Description

【Technical Field】 【0001】 The present invention relates to a spacer, a fan unit, and a ware with a fan. 【Background Art】 【0002】 In recent years, a ware with a fan for cooling the body has been put into practical use and has been rapidly spreading. The ware with a fan has a fan for taking in air into the ware body attached to the ware body formed of a material with low air permeability. When the fan is operated, a large amount of air is taken into the ware body from the fan, circulates along the surface of the body of the wearer or the underwear worn under the ware body, and then is discharged to the outside from the collar part or the like of the ware body. And while the air taken into the ware body by the fan circulates along the surface of the body of the wearer or the underwear, the sweat emitted from the body is evaporated, and the body is cooled by the heat of vaporization during evaporation (see, for example, Patent Document 1). 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 International Publication No. 2005 / 063065 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 In such a ware with a fan, if the fan is exposed to the outside of the ware with a fan (the side facing the external space on the opposite side to the side facing the wearer when worn), for example, when used in rainy weather, there may occur problems such as getting wet by rain and being likely to cause a failure, or problems such as being not aesthetically pleasing as it can be seen at a glance that it is a ware with a fan. 【0005】 Therefore, one possible solution is to prevent the fans from being exposed to the outside of the fan-equipped garment by, for example, wearing another garment over the fan-equipped garment, or by making the garment itself a two-layer structure so that the part where the fans are attached is covered with a sheet-like material. 【0006】 However, if the fan is not exposed to the outside of the fan-equipped garment in this way, the air intake section located on the outside of the fan will be covered by a sheet-like material. This may hinder the intake of air into the fan, and consequently into the garment itself, potentially preventing the fan-equipped garment from performing its cooling function adequately. 【0007】 One possible solution is to provide a spacer that hooks onto the outside of the fan to secure it, thereby preventing obstruction of airflow to the fan. However, even with a spacer on the outside of the fan, there is a possibility that the spacer could detach from the fan due to external forces. While this can be made less likely by constructing the spacer from a highly rigid material, it reduces the flexibility of the spacer's material. 【0008】 The objective of this invention is to make it difficult for the spacer to detach from the fan while maintaining the freedom of choice in the spacer material. [Means for solving the problem] 【0009】 To solve the above problems, the invention described in claim 1 is: A spacer that is attached to the fan so as to cover the air intake portion of the fan, A spacer body having an opening through which the air intake portion of the fan can be inserted, and a first annular portion formed annularly around the opening, A spacer ring integrally molded with the first annular portion and screwed into the fan, It is equipped with. 【0010】 The invention described in claim 2 is a spacer described in claim 1, The spacer ring is provided with a female threaded portion on its inner circumferential surface. 【0011】 The invention described in claim 3 is a spacer described in claim 1, The spacer ring is formed from ABS resin, The spacer body is made of silicone rubber. 【0012】 The invention described in claim 4 is a spacer described in claim 3, The spacer ring has a plurality of holes, The first annular portion is provided with a plurality of protrusions that fit into the plurality of holes, respectively. 【0013】 The invention described in claim 5 is a fan unit, A spacer according to any one of claims 1 to 4, Fans, It is equipped with. 【0014】 The invention described in claim 6 is the fan unit described in claim 5, The fan comprises a flange protruding from the outer circumference and a fan ring that screws into the spacer ring.

