When moving, the displacement of the first pin 54 is blocked by the specified elastic force as described below, and the rotation of the gear 38 engaged with the first pin 54 is prevented, thereby preventing the rotation of the gear 32 to prevent the door from closing. The elastic displacement blocks the member 60. Specifically, the engagement displacement member 56' has a first insertion pin 54' at one end and a second insertion pin (support engagement portion) 62 that can displace and engage the engagement displacement member 56 to the support body 52. The support body 52 has a V-shaped groove (support portion) 64 that is slidably engaged with the engagement displacement member 56. The groove 64 is formed in a heart shape as seen from the table 4 to the sixth drawing, and the first pin 54 is reversed when the gear -11 - 1351463 38 is rotated forward (that is, rotated clockwise with the door opening action). When the direction limit position (Fig. 4) is moved in the forward direction limit position (Fig. 6), the second plug 62 can be displaced along the groove 64 as shown on the right side without any resistance. Further, when the first latch 54 moves from the forward direction limit position (Fig. 6) to the reverse direction limit position (Fig. 4), the second latch 62 can be seen as the left side along the groove 64. The displacement of the first pin 54 reaches the left side of the groove 64 before reaching the reverse direction limit position (Fig. 4) from the forward direction limit position (Fig. 6) to the central portion of the circular path. The upper end prevents relative displacement relative to the support 52. When the first latch 54 that is engaged at the upper end of the left portion of the groove 64 is displaced toward the central portion of the circular path, the first latch 54 causes the support 52 to pivot in the counterclockwise direction at the pivot 50. around. As described above, the groove 64 has a state in which the first pin 54 is engaged with the second pin 62 when the first pin 54 is in the forward rotation limit position (Fig. 6) and the reverse direction limit position (Fig. 4). Supporting central portion 64-1: when the first latch 54 is displaced from the reverse direction limit position (Fig. 4) along the circular arc path to the forward direction limit position (Fig. 6), in order to guide the displacement a second latch 62 that forms a displacement, and a guide surface 64-2 for opening the door extending from the support central portion 64-1; and a circular path along the limit position (Fig. 6) of the first latch 54 from the forward rotation direction When the displacement is in the reverse direction limit position (Fig. 4), the first pin 54 located at the support center portion 64-1 is guided to be displaced from the support center portion 64-1, and the first pin 54 reaches the arc. In the middle of the path, the door closing guide surface 64-3 extending from the support center portion 64-1 with a length capable of preventing the relative displacement of the second pin 62 phase-12-1351463 from the support body 52 is blocked. The support body 52, as seen in Fig. 2, is composed of two members on the front side and the deep side, and is pivotally connected to the casing 30 of the door closing drive device, and is provided to extend parallel to the pivot 50 and has a rectangular cross section. The insertion hole 66 is inserted through the cross-sectional rectangular pressing member 68 which is pressed by the elastic displacement preventing member 60. Specifically, the pressing member 68 is formed in a cylindrical shape, and the screw is engaged with the screw member 70 rotatably provided to the casing 3〇 parallel to the pivot 50 of the support body 52, and the rotation of the screw member 70 can push Member 68 is displaced in the axial direction. The elastic displacement preventing member 60 is provided at the bottom of the insertion hole 66 at intervals in the axial direction of the insertion hole. Further, the pressing member 68 is provided with a pressing portion 68·1 having an inclined surface corresponding to the two elastic displacement preventing members 60. Therefore, the rotation of the screw member 70 about its axis allows the pressing member 68 that is engaged with the screw member 70 to be displaced in the axial direction, and the elastic displacement preventing member 60 can be adjusted to cope with the pressing portion 68-1. Relative position. When the sliding door is to be displaced in the closing direction, and the gear 38 is to be rotated in the counterclockwise direction, the second latch 62 as described above is guided along the guiding surface 64-3 of the V-shaped groove 64 to the upper end thereof. Then, the movement along the guiding surface is stopped, so that when the supporting body 52 is pivoted around the pivot 50 (in the counterclockwise direction in the drawing), the pressing member 68 is opposed to the insertion hole 66. The force is displaced downward, and then the push is engaged with the elastic deformation preventing member 60. As a result, the pivoting of the support body 52 is prevented. Therefore, the displacement of the first pin 54 is prevented, and the rotation of the gear 38 is blocked, and the door closing operation is stopped. The elastic displacement preventing member 60, when a certain amount of force is applied to the stopped sliding door in the closing direction as described above, is more elastically deformed to further rotate the supporting body 52 counterclockwise, thereby allowing the first latch. The travel of the arcuate path is shifted to the reverse direction limit position (Fig. 4 position), so that the sliding door can be formed to be automatically closed by the door closing driving device 22. Fig. 10 and Fig. 11 are diagrams showing essential parts of the second embodiment of the door closing preventing device according to the present invention. In this embodiment, the elastic displacement preventing member 60 is integrally formed to extend between the two members for the support body 52, and the pressing member 68 forms a relative displacement to the support body 52, and can be disposed at The protrusion (pressing portion) 68-1 of the pressing member is formed to be pressed and engaged with the elastic displacement preventing member 60. 12 and 13 are views showing the position of the pressing member in the axial direction by the rotation of the screw member similar to the screw member 70 of the first embodiment, and the pressing member 68 is pushed. An example of adjusting the elastic force of the elastic displacement preventing member 60 when the pressure is engaged with the elastic displacement preventing member 60.
