[Figure 3] 1 shows a pattern of the sleeves of the work jacket according to the first embodiment. [Figure 4] 10 shows a pattern of the sleeves of a work jacket according to a second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, in which: FIG.

[0010] (Embodiment 1) <Work jacket composition> FIG. 1 is a schematic front view of a work jacket 100 according to the first embodiment. FIG. 2 is a schematic plan view of the work jacket 100 according to the first embodiment. In FIG. 2, the work jacket 100 is placed so that the opening formed by the first opening H1 in the collar 13 is horizontal to a plane such as the floor or the ground. FIG. 2 is a plan view of the work jacket 100 as viewed perpendicular to the plane. In FIG. 2, the sleeves 2 are arranged on the plane to prevent wrinkles from forming in the sleeves 2. FIG. 2 also shows a sleeve 2L covering the left arm of a worker. Note that "arranging the sleeves 2 on a plane to prevent wrinkles from forming in the sleeves 2" refers to a state in which the sleeves 2 are placed on the plane to minimize wrinkles in the sleeves 2, and also includes the case in which wrinkles inevitably occur when the sleeves 2 are placed on a plane due to the three-dimensional shape of the sleeves 2.

[0011] The work jacket 100 is a jacket worn by workers working at construction sites, factories, etc., and mainly comprises a body portion 1 and sleeve portions 2. When a worker wears the work jacket 100, the body portion 1 covers the worker's upper body. When a worker wears the work jacket 100, the sleeve portions 2 cover the worker's arms. The sleeve portions 2 are configured as a pair and include a first sleeve portion 2R and a second sleeve portion 2L. When a worker wears the work jacket 100, the sleeve portion 2R covers the worker's right arm. When a worker wears the work jacket 100, the sleeve portion 2L covers the worker's left arm.

[0012] As shown in FIG. 1, the body portion 1 includes a front body portion 11, a back body portion 12, and a collar portion 13. The back body portion 12 is connected to the front body portion 11 by being sewn thereto. As shown in FIG. 2, the collar portion 13 is connected integrally to the front body portion 11. An internal space V for accommodating the upper body of a worker is formed in the body portion 1. In other words, the internal space V for accommodating the upper body of the worker is formed by the front body portion 11 and the back body portion 12. A third opening H3 is formed in an area of ​​the body portion 1 located on the opposite side from the collar portion 13.

[0013] The direction in which the front body portion 11 is arranged as viewed from the back body portion 12 is the X direction as shown in FIG. 1. The direction in which the first opening H1 is arranged as viewed from the third opening H3 is the Z direction. The Z direction is perpendicular to the X direction. The direction perpendicular to the X and Z directions is the Y direction. The sleeve portion 2R is located opposite the sleeve portion 2L in the Y direction. The body portion 1 is sandwiched between the pair of sleeve portions 2R and 2L in the Y direction.

[0014] As shown in FIG. 1, a portion of the front body 11 is connected to a portion of the back body 12 via an underarm sewn line SL3R. A portion of the front body 11 is connected to a portion of the back body 12 via an underarm sewn line SL3L. In the Y direction, the underarm sewn line SL3R is located opposite the underarm sewn line SL3L. The underarm sewn line SL3R extends in the Z direction from the sleeve 2R toward the third opening H3. The underarm sewn line SL3L extends in the Z direction from the sleeve 2L toward the third opening H3.

[0015] 1, the collar 13 extends along the Z direction. The collar 13 covers the neck of the wearer. Therefore, the collar 13 may have a circular shape.

[0016] A first opening H1 and a third opening H3 are provided in the body portion 1. Each of the first opening H1 and the third opening H3 is open so as to communicate with an internal space V formed by the front body portion 11 and the back body portion 12.

[0017] 1 and 2, a first opening H1 is provided in the collar 13. The first opening H1 is open so as to communicate with the internal space V in which the upper body of the worker is accommodated. As shown in FIG. 2, the shape of the first opening H1 is circular in a plan view.

[0018] The third opening H3 is located opposite the first opening H1 in the Z direction. That is, the third opening H3 is positioned to cover the waist of the worker when the worker wears the work jacket 100. When viewed from the bottom in the Z direction, the third opening H3 has a circular shape.

