PROBLEM TO BE SOLVED: To provide a release bearing support structure of a clutch device capable of reducing clutch operation force, by miniaturizing a release bearing by eliminating a bearing retainer. SOLUTION: An inner race 13a of the release bearing 13 is inserted with a clearanceδin the predetermined radial direction into an outer peripheral part of a driven shaft 8, and an abutting part 13a<SB>1</SB>capable of contact in a line with an inner peripheral part side surface of a diaphragm spring 12, is arranged in one end part of the inner race 13. When rocking a release yoke 14, an operation part 14b of the release yoke 14 presses the back of outer races 13b and 13d of the release bearing 13, and reverses the diaphragm spring 12 by moving the release bearing 13 in the axial direction along the driven shaft 8. At this time, since the inner race 13a floats from the driven shaft 8 by being automatically aligned by followably rotating with the diaphragm spring 12, sliding resistance is not generated between the inner race 13a and the driven shaft 8.
