PROBLEM TO BE SOLVED: To suppress the generation of noise by absorbing vibration which is applied to column parts of a control holder and a rotating holder at the changeover of a two-way clutch.SOLUTION: A holder of a two-way clutch 10 which is controlled in engagement and release of the engagement by an electromagnetic clutch, and performs the transmission and block of rotation between an input shaft and an output shaft is formed of a control holder 16A which is moved to an axial direction by the electromagnetic clutch, and a rotating holder 16B. Column parts 22, 26 which are formed at external peripheral parts of the control holder and the rotating holder are alternately aligned in a circumferential direction between an outer ring 11 and an inner ring 13, and a pair of rollers 15 and an elastic member 20 are assembled into a pocket 27 between the adjacent column parts. Forked pieces 22a, 22b, 26a, and 26b are arranged at the column part of the control holder and that of the rotating holder, respectively, by forming slits 35 which extend from a tip face toward the axial direction, vibration is thereby absorbed by the elastic deformation of one set of the pieces 22a, 26a which oppose the rollers when the column parts vibrate by a collision of the control holder with an opening end face of the outer ring 11, and the generation of noise is suppressed. |
