[0001] The present invention relates to men's underwear that is equipped with a genital storage section for storing the penis and scrotum on the inner surface of the underwear, and in particular to men's underwear that can firmly hold the penis and scrotum, preventing the scrotum from shaking and rubbing against the thighs, is comfortable to wear, and is highly breathable. [Background technology]

[0002] BACKGROUND ART Various types of men's underwear have been developed to provide a comfortable and pleasant wearing experience. Such prior art is exemplified by Patent Document 1 below. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-49101 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned Patent Document 1 is an invention related to trunks, which have a supporter similar to a hammock on the inside of the underwear, which has the advantage of providing a comfortable fit for the wearer and effectively suppressing the onset of skin diseases. However, because the rear end of the supporter in the longitudinal direction is sewn to the back of the rear fabric part of the trunks body 2 above the crotch part of the trunks body, when worn the supporter comes into contact with the buttocks and constricts the scrotum, which can easily cause discomfort to the scrotum.

[0005] Therefore, the present invention aims to solve the above-mentioned conventional problems and provide men's underwear that can firmly hold the penis and scrotum, prevent scrotal shaking and friction between the scrotum and thighs, and is comfortable to wear and highly breathable.

Means for Solving the Problem

[0006] In order to achieve the above object, the men's underwear of the present invention is men's underwear provided with a crotch storage part for storing the penis and scrotum on the inner surface of the underwear, and the crotch storage part is at a position overlapping the front part, with the upper side sewn to the lower end position of the waist rubber and the lower side sewn to the position of the front crotch, and is composed of a fabric attached in a suspended state like a hammock inside the underwear. The upper side of the fabric is provided with one or more notches, the left and right sides of the fabric are provided with elastic gathers, and in a range of a predetermined length from the central position of the lower side of the fabric toward the upper side, a three-dimensional sewing part is provided in a state where the fabric is three-dimensionally sewn so that the lower region of the crotch storage part bulges toward the front part side. The first feature is that the upper side of the fabric is sewn to the lower end position of the waist rubber in a state where the opening width of the notch is contracted by a predetermined ratio. Further, in addition to the first feature of the men's underwear of the present invention, the gather part includes a high stretch region where the rate of sewing and shrinking the fabric in the length direction of the left and right sides of the fabric is the largest, a low stretch region where the rate of sewing and shrinking the fabric in the length direction of the left and right sides of the fabric is the smallest, and a medium-high stretch region where the rate of sewing and shrinking the fabric in the length direction of the left and right sides of the fabric is between the high stretch region and the low stretch region. The second feature is that the low stretch region, the high stretch region, and the medium stretch region are arranged in this order from the upper end to the lower end of the left and right sides of the fabric. Furthermore, in addition to the first or second characteristic, the men's underwear of the present invention has a third characteristic in that the placket is made up of a pair of pieces of fabric of the same size arranged one on top of the other, the pair of pieces of fabric having an obliquely sloping edge on each upper edge, the pair of pieces of fabric being arranged symmetrically with a vertical line passing through the horizontal center of the placket as the axis of symmetry so that the pair of sloping edges intersect at approximately the center of the placket, and each sloping edge of the pair of pieces of fabric is an unsewn edge that is not sewn together, thereby providing an exposed region above the position where the pair of sloping edges intersect, and the genitals storage portion has one notch each near the left and right ends of the upper edge, and the fabric of the genitals storage portion is exposed in the exposed region. Furthermore, in addition to the third feature, the men's underwear of the present invention has a fourth feature in that a stretchable fabric or rubber tape is sewn to the inclined sides. [Effects of the Invention]

[0007] According to the men's underwear of the first aspect, the genitals storage section is attached in a hammock-like floating state within the underwear, and by providing elastic gathers on the left and right sides, the genitals storage section can follow the movement of the body and firmly hold the penis and scrotum in place whether the wearer is standing or sitting. This prevents the penis and scrotum from shaking and prevents the scrotum from rubbing against the thighs. This results in men's underwear that is comfortable to wear. Furthermore, by providing a cutout portion on the upper edge of the fabric forming the genitals storage portion, and by sewing the upper edge of the fabric forming the genitals storage portion to the lower end of the waist elastic with the opening width of the cutout portion contracted by a predetermined percentage, and by providing a three-dimensional stitching portion within a predetermined length from the center of the lower edge toward the upper edge, the genitals storage portion can be suitably bulged out toward the placket. This makes it possible to provide a genitals storage portion with a suitable depth despite its simple configuration. Therefore, it is possible to provide men's underwear that supports the scrotum from below and can hold the scrotum in a state where it is moderately bulged out toward the placket when worn. Furthermore, by providing the cutout portion, the men's underwear can be made highly breathable.

