In the following embodiments, the same components are denoted by the same reference numerals, and redundant description is omitted. Moreover, in each drawing, a part of component is abbreviate | omitted suitably for convenience of explanation.

The background that led to the first to fifth embodiments will be described.

¡There are products that use the far infrared effect by forming the roller with carbon. Far-infrared rays promote blood circulation near the body surface, warming the whole body over time. Patent Document 1 discloses such a product.

多く Many users of beauty equipment are women. Naturally, women who are conscious of beauty also take care of makeup that makes them stand out. After cleansing the face, apply lotion, milky lotion or cream, sunscreen depending on the season, cover the pores on the makeup base, and apply the foundation using a control color. Acne and stains are concealed with a concealer, finished with powder, and then lipstick. There are so many ingredients on a woman's face.

In the massage device of Patent Document 1, there is a gap between the through hole and the fastening member. In order to obtain a massage effect or a facial effect, the roller is rolled on the skin of the face a considerable number of times, so that the makeup components easily transfer to the roller, and a part of it enters into the gap. The same applies to sweat and oil on the film. If this is repeated every day, there is a risk that the roller will not rotate well due to unwanted material adhering to the roller shaft. There is room for improvement in fully exhibiting the far-infrared effect of a roller formed of carbon.

The first to fifth embodiments have been made in view of this problem, and one of the exemplary purposes of an aspect thereof is to provide a cosmetic device that can sufficiently exhibit the far-infrared effect. .

[First Embodiment]
1 is a perspective view of a cosmetic device 1 according to the first embodiment, FIG. 2 is a top view of the cosmetic device 1, FIG. 3 is a front view showing a usage state of the cosmetic device 1, and FIG. FIG.

The cosmetic device 1 has a pair of rollers 10 and a handle 20. Each roller 10 is a rotating body formed in a spherical shape, and is rotatably supported by a bifurcated portion 201 provided at one end of the handle 20. The user of the beauty device 1 holds the handle 20 and presses the roller 10 against the skin 30 such as the face and arms. At that time, the user moves the handle along the skin 30. When the pair of rollers 10 rotate, the skin 30 is picked up or pushed between the rollers 10. More specifically, when the handle is moved in the direction of arrow R while pressing the roller 10 against the skin 30 in the state shown in FIG. 3, the skin 30 is picked up between the two rollers 10. When the handle is moved in the direction of arrow L, the skin 30 is pushed and spread by the two rollers 10. Conversely, holding the handle 20 so as to stand perpendicular to the surface of the skin 30 and moving it in the direction of the arrow R, the skin 30 is pushed and spread, and if it is moved in the direction of the arrow L, the skin 30 is picked up. In this way, the beauty device 1 can be used to massage the skin 30 by picking up or pushing it out.

The skin 30 is massaged by the roller 10 to promote circulation of blood flow and lymph. Further, the skin 30 is lifted up and stretched by being picked up by the roller 10 or spread. As described above, various cosmetic effects can be obtained by the cosmetic device 1.

The roller 10 is formed in a spherical shape having a large number of triangular surfaces 101 on the surface. However, the roller 10 may have an ellipsoidal shape, a cylindrical shape, or the like other than a spherical shape. Further, the surface 101 may be a polygon other than a triangle, a circle, or the like.

The roller 10 is a carbon molded body formed of a material containing carbon. The raw material is obtained by adding a binder to graphite carbon powder. The raw material is pressed into a spherical shape and fired at a high temperature for a long time, whereby the roller 10 can be formed. By firing, the carbon powders are bonded to each other to be crystallized, that is, graphitized and shaped carbonized. Further, since the binder volatilizes during the temperature rise during firing, in the prototype of the present applicant, about 99% or more of the roller 10 can be made of carbon.

Due to the characteristics of carbon, the roller 10 has high thermal conductivity and emissivity. For this reason, the roller 10 is warmed to the same temperature as the skin 30 in a short time from the start of use of the cosmetic device 1, and the amount of radiation of far infrared rays increases. When far-infrared rays are radiated from the roller 10 to the skin 30, blood flow in the skin 30 and circulation of lymph are promoted. As a result, a beauty effect is obtained.

