Document Type and Number:
WIPO Patent Application WO/2023/276715
Kind Code:
A1
Abstract:
A torque cam (2) comprises: an annular driving cam (40) that relatively rotates with respect to a housing (12) when a torque from an electric motor (20) is input; a driven cam (50) that relatively moves with respect to the housing (12) in the axial direction when the driving cam (40) relatively rotates with respect to the housing (12); and cam rolling elements (3) that roll between the driving cam (40) and the driven cam (50). The driving cam (40) has a driving cam groove (400) formed to extend in the circumferential direction of the driving cam (40) so that the cam rolling elements (3) can roll therein. A thrust bearing (16) is provided such that, as viewed in the axial direction, the center position (P1) in the radial direction of the thrust bearing (16) is located on the radially inner side of a pitch circle (Cp1) passing through the center position (P3) of the driving cam groove (400) in the radial direction of the driving cam (40).
