As described above, according to the sliding window of the present invention, opening / closing of the shoji screen and engagement / disengagement of the hook with the engaging member can be performed by a series of operations of the operating handle. The operation is simpler than the conventional one in which the opening and closing of the hook and the engagement and disengagement of the hook with the engaging member must be performed separately. Further, when the operation handle is rotated to close the shoji, the hook can be automatically engaged with the engaging member after closing the shoji, so that it is possible to forget to engage the hook with the engaging member. This will prevent the shoji from opening due to wind, and increase the safety in terms of crime prevention. Further, when the operation handle is rotated to open the shoji, the engagement of the hook with the engaging member is automatically released before the shoji is opened. It is possible to prevent damage to the transmission means for converting into, the hook, the engaging member, and the like.
