The angle θ2 is set to a range larger than 0 degree and 40 degrees or less, for example. A ball having a spherical surface portion and a plurality of annular grooves formed on the surface of the spherical surface portion may be provided. Further, since the ball 5013 has the spheroidal surface portion as described above, the contact area between the ball 5013 and the user's skin during use is increased as compared with the balls 13A and 13B according to the first embodiment, for example. Therefore, there is an advantage that the skin can be pressed and picked up efficiently during use.

  In addition, a groove having a spherical surface portion as shown in FIGS. 14A and 14C and extending in the extension direction of the central axis J132 of the recess 6132 on the surface of the spherical surface portion (hereinafter referred to as “vertical groove”). ) 6135 may be provided with the ball 6013.

  In the embodiment, as shown in FIG. 1, the beauty device 1 including the handle body 10 and the handle 10 having the arms 12A and 12B supporting the pair of balls 13A and 13B, respectively, has been described. However, the present invention is not limited to this, and the handle 7010 is provided on the handle body 7011, the arms 7012A and 7012B, and the arms 7012A and 7012B, respectively, as in the beauty device 7 shown in FIGS. The collar portion 7019 may be included. Note that in FIGS. 15A to 15C, the same components as those in Embodiment 1 are denoted by the same reference numerals as those in FIG. Arms 7012A and 7012B rotatably support balls 7013A and 7013B, respectively. Each of the balls 7013A and 7013B has a shape including a spheroidal surface portion formed from isotropic high-density graphite (so-called egg-shaped shape), and has a flat inner surface as in FIGS. 13A to 13C. It has a hollow portion (not shown) that is circular in shape. As shown in FIGS. 15A to 15C, on the surface of the spheroidal surface of the balls 7013A and 7013B, a groove which is a so-called vertical groove extending in the extension direction of the central axis of the depression, that is, the rotation axis J7132. 7135 is formed. One or more grooves 7135 are formed along the surface of the balls 7013A and 7013B in the extension direction of the rotation axis J7132 starting from the two intersections of the surfaces of the balls 7013A and 7013B and the rotation axis J7132. The balls 7013A and 7013B are rotatable about a rotation axis J7132 that coincides with the central axis of the recessed portion while being attached to the arms 7012A and 7012B, respectively.

  The handle body 7011 has a flat box shape, and an elongated opening 7011a is provided in the center thereof. A grip portion 7011b that is gripped when the user uses the beauty device 7 is provided on the side wall of the handle body 7011. Further, two opening portions 7011d having a rectangular shape in plan view are provided on the end surface of the handle body 7011. A part of the arm 7012A and a part of the arm 7012B are arranged inside the handle body 7011. The arms 7012A and 7012B are partially inserted outside the handle body 7011 while being inserted into the openings 7011d of the handle body 7011. One end in the longitudinal direction of an elongated elliptical collar portion 7019 in a plan view is fixed to the portions of the arms 7012A and 7012B arranged outside the handle body 7011. The other end of the flange 7019 extends to a position facing the outer wall of the handle body 7011. Here, the collar portion 7019 is arranged so as to cover the opening portion 7011d of the handle body 7011 from the side. The beauty device 7 according to the present modification may include a vibrating device (not shown) that vibrates the pair of balls 7013A and 7013B, as in the beauty device 2 according to the first embodiment.

  By the way, as described above, the balls 7013A and 7013B have one or more grooves 7135 formed therein. Accordingly, when the entire beauty device 7 is moved in one direction along the surface of the skin while the pair of balls 7013A and 7013B are pressed against the skin, the pair of balls 7013A and 7013B rotate in opposite directions and the skin (skin ) Is picked up efficiently. On the other hand, when the entire beauty device 7 is moved in the opposite direction along the skin surface while the pair of balls 7013A and 7013B are pressed against the skin, the pair of balls 7013A and 7013B rotate in the opposite directions and the skin (skin) Stretch out. Then, when the entire beauty device 7 is reciprocally moved along the skin surface, the temperature of the skin (skin) rises to about 37 ° C. due to the frictional force generated between the balls 7013A and 7013B and the skin. In particular, since the balls 7013A and 7013B are so-called egg-shaped, the length of the groove 7135 is longer than the balls 13A and 13B described in the first embodiment, so that the balls 713A and 7013B are closer to the skin than the balls 13A and 13B. The generated frictional force is large. Therefore, the skin can be picked up and the skin can be stretched more efficiently.