In the final process of making the roller 10, a diamond-like carbon (DLC) DLC film is adhered to the surface. The thickness of the DLC film is 2 to 4 μm. The DLC film is formed as carbon having a crystal structure by plasma CVD or PVD, and has good adhesion to the roller 10. The DLC film is hard and suitable for protection from damage to the roller 10.

The roller 10 is supported by the handle 20 so as to be rotatable about the rotation axis X. The maximum diameter L in the direction orthogonal to the rotation axis X of the roller 10 is 40 mm. The maximum diameter L of the roller 10 is preferably 15 to 60 mm, more preferably 32 to 55 mm, and particularly preferably 38 to 45 mm in the experimental results by the present applicant in order to use the cosmetic device 1 on the face and arms. If the maximum diameter L of the roller 10 is smaller than 15 mm, the contact area between the roller 10 and the skin 30 becomes small, and there may be a case where a sufficient effect by the cosmetic device 1 cannot be obtained. On the other hand, if the maximum diameter L of the roller 10 is larger than 60 mm, it may be difficult to press the roller 10 to rotate depending on the body part.

The distance D between the pair of rollers 10 is 11.5 mm. The distance D between the rollers 10 is preferably 8 to 25 mm, more preferably 9 to 15 mm, and particularly preferably 10 to 13 mm in order to appropriately pick up or spread the skin 30. If the distance D is smaller than 8 mm, the force to pick up the skin 30 may become too strong or difficult to spread. On the other hand, if the distance D is greater than 25 mm, it may be difficult to pick up the skin 30.

Each of the pair of rollers 10 is attached to a support shaft (described later) provided on one end side of the handle 20. The two support shafts are provided such that the distance between the two support shafts increases as the distance from the handle 20 increases. The opening angle α of the rotation axis X of the roller 10 is 75 degrees. This angle is preferably 50 to 110 degrees, more preferably 50 to 90 degrees, and particularly preferably 65 to 80 degrees so that the roller 10 can easily pick up or spread the skin 30. When the opening angle α is smaller than 50 degrees, the force to pick up the skin 30 may become too strong or difficult to spread. On the other hand, if the opening angle α is larger than 110 degrees, it may be difficult to pick up the skin 30.

The roller 10 is provided such that the rotation axis X is inclined with respect to the center line Y of the handle 20. The center line Y of the handle 20 is a line parallel to a line that bisects the angle between the outer peripheral tangents Z of the thickest part of the handle 20 in a front view of the cosmetic device 1. The inclination angle β between the rotation axis X of the roller 10 and the center line Y of the handle 20 is 95 degrees. The inclination angle β is set to an angle at which the user easily holds the handle 20 and presses the roller 10 against the skin 30 to rotate.

FIG. 5 is a partial cross-sectional view taken along line AA in FIG. The handle 20 includes a base body 202, an upper cover body 204, and a lower cover body 206. These are formed of a resin material.

The cap 240 is formed in a cylindrical shape from a resin material, and seals between the base body 202 and the upper cover body 204 and between the base body 202 and the lower cover body 206. Further, when one opening fits into the flange portion 505 of the support shaft 50, rattling of the support shaft 50 is reduced.

The support shaft 50 has a seal ring 504 attached to a recess 503 formed so as to be positioned inside the shaft hole 222 of the base body 202. The seal ring 504 seals between the outer peripheral surface of the support shaft 50 and the inner peripheral surface of the shaft hole 222. The handle 20 is double-sealed by a cap 240 and a seal ring 504.

The support shaft 50 has a bearing 60 attached to a support portion 506 protruding from the handle 20. A retaining ring 507 is provided at the tip of the support portion 506. The retaining ring 507 is fitted into a groove formed in the support shaft 50. The bearing 60 cannot be detached from the support shaft 50 by being caught by the retaining ring 507. When the bearing 60 is attached to the support shaft 50, the inner peripheral surface is in a state of being rotatable while being in sliding contact with the outer peripheral surface of the support shaft 50.

FIG. 9 is a perspective view of the bearing 60 in the first embodiment. The bearing 60 is formed in a cylindrical shape from a resin material. The bearing 60 includes a locking claw 601 and a support piece 602. The locking claw 601 is formed so as to protrude outward from the bearing 60 from one end of the support piece 602. The end of the support piece 602 opposite to the locking claw 601 is connected to the side wall of the bearing 60. The support piece 602 is elastically deformed so as to bend when the locking claw 601 is pushed toward the inside of the bearing 60.

