DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment will be described with reference to the drawings. In the following description, when a portion of the visor 15 of the headgear 1A located on a center line CL (hereinafter simply referred to as the "center line CL in the left-right direction") that passes through the center of the headgear 1A in the left-right direction and extends in the front-to-rear direction is defined as a vertical direction that is perpendicular to the left-to-right direction, and a direction perpendicular to the left-to-right direction and the up-to-down direction is defined as a front-to-rear direction.

[0012] FIG. 1A is a side view of a headgear 1A according to an embodiment. FIG. 1B is a perspective view of the headgear 1A as viewed from above and from the front. As shown in FIGS. 1A and 1B, the headgear 1A is a baseball helmet. The headgear 1A includes a headgear main body 2 and a headgear ridge group 3A (hereinafter simply referred to as "ridge group 3A") fixed to the outer surface of the headgear main body 2.

[0013] The headgear main body 2 includes a crown 10 that covers the user's head, a visor 15 connected to the front end of the crown 10, and a pair of earmuffs 20 that cover the user's ears. Note that in Fig. 1A, only one of the pair of earmuffs 20 is visible, with the other earmuff 20 hidden by the other earmuff 20 and not visible.

[0014] The headgear main body 2 is an integrated unit consisting of the crown 10, the visor 15, and a pair of earmuffs 20. The material of the headgear main body 2 may be a thermosetting resin (for example, fiber reinforced plastic) or a thermoplastic resin (for example, ABS resin (acrylonitrile butadiene styrene resin)). A foamed resin (for example, polystyrene foam) for shock absorption may be arranged inside the crown 10 and the pair of earmuffs 20. The outer surface of the headgear main body 2 may be coated with a glossy paint.

[0015] The crown 10 includes a front crown 11 that covers the front of the user's head and is connected to the rear end of the visor 15, a rear crown 12 that covers the rear of the user's head, a pair of side crowns 13 that cover a pair of the user's sides and are connected to the upper ends of a pair of earmuffs 20, and a top crown 14 that covers the top of the user's head and is connected to the upper ends of the front crown 11, the rear crown 12, and the pair of side crowns 13. Note that in FIG. 1A, only one of the pair of side crowns 13 is visible, and the other side crown 13 is hidden by the other side crown 13 and is not visible.

[0016] The visor 15 includes an outer surface 16 that extends downward from the center of the visor 15 in the left-right direction outward and faces upward. A glossy paint is applied to the outer surface 16 except for a front end portion 18 thereof. The front end portion 18 has a protrusion that protrudes upward from the outer surface 16 of the visor 15. The front end portion 18 does not have to have the protrusion. The glossy paint may also be applied to the front end portion 18, so that the entire outer surface 16 is coated with a glossy paint.

[0017] The outer surface 16 of the visor 15 is symmetrical about the center line CL in the left-right direction when viewed from above. Therefore, hereinafter, only the left side portion of the outer surface 16 will be described unless otherwise necessary, and similar descriptions of the right side portion of the outer surface 16 will not be repeated. The front end of one side portion in the left-right direction of the outer surface 16 (in other words, the left side portion) has a curved shape that convexly extends forward and leftward when viewed from above. When viewed from the side, this curved shape extends downward and rearward from the front end of the outer surface 16 on the center line CL at a relatively steep incline (inclined relative to the horizontal), then bends, and extends downward and rearward at a gradual incline (inclined relative to the horizontal) toward the crown side portions 13. The incline of the curved shape after bending is gentler than the incline (inclined relative to the horizontal) of each of the first ridges 31 and third ridges 33 (described below) toward the crown side portions 13.

