Abstract: There is disclosed a bi-directional clutch which offers improved reliability. The three main elements are (a) a stationary, planar section having an upstanding circumferential wall, (b) a driving member having a rotatable planar section and an upstanding cylindrical wall around a central bore, the wall having radial slots and being positioned within the circumferential wall of the stationary member, and (c) a hexagonal-shaped member which is to be driven by the driving member, positioned in the bore of the driving member. A plurality of hollow cylindrical rollers are positioned within the slots of the driving member; opposite ends of each roller are adjacent to the planar surfaces of the stationary and driving members. A torque applied to the driving member, in either direction, causes the rollers to move and to bear against the hexagonal-shaped member to drive it.