[0008] Further, according to the men's underwear according to the second feature, in addition to the effects according to the first feature, in the gather portion, a low-elastic region, a high-elastic region, and a medium-elastic region where the rate of sewing and shrinking the fabric in the length direction of the left and right sides of the fabric are different are arranged in this order from the upper end to the lower end of the left and right sides of the fabric, so that it is possible to form a crotch storage portion that can more closely follow the movement of the body and firmly hold the penis and scrotum.

[0009] Further, according to the men's underwear according to the third feature, in addition to the effects according to the first or second feature, by providing non-sewn sides where the inclined sides of a pair of fabrics are not sewn, an exposed area is provided above the position where the pair of inclined sides intersect, and by exposing the fabric of the crotch storage portion in the exposed area, it is possible to make the men's underwear more breathable. Also, during urination, the penis can be easily taken out of the underwear from the exposed area, making the men's underwear highly convenient. Further, as the configuration of the crotch storage portion, by providing one notch each near the left and right end portions of the upper side, it is possible to effectively suppress the direct visibility of the skin from the exposed area, making the men's underwear.

[0010] Further, according to the men's underwear according to the fourth feature, in addition to the effects according to the third feature, by sewing a stretchable fabric or a rubber tape to the inclined side, a function can be added to lift the crotch storage portion that bulges toward the front part during wearing, making the men's underwear excellent in the holding force of the penis and scrotum.

[0012] Hereinafter, a description of men's underwear according to an embodiment of the present invention will be given with reference to the accompanying drawings to aid in understanding the present invention. However, the following description does not limit the present invention as defined in the claims. In addition, in Fig. 1 and Fig. 3 to Fig. 5, the sewing line is shown by two lines for the sake of convenience of explanation.

[0013] First, with reference to Figs. 1 to 3, a description will be given of men's underwear 1 according to a first embodiment of the present invention. As shown in FIG. 1, men's underwear 1 according to the first embodiment of the present invention is a so-called boxer shorts-type men's underwear comprising a front body 10 with a placket 11, a back body 20, a crotch section 30, a front gusset 2, a back gusset 3, and an elastic waistband 40, and is provided with a genitals storage section 50 for storing the penis and scrotum N on the inner surface of the underwear. It should be noted that the men's underwear equipped with the characteristic genitals storage section 50 of the present invention is not limited to the boxer shorts type as in this embodiment, but may be other men's underwear such as briefs type pants or trunks type pants.

[0014] As described above, this men's underwear 1 is characterized by including a crotch storage part 50, and other configurations, fabric materials, etc. are the same as those of general boxer shorts - type men's underwear. Therefore, in the following, only the crotch storage part 50, which is a feature of the present invention, will be described in detail. As the fabric of the men's underwear 1, for example, various fabrics commonly used as the fabric of men's underwear such as modal can be used, but preferably, a stretchable fabric is desirably used.

[0015] Referring to FIGS. 1 and 2, the crotch storage part 50 according to the embodiment of the present invention is formed of a fabric that is attached in a suspended hammock - like state inside the men's underwear 1. The upper side is sewn at the lower end position of the waist rubber 40, and the lower side is sewn at the position of the front crotch 2 at a position substantially overlapping with the front part 11 formed by sewing a pair of fabrics of the left front part 11a and the right front part 11b that are symmetrically shaped. In this embodiment, as the fabric forming the crotch storage part 50, a stretchable fabric is used. Also, as shown in FIG. 3(b), a fabric is used in which the width E of the lower side of the crotch storage part 50 is smaller than the width F of the upper side. Here, the overall outer shape of the crotch storage part 50 including the width E of the lower side and the width F of the upper side, and the degree of curvature and inclination of the left and right sides are desirably such that the left and right sides of the crotch storage part 50 are easily along the groin of the wearer when worn. Also, a fabric having a deodorizing function may be sewn on the back surface (the surface on the front part 11 side) of the crotch storage part 50 that does not come into contact with the penis and scrotum N. As the fabric having a deodorizing function, for example, a fabric using TAS:TO (registered trademark) yarn manufactured by Takahara Kako Co., Ltd. can be used.

