Classification: CPC F  H | IPC F

Claim 7:
8. The rolling element cam according to claim 1, wherein:
each of the plurality of drive cam grooves has an emergency-time drive cam groove that extends toward the one side in the circumferential direction of the drive cam from a drive cam specific point, which is set at another end of the drive cam slope groove that is opposite to the drive cam connection groove at the drive cam groove;
the groove bottom at the emergency-time drive cam groove of each of the plurality of drive cam grooves is sloped relative to the one end surface of the drive cam such that the depth of the groove bottom at the emergency-time drive cam groove continuously decreases from the drive cam specific point toward the one side in the circumferential direction of the drive cam;
the slope angle of the groove bottom at the emergency-time drive cam groove of each of the plurality of drive cam grooves relative to the one end surface of the drive cam is smaller than the slope angle of the groove bottom at the drive cam slope groove relative to the one end surface of the drive cam at the drive cam groove;
each of the plurality of driven cam grooves has an emergency-time driven cam groove that extends toward the one side in the circumferential direction of the driven cam from a driven cam specific point, which is set at another end of the driven cam slope groove that is opposite to the driven cam connection groove at the driven cam groove;
the groove bottom at the emergency-time driven cam groove of each of the plurality of driven cam grooves is sloped relative to the one end surface of the driven cam such that the depth of the groove bottom at the emergency-time driven cam groove continuously decreases from the driven cam specific point toward the one side in the circumferential direction of the driven cam; and
the slope angle of the groove bottom at the emergency-time driven cam groove of each of the plurality of driven cam grooves relative to the one end surface of the driven cam is smaller than the slope angle of the groove bottom at the driven cam slope groove relative to the one end surface of the driven cam.
