|Title:||CAM MECHANISM AND CLUTCH DEVICE USING SAID CAM MECHANISM|
A cam mechanism (1), which is used in combination with a clutch (107) for transmitting torque between a first rotating member and a second rotating member, is provided with: a cam ring (5), which forms an annulus around a shaft and in which one surface of the annulus that faces the axial direction is provided with multiple cam surfaces (3), which are side-by-side in the circumferential direction and each of which is inclined in the circumferential direction with respect to a circumferential plane that is orthogonal to the shaft; a pressure ring (9), which is adjacent to said surface of the cam ring (5) in the axial direction, is provided with multiple cam surfaces (7) that face said surface of the cam ring (5) and are symmetric with the multiple cam surfaces (3) of the cam ring (5), and is capable of rotating relative to the cam ring (5) around the shaft; and multiple tapered rollers (11), which are interposed between the cam ring (5) and the pressure ring (9), have respective conical surfaces that taper inward in the radial direction, and are capable of rolling on the cam surfaces (3,7).
