When the pole 18 is rotated from the engagement position with the intermediate striker 16b to the non-engagement position, the lock portion 18b and the hook portion 17c are engaged to hold the pole 18 in the non-engagement position.

  The base plate 15 is provided with a full-open stopper mechanism 19 that engages with a full-open striker 16d fixed to the body 16 to lock the slide door 11 in the full-open position. The full-open stopper mechanism 19 and the slide door 11 are provided. Since the lock mechanism for locking in the fully closed position is not related to the gist of the present invention, the description thereof is omitted.

  The operation of the above configuration will be described. When the sliding door 11 is closed and the window glass 13 is fully closed, when the window glass 13 is opened via the forward / reverse winding drive unit 25, as shown in FIG. The first link 33 is pressed against the first surface F of the projecting portion 39 of the two links 37, and the first link 33 rotates about the pin 31 counterclockwise in the figure. Then, the inner wire 51b of the drive wire 51 is pulled, and the hook member 17 of the intermediate stopper mechanism rotates counterclockwise in FIG. 5, and the hook portion 17c and the lock portion 18b are disengaged.

  In this embodiment, while the inner wire 51b of the drive wire 51 is being pulled, the first link 33 and the drive are provided so that the angle formed by the first link 33 and the inner wire 51b of the drive wire 51 is 90 °. Wire 51 is arranged.

  When the slider member 28 moves downward, the second surface S of the second link 37 is pressed. The second surface S is a tapered surface in which the distance between the second surface S and the line segment L gradually increases as going downward. Therefore, the inner surface 51b of the drive wire 51 is pulled by the second surface S through the first link 33 with an attractive force greater than the attractive force of the drive wire 51 on the first surface F.

  Therefore, the counterclockwise rotation position of the hook member 17 is that the slider member 28 is moved from the intermediate position of the window glass 13 to the fully open position as well as when the slider member 28 first rotates the first link 33. Holds securely until moving.

  The pole 18 is urged to rotate in the clockwise direction in FIG. 5 by the spring means. When the slide door 11 is fully closed, the pole push-back member 16c prevents the rotation. In this state, when the slide door 11 is opened, the engagement between the pole push-back member 16c and the pole 18 is eventually released, and the pole 18 is rotated to the engagement position with the intermediate striker 16b. Therefore, when the slide door 11 is further opened, the pole 18 comes into contact with the intermediate striker 16b and the intermediate stopper mechanism works. Thus, according to the present embodiment, the intermediate stopper mechanism can be reliably operated by opening the slide door 11 in a state in which the window glass 13 is opened larger than the predetermined intermediate position.

  As described above, the hook member 17 is urged to rotate in the direction in which the inner wire 51b of the drive wire 51 is pulled, and the first link 33 is urged to rotate in the clockwise direction in FIG. Will be. Therefore, the urging means for urging the first link 33 in the same direction can be omitted, but the first link 33 is urged in the direction not pulling the drive wire as a single unit on the guide rail 21 side. It is preferable to keep it.

According to such a configuration, the following effects can be obtained.
The second link 37 is formed so as to be connected to the first surface F, and the slider member 28 is pressed until the window glass 13 reaches the fully open position, and is driven with a force larger than the pulling force of the driving wire 51 on the first surface F. By forming the second surface for pulling the inner wire 51b of the wire 51, the drive wire 51 continues to be pulled, and the intermediate stopper mechanism does not malfunction.

Therefore, it is not necessary to increase component accuracy and reduce mounting errors, and it is possible to keep component costs and assembly costs low.
The present invention is not limited to the above embodiment. In the above embodiment, a parallel motion mechanism is provided so that the line L and the movement locus of the slider member 28 are parallel, and until the window glass 13 reaches the fully open position, the second surface S of the second link 37 is When the slider member 28 moves downward so that the slider member 28 continues to be pressed in the direction in which the drive wire 51 is pulled, the second surface S of the first link 33 is pressed. The second surface S is a tapered surface in which the distance between the second surface S and the line segment L gradually increases as going downward.

  In addition, as shown in FIG. 6, a pin 35 ′ that is an attachment portion of the second link 37 ′ to the first link 33 ′ and a long hole 41 ′ that is a second link guide means of the second link 37 ′. Even if the straight line L passing through the guided pin 43 ′ and the movement trajectory T of the slider member 28 intersect, the same effect as the embodiment shown in FIG. 1 can be obtained.

  Further, the second surface S is set so that the distance between the second surface S and the line segment L is constant, and the first link 33, so that the line segment L and the movement locus T of the slider member 28 intersect each other. The bracket 29 provided with the second link 37 and the long hole 41 as the second link guide means may be attached to the guide rail 21.

  Furthermore, the arc-shaped elongated hole 41 is used as the second link guiding means, but one end is rotatably attached to the bracket 29 and the other end is rotatably attached to the lower end of the second link 37. The link which comprises a parallel crank mechanism in cooperation with the 1st link 33, the 2nd link 37, and the bracket 29 may be sufficient.

  Alternatively, the protrusion 39 of the second link 37 may be eliminated, the upper end of the second link 37 and the end of the first link 33 may be rotatably attached, and the first surface F may be provided on the first link 33.
