[0009] A preferred embodiment of the present invention is described below. [1] The massage tool of the present invention comprises a guasha having an edge and at least a first surface and a second surface, and a gripping part provided on either the first surface or the second surface and extending in a direction intersecting either the first surface or the second surface. With this configuration, it is easy to apply force to the guasha while pressing it against the treatment area, so that the body can be effectively massaged. [2] The massage tool described in [1] above has a shaft extending in a direction intersecting either the first surface or the second surface on the opposite side of the gripping part from a virtual plane along the edge, and a rotor supported rotatably on the shaft, and when viewed from a direction perpendicular to the virtual plane, the rotor is located outside the edge. With this configuration, both the rotor and the gussa can be applied to the treatment area at the same time to massage, so that the body can be effectively kneaded. [3] In the massage tool described in [2] above, the rotating body, the gussa, and the gripping part may be provided in this order from front to back. With this configuration, it is easy to press both the rotating body and the gussa against the treatment area at the same time, so that the body can be effectively massaged. [4] In the massage tool described in [2] or [3] above, the Gua Sha may be provided above the gripping part, and the rotating body may be provided below the gripping part. With this configuration, it is easy to apply force to both the rotating body and the Gua Sha while pressing both of them against the treatment area, so that the body can be effectively massaged. [5] In the massage tool described in [2] to [4] above, the rotating body may be provided in a pair on the left and right, and the gussa may have left and right edges adjacent to the left and right rotating bodies. With this configuration, both the rotating body and the gussa can be applied to the treatment area simultaneously on either the left or right side of the massage tool, so that various parts of the body can be effectively massaged by changing the direction of the massage tool.

[0010] <Example> An embodiment of the present invention will be described in detail below with reference to Figs. 1 to 13. The massage device 10 in this embodiment is used mainly for massaging the body. As shown in Figs. 1 and 2, the massage device 10 includes a main body 11, a pair of rotors 12, a gussa 13, and protrusions (large protrusions 14 and small protrusions 15) for pressing the body.

[0011] In the following description, the upper side of each component when the pair of rotors 12 and the large projections 14 are simultaneously placed against the horizontal surface H will be referred to as the upper side, the lower side as the lower side, the rotor 12 side as the front side, the side opposite the rotor 12 as the rear side, and the right side and left side as viewed from the rear side to the front while standing vertically against the horizontal surface H will be referred to as the right side and the left side as the left side. In each drawing, the positive side of the X-axis is the front side, the negative side of the X-axis is the rear side, the positive side of the Y-axis is the upper side, the negative side of the Y-axis is the lower side, the positive side of the Z-axis is the right side, and the negative side of the Z-axis is the left side. The state in which the pair of rotors 12 and the large projections 14 are simultaneously placed against the horizontal surface H will be referred to as the placed state.

[0012] 1, the main body 11 includes a bifurcated portion 16, a grip portion 17, and an extension portion 18. The bifurcated portion 16 is provided at the front end of the main body 11. The grip portion 17 is provided rearward of the bifurcated portion 16. The grip portion 17 has a cylindrical shape extending in the front-rear direction.

[0013] The upper surface of the gripping portion 17 is inclined upward from the front side to the rear side in the placed state. At least a part of the gripping portion 17 is located on the horizontal plane H side of the extension line of the rotation axis R of the rotating body 12 in a side view of the massage tool 10 seen from the left and right direction. With this configuration, the skin can be pressed while alternating between pinching up and spreading without the arm holding the gripping portion 17 being significantly twisted or changed, realizing a massage tool 10 with good operability. The vertical dimension of the gripping portion 17 gradually decreases from the front side to the rear side.

[0014] Length dimension 17L of grip portion 17 is, for example, 100 mm. Length dimension 17L of grip portion 17 is the length dimension of the upper edge of grip portion 17 in a side view of massage device 10 seen from the left and right direction. Length dimension 17L of grip portion 17 is preferably set in the range of 30 mm to 200 mm. Length dimension 17L of grip portion 17 is preferably within the range of 50 mm to 170 mm. Length dimension 17L of grip portion 17 is more preferably within the range of 80 mm to 150 mm. In this case, it becomes easier for the user to grip grip portion 17, so that force can be effectively applied to the treatment area.

[0015] The lower part of the grip part 17 has a number of recesses 19. The recesses 19 are formed continuously in the front-to-rear direction. Each recess 19 is recessed in an arc shape that easily fits the user's finger. There are five recesses 19, so the grip part can be held at the front or rear, and the amount of force applied can be changed by changing the way it is held. The dimension of the grip part 17 in the left-to-right direction gradually decreases from the front to the rear, as shown in FIG. 2.

