Abstract:
A plurality of accommodation holes (120) are formed in an input shaft (11) and/or an output shaft (12). Cam-urging mechanisms (80) have springs (81) and contact members (82) that come into contact with cam surfaces (71) of sliders (41, 42). At least part of the contact members (82) are accommodated in the accommodation holes (120). In a cross section orthogonal to an axial direction X, if both ends of opening parts (120c) of the accommodation holes (120) formed in the outer circumferential surface of the input shaft (11) or the output shaft (12) are respectively designated as opening edges (120a, 120b), the plurality of accommodation holes (120) are formed such that the length of first arcs (L1), which are the arcs between the opening edges (120a) and the opening edges (120b) adjacent in the circumferential direction of the outer circumferential surface and which include any opening parts of the plurality of accommodation holes (120), is greater than the length of second arcs (L2), which are the arcs of the opening edges (120a, 120b) at both ends of one accommodation hole (120).