[0018] The ridge group 3A is arranged along a boundary 25 (hereinafter simply referred to as "boundary 25") between the outer surface of the crown 10 and the outer surface of the visor 15. The first ridge 31 extends from the center of the boundary 25 in the left-right direction toward the crown side head 13. The second ridge 32 extends along the front end of the outer surface 16 of the visor 15 and extends toward the crown side head 13. The third ridge 33 extends from the center of the outer surface 16 in the left-right direction between the first ridge 31 and the second ridge 32 in the front-rear direction. In FIGS. 1A and 1B, the reference numerals of the first to third ridges 31 to 33 are indicated together with the reference numerals of a ridge member 100A (described later). The same applies to FIGS. 2A and 2B (described later).

[0019] The first protrusion 31 extends along the boundary 25 from the center line CL in the left-right direction to each of the crown side heads 13. The first protrusion 31 may extend along the boundary 25 from the center line CL in the left-right direction to each of the pair of crown side heads 13, or may extend adjacent to the boundary 25 and parallel to the boundary 25. The center of the first protrusion 31 in the left-right direction is curved with a predetermined curvature so as to protrude forward (opposite the crown 10) when viewed from above. The first protrusion 31 is symmetrical with respect to the center line CL in the left-right direction when viewed from above.

[0020] The second ridge 32 extends from the center line CL in the left-right direction of the front end of the outer surface 16 of the visor 15 to each of the crown side heads 13 and the other crown side heads 13 along the front end of the outer surface 16. In FIGS. 1A and 1B , the second ridge 32 is shown adjacent to the front end 18 of the visor 15 on the rear side. However, this is not limited to this, and the front end 18 may not have a protrusion that protrudes above the outer surface 16, and the second ridge 32 may be disposed on the front end 18. One side portion in the left-right direction of the second ridge 32 (in other words, the left side portion) has a curved shape that is convex forward and leftward when viewed from above. The convex curved shape of the second ridge 32 is similar to the convex curved shape of one side portion in the left-right direction of the outer surface 16 described above, and therefore similar description will not be repeated here. The other side of the second ridges 32 in the left-right direction (in other words, the right side) is symmetrical with the one side of the second ridges 32 in the left-right direction about the center line CL when viewed from above.

[0021] The third ridges 33 extend along the left-right center line CL from the front-rear center of the outer surface 16 of the visor 15 to each of the pair of crown side heads 13 along the front-rear center of the outer surface 16. The left-right center of the third ridges 33 is curved at a predetermined curvature in a convex shape toward the front (the side opposite the crown 10) when viewed from above. The curvature of the third ridges 33 is greater than the curvature of the first ridges 31 described above. As a result, when viewed from the side, the inclination of the third ridges 33 toward one of the crown side heads 13 (with respect to the horizontal) is gentler than the inclination of the first ridges 31 toward one of the crown side heads 13 (with respect to the horizontal). The third ridges 33 are symmetrical about the left-right center line CL when viewed from above.

[0022] The end of the third protrusion streak 33 on the crown side head 13 side is located between the end of the first protrusion streak 31 on the crown side head 13 side and the end of the second protrusion streak 32 on the crown side head 13 side in the vertical direction, and is located on the same first imaginary straight line VL1 that extends in the vertical direction as the end of the first protrusion streak 31 and the end of the second protrusion streak 32.

[0023] When viewed from the side, the distance between the first ridges 31 and the third ridges 33, and the distance between the third ridges 33 and the second ridges 32, each become smaller from the center in the left-right direction of the outer surface 16 of the visor 15 toward the crown side head portions 13. When viewed from the side, the end of the first ridges 31 on the crown side head portion 13 side, the end of the third ridges 33 on the crown side head portion 13 side, and the end of the second ridges 32 on the crown side head portion 13 side are adjacent to one another in the up-down direction.

[0024] As described above, the second ridges 32 have a curved portion when viewed from the side. On the other hand, the first ridges 31 and the third ridges 33 do not have a curved portion like the second ridges 32, and are gently inclined (inclined relative to the horizontal) downward and backward toward the crown temporal portion 13 when viewed from the side.

