Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the following drawings, the same reference numerals are given to the same components, and redundant descriptions may be omitted.

[0011] The present invention relates to a cosmetic applicator (for example, a mascara tool, etc.) having an applicator (comb) for applying a liquid such as mascara to eyelashes or hair.

[0012] <First Embodiment> First, with reference to FIG. 2, the overall configuration of the cosmetic applicator according to the first embodiment will be described. FIG. 2 is a diagram showing the overall configuration of a cosmetic applicator including a comb according to the first embodiment of the present invention.

[0013] As shown in FIG. 2, the cosmetic applicator 4 includes a comb (application comb) 1 as an applicator, a shaft portion (support shaft) 2, and a grip portion 3.

[0014] The cylindrical grip portion (lid portion) 3 is attached to the shaft portion 2 and is the portion gripped by the user during use. Further, a female thread is formed on the inner peripheral surface of the outer cylinder of the grip portion 3, and the grip portion 3 can be screwed and engaged with a bottle (container) in which a cosmetic is stored, and functions as a lid portion for the bottle. Note that the shaft portion 2 may be detachable from the grip portion 3 or may be integrally formed.

[0015] The cosmetic applicator 4 according to the present embodiment is a comb-shaped mascara in which the comb portion is integrally formed with the shaft portion. That is, at the tip of the shaft portion 2, a comb 1 which is an applicator for applying a mascara liquid or the like to the eye area is integrally provided. The comb 1 can apply a cosmetic such as a mascara liquid to the eyelashes while separating the eyelashes.

[0016] Cosmetics such as mascara liquid filled in a bottle adhere to the comb 1. The cosmetics adhering to the comb 1 are not limited to mascara liquid (mascara), and may be cosmetics that can be used for multiple purposes such as hair growth agents for eyelashes, mascara bases, eyelash coating agents, coating agents for false eyelashes, eyeliner liquids, and cosmetic compositions for both mascara and eyeliner.

[0017] In the cosmetic applicator 4, at least the shaft portion 2 and the comb 1 are formed by integrally molding a resin. It is desirable to use a thermoplastic resin as the resin material, and for example, elastomers, polyethylene, polypropylene, polystyrene, polyethylene terephthalate, polybutylene terephthalate, polycarbonate, polyacetate, nylon, etc. can be used.

[0018] Next, the details of the comb 1 which is the application body will be described with reference to FIGS. 2 to 6. FIGS. 3 to 6 are enlarged views of the comb 1 according to the first embodiment. FIG. 3 is an explanatory view of the comb according to the first embodiment, FIG. 3(a) is a plan view of the abdominal side, and FIG. 3(b) is a front view. FIG. 4 is a perspective view of the comb according to the first embodiment. FIG. 5 is a bottom perspective view of the comb according to the first embodiment. FIG. 6 is an explanatory view of the upper surface of the comb according to the first embodiment.

[0019] As can be seen from FIGS. 2 to 6, in the present embodiment, in the comb 1, a plurality of protrusions 10 protruding from a pedestal surface (one surface) 18 extending in the axial direction A of the shaft portion 2 with a predetermined width are arranged on the tip side of the shaft portion 2. The protrusion 10 according to the present embodiment is not a flat plate but a bent crank shape.

[0020] In the circumferential direction of the shaft portion 2 in the comb 1, the abdominal side surface where the protrusion 10 is provided is defined as the pedestal surface 18. Also, the back side surface of the comb 1 other than the pedestal surface 18 is defined as the back surface 19.

[0021] On one side, in the axial direction A of the shaft portion 2 in the cam 1, a tip protrusion 16 is provided at the tip of the cam 1. Further, a connecting portion 17 for connecting to the shaft portion 2 is provided at the rear end of the cam 1.

[0022] The plurality of protruding portions 10 are in a crank shape that is line-symmetric with the width direction W as the axis of symmetry, and the first protruding portion 11 and the second protruding portion 12 are alternately provided in the axial direction A.

[0023] The first protruding portion 11 is integrally formed by the first protrusion 13A, the connecting top wall 15A, and the second protrusion 14A. The second protruding portion 12 is integrally formed by the first protrusion 13B, the connecting top wall 15B, and the second protrusion 14B.

[0024] In other words, each protruding portion 10 (11, 12) of the plurality of protruding portions of the cam 1 has the first protrusion 13A or 13B, the second protrusion 14A or 14B, and the connecting top wall 15A or 15B.