[Modes for carrying out the invention] 【0019】 The embodiments of the present invention will be described below with reference to Figures 1 to 13. However, the technical scope of the present invention is not limited to the illustrated examples, and various modifications can be made to the embodiments described below without departing from the spirit of the invention. 【0020】 In the following explanation, we will use the wearer wearing the fan-equipped garment as a reference point, defining the direction in front of the wearer as front, the direction behind the wearer as back, the direction above the wearer as up, the direction below the wearer as down, the direction to the wearer's right as right, the direction to the wearer's left as left, the axis along the front-to-back direction as the X-axis, the axis along the left-to-right direction as the Y-axis, and the axis along the up-to-down direction as the Z-axis. Furthermore, when explaining fans or spacers, the direction is determined and explained based on how they appear when attached to the garment itself. 【0021】 [1. Configuration of the Embodiment] As shown in Figures 1 to 5, the fan-equipped garment 100 according to this embodiment comprises a garment body 1, a fan 2 for introducing air into the garment body 1, a spacer 3 for ensuring a gap between the outer fabric 11 and the lining 12 of the garment body 1, a power supply device 4 for supplying power to the fan 2, and a connecting cable 5 for connecting the power supply device 4 and the fan 2. The fan 2 takes in air into the lining 12 of the garment body 1 (the space formed between the lining 12 and the wearer's body when the fan-equipped garment 100 is worn), circulates it along the surface of the wearer's body or underwear worn beneath the garment body 1, and then discharges it from an air outlet formed in the collar or other part of the garment body 1, thereby evaporating sweat from the body and cooling the body with the heat of vaporization during evaporation. 【0022】 [(1) Main garment] The garment body 1 is the clothing portion of the fan-equipped garment 100, excluding the fan 2, spacer 3, power supply unit 4, and connecting cable 5. Furthermore, of the garment body 1, the side that faces the wearer when worn is defined as the inner surface of the garment body 1, and the side opposite to it is defined as the outer surface of the garment body 1. Furthermore, with respect to the outer fabric 11 and lining 12, the side facing the wearer when the garment body 1 is worn is the inner surface of the outer fabric 11 or lining 12, and the opposite side is the outer surface of the outer fabric 11 or lining 12. 【0023】 As shown in Figures 1 to 5, the garment body 1 is formed to have a two-layer structure comprising an outer fabric 11 placed on the outer side of the garment body 1 and a lining 12 placed on the inner side of the garment body 1. 【0024】 Furthermore, as shown in Figures 3 to 5, the lining 12 is connected to the outer fabric 11 only at the connecting portion 13 located at its upper end by a method such as sewing. Alternatively, the outer fabric 11 and the lining 12 may be made detachable by using, for example, hook-and-loop fasteners or wire fasteners at the connecting portion 13. 【0025】 As described above, the lining 12 is connected to the outer fabric 11 only at its upper end, and not at its lower end. As a result, an opening 14 is formed between the lower end of the lining 12 and the outer fabric 11, connecting the space between the outer fabric 11 and the lining 12 with the external space, as shown in Figure 5. 【0026】 [a outer fabric] The outer fabric 11 is the outermost part of the garment body 1, and as shown in Figures 1 to 5, it is made of a waterproof fabric that does not allow rainwater to pass through, and is formed in a so-called poncho shape that covers the upper body of the wearer W with a single piece of fabric without sleeves. 【0027】 As shown in Figures 1 to 5, the outer fabric 11 is equipped with a hood 111 that covers the wearer W's head, and the front of the outer fabric 11 is equipped with a first front opening / closing means 112 for opening and closing the front of the outer fabric 11 when the wearer W puts on the fan-equipped garment 100. The first front panel opening and closing mechanism 112 is formed by making both ends of the outer fabric 11, which are located in front of the wearer W when worn, detachable by providing, for example, a zipper. Note that the hood 111 is not an essential component of the fan-equipped garment 100. 【0028】 [b Lining] The lining 12 is the inner side of the garment body 1, and as shown in Figures 1 to 5, it is constructed to form a vest-type upper garment that covers the torso of the wearer W with a fabric that is either non-breathable or breathable enough to be inflated by the introduction of air by the fan 2. 【0029】 As shown in Figures 3 to 5, the lining 12 includes a second front panel opening / closing means 121, an air leakage prevention means 122, a power supply unit holding means 123, and a fan mounting hole 124. 