When locked by a lock plate that is held between them and can be slid by the operation of a key, and a grip groove that is fixed to the shaft and is recessed at one end in the sliding direction of the lock plate, the lock plate cannot rotate. A lock body that is rotatable when the grip groove is separated by sliding of the plate, a prismatic portion that is formed on a part of the shaft and has a polygonal cross section, and a prismatic portion that is disposed so as to surround the prismatic portion. An annular elastic body that has a spring portion elastically contacting the peripheral surface and that positions the handle at each predetermined rotation position is provided, and the lock body can be held by the holding groove at one position where the prismatic portion is positioned by the annular elastic body. Position of the prism and the lock The lock plate is formed with a long hole through which the screw is inserted to guide the slide of the lock plate, and the lock plate is operated by a key to slide the lock plate and lock it in the grip groove of the lock plate. By locking the lock body by fitting the bodies to each other, it is possible to lock the handle by disabling the rotation operation of the handle. Moreover, since the lock body is directly attached to the shaft and the lock plate is slidable, it can be compactly stored in the vertical rail of the gate or the handle box which is narrower than the lock plate that is rotatable. It is possible. Further, a rectangular columnar portion having a polygonal cross section is formed on a part of the shaft, and a ring-shaped elastic body for elastically contacting the peripheral surface of the prismatic portion is provided for positioning the handle at predetermined rotation positions. Since the handle is arranged so as to surround the handle, it is possible to maintain the position of the handle so that the handle does not rotate even if a moment acts around the handle axis due to the weight of the handle. That is, by setting the positional relationship between the prismatic portion and the lock body so that the lock body can be held by the grip groove at one position where the prismatic portion is positioned by the annular elastic body, There is an advantage that the direction of the lock body can be held by the body and the lock body can be easily held by the holding groove of the lock plate. In addition, since the screw for fixing the pressing plate is inserted into the long hole of the lock plate to guide the sliding of the lock plate by the screw and the long hole, the screw fixes the pressing plate and guides the lock plate. Therefore, there is an advantage that the number of parts can be reduced as compared with the case where a lock plate guide is separately provided. Moreover, since the lock body is positioned by the annular elastic body and the prism, and the lock plate is guided by the screw and the long hole, the lock body can be smoothly gripped by the grip groove provided in the lock plate. Is played. Further, a rectangular columnar portion having a polygonal cross section is formed on a part of the shaft, and a ring-shaped elastic body for elastically contacting the peripheral surface of the prismatic portion is provided for positioning the handle at predetermined rotation positions. Since it is arranged so as to surround it, it is possible to maintain the position of the handle so that the handle will not rotate even if a moment acts around the axis of the handle due to the weight of the handle. If the lock plate is slid in a state of being positioned at a predetermined angle, the grip groove can be smoothly attached to and detached from the lock body. In short, since the lock plate slides to fit the grip groove into the lock body, it is necessary to position the rotation position of the lock body at a predetermined position with respect to the grip groove, and the annular elastic body and the prismatic portion are used. This makes this positioning easier.