[0019] As shown in FIG. 1 , the front body portion 11 includes a chest covering portion 11a, an abdominal covering portion 11b, and a pair of shoulder covering portions 11c. When a worker wears the work jacket 100, the front body portion 11 covers the chest, abdomen, and shoulders of the worker's upper body. When a worker wears the work jacket 100, the chest covering portion 11a is positioned to cover the worker's chest. When a worker wears the work jacket 100, the abdominal covering portion 11b is positioned to cover the worker's abdomen. When a worker wears the work jacket 100, the shoulder covering portions 11c are positioned to cover the worker's shoulders. In the Z direction, the chest covering portion 11a is sandwiched between the abdominal covering portion 11b and the shoulder covering portion 11c. A third opening H3 is provided at the lower end of the abdominal covering portion 11b. The sleeves 2 are connected to the chest covering portion 11a and the shoulder covering portion 11c. The collar 13 is connected to the shoulder covering portion 11c.

[0020] The front body part 11 may be provided with storage parts 11d in which any object can be stored. The number of storage parts 11d may be one or more, and may be, for example, four as shown in Fig. 1. Of the four storage parts 11d, two storage parts 11d are provided in the chest covering part 11a so as to sandwich the opening mechanism 14 in the Y direction. The remaining two storage parts 11d are provided in the abdomen covering part 11b so as to sandwich the opening mechanism 14 in the Y direction.

[0021] The body portion 1 may include an opening mechanism 14. The opening mechanism 14 is a mechanism that can separate or connect the left and right regions of the front body portion 11 by an operator's operation. The opening mechanism 14 may be formed, for example, by a zipper. The opening mechanism 14 is provided along the Z direction so as to be continuous with the first opening H1 and the third opening H3.

[0022] The pair of sleeves 2R, 2L are arranged to sandwich the body 1 in the Y direction. The pair of sleeves 2R, 2L are sewn to the body 1 so as to form an internal space for accommodating the worker's arms. The internal space for accommodating the worker's arms is connected to internal space V for accommodating the worker's upper body.

[0023] The sleeve portion 2 includes a first sleeve portion 21 and a second sleeve portion 22. When a worker wears the work jacket 100, the first sleeve portion 21 is positioned to cover the worker's upper arm. When a worker wears the work jacket 100, the second sleeve portion 22 is positioned to cover the worker's forearm. The first sleeve portion 21 is sewn to the body portion 1 and is thereby continuous with the body portion 1. Specifically, as shown in FIG. 2 , one end 21a of the first sleeve portion 21 is connected to the body portion 1 in the direction A1 in which the first sleeve portion 21 extends.

[0024] On the other hand, in the direction A2 in which the second sleeve portion 22 extends, one end 22a of the second sleeve portion 22 is continuous with the other end 21b of the first sleeve portion 21. The other end 21b of the first sleeve portion 21 is located opposite the one end 21a in the direction A1 in which the first sleeve portion 21 extends.

[0025] A second opening H2 is provided at the other end 22b of the second sleeve portion 22. The other end 22b of the second sleeve portion 22 is located opposite the one end 22a in the direction A2 in which the second sleeve portion 22 extends. The second opening H2 is open to communicate with the internal space in which the worker's arms are accommodated. When viewed from the direction A2 in which the second sleeve portion 22 extends, the second opening H2 has a circular shape. When the worker wears the work jacket 100, the second opening H2 is positioned to cover the worker's wrists. In other words, when the worker wears the work jacket 100, the worker's hands are exposed through the second opening H2.

[0026] 1 and 2, work jacket 100 according to this embodiment is characterized in that direction A1 in which first sleeve portion 21 extends is different from direction A2 in which second sleeve portion 22 extends. Because second sleeve portion 22 is bent relative to first sleeve portion 21, tension in sleeve portions 2R, 2L is reduced when the worker performs work that requires bending their arms.

[0027] The configuration of the sleeve portion 2L will be described below. As shown in FIG. 2, in a plan view of the first opening H1, the direction in which the front body portion 11 is disposed as viewed from the first opening H1 is the x-direction. The direction in which the back body portion 12 is disposed as viewed from the first opening H1 is the -x-direction. In a plan view of the first opening H1, the direction perpendicular to the x-direction is the y-direction. In FIG. 2, the work jacket 100 is placed on a plane aligned with the x- and y-directions.

