Abstract:
A two-way clutch unit comprising an input system rotating member driven and rotated by a drive source, an output system rotating member for outwardly taking out torque transmitted from said input system rotating member, a torque transmission member interposed between said rotating members and being selectively engageable with and disengageable from both rotating members, and a cam mechanism for controlling said engagement and disengagement of said torque transmission member through relative angular displacement with respect to said input system rotating member, said cam mechanism being coupled to said input system rotating member using shearing resistance of a viscous fluid therebetween, wherein the torque transmission member is able to transmit torque in either of normal or reverse direction when the same is engaged with said input system rotating member, and said output system rotating member is freely rotatable only when the torque transmission member is disengaged from both the rotating members.
