WIPO Patent Application WO/2016/114327
Kind Code:

Abstract:
Provided is the structure of a cam device in which a drive-side cam can be effectively prevented from rotating relative to a driven-side cam in a locked state. Tip-abutting parts (63) are provided to the outside-diameter portions of tip surfaces (41a (40a)) of either the drive-side convex parts (34a) of a drive-side cam surface (31a) or driven-side convex parts (36a) of a driven-side cam surface (32a), and tip concave parts (64) depressed in the axial direction lower than the tip butt-welding parts (63) are provided to the inside-diameter portions of the convex parts that have the tip-abutting parts (63). In a locked state, only the tip abutting parts (63) abut the tip surfaces (40a (41a)) of the drive-side convex parts (34a) or the driven-side convex parts (36a) that do not have the tip-butting parts (63).
