When fixing the cover material to an attachment frame or a newly installed frame with screws, the fixing work is complicated because the fixing work is performed using screws. On the other hand, it is conceivable to adopt a structure in which the cover material is fitted into the attachment frame or the newly installed frame. In this case, there is a structure in which the cover material is formed into an elongated shape and the cover member is fitted and attached so as to be movable in the longitudinal direction.

However, if the cover material is fitted into the attachment frame or the new frame in a longitudinally movable manner, there is a possibility that the cover material will be moved in the longitudinal direction. Therefore, it is required to be able to restrict movement of the cover material in the longitudinal direction.

An object of the present disclosure is to provide a refurbished fitting that can restrict movement of a cover material in the longitudinal direction.

The present disclosure relates to refurbished fittings that are attached to an existing frame provided in an opening of a building, and which includes a new frame configured with four circumferences, and a new frame that is attached to the outer circumference of the new frame with four circumferences. An attachment frame attached to the inner peripheral side of the existing frame, an elongated cover material attached to the attachment frame or the new frame, and a regulation structure that regulates movement of the cover material in the longitudinal direction.
