In FIG. 12, the locking receiving means (81) is a pin that engages with the groove of the grooved ring. When the massaging massage is performed, the second treatment finger body (86) receives a force in the direction of the arrow in FIG. When this force acts beyond the biasing force of the elastic means (85), the elastic means (85) contracts and moves in the direction of the arrow. When the second treatment finger (86) moves by a predetermined amount or more, the grooved ring engages with the pin, and the rotation of the second treatment finger (86) is prevented. During the massage massage, the second treatment finger (72) does not rotate, so that an effective massage massage can be performed.

When the second treatment finger (72) separates from the user (99), the second treatment finger (72) returns to the original position by the elastic means (85).

When performing a rolling massage,
The second treatment finger (72) receives a force in the direction of the dashed line arrow in FIG. For this reason, the force in the direction of contracting the elastic means (85) does not act as described above. Therefore, the second treatment finger body (86) remains free to rotate with respect to the bush (82), and a smooth rolling massage can be performed.

[0027]