[0016] The position where the gripping part 17 is provided is not particularly limited, but the gripping part 17 extends from a substantially central position with respect to the width of the rotor 12 and the gussa 13 at the extreme ends in a side view (FIG. 1). When the gripping part 17 extends from a substantially central position, the way in which force is applied to the gussa 13 and the rotor 12 can be made uniform, and force can be applied to the treatment area more effectively. The gripping part 17 may extend from a substantially central position between the widths of the rotor 12 and the gussa 13, not limited to the width between the rotor 12 and the gussa 13, and in that case, the way in which force is applied can be made uniform at any location on the outer edge of the gussa 13, and force can be applied to the treatment area more effectively.

[0017] 3, the grip portion 17 has a shaft-shaped portion 21 and a cylindrical portion 22. The shaft-shaped portion 21 is a part of a core part 23 described later. The shaft-shaped portion 21 is inserted into a through hole 24 formed in the cylindrical portion 22. The through hole 24 penetrates the cylindrical portion 22 in the front-rear direction.

[0018] A bolt 26 is embedded in the shaft portion 21. The bolt 26 is made of a metal such as iron. The bolt 26 extends linearly rearward from the vicinity of the bifurcated portion 16. The rear end of the bolt 26 protrudes rearward from the rear end of the grip portion 17.

[0019] The cylindrical portion 22 is made of synthetic resin such as ABS resin. The surface of the cylindrical portion 22 may be covered with a covering portion. The covering portion may be made of an elastic material such as rubber or a thermoplastic elastomer. For example, a polyester (TPC) may be used as the thermoplastic elastomer.

[0020] 1, the extension portion 18 extends downward from the grip portion 17. The extension portion 18 is formed of a synthetic resin such as ABS resin or aluminum die-casting (aluminum alloy such as ADC12). The extension portion 18 has a front surface portion 27, a rear surface portion 28, and an extension surface portion 29.

[0021] The front surface portion 27 extends downward from a position forward of the grip portion 17. The front surface portion 27 is inclined rearward from the upper end to the lower end. The rear surface portion 28 extends downward from a position rearward of the grip portion 17. The rear surface portion 28 is inclined at the same angle as the front surface portion 27. The extended surface portion 29 extends from the lower end of the front surface portion 27 to the lower end of the rear surface portion 28. The extended surface portion 29 has a gently curved shape. The extended surface portion 29 is provided with a large protrusion 14 and a small protrusion 15.

[0022] As shown in Fig. 4, the extension portion 18 has a front connecting portion 32 and a rear connecting portion 33 which are connected to the grip portion 17. The front connecting portion 32 is provided at the upper end portion of the front surface 27. A hole 34 through which the shaft portion 21 of the core part 23 passes is formed in the front connecting portion 32 (see Fig. 3). The shaft portion 21 of the core part 23 passes through the hole 34 in the front connecting portion 32 and is inserted into the through hole 24 of the tubular portion 22. The front connecting portion 32 abuts against the front end surface of the grip portion 17.

[0023] The rear connecting part 33 is provided on the upper end part of the rear surface part 28. A hole 35 through which the rear end part of the bolt 26 passes is formed in the rear connecting part 33. The rear connecting part 33 abuts against the rear end surface of the grip part 17 with a ring 36 sandwiched therebetween (see FIG. 3). The rear end part of the bolt 26 is inserted into the hole 35 of the rear connecting part 33 and is fixed to the rear connecting part 33 by a flat washer 37 and a nylon nut 38. A nut cap 39 is attached to the rear surface of the rear connecting part 33. The nut cap 39 covers the nylon nut 38.

[0024] As shown in FIG. 5, the pair of rotating bodies 12 are provided at the lower end of the bifurcated portion 16. Each rotating body 12 is substantially spherical. The diameter of the rotating body 12 is 40 mm. Each rotating body 12 rotates about a rotation axis R. The opening angle α of the pair of rotation axes R is preferably in the range of 50 degrees to 110 degrees. The opening angle α of the rotation axes R is set to 65 degrees to 80 degrees. The opening angle α of the pair of rotation axes R is preferably 70 degrees.

[0025] 4 and 6, the support portion 41 that supports the rotating body 12 includes a shaft 42, a polyslider 43, a bearing 44, a bearing spacer 45, and an E-ring 46. A pair of support portions 41 are provided on the left and right sides.

