Description

TECHNICAL FIELD The present invention relates to a fitting having a sliding door shoji.

BACKGROUND ART Conventionally, as fittings having a sliding door shoji, for example, sashes (fittings) provided with a frame and an outer and inner shoji which are housed in the frame in a sliding manner so as to be openable and closable are known. A vertical frame (vertical frame) of such fittings is formed with protruding fins, and the door frame has a drawing member (door drawing piece) held in a groove formed on the side of the door. ing. When the outer shoji or inner shoji is closed, the drawing member abuts against the fins of the vertical frame, so that the door tip portion of the outer shoji or inner shoji is drawn in the prospective direction.
Since the outer shoji and the inner shoji have a face material such as glass and are heavy, when the drawing member comes into contact with the fins of the vertical frame, a large force acts on the door frame and the vertical frame. In particular, the door frame, which is not fixed to the frame like the vertical frame, has a surface material such as glass and a part where the pulling member contacts the fin of the vertical frame, and is arranged in the moving direction of the outer and inner shoji. The fins are arranged in such a manner that a moment is less likely to act on them, and a hollow portion is provided between the face member and the abutting portion between the drawing member and the fins to increase the rigidity.
