Abstract
Massaging element for mechanical massaging device comprises an inner ring fixed eccentrically to a main driven shaft and an outer ring fitted around the inner ring through an antifriction bearing, and the outer ring comprises many arcuate and elastic plate-spring parts extending substantially spirally outward as formed integrally with a ring body and a soft material layer formed around the body embedding therein the plate-spring parts. The element initially provides a soft touch to a human body and then gradually harder touches with the modulus of elasticity increased stepwise, whereby a pressing massage action similar to that manually given by a skilled massagist can be obtained.
