PROBLEM TO BE SOLVED: To provide an oneway clutch providing an end bearing having a more excellent durability. SOLUTION: An end bearing 1 provided in this oneway clutch is made of a steel plate 11 coated by a coating layer 12 consisting of the mixture of a synthetic resin with a solid lubricant and the thickness of the coating layer 12 is 15μm or more and a diameter direction clearance between the outer periphery surface 7A of an inner ring 7 and the inner periphery surface 1A of the end bearing 1 and the diameter direction clearance between the inner periphery surface 8A of the outer ring 8 and the outer periphery surface 1B of the end bearing 1 are set in a range of 40μm or more and 70μm or less. Thereby, an oil film is easy to form in the diameter direction clearance. As the thickness of the coating layer 12 is set to 15μm or more, the exposure of the steel plate by the wear of the coating layer is not happened, in a prescribed wear endurance test.