[0016] Also, at the central position of the upper side of the fabric forming the crotch storage part 50, one notch part 51 formed by a substantially U-shaped notch is provided. By sewing the upper side of the fabric forming the crotch storage part 50 to the lower end position of the waist rubber 40 in a state where the opening width of the notch is contracted by a predetermined ratio, above the crotch storage part 50, it functions to bulge the fabric forming the crotch storage part 11 side. Also, it functions to make it easier to release the air inside the crotch storage part 50 to the outside. Note that the shape of the notch part 51 is not limited to a substantially U-shaped, and can be changed as appropriate. However, considering manufacturing efficiency, wearing comfort, breathability, etc., it is desirable that it is a substantially U-shaped. Also, considering the wearing comfort during wearing, the depth G of the notch part 51 shown in Fig. 3(b) is desirably set to a depth where the tip of the penis does not hit.

[0017] Also, as shown in Fig. 1(a), Fig. 2(b), Fig. 2(c), and Fig. 3(b), in a range of a predetermined length from the central position of the lower side to the upper side of the fabric forming the crotch storage part 50, a three-dimensional sewing part 52 is provided where the fabric is three-dimensionally sewn so that the lower region of the crotch storage part 50 bulges toward the front part 11 side. Note that the length H of the three-dimensional sewing part 52 shown in Fig. 3(b) can be changed as appropriate, but preferably, it is desirable that it is about 70% - 90% of the total length of the left and right sides of the crotch storage part 50.

[0018] Also, as shown in Fig. 3(b), elastic gather parts 53 are provided on the left and right sides of the fabric forming the crotch storage part 50. This gathering part 53 mainly functions to bulge the fabric forming the crotch storage part 50 toward the front part 11 side. Also, in any of the standing state, sitting state, and when returning the penis and scrotum N after urination, the shape of the crotch storage part 50 schematically shown in FIG. 2 (a shape that holds the scrotum N from below and bulges toward the front part 11 side) is maintained. Thereby, it is possible to prevent the penis and scrotum N from swaying laterally, and it functions to firmly hold the penis and scrotum N within the crotch storage part 50 to prevent rubbing between the scrotum N and the thigh T, and to make the crotch storage part 50 follow the movement of the body. Also, in the present embodiment, not only is the fabric forming the crotch storage part 50 sewn and shrunk in the length direction of the left and right sides, but a rubber tape of nylon polyurethane having elasticity is sewn to the entire left and right sides of the fabric forming the crotch storage part 50 where the gathering part 53 is provided, so as to give elasticity to the gathering part 53.

[0019] In addition, as the configuration of the gathering part 53, there are a low stretch region 53a where the rate of sewing and shrinking the fabric in the length direction of the left and right sides of the fabric forming the crotch storage part 50 is the smallest, a high stretch region 53b where the rate of sewing and shrinking the fabric in the length direction of the left and right sides of the fabric forming the crotch storage part 50 is the largest, and a medium-high stretch region 53c where the rate of sewing and shrinking the fabric in the length direction of the left and right sides of the fabric forming the crotch storage part 50 is between the high stretch region 53b and the low stretch region 53a. It is configured to arrange the low stretch region 53a, the high stretch region 53b, and the medium stretch region 53c in this order from the upper end to the lower end of the left and right sides. That is, in the present embodiment, in the upper region of the crotch storage portion 50, the crotch storage portion 50 can bulge toward the pubic portion 11 by the notch portion 51, and there is almost no contact with the penis and scrotum N. Rather than the function of holding the penis and scrotum N, the upper region that needs to play the role of firmly suspending the entire crotch storage portion 50 is the low stretch region 53a. Also, in the lower region of the crotch storage portion 50, since the three-dimensional sewing portion 52 can bulge the crotch storage portion 50 toward the pubic portion 11, this region is the medium stretch region 53c. On the other hand, the central region of the crotch storage portion 50 where the notch portion 51 and the three-dimensional sewing portion 52 are not arranged is the high stretch region 53b.

[0020] Note that the rate of sewing and shrinking the fabric in the length direction of the left and right sides of the fabric forming the crotch storage portion 50 in the low stretch region, medium stretch region, and high stretch region can be appropriately changed. Preferably, with respect to the length of the original fabric before sewing and shrinking the fabric in each region, the low stretch region is 95% - 100%, the medium stretch region is 80% - 85%, and the high stretch region is about 50% - 55%. That is, the low stretch region in the present invention includes the case where the original fabric is not sewn and shrunk in the length direction of the left and right sides. Also, the ratio of the length of each region of the low stretch region, medium stretch region, and high stretch region to the total length of the left and right sides of the crotch storage portion 50 can be appropriately changed. However, considering the depth G of the notch portion 51 and the length H of the three-dimensional sewing portion 52, preferably, the low stretch region is about 42% - 44%, the medium stretch region is about 17% - 18%, and the high stretch region is about 38% - 39%.