As shown in FIG. 6, the support shaft 50 is inserted into the shaft holder 70 with the bearing 60 attached. The shaft holder 70 is fixed to the recess 110. In the recess 110, an R portion 111 is formed at the periphery of the back end portion opposite to the opening side. By forming the R portion 111 and forming the back end portion as a curved surface, it is possible to prevent stress from concentrating on the periphery of the back end portion of the recess 110 and to reduce the occurrence of cracks from the recess 110.

The shaft holder 70 is formed in a cylindrical shape from a resin material, and has a concave portion 701, a locking portion 702, and a pressing portion 704. The recess 701 is formed so as to be recessed from the inner peripheral surface of the shaft holder 70 toward the outer peripheral surface. The locking portion 702 protrudes inward from the opening-side end portion of the recess 110. A stepped portion 703 is formed by the inner diameter difference between the recess 701 and the locking portion 702. The stepped portion 703 locks the locking claw 601 of the bearing 60 inserted into the shaft holder 70. The pressing portion 704 protrudes inward from the end opposite to the locking portion 702. The inner diameters of the locking part 702 and the pressing part 704 are equal to the outer diameter of the bearing 60. For this reason, in a state where the bearing 60 is inserted into the shaft holder 70, the inner peripheral surfaces of the locking portion 702 and the pressing portion 704 are in contact with the outer peripheral surface of the bearing 60. As the roller 10 is supported by the shaft holder 70 at different positions in the rotation axis direction, rattling with respect to the rotation axis direction is reduced.

When the support shaft 50 and the bearing 60 are inserted into the shaft holder 70, the locking claw 601 of the bearing 60 is displaced inside the bearing 60 and passes through the locking portion 702 of the shaft holder 70. In addition, when the locking claw 601 passes through the locking portion 702 of the shaft holder 70 and enters the recess 701, the locking claw 601 returns to the original position protruding outside the bearing 60. In this state, the locking claw 601 of the bearing 60 is locked to the stepped portion 703, and the support shaft 50 and the bearing 60 can not be removed from the shaft holder 70.

When the support shaft 50 and the bearing 60 are inserted into the shaft holder 70, the roller 10 is rotatably supported by the handle 20. When the roller 10 is pressed against the skin and rotates, the shaft holder 70 fixed to the recess 110 also rotates together with the roller 10. Further, the bearing 60 is provided so that its inner peripheral surface is slidably in contact with the outer peripheral surface of the support shaft 50 and rotates with respect to the support shaft 50 together with the roller 10.

Further, a coil spring 80 is provided as an impact absorbing portion between the shaft holder 70 of the roller 10 and the cap 240 of the handle 20. The coil spring 80 presses the shaft holder 70 in the direction opposite to the handle 20. When the roller 10 hits something or falls to the floor, the coil spring 80 compresses and absorbs the impact applied to the roller 10 to reduce damage to the roller 10. The coil spring 80 may be provided between the bearing 60 and the cap 240 of the handle 20. The impact absorbing portion may be a rubber other than the coil spring 80, a polystyrene foam, or a urethane sheet as long as it is an elastic member that can be elastically deformed to absorb the impact.

As described above, in the cosmetic device 1 according to the first embodiment, the roller 10 is supported by the support shaft 50 inserted into the shaft holder 70 of the recess 110. The roller 10 is not formed with a through-hole, and the attachment of skin or the like does not enter and the rotation is not hindered. For this reason, the roller 10 can continue to rotate stably, and the far-infrared effect can be exhibited stably and sufficiently over a long period of time. Further, by providing the shaft holder 70 in the recess 110 of the roller 10, the occurrence of chipping, scraping, and cracking in the roller 10 can be reduced compared with the case where the bearing 61 is directly held in the recess 110, and the beauty can be maintained for a longer period. The device 1 can be used. According to the beauty machine 1, when the two rollers 10 are pressed against the skin and rotated, the skin is picked up or spread.

When the roller 11 is pressed against the skin and rotates, the bearing 61 together with the shaft holder 71 also rotates with respect to the support shaft 51.

