  As shown in FIG. 7, the slide door 4 has a front lock 31 and a rear lock 32 (fully closed lock) for holding the slide door 4 in the fully closed position, and a slide door 4 in the fully open position. The fully open lock 33 is provided. Moreover, these locking devices (31-33) are connected to the inside door handle 35 and the outside door handle 36 via transmission members 34, such as a wire cable and a link. In the present embodiment, an operation transmission system 37 for opening and closing the slide door 4 is thereby formed.

  Specifically, an operation input to each door handle (35, 36) is input to a remote control (remote control device) 38 provided in the middle of the operation transmission system 37. Based on the operation of the remote control 38, an appropriate locking device (31 to 33) corresponding to the operation input is unlocked.

  As shown in FIG. 4, in the present embodiment, the locking device 40 that constitutes the fully open lock 33 is provided on the connecting member 7 </ b> B that is connected to the lower rail 5 </ b> B. Specifically, the locking device 40 is provided on the back side of the support arm 21 (the back side in the drawing in the figure). A wire cable 41 is used for the transmission member 34 that connects between the lock device 40 and the remote control 38. In the present embodiment, as described above, the wire cable 41 is routed inside the bead 30 having a curved shape that is convex on the front side of the support arm 21 (the front side in the figure). It has become.

  More specifically, as shown in FIG. 8, the locking device 40 of the present embodiment includes a latch 42 that is rotatably provided with an engagement groove 43 that is open on a peripheral surface 42 s of the locking device 40. And a pole 44 capable of restricting the rotation. On the vehicle body 2 side, a striker 45 that can be engaged with the engagement groove 43 of the latch 42 when the slide door 4 is moved to the fully open position is provided. The lock device 40 restricts the forward movement of the slide door 4 by holding the striker 45 in the engagement groove 43, thereby holding the fully open position. It is possible.

  More specifically, the lock device 40 includes a bracket 48 that has two support shafts 46 and 47 that are parallel to each other and is fixed to the back side of the support arm 21 (see FIG. 6, the back surface S2 side). The latch 42 and the pole 44 are pivotally supported by these support shafts 46 and 47, respectively.

  The latch 42 and the pole 44 are urged in directions opposite to each other based on the elastic force of the torsion coil springs 50 and 51 fitted to the support shafts 46 and 47, respectively. Specifically, the latch 42 is urged clockwise in FIG. 8, and the pole 44 is urged counterclockwise. Thus, the latch 42 and the pole 44 are in a state in which the peripheral surfaces 42 s and 44 s are in sliding contact with each other.

  Further, an engagement protrusion 52 is formed on the peripheral surface 44 s of the pole 44. In addition, an engagement recess 53 that can engage with the engagement protrusion 52 is formed on the peripheral surface 42 s of the latch 42. The locking device 40 according to the present embodiment can hold the rotation position of the latch 42 based on the engagement relationship between the engagement protrusion 52 of the pole 44 and the engagement recess 53 of the latch 42. It has become.

  Specifically, when the locking device 40 is in the unlocked state, the pawl 44 has a circumferential surface 44 s located at the proximal end portion of the engaging projection 52, and the engaging recess 53 on the circumferential surface 42 s of the latch 42. In addition, it comes into sliding contact with a portion closer to the opening portion of the engagement groove 43 (a position indicated by a two-dot chain line in FIG. 8). At this time, the rotation position of the latch 42 is set so that the engagement groove 43 opens to the vehicle rear side. That is, the locking device 40 provided on the support arm 21 of the connecting member 7B is configured to come in contact with and separate from the striker 45 provided on the vehicle body 2 side by moving back and forth integrally with the slide door 4. Yes. In this embodiment, the engagement groove 43 of the latch 42 and the striker 45 are engaged with each other based on the opening operation of the slide door 4.

  Thereafter, when the slide door 4 further moves toward the rear of the vehicle, the latch 42 is pressed against the striker 45 engaged with the engagement groove 43, and rotates counterclockwise in FIG. Move. When the slide door 4 is in the fully open position, the engagement protrusion 52 of the pawl 44 is configured to engage with the engagement recess 53 of the latch 42.

  That is, in this embodiment, based on the engagement relationship between the engagement protrusion 52 and the engagement recess 53, the rotation of the latch 42 in the clockwise direction in FIG. The rotation of the latch 42 in the direction in which the engagement with the striker 45 is released is restricted. As a result, the rotation position of the latch 42 can be held in a state in which the striker 45 cannot be detached from the engagement groove 43 of the latch 42 (locked state).

  In the present embodiment, the engagement protrusion 52 of the pole 44 is formed with a connection portion 55 with the wire cable 41 constituting the transmission member 34. Specifically, the wire cable 41 of this embodiment has a well-known structure in which a metal wire 41a is inserted into a resin tube 41b, and the pole 44 has a tip of the wire 41a. A connection portion 55 having a groove portion capable of locking the ball-shaped end portion 41c provided on the inner surface is formed. The bracket 48 is formed with a cable holding portion 56 that holds one end of the tube 41b.
