摘要： A damper device includes a cylinder body and a piston body, and at least one of the cylinder body and the piston body is adapted to attach to an object to be damped for damping a movement or a relative movement of the object to be damped. A communication hole which communicates inside and outside of the cylinder body is formed in an inner back portion of the cylinder body. Also, a valve body is provided for reducing a flow volume of a fluid passing through the communication hole by moving from a standard position while elastically deforming at least one portion due to a pressure change caused by the movement or the relative movement of the piston body.

摘要： A rotary damper is provided so that air incorporated into a housing during assembly is, not excessively compressed, whereby a generation of a peculiar sound due to the air incorporated into the housing can be prevented even though the rotor rotates in both directions, and so that the air is stopped and captured in a fixed place whereby influence on the generated torque can be reduced, and irregularity of the torque can be reduced progressively.A rotary damper includes a housing (11, 51), silicon oil housed inside the housing (11, 51), a rotor 31 housed inside the housing (11, 51), and having a shaft member (32) projecting from the housing (11, 51) and having a resistance member (36) moving through the silicon oil (21) inside the housing (11, 51), and an O-ring (61) for preventing leakage of the silicon oil (21) from between the shaft member (32) and the housing (51). A circumferential groove (54) is provided on an inner face of the housing (51) facing the resistance member (36).