[0028] Note that the term "plan view" used here refers to the view when the work jacket 100 is placed so that the opening surface formed by the first opening H1 is horizontal to a plane such as the floor or ground, and the work jacket 100 is viewed from a direction perpendicular to the opening surface (Z direction). The "plan view" of the first opening H1 shown in FIG. 2 is a plan view when the sleeves 2 are placed so that they extend along the y direction to prevent wrinkles from forming in the sleeves 2. Note that the center P1 of the first opening H1 shown in FIG. 2 is the center of the width of the first opening H1 in the y direction when the first opening H1 of the collar 13 is widened as much as possible.

[0029] As shown in Fig. 2, when the sleeve portion 2L is arranged to extend along the y direction, the sleeve portion 2 includes a front outline FL, a back outline BL, and a farthest point P2. The front outline FL is an outline that continues from the front body portion 11 to the second opening H2. The back outline BL is an outline that continues from the back body portion 12 to the second opening H2.

[0030] The farthest point P2 is located at the position farthest from the first opening H1 in the y direction. As shown in Fig. 2, when the sleeve portion 2 is arranged to extend along the y direction, the second opening H2 is located at the position farthest from the body portion 1 in the direction in which the sleeve portion 2 extends. In other words, the farthest point P2 is located on the outline that defines the second opening H2.

[0031] 2, in a plan view of the first opening H1, the outline of the tip portion of the sleeve 2 that forms the second opening H2 (also referred to as the outline of the second opening H2) extends in a direction perpendicular to the direction A2 in which the second sleeve 22 extends. In this case, the farthest point P2 is located at the position where the rear outline BL and the outline of the second opening H2 intersect. In other words, when the sleeve 2 is positioned so that it extends in the y direction, the front outline FL, the rear outline BL, and the outline that forms the second opening H2 form the outline of the sleeve 2 shown in FIG. 2.

[0032] As shown in FIG. 2, when the sleeve portion 2 is arranged to extend along the y direction, the sleeve center line A of the sleeve portion 2 extends along the direction in which the sleeve portion 2 extends. Specifically, in the region where the first sleeve portion 21 is formed, the sleeve center line A of the sleeve portion 2 extends along the direction A1 in which the first sleeve portion 21 extends. In the region where the second sleeve portion 22 is formed, the sleeve center line A of the sleeve portion 2 extends along the direction A2 in which the second sleeve portion 22 extends. The sleeve center line A is located at the center between the front outline line FL and the rear outline line BL in the x direction. In other words, when viewed from the sleeve center line A, the rear outline line BL is located opposite the front outline line FL in the x direction.

[0033] The direction A1 in which the first sleeve portion 21 extends may be determined, for example, by the following method. That is, when the work jacket 100 is placed on a plane with the back body portion 12 facing the plane as shown in FIG. 1 , a shoulder fold line and an armpit fold line at the boundary between the front body portion 11 and the back body portion 12 are identified. As shown in FIG. 2 , when the first sleeve portion 21 is placed on the plane so that the shoulder fold line and the armpit fold line overlap, a line passing through the center of the first sleeve portion 21 is identified. As shown in FIG. 2 , the direction A1 in which the first sleeve portion 21 extends can be identified as a direction along a line passing through the center of the first sleeve portion 21 in a first region Q1. As shown in FIG. 2 , the first region Q1 is a region in the y direction that is 40 to 50 percent of the distance from the center P1 to the farthest point P2 of the first opening H1 in the y direction.

[0034] The direction A2 in which the second sleeve portion 22 extends may also be determined, for example, by the following method. That is, as shown in FIG. 2, when the second sleeve portion 22 is placed on a plane so that the shoulder fold line and the underarm fold line overlap and no wrinkles are generated in the first sleeve portion 21, a line passing through the center of the cuff (second opening H2) is identified. As shown in FIG. 2, the direction A2 in which the second sleeve portion 22 extends can be identified as the direction along the line passing through the center of the second sleeve portion 22 in the second region Q2. As shown in FIG. 2, the second region Q2 is a region in the y direction that is 80 to 90 percent of the distance from the center P1 to the farthest point P2 of the first opening H1 in the y direction.

