The third passage member 33 is bent downward from the left-right direction X by about 90 degrees. One end of the third passage member 33 is connected to the exhaust passage 31 b of the first passage member 31 . Therefore, the inside of the third passage member 33 also constitutes an exhaust passage 33b. The other end of the third passage member 33 is connected to the exhaust port 28 on the bottom surface of the casing 21 . Therefore, the air blown out from the fan 22 passes through the exhaust passage 31 b of the first passage member 31 and the exhaust passage 33 b of the third passage member 33 and is blown out from the exhaust port 28 .
　温度調節器２４は、導管部２３を流れる空気の温度を調節する。本実施形態の温度調節器２４には、ペルチェ素子が用いられている。ペルチェ素子は、板状に形成され、一方の板面が吸熱面とされ、他方の板面が放熱面とされる。温度調節器２４は、第１通路部材３１内に配置され、給気用流路３１ａと排気用流路３１ｂとを区画する仕切板として機能している。温度調節器２４は、放熱面及び吸熱面の一方が給気用流路３１ａに面し、他方が排気用流路３１ｂに面している。吸熱面が給気用流路３１ａに面している場合、給気用流路３１ａを流れる空気は吸熱面で熱を奪われて冷却される。放熱面が給気用流路３１ａに面している場合、給気用流路３１ａを流れる空気は放熱面から放出された熱で温められる。温度調節器２４は、バッテリ２５から電力が供給される。 The temperature adjuster 24 adjusts the temperature of the air flowing through the conduit section 23. A Peltier element is used for the temperature controller 24 of this embodiment. The Peltier element is formed in a plate shape, with one plate surface serving as a heat absorption surface and the other plate surface serving as a heat dissipation surface. The temperature adjuster 24 is arranged in the first passage member 31 and functions as a partition plate that separates the air supply flow path 31a and the exhaust flow path 31b. One of the heat radiation surface and the heat absorption surface of the temperature adjuster 24 faces the air supply flow path 31a, and the other faces the exhaust flow path 31b. When the heat absorption surface faces the air supply use channel 31a, the air flowing through the air supply use channel 31a takes heat from the heat absorption surface and is cooled. When the heat dissipation surface faces the air supply use channel 31a, the air flowing through the air supply use channel 31a is warmed by the heat emitted from the heat dissipation surface. The temperature controller 24 is powered by a battery 25 .

The mounting fixture 41 is formed in a substantially T-shape when viewed from the front, and a lower fixing portion 41a is fixed to the first side plate 21c (front surface) of the casing 21, and a belt 42 is attached to an upper mounting portion 41b.
　ベルト４２は、布地、合成樹脂、ゴム等によって帯状に形成され、両端部が取付具４１に取り付けられている。ベルト４２には、図示しないバックル等が設けられ、使用者Ｍへの着脱を容易に行えるようになっている。ベルト４２は、使用者Ｍが着用しているズボンに取り付けられたベルトが代用されてもよい。この場合、取付具４１にはベルトに引っ掛けるフックが設けられる。 The belt 42 is formed in a belt shape from fabric, synthetic resin, rubber, or the like, and both ends are attached to the fixtures 41 . The belt 42 is provided with a buckle (not shown) and the like so that it can be easily attached to and detached from the user M. A belt attached to the pants worn by the user M may be substituted for the belt 42 . In this case, the fixture 41 is provided with a hook for hooking on the belt.
　図６に示すように、送風ユニット１０のケーシング２１は、厳密な直方体形状ではなく、上面視において使用者Ｍの身体（臀部Ｍ１）の形状に沿うように若干湾曲している。そのため、ケーシング２１を使用者Ｍの身体にフィットさせることができる。ケーシング２１は、少なくとも使用者Ｍの身体に近い第１側板２１ｃが、身体の形状に沿うように湾曲していればよい。 As shown in FIG. 6, the casing 21 of the blower unit 10 does not have a strict rectangular parallelepiped shape, but is slightly curved along the shape of the user's M body (buttocks M1) when viewed from above. Therefore, the casing 21 can be fitted to the user M's body. As for the casing 21, at least the first side plate 21c close to the body of the user M should be curved so as to follow the shape of the body.
　図３、図５、及び図７に示すように、給気ノズル１３は、筒形状に形成されている。給気ノズル１３は、ケーシング２１の上面に形成された給気口２７に取り付けられている。給気ノズル１３は、ケーシング２１から上方へ向けて延びている。給気ノズル１３は、使用者Ｍが着用している上着１００の裾から内部に挿入される。 　As shown in Figures 3, 5, and 7, the air supply nozzle 13 is formed in a cylindrical shape. The air supply nozzle 13 is attached to an air supply port 27 formed on the upper surface of the casing 21 . The air supply nozzle 13 extends upward from the casing 21 . The air supply nozzle 13 is inserted inside from the hem of the jacket 100 worn by the user M.
