  In the former conventional example, it is suitable for use in an outset sliding door, but even when the sliding door is not closed, the lock can be protruded. There is a problem in that the mounting frame is damaged by colliding with the mounting frame or the sliding door lock device is broken.

  As a device to solve this problem, a sliding door lock with a trigger bolt as in the latter conventional example has been proposed, but this is because the trigger bolt appears and disappears from the center in the thickness direction of the sliding door. If this is applied to an outset sliding door, it is necessary to make the trigger bolt support protrude from the wall on the side of the mounting frame to the position where the trigger bolt can come into contact. Therefore, there is a problem that it is dangerous and also disturbs walking, and the present invention has an object to solve this problem.

  In order to solve the above-mentioned problems, the present invention provides that the lock body is configured such that the lock piece protrudes from the lock box in a direction perpendicular to the sliding door opening and closing direction, and the protruding lock piece is engaged with and disengaged from the receiver. The sliding door locking device is provided with a trigger member separate from the lock body on the surface side where the lock piece appears and disappears, and the trigger member can move the sliding tool in the sliding door opening / closing direction to the fixture attached to the sliding door The sliding tool is provided with an opening through which the lock piece can be projected and retracted, a protruding part protruding from the mounting tool in the closing direction of the sliding door, and the opening to be locked. The stopper is provided with a blocking portion that can be prevented from coming into contact with the piece, and the receiving device is provided with a contact portion with which the protruding portion of the trigger member comes into contact when the sliding door is closed, and the protruding lock piece is locked. When the sliding door is opened, the sliding tool is provided. The protruding portion protrudes and the blocking portion is urged in a direction to block at least a part of the protruding direction of the lock piece. Even when the locking device is operated, the lock piece does not protrude by contacting the blocking portion. When the sliding door is closed, the projecting portion of the trigger member comes into contact with and is pushed into the abutting portion of the receiving device, the sliding device moves, and the blocking portion that blocks the projecting direction of the locking piece moves. Will be able to protrude through the opening of the sliding tool, and by operating the locking tool, the locking piece will protrude and be locked to the locking part of the receiving tool so that it can be locked Is a sliding door locking device.