[0035] The sleeve center line A is bent at the portion of the sleeve 2 that covers the worker's elbow. Specifically, the direction A2 in which the second sleeve 22 extends is inclined toward the front body 11 with respect to the direction A1 in which the first sleeve 21 extends. In other words, as shown in FIG. 2, the second sleeve 22 extends toward the front body 11 as it moves away from the first sleeve 21. The bending of the sleeve center line A reduces the pulling force exerted by the sleeve 2 when the worker bends their arm.

[0036] As shown in FIG. 2, the measurement area Q is defined as an area in the y direction that is 40 to 90 percent of the distance from the center P1 of the first opening H1 in the y direction to the farthest point P2. When a worker wears the work jacket 100, the worker's elbow is located within the measurement area Q. Therefore, in the measurement area Q, it is sufficient that the length L2 of the rear outline line BL is longer than the length L1 of the front outline line FL. In this way, the length L2 of the rear outline line BL is longer than the length L1 of the front outline line FL, resulting in more slack in the fabric at the rear outline line BL than in the fabric at the front outline line FL. As a result, tension on the portion of the sleeve portion 2L including the rear outline line BL is reduced when the worker bends their arm.

[0037] The length L2 of the rear outline line BL is the length along the rear outline line BL in the measurement area Q. The length L1 of the front outline line FL is the length along the front outline line FL in the measurement area Q. The length L2 of the rear outline line BL may be 3 cm or more longer than the length L1 of the front outline line FL, or may be 6 cm or more longer.

[0038] In the measurement region Q, the direction A1 in which the first sleeve portion 21 extends may be inclined with respect to the direction A2 in which the second sleeve portion 22 extends. Therefore, the length of the rear outline BL may be longer than the length of the front outline FL in a region in the y direction that is 40 to 100 percent of the distance from the center P1 of the first opening H1 in the y direction to the farthest point P2.

[0039] As shown in Figure 2, when the sleeve portion 2L is arranged to extend along the y direction in a plan view of the first opening H1, the inclination angle θ1 of the direction A2 in which the second sleeve portion 22 extends relative to the direction A1 in which the first sleeve portion 21 extends may be greater than or equal to 150° and less than or equal to 170°.

[0040] When a worker wears the work jacket 100, the worker's elbows are located within the measurement area Q. Therefore, as shown in Fig. 2, the rear outline BL and the front outline FL may each include a curved portion in the measurement area Q. When the rear outline BL and the front outline FL include a curved portion in the measurement area Q and the degree of curvature of the rear outline BL is greater than the degree of curvature of the front outline FL, the length L2 of the rear outline BL becomes greater than the length L1 of the front outline FL.

[0041] The "degree of curvature of the rear outline BL" referred to here is the inclination angle θ2 shown in FIG. 2. The inclination angle θ2 is the angle formed between the direction along the rear outline BL in the first region Q1 and the direction along the rear outline BL in the second region Q2. The inclination angle θ2 is an acute angle. The "degree of curvature of the front outline FL" referred to here is the inclination angle θ3 shown in FIG. 2. The inclination angle θ3 is the angle formed between the direction along the front outline FL in the first region Q1 and the direction along the front outline FL in the second region Q2. The inclination angle θ3 is an acute angle.

[0042] As shown in FIG. 2, the sleeve portion 2 may have a sewing line SL1 along the front outline FL. The sleeve portion 2L may have a sewing line SL2 along the back outline BL. Each of the sewing lines SL1 and SL2 may be a seam line. The sleeve portion 2 may be manufactured by sewing two or more pieces together.

[0043] <Sleeve pattern> FIG. 3 shows a pattern of the sleeve portion 2L of the work jacket 100 according to the first embodiment. The sleeve portion 2L may be manufactured by sewing three parts together. Specifically, as shown in FIG. 3, the sleeve portion 2 includes a center part 2C, a front part 2F, and a rear part 2B. The sleeve portion 2L shown in FIGS. 1 and 2 can be manufactured by sewing together the center part 2C, the front part 2F, and the rear part 2B.

