  As shown in FIG. 1, the roller massager 1 configured as described above has the distal ends of the left and right rollers 6 and 6 closest to each other with the rollers 6 and 6 closest to the handle 2. Then, as shown in FIGS. 3, 8, and 9, the tip portions of the rollers 6 and 6 are separated from each other as the tip portions of the rollers 6 and 6 are rotated away from the handle 2.

The roller connecting portion 5 is fixed by fitting the protrusions 18 and 18 with any of the grooves 10a to 10c. Combined with the collision between the flange 11b and the convex portion 20 and the subsequent collision between the flange 11c and the convex portion 20, the ridges 18 are sequentially formed from the groove 10a with the rollers aligned to the groove 10c and the groove 10b. Mating.
When the protrusions 18 of the left and right roller connecting portions 5 are respectively fitted in the grooves 10a, the left and right rollers 6 are arranged in a state where two rollers are aligned below the handle 2 (FIG. 1). Compact and convenient for accommodation.
Further, in this state, when a flat portion such as the abdomen, back, cheek or the like is contacted and the handle 2 is gripped and the rollers 6 and 6 are rotated, the points are pushed by the corners of the rollers 6 and 6, and then the roller 6 , 6, a massage (tapping) is performed in which a light blow is applied to a predetermined part of the body when moving to the flat part.

When the protrusions 18 and 18 of the left and right roller connecting portions 5 and 5 are respectively fitted in the grooves 10c, the left and right rollers 6 and 6 shown in FIG. 8 are rotated by about 135 ° from the state immediately below the handle 2, respectively. Thus, a predetermined angle between the left and right rollers 6 and 6 is expanded. In this state, when a thin curved surface portion such as an arm, ankle, chin, or neck is contacted and the handle 2 is gripped and the rollers 6 and 6 are rotated, the following massage effects are added in addition to the acupuncture and tapping.
When the rollers 6 and 6 are in a state where the rollers 6 and 6 are expanded at a predetermined angle (in the shape of a letter C), the rollers 6 and 6 are brought into contact with a predetermined part of the body and moved in the direction of gripping the handle, so Add a movement to pinch. On the contrary, if it is moved in the pushing direction, a movement to spread toward the roller side is applied to the skin between the roller 6 and the spherical body 7a.

  When the protrusions 18 and 18 of the left and right roller connecting portions 5 and 5 are fitted in the grooves 10b, the left and right rollers 6 and 6 shown in FIG. 9 are rotated by about 160 ° from the state directly below the handle 2, respectively. Thus, the gap between the left and right rollers 6 and 6 expands by a predetermined angle (larger than the above-mentioned state where it has rotated about 135 °). In this state, when it comes into contact with a thick curved part such as a stomach, thigh, calf, etc., and when the handle 2 is gripped and the rollers 6 and 6 are rotated, the massage effect (pinchs the skin) similar to the above-mentioned rotation of about 135 °. Exercise and exercise to spread the skin).

In the present invention, the spherical body 7a is attached to the central portion of the roller mounting member 4, the base portions of the rollers 6 and 6 are separated from each other, and two gaps 30 are formed between the rollers 6 and 6 and the spherical body 7a.
As the roller 6 rotates, a movement to pinch the skin and a movement to spread the skin in the gap 30 occur. Compared to one with a gap, a wide range of massage is possible.
In addition, since the roller massager 1 is made of a rust-resistant metal or plastic, there is no rusting part, and the roller massager 1 can be used in a place where it gets wet with water such as in a bathtub.

  In the above embodiment, the left and right rollers 6 and 6 are rotated by the same angle, but can be rotated at different angles (FIG. 10). Since the distance between the rollers 6 and 6 changes, it can be arbitrarily selected according to the body part to be massaged.

