Patent ID: 7032732

Claim:
A two-way clutch comprising: an inner race element provided with one of a cam surface and a cylindrical surface; an outer race element provided with the other of the cam surface and the cylindrical surface; a torque transmission member interposed between said cam surface and said cylindrical surface for effecting torque transmission between said inner race element and said outer race element; biasing means for biasing said torque transmission member in a direction substantially along said cam surface; and a cage for retaining said torque transmission member and said biasing means, the cage being supported to be rotatable relative to said cam surface, wherein said cage is elastically retained by elastic retaining means at a position where said torque transmission member is in a neutral condition with respect to said cam surface, and said biasing means is provided on only one side of said torque transmission member, and wherein an extension portion is formed on said cage to be extending in an axial direction with respect to either said inner race element or said cuter race element, whichever serves as a cam surface side element having the cam surface, and wherein a frictional drive means is interposed between said extension portion and said cam surface side element for frictionally transmitting a rotary force of said cam surface side element to said cage to thereby rotate said cage in a same direction as said cam surface side element, but with a delay relative to said cam surface side element.