[0021] The crotch storage portion 50 having such a configuration can be formed, for example, by the following manufacturing method and sewn to the front body 10. First, as shown in FIG. 3(a), a fabric is prepared which has a substantially U-shaped notch 51 on the upper side and a substantially triangular notch 54 on the lower side, and the lower part spreads outwards in a bifurcated shape. Then, as shown in FIG. 3(b), nylon-polyurethane rubber tapes (not shown) are sewn on the left and right sides, and the fabric is sewn and shrunk in the length direction of the left and right sides at a predetermined ratio. Thus, a low stretch region 53a, a high stretch region 53b, and a medium stretch region 53c are provided in this order from the upper end to the lower end of the left and right sides of the fabric to form a gather portion 53. And by sewing and closing the notch 54, a three-dimensional sewing portion 52 is formed. After that, as shown by the black arrow in FIG. 3(a), with the opening width (horizontal width) of the notch 51 shrunk by a predetermined ratio, the upper side of the fabric is sewn to the lower end position of the waist rubber 40. Also, the lower side of the fabric is sewn to the position of the front crotch 2. Thus, the crotch storage portion 50 is sewn to the front body 10. Note that the ratio of shrinking the opening width (horizontal width) of the notch 51 can be changed as appropriate. For example, when the horizontal width of the notch 51 shown in FIG. 3(a) is about 4 cm, it is desirable to set the ratio such that both the left arm portion 51a and the right arm portion 51b are sewn inwards by about 1 cm from the arrangement positions of the left arm portion 51a and the right arm portion 51b before shrinking shown in FIG. 3(a). Also, the formation order of the three-dimensional sewing portion 52 and the gather portion 53 is not limited to the above configuration, and the gather portion 53 may be formed after the three-dimensional sewing portion 52 is formed.

[0022] The men's underwear 1 according to the first embodiment of the present invention having the above configuration has the following effects.

[0023] The crotch storage part 50 is attached in a state of floating in a hammock shape inside the men's underwear 1, and is provided with elastic gathers 53 on the left and right sides. Thus, in any of the standing state, the sitting state, and when returning the penis and scrotum N after urination, the shape of the crotch storage part 50 schematically shown in FIG. 2 is maintained (the standing state of the gathers 53 constituting the side walls of the crotch storage part 50 is maintained to hold the scrotum N from below, and the shape bulging toward the front part 11 side is maintained). As a result, the penis and scrotum N can be prevented from swaying laterally, and the penis and scrotum N can be firmly held inside the crotch storage part 50 to prevent rubbing between the scrotum N and the thigh T. Further, the crotch storage part 50 can follow the movement of the body, and the penis and scrotum N can be firmly held in any of the standing state and the sitting state. Therefore, the men's underwear 1 with excellent wearing comfort can be obtained. Such an effect is a more significant effect in the sitting state shown in FIG. 2(c) where the contact range between the crotch storage part 50 and the thigh T becomes larger by bending the lower body in a direction intersecting the upper body than in the standing state shown in FIG. 2(b).

[0024] Further, the upper side of the fabric forming the crotch storage part 50 is provided with a notch part 51, and the upper side of the fabric forming the crotch storage part 50 in a state where the horizontal opening width of the notch part 51 is contracted by a predetermined ratio is sewn to the lower end position of the waist rubber 40. Thus, the position near the upper end part of the crotch storage part 50 (the position near the sewing part of the crotch storage part 50 and the waist rubber 40) is a position where it is not necessary to bulge toward the front part 11 side. At this position, the upper region of the crotch storage part 50 can be suitably bulged toward the front part 11 side without causing excessive sagging of the fabric (excessive bulging toward the front part 11 side). Furthermore, by providing a three-dimensional sewing part 52 in a range of a predetermined length from the central position of the lower side to the upper side of the fabric forming the crotch storage part 50, the lower region of the crotch storage part 50 can be suitably bulged toward the front part 11 side. With these cutout portions 51 and three-dimensional sewing portions 52, it is possible to form a crotch storage portion 50 having a suitable depth while having a simple configuration. Therefore, when worn, the male underwear 1 can support the scrotum N from below and hold the penis and scrotum N in a state where they bulge moderately toward the front part 11 side. In addition, by providing the cutout portions 51, the male underwear 1 can be made highly breathable.