[0026] The pair of shafts 42 are embedded in the bifurcated portion 16. The shafts 42 are made of metal. The shafts 42 extend downward from the bifurcated portion 16. In the placed state, the shafts 42 are inclined forward from the top to the bottom (see FIG. 1). The rotating body 12 is rotatably supported by the shafts 42.

[0027] The bearing 44 has a cylindrical shape. The bearing 44 is made of synthetic resin. The bearing 44 has an elastic protrusion 48 (see FIG. 4). The elastic protrusion 48 is caught on the inner surface of the rotating body 12. This fixes the bearing 44 to the inside of the rotating body 12.

[0028] The strength with which the pair of rotating bodies 12 pinch the treatment area can be adjusted by the angle at which the pair of rotating bodies 12 contact the treatment area, as shown in Fig. 7. Fig. 7(A) shows the case where the massage tool 10 is moved forward. In this case, the strength with which the pair of rotating bodies 12 pinch the treatment area is stronger when the massage tool 10 is in an upright position than when it is in a lying position. In this case, when the massage tool 10 is in a lying position, the pair of rotating bodies 12 push the treatment area apart. When the massage tool 10 is in a lying position, the extension portion 18 contacts the treatment area, restricting the massage tool 10 from lying down too much. This prevents the treatment effect provided by the pair of rotating bodies 12 from becoming too weak.

[0029] FIG. 7(B) shows the case where the massage tool 10 is retracted. In this case, the force with which the pair of rotating bodies 12 pinches the treatment area is stronger when the massage tool 10 is laid down than when it is upright. In this case, when the massage tool 10 is upright, the pair of rotating bodies 12 spread the treatment area to the left and right. When the massage tool 10 is laid down, the extension portion 18 comes into contact with the treatment area, and the massage tool 10 is restricted from lying down too much. This prevents the pair of rotating bodies 12 from making it difficult to achieve the treatment effect envisioned by the design.

[0030] The angle of the rotation axis R with respect to the skin when the pair of rotating bodies 12 are applied to the skin is 90 degrees, which is the boundary between pinching up and spreading. The action varies depending on the direction of movement of the massage tool 10, but assuming that the horizontal plane H in FIG. 15 is the skin, when the rotating body 12 comes into contact with the skin (the third imaginary contact point P3 in FIG. 15), if the angle formed by the rotation axis R and the skin on the side of the moving direction (the front side in the case of moving forward, and the rear side in the case of moving backward) is less than 90 degrees, the skin is pinched up, and if it is greater than 90 degrees, the skin is spread. However, since the skin is soft and the rotating body 12 sinks into the skin, even if the rotating body 12 is applied to the skin at an angle of 90 degrees before sinking, the angle at which the skin touches the skin after sinking changes, and the configuration may result in pinching up more than expected. For example, even if the rotating body 12 is applied to the skin before sinking at an angle of 85 degrees, the skin is pinched up when the rotating body 12 is sunk into the skin and moved forward.

[0031] As shown in Fig. 1, in the massage tool 10, in the placed state, the pair of rotating bodies 12, the gussa 13, and the gripping portion 17 are arranged in this order from front to rear. In the placed state, the gussa 13 is located above the pair of rotating bodies 12. The gussa 13 has a first surface portion 49, a second surface portion 51, and an edge portion 52. The edge portion 52 is formed by the outer edge of the first surface portion 49 and the outer edge of the second surface portion 51.

[0032] As shown in FIG. 1 , the first surface portion 49 faces the front side. The first surface portion 49 is continuous with the bifurcated portion 16. A front recess 70 is formed by the first surface portion 49 and the bifurcated portion 16. The second surface portion 51 faces the rear side. When viewed from the left-right direction, the upper edge of the second surface portion 51 is inclined rearward from the top to the bottom. The second surface portion 51 is continuous with the front connecting portion 32.

[0033] When viewed from the left-right direction, edge portion 52 is inclined rearward from the top to the bottom as shown in Fig. 1. In the placed state, the lower end of edge portion 52 is located higher than the upper end of rotating body 12. In the placed state, the upper end of edge portion 52 is located higher than the upper end of grip portion 17. In the placed state, the upper end of edge portion 52 is located higher than the upper end of front connecting portion 32.

[0034] When viewed from above, the edge 52 of the Guasha 13 has a gentle arc shape as shown in Fig. 2. When viewed from above, the left-right center of the edge 52 of the Guasha 13 is located forward of both left-right ends.

