It is adapted to press against the body while rotating the loosening roller or the roller, and the latter applies vibration to the contact body to vibrate and loosen a part of the body.

[0003]

By the way, in the conventional massage machine, in the former case, there is a problem that the pressure is too strong during use, sometimes it is entangled in clothes, and it is difficult to obtain a soft feeling. In the latter case, Although a soft feeling can be obtained, the user has to move the massager in order to loosen up and massage a wide area, which causes a problem of increased fatigue.

The present invention has been made in view of the above situation, and an object of the present invention is to provide a soft touch with a pair of fir tree balls and to widely cover not only shoulders, waists but also affected areas such as soles. The purpose of the present invention is to provide a versatile massage machine that can be loosened over a long period of time, prevents the rotation of the fir tree ball, does not have the power cord entangled, and can be operated smoothly.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, according to the present invention, a pair of massage balls provided with a vibrating means are eccentrically mounted in each housing through a crank pin, a spring-made connecting rod and a massage ball rotation preventing means in a housing. In the machine, the chaff rotation prevention means includes a rotation prevention lever having one end rotatably attached to each crank pin, and a lever slide guide member fixed to a housing or the like and for guiding the chaff rotation prevention lever. It is characterized by consisting of and.

[0006]

According to the present invention, by the rotation of the pair of rotating bodies, each fir tree ball moves on a circular orbit centered on the axis of the rotating body.
The rotation prevention means revolves around the earth without rotating, and performs a rubbing operation, and the vibrating means applies vibration to each of the kneading balls. Therefore, vibration acts on the body at the same time as the rubbing motion, and the pressing force is alleviated by the spring connecting rod, the rubbing motion becomes soft, and there is no discomfort such as extreme pressure.
Effective massage can be done over a wide area.

[0007] When the vibrating means is stopped, only the rubbing operation by the fir balls is performed, and conversely when the rotating body is stopped, the fir balls only vibrate, so that three types of massage can be selectively performed.