[0025] As shown in FIG. 3(a), the first protrusions 13A, 13B are located on the first side edge E1 side in the width direction of the pedestal surface (one surface) 18, and protrude from the root portion that spreads from the first side edge E1 toward the center.

[0026] The second protrusions 14A, 14B are located on the second side edge E2 side facing the first side edge E1 in the width direction of the pedestal surface 18, and protrude from the root portion that spreads from the second side edge E2 toward the center.

[0027] The connecting top walls 15A, 15B connect the central ends in the width direction W of the first protrusions 13A, 13B and the central ends in the width direction W of the second protrusions 14A, 14B at the center in the width direction W of the pedestal surface 18. As shown in FIG. 3(a), the connecting top walls 15A, 15B are longer in the axial direction A than in the width direction W.

[0028] Here, the positions of the first protrusions 13A and 13B and the second protrusions 14A and 14B in the axial direction A are all different. Therefore, the first protrusion 11 according to the present embodiment has a crank shape bent at two locations: the boundary between the first protrusion 13A and the connecting top wall 15A, and the boundary between the connecting top wall 15A and the second protrusion 14A. The second protrusion 12 has a crank shape bent at two locations: the boundary between the first protrusion 13B and the connecting top wall 15B, and the boundary between the connecting top wall 15B and the second protrusion 14B. Also, due to the above configuration, the contours of the root portions of the respective protrusions 11 and 12 of the plurality of protrusions 10 include portions with different positions in the axial direction A.

[0029] Further, at the side edges E1 and E2, which are both ends in the width direction W of the pedestal surface 18 of the cam 1 shown in FIGS. 2, 3(a), and 3(b), the plurality of protrusions 10 are arranged such that wide intervals and narrow intervals alternately open in the axial direction A.

[0030] Specifically, the plurality of first protrusions 13A and 13B are arranged with the first predetermined interval Ga and the second predetermined interval Gb, which is longer than the first predetermined interval Ga, alternately spaced apart in the axial direction. Also, the plurality of second protrusions 14A and 14B are arranged with the second predetermined interval Gb and the first predetermined interval Ga alternately spaced apart in the axial direction A.

[0031] As an example, the first predetermined interval Ga is preferably 0.2 to 0.6 mm, more preferably 0.3 to 0.5 mm, and the second predetermined interval Gb is preferably 1.0 to 1.7 mm, more preferably 1.2 to 1.5 mm. In setting the above intervals, the second predetermined interval Gb is preferably 3 to 4 times the first predetermined interval Ga.

[0032] Connecting the top walls 15A and 15B, the first connecting top wall 15A connects the central end of the first protrusion 13A located on the rear end side in the axial direction A and the central end of the second protrusion 14A located on the front end side in the axial direction A at the first protrusion 11. On the other hand, the second connecting top wall 15B connects the central end of the first protrusion 13B located on the front end side in the axial direction A and the central end of the second protrusion 14B located on the rear end side in the axial direction A at the second protrusion 12. The first connecting top wall 15A and the second connecting top wall 15B are alternately arranged in the axial direction A.

[0033] Also, referring to FIGS. 4 and 5, the first protrusions 13A and 13B and the second protrusions 14A and 14B are flat plates having a substantially right-angled triangle shape with the height increasing toward the center in the width direction W. Also, the first protrusions 13A and 13B and the second protrusions 14A and 14B are symmetrically shaped with the connecting top walls 15A and 15B as the axis of symmetry. Further, the tip protrusion 16 located at the tip beyond the pedestal surface 18 has a substantially isosceles triangle shape with the rear end surface having a height increasing toward the center in the width direction W, and the tip side is rounded. Since the protrusions 11 and 12 including the crank shape are triangular as a whole in the width direction, each of the protrusions 11 and 12 can be easily brought closer to the root of the eyelashes.

[0034] Referring to FIG. 3(b), the height H from the pedestal surface 18 of the connecting top walls 15A and 15B, which is the highest part of the protrusions 11 and 12, is 5 to 7 mm. Also, at the tip portion T in the axial direction A of the comb 1, the tip becomes thinner and the area on the back side becomes narrower toward the tip side. However, even at the tip portion T, since the height of the protrusions 11 and 12 is the same as that of the central portion of the pedestal surface 18, the diameter is thin, and even at the tip portion T used for, for example, the eye corner or the outer corner of the eye, the eyelashes can be combed in the same manner as the central portion.

