Claims

[Scope of Claim for Utility Model Registration] A hinge cylinder whose internal oil chamber is filled with damper oil, a bearing attached to the hinge cylinder, a rotating shaft rotatably inserted through the bearing, and a rotating shaft inserted into the hinge cylinder. a piston spline-engaged with the distal end side of the rotating shaft and screwed into the hinge cylinder;
A damper mechanism comprising a check valve that prevents damper oil from flowing in from a valve passage provided in the piston when the door is closed, and a speed regulating means provided in the regulating passage of the piston, wherein the regulating means comprises: A temperature-sensing section that accommodates a fluid that expands and contracts with temperature changes, a membrane section that is pushed by the expansion action of the fluid within the temperature-sensing section, and a pushing motion of the membrane section that causes the speed regulating passage to be closed. The movable part has a tapered tip that slides forward inside the damper, and the movable part slides as the outside temperature changes to control the flow rate of damper oil passing through the regulating passage. damper mechanism.
