To provide a massager having a new-style drive mechanism producing vibratory deformation in the flexible sleeve of the massager.

The massager is a rod-shaped one having a substantially cylindrical terminal element 1.2 and the flexible sleeve 1.3, which is made of a rubber material and forms the outer surface of the terminal element 1.2, and producing motion on the terminal element 1.2 so as to vibrationally deform the terminal element 1.2 outward and inward in its diametric direction with respect to the axis GL in the longitudinal direction of the terminal element 1.2. The drive mechanism 2 is formed of a plurality of support elements 4 and has a plurality of bearings and support surfaces for supporting the sleeve 1.3 driven by at least one shaft. The support elements 4 are formed of several disc-like jaw elements adjacent to each other along the axis GL in the longitudinal direction or several ball elements arranged along the axis GL in the longitudinal direction and interacts with at least one eccentric part 5' of at least one shaft to produce the advance motion of the stroke of the support elements 4 along the axis GL in the longitudinal direction of the terminal element 1.2.