As described above, according to the cosmetic device 5 in the fourth embodiment, the skirt portion 219 of the handle 21 covers the opening peripheral edge portion 114 of the recess 113 of the roller 11, so that the roller 11 is chipped or cracked, and the inside. Intrusion of foreign matter is reduced. Thereby, since the roller 11 has a long life and can continue to rotate stably, the beauty effect by far-infrared rays and picking and spreading can be exhibited over a long period of time. An impact absorbing portion may be provided between the bearing 61 and the handle 21. The damage received by the roller 11 at the time of dropping is reduced, and the roller 11 can be used for a longer period.

[Sixth Embodiment]
FIG. 21 is a perspective view of the cosmetic device 1 according to the sixth embodiment, FIG. 22 is a top view of the cosmetic device 1, FIG. 23 is a front view showing the usage state of the cosmetic device 1, and FIG. FIG.

The cosmetic device 1 has a pair of rollers 10 and a handle 20. Each roller 10 is a rotating body having a spherical surface with a black surface, and is rotatably supported by a bifurcated portion 201 provided at one end of the handle 20. The user of the beauty device 1 holds the handle 20 and rolls it by applying the roller 10 to the face or arm. The skin is picked up or spread between the rollers 10 to promote blood flow and lymph circulation in the contact portion. In addition, the skin is lifted up and tensioned. As described above, various cosmetic effects can be obtained by the cosmetic device 1.

The roller 10 is formed in a spherical shape having a large number of triangular surfaces 101 on the surface. However, the roller 10 may have an ellipsoidal shape, a cylindrical shape, or the like other than a spherical shape. Further, the surface 101 may be a polygon other than a triangle, a circle, or the like. Further, the entire surface can be smooth without providing the surface 101.

The roller 10 is a carbon molded body formed of a material containing carbon. The raw material is obtained by adding a binder to graphite carbon powder. The raw material is pressed into a spherical shape and fired at a high temperature for a long time, whereby the roller 10 can be formed. By firing, the carbon powders are bonded to each other to be crystallized, that is, graphitized and shaped carbonized.

Due to the characteristics of carbon, the roller 10 has high thermal conductivity and emissivity. For this reason, the roller 10 is warmed to the same temperature as the skin 30 in a short time from the start of use of the cosmetic device 1, and the amount of radiation of far infrared rays increases. When far-infrared rays are radiated from the roller 10 to the skin 30, blood flow in the skin 30 and circulation of lymph are promoted.

Each of the pair of rollers 10 is attached to a support shaft (described later) provided on one end side of the handle 20. The two support shafts are provided such that the distance between the rotation axis X of the roller 10 increases as the distance from the handle 20 increases. Accordingly, as shown in FIG. 23, when the roller 10 is applied to the skin 30 and moved in the direction of the arrow R, the skin 30 is picked up so as to be caught between the two rollers 10. On the other hand, when it is moved in the direction of the arrow L, the skin 30 is pushed and spread by the two rollers 10. By providing the opening angle α on the rotation axis X of the two rollers 10, two usages of picking up and spreading the skin 30 are possible.

The opening angle α is 75 degrees. The opening angle α is preferably 50 to 110 degrees, more preferably 50 to 90 degrees, and particularly preferably 65 to 80 degrees so that the roller 10 can easily pick or spread the skin 30. When the opening angle α is smaller than 50 degrees, the force to pick up the skin 30 may become too strong or difficult to spread. On the other hand, if the opening angle α is larger than 110 degrees, it may be difficult to pick up the skin 30.

FIG. 28 is a view of the holding member 230 according to the sixth embodiment, as viewed from the surface on the base body 202 side in a state of being attached to the base body 202. The holding member 230 is made of a resin material, and has a holding portion 231 and a screw hole 232. The holding member 230 is fixed to the base body 202 with a screw inserted into the fixing hole 223 of the base body 202 through the screw hole 232. The holding portion 231 is formed in a semi-cylindrical shape, and holds the base end portion side of the support shaft 50 in a state where the holding member 230 is fixed to the base body 202.

As shown in FIG. 26, the support shaft 50 is formed with a held portion 501 having a smaller diameter than other portions on the base end side held by the handle 20. Further, a retaining portion 502 having a diameter larger than that of the held portion 501 is formed. The support shaft 50 is inserted into the shaft hole 222 of the base body 202 on the base end side, and the held portion 501 is held by the holding portion 231 of the holding member 230. In this state, the retaining portion 502 is locked to the holding member 230 so that the support shaft 50 cannot be detached from the handle 20.