[0025] With respect to a length region on the centerline CL of the outer surface 16 of the visor 15 in the left-right direction, the rear end of the outer surface 16 is defined as 0% and the front end of the outer surface 16 is defined as 100%. In this case, the front end 18 of the visor 15 is located in a region that is 95% or more and less than 100% of the length region. The first ridges 31 are arranged in a region that is 0% or more and 30% or less of the length region, preferably 0% or more and 5% or less. The first ridges 31 may be arranged along the boundary 25 on the outer surface of the crown 10. In this case, with respect to a length region obtained by extending the length region along the outer surface of the crown 10 in the negative direction, the first ridges 31 are arranged in a region that is -30% or more and 0% or less, preferably -10% or more and 0% or less. The second ridges 32 are arranged in a region that is 70% or more and 100% or less of the length region, preferably 90% or more and 100% or less. The third ridges 33 are disposed between the first ridges 31 and the second ridges 32 in the length region.

[0026] Fig. 2A is a cross-sectional view taken along line IIA-IIA in Fig. 1B, and Fig. 2B is a cross-sectional view taken along line IIB-IIB in Fig. 1A. As shown in Figs. 2A and 2B, the first to third ridges 31 to 33 each have an elongated adhesive layer 41 whose underside is bonded to the outer surface 16 of the visor 15, and an elongated ridge body 40 whose underside is bonded to the upper surface of the adhesive layer 41. The first to third ridges 31 to 33 have the same structure. Therefore, only the third ridge 33 will be described below, and similar descriptions of the first ridges 31 and second ridges 32 will not be repeated.

[0027] The adhesive layer 41 may be double-sided tape. Alternatively, the adhesive layer 41 may be an adhesive applied directly to the bottom surface 43 of the ridge body 40, or may be arranged in another manner on the bottom surface 43 of the ridge body 40. The width of the adhesive layer 41 may be smaller than the width of the ridge body 40. This allows, for example, when the adhesive layer 41 is double-sided tape and is manually attached to the bottom surface 43 of the ridge body 40, the adhesive layer 41 to be easily attached to the bottom surface 43 so that the adhesive layer 41 is embedded in the bottom surface 43 when the ridge body 40 is viewed from the bottom surface 43 side.

[0028] The ridge body 40 has a protruding end 42. The cross section of the ridge body 40 has a tapered shape that narrows as it moves away from the outer surface 16 of the visor 15. The apex 42a of the tapered shape is located outward in the width direction of the tapered shape from the base 43a of the tapered shape. In the state shown in FIG. 2A , the tapered shape has one oblique side 44a facing the crown 10 and another oblique side 45a facing away from the crown 10. The apex 42a is part of the protruding end 42 of the ridge body 40. The base 43a is part of the bottom surface 43 of the ridge body 40 facing the outer surface 16. The one oblique side 44a is part of one oblique surface 44 of the ridge body 40 facing the crown 10. The other oblique side 45a is part of the other oblique surface 45 of the ridge body 40 facing away from the crown 10.

[0029] As shown in FIGS. 2A and 2B , a second imaginary line VL2 is defined, passing through one end of the tapered base 43a on the vertex 42a side in the width direction and perpendicular to the base 43a. As shown in FIG. 2A , in a portion of the ridge body 40 located in the center of the visor 15 in the left-right direction, the vertex 42a is located rearward of the second imaginary line VL2. As a result, in at least a portion of the ridge body 40 of each of the second and third ridges 32 and 33 located in the center of the visor 15 in the left-right direction, one oblique side 44a is inclined to extend rearward and upward, and the other oblique side 45a is inclined to extend rearward and upward at a steeper slope than the one oblique side 44a. Furthermore, as shown in FIG. 2B , in portions of the ridge body 40 located at both ends of the visor 15 in the left-right direction, the vertex 42a is located above the second imaginary line VL2. As a result, in the portions of the ridge body 40 of each of the first to third ridges 31 to 33 located at both left and right ends of the visor 15, one oblique side 44a is inclined to extend laterally and upward, and the other oblique side 45a is inclined to extend laterally and upward at a steeper slope than the one oblique side 44a.