[0035] Also, referring to FIGS. 4 and 6, the pedestal surface 18 is curved in the width direction so as to be convex in the protruding direction (ventral direction) of the plurality of protrusions 10. For example, the curvature R of the curvature of the pedestal surface 18 shown in FIG. 6(b) is 0.2 to 1.3.

[0036] Here, at the center position in the width direction W of the pedestal surface 18, since the first connecting top wall 15A and the second connecting top wall 15B have a predetermined length in the axial direction A, when the comb 1 is taken out from the bottle at an angle as shown in FIG. 4, mascara liquid can be placed on the upper sides of the first connecting top wall 15A and the second connecting top wall 15B. Thereby, the amount of mascara liquid (including liquid) adhering to the comb 1 of the present embodiment is improved compared to a comb with a linear comb part.

[0037] Furthermore, in the example of FIG. 4, like the space marked with a circle, a plurality of first protrusions 13A, 13B surround a wide second predetermined interval Gb with the first connecting top wall 15A and the second connecting top wall 15B in between. Therefore, the mascara liquid on the upper sides of the first connecting top wall 15A and the second connecting top wall 15B can be carried to the user's eyelashes without being dropped while being supported by the plurality of first protrusions 13A, 13B.

[0038] Similarly, even when tilted with the second side edge E2 side facing up, since a plurality of second protrusions 14A, 14B surround a wide second predetermined interval Gb with the connecting top walls 15B, 15B in between, the mascara liquid on the upper sides of the connecting top walls 15A, 15B can be carried to the user's eyelashes without being dropped while being supported.

[0039] Also, because the pedestal surface 18 is curved on the ventral side, when the comb 1 is taken out from the bottle at an angle as shown in FIG. 4, for example, mascara liquid can also be placed on the curved pedestal surface 18. Therefore, the amount of mascara liquid (including liquid) adhering to the comb 1 of the present embodiment is improved compared to a comb with a flat plate-shaped pedestal surface.

[0040] Furthermore, when combing the eyelashes with the comb 1 of the present embodiment, the eyelashes that enter the wide second predetermined interval Gb surrounded by the crank-shaped protrusions 11, 12 come out through the narrow first predetermined interval Ga. Therefore, by combing while squeezing the nearby hairs, the direction of the tips of the eyelashes is aligned, and the eyelashes are separated into small bundles, resulting in a bundled feeling in the eyelashes and enhancing the impression of the eyelashes.

[0041] Thus, the cosmetic applicator 4 provided with the comb 1 according to the present embodiment can arrange the eyelashes in a desired direction and create a tufted feeling with a minimum operation of combing the eyelashes, without using, for example, a separate finishing metal mascara comb, the bristles on the back side as shown in FIG. 1, or tweezers. As a result, the stress caused by lumps is reduced for the user, the satisfaction with the state of the eyelashes after mascara application is increased, and the time required for makeup can be saved.

[0042] (Experimental Example 1) Here, the present applicants conducted a questionnaire survey on the finish after using the comb 1 according to the first embodiment for 10 female subjects. FIG. 10 is a diagram showing the questionnaire results of the finish after using the comb 1 according to the first embodiment.

[0043] In the present embodiment, the content of the mascara liquid is a black fiber-free mascara. The fiber-free mascara liquid tends to result in a more natural finish than the fiber-containing mascara.

[0044] In this experiment, regarding the comb 1 of the first embodiment (1) An unused comb 1 was placed in a bottle containing the content (mascara liquid), and the cosmetic applicator equipped with the comb 1 was rotated left and right three times to allow the comb to adapt well to the content liquid. (2) The mascara liquid adhered to the comb 1 was applied to the left and right eyelashes 20 times each. (3) The finish of the eyelashes after application was evaluated. At the time of evaluation, the subjects evaluated the finish of their own eyelashes reflected in a desktop mirror, a wash mirror, and / or a wall-mounted mirror.

[0045] The evaluation items were "a uniform finish without lumps", "a finish with the eyelashes evenly separated", "a finish with the eyelashes lengthened", "a finish with the eyelashes thickened", and "a finish with the eyelashes having stiffness", and the 10 subjects were allowed to give multiple answers per person.

