Patent number: 11415194Abstract: This damper comprises: a housing accommodating a damping medium; and a rotor rotatable relative to the housing, inside the housing. A unidirectional clutch which stipulates rotation in one direction and a rotating shaft can be connected to each other coaxially. The unidirectional clutch, when supporting the rotating shaft, constitutes a first input object, whereas the rotating shaft constitutes a second input object when not being supported by the unidirectional clutch. A connection object comprises a first connection part capable of connecting to the first input object coaxially, and a second connection part capable of connecting to the second input object coaxially. Two separate connection states are provided, namely a state in which the first connection part and the first input object are connected to each other, and a state in which the second connection part and the second input object are connected to each other.Type: GrantFiled: May 18, 2018Date of Patent: August 16, 2022Assignee: NIFCO INC.Inventor: Makoto Muranaka