[0030] For example, if the headgear 1A is a baseball helmet and the outer surface 16 of the visor 15 is painted with a glossy black paint, at least the other slope 45 of the ridge body 40 (i.e., the slope 45 of the ridge body 40 facing away from the crown 10 in the state shown in FIG. 2A ) may be painted with the same glossy black paint as the outer surface 16. This allows the third ridges 33 to be placed on the outer surface 16 without looking out of place. The ridge body 40 may be made of, for example, polyvinyl chloride (PVC). This makes it easier for the adhesive layer 41 to adhere to the bottom surface 43 of the ridge body 40. The ridge body 40 may also be made of a resin such as rubber, a sponge, or other substance.

[0031] For example, the first to third ridges 31-33 may be sold separately from the headgear main body 2, and the user may arrange the first to third ridges 31-33 on the headgear 1A themselves. In this case, a guide sheet shaped to correspond to the outer surface 16 of the visor 15 and an instruction manual may be prepared together with the first to third ridges 31-33, and the first to third ridges 31-33, guide sheet, and instruction manual may be sold as a headgear ridge group attachment set. The guide sheet has a shape that corresponds to the outer surface 16. The guide sheet has an adhesive layer that is attached to the outer surface 16 and a surface layer that is laminated on the adhesive layer and to which the first to third ridges 31-33 are attached. The surface layer has lines marked on it at the locations where the first to third ridges 31-33 should be attached. This allows the user to refer to the instructions and attach the guide sheet to the outer surface 16, and then attach the first to third ridges 31 to 33 to the guide sheet along the lines, thereby allowing the user to easily arrange the ridge group 3A on the headgear 1A.

[0032] The guide sheet may have elongated holes instead of the lines at the locations on the surface where the first to third ridges 31 to 33 should be attached. This allows the user to attach the guide sheet to the outer surface 16 of the visor 15 while referring to the instructions, and then attach the first to third ridges 31 to 33 to the portions of the outer surface 16 that are exposed through the holes in the guide sheet. In this case, after attaching the first to third ridges 31 to 33 to the outer surface 16, the user may remove only the guide sheet from the outer surface 16. Alternatively, a sheet of paper with a URL written on it may be prepared instead of the instructions, and the user may attach the first to third ridges 31 to 33 to the outer surface 16 while referring to the instructions posted at the URL.

[0033] According to the configuration described above, water droplets sliding down the outer surface of the crown 10 toward the visor 15 collide with the first ridges 31 arranged along the boundary 25. As a result, the water droplets travel along the first ridges 31 and are discharged to the side. Even if the water droplets travel forward over the first ridges 31, the water droplets are slowed down by the collision with the first ridges 31 and then collide with the third ridges 33 arranged on the outer surface 16 of the visor 15 and extending toward the crown temporal region 13. As a result, the water droplets travel along the third ridges 33 and are discharged to the side without traveling forward over the third ridges 33. Here, the third ridges 33 are arranged on the outer surface 16 between the first ridges 31 and the second ridges 32 arranged along the front end of the outer surface 16 in the front-to-rear direction when viewed from above, and therefore the water droplets are discharged to the side at a position away from the front end of the visor 15. That is, even if water droplets do pass forward over the third ridges 33, they can flow sideways along the outer surface 16, reducing the possibility of them passing forward over the front end of the visor 15 and falling. As described above, water droplets are more effectively prevented from falling into the user's field of vision than in conventional art. Even if water droplets reach the front end of the outer surface 16, they are discharged sideways along the second ridges 32. Even if water droplets are not discharged sideways along any of the first through third ridges 31 through 33, they can be kept on the outer surface 16 of the visor 15 by any of the first through third ridges 31 through 33 for a predetermined period of time (for example, while the user is standing in the batter's box), thereby preventing water droplets from falling into the user's field of vision for that certain period of time.

