    摘要: A rotating damper (D) has housings (11, 51), a silicone oil (21) received in the housings, a rotor (31) that is received in the housings (11, 51) and where a resistance section (36) moving in the silicone oil (21) is provided on a shaft section (32) projecting from the housings (11, 51), and an O-ring (61) for preventing the silicone oil (21) from leaking from between the shaft section (32) and the housing (51). Arc-like holes (37) are concentrically formed in the resistance section (36), and grooves (38) connecting the arc-like holes (37) are formed. The structure above enables air mixed into the housings not to be excessively compressed during assembly, and as a result, abnormal noise caused by the air mixed in the housing is prevented from occurring even when the rotor is rotated in both directions.
