DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massager of the type which reciprocates a massage means for massaging a user.

[0002]

2. Description of the Related Art In general, this type of massaging apparatus is provided with a holding body holding a massaging roller in a base body having an opening at an upper surface and covering this opening with a cover, and the holding body is movably provided. By moving the body back and forth by the driving means, the user lying on the cover is massaged by the massager.

[0003] The massage device includes a mattress type,
There is a chair type. Usually, in the former case, two holding bodies are provided at a predetermined interval in the running direction, and in the latter case, one holding body is provided to be able to run freely.

In any case, a plurality of mass rollers are rotatably supported on the holder at predetermined intervals in the width direction which intersects at least the running direction of the holder. . These mass-rollers run while pressing both sides and legs of the spine on the back of the user.

By the way, the back and legs of the user pressed by the mass-roller are not flat, but are curved in the width and height directions. The degree is larger than other parts. The curved part is attached to the holder,
When the massaging is performed simply by a rotatably provided massaging roller, only a part of the plurality of massaging rollers strongly hits the back surface of the user, and the remaining massaging rollers hardly hit the massaging roller. Something like that.

For this reason, the massaging roller does not reliably hit the constricted portion of the waist, the depressed portion on both sides of the spine, or the curved leg portion with a predetermined pressing force, so that a sufficient massaging effect is obtained. Not only is it not possible to obtain, but also the protruding part may be so pained that Massa-Girola hits it too strongly.

In order to improve the massaging effect of the massaging roller, a plurality of projections are provided on the outer peripheral surface at predetermined intervals along the circumferential direction so that the body of the user can be pressed strongly. I have to.

However, even if a projection is provided on the outer peripheral surface of the disk-shaped mass-roller, since the outer peripheral surface is curved at a predetermined curvature, the plurality of projections are pressed against the user with the same pressing force. Can not do. Therefore, Massa-jiro-
Even if a projection is provided on the outer peripheral surface of the rubber, the massage effect may not be sufficiently enhanced.

[0009]

As described above, in the conventional massaging device, the massaging roller is merely rotatably provided on the holding body, so that the massaging roller strongly hits the back surface of the user. In some cases, a good massage effect could not be obtained because of too much or insufficient contact.

The present invention has been made based on the above circumstances, and an object of the present invention is to ensure that a curved back surface of a user can be securely massaged with substantially uniform strength over the entirety. The object of the present invention is to provide a massage device capable of improving the effect of the massage.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a base, and is provided so as to be able to run along a predetermined direction of the base and is installed along the width direction of the base. A holder having a support shaft, a driving unit for reciprocating the holder along a predetermined direction of the base, and both directions of the running direction and the direction intersecting the running direction of the holder on the support shaft of the holder. And a massage belt provided with a plurality of projections protruding at predetermined intervals on an outer peripheral surface thereof and provided on the mounting body so as to be able to run endlessly. I do.

[0012]

According to the above construction, the massage belt is swingable with respect to the holder in the running direction and in a direction intersecting the direction, and the movable body provided with the massage belt is also a movable member provided with the massage belt. Since the massage belt is swingable with respect to the support shaft, the massage belt can easily swing even with a slight curved shape on the back surface of the user.
