1. A massager having a device body, a drive unit housed in said device body, a connecting arm driven by said drive unit, energy storage means comprising at least two compression springs connected in series for storing energy when compressed by said connecting arm driven by said drive unit, energy releasing means for rapidly releasing the energy stored in said energy storage means, an actuator driven by said energy storage means and said energy releasing means, a plate member mounted on said actuator, a space guide mounted on said device body for defining an area through which said plate member can travel, and adjusting means for adjusting the amount of energy stored in said energy storage means, characterized in that said adjusting means is constructed so as to adjust the amount of energy stored in said energy storage means and limit the amount of energy stored in at least one of said springs to a predetermined value, said plate member being caused to move to a location apart from a skin surface essentially in contact with said space guide in a state where energy is stored in said energy storage means, and said plate member hits against said skin surface when the energy thus stored is released by said energy releasing means, whereby patting action is repeatedly effected by said plate member onto the skin surface, said actuator being constructed of a retractable rod member, said adjusting means having a spring compression portion, an intermediate spring seat movable in said body and slidably supported by said rod-shaped actuator and connecting said at least two compression springs in series;

  • one end of said compression springs connected in series being supported by said connecting arm and the other end therof by said spring compressing portion; and

    said compression springs being adapted to be compressed between said connecting arm and said spring compressing portion of said adjusting means when said connecting arm is driven.
