Claims

[Scope of utility model registration request]

an input shaft rotatably supported in the housing;
A roller gear cam is fixed to the input shaft and has a tapered rib forming a predetermined geometric curve on the outer peripheral surface and an endless groove cam forming a predetermined geometric curve on one end surface; an output shaft that is arranged to intersect at right angles and is pivotally supported by the housing so as to be rotatable forward and backward and slidable in the axial direction; a spline shaft portion having a square cross section integrally formed with the output shaft; , a follower turret that is coaxially and slidably fitted directly to the spline shaft portion and rotatably supported by the housing while being restricted from moving in the axial direction;
A cam follower is provided on the outer peripheral surface of the follower turret and engages with the tapered rib cam of the roller gear cam, a fulcrum part is rotatably supported on the housing, and a force point part is engaged with the groove cam of the roller gear cam. A cam device comprising: a swinging arm having a point of action that engages with a groove formed in an outer circumferential portion of the output shaft.
