Claims

[Scope of utility model registration request]

(1) In a door opening/closing device in which a door and a main body are connected by a hinge part and a pin, and the door is closed in a fixed position by a stopper provided on the main body side, the pin hole and pin of the hinge part are formed into a polygonal shape. At the same time, one or both of the polygonal corners are made elastically deformable or displaceable, and when the hinge part or pin rotates and the door hits the stopper, the stopper hits the stopper at this location. A door opening/closing device characterized in that the pin hole and the corner of the pin are shifted from each other so that force is applied.

(2) Utility Model Registration The door opening/closing device according to claim 1, wherein the hinge portion is provided on the door side, and the pin is protruded from or fixed to a support provided on the main body side.

(3) Utility Model Registration The door opening/closing device according to claim 2, wherein each of the polygonal shapes is square.

(4) Utility model registration Claim 3, wherein the door is characterized in that the hinge portion has a slit that reaches a pit hole at an appropriate position so that the rectangular corner portion can be elastically deformed. Switchgear.

(5) Utility model registration Claim 3, wherein the pin is made of a solid material, and a cross-shaped cut is made along the longitudinal center line of the solid material to form a corner of the square shape. A door opening/closing device characterized by being elastically displaceable.

(6) Utility model registration Claim 3, wherein the pin is made of a shaped material with an opening in cross section, and vertical cuts are made in appropriate places in the shaped material so that the rectangular corners can be elastically deformed. A door opening/closing device characterized by:
