ータリーダンパ。[Claims for Utility Model Registration] A sealed liquid chamber formed by a bottomed cylindrical synthetic resin casing and a cap for closing its opening is urged to rotate by an external force via a rotor shaft. In a rotary damper installed so that the rotor receives liquid resistance, an O-ring is interposed between the cap and the rotor shaft to connect the two so that they do not come into direct contact, and also to connect the periphery of the casing and the cap to A rotary damper characterized by being liquid-tightly fixed by ultrasonic welding.
