2. Description of the Related Art Conventionally, a sickle has been used to lock a sliding door. For example, a sickle lock with a rotatable sickle lock on the board is attached to the sliding door surface, the vertical frame is dug at the location corresponding to the sickle lock, and a sickle lock is attached to the dug surface. The sliding door is locked by rotating the sickle lock body so that the tip of the sickle lock body fits into the sickle lock receiver.

Further, as a separate sickle lock, a front and back hole is formed on the front and back surfaces of the sliding door, and a front opening hole is formed from the opening of the sliding door to the front and back holes. A sickle lock body which is connected to the cylinder inside and is operated is inserted into the mouth opening hole, and the sickle lock body enters and exits from the sliding door opening by the operation of the operation unit, and the sliding door of the vertical frame is inserted. The sickle lock receiver is attached to the place where the abutment part is located against the sickle lock body, and the sickle lock receiver is attached to the dug out surface. Some are locked with sliding doors.

[0004]

In the former case, when the sickle lock receiver is attached to the vertical frame, a digging into which the tip of the sickle lock body is fitted must be provided in the vertical frame. It takes time and effort to position the place, that is, the place where the digging is to be performed, and to perform the work of providing the digging.

[0005] In the latter case, in addition to the problems mentioned in the former, since it is necessary to drill front and back holes and a kiguchi hole in the sliding door from two directions, from the front and back, and from the kiguchi, it takes time to drill holes in the sliding door. Take it. In addition, since the mechanism of the sickle lock becomes complicated and the price of the sickle lock increases, the installation must be performed in two directions, which increases the manufacturing cost and the price of the sliding door with the final locking mechanism. There are problems such as.
