Abstract
A massager has a device body, a drive unit housed in the device body, a connecting arm driven by the drive unit, an actuator operating in conjunction with the connecting arm, a space guide, an energy storage part consisting of compression springs for storing energy when compressed by the connecting arm, an energy releasing mechanism for rapidly releasing the stored energy, and an adjusting mechanism for adjusting the energy stored in the compression springs, the actuator being adapted to pat the skin surface plural pieces of the compression springs are connected in series so as to make the patting intensity adjustable discontinuously and to make the overall dimensions smaller. Also, a mechanism for feeding warm air onto the skin surface being patted as necessary in the aforementioned massager is disclosed.
