SUMMARY OF THE INVENTION In the above-mentioned conventional apparatus,
A heavy motor 44 and a reduction gear 45 are collectively arranged on one of the support legs 40. Therefore, when the handle 41 is gripped and held, the center of gravity is shifted toward one of the support legs 40, so that the usability is poor. For example, the burden weight becomes abnormally large depending on the gripping position of the handle 41, the gripping hand becomes fatigued in a short time, or it is difficult to perform a massage operation in a location where the hand is hard to reach. Since the speed reducer 45 is arranged on the extension of the rotation center axis of the massage body 43, the overall left and right dimensions also become large, which is also inconvenient.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hand-held massage machine which can reduce weight and at the same time, can be reduced in size and improved in usability.

[0006]

According to the massage machine of the present invention, a hollow support arm 6 is protruded from both ends of a hollow cylindrical grip 3, and a rotary roller type massage body is provided between the two support arms 6. 2 is rotatably supported, and the massage body 2 is rotationally driven by a motor 19 and a reduction gear 20 built in the grip 3 via a transmission mechanism 21 provided inside one support arm 6. Requirements.

[0007]

The motor 19 and the speed reducer 2 are provided inside the grip 3.
Since 0 is arranged, the center of gravity of the massage machine approaches the hand. Furthermore, the support arm 6 only needs to have a lateral width enough to accommodate the transmission mechanism 21, and even if the pair of support arms 6 are formed symmetrically, the lateral dimension of the massage machine can be made sufficiently smaller than that of the conventional device.

[0008]

According to the present invention, a hollow cylindrical grip 3 is provided.
, A motor 19 and a speed reducer 20 which are heavy were arranged in the inside thereof, and the center of gravity of the massage machine was brought close to the hand. Therefore, the weight can be prevented from being lifted when the handheld device is used while holding the grip 3, and the massage machine can be handled easily and without fatigue. Further, the reducer 20 and the motor 19, which have a large left-right width, are housed in the grip 3 to reduce the left-right dimensions of the massager as a whole, thereby making it possible to reduce the size by that much, so that the above weight can be eliminated. It is also convenient to carry and can improve usability.