[0025] Also, in the gather portion 53, by arranging three regions, namely, a low stretch region 52a, a high stretch region 52b, and a medium stretch region 52c, in this order from the upper end to the lower end of the length direction of the left and right sides of the fabric forming the crotch storage portion 50, with different rates of sewing and shrinking the fabric, it is possible to form a crotch storage portion 50 that can more firmly hold the penis and scrotum N following the movement of the body.

[0026] As described above, while having the common function of bulging the crotch storage portion 50 including the cutout portions 51, three-dimensional sewing portions 52, and gather portions 53 toward the front part 11 side, three parts with different specific structures and configurations are provided in one crotch storage portion 50. Also, with a configuration where the width E of the lower side of the crotch storage portion 50 formed of stretchable fabric is smaller than the width F of the upper side, it is possible to firmly hold the penis and scrotum N in the crotch storage portion 50 along the groin of the wearer in any situation, prevent the swaying of the scrotum N and the rubbing between the scrotum N and the thigh, provide a good wearing feeling, and prevent the displacement of the penis and scrotum N, thus making the male underwear 1.

[0027] Further, by sewing the upper side of the crotch storage portion 50 at the lower end position of the waist rubber 40, the upper side of the crotch storage portion 50 can follow the stretching and shrinking of the waist rubber 40, and the male underwear 1 can be made such that it is easier for each wearer to make the crotch storage portion 50 follow the groin more closely.

[0028] Also, by sewing the lower side of the crotch storage part 50 to the position of the front crotch 2, in the worn state, the crotch storage part 50 does not move to the hip side and the scrotum N is not constricted, and the men's underwear 1 with excellent wearing comfort can be obtained.

[0029] Next, with reference to FIGS. 4 and 5, the men's underwear 4 according to the second embodiment of the present invention will be described. The men's underwear 4 according to the second embodiment of the present invention is obtained by changing the configuration of the front part 11 and the configuration of the crotch storage part 50 with respect to the men's underwear 1 according to the first embodiment of the present invention described above. Other configurations are the same as those of the men's underwear 1 according to the first embodiment of the present invention described above. Therefore, the same members as those of the men's underwear 1 according to the first embodiment of the present invention described above and having the same functions are assigned the same numbers, and the following detailed description will be omitted.

[0030] Referring to FIG. 4(a), as the configuration of the front part 11, a pair of fabrics of the same size are arranged by being overlapped symmetrically with respect to a line (symmetric left and right) in the front and back. Specifically, referring to FIG. 4(c), the upper side is composed of an inclined side K that slopes downward from the right end toward the left side L, the right side J is composed of a vertical side, the left side L is composed of a substantially vertical side with a slightly curved lower region facing inward, and the lower side M is composed of a horizontal side. The left front stand 11c is composed of a quadrilateral, and the right front stand 11d is composed of a pentagon with a horizontal side S extending from the right end, an upper side composed of an inclined side K that slopes downward from the left end of the horizontal side S toward the left side Q, a right side P composed of a vertical side, a left side Q composed of a substantially vertical side with a slightly curved lower region facing inward, and a lower side U composed of a horizontal side. The first fabric 110 is formed by sewing the right side J and the left side Q. Further, a second fabric 120 having a shape symmetric to the first fabric 110 is provided. As shown in FIG. 4(a), with a vertical line passing through the horizontal center of the front stand 11 (shown by a dashed line in FIG. 4(a)) as the axis of symmetry, the inclined side K of the first fabric 110 and the inclined side K of the second fabric 120 intersect at a substantially central position. In this state where a pair of the first fabric 110 and the second fabric 120 are arranged symmetrically in the front and back, the entire outer edge (outer perimeter) of the first fabric 110 and the second fabric 120 excluding the inclined side K of the first fabric 110 and the inclined side K of the second fabric 120 is sewn to the end of the fabric of the front body 10 excluding the front stand, the end of the fabric of the crotch part 30, and the end of the waist rubber 40. More specifically, in this embodiment, the first fabric 110 is arranged on the front side and the second fabric 120 is arranged on the back side, and the first fabric 110 and the second fabric 120 are sewn together so that three locations, namely, the right side of the first fabric 110 and the right side of the second fabric 120, the left side of the first fabric 110 and the left side of the second fabric 120, and the lower side of the first fabric 110 and the lower side of the second fabric 120, overlap in the front and back. That is, the upper side of the first fabric 110 and the upper side of the second fabric 120 are non-sewn sides that are not sewn. Note that "substantially central" in the above refers to a range of about 1 cm to the left and right across the central positions of the inclined side K of the first fabric 110 and the inclined side K of the second fabric 120. With such a configuration, as shown in Fig. 4(a), an exposed area R is provided above the position where the inclined side K of the first fabric 110 and the inclined side K of the second fabric 120 intersect, and the fabric of the crotch storage portion 50 is exposed in this exposed area R. Furthermore, in the present embodiment, rubber tapes are sewn to the inclined side K of the first fabric 110 and the inclined side K of the second fabric 120. Note that a configuration in which a stretchable fabric is sewn instead of the rubber tape may also be adopted.

