Claims

[Scope of utility model registration request]

After the arm 5 pivotally supported on the support part 1 so as to be horizontally rotatable, the door 3 is moved through a slider 8 pivotally supported on the tip of the arm 5 and a sliding rail 12 installed on the slider 8 so as to be movable back and forth. In the opening/closing locking/disengaging mechanism for a sliding door that allows for free movement back and forth, a turning restriction mechanism for restricting turning of the arm 5 is provided on one side of the support section 1, so that the arm 5 can be turned freely relative to the slider 8. The supported arm tip shaft 9 is fixed to the slider 8, and the arm tip shaft 9 rotatably supports a lock plate 11 and has an inner diameter r.
A winding spring 13 which is slightly smaller than the outer diameter R of the arm tip shaft 9 and has elasticity in the winding direction is fitted, and a lock pin 14 provided on the sliding rail 12 is engaged with one side of the lock plate 11 when the door is opened and closed. An opening/closing locking/unlocking mechanism for a sliding door, characterized in that a recess 11a for release is formed, and one end 13a of a winding spring 13 is locked to an arm 5 and the other end 13b is locked to a lock plate 11.