【0030】 The second front opening / closing mechanism 121 is a means for opening and closing the front of the lining 12 when the wearer W puts on the fan-equipped garment 100, by making the lining 12 open at the front. As shown in Figures 3 and 4, the front of the vest-type lining 12 is divided into left and right halves in the center in the left-right direction, and the divided portion is made detachable by providing, for example, a zipper on both sides. 【0031】 As shown in Figures 3 to 5, the air leakage prevention means 122 is provided near the lower end of the lining 12 and is a means to prevent air inside the lining 12 from leaking out from the lower end of the lining 12 when the wearer W wears the fan-equipped garment 100. For example, it is formed by providing an elastic member such as a rubber cord near the lower end of the lining 12 so as to wrap around the wearer W's body when the second front opening and closing means 121 is connected. 【0032】 The power supply unit holding means 123 is a means for holding the power supply unit 4 in a position where power can be supplied to the fan 2 via the connecting cable 5, and as shown in Figure 4, it is formed by a pocket in which the power supply unit 4 can be housed. 【0033】 As shown in Figures 4 and 5, the fan mounting holes 124 are openings that connect the space within the lining 12 (the space formed between the lining 12 and the wearer W's body when the fan-equipped garment 100 is worn) and the space between the outer fabric 11 and the lining 12, and are formed on the back of the lining 12 at positions corresponding to the left and right sides of the wearer W's waist. The fan mounting hole 124 is formed in a circular shape with a diameter approximately the same as the diameter of the cylindrical portion 213 of the fan body 21 of the fan 2 described later (L2 in Figures 10 and 13). By attaching the fan 2 to the lining 12 such that the cylindrical portion 213 passes through the fan mounting hole 124, air in the space between the outer fabric 11 and the lining 12 of the garment body 1 can be drawn into the space within the lining 12 through the fan mounting hole 124. 【0034】 [(2) Fans] Fan 2 is a means for introducing air from the space between the outer fabric 11 and the lining 12 into the space within the lining 12 through the fan mounting hole 124, and as shown in Figure 4, the necessary power is supplied from the power supply unit 4 via the connecting cable 5. 【0035】 As shown in Figures 8 to 13, fan 2 comprises a fan body 21, a mounting ring 22, and a fan ring 23. 【0036】 [a Fan body] As shown in Figure 13, the fan body 21 is the main body of the fan 2, housing the propeller 215 that generates airflow and the motor 216 that rotates the propeller 215. 【0037】 The propeller 215 housed within the fan body 21 rotates on the front-to-back direction (X-axis) by the motor 216, thereby generating an airflow that moves from the air intake section 211 to the air outlet section 212 (from rear to front). The shape of the propeller is not particularly limited as long as it can generate an airflow that moves from the air intake section 211 to the air outlet section 212. 【0038】 As shown in Figures 8 to 13, the fan body 21 has an air intake section 211 formed on the outer surface side (rear side, the side of the space between the outer fabric 11 and the lining 12) of the lining 12 when attached to the lining 12, which is the part that takes in air when the internal propeller rotates, and an air outlet section 212 formed on the inner surface side (front side, the side of the space between the lining 12 and the wearer W's body) of the lining 12 when attached to the lining 12, which is the part that sends out air when the internal propeller rotates. 【0039】 Furthermore, the fan body 21 includes a cylindrical connecting section 213 between the air intake section 211 and the air outlet section 212, and the end of the cylindrical section 213 on the air intake section 211 side is provided with a flange 214 that protrudes in a direction substantially perpendicular to the side surface of the cylindrical section 213. 【0040】 The cylindrical portion 213 is formed in a cylindrical shape such that the outer cross-section when cut by a plane (YZ plane) perpendicular to the propeller's rotation axis (X-axis) is circular, and its diameter is formed to be approximately the same as the diameter of the fan mounting hole 124. Furthermore, the flange 214 protruding from the cylindrical portion 213 also has a circular shape when viewed from the X-axis direction. As shown in Figures 10 and 13, the diameter of the flange 214 is L1 and the diameter of the cylindrical portion 213 is L2. Furthermore, as shown in Figures 8 to 11, a projection 2131 is formed on the outer surface of the cylindrical portion 213, which fits into a recess formed on the inner surface of the mounting ring 22 (described later), and is configured so that the mounting ring 22 can be fixed to the outer surface of the cylindrical portion 213 as described later. Note that in Figures 8 to 11, only the two projections 2131 formed on the left side of the cylindrical portion 213 are shown, but a similar projection 2131 is also formed on the right side at an opposite position. 