Claims

[Claims for Utility Model Registration] A door opening/closing device in which a door is attached to a housing so that the door can be opened and closed by four rotation axes, the door being fixed to the housing and perpendicular to the door. a first plate; a second plate having one end vertically and rotatably attached to the first plate by a first rotation shaft; and a second plate having one end attached to the first plate; a third plate vertically and rotatably attached to the second rotation shaft at a position farther from the door than the third plate; one end fixed perpendicularly to the door; It is attached to the other end of the number plate by a third rotation shaft perpendicularly and rotatably to the second plate, and the other end is attached to the other end of the third plate. A door opening/closing device comprising a fourth plate rotatably attached perpendicularly to the fourth plate.
