Description of the Related Art An opening device of this type includes a frame body provided at an opening of a building, the frame body comprising an upper frame, a lower frame, and right and left vertical frames. There is known a sash provided with a sliding door provided in the sash. In this sash, an airtight material is provided between the frame and the shoji and between the shoji, so that when the shoji is fully closed, the airtightness between the room and the outside can be maintained. For this reason, especially when high-rise floors such as buildings and condominiums are susceptible to wind pressure, or when a pressure difference occurs between the inside and outside of the room due to the use of a ventilation fan, the sliding door when fully closed is pressed against the frame and the frictional resistance increases, There was a problem that the opening and closing of the shoji was heavy, making it difficult to open the shoji. In order to solve such a problem, a large handle or an assist handle (opening / closing assist handle) has been proposed for a door frame of a shoji, but such a handle is desired to be retrofitted to an existing sash. There is a request. However, in a conventional sash (opening device), it is necessary to insert a back plate member into a door frame in order to attach a handle. It is necessary to remove the sash from the body, remove the tapping screw for assembling the sash, and remove the anti-sway component of the sash, which is very troublesome. In addition, there is a method of using a turn nut or the like instead of the back plate member, but there is a problem that the door frame is deformed due to metal fatigue while repeatedly opening and closing the shoji. [0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an opening device which can be easily attached to a door frame of a shoji by retrofitting, thereby improving workability.