[0034] The end of the third ridge 33 facing the crown side head 13 is located on the same first imaginary line VL1 extending in the vertical direction as the end of the first ridge 31 facing the crown side head 13 and the end of the second ridge 32 facing the crown side head 13. Therefore, water droplets discharged laterally along the third ridge 33 fall downward while absorbing water droplets discharged laterally along the first ridge 31 and the second ridge 32. This can improve drainage efficiency.

[0035] The cross section of the ridge body 40 has a tapered shape that narrows as it gets further away from the outer surface 16 of the visor 15. With this configuration, water droplets that fall directly onto the first to third ridges 31 to 33 are less likely to remain on the outer surface of the first to third ridges 31 to 33 than when the cross section of each of the first to third ridges 31 to 33 is rectangular, for example. This can improve drainage efficiency.

[0036] The apex 42a of the tapered cross section of each of the first to third ridges 31 to 33 is located outward in the width direction of the tapered shape relative to the base 43a of the tapered shape. At least in the portion of the ridge body 40 of each of the second and third ridges 32, 33 located in the center of the visor 15 in the left-right direction, the oblique sides 44a are inclined to extend rearward and upward, thereby preventing water droplets from riding forward over at least the second and third ridges 32, 33. This further prevents water droplets from falling into the user's field of vision. Furthermore, in the portion of the ridge body 40 of each of the first to third ridges 31 to 33 located at both ends of the visor 15 in the left-right direction, the oblique sides 44a are inclined to extend sideways and upward, preventing water droplets from falling from the corresponding portion of each of the first to third ridges 31 to 33 and allowing them to travel down the portion and be discharged to the end of each of the first to third ridges 31 to 33 near the crown temporal head 13.

[0037] As described above, the first ridges 31 and the third ridges 33 are each inclined gradually downward and rearward toward the crown temporal region 13 at a steeper gradient than the second ridges 32 when viewed from the side, allowing water droplets to be smoothly drained to the side along the first ridges 31 and the third ridges 33. This can improve drainage efficiency.

[0038] The technology of the present disclosure is not limited to the above-described configuration. Fig. 2C is a cross-sectional view of a modified headgear 1B corresponding to Fig. 2A. Note that headgear 1B has the same structure as headgear 1A, except that it has ridge group 3B instead of ridge group 3A. Therefore, the same or similar parts are given the same reference numerals, and similar descriptions will not be repeated.

[0039] As shown in Fig. 2C, the ridge group 3B arranged on the headgear 1B has a base portion 46 having a shape corresponding to the outer surface 16 of the visor 15, an adhesive layer 41 bonded to the underside of the base portion 46 and having a shape corresponding to the base portion 46, and first to third ridges 31 to 33 protruding from the upper surface of the base portion 46. The first to third ridges 31 to 33 each include a ridge body 40. The ridge body 40 has a structure similar to that of the ridge body 40 in the ridge group 3A described above, except that it is integral with the base portion 46. Therefore, similar descriptions will not be repeated here.

[0040] According to the above configuration, by simply adhering one adhesive layer 41 to the outer surface 16 of the visor 15, all of the ridge group 3B (in other words, all of the first to third ridges 31 to 33) can be arranged on the outer surface 16. Therefore, the ridge group 3B can be easily arranged on the outer surface 16.

[0041] In the above embodiment, a case has been described in which the apex 42a of the tapered shape of the cross section of the ridge body 40 is located outward in the width direction of the tapered shape from the base 43a of the tapered shape, and one oblique side 44a and the other oblique side 45a are each inclined to extend rearward and upward at a portion of the third ridge 33 located in the center in the left-right direction of the outer surface 16 of the visor 15, and are inclined to extend sideways and upward at portions of the third ridge 33 located at both ends in the left-right direction of the outer surface 16. However, this is not limiting, and for example, one oblique side 44a and the other oblique side 45a may each be inclined to extend forward and upward at a portion of the third ridge 33 located in the center in the left-right direction of the outer surface 16, and be inclined to extend sideways and downward at portions of the third ridge 33 located at both ends in the left-right direction of the outer surface 16. With this configuration, the slope 44 of the ridge body 40 facing the crown 10 is larger than the slope 44 of the headgear 1A, making it easier for water droplets to fall directly onto the slope 44. Therefore, water droplets that fall directly onto the third ridges 33 are more likely to run down the slope 44 and be discharged to the side, further preventing water droplets from falling into the user's field of vision. Note that by giving the first ridges 31 and second ridges 32 the same structure as the third ridges 33, the same effect as the third ridges 33 can be achieved.