  Here, the balls 7013A and 7013B are made of isotropic high-density graphite having a purity of 99.9%. This isotropic high-density graphite is crystallized carbon fired at 2,800 ° C. or higher and has a large heat absorption coefficient and a high heat conductivity. Then, the balls 7013A and 7013B radiate far infrared rays having a wavelength of about 10 μm when the temperature thereof reaches the same temperature as the skin (about 37 ° C.). Since the far infrared rays have substantially the same wavelength as the far infrared rays emitted from a person, when they penetrate into the inside of the skin, a molecular resonance action occurs, the temperature of the skin rises, and blood circulation of the skin is promoted.

  On the other hand, since the balls 7013A and 7013B according to the present modification are so-called egg-shaped, the groove 7135 is longer than the balls 13A and 13B described in the first embodiment and the contact with the skin is long. The area is large. Therefore, the amount of far-infrared rays penetrating the skin from the balls 7013A and 7013B is larger than that of the balls 13A and 13B described in the first embodiment, and thus there is an advantage that blood circulation of the skin is easily promoted.

  According to this configuration, since the collar portion 7019 is arranged so as to cover the opening portion 7011d of the handle body 7011 from the side, the opening portion 7011d is less likely to be visually recognized by the user, and the appearance of the beauty device 7 is aesthetic. Can be improved. In addition, since the balls 7013A and 7013B have the spheroidal surface portion, the contact area between the balls 7013A and 7013B and the user's skin during use increases as described above, so that the skin is pressed and pinched during use. The raising can be performed efficiently.

  In each embodiment, the example of the beauty device including the two balls 13A and 13B has been described, but the number of balls included in the beauty device is not limited to two and may include three or more balls. It may be.

  In the first embodiment, the example in which the contact portion that comes into contact with the skin is the balls 13A and 13B having the substantially spherical shape and the spiral groove 135 formed on the surface has been described, but the shape of the contact portion is not limited to this. For example, the groove 135 may not be formed. Further, the contact portion may be a cylindrical roller. Alternatively, protrusions may be provided on the surfaces of the balls 13A and 13B.

  In the first embodiment, grooves having different shapes may be formed on the two balls. For example, on one surface of the two balls, a spiral groove, a plurality of circular grooves, or any of the above-described vertical grooves is formed, and on the other surface, a spiral groove, a plurality of circular grooves. Of the vertical groove and a groove of a different type from the groove formed on one surface of the above-mentioned vertical groove. Further, in the first embodiment, either one of the two balls may have a spherical surface portion and the other may have a spheroidal surface portion. The two balls may have different widths or the number of grooves formed on their surfaces.

  In the second embodiment, an example has been described in which the balls 2013A and 2013B have a spherical surface portion in which no groove is formed, but the shape of the ball is not limited to this. For example, at least one of the two balls may have a spiral groove, a plurality of annular grooves, or the above-described vertical groove formed on the surface. Alternatively, at least one of the two balls may have a shape having a spheroidal surface portion.

  In the first embodiment, the example of the beauty device 1 including the vibrating devices 113A and 113B has been described, but the present invention is not limited thereto, and the vibrating devices 113A and 113B may not be included.

  Although the configuration in which the battery 111 is provided as the power supply has been described in the first embodiment, the power supply is not limited to the battery. The beauty device may be configured to include a power supply circuit including, for example, a plug connected to an outlet terminal and an AC-DC converter that converts an alternating current supplied from the outlet terminal through the plug into a direct current.

