である。[Function] With such a configuration, when the friction surface of the pusher is elastically in close contact with the fixed surface, the self-propulsion of the sliding door is stopped. When force is applied to the sliding door from such a locked state to move it in either the left or right direction, the pusher is temporarily elastically deformed due to the friction between the friction surface and the fixed surface, and then moves in the opposite direction to the sliding door movement direction. Turn in the direction. The forced retraction means uses the rotation of the support shaft of the pusher operating means as the pusher rotates to elastically bias the support shaft, so when the friction surface separates from the fixed surface, the pusher moves away. It is rotated to a standby position and held there. As a result, the locked state of the sliding door is released, and the friction surface of the pusher is prevented from contacting the fixed surface while the sliding door is moving. After the sliding door is moved to a desired intermediate position, when an operating force is applied to the manual operation part to forcibly turn the pusher from the standby position to the locking position against the elastic biasing force of the forced retraction means, the above-mentioned As shown in the figure, the friction surface of the pusher comes into elastic contact with the fixed surface, and the self-propulsion of the sliding door is stopped. That is, since this friction surface has a certain width, the pusher cannot be rotated to the standby position unless a force of a certain level or more is applied to the sliding door to elastically deform the pusher. Therefore, the self-propelling of the sliding door can be stopped by this pusher.

引戸２の移動に障害となるような不具合が回避される。From this locked state, as shown in FIG.
When a force is applied to the sliding door 2 to move it in either the left or right direction, the pusher 4 is supported in the opposite direction to the moving direction R of the sliding door 2 due to the friction between the friction surface 42a of the friction member 42 and the one side 1b of the wall 1. It rotates around the axis 51. During this turning, the friction member 42 is temporarily elastically deformed. When the support shaft 51 rotates in the same direction as the presser 4 as the presser 4 rotates, the rotation causes the tip 62 of the elastic member 62 to rotate.
A biasing force acts on the locking surface 61 of the support shaft 51 from b in the direction of rotating the support shaft 51, and the support shaft 51 and the presser 4
assists in turning movements. Then, the friction surface 42 of the presser 4
When a separates from one side 1b of the wall 1, the presser 4 is rotated to the standby position A and stably held at the standby position A. As a result, the locked state of the sliding door 2 is released, and the friction surface 42a of the pusher 4 touches the wall 1 while the sliding door 2 is moving.
Since the pusher 4 does not come into contact with one side 1b of the sliding door 2, a problem in which the pusher 4 becomes an obstacle to the movement of the sliding door 2 is avoided.

れることになる。After moving the sliding door 2 to a desired intermediate position, as shown in FIG. When it is horizontally rotated from the standby position A in the direction of the locking position B, the friction member 42 first comes into contact with the wall 1. From this state, when the manual operation unit 52 is further operated to forcibly rotate the pusher 4 and the friction surface 42a is brought into close contact with the side surface 1b of the wall 1 as described above, the self-propulsion of the sliding door 2 is stopped. Ru. That is, since the friction surface 42a has a constant width in the left-right direction, when it elastically comes into close contact with one side surface 1b of the wall 1, this state is maintained unless an external force is applied, and the sliding door 2 is in the locked position. It will be held at B.

can be left open at a desired intermediate position. Also, if you want to release the locked state of sliding door 2,
Just by slightly moving the sliding door 2 to either the left or right, the locked state can be reliably released. Therefore, even if a person who does not know the situation opens or closes the half-open sliding door 2, there will be no problem such as excessive external force being applied to the intermediate stop device 3.

By forming 42a, the presser 4 can be made stronger and its durability can be effectively improved. Furthermore, by using a material with high sliding friction for the friction member 42, the friction force between the friction surface 42a and the side surface 1b of the wall 1 can be effectively increased, so that the sliding door can be reliably stopped at a desired intermediate position. You can leave it there.

The presser 4 can be quickly turned to the standby position A. At the standby position A, the tip 62b of the elastic member 62
Since the locking surface 61 and the locking surface 61 come into close contact with each other and prevent rotation of the support shaft 51, the presser 4 can be reliably and stably held at the standby position A.

うなことはない。Further, the forcible retraction means is configured such that the tip end portion elastically contacts four flat locking surfaces provided on the outer surface of the support shaft and two opposing surfaces of the locking surfaces to elastically bias the presser toward the standby position. If the sliding door is equipped with a plate-like or linear elastic member, the pusher can be quickly rotated to the standby position and stably held at the standby position when moving the sliding door. Therefore, the pusher does not become an obstacle when moving the sliding door.