【0041】 For the material forming the fan body 21, a general resin material can be used, except for the metal part of the motor 216. 【0042】 [b Mounting ring] The mounting ring 22 is a ring-shaped member integrally formed from a resin material such as plastic. As shown in Figures 12 and 13, it is attached to cover the outer surface of the cylindrical portion 213 of the fan body 21. As will be described later, it is used to attach the fan 2 and spacer 3 to the garment body 1 by sandwiching the portion around the fan mounting hole 124 of the lining 12 of the garment body 1 between one end of the mounting ring 22 and the flange 214 of the fan body 21. 【0043】 The mounting ring 22 is formed in an elliptical shape when viewed from the direction of rotation of the propeller 215 inside the fan body 21 (X-axis direction). Furthermore, the mounting ring 22 is formed such that the length of its inner circumference is longer than the length of the outer circumference of the cylindrical portion 213 of the fan body 21, and the minor axis of its inner circumference is smaller than or equal to the diameter L2 of the cylindrical portion 213. In this case, the major axis of the inner circumference of the mounting ring 22 is larger than the diameter L2 of the cylindrical portion 213. 【0044】 Furthermore, recesses (not shown) are formed at opposing positions on the inner surface of the mounting ring 22 in the short-axis direction, which engage with protrusions 2131 formed on the outer surface of the cylindrical portion 213 of the fan body 21. 【0045】 As described above, the mounting ring 22 is formed in a ring shape that is elliptical when viewed from the X-axis direction. However, when pressure is applied to its outer surface in the major axis direction, the minor axis direction bulges outward, and the mounting ring 22 can be deformed into a perfect circle. Furthermore, when the pressure applied to the outer surface in the major axis direction is released, the mounting ring 22 returns to its original elliptical shape. By utilizing this, the elliptical mounting ring 22 is pressed from the outer surface in the direction of its major axis, causing it to bend and deform into a perfect circle. Then, the mounting ring 22 is placed over the cylindrical portion 213 so that the position of the convex portion 2131 of the cylindrical portion 213 and the position of the concave portion of the mounting ring 22 coincide. After releasing the pressure on the mounting ring 22, the mounting ring 22 can be attached to the cylindrical portion 213 of the fan body 21. Furthermore, as described later, the fan 2 and spacer 3 can be attached to the garment body 1 by sandwiching the portion of the lining 12 of the garment body 1 around the fan mounting hole 124 between one end of the mounting ring 22 and the flange 214 of the fan body 21. 【0046】 [c Fanring] The fan ring 23 is a ring-shaped member formed from a resin material such as plastic. As shown in Figures 8 and 9, it is attached to the front of the fan body 21 so as to abut against the side of the flange 214, and is used to fix the spacer 3 to the fan body 21 by screwing it onto the spacer ring 32, as will be described later. 【0047】 The fan ring 23 is formed such that its inner circumference is approximately the same as the diameter L1 of the flange 214 of the fan body 21, and its outer circumference is longer than the diameter L1 of the flange 214 of the fan body 21. The fan ring 23 is preferably strong and lightweight, and is preferably made of, for example, ABS resin, but is not limited to this. 【0048】 Furthermore, the front annular surface of the fan ring 23 has multiple recesses formed as finger rests 231, making it easier to rotate the fan ring 23 with your fingers when fixing or detaching it from the spacer ring 32. In addition, the rim (outer circumference) of the fan ring 23 has male threads 232 formed along the circumferential direction, which screw into the female threads 322 of the spacer ring 32, which will be described later. As shown in Figures 8 and 9, the front annular surface of the fan ring 23 may have not only finger rests 231, but also markings that serve as a reference for alignment when screwing it into the spacer ring 32, or arrows that indicate the direction of rotation when screwing it in. 