2. Description of the Related Art A conventional electric massager is based on Jitsuko Sho 55-
As shown in Japanese Patent No. 9936, a rotary disk rotated by a motor or the like is provided with a recess, and a massage ball is loosely fitted in the recess.

[0003]

In the above-mentioned conventional massage device, since the massage ball slides in the concave portion, the frictional resistance due to the rotation is large, the massage ball does not slide and rotate, and the massage ball presses against the skin. It had the drawback of scratching the surface of clothes. To make up for this shortcoming,
Although a cream for massage or the like was filled in the concave portion, there was a problem that the massage ball slipped on the skin or the surface of the clothes because of the low contact resistance with the skin or the clothes, which was not effective.

Therefore, the present invention aims to solve the above problems.

[0005]

In order to achieve the above-mentioned object, the present invention provides a plurality of diametrically extending from a vertex of a virtual conical shape or its vicinity along a conical curved surface of the virtual conical shape. A roller shaft having an axis arranged so as to be substantially coincident with virtual radiation is attached to a rotary disk that rotates around the line of rotational symmetry of the virtual cone, and the rotary disk is driven to rotate by a rotary drive mechanism. Further, a substantially wheel-shaped massage roller having a diameter dimension larger than a thickness dimension is rotatably held around the shaft center of the roller shaft and has a portable handle portion.

[0006]

[Function] The user grasps the portable handle portion and applies the massage roller of the rotary disk rotated by the rotary drive mechanism to the body. A roller shaft is attached to a turntable, a massage roller is rotatably held around the axis of the roller shaft, and the shaft center is a plurality of radially extending along the conical curved surface of one virtual cone. Since the massage roller is arranged so as to substantially match the virtual radiation, the massage roller rolls while inclining, giving a complex massage action in the tertiary direction to the body.

Further, since the massage roller has a diameter dimension larger than the thickness dimension, the contact area with the body is small, and therefore the pressing force on the body is strong.

For example, a radial bearing is used for 15, but it is also preferable to use a thrust bearing or the like. When the above-described fan 8 and suction holes 7 are provided, the rotary disk 2 is further provided with a large number of air holes 16 as shown in FIG. To blow out.

In FIGS. 1 and 5, a plurality of virtual radiations B radially extending from the apex G of one virtual cone A along the conical curved surface of the virtual cone A are substantially matched. The roller shafts 1 have the axes L. In this embodiment, the axis L of the roller shafts 1 ... Is eccentric from the virtual radiation B ... by an angle β as shown in FIG.
Here, the angle β is preferably set to 20 ° or less. In particular, β should be set to 5 ° to 10 °. Note that β = 0 ° is also free.

In FIG. 1, the turntable 2 rotates about a line of rotational symmetry C of a virtual cone A. The roller shaft 1 ...
Are attached to the turntable 2. Further, the massage rollers 4 are held rotatably around the axis L of the roller shafts 1. Here, the massage roller 4 has a substantially wheel shape, and the diameter dimension D is set to be sufficiently larger than the thickness dimension T. The roller shafts 1 ... Can be fixed to the turntable 2 so that the massage rollers 4 ... Can rotate with respect to the roller shafts 1 ...
Can be fixed or integrated so that the roller shafts 1 ... Can rotate with respect to the turntable 2, or both the massage rollers 4 ... And the roller shafts 1 can rotate. The massage rollers 4 ... Are made of, for example, plastic, hard or soft rubber, or the like.

Since the rotation axis L of the massage rollers 4 is inclined in this way, the outer periphery of the rotation locus of the massage rollers 4 (when the rotary disk 2 is rotated by the rotary drive mechanism 3) is used. From the vicinity of the head outer peripheral wall 18 of the body cover 9 to the outside. That is, the outermost locus of the massage rollers 4 can be drawn large. Therefore, when massaging a hard-to-reach shoulder or the like, the massage rollers 4 can be applied well to the shoulder or the like, that is, there is an advantage that it is easy to apply.

In such an electric massager, a breathable soft cover 14 shown in phantom in FIG. 1 is provided at the tip opening of the main body cover 9 for the rotary disk 2 and the massage roller 4.
