To dispense with the operation of preventing an opened door body from making a full closing motion.
One edge side portion is rotatably mounted at one edge of an opening 2 which is opened in a main body 1, and a base end of a regulation stay 7 is rotatably mounted on the door body 3 for opening/closing the opening 2. A door opening/closing amount regulation groove 11 for movably guiding a leading end of the regulation stay 7 is formed inside the opening 2 of the main body 1. The regulation groove 11 comprises a half-opening regulation groove portion 12 which stops the movement of the regulation stay 7 in a midway position to prevent the fully closed state of the opening 2 of the door body 3, and a full-closing regulation groove portion 13 which branches off from an intermediate position of the groove portion 12 so as to enable the movement of the regulation stay 7 up to the fully closed state of the door body 3. A rotational direction as the closing direction of the door body 3, and the direction of the action of the gravity of the door body 3 or the action of an urging force on the door body 3 are set as the same direction. The groove portion 13 of the regulation groove 11 branches off from the groove portion 12 in a direction different from the direction of the action of the gravity of the door body 3 or the action of the urging force on the door body 3.