[0044] The central part 2C includes body side edges 2Ct, a front edge 2Ca, a back edge 2Cb, and an opening edge 2Ch. The body side edges 2Ct, the front edge 2Ca, the back edge 2Cb, and the opening edge 2Ch are the outline of the central part 2C. The front part 2F includes body side edges 2Ft, a front edge 2Fa, an underarm edge 2Fc, and an opening edge 2Fh. The body side edges 2Ft, the front edge 2Fa, an underarm edge 2Fc, and the opening edge 2Fh are the outline of the front part 2F. The back part 2B includes body side edges 2Bt, a back edge 2Bb, an underarm edge 2Bc, and an opening edge 2Bh. The body side edges 2Bt, the back edge 2Bb, an underarm edge 2Bc, and the opening edge 2Bh are the outline of the back part 2B.

[0045] In the central part 2C, the front edge 2Ca is connected to the body side edge 2Ct and the opening edge 2Ch. In the front part 2F, the front edge 2Fa is connected to the body side edge 2Ft and the opening edge 2Fh. The front edges 2Ca and 2Fa correspond to the sewing line SL1 shown in Figures 1 and 2. The central part 2C and the front part 2F are connected by sewing the front edges 2Ca and 2Fa.

[0046] In the central part 2C, the rear edge 2Cb is connected to the body side edge 2Ct and the opening edge 2Ch. In the rear part 2B, the rear edge 2Bb is connected to the body side edge 2Bt and the opening edge 2Bh. The rear edges 2Cb, 2Bb correspond to the sewing line SL2 shown in FIG. 2. By sewing the rear edges 2Cb, 2Bb, the central part 2C and the rear part 2B are connected.

[0047] In the front part 2F, the sleeve underside edge 2Fc is connected to the body side edge 2Ft and the opening edge 2Fh. In the back part 2B, the sleeve underside edge 2Bc is connected to the body side edge 2Bt and the opening edge 2Bh. By sewing the sleeve underside edges 2Fc, 2Bc, a sewing line SL4 is provided under the sleeve portion 2 as shown in FIG. 1. In this way, the front part 2F and the back part 2B are connected.

[0048] As described above, the sleeve portion 2 is formed by sewing together the central part 2C, the front part 2F, and the back part 2B.

[0049] In the central part 2C, the body side edge 2Ct is connected to the front edge 2Ca and the back edge 2Cb. In the front part 2F, the body side edge 2Ft is connected to the front edge 2Fa and the underarm edge 2Fc. In the back part 2B, the body side edge 2Bt is connected to the back edge 2Bb and the underarm edge 2Bc. The body side edges 2Ct, 2Ft, 2Bt are edges that are sewn to the body portion 1. By sewing each of the body side edges 2Ct, 2Ft, 2Bt to the body portion 1, the sleeve portion 2 and the body portion 1 are connected.

[0050] In the central part 2C, the opening edge 2Ch is connected to the front edge 2Ca and the back edge 2Cb. In the front part 2F, the opening edge 2Fh is connected to the front edge 2Fa and the underarm edge 2Fc. In the back part 2B, the opening edge 2Bh is connected to the back edge 2Bb and the underarm edge 2Bc. The opening edges 2Ch, 2Fh, and 2Bh correspond to the second opening H2 shown in Figures 1 and 2. When the central part 2C, the front part 2F, and the back part 2B are sewn together, the opening edges 2Ch, 2Fh, and 2Bh form the second opening H2.

[0051] 3, the length of the rear sides 2Cb, 2Bb may be longer than the length of the front sides 2Ca, 2Fa. In this way, by sewing together the center part 2C, the front part 2F, and the rear part 2B, a sleeve portion 2L is formed in which the length L2 of the rear outline line BL is longer than the length L1 of the front outline line FL in the measurement region Q.

[0052] As shown in FIG. 3, in the front part 2F, the length of the sleeve underside edge 2Fc may be longer than the length of the front edge 2Fa. In the back part 2B, the length of the sleeve underside edge 2Bc may be longer than the length of the back edge 2Bb. In this way, by sewing together the central part 2C, the front part 2F, and the back part 2B, the length of the sleeve underside of the sleeve portion 2 becomes longer than the length of the front outline line FL and the length L of the back outline line BL. As a result, when the worker bends or stretches their arm upward, there is sufficient fabric slack in the sleeve portion 2 under the sleeve, and tension caused by the sleeve portion 2 is reduced.

