ABSTRACT:
A massage apparatus performable massaging actions substantially in the same mode as of manual actions by massagers is provided. In driving mechanism for massaging attachments with which massaging force is applied to user's suffering body part, driving and driven side gears are arranged to provide an unequal velocity ratio so that rotating velocity of the driven side gear will be varied as rotated by the driving side gear, whereby the massaging attachments are pushed toward the suffering body part when the velocity of the driven side gear is low and thus with a slowly gradually increased force whereas the pushed attachments are released from the body part when the velocity is high and thus with a quickly decreased force.
