Abstract: A self-travelling vibration generator having a travelling frame movably supported by parallel rails, a lifting/lowering frame standing at substantially right angles with respect to the travelling frame, a plurality of eccentric rollers provided off-center with respect to a roller shaft rotatably provided on the lifting/lowering frame; and having such a construction that an induction motor is used for at least either of a motor for travelling the travelling frame or a motor for rotating the roller shaft so as to cause the eccentric rollers to give vibrations to a human body while travelling on the human body.

Abstract: A beauty treatment device having a device body, a drive unit provided in the device body and a patter driven by the drive unit wherein the patter is composed of a freely rotating roller; and freely rotating space guide wheels for maintaining the range of patting motion of the roller by depressing an object being patted, and roller supports disposed on an axis coinciding with the center of the space guide wheels for supporting the shaft of the roller off-center with respect to the space guide wheels, so that the patter pats the object being patted.

Abstract: A beauty treatment device having sharp-edged disc-like wheels, a wheel shaft for supporting the wheels, a device body for rotatably supporting the wheel shaft, a weight, resting on the device body, for giving pushing force to the wheel shaft, a vibration generation mechanism for giving vibration to the wheel shaft, and a travelling mechanism for causing the wheel shaft to rotate is disclosed. The device provides massage by giving vibration to the wheel shaft and causing the wheel shaft to rotate on the axis thereof.