Moreover, in the said embodiment, although the rollers 6 and 6 are regular octagonal columnar shape, they can be replaced | exchanged for the roller of various shapes as shown in FIG.
To replace the roller 6, remove the roller mounting plate 23, then remove the roller 6 from the roller connecting portion 5, attach the desired roller 6 to the roller connecting portion 5, and screw the screw portion 23 a into the screw hole of the arm portion 12. The roller mounting plate 23 is fixed by screwing.
The regular hexagonal columnar shape shown in FIG. 11A has a larger step between the corner portion and the plane portion than the regular octagonal columnar shape, and a strong tapping effect is obtained.
In the case where a plurality of projections 24 are attached to the cylindrical side surface (skin contact surface) shown in FIG. 11B, the projection 24 performs a massage that pushes the acupuncture points as the roller 6 rotates.
In the case where the spiral groove 25 is formed on the cylindrical side surface (skin contact surface) shown in FIG. 11 (c), the spiral groove 25 performs a massage that lightly twists the skin as the roller 6 rotates.
When the top and bottom surfaces shown in FIG. 11 (d) are star-shaped, the corners are acute and the effect of pressing the acupoint is improved.
A shape in which a plurality of octagonal rings shown in FIG. 11 (e) are rotated by 22.5 ° and connected to each other has lighter acupoint pushing and tapping effects than a regular octagonal columnar shape.

FIG. 12 is a perspective view of a roller 6 according to still another embodiment. The octagonal ring is rotated by 22.5 ° to connect an odd number of 3 or more, and every other part corresponding to the octagonal ring plane part at both ends is made flat. A plate material 27 containing germanium and a plate material 28 containing platinum are fixed to the flat portion 26.
The plate material 27 containing germanium and the plate material 28 containing platinum are alternately fixed to the flat portion 26 one by one. Alternatively, the two flat portions 26 may be fixed side by side.
The skin-beautifying effect of germanium and platinum is added to the effect of pressing and tapping by the roller 6.
In addition, it may replace with the board | plate material containing germanium or platinum, and may stick the board | plate material which consists of other raw materials, such as titanium which can anticipate the skin beautifying effect.

Next, another embodiment will be described.
In this embodiment, as shown in FIG. 14, the point which made the radial groove | channels 10d and 10e of the annular member 8 with a groove | channel into 2 stripes is a big difference with the said embodiment.
Two left and right rollers 6 and 6 are aligned below the handle 2 (FIG. 1), and the front ends of the left and right rollers 6 and 6 project forward from the handle 2 to form a C shape (FIG. 8). Any one of the rollers 6 and 6 can be rotated to be deformed into an L-shaped state (FIG. 10) that is not below the handle 2.
Compared to the above embodiment, the position where the roller connecting portion 5 is fixed is less, but even if a force is applied in the direction of gripping the handle 2 and pressing it against the skin during the treatment, the protrusion 18 of the roller connecting portion 5 remains on this wall. Since it is pressed in the direction of hitting, it does not move to the adjacent groove. Therefore, the roller connecting portion 5 does not move to another position when used in an appropriate method, and the massage can be continued in a stable state.

In each of the above embodiments, the spherical body 7a is attached to the central portion of the roller mounting member 4. However, the present invention is not limited to this, and the spherical body 7a may not be provided.
However, the acupoint pushing effect by the spherical body 7a is added by attaching the spherical body 7a. Furthermore, a movement to pinch and a movement to spread in the gap with the roller 6 occurs, and a wide range of massage can be performed.
Moreover, the structure which connects the roller 6 so that angle change is possible, and can fix it at several angles is not restricted to the said embodiment, Various well-known structures may be sufficient. For example, the roller 6 may be supported in a cantilevered manner so that the roller 6 can be pivoted when loosened using a ball plunger, and fixed at a predetermined angle when tightened. However, the configuration of the above embodiment is convenient because the angle of the roller 6 can be changed without a tool.
The roller 6 may be a regular polygonal column or a column. However, if the number of corners is small, it does not rotate smoothly, and if the number of corners is too large, the tapping effect is weakened. A regular hexagonal columnar shape or a regular octagonal columnar shape is optimal.
Further, the radial groove of the grooved annular member 8 is not limited to the two or three described in each of the above embodiments, and may be four or more. From the point of not moving easily inside, 2 is preferable.