[0042] Alternatively, for example, the apex 42a of the tapered cross section of the ridge body 40 may be located inward in the width direction of the tapered shape relative to both ends of the base 43a of the tapered shape, and one oblique side 44a and the other oblique side 45a may be inclined at the same gradient. In such a case, for example, the other inclined surface 45 of the ridge body 40 facing away from the crown 10 may be painted with a black glossy paint similar to the outer surface 16 of the visor 15, and the one inclined surface 44 of the ridge body 40 facing the crown 10 may be painted with a yellow matte paint different from the outer surface 16. In this way, if the headgear 1A is a baseball helmet, the third ridge 33 can be arranged on the outer surface 16 with the other inclined surface 45 facing away from the crown 10, resulting in a natural appearance. On the other hand, if the headgear 1A is a construction site helmet, the third ridge 33 can be arranged on the outer surface 16 with the one inclined surface 44 facing away from the crown 10, resulting in a natural appearance. That is, one third ridge 33 can be arranged on two types of headgear 1A without creating a sense of incongruity. Note that by making the first ridge 31 and the second ridge 32 have the same structure as the third ridge 33, the same effect as the third ridge 33 can be achieved.

[0043] In the above embodiment, the first to third ridges 31 to 33 have the same shape. However, this is not limiting, and the first to third ridges 31 to 33 may have different shapes. In such a case, at least one of the first to third ridges 31 to 33 may include a ridge body 40 having a protruding end.

[0044] In the above embodiment, the left-right central portion of the third ridge 33 is curved at a predetermined curvature in a convex shape toward the front (the side opposite the crown 10) when viewed from above. However, this is not limited to this, and the left-right central portion of the third ridge 33 may extend linearly in the left-right direction when viewed from above. This prevents water droplets from accumulating in the left-right central portion of the third ridge 33. This can improve drainage efficiency.

[0045] In the above embodiment, the first to third ridges 31 to 33 are arranged on the headgear main body 2 so as to be symmetrical about the center line CL in the left-right direction when viewed from above. However, this is not limited to this, and at least one of the first to third ridges 31 to 33 may be arranged on the headgear main body 2 so as not to be symmetrical about the center line CL in the left-right direction when viewed from above. For example, if the headgear 1A is a baseball helmet for a right-handed batter, the arrangement of the first to third ridges 31 to 33 may be adjusted appropriately so that water droplets are less likely to fall from the front end of the outer surface 16 of the visor 15, particularly from the center and right portions in the left-right direction. Similarly, if the headgear 1A is a baseball helmet for a left-handed batter, the arrangement of the first to third ridges 31 to 33 may be adjusted appropriately so that water droplets are less likely to fall from the front end of the outer surface 16, particularly from the center and right portions in the left-right direction.

[0046] In the above embodiment, the case has been described where each of the ridge groups 3A and 3B includes one third ridge 33 between the first ridge 31 and the second ridge 32 in the front-rear direction. However, this is not limited to this case, and the ridge group may include multiple third ridges 33 between the first ridge 31 and the second ridge 32 in the front-rear direction.

[0047] In the above embodiment, the first ridges 31 and the third ridges 33 are curved with different curvatures when viewed from above. However, this is not limiting, and the first ridges 31 and the third ridges 33 may be curved with the same curvature when viewed from above.

[0048] In the above embodiment, a case has been described in which nothing is placed in the space defined by the outer surface 16 of the visor 15, the first ridges 31, and the third ridges 33, and the space defined by the outer surface 16, the second ridges 32, and the third ridges 33. However, this is not limiting, and a water-absorbent substance (such as a sponge) may be placed to fill these spaces. This allows water droplets to be absorbed by the substance, further preventing water droplets from falling into the user's field of vision.