A cap 240 is put on the end of the handle 20 on the roller 10 side. The cap 240 is formed in a cylindrical shape from a resin material, and seals between the base body 202 and the upper cover body 204 and between the base body 202 and the lower cover body 206. Moreover, one opening fits in the flange part 505 of the support shaft 50, and the shakiness of the support shaft 50 is reduced.

The support shaft 50 has a seal ring 504 attached to a recess 503 formed so as to be positioned inside the shaft hole 222 of the base body 202. The seal ring 504 seals between the outer peripheral surface of the support shaft 50 and the inner peripheral surface of the shaft hole 222. The handle 20 is double-sealed on the roller 10 side by a cap 240 and a seal ring 504.

The support shaft 50 has a bearing 60 attached to a support portion 506 protruding from the handle 20. A retaining ring 507 is provided at the tip of the support portion 506. The retaining ring 507 fits into a groove formed at the tip of the support shaft 50 and prevents the bearing 60 from coming off the support shaft 50. When the bearing 60 is attached to the support shaft 50, the bearing 60 is in a rotatable state while the inner peripheral surface is in contact with the outer peripheral surface of the support shaft 50.

FIG. 29 is a perspective view of a bearing 60 in the sixth embodiment. The bearing 60 is formed in a cylindrical shape from a resin material. The bearing 60 includes a locking claw 601 and a support piece 602. The locking claw 601 is formed so as to protrude outward from the bearing 60 from one end of the support piece 602. The end of the support piece 602 opposite to the locking claw 601 is connected to the side wall of the bearing 60. The support piece 602 is elastically deformed so as to bend when the locking claw 601 is pushed toward the inside of the bearing 60.

As shown in FIG. 26, the support shaft 50 is inserted into a bearing hole (dent) 110 formed in the roller 10 with the bearing 60 attached. In the bearing hole 110, an R portion 111 is formed on the periphery of the back end portion opposite to the opening side. By forming the R part 111 and making the back end part into a curved surface, it is possible to prevent stress from concentrating on the periphery of the back end part of the bearing hole 110 and to suppress the occurrence of cracks. On the inner peripheral surface of the bearing hole 110, a concave portion 112 into which the locking claw 601 of the bearing 60 is fitted is formed. When the locking claw 601 is inserted into the recess 112, the locking claw 601 is locked to a step 113 formed on the handle 20 side of the recess 112. As a result, the support shaft 50 and the bearing 60 cannot be removed from the roller 10.

When the support shaft 50 and the bearing 60 are inserted into the bearing hole 110, the roller 10 is rotatably supported by the handle 20. The roller 10 rotates together with the bearing 60 when it is rolled against the skin.

Further, a coil spring 80 is provided as an impact absorbing portion between the roller 10 and the cap 240. The coil spring 80 presses the roller 10 in the direction opposite to the handle 20. When the roller 10 hits something or falls to the floor, the coil spring 80 compresses and absorbs an impact applied to the roller 10 to reduce damage to the roller 10. The coil spring 80 may be provided between the bearing 60 and the cap 240 of the handle 20. The impact absorbing portion may be a rubber other than the coil spring 80, a polystyrene foam, or a urethane sheet as long as it is an elastic member that can be elastically deformed to absorb the impact.

The sixth embodiment has been described above. The roller 10 of the cosmetic device 1 is a carbon molded body, and the blood flow of the skin and the circulation of lymph are promoted by the effect of far infrared rays. Further, by picking up the skin with the two rollers 10, in addition to the far-infrared effect, a further blood flow promoting effect, a lift-up effect, and the like can be obtained.

