore, the closing cable 52 is removed using the tension of the close side cable 25b. Even if the structure is driven, the opening / closing device 24 can be reliably operated without causing the open side cable 25a to slack.

  Further, in this opening / closing device 24, the switching mechanism 61 is configured by a latch 62, a locking block 65, and a drive unit 71, and when the slide door 14 is closed to the half door position, the latch 62 is driven by the drive unit 71. When driven, the latch 62 and the drive unit 71, that is, the center arm 16 and the closing cable 52 are operatively connected. Therefore, the switching mechanism 61 for switching the sliding door 14 from the normal closing operation to the retracting operation. The cost of the opening / closing device 24 can be reduced.
