In a massage machine, a massage mechanism portion (100) has a first up/down motion mechanism portion for converting the rotation of a drive motor (M11) into motion in the up/down directions to cause a rear portion of a treatment-member tie (5) to move up and down, a second up/down motion mechanism portion for converting the rotation of a drive motor (M12) into motion in the up/down directions to cause portion between a front and a rear portion of the treatment-member tie (5) to move up and down, and a left/right motion mechanism for converting the rotation of a drive motor (M13) into motion in the left/right directions to cause the treatment-member tie (5) to move in the left/right directions. Forward and backward pushing motion by a treatment member (4) is performed by repeating the motion of the treatment-member tie (5) in the up/down directions performed by the drive motors (M11, M12) and the first or the second up/down motion mechanism portion. Further, sandwiching motion is performed by repeating the motion of the treatment-member tie (5) in the left/right directions performed by the drive motor (M13) and the left/right motion mechanism portion. Operation of changing a treatment position in the up/down directions is made by the cooperative rotation of the drive motors (M11, M12).
