調節手段を設けたことを特徴とするダンパ機構。[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 check valve that prevents damper oil from flowing into the valve passage provided on the piston when the door is closed, and a governor that limits the flow rate of damper oil that passes through the regulating passage provided on the piston side to adjust the door closing speed. In the damper mechanism, the upper part of the adjusting rod is slidably inserted into the slide hole provided in the rotating shaft, and a spring is inserted into the sliding hole in the rotating shaft to push the regulating rod upward. A temperature-sensing section that accommodates a solid solution that expands and contracts with temperature changes is arranged in the rotating shaft, a membrane section that moves due to the expansion action of the solid solution in the temperature-sensing section, and a movement of the membrane section side. 1. A damper mechanism comprising: an adjusting means having a movable shaft that is pressed down by an action to push down the speed regulating rod against the elastic force of a spring.