30 (a) and 30 (b) are schematic diagrams for explaining the function and effect of the cosmetic device 1. FIG. 30A shows a state before the skin 30 is picked up, and FIG. 30B shows a state where the skin 30 is picked up so that the skin 30 is caught between the two rollers 10. According to the cosmetic device 1, as shown in FIG. 30B, the skin 30 is picked up so as to be caught between the two rollers 10, and the picked up skin 30 comes into contact with the roller 10. That is, picking up the skin 30 increases the contact area between the skin 30 and the two rollers 10. As a result, more heat is transferred from the skin 30 earlier to the two rollers 10, and the two rollers 10 are warmed to the same temperature as the skin 30 in a shorter time, or closer to the skin 30, that is, more The two rollers 10 are heated to a high temperature, and the amount of far infrared rays emitted increases. By the way, the wavelength of water molecules in the body is approximately equal to the wavelength of far infrared rays emitted from carbon, and when the far infrared rays reach the water molecules in the body, the water molecules vibrate by resonance and collide with other water molecules. Heat is generated by the collision of water molecules, and circulation of blood flow and lymph is promoted. When the amount of far-infrared rays emitted from the two rollers 10 increases, the vibration of water molecules in the body becomes larger, and therefore more heat is generated by the collision of water molecules, and blood flow and lymph circulation are further promoted. .

Further, according to the beauty device 1, the skin 30 is picked up so as to be caught between the two rollers 10, whereby the distance between the two rollers 10 and the deep skin portion is shortened. For example, the distance between the two rollers 10 and the portion of the dermis layer 30a of the skin 30 (for example, the deep skin portion S) is shortened by picking up the skin 30 as shown in FIGS. 30 (a) and 30 (b). . Thus, far-infrared rays may not reach the dermis layer 30a when the skin 30 is not picked up. By picking up the skin 30, far-infrared rays can be delivered to the dermis layer 30a more reliably, Thirty deeper water molecules can resonate. Furthermore, the vibration of water molecules becomes larger in the portion where both the far infrared rays radiated from the two rollers 10 reach. That is, according to the cosmetic device 1, it is possible to cause a greater vibration of water molecules in a deeper part of the skin 30, and as a result, the blood flow of the skin and the circulation of lymph are further promoted.

The configuration shown in FIG. 31 may be used. In the cosmetic device 1 </ b> A shown in FIG. 31, a first protrusion 605 and a second protrusion 606 are formed on the bearing 60. These protrusions protrude outward from the outer peripheral surface of the bearing 60 at different positions in the rotation axis direction. Further, the bearing hole 110 is formed with a protrusion 121 protruding inward. The first protrusion 605 is locked to the step 113 formed by the protrusion 121 in a state where the bearing 60 is inserted into the bearing hole 110. The first protrusion 605 and the second protrusion 606 are in contact with the inner peripheral surface of the bearing hole 110 at different positions in the rotation axis direction, respectively, to reduce the backlash of the roller 10 in the rotation axis direction.

FIG. 35 is a perspective view of the cosmetic device 5 according to the ninth embodiment. 36 (a) is a top view of the cosmetic device 5, FIG. 36 (b) is a front view, and FIG. 36 (c) is a bottom view.

The beauty machine 5 has a pair of rollers 11 and a handle 21. Each roller 11 is a carbon molded body formed of the same material and method as the roller 10 in the sixth embodiment, and is rotatably supported by the handle 21. A plurality of grooves 15 extending along the rotation axis are formed on the surface of the roller 11. In other words, the roller 11 has a plurality of grooves 15 extending radially from one end side to the other end side of the roller 11 in the rotation axis direction. The handle 21 includes a main body 211 held by a user and a forked portion 213 branched from one end of the main body 211. The bifurcated portion 213 is provided with a support shaft that rotatably supports the roller 11. The diameter of the roller 11, the interval, the opening angle of the rotating shaft, and the inclination angle of the rotating shaft with respect to the center line Y of the handle 21 are the same as in the sixth embodiment.

FIG. 37 is a cross-sectional view taken along the line CC of FIG. The handle 21 has an upper cover body 215, a handle core 217, and a lower cover body 218. A method for manufacturing the handle 21 will be described. First, the upper cover body 215 is molded with resin. The upper cover body 215 is provided with a cross boss 216 for positioning the handle core 217. Next, the handle core 217 is formed integrally with the upper cover body 215 by two-color molding. Further, the lower cover body 218 is formed integrally with the upper cover body 215, the handle core 217, and the support shaft 51 attached to the mold. When the handle 21 is relatively thick, if the handle core 217 is made thicker according to the thickness of the handle 21 and the upper cover body 215 and the handle core 217 are made thinner, the upper cover body 215 and the handle core 217 exposed to the outside may have sink marks. It is possible to suppress the occurrence, and it is possible to realize the handle 21 having a good aesthetic appearance. Moreover, the assembly error of the support shaft 51 can be reduced by fixing the support shaft 51 to the handle 21 by insert molding. Thereby, individual variation of the beauty device 5 can be suppressed, and functions such as picking up and spreading by the two rollers 11 can be secured.

