OPENING/CLOSING DEVICE

摘要

The inner surface of one side section of a frame (1) has the base-end section of a rotation arm (44) of a rotation-biasing means (4) provided so as to be rotatable. A roller (47) is provided on the tip-end section of the rotation arm (44). The roller (47) is pressed against and contacts the rear surface (2a) of a door (2) as a result of the biasing by the rotation-biasing means (not illustrated). The rear surface of the door (2) is equipped with a damper means (5). The damper means (5) has a contact member (52) for pressing against and contacting the roller (47) when the door is in the closed position or in a prescribed intermediate position. The contact member (52) minimizes the speed at which the roller (47) moves forward.