[0049] In the above embodiment, the headgear 1A, 1B are baseball helmets each equipped with a pair of earmuffs 20. However, the present invention is not limited to this, and the headgear 1A, 1B may each be a baseball helmet without a pair of earmuffs 20, or may each be a baseball helmet equipped with only one earmuff on either the left or right side. Alternatively, the headgear 1A, 1B may each be a helmet other than a baseball helmet, a cap, or other headgear.

[0050] In the above embodiment, a case has been described in which glossy paint is applied to the outer surface of the headgear main body 2. However, this is not limited to this case, and the outer surface of the headgear main body 2 may not be painted, or may be subjected to a matte surface treatment.

[0051] In the above embodiment, the ridge group 3 is sold separately from the headwear main body 2. However, this is not limited to this case, and the headwear 1A including the ridge group 3 may be sold with the ridge group 3 already arranged on the headwear main body 2. In this case, for example, the ridge group 3 and the headwear main body 2 may be integrated.

[0052] In the above embodiment, a headgear ridge group 3 including first to third ridges 31 to 33 is disposed on the headgear main body 2. However, this is not limited to this case. A headgear ridge member 100A having a structure similar to that of the first to third ridges 31 to 33 may be disposed on the headgear main body 2 in the same manner as the first to third ridges 31 to 33. That is, the ridge member 100A may be each of the first to third ridges 31 to 33 shown in FIGS. 1A to 2B. The ridge member 100A includes an elongated ridge body 40 having a bottom surface 43 and a protruding end 42 opposite the bottom surface 43, and an adhesive layer 41 provided on the bottom surface 43 of the ridge body 40 for attachment to the outer surface of the headgear 1A (the outer surface 16 of the visor 15 of the headgear main body 2). The ridge body 40 has a tapered cross section that narrows toward the protruding end 42. An apex 42a of the tapered shape is located outward from a base 43a of the tapered shape in the width direction of the tapered shape (hereinafter simply referred to as "width direction").

[0053] FIG. 3A is a front view of a protrusion member 100B according to a modified example. FIG. 3B is a cross-sectional view taken along line IIIB-IIIB in FIG. 3A. FIG. 3C is a cross-sectional view taken along line IIIC-IIIC in FIG. 3A. As shown in FIGS. 3A to 3C, in the protrusion member 100B, the outer angle α formed by the tapered oblique sides 44a, 45a of the protrusion main body 40, which are on the same side as the vertex 42a in the width direction with respect to the base 43a, and the third imaginary line VL3 extending from the base 43a, varies in the length direction of the protrusion main body 40 (hereinafter simply referred to as the "length direction"). With this structure, by defining the outer angle α according to the structure of the headgear main body 2 in which the protrusion member 100B is disposed, water droplets on the outer surface of the headgear main body 2 can be smoothly and appropriately discharged to the side along the protrusion member 100B.

[0054] 3A to 3C, the outer angle α may decrease from the center of the protrusion member 100B in the longitudinal direction toward each of the two ends. As a result, for example, by arranging the protrusion member 100B on the outer surface 16 of the visor 15 in the same manner as the third protrusion 33 described above, the space defined by the slope 44 of the protrusion member 100B and the outer surface 16 of the visor 15 becomes smaller from the center in the left-right direction of the visor 15 toward the crown temporal region 13. Therefore, water droplets that slide down the outer surface 16 of the visor 15 and hit the protrusion member 100B can be smoothly discharged sideways along the protrusion member 100B due to capillary action.