[0046] As shown in Fig. 7, it can be seen that among the ten subjects, the evaluation of the finished eyelashes using the comb 1 of the present embodiment as "the finished eyelashes with uniformly separated eyelashes" is the most common.

[0047] (Experimental Example 2) In order to compare the usage status of the shape of the present embodiment with the shape of the comparative example, the inventors of the present application made a comparison with the comparative example. Fig. 8 is an explanatory diagram of the comb (coating body) according to the comparative example used in the experiment. Fig. 8(a) is a perspective view of the comb according to the comparative example, and Fig. 8(b) is a plan view of the abdomen of the comb.

[0048] The axial length of the pedestal surface 87 of the comb 8 according to the comparative example is the same as the axial length of the pedestal surface 18 of the first embodiment. The pedestal surface 87 is curved in the width direction so as to be convex in the protruding direction (abdomen direction) of the plurality of protruding portions 81, and the curvature R of the curvature is the same as that of the first embodiment.

[0049] The protruding portion 81 which is the comb part has a straight shape without a step in the axial direction, and has a substantially isosceles triangle flat plate shape in which the curved surface portion of the pedestal surface 18 is recessed. The tip angle of the protruding portion 81 is the sum of the apex angles of the first protrusions 13A, 13B and the second protrusions 14A, 14B of the first embodiment, and the protruding amount of the height in the protruding direction of the protruding portion 81 is the same as the height of the connecting top walls 15A, 15B of the first embodiment. As shown in Fig. 8(b), the protruding portions 81 of the comb 8 are arranged at equal intervals in the axial direction, and the interval G8 between the protruding portions 81 on the pedestal surface 87 is equal to the narrower interval (the first predetermined interval) Da of the first embodiment.

[0050] In this experiment, the content of the mascara liquid is a black fiber-free mascara, and the subjects were ten women. The comb A used in the experiment is the comb 1 of the first embodiment, and the comb B is the comb 8 of the comparative example. However, the subjects were not informed which comb corresponded to either the present invention (under development) or the comparative example (already on the market as a product). (1) Place unused combs (Comb A, Comb B) into a bottle containing the essence liquid, and rotate the cosmetic applicators each equipped with Comb A and Comb B left and right three times to allow the combs to thoroughly absorb the essence liquid. (2) For each person, apply Comb A and Comb B with the mascara liquid to the left and right eyelashes 20 times each. (3) After application, compare and evaluate the finish of the left and right eyelashes. During the evaluation, the subjects evaluated the finish of their own eyelashes reflected in a desktop mirror, a washroom mirror, or / and a wall-mounted mirror. Note that for each person, it was left to decide whether to apply with Comb A and Comb B to the left or right eyelashes.

[0051] Figure 9 is a diagram showing the questionnaire results of the finish after using the combs according to the first embodiment and the comparative example.

[0052] The evaluation items were "uniform finish with Comb A separated", "uniform finish with Comb A slightly separated", "both the same", "uniform finish with Comb B slightly separated", "uniform finish with Comb B separated", and 10 subjects gave one answer each.

[0053] As shown in Figure 9, the total number of people who answered "uniform finish with Comb A separated" and "uniform finish with Comb A slightly separated" was 7, which was more than the 1 person who answered "uniform finish with Comb B separated". From this, it can be seen that Comb A, that is, the comb 1 according to the first embodiment, has an effect of making people feel a "separated and uniform finish" more than Comb B, that is, the comb 8 according to the comparative example.

[0054] (Experimental Example 3) Furthermore, the inventors took photos of the eyes of two subjects regarding the finish of Experimental Example 2. Figure 10 is a photograph showing the finish after using the combs 1 and 8 according to the first embodiment and the comparative example.

[0055] As shown in the left photograph, when applying mascara liquid with the straight comb-shaped comb 8 according to the comparative example, the eyelashes are radially separated one by one or in groups of two or three. In Fig. 10, due to the zoomed-in shooting, even if each eyelash is separated, it is visible. However, when the distance is more than 45 cm, which is the solid distance for the sense of distance with friends or acquaintances, or more than 120 cm, which is the social distance for the distance with business partners, the applied eyelashes may not be clearly visible because they are subdivided and separated.

