Claim 2:
3. The clutch device according to claim 1, wherein:
in each of the plurality of drive cam grooves, a ratio between a tangent value of the slope angle of the groove bottom relative to a circumferential movement distance from the corresponding drive cam specific point at the emergency-time drive cam groove and a tangent value of the slope angle of the groove bottom relative to a circumferential movement distance from the corresponding drive cam specific point at the normal-time drive cam groove is 1:2; and
in each of the plurality of driven cam grooves, a ratio between a tangent value of the slope angle of the groove bottom relative to a circumferential movement distance from the corresponding driven cam specific point at the emergency-time driven cam groove and a tangent value of the slope angle of the groove bottom relative to a circumferential movement distance from the corresponding driven cam specific point at the normal-time driven cam groove is 1:2.