FIG. 38 is a partial cross-sectional view taken along the line DD in FIG. The support shaft 51 is fixed to the lower cover body 218 of the handle 21. The support shaft 51 has a large-diameter portion 513 having a larger diameter than other portions. A D-cut surface 514 is formed in the large diameter portion 513. The support shaft 51 is fixed to the handle 21 by engaging the large diameter portion 513 including the D-cut surface 514 with the lower cover body 218. The lower cover body 218 has a skirt portion 219 that covers the opening peripheral edge portion 114 of the bearing hole (dent) 118 formed in the roller 11. Since it is covered with the skirt portion 219 and is not exposed to the outside, the opening peripheral edge portion 114 is less likely to be chipped or cracked. In addition, entry of foreign matter into the roller 11 is reduced. The skirt portion 219 may be formed on the upper cover body 215 or the handle core 217.

The bearing hole 118 of the roller 11 is a hole recessed in a cylindrical shape, and the support shaft 51 is inserted therein. The bearing hole 118 has a tapered surface 117 which is inclined at a rear end opposite to the opening side so that a diameter in a cross section perpendicular to the axial direction of the support shaft 51 gradually decreases from the side surface 115 toward the bottom surface 116. Has been. Stress concentration at the back end is suppressed, and the generation of cracks from the bearing hole 118 is reduced. Similarly to the sixth embodiment, the back end of the bearing hole 118 may be a curved surface. A concave portion 119 into which a locking claw 607 of a bearing 61 (described later) is fitted is formed on the inner peripheral surface of the bearing hole 118. The locking claw 607 is locked to the step 113 formed by the recess 119 in the state of entering the recess 119.

A bearing 61 is attached to the support shaft 51. The bearing 61 is a sliding bearing having a locking claw 607 protruding outward. A retaining ring 508 is attached to the tip of the support shaft 51 with the bearing 61 inserted. When the bearing 61 is inserted into the bearing hole 118 together with the support shaft 51, the locking claw 607 fits into the recess 119 of the bearing hole 118, and the flange portion 608 of the bearing 61 fits into the opening of the bearing hole 118. When the roller 11 is pressed against the skin and rotates, the bearing 61 and the support shaft 51 rotate together with the roller 11.

The bifurcated portion 213 of the handle 21 has a shape that expands in a trumpet shape toward the roller 11, and when viewed in a cross section as shown in FIG. Formed as follows. As a result, the bifurcated portion 213 and thus the handle 21 and the roller 11 have a clean appearance as if they are an integral member.

FIG. 39 is a cross-sectional view taken along line EE in FIG. FIG. 39 is a cross-sectional view of a plane including the rotation axis of the roller 11. In FIG. 39, the plane P indicates a plane parallel to the end surface on the roller 11 side of the bifurcated portion 213 of the handle 21. As is clear from FIG. 39, the roller 11 and the bifurcated portion 213 are such that the rotation axis X of the roller 11 and the normal line N of the plane P are non-parallel and close to the other roller 11 with respect to the rotation axis X. The portion of the roller 11 on the side is formed such that the exposed portion that is not covered by the bifurcated portion 213 increases. As a result, the bifurcated portion 213 does not interfere with the picked up skin, so that the user can use the skin without discomfort.

FIG. 40 is a partial cross-sectional view of the roller 11. In FIG. 40, the fragmentary sectional view by the plane containing the equator of the roller 11 is shown. The equator of the roller 11 is a great circle formed by the intersection of the plane perpendicular to the rotation axis of the roller 11 and the outer peripheral surface of the roller 11. When the maximum diameter L in the direction perpendicular to the rotation axis X of each roller 11, the distance D between the two rollers 11, and the opening angle α of the rotation shafts of the two rollers 11 are in the range described above in the sixth embodiment. In order to appropriately pick up or spread the skin 30 or to increase the effect of far infrared rays by increasing the contact area with the skin, the dimensions relating to the groove 15 are preferably as follows.
Groove width W: 1.1 to 1.4 mm
Groove interval G: 0.5 to 0.7 mm
Groove depth H: 0.4 to 0.5 mm
Number of grooves: 50-60

Further, regarding the relationship between the groove width W and the groove depth H, the ratio of the groove depth H to the groove width W is preferably 0.36. If the ratio of the groove depth H to the groove width W is larger than 2.0, that is, if the groove 15 is too deep, the skin does not contact the bottom surface of the groove 15 and the presence of the groove 15 makes the contact area smaller.