[0055] Alternatively, for example, if the headgear main body 2 is a construction site helmet, the protrusion member 100B may be disposed on the outer surface 16 of the visor 15 so that, when viewed from above, a central portion of the protrusion member 100B in the longitudinal direction protrudes forward at a portion of the outer surface 16 of the visor 15 corresponding to a chest pocket of clothing worn by the worker with the worker's head facing forward, and the outer angle α may decrease from the portion of the protrusion member 100B protruding forward as viewed from above toward each of the longitudinal ends. This reduces the space defined by the slope 44 of the protrusion member 100B and the outer surface 16 of the visor 15 from the portion of the visor 15 corresponding to the chest pocket toward the crown temporal region 13. Therefore, for example, water droplets that slide down the outer surface 16 of the visor 15 and strike the portion of the protrusion member 100B corresponding to the chest pocket can be appropriately discharged sideways along the protrusion member 100B by capillary action. This makes it possible to prevent water droplets from falling onto transceivers carried in chest pockets by workers at a construction site to communicate with each other, for example.

[0056] The protrusion member 100B is not limited to the above structure. For example, the protrusion member 100B may have a structure in which a first angle as the outer angle α and a second angle as the outer angle α different from the first angle alternate along the length direction. Furthermore, the outer angle α may be a third angle (e.g., 60°) at the center of the length of the protrusion member 100B, a fourth angle (e.g., 90°) larger than the third angle at the end of the length of the protrusion member 100B, and a fifth angle (e.g., 30°) smaller than the third angle between the center and the end of the length of the protrusion member 100B. Thus, for example, by arranging the protrusion member 100B on the headgear main body 2 in the same manner as the third protrusion 33 described above, the outer angle α can be made relatively large at a portion of the front end 18 of the visor 15 corresponding to the bent portion when viewed from the side. In this case, for example, the height dimension of the tapered shape of the protrusion member 100B at the portion where the outer angle α is the third angle may be approximately 10 mm, the height dimension of the tapered shape of the protrusion member 100B at the portion where the outer angle α is the fourth angle may be approximately 6 mm, and the height dimension of the tapered shape of the protrusion member 100B at the portion where the outer angle α is the fifth angle may be approximately 2 mm. Furthermore, the outer angle α may increase toward each of the longitudinal ends of the protrusion member 100B. Thus, for example, by arranging the protrusion member 100B on the headwear main body 2 in the same manner as the third protrusion 33 described above, water droplets can be smoothly discharged from the outer surface of the headwear main body 2 using each of the longitudinal ends of the protrusion member 100B as an outlet.

[0057] In each of the protrusion members 100A and 100B, the width or height of the tapered shape may vary along the length, similar to the outer angle α. That is, in a protrusion member including the protrusion members 100A and 100B, at least one of the outer angle α, the width, and the height of the tapered shape may vary along the length. Furthermore, the protrusion members 100A and 100B may or may not be plane-symmetrical with respect to an imaginary plane that is perpendicular to the length and located at the center of the length. Furthermore, the protrusion ends and the surrounding areas of the protrusion ends of the protrusion members 100A and 100B may be treated with a water-repellent finish. This prevents water droplets that slide down the outer surface of the headwear main body 2 and hit the protrusion members 100A, 100B from going over the protrusion members 100A, 100B in the forward direction. Also, the entire protrusion main body 40 of the protrusion members 100A, 100B may be treated with a water-repellent coating. This allows water droplets on the outer surface of the headwear main body 2 to run down the protrusion members 100A, 100BB and be smoothly discharged to the side.

[0058] One or more of the protrusion members 100A and 100B may be arranged on the headgear main body 2. For example, the protrusion member 100B may be arranged on the outer surface of the headgear main body 2 in the same arrangement as the protrusion member 100A shown in FIGS. 1A to 2B. Both the protrusion members 100A and 100B may be arranged on the headgear main body 2. The protrusion members 100A and 100B may each be colored in various ways, or may have characters such as a baseball team name or a construction company name written or engraved in a line along the length of the slope 45. The protrusion members 100A and 100B may each be transferred (e.g., sold) separately from the headgear main body 2. The protrusion members 100A and 100B may not each have an adhesive layer 41. In such a case, the protrusion members 100A and 100B may each be integral with the headgear main body 2.
