(2) Each component such as a slider, a hook, and a stopper can be mounted on the lock case in advance, and then the lock case can be incorporated into the inner frame. Therefore, the efficiency of the assembly work can be improved. (3) The lock case, the slider, and the operating member are compact so that they can be easily combined. Therefore, the sickle lock can be mounted on the inner frame in a short time. (4) Since the basic members are assembled into the inner frame via the lock case, the appearance is not noticeable, and a security effect can be expected. (5) Since the kama is completely incorporated into the inner frame via the lock case, the shape of the kama itself can be made relatively compact. (6) Since the kama is pivotally supported via a plurality of movable shafts, it smoothly rotates, and the first movable shaft is laid across the horizontally long hole of the lock case, and the slider is inclined in the oblique direction. When the slider is lowered, the stirrer can be moved to the indoor side and the outer frame can be drawn to the inner frame. (7) Since the stopper for the hook is provided, the slider is prevented from freely moving by the stopper.
Therefore, the stile does not easily rotate in the release direction.