The ninth embodiment has been described above. According to the cosmetic device 5 in the ninth embodiment, the same effects as those of the cosmetic device 1 in the first embodiment can be obtained. Moreover, according to the cosmetic device 5, since the grip force of the roller 11 is improved by the groove 15 formed on the surface of the roller 11, the skin can be easily picked up and spread with a lighter force. In addition, since the skirt portion 219 of the handle 21 covers the opening peripheral edge portion 114 of the bearing hole 118 of the roller 11, chipping and cracking of the roller 11 and entry of foreign matter into the inside are reduced. Thereby, since the roller 11 has a long life and can continue to rotate stably, the beauty effect by far-infrared rays and picking and spreading can be exhibited over a long period of time. An impact absorbing portion may be provided between the bearing 61 and the handle 21. The damage received by the roller 11 at the time of dropping is reduced, and the roller 11 can be used for a longer period. In addition, although the structure which formed the groove | channel 15 extended radially as a recessed part on the surface of the roller 11 was demonstrated, a recessed part is not restricted to this. For example, a lattice-shaped groove or a plurality of dimples similar to those of a golf ball may be formed as a recess on the surface of the roller 11. Also in this case, the effect of picking up and spreading the skin is improved as in the case of the groove 15.

Further, according to the cosmetic device 5, since the groove 15 is formed on the roller 11, the surface area of the roller 11 is larger than when the groove 15 is not formed on the roller 11. The contact area becomes larger. As a result, more heat is transferred from the skin 30 earlier to the two rollers 10, and the two rollers 10 are warmed to the same temperature as the skin 30 in a shorter time, or closer to the skin 30, that is, higher. The two rollers 10 are warmed to the temperature, and as a result, the blood flow of the skin and the circulation of lymph are further promoted.

Further, according to the cosmetic device 5, since the groove 15 is formed in the roller 11, when the roller 11 is rotating, it can be seen at a glance that the roller 11 is rotating. As a result, for example, it is easy to check the visual rotation as one of quality tests before product shipment.

Note that the handle 21 may have a configuration different from that of the above-described embodiment as long as the handle 21 having a good aesthetic appearance without sink marks can be realized. For example, the handle 21 may be composed of two members, in particular, two members that are thin enough to prevent sink marks. In this case, the manufacturing cost of the handle 21 can be reduced. For example, the handle 21 may be formed by blow molding. In this case, since only one mold is necessary for molding the handle 21, the manufacturing cost of the handle 21 can be reduced.

The dimension of each part of the suitable Example of the cosmetics device 5 in 9th Embodiment is shown.

The present inventor conducted a test for confirming the effect of the beauty device 5 in the ninth embodiment. Specifically, the comparison is made in the same manner as the cosmetic device 5 of the first example in the ninth embodiment except that the groove 15 is not formed on the roller 11 and the cosmetic device 5 of the first example. A test for confirming the difference in bodily sensation was performed using the cosmetic device according to the example.

The test was conducted on 10 men and women in their 20s to 40s (5 men and 5 women). The subjects were allowed to rest for 20 to 30 minutes before each test, and the cosmetic device 5 was used on the right cheek and the comparative cosmetic device was used on the left cheek for 10 minutes. The speed of moving the beauty machine was 60 round trips per minute according to the metronome, and the strength of pressing the roller 11 against the skin was the strength that the person felt comfortable.

After the test, each subject was evaluated with a feeling of warmth (pump feeling) after use as a perfect score of 4.7. The average was 4.7 points for the cosmetic device 5, and the average 3.7 points for the cosmetic device of the comparative example. The result was obtained. From this test, it can be seen that the presence of the grooves 15 makes the skin warmer.