[0035] 1, an imaginary plane V along the edge 52 of the gussa 13 is inclined with respect to the horizontal plane H. The imaginary plane V is an imaginary plane including the edge 52 of the gussa 13. The imaginary plane V is approximately parallel to the front surface of the front surface portion 27 and the rear surface of the rear surface portion 28. The imaginary plane V includes the outer peripheral edge of the first surface portion 49 when viewed from the front, or the outer peripheral edge of the second surface portion 51 when viewed from the rear.

[0036] The grip portion 17 is provided behind the imaginary plane V. In a side view of the massage tool 10 seen from the left and right direction, the opening angle β1 between the axis 17S of the grip portion 17 and the imaginary plane V is, for example, 70 degrees. The axis 17S of the grip portion 17 is the center of the grip portion 17 in the thickness direction. The opening angle β1 is preferably set to be greater than 0 degrees and less than 180 degrees. The opening angle β1 is preferably within a range of 30 degrees or more and 150 degrees or less. It is even more preferable that the opening angle β1 is within a range of 60 degrees or more and 120 degrees or less. In this case, force can be effectively applied to the treatment area.

[0037] The shaft 42 extends toward the front side (forward) with respect to the imaginary plane V. When viewed from the left-right direction, the shaft 42 extends in an oblique direction with respect to the imaginary plane V. An opening angle β2 between the rotation axis R projected onto the XY plane and the imaginary plane V is greater than 90 degrees. The opening angle β2 is, for example, 135 degrees.

[0038] 8 shows the massage tool viewed from the front in a direction perpendicular to the imaginary plane V. The direction perpendicular to the imaginary plane V and going from the front to the rear is referred to as the first direction. Viewing the massage tool 10 in the first direction is referred to as a first direction view. When viewed in the first direction, the left and right rotating bodies 12 are located outside the edge portion 52.

[0039] The edge portion 52 has an upper edge portion 52U, a right edge portion 52R, and a left edge portion 52L. When viewed in the first direction, the upper edge portion 52U is curved. When viewed in the first direction, the left-right center portion of the upper edge portion 52U is located above both left-right ends of the upper edge portion 52U. When viewed in the first direction, the right edge portion 52R and the left edge portion 52L are adjacent to the left and right rotating bodies 12. When viewed in the first direction, the right edge portion 52R and the left edge portion 52L are curved more gently than the upper edge portion 52U. When viewed in the first direction, the up-down center portion of the right edge portion 52R is located to the right of the upper end portion and the lower end portion of the right edge portion 52R. When viewed in the first direction, the up-down center portion of the left edge portion 52L is located to the left of the upper end portion and the lower end portion of the left edge portion 52L. When viewed in the first direction, the right edge portion 52R and the right rotating body 12 form a right recessed portion 71. When viewed in the first direction, the left edge portion 52L and the left rotating body 12 form a left recess portion 72.

[0040] FIG. 9 shows the massage tool 10 viewed from the rear side perpendicular to the imaginary plane V. The direction perpendicular to the imaginary plane V and heading from the rear side to the front side is referred to as the second direction. Viewing the massage tool 10 in the second direction is referred to as the second direction view. When viewed in the second direction, the left and right rotating bodies 12 are located outside the edge portion 52. When viewed in the second direction, parts of the left and right rotating bodies 12 are hidden by the grip portion 17. When viewed in the second direction, the upper edge of the front connecting portion 32 is curved along the upper edge portion 52U.

[0041] FIG. 10 shows the massage tool 10 viewed from above in a direction parallel to the imaginary plane V. A direction parallel to the imaginary plane V and going from the top to the bottom is referred to as a third direction. Viewing the massage tool 10 in the third direction is referred to as a third direction view. In the third direction view, the pair of rotation axes R intersect in front of the imaginary plane V. In the third direction view, a right constricted portion 73 and a left constricted portion 74 are formed between the first surface portion 49 and the bifurcated portion 16. In the third direction view, the dimension in the left-right direction of the second surface portion 51 becomes smaller toward the grip portion 17. In the third direction view, the left and right edges of the second surface portion 51 are inclined at the same gradient as the left and right edges of the front connecting portion 32. In the third direction view, the right rotating body 12 protrudes rightward from the right edge portion 52R. The left rotating body 12 protrudes leftward from the left edge portion 52L.

