Abstract
Abstract A massage apparatus having a vibratory massage plate, the vibratory motion of which is derived from a drive unit rotated by an electric motor and an insertable portion of a drive shaft in operative engagement with the drive unit. In order to perform underwater massage in addition to dry vibration massage, the invention provides for a container having a drive shaft rotatably mounted in its bottom portion. The drive shaft has an impeller or the like mounted thereon inside the container and has an insertable portion on the shaft projecting from the underside of the container bottom. The massage plate has an opening in the area of the drive unit to receive the insertable portion of the drive shaft, and on insertion of the insertable portion of the drive into a receptacle of the drive unit, an operative engagement between the insertable portion of the drive shaft and the drive unit is established. Disengagement of the drive unit and the insertable portion of the drive shaft is effected by axial movement of the drive unit.
