An anti-reverse input clutch is provided which includes an output member including an output shaft held so as to be rotatable about the axis of an input member, and a cam member which is a separate member from the output shaft and on which cam surfaces are formed. The cam member is rotationally fixed to the output shaft. Thus, each of the output shaft and the cam shaft can be easily formed, so that it is possible to significantly reduce the time and cost for manufacturing the output member and improve the freedom of design thereof.
