PROBLEM TO BE SOLVED: To provide a clutch release bearing achieving improved sealability, especially improved mud water resistance without increasing a bearing torque. SOLUTION: This clutch release bearing 10 includes: an outer ring 12 forming a rotation side and made to serve as an outer member abutting on the rotary member of a clutch device; an inner ring 11 forming a stationary side and made to serve as an inner member arranged on the inner periphery of the outer ring 12; and a first seal member 15 having an outside diameter end portion fixed to the inside diameter surface of the outer ring 12 and an inside diameter end portion brought into contact with the outside diameter surface of the inner ring 11, and sealing at one end on a rear side an annular space formed between the outer ring 12 and the inner ring 11. The inner ring 11 is provided with a second flange portion 11b extending to an outside diameter side, and an axial seal clearance S2, that is, a non-contact seal, is formed between the second flange portion 11b and the first seal member 15.