【0049】 [(3) Spacer] Spacer 3 is a means to secure a space between the outer fabric 11 and the lining 12 and prevent the air intake portion 211 of the fan body 21 from being blocked by the outer fabric 11. As shown in Figures 11 to 13, it is attached to the fan body 21 so as to cover the air intake portion 211 of the fan body 21 of the fan 2 from the opening 3111. Note that if the fan 2 is attached to the garment body 1 and its positional relationship with the fan body 21 is fixed, then spacer 3 is considered to be attached to the fan body 21 of the fan 2. As shown in Figures 6 and 7, the spacer 3 comprises a spacer body 31 and a spacer ring 32. 【0050】 [a Spacer body] The spacer body 31 is formed with a first annular portion 311 and a second annular portion 312, a circular plate-shaped portion 313, and a plurality of connecting portions 314 that connect the first annular portion 311, the second annular portion 312, and the plate-shaped portion 313. In addition, the spacer body 31 has air intake ports 315 formed between the plurality of connecting portions 314 to allow air to be taken into the spacer 3. The spacer body 31 is integrally formed from silicone rubber. While silicone rubber is preferred as the material for the spacer body 31, it is not limited to this, and other resin materials such as plastic, particularly those with excellent strength and light weight, such as ABS resin, can also be used. 【0051】 The first annular portion 311 is a circular, annular member provided on the front side of the spacer body 31 (the side facing the wearer W when the fan-equipped garment 100 is worn), as shown in Figures 6 and 7. The shape in which an opening 3111 is formed in the center is broadly referred to as "annular." Furthermore, the inner diameter of the first annular portion 311 is L3, as shown in Figure 12. 【0052】 As shown in Figures 6 and 7 and Figures 10 to 13, the second annular portion 312 is formed in an annular shape with an outer diameter smaller than the outer diameter of the first annular portion 311, and is positioned between the first annular portion 311 and the plate-like portion 313 in the X-axis direction. 【0053】 As shown in Figures 6 and 7 and Figures 10 to 13, the plate-shaped portion 313 is a circular plate-shaped member provided on the rear side of the spacer body 31 (the side opposite to the side facing the wearer W when the fan-equipped garment 100 is worn). 【0054】 The connecting portion 314 is a member that connects the first annular portion 311, the second annular portion 312, and the plate-shaped portion 313, and as shown in Figures 6 and 7 and Figures 10 to 13, 10 of them are provided at equal intervals to connect these three members. 【0055】 As described above, multiple connecting parts 314 are provided at intervals to connect the first annular part 311, the second annular part 312, and the plate-shaped part 313. Therefore, as shown in Figures 6 to 7 and 10 to 13, an air intake 315 is formed in the space between the connecting parts 314 on the side of the spacer body 31, connecting the inside of the spacer body 31 to the outside and allowing air to enter the spacer body 31. The side surface of the spacer body 31 refers to the outer surface of the spacer body 31 other than the surface facing the wearer W and the surface formed opposite to it when the wearer W is wearing the fan-equipped garment 100 to which the spacer body 31 is attached. 【0056】 [b Spacer ring] The spacer ring 32 is a ring-shaped member formed from a resin material such as plastic, and as shown in Figure 7, it is provided so as to be integrally molded with the annular surface on the front side of the first annular portion 311. 【0057】 The spacer ring 32 is formed such that the length of its inner circumference is the same as the length of the outer circumference of the fan ring 23. This makes it possible to have the inner circumference of the spacer ring 32 and the outer circumference of the fan ring 23 in contact, as will be described later. For the same reasons as the fan ring 23, the spacer ring 32 is preferably made of, for example, ABS resin, but is not limited to this. 【0058】 Multiple holes 321 are provided on the outer circumference of the spacer ring 32. In the manufacturing process of the spacer 3, the spacer ring 32 is integrated with the spacer body 31 by fitting the convex portions 3112 formed when liquid silicone rubber, which will become the first annular portion 311 of the spacer 3, flows into the holes 321 and solidifies. In addition, the inner circumference of the spacer ring 32 is provided with a female screw portion 322 that screws into the male screw portion 232 of the fan ring 23. In this example, the case in which the spacer 3 is made of silicone rubber and the spacer ring 32 is made of a resin material such as plastic is described, but if the spacer 3 and the spacer ring 32 are made of the same material, for example ABS resin, they can be manufactured using conventional molding methods, in which case the multiple holes 321 on the outer circumference of the spacer ring 32 provided in this example are unnecessary. 