Item 6. The sports bra according to any one of items 1 to 5, wherein the sports bra is configured.
Item 7. Item 7. The sports bra according to Item 6, wherein the breast outer peripheral fabric portion 6 is formed of a Russell knitted fabric.

  Hereinafter, the sports bra of the present invention will be described in detail.

  The sports bra of the present invention includes a front cloth portion 2 that covers a chest including left and right breasts, a pair of shoulder cloth portions 3 that extend from the upper portion of the front cloth portion 2 and are stretched over left and right shoulders, and the front cloth portion 2. A sports bra 1 comprising a back cloth part 4 extending from both sides to the back and connected to the shoulder cloth part 3, the front cloth part 2 and an under part 5 connected to the lower end of the back cloth part 4. The outer peripheral edge cloth part 6 is provided inside the front cloth part 2 so as to surround the outer peripheral edge of the breast from the upper side to the both sides, and both ends thereof are separately connected to the under part 5. The sports bra is made of a material having lower elasticity than the front cloth portion 2. By using a material having lower elasticity than the front cloth part 2 as the outer peripheral cloth part 6, it is possible to have a function of suppressing breast shaking during exercise.

  The material of the front fabric portion 2 is not particularly limited as long as it is a knitted fabric that fits the body appropriately according to the movement. For example, a mesh of a milled knitted fabric is preferable in terms of lightness and air permeability.

  The material of the shoulder cloth part 3 and the back cloth part 4 is not particularly limited as long as it is a stretchable fabric in order to improve the ease of movement. For example, a milled knitted fabric or a mesh fabric is suitable.

  The material of the under part 5 is not particularly limited as long as it is a fabric or rubber that is stretchable and fits the body appropriately so that the sports bra 1 is fitted so as not to slide up when worn during exercise. For example, a milled knitted fabric using an elastic yarn is suitable from the viewpoint of air permeability and touch.

  As the material of the outer periphery peripheral fabric portion 6, a fabric having a lower elasticity than the front fabric portion 2, which plays a role of stopping the stretch of the front fabric portion 2 in order to suppress the shaking of the breast during exercise, is used. For example, it is preferable to use a knitted fabric having an elongation rate under constant load (cut strip method 2.5 cm × 20 cm, 9.81 N) according to the JIS-L-1018 test of 230 to 270% in length and 65 to 85% in width. Particularly preferred is a Russell knitted fabric.

  The breast shielding part 7 is made of a transparent cloth having a certain degree of strength and elasticity in order to reinforce the front cloth part 2 as an inner layer to support the breast and prevent the teat from seeping through the front cloth part. Although there is no particular limitation as long as it is present, for example, a nonwoven fabric is preferable from the viewpoint of touch and thickness.

  The shape of the outer peripheral edge cloth portion 6 is a shape having a function of suppressing the shaking of the breast during exercise by surrounding the outer peripheral edge of the breast from the upper side to the sides and connecting both ends separately to the under portion 5. If there is no particular limitation. The outer peripheral edge fabric portion 6 is sewn at its upper end portion to the front fabric portion 2, and is also sewn at the connection portion with the under portion 5, and is not sewn to the front fabric portion 2 at other portions. Is preferably installed. By adopting this shape, the center of the breast with the nipple is not fixed, so it is possible to suppress the shaking of the breast without applying force to the nipple portion and its vicinity, and the feeling of pressure when worn can be reduced. . In addition, since the roundness of the breast is not crushed, a beautiful silhouette can be maintained.

  For example, the shape which comprises the other two sides of the substantially triangular shape which makes the switching part of the front cloth part 2 and the shoulder cloth part 3 a vertex and makes the under part 5 a base is mentioned. A substantially triangular shape means a triangle or a shape close thereto (including a triangular shape having a gentle curve on each side). Of the two sides of the substantially triangular shape, one side on the side portion side may be connected to the side portion, but is preferably not connected. Further, the left and right substantially triangular shapes may be connected at adjacent vertices in the under portion 5. The widths of the two sides of the substantially triangular shape need not be constant between the switching portion between the upper front cloth portion 2 and the shoulder cloth portion 3 and the lower lower portion 5. In order to suppress the shaking of the breast at the time of exercise, the front cloth portion 2 may have a function of preventing extension, and the width is preferably about 2 to 3 cm. Further, the length of the two sides of the triangle may be such a length that the outer peripheral edge fabric portion 6 is stretched when worn, and the breast is prevented from shaking by the force to shrink. That is, the length of the two sides of the triangle is preferably slightly shorter than the length of the front cloth portion 2 at the installation location, and particularly preferably about 3 to 7 mm.

  It is also possible to take a shape in which the outer peripheral edge of the breast is surrounded in an inverted U shape and both ends of the inverted U shape are connected to the under part. The side of the inverted U-shaped side may be connected to the side, but is preferably not connected. The left and right inverted U-shapes can also be connected to each other at their adjacent sides. The width of the inverted U character need not be constant. In order to suppress the shaking of the breast at the time of exercise, the front cloth portion 2 may have a function of preventing extension, and the width is preferably about 2 to 3 cm. Further, the length of the inverted U-shape may be such a length that the breast outer peripheral fabric portion 6 is in a stretched state when worn and suppresses the shaking of the breast by the force to be shrunk. That is, the length of the inverted U-shape is preferably slightly shorter than the periphery of the front cloth portion 2 at the installation location, and particularly preferably about 6 to 14 mm.

  The shape of the breast shielding part 7 is not particularly limited as long as it prevents the teat from being seen through the front cloth part. For example, the lower side is in contact with the under part, the upper side is a height that covers the nipple, and a shape that gently curves along the shape of the front cloth part 2 can be mentioned.

  The sports bra of the present invention does not directly press and fix the center of the breast where the nipple is located, but is fixed so as to surround the outer periphery of the breast. Can be suppressed, and the feeling of pressure when worn can be further reduced. In addition, since the bulge of the breast is not crushed, the breast silhouette can be kept beautiful. Furthermore, since a knitted fabric is used as a material surrounding the outer periphery of the breast instead of a rubber material having a strong pressure, it is excellent in touch when worn and has little pressure.

  Therefore, it is suitable for both girls who are developing and whose breasts are hard and tend to feel pain due to compression, and for adult women who tend to shake during exercise because their breasts are soft.