[0031] In addition, as the configuration of the crotch storage portion 50, one notch portion 51 is provided at each of the left and right end portions in the vicinity of the upper side of the crotch storage portion 50, for a total of one pair (two pieces). Here, the "vicinity of the left and right end portions" means a range within about 2.5 cm from the left and right end portions of the crotch storage portion 50. Also, the size, arrangement position of the pair (two pieces) of notch portions 51, and the ratio of shrinking the opening width of the notch portion 51 by a predetermined ratio can be appropriately changed. However, in order to prevent the skin from being directly visible from the exposed area R, it is necessary to configure the notch portion 51 so that it does not protrude from the exposed area R in a state where the upper side of the fabric forming the crotch storage portion 50 with the opening width of the notch portion 51 shrunk by a predetermined ratio is sewn to the lower end position of the waist rubber 40. More specifically, for example, regarding the ratio of shrinking the opening width of the notch portion 51 by a predetermined ratio, when the opening width (lateral width) of the notch portion 51 before sewing shown in Fig. 5(a) is about 2 cm, it is desirable to set the ratio such that both the left arm portion 51a and the right arm portion 51b are sewn in about 1 cm inward from the arrangement positions of the left arm portion 51a and the right arm portion 51b before shrinking shown in Fig. 5(a). Note that in the present embodiment, as shown in Fig. 4(a), the pair of notch portions 51 are configured to be hidden by the horizontal side S constituting the upper side of the first fabric 110 and the horizontal side S constituting the upper side of the second fabric 120.

[0032] By adopting the configuration of the men's underwear 4 according to the second embodiment of the present invention as described above, the following effects can be obtained.

[0033] By exposing the fabric of the crotch storage part 50 in the exposed area R, the men's underwear 4 can be made to have even better breathability. Also, during urination, the penis can be easily taken out of the underwear from the exposed area R, making the men's underwear 4 highly convenient. Moreover, by providing the horizontal side S that constitutes the upper side of the first fabric 110 and the horizontal side S that constitutes the upper side of the second fabric 120, the sewing strength of the front part 11 can be increased, and the men's underwear 4 can effectively prevent the skin from being directly visible from the exposed area R.

[0034] Also, by sewing a rubber tape or stretchable fabric to the inclined side K, a function can be added to lift the crotch storage part 50 that bulges toward the front part 11 during wearing, making the men's underwear 4 even better in holding power for the penis and scrotum N.

[0035] In the men's underwear 4 according to the second embodiment of the present invention described above, the horizontal side S is provided on both the first fabric 110 and the second fabric 120. However, it may be configured such that each upper side is formed only by the inclined side K without providing the horizontal side S. However, the horizontal side S that constitutes the upper side of the first fabric 110 and the horizontal side S that constitutes the upper side of the second fabric 120 both serve as a sewing margin when sewing the upper side of the front part 11 to the lower end position of the waist rubber 40, increasing the sewing strength, and also have the function of preventing the notch part 51 from being exposed in the exposed area R and the skin from being directly visible. Therefore, preferably, it is desirable to adopt a configuration in which the horizontal side S that constitutes the upper side of the first fabric 110 and the horizontal side S that constitutes the upper side of the second fabric 120 are provided. Furthermore, while men's underwear 4 according to the second embodiment of the present invention, as described above, is configured so that first fabric 110 is located at the front and second fabric 120 is located at the back, the configuration is not necessarily limited to this, and it is also possible to configure first fabric 110 at the back and second fabric 120 at the front.
