ABSTRACT:
A cylindrical cam is obliquely mounted on a drive shaft to be shiftable in the axial direction. The cam and the drive shaft are concentric at the axial center and the eccentricity of the cam increases gradually towards the opposite ends and in opposite phases. A pair of contact members carried by a follower member engage the opposite sides of the cam. As the drive shaft is rotated a reciprocating motion is imparted to the follower member and by shifting the cam in the axial direction the amplitude of the reciprocating motion can be varied.
