Abstract
An electric massage device comprises a motor, a base, at least one gear train including a driven gear rotatably supported in the base, at least one movable member, and at least one massage member. The driven gear is driven by an output shaft of the motor. The driven gear includes engaging grooves in a side thereof. The movable member includes a toothed portion having a plurality of teeth. The massage member is securely connected to the movable member to move therewith. The engaging grooves of the driven gear and the teeth of the movable member are so configured that when the output shaft turns in a direction, the movable member and the massage member are turned, and that when the output shaft turns in a reverse direction, the movable member and the massage member move reciprocatingly.
