Abstract
A first drive shaft having a pair of eccentric shaft portions at its middle part and a second drive shaft on which a pair of eccentric cum bodies having eccentric cum portions are provided, are provided in a holding body. A pair of arms are provided on the eccentric shaft portions of the first drive shaft so as to freely oscillate and main massage rollers are provided on each of the arms. The kneading movement is assigned to the main massage rollers by a drive mechanism by selectively rotating the first drive shaft or the second drive shaft. Each arm is composed of an arm housing having a first opening portion, and an arm cover which forms a holding portion having a second opening portion, being bonded to the arm housing and holding a slider so as to freely slide between the bonded surfaces.
