The present invention relates to a door opening/closing apparatus of a chamber. The door opening/closing apparatus of a chamber, allowing a user to easily open and close a door and to manufacture a door at low costs, comprises a door having one side fixed by a hinge and rotating around the hinge-fixed side to open and close the chamber; a gas spring having one end fixed to the chamber and rotating the door at a predetermined angle to open and close the door up to a first open position; a first link member having a lower end fixed to the door and having a predetermined length; and a second link member having a first hinge-fixed part with one end fixed by a hinge to an upper end of the first link member and a second link member having a second hinge-fixed part fixed by a hinge to the other end of the gas spring. A user can manually push the door at the first open position to open and close the door up to a second open position with a small amount of energy, and can manufacture the door at low costs. |