【0059】 [(4) Power supply] The power supply unit 4 is a component that supplies power to the fan 2 (the motor 216 that rotates the propeller 215 located inside the fan body 21 of the fan 2). For example, it incorporates a lithium-ion battery pack with a safety protection circuit and is connected to the fan 2 via a connecting cable 5, as shown in Figure 4. The power supply unit 4 also includes a switch to turn the power supplied to the fan 2 on and off. The power supply unit 4 only needs to be capable of supplying power to the fan 2, and its specific configuration is not particularly limited. 【0060】 [(5) Connection Cable] As shown in Figure 4, the connecting cable 5 is a cable that connects the power supply unit 4 and the fan 2, and power necessary for the operation of the fan 2 is supplied from the power supply unit 4 to the fan 2 through the connecting cable 5. The connection cable 5 only needs to be capable of supplying power from the power supply unit 4 to the fan 2 via the connection cable 5, and its specific configuration is not particularly limited. 【0061】 [2. Installation Instructions] This section explains how to attach fan 2 and spacer 3 to the garment body 1. 【0062】 [(1) Attaching the spacer to the fan body] When attaching fan 2 and spacer 3 to the garment body 1, first attach spacer 3 to the fan body 21. 【0063】 Specifically, as shown in Figure 10, the spacer 3 and the fan body 21 are positioned so that the first annular portion 311 of the spacer 3 and the air intake portion 211 of the fan body 21 of the fan 2 face each other. Then, the spacer 3 is attached to the fan body 21 by screwing the fan ring 23, which is attached to the flange 214 from the front side of the fan body 21, onto the spacer ring 32 of the spacer 3. 【0064】 [(2) Attaching the spacer and fan to the garment body 1] Next, attach the fan body 21, with the spacer 3 attached as described above, to the garment body 1. 【0065】 Specifically, as shown in Figure 11, first, the fan body 21 with the spacer 3 attached is placed on the outer side (rear side) of the portion of the lining 12 of the garment body 1 where the fan mounting hole 124 is formed, and the mounting ring 22 of the fan 2 is placed on the inner side (front side) of the portion of the lining 12 of the garment body 1 where the fan mounting hole 124 is formed. 【0066】 Next, the portion of the fan body 21 that protrudes from the opening 3111 of the spacer body 31 (the air outlet portion 212 and the cylindrical portion 213) is passed through the fan mounting hole 124 in the lining 12 of the garment body 1. Then, the mounting ring 22 is passed through the cylindrical portion 213 of the fan body 21 from the inner side of the lining 12 and secured. 【0067】 As a result, the area around the fan mounting hole 124 of the lining 12 of the garment body 1 is sandwiched between the flange 214 of the fan body 21 and the mounting ring 22, and as shown in Figures 12 and 13, the spacer 3 covers the air intake portion 211 of the fan body 21 of the fan 2, and the spacer 3 is positioned on the outer surface side of the lining 12. With the spacer 3 attached to the fan body 21 of the fan 2, the fan 2 and spacer 3 can be attached to the garment body 1. 【0068】 This allows the spacer 3 to be attached to the garment body 1 so as to cover the air intake portion 211 provided on the fan body 21 of the fan 2. In this state, as shown in Figure 5, the spacer 3 is located behind the fan 2 in the space between the outer fabric 11 and the lining 12 of the garment body 1. Furthermore, even if the spacer 3 does not cover the entire air intake section 211, if any part of the spacer 3 overlaps the air intake section 211 when viewed from the air intake section 211 side (in this case, the rear) in the direction along the rotation axis of the propeller 215, this is considered to be a case where the spacer 3 covers the air intake section 211. 【0069】 With the fan 2 and spacer 3 attached to the garment body 1, when the fan 2 is activated, air in the space between the outer fabric 11 and the lining 12 of the garment body 1 is drawn into the spacer 3 from the air intake 315. The air drawn into the spacer 3 is then drawn into the fan body 21 through the opening 3111 of the first annular portion 311, from the air intake portion 211 of the fan body 21 located inside the spacer 3, and then sent out from the air discharge portion 212 to the space inside the lining 12. 