Claims (1)

[Claims for Utility Model Registration] A first rotating shaft equipped with a cam and a second rotating shaft equipped with a cam follower are rotatably supported by a housing via rolling bearings, and the cam and the cam follower are engaged with each other. , in an inconstant speed rotation device that converts constant speed rotation of the first rotation shaft to inconstant speed rotation such as intermittent rotation or reciprocating rotation of the second rotation shaft, wherein the first rotation shaft and the second rotation shaft A small inconstant velocity characterized in that an annular member is closely fitted to at least one outer circumferential surface and abuts on the inner ring of the rolling bearing, so that thrust load is transmitted to the rolling bearing via the annular member. Rotating device.
