Claims

[Scope of utility model registration request]

A door body that is opened and closed in a sliding door manner along a groove-shaped guide is provided with a rotating shaft that serves as a center of rotation when the door body is opened and closed in a hinged door manner, and
This rotating shaft is provided with a deformed part having different width dimensions at points perpendicular to each other, and a pair of movable pieces connected to the groove-shaped guide so as to be movable in opening and closing and always biased in the direction of closing movement are accommodated in the groove-shaped guide. The irregularly shaped portion is interposed between the movable pieces, and the pair of movable pieces are pushed apart by the irregularly shaped portion as the door body is opened in a swinging manner around the rotation axis,
A door opening/closing device characterized in that the free ends of the pair of movable pieces hold a shoe that comes into contact with the inner surface of the groove-shaped guide when the movable pieces are pushed apart.