[0056] On the other hand, as shown in the right photograph, when applying mascara liquid with the comb 1 according to the first embodiment, several eyelashes are gathered together to form a tuft of hair, and the tufts of hair are at natural intervals. It is considered that the comb 1 combs while narrowing down the hairs near the wider interval Gb, thus aligning the directions of the tips of the eyelashes.

[0057] The face including the eyelashes is assumed to be viewed from a distant position. In the questionnaire results in Fig. 9 above, the subjects evaluated by looking at a mirror at a certain distance rather than a hand mirror. From Figs. 9 and 10, it can be seen that when the eyelashes are intentionally bundled by the comb 1 to create a tufted feeling, the eyelashes can be clearly seen separated from a certain distance.

[0058] Thus, the cosmetic applicator equipped with the comb 1 according to the first embodiment of the present invention can align the eyelashes in a desired direction and create a tufted feeling with only the minimal operation of combing the eyelashes, without using a separate finishing mascara comb or changing the usage location on the shaft as shown in Fig. 1.

[0059] (Experimental Example 4) The present subjects conducted a comparative experiment on the liquid attachment of the comb. Fig. 11 is a diagram of the liquid attachment of the comb according to the first embodiment and the comparative example.

[0060] Note that the essence liquid of the mascara used in this experiment is a black mascara liquid containing the so-called fibers of the black mascara liquid. The essence contains the following components. Hydrogenated polyisobutene, cyclomethicone, trimethylsiloxysilicic acid, dextrin palmitate, polyethylene, microcrystalline wax, isostearic acid, triethylhexanoin, polymethylsilsesquioxane, nylon-6, tocopherol acetate, macadamia nut oil, BHT, silica, tocopherol, carbon black.

[0061] (Experimental method) (1) Unused combs (Comb A, Comb B) were placed in a bottle containing the essence liquid, and the cosmetic applicators equipped with Comb A and Comb B were rotated three times to the left and right to make the combs well-acquainted with the essence liquid. (2) The state of the liquid on the combs (Comb A, Comb B) when the combs were pulled out of the bottle was photographed. (3) The state of adhesion to the cotton (Comb A, Comb B) when the combs were gently pressed against the cotton was photographed. The above operations were performed five times, and the best one is shown in Fig. 11.

[0062] As is clear from the photograph in Fig. 11, in both the comparative example and the present embodiment, the mascara liquid adheres uniformly to the combs. Also, when comparing Comb 1 according to the first embodiment with Comb 8 according to the comparative example regarding the comb body, in the comparative example, the protruding portion 81 has an observable adhesion amount, while in the first embodiment, the liquid adheres so much that the protruding portions 11 and 12 are hidden, indicating that there is a large amount of liquid adhering to Comb 1 (liquid-containing).

[0063] Also, when comparing Comb 1 according to the first embodiment with Comb 8 according to the comparative example regarding the cotton, in the comparative example, the mascara liquid adheres in a thin and evenly spaced manner at intervals D8, while in the first embodiment, a large amount of the mascara liquid adheres in a concentrated manner at wider intervals Db, indicating that the adhesion amount to the cotton is large.

[0064] As a result, the comb 1 according to the first embodiment can attach more mascara liquid than the comb 8 according to the comparative example. Therefore, it can be said that the comb 1 according to the present invention can increase the amount of attachment to the eyelashes per combing operation.

[0065] <Second Embodiment> Next, with reference to FIG. 12, a cosmetic applicator according to the second embodiment of the present invention will be described. FIG. 12 is an explanatory view of the tip of the comb 5 according to the second embodiment of the present invention. The comb 5 shown in FIG. 12 is a part on the tip side of the comb 5 in a cosmetic applicator including a gripping portion 3 and a shaft portion 2.

[0066] In the present embodiment, on the tip side of the shaft portion 2, a plurality of protruding portions 50 protruding from a pedestal surface (one surface) 53 extending in a predetermined width in the axial direction of the shaft portion are arranged side by side. The comb 5 according to the present embodiment has a pedestal surface 53 on the abdomen side and a back surface 54.

[0067] The plurality of protruding portions 50 of the present embodiment have a flat plate-shaped first protruding plate 51 and a second protruding plate 52.

