• the engaging portion 2 c is detached from the engaged surface portion 7 while the rotating base portion 2 a rotates clockwise.
• the locking portion 15 b of the guide traveling body B is engaged with the contact piece 2 b 2 of the hook member 2 through the process shown in FIG. 10 C and FIG. 11 A. It fits in a substantially U-shaped recess between the stop piece 2 b and the abutted piece 2 b 2 .
• the force obtained by subtracting the resistance force T of the buffer member 4 from the elastic force F of the elastic member 3, that is, the force F ⁇ T becomes a substantial door closing force P.
• the sliding door 18 is decelerated from the initial door closing speed V n by the person's door closing operation, and by the door closing force P, the sliding door 18 becomes a gentle speed V m, The operation is performed, and it is forcibly moved to the door closing side and reaches the end of the door closing direction to complete the door separation operation (see Fig. 11 B).
• the hook member 2 is located close to the door closing side (to the right side in FIG. 12 A) in the initial state, and the guide member attached to the guide traveling body B 15 is in a locked state with the locked piece 2 b of the saw member 2.
• the guide member 15 attached to the guide traveling body B is engaged. Pulling the locked piece 2 1 ⁇ of the hook member 2 in the stopped state, the hook, the saw member 2 and the sliding member 1 are forcibly moved along the main guide portion 6 to the door opening side.
• the sliding restriction projection 1 g comes into contact with the door opening side end of the sliding restriction portion, It serves as a stagger in the sliding motion of the sliding member 1 and the sliding of the sliding member 1 is stopped.
• the engaging portion 1c of the hook member 2 has reached the seven engaged surface portions.
• the hook member 2 b of the hook member 2 is pulled out by the locking portion 15 b of the guide traveling body B so that the hook member 2 is pulled out. Rotates through the pivot base 2a. Specifically, as shown in FIG. 7B, FIG. 8B and FIG.
• the hook member 2 rotates counterclockwise around the rotation base 2a and the engagement portion 2c is covered.
• the engagement surface portion 7 is moved and engaged.
• the hook member 2 is engaged with the engagement portion 2 c and the engaged surface portion 7 with appropriate pressure by the elastic force of the sliding member 1 and the elastic member 3 connected to the sliding member 1.
• the hook member 2 is temporarily stopped at the seven engaged surface portions.
• the hook member 2 Since the hook member 2 is inclined at the door opening side, the top portion of the locked piece 2 b is lowered, so that the locking portion 15 b of the guide traveling body B is The latching piece 2b is detached from the latching piece 2b, and the latching state of the latching portion 15b and the hook member 2 is released, and the sliding door 18 is further moved to the opening side to complete the opening operation.