[0042] As shown in FIG. 4, the massage tool 10 includes a core part 23. The core part 23 has a head part 56 and an axis part 21 integrally. The head part 56 has a bifurcated part 16 and a gusset 13 integrally. The axis part 21 extends rearward from the head part 56. The core part 23 is formed by integrally molding the bifurcated part 16, the gusset 13, and the axis part 21 with the shaft 42 and the bolt 26 as insert parts. The bifurcated part 16, the gusset 13, and the axis part 21 are made of synthetic resin such as ABS resin. The axis part 21 is inserted from the front connecting part 32 to the rear connecting part 33 of the extension part 18. The rear surface of the head part 56 is in contact with the front surface of the front connecting part 32. The rear end of the axis part 21 is fixed to the rear connecting part 33 of the extension part 18. This integrates the core part 23, the grip portion 17, and the extension portion 18. The integration of the grip portion 17 and the extension portion 18 increases the strength of the main body portion 11, making it easier to apply force when the large protrusions 14 and the small protrusions 15 press against the body.

[0043] Next, an example of how to use the massage device 10 will be described. By using the massage device 10, a user can effectively warm up or cool down before exercise. As shown in Figs. 11 and 12, the massage device 10 is suitable for massaging the forearm, upper arm, thigh, etc.

[0044] Examples of how to use the massage device 10 include a method using the rotating body 12 and the protrusions 14, 15, a method using only the Gua Sha 13, and a method using both the Gua Sha 13 and the rotating body 12.

[0045] Methods of using the rotating body 12 and the protrusions 14, 15 include a method of moving the massage tool 10 in a straight line as shown in Figure 12(A), a method of moving the massage tool 10 in an arc as shown in Figure 12(B), a method of using only the rotating body 12, and a method of using only the protrusions 14, 15.

[0046] The method of moving the massage tool 10 in a straight line involves moving the massage tool 10 forward in parallel with the treatment area so that the pair of rotating bodies 12, the large protrusions 14 and the small protrusions 15 are simultaneously in contact with the treatment area. With this method, the treatment area is pressed by the large protrusions 14 and the small protrusions 15 immediately after being spread apart by the pair of rotating bodies 12.

[0047] The method of moving the massage tool 10 in an arc is to move the massage tool 10 forward in an arc from a state in which only the pair of rotating bodies 12 is in contact with the body. According to this method, the treatment area is strongly pinched up by the pair of rotating bodies 12, spread apart, and pressed by the large protrusions 14 and the small protrusions 15 in turn.

[0048] In the method using only the rotating bodies 12, the pair of rotating bodies 12 is placed against the treatment area, and the massage tool 10 is moved forward and backward. At this time, the angle at which the pair of rotating bodies 12 contact the treatment area is adjusted by laying the massage tool 10 down or upright. This method is suitable for massaging the calves and lower back.

[0049] In the method using only the protrusions 14, 15, the large protrusions 14 and the small protrusions 15 are placed perpendicularly against the treatment area, and pressed against the treatment area. This method is suitable for massaging the soles of the feet and shoulders.

[0050] In the method using the Guasha 13, the gripping part 17 is gripped by placing the thumb and index finger on the front side of the gripping part 17. In the method using only the Guasha 13, the upper edge part 52U of the Guasha 13 is used. Specifically, the upper edge part 52U is placed on the treatment area, and the treatment area is rubbed or pressed with the upper edge part 52U. When only the Guasha 13 is used by gripping the gripping part 17, it is easy to apply force to the Guasha 13 while pressing the Guasha 13 against the treatment area.

[0051] In the method using both the gussa 13 and the rotating body 12, as shown in FIG. 13, the edge 52 of the gussa 13 and one rotating body 12 are simultaneously applied to the treatment site. Specifically, the right edge 52R of the gussa 13 and the right rotating body 12 are simultaneously applied to the treatment site with the right recess 71 facing the treatment site. Alternatively, the left edge 52L of the gussa 13 and the left rotating body 12 are simultaneously applied to the treatment site with the left recess 72 facing the treatment site. The force of holding the grip 17 to press the edge 52 and the rotating body 12 against the treatment site tends to act evenly on both the edge 52 and the rotating body 12. The massage tool 10 is moved back and forth while the edge 52 and the rotating body 12 are pressed against each other. This allows the treatment site to be massaged simultaneously by both the edge 52 of the gussa 13 and the rotating body 12.

[0052] The embodiment configured as described above provides the following effects. The massage tool 10 has a guassa 13 and a gripping portion 17. The guassa 13 has an edge portion 52, a first surface portion 49, and a second surface portion 51. The gripping portion 17 is provided on the second surface portion 51. The gripping portion 17 extends in a direction intersecting with the second surface portion 51. With this configuration, when the guassa 13 is used alone by gripping the gripping portion 17, it is easy to apply force to the guassa 13 while pressing it against the treatment area.