[0068] The first protruding plate 51 is inclined with respect to the axial direction such that the first side edge E3 side of the pedestal surface (one surface) 53 is located on the tip side in the axial direction and the second side edge E4 side facing the first side edge E3 is located on the rear end side. The second protruding plate 52 is inclined with respect to the axial direction such that the first side edge E3 side of the pedestal surface 53 is located on the rear end side and the second side edge E4 side is located on the tip side. With such a shape, in the present embodiment, the contour of the base portion of each protruding plate 51, 52 includes portions having different axial positions. The first protruding plate 51 and the second protruding plate 52 are alternately provided in the axial direction.

[0069] Further, as shown in FIG. 12, the first protruding plate 51 and the second protruding plate 52 are flat plate-shaped and are isosceles triangle-shaped that become higher toward the center in the width direction. By each of the protruding plates 51, 52 being isosceles triangle-shaped, the protruding plates 51, 52 can be easily brought closer to the root of the eyelashes.

[0070] In the present embodiment, at the side edges E3 and E4 which are both ends in the width direction orthogonal to the axial direction of the pedestal surface 53, the protruding plates 51 and 52 are arranged such that wide intervals Gc and narrow intervals Gd alternate in the axial direction.

[0071] In the arrangement state where the first protruding plate 51 and the second protruding plate 52 alternate, it is preferable that the plate-to-plate distance (first predetermined interval) Gc on the narrow side is 0.3 to 0.5 mm, and the plate-to-plate distance (second predetermined interval) Gd on the wide side is 1.2 to 1.5 mm. And it is preferable that the plate-to-plate distance Gd on the wide side is 3 to 4 times the plate-to-plate distance Gc on the narrow side.

[0072] When combing the eyelashes with the comb 5 according to the present embodiment shown in FIG. 12, the eyelashes that have entered the enclosed wide second predetermined interval Gd come out through the first predetermined interval Gc which is a narrow space. Therefore, by combing while squeezing the nearby hairs, the eyelashes are separated (separated) into small bundles, and the direction of the tips of the eyelashes is aligned.

[0073] In this way, the cosmetic applicator provided with the comb 5 according to the present embodiment can align the eyelashes in a desired direction and create a bundled hair feeling with only the minimum operation of combing the eyelashes.

[0074] <Third Embodiment> FIG. 13 is an explanatory view of a comb 6 according to the third embodiment of the present invention. FIG. 13(a) is a plan view of the abdominal side, and FIG. 13(b) is a perspective view of the tip of the shaft portion. The comb 6 shown in FIGS. 13(a) and 13(b) is a part on the tip side of the comb 6 in a cosmetic applicator including a grip portion 3 and a shaft portion 2.

[0075] In the present embodiment, a plurality of protruding portions 61 protruding from a pedestal surface (one surface) 62 extending in a predetermined width in the axial direction of the shaft portion are arranged on the tip side of the shaft portion.

[0076] In the present embodiment, the plurality of protruding portions 61 are in the shape of a quadrangular pyramid with a bulge at the center in the width direction so as to be diamond-shaped when viewed from the front direction of the pedestal surface (one surface) 62. Specifically, the plurality of protruding portions 61 are in the shape of a quadrangular pyramid with the diagonal portion of the diamond shape in the front view as a side, the long diagonal of the diamond in the front view extends in the width direction, and the short diagonal extends in the axial direction. With such a shape, the contour of the base portion of each of the plurality of protruding portions 61 includes portions with different axial positions.

[0077] In the present embodiment, in the central direction of the pedestal surface 62, the same protruding portions 61 are arranged axially, and at the tip of the pedestal surface 62, a plurality of similar protruding portions 61 that become smaller toward the tip side are arranged.

[0078] Since the plurality of protruding portions 61 are in the shape of a quadrangular pyramid, the cross section in the width direction of each protruding portion 61 is an isosceles triangle shape. Because the cross section in the width direction of each protruding portion 61 is an isosceles triangle shape, it becomes easier to bring the protruding portion 61 closer to the root of the eyelash.

[0079] In the present embodiment, it is preferable that the axial protruding portion interval (spacing) Ge between the vertices defining the long diagonal of the adjacent rhombus in the front view, that is, both ends in the width direction of the protruding portion 61, is 0.3 to 0.5 mm. Also, it is preferable that the axial protruding portion interval (spacing) Gf between the vertices defining the short diagonal of the adjacent rhombus in the front view, that is, the center in the width direction of the protruding portion 61, is 1.2 to 1.5 mm.
