Claims

[Scope of utility model registration request]

A separate block is provided inside the casing, and a hollow shaft with a vane installed in the center of the separate block is rotatably inserted. In a rotary damper, oil in one oil chamber expands through a gap with the inner periphery of the oil chamber and flows into the other oil chamber, which contracts and provides damping torque.In a rotary damper, the shaft is provided with ports that communicate with each oil chamber, and A rotary damper characterized in that a hollow rotary valve is rotatably inserted into the rotary damper, and the rotary valve is formed with an orifice that opens and closes at each of the ports.
