When opening a zipper of trousers or the like and searching for the window of the underwear during urination, it is actually very difficult to find. Further, when using so-called step-ins or thigh-length underwear, it is even more difficult to find. In the case of men's underwear of a short length without a window, the penis is taken out from the hem opening for urination, but currently it is difficult to find the hem opening. 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0003】 Conventional men's underwear has the weakness that it is difficult to find the window for exposing the penis during urination. When in a hurry to urinate or for those with frequent urination, it is extremely inconvenient. When using step-ins, thigh-length underwear or the like, it is even more inconvenient. Further, in the case of short underwear without a window, when trying to expose the penis from the hem opening during urination, it is actually difficult to find the hem opening. The present invention solves these problems of men's underwear. 【Means for Solving the Problems】 【0004】 The present invention is to make the cross-section of the edge part into a shape different from other sewing parts, such as a triangle, a semi-circle, a trapezoid, a square, a rectangle, etc., so that it is easy to find with the hand the window used for exposing the penis during urination or the like, and to make the width of the edge part wider than that of the current product. The edge material can be any common fiber, but it should be one of the following that is easily tactile: silicone rubber, natural rubber, synthetic rubber, a mixture of natural and synthetic rubber, nitrile rubber, or a material coated with urethane resin. Materials with protruding spots or a rough surface on the edge are also acceptable. Also, a rim should be provided at the bottom. These means, either individually or in combination, will solve the above problems. [Effects of the Invention] 【0005】 By designing men's underwear in the manner described above, the opening and hem become easier to find when urinating. As a result, the frustration of searching for the opening and hem during urination is reduced, making it extremely convenient for those who are in a hurry to urinate or who urinate frequently, and also reducing the soiling of underwear by urine. Furthermore, by paying attention to the color and design of the edges, the fashion aspect can be improved, allowing for the enjoyment of stylish underwear.

The rim may also have protruding spots or a rough texture on its surface. [Figure 3] This is a diagram showing an embodiment of the first, second, third, fourth, and fifth embodiments of the present invention for long-length men's underwear. The cross-section of the edge can be a semicircle, trapezoid, triangle, square, or rectangle. The height of the edge can be approximately 2 mm to 10 mm. The material of the edge can be general fibers, silicone rubber, natural rubber, synthetic rubber, a mixture of natural and synthetic rubber, nitrile rubber, or a material coated with urethane resin. The edge may also have protruding spots or a rough surface. [Figure 4] This is a diagram showing an embodiment of the first, second, third, fourth, and fifth embodiments of the present invention for trunk-type shorts. The cross-section of the edge can be a semicircle, trapezoid, triangle, square, or rectangle. The height of the edge can be approximately 2 mm to 10 mm.

The second aspect of this invention involves increasing the width of the edge, which is currently about 5 mm, to 5 mm or more, making it easier to feel for the window by hand during use. A third aspect of this invention involves using silicone rubber, natural rubber, synthetic rubber, a mixture of natural and synthetic rubber, nitrile rubber, or a material coated with urethane resin as the edge material, thereby making it easier to feel the window area by hand during use. A fourth aspect of this invention is characterized by the use of a material having protruding spots on the surface of the edge. A fifth aspect of this invention is a combination of any or all of the above four aspects. A fifth aspect of this invention is characterized by providing an edge at the hem of short men's underwear.