  In each of the embodiments, the example in which the balls 13A, 13B, 2013A, 2013B are formed of only isotropic graphite has been described, but the structure of the balls 13A, 13B, 2013A, 2013B is not limited to this. For example, a ball is a substantially spherical base material made of isotropic graphite, the surface of which is colored with a synthetic resin such as metal or acrylic resin or pearl, and a DLC that covers the surface of the ball body. (Diamond Like Carbon) book film. Alternatively, the ball may be one in which a metal layer is formed on the surface of the base by a metal plating treatment. According to this configuration, there is an advantage that the design of the ball, and by extension, the design of the entire beauty device is improved. Further, when the surface of the ball body is coated with a DLC book film, the burden on the skin at the time of massage is reduced, so that there is also an advantage that rough skin is suppressed. A so-called conductive DLC containing nano-order diamond and having relatively high electric conductivity may be adopted as the DLC book film. In this case, the DLC book film is formed, for example, by causing high-energy carbon ions accelerated in plasma to collide with the surface of the base material of the ball. Alternatively, the surface of the balls 13A, 13B, 2013A, 2013B may be baked and coated with a paint containing, for example, ceramic particles. Here, the particle size of the ceramic particles may be set to, for example, 50 μm to 100 μm. In this case, the surface state of the balls 13A, 13B, 2013A, 2013B can be made into a so-called matte state. Here, the matte state of the surfaces of the balls 13A and 13B may be so-called 3 minute matte, 5 minute matte, or 7 minute matte. As described above, the surfaces of the balls 13A, 13B, 2013A, and 2013B are in a matte state, and therefore, there is an advantage that the surface of the balls 13A, 13B, 2013A, and 2013B becomes smooth. The particles contained in the paint are not limited to ceramic particles, and may be particles of glass, resin or baking resin, or particles of metal such as silver.

  In each of the embodiments, the example in which the balls 13A, 13B, 2013A, 2013B are made of isotropic graphite has been described, but the present invention is not limited to this. For example, the balls 13A, 13B, 2013A, 2013B are carbon powder and resin material. It may be formed from a composite material of As this composite material, for example, a composite material containing 20 to 60% by weight of carbon powder or a composite material containing 60 to 80% by weight of carbon powder can be adopted. Here, the average particle diameter of the carbon powder contained in the composite material is about 3 μm to 10 μm. Examples of the resin material include polyurethane, polypropylene, polyamide resin, acrylic resin and other synthetic resins. In this case, the balls 13A and 13B can be manufactured using an injection molding method. The balls 13A and 13B may be formed of, for example, a C / C composite (Carbon Fiber Reinforced Carbon Composite) obtained by sintering a mixture of carbon fibers and a resin material. Alternatively, the balls 13A and 13B may be formed of anisotropic graphite.

  In each embodiment, the surface of the balls 13A, 13B, 2013A, 2013B may be blasted, and the surface thereof may be adsorbed with a deodorant having an artificial enzyme as a main component. As the deodorant, for example, a phthalocyanine-based deodorant described in the document: JP-A-56-63355 can be used. As the deodorant, a deodorant "Deolase (registered trademark)" manufactured by Orient Chemical Industry Co., Ltd. may be adopted. In addition, the surface of the ball made of isotropic graphite is a silver-based inorganic antibacterial agent composed of an inorganic ion exchanger carrying silver ions (for example, a silver-based inorganic antibacterial agent "Tobaron (registered trademark)" manufactured by Toagosei Co., Ltd.). ) May be covered with a film of dispersed material. As a material in which the silver-based inorganic antibacterial agent is dispersed, a resin material such as acrylic resin or polypropylene resin can be adopted. The proportion of the silver-based inorganic antibacterial agent contained in the coating film may be about 1%. According to this configuration, since it is possible to suppress the growth of fungi such as Escherichia coli and Salmonella on the surface of the ball, there is an advantage that the surface of the ball can be maintained in a clean state.

  In each embodiment, the example in which the contact portion is the spherical ball 13A, 13B, 2013A, 2013B has been described, but the shape of the contact portion is not limited to this. For example, the contact portion may have a polyhedral shape.
