As the sensor provided on the width drive unit 3, the sensor 6b for driving the speed of the massage head 1 driven by the unit 3 is provided with only the sensor 5c for detecting the vertical position of the massage head 1 generated by the vertical drive unit 4 as the -18. - 1277409 Description of the invention A case of a sensor provided on the upper and lower drive unit 4 will be described. Since the strong and weak driving unit 2 is configured to swing the massage head 为 around the fulcrum, the movement of the massage head 产生 by the strong driving unit 2 can be moved not only in the longitudinal direction of the human body but also in the vertical direction of the human body. In the fifth embodiment, it is not necessary to provide a sensor for detecting the speed on the vertical drive unit 4. In order to control the position in the vertical direction, only the sensor 5c for detecting the required vertical position can be used, and the control is not complicated, and the structure can be simplified. . Here, as described above, since both sides of the movable range in the width direction of the massaging head arm 8 of the massaging head 1 driven by the width driving portion 3 are provided, 1〇 has a strong and weak driving for driving the pair of massaging head arms 8. Since the gear 9 is used, the massage head 1 can be driven by the strong and weak drive mechanism to drive the massage head arm 8 in a strong manner, and the transmission can be performed at a high speed by the strong drive gear 9 . Further, as in the embodiment shown in the drawings, when the massage head 1 is provided with a pair in the left-right direction, even when a load is applied to only 15 pairs of massage heads, a twisting force is generated in the branch portion due to the load. Both ends of the support portion are supported by the j-knife of the strong-low drive gear 9, so that the shaft is not bent, and even in this respect, the strong-drive mechanism can be driven to strongly drive the massage head arm 8. As described above, since the strength-lowering gear 9 is formed only by the arc-shaped gear having the gear on the portion 20 necessary for driving the strong and weak arms of the massage head arm 8, the thickness of the massager can be thinned, so that the whole can be achieved. Small plasticization. Further, the pair of arc-shaped gears 9a are formed to be bilaterally symmetrical with respect to the rotational axis of the massaging head arm 8 (in the example of the embodiment, the width drive shaft 1G becomes the center of rotation of the massaging head arm 8), and a pair of left and right circles are formed.
