To provide a massage device enhancing massage effect by alternately applying a different amount of a massage action to a part to be massage.

When a part to be massaged is pressed to a ball-like small massage unit 8 and a wheel-like large massage unit 9 in use, the ball-like small massage unit 8 and the wheel-like large massage unit 9 roll on their axis, respectively, and simultaneously revolves and moves to a friction board 4. Thus, the part to be massages is given the massage action from the ball-like small massage unit 8 and the wheel-like large massage unit 9. In this case, the ball-like small massage unit 8 and the wheel-like large massage unit 9 are different in diameter, whereby the different amount of the massage actions are alternately applied to the part to be massaged by a different H in diameter between both rotators 8, 9, so that the effective massage action can be obtained.