[0053] 3, the sleeve center line A of the central part 2C is a line passing through the centers of the front side 2Ca and the rear side 2Cb in a direction perpendicular to the direction in which the central part 2C extends. In the central part 2C, the length of the central part 2C along the sleeve center line A may be longer than the lengths along each of the front side 2Ca and the rear side 2Cb.

[0054] As shown in Fig. 3, the body side edges 2Ct are curved. In this way, the length of the central part 2C along the sleeve center line A is longer than each of the front edge 2Ca and the back edge 2Cb.

[0055] <Action and effect> A work jacket 100 according to the present disclosure comprises a body portion 1 and sleeve portions 2. The sleeve portions 2 are connected to the body portion 1. The sleeve portions 2 include first sleeve portions 21 and second sleeve portions 22. The first sleeve portions 21 are continuous with the body portion 1. The second sleeve portions 22 are continuous with one end 21a of the first sleeve portion 21, at the other end 21b, which is located opposite the one end 21a where the first sleeve portion 21 is continuous with the body portion 1, in a direction A1 in which the first sleeve portion 21 extends. The direction A1 in which the first sleeve portion 21 extends is different from the direction A2 in which the second sleeve portion 22 extends.

[0056] In this way, the sleeve 2 bends midway (at the connection between the first sleeve 21 and the second sleeve 22). Therefore, by tilting the second sleeve 22 toward the front body 11, the length L2 of the rear outline line BL can be made longer than the length L1 of the front outline line FL. In this case, there is more slack in the fabric at the rear outline line BL than in the fabric at the front outline line FL. As a result, tension caused by the sleeve 2 at the rear outline line BL is reduced when the worker bends their arm.

[0057] According to the work jacket 100, the body portion 1 includes a front body portion 11 and a back body portion 12. The back body portion 12 is continuous with the front body portion 11. A first opening H1 is provided in the body portion 1. The first opening H1 is open to communicate with the internal space formed by the front body portion 11 and the back body portion 12. The second sleeve portion 22 is provided with a second opening H2 that is open to communicate with the internal space. In a plan view of the first opening H1, the direction in which the front body portion 11 is arranged as viewed from the first opening H1 is defined as the x-direction. The direction perpendicular to the x-direction is defined as the y-direction. In a plan view of the first opening H1, when the sleeve portion 2 is arranged to extend along the y-direction, the sleeve portion 2 includes a front outline FL, a rear outline BL, and a farthest point P2. The front outline FL is continuous from the front body portion 11 to the second opening H2. The rear outline BL continues from the back body portion 12 to the second opening H2. The farthest point P2 is located at the farthest position in the y direction from the first opening H1. In a plan view of the first opening H1, when the sleeve portion 2 is positioned to extend along the y direction, the length L2 of the rear outline BL is longer than the length L1 of the front outline FL in a region in the y direction (measurement region Q) that is 40 to 90 percent of the distance from the center P1 of the first opening H1 in the y direction to the farthest point P2.

[0058] In this way, the length L2 of the rear outline line BL is longer than the length L1 of the front outline line FL, so that the fabric at the rear outline line BL has more slack than the fabric at the front outline line FL, thereby reducing tension caused by the sleeve portion 2 at the rear outline line BL when the worker bends their arm.

[0059] According to the work jacket 100, the sleeve portion 2 is provided with a stitching line SL1 along the front outline FL.

[0060] In this way, by sewing together a plurality of parts, it is possible to form the sleeve portion 2 in which the length L2 of the rear outline BL is longer than the length L1 of the front outline FL.

[0061] According to the work jacket 100, the sleeve portion 2 is provided with a stitching line SL2 along the rear outline line BL.

[0062] In this way, by sewing together a plurality of parts, it is possible to form the sleeve portion 2 in which the length L2 of the rear outline BL is longer than the length L1 of the front outline FL.