[0053] The massage tool 10 has a shaft 42 and a rotating body 12. The shaft 42 extends in a direction intersecting the first surface 49, forward of an imaginary plane V along the edge 52. The rotating body 12 is rotatably supported by the shaft 42. When the massage tool 10 is viewed from a direction perpendicular to the imaginary plane V, the rotating body 12 is located outside the edge 52. With this configuration, both the rotating body 12 and the gussa 13 can be simultaneously applied to the treatment area for massage, so that the body can be effectively massaged.

[0054] The massage device 10 is provided with the rotating body 12, the Guasha 13, and the gripping part 17 in this order from front to rear. With this configuration, it is easy to press both the rotating body 12 and the Guasha 13 against the treatment area at the same time, so that the body can be effectively massaged.

[0055] The Guasha 13 is provided above the gripping part 17, and the rotating body 12 is provided below it. With this configuration, it is easy to apply force to both the rotating body 12 and the Guasha 13 while pressing both of them against the treatment area, so that the body can be effectively massaged.

[0056] A pair of rotating bodies 12 are provided on the left and right. The Gua 13 has a left edge 52L and a right edge 52R adjacent to the left and right rotating bodies 12. With this configuration, both the rotating body 12 and the Gua 13 can be simultaneously applied to the treatment area on either the left or right side of the massage tool 10, so that various parts of the body can be effectively massaged by changing the direction of the massage tool 10.

[0057] <Other Examples> The present invention is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments are also included within the technical scope of the present invention. (1) In the above embodiment, the massage device 10 includes a pair of rotating bodies 12. However, the massage device is not limited to this, and may include only one rotating body, or may include three or more rotating bodies. (2) In the above embodiment, the massage tool 10 has the protrusions 14, 15 for pressing against the body. However, the present invention is not limited to this, and the massage tool does not have to have protrusions for pressing against the body. (3) In the above embodiment, an example of use of the massage device 10 has been described. However, the massage device 10 may be used for various purposes. For example, the massage device 10 may be used for beauty purposes. (4) In the above embodiment, the grip portion 17 has a shape that is long in the front-rear direction. However, the grip portion is not limited to this, and may have a flat shape or a block shape that is wide in the up-down or left-right direction. (5) In the above embodiment, the main body 11 has the extension 18. However, the present invention is not limited to this, and the main body does not have to have the extension. In addition, only the front connecting portion may be left, and the gussa and the gripping portion may be connected via the front connecting portion. (6) In the above embodiment, the guassa may have a third surface in addition to the first and second surfaces. In that case, the guassa will be triangular and have multiple edges, but by providing a gripping part that intersects with one of the surfaces as in the embodiment, it is possible to easily apply force when the guassa is pressed against the treatment area. The same effect can be obtained even if the number of surfaces is increased. (7) Regarding the shape of the rotating body in the above embodiment, the aforementioned "approximately spherical" includes a perfect sphere and a shape that is a distortion of a perfect sphere to an extent that is generally recognized as a sphere, such as a spheroid or teardrop shape. The rotating body may have a surface composed of smooth curved surfaces, and may be a polyhedron having a surface composed of a large number of triangles, squares, etc. When the rotating body is a polyhedron, the surface of the rotating body can be prevented from slipping against the skin, compared to a rotating body having a surface composed of smooth curved surfaces, and a better beauty effect can be expected. (8) The shape of the main body in the above embodiment is not limited to a long shape, and may be substantially spherical. In this case, the gripping portion refers to the entire portion that can be gripped, and at least a part of the gripping portion may be located closer to the ground surface than the rotation axis angle (imaginary line) of the rotor in a side view when the rotor and the protrusion are grounded at three points. (9) When the massage device is viewed from a direction perpendicular to the first surface or the second surface on which the shaft is provided, even if the rotating body is located outside the edge, both the rotating body and the guassa can be easily pressed against the treatment area at the same time, allowing the body to be effectively massaged. (10) For example, the entire surfaces of the first and second surfaces may be formed with wave-like irregularities, or the surfaces of the first and second surfaces may be curved. In this case, a plane including any three points on the edge may be defined as imaginary plane V. The same effect as in the above embodiment can be obtained even when the gripping portion and the shaft extend in a direction intersecting with the imaginary plane defined in this way.
