Abstract: A cylinder body is partitioned by a partition into a first chamber that is divided from an outside by a cap body and a second chamber accommodating a piston body. A flow channel communicating the first chamber and the second chamber with each other is formed in the partition, and a shaft is projected from the partition onto the first chamber side. The cap body includes a through-hole, the shaft is inserted movably in the through-hole from a reference position along an axis line direction of the cylinder body. There is provided a throttle structure that changes a gap between the through-hole and the shaft when the cap body moves from the reference position by a pressure change generated by a movement or a relative movement of the piston body.

Abstract: 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).