[0063] According to the above work jacket 100, when the sleeve portion 2 is positioned to extend along the y direction in a plan view of the first opening H1, the inclination angle θ1 of the direction A2 in which the second sleeve portion 22 extends relative to the direction A1 in which the first sleeve portion 21 extends is greater than or equal to 150° and less than 170°.

[0064] In this way, the length L2 of the rear outline line BL is longer than the length L1 of the front outline line FL, so that the fabric at the rear outline line BL has more slack than the fabric at the front outline line FL, thereby reducing tension caused by the sleeve portion 2 at the rear outline line BL when the worker bends their arm.

[0065] (Embodiment 2) <Sleeve pattern> FIG. 4 shows a pattern of the sleeve portion 2 of the work jacket 100 according to the second embodiment. FIG. 4 corresponds to FIG. 3. The sleeve portion 2 shown in FIG. 4 basically has the same configuration as the sleeve portion 2 shown in FIG. 3 and can achieve the same effects, except that the sleeve portion 2 is made up of two parts. Specifically, as shown in FIG. 4, the sleeve portion 2 includes a back part 2K in which a front part 2F and a back part 2B are integrated. In other words, the sleeve portion 2 shown in FIGS. 1 and 2 can be manufactured by sewing together a center part 2C and a back part 2K.

[0066] The back part 2K includes body side edges 2Kt, a front edge 2Ka, a rear edge 2Kb, and an opening edge 2Kh. The body side edges 2Kt, the front edge 2Ka, the rear edge 2Kb, and the opening edge 2Kh are the outline of the back part 2K. In the back part 2K, the front edge 2Ka is continuous with the body side edges 2Kt and the opening edge 2Kh. The front edges 2Ca and 2Ka correspond to the sewing line SL1 shown in Figures 1 and 2. The front edges 2Ca and 2Ka are sewn together to connect the central part 2C and the back part 2K.

[0067] In the back part 2K, the rear edge 2Kb is continuous with the body side edge 2Kt and the opening edge 2Kh. The rear edges 2Cb, 2Kb correspond to the sewing line SL2 shown in Figure 2. By sewing the rear edges 2Cb, 2Kb, the central part 2C and the back part 2K are connected.

[0068] By sewing the central part 2C and the back part 2K together as described above, the sleeve parts 2L shown in FIGS. 1 and 2 are formed.

[0069] In the back part 2K, the body side edge 2Kt is connected to the front edge 2Ka and the back edge 2Kb. The body side edges 2Ct, 2Kt are edges that are sewn to the body portion 1. By sewing each of the body side edges 2Ct, 2Kt to the body portion 1, the sleeve portion 2 and the body portion 1 are connected.

[0070] In the back part 2K, the opening edge 2Kh is continuous with the front edge 2Ka and the back edge 2Kb. The opening edges 2Ch and 2Kh correspond to the second opening H2 shown in Figures 1 and 2, and when the central part 2C and the back part 2K are sewn together, the opening edges 2Ch and 2Kh form the second opening H2.

[0071] 4, the rear sides 2Cb, 2Kb may be longer than the front sides 2Ca, 2Ka. In this way, by sewing the center part 2C and the back part 2K, it is possible to form a sleeve portion 2 in which the length L2 of the rear outline line BL is longer than the length L1 of the front outline line FL in the measurement region Q.

[0072] As shown in FIG. 4, the underarm center line B is a line passing through the center between the front edge 2Ka and the rear edge 2Kb in a direction perpendicular to the extension direction of the sleeve portion 2. The length of the back part 2K along the underarm center line B may be longer than each of the front edge 2Ka and the rear edge 2Kb. In this way, by sewing the central part 2C and the rear part 2K, the length of the underarm of the sleeve portion 2 becomes longer than the length of the front outline line FL and the length L of the rear outline line BL. As a result, when the worker stretches their arm upward, the sleeve portion 2 is stretched at the underarm, and tension caused by the sleeve portion 2 is reduced.

[0073] Although the configuration of the sleeve portion 2L has been described, the sleeve portion 2R may have the same configuration as the sleeve portion 2L.

[0074] In this specification, the "sewing line" may be a line formed by sewing together fabric using thread or the like, or a line formed by joining fabric together using adhesive or the like through a bonding process.