【0070】 [3 Effects of the Embodiment] According to the fan-equipped garment 100 of this embodiment, the garment comprises a spacer body 31 having an opening 3111 through which the air intake portion 211 of the fan 2 can be inserted, and a first annular portion 311 formed in an annular shape around the opening 3111, and a spacer ring 32 integrally molded with the first annular portion 311, having a female screw portion 322 on its inner circumferential surface, and screwing into the fan 2. As a result, the fan 2 is screwed onto the spacer ring 32 of the spacer 3, making it difficult for the spacer 3 to detach from the fan 2 even if it is subjected to an unavoidable force from the outside. 【0071】 Furthermore, by configuring the fan 2 to screw into a spacer ring 32 that is integrally molded with the spacer body 31, rather than the spacer body 31 itself, the spacer body 31 can be made from any material. 【0072】 Furthermore, because the spacer body 31 is integrally formed from silicone rubber, it is possible to deform the entire spacer 3 when attaching the spacer 3 to the fan body 21, making it easier to attach the spacer 3 to the fan body 21. In addition, even if the spacer body 31 is subjected to impact such as pressure by the wear body 1, damage to the spacer body 31 due to such impact can be suppressed. 【0073】 Furthermore, unlike the spacer body 31, the spacer ring 32 is made of ABS resin, which ensures sufficient strength when attaching the fan 2 to the spacer 3. 【0074】 Furthermore, because the spacer body 31 is made of silicone rubber, the protrusion 3112 formed by the liquid silicone rubber that becomes the first annular portion 311 flowing into the hole 321 of the spacer ring 32 and solidifying fits into it, allowing the spacer ring 32 to be easily integrated with the spacer body 31. 【0075】 Furthermore, by having a fan ring 23 that screws into the spacer ring 32, even with a conventional fan 2 that does not have a configuration that allows it to screw into the spacer ring 32, the spacer 3 can be made less likely to come off by attaching the fan ring 23. 【0076】 Furthermore, the garment body 1 comprises an outer fabric 11 positioned on the outer side of the garment body 1 and a lining 12 positioned on the inner side of the garment body 1, with the fan 2 attached to the lining 12 and the spacer 3 positioned between the outer fabric 11 and the lining 12. This allows the outer fabric 11 to cover the outside of the fan 2, preventing rain and other elements from entering through the air intake section 211, while the spacer 3 ensures an airflow path to the air intake section 211. 【0077】 [4. Variant] In the above description of the configuration, we described a case where the garment body 1 is composed of a poncho-type outer fabric 11 and a vest-type lining 12, which are connected and integrated by a connecting part 13. However, the configuration of the garment body 1 is not limited to the above, as long as the fan 2 attached to the garment body 1 is not exposed to the outside. 【0078】 For example, the outer fabric 11 and the lining 12 may be formed as separate components, and the outer fabric 11 may be worn separately over the lining 12. 【0079】 Furthermore, the shape of the outer fabric 11 is not limited to the poncho type as described above, but is acceptable as long as it can be worn over the lining 12. Also, the shape of the lining 12 is not limited to the vest type as described above, but is acceptable as long as it can be worn inside the outer fabric 11. 【0080】 Furthermore, even if the fan-equipped garment itself is made from a single layer of fabric, similar to conventional fan-equipped garments, and an outer garment such as a raincoat is worn over it, attaching the spacer 3 as described above can prevent the air intake to the fan from being obstructed by the outer garment worn over the fan-equipped garment. 【0081】 Furthermore, although the above example illustrates a configuration in which the fan ring 23 has a male threaded portion 232 and the spacer ring 32 has a female threaded portion 322, the configuration is not limited to this. For example, the fan ring 23 may have a female thread on its inner circumference, and the spacer ring 32 may have a projection on its outer annular surface with a male thread on the projection, thereby screwing the fan ring 23 and the spacer ring 32 together. 【0082】 Furthermore, although the above example illustrates a configuration in which the fan 2 has a fan ring 23 that screws into the spacer ring 32, the configuration is not limited to this. For example, the fan 2 may not have a fan ring 23, and the flange 214 may have a male threaded portion 232 on its outer circumference that screws into the female threaded portion 322 of the spacer ring 32.