　給気ノズル１３は、前後方向Ｙの長さよりも左右方向Ｘの長さが大きい扁平形状に形成されている。これにより、使用者Ｍの上着１００の裾から内側に給気ノズル１３を挿入しやすくすることができる。給気ノズル１３の左右方向Ｘの長さは、下部側よりも上部側の方がやや大きい。給気ノズル１３は、ケーシング２１の給気口２７に着脱可能に構成されていてもよい。給気ノズル１３は、形状が異なる他の給気ノズルに交換可能であってもよい。 The air supply nozzle 13 is formed in a flat shape whose length in the left-right direction X is greater than the length in the front-rear direction Y. As a result, the air supply nozzle 13 can be easily inserted from the hem of the jacket 100 of the user M to the inside. The length of the air supply nozzle 13 in the left-right direction X is slightly larger on the upper side than on the lower side. The air supply nozzle 13 may be detachably attached to the air supply port 27 of the casing 21 . The air supply nozzle 13 may be replaceable with another air supply nozzle having a different shape.
　図７に示すように、保持部材１２の取付具４１は、上下方向の途中で略Ｚ字状に折り曲げられており、ケーシング２１に固定される固定部４１ａよりもベルト４２が取り付けられる取付部４１ｂの方がやや前側（使用者Ｍの身体に近い側）に位置している。これにより、使用者Ｍの腰にベルト４２を装着し、臀部Ｍ１の近傍にケーシング２１を位置づけたとき、ケーシング２１が臀部Ｍ１に沿って前後方向Ｙに傾きにくくなっている。より詳しく説明すると、変形例に係る送風ユニットを示す図１０のように、取付具４１が直線状に形成されていると、ケーシング２１が臀部Ｍ１に沿って前傾姿勢となる。そのため、給気ノズル１３の上端が使用者Ｍの背中に向けられ、背中に風を直接的に吹き付ける可能性が高くなり、身体を冷やしすぎたり温めすぎたりする虞がある。本実施形態の保持部材１２の取付具４１は、上下方向の途中で折り曲げられているので、このような不都合を解消することができる。 As shown in FIG. 7, the attachment 41 of the holding member 12 is bent in a substantially Z-shape in the middle of the vertical direction, and the attachment portion 41b to which the belt 42 is attached is closer than the fixing portion 41a fixed to the casing 21. is located slightly forward (the side closer to the body of the user M). As a result, when the belt 42 is worn around the waist of the user M and the casing 21 is positioned near the buttocks M1, the casing 21 is less likely to tilt in the front-rear direction Y along the buttocks M1. More specifically, as shown in FIG. 10 showing the blower unit according to the modified example, if the fixture 41 is linearly formed, the casing 21 is tilted forward along the buttocks M1. Therefore, the upper end of the air supply nozzle 13 is directed toward the back of the user M, and there is a high possibility that the wind blows directly on the back of the user M, which may overheat or cool the body. Since the fixture 41 of the holding member 12 of this embodiment is bent midway in the vertical direction, such inconvenience can be eliminated.
　図７に示すように、給気ノズル１３は、上下方向Ｚの途中で略Ｚ字状に曲げられている。これにより、給気ノズル１３は、ケーシング２１に取り付けられる下部よりも上着１００内に挿入される上部の方がやや前側に位置している。上述のように取付具４１は、上部（取付部）４１ｂよりも下部（固定部）４１ａの方が身体から離れるため、仮に給気ノズル１３が上下方向に直線状に形成されていたとすると、給気ノズル１３を上着１００の内側に挿入し難くなる。本実施形態では、給気ノズル１３の上部が下部よりも前側に位置していることで、上着１００の内側に挿入しやすくなっている。 As shown in FIG. 7, the air supply nozzle 13 is bent in a substantially Z shape in the middle of the vertical direction Z. As a result, the upper portion of the air supply nozzle 13 that is inserted into the jacket 100 is located slightly forward of the lower portion that is attached to the casing 21 . As described above, since the lower portion (fixed portion) 41a of the attachment 41 is farther from the body than the upper portion (attachment portion) 41b, if the air supply nozzle 13 were formed in a straight line in the vertical direction, the air supply nozzle 13 would not be able to supply air. It becomes difficult to insert the air nozzle 13 inside the jacket 100 . In the present embodiment, the upper portion of the air supply nozzle 13 is positioned more forward than the lower portion, so that it can be easily inserted inside the jacket 100 .
　図８は、送風ユニットを装着し椅子に座った使用者を横から見た図である。
　送風ユニット１０のユニット本体１１は、使用者Ｍの臀部Ｍ１の近傍に配置されているので、使用者Ｍが椅子１０１に座ったとき、送風ユニット１０は椅子１０１の座面１０２上に載置されるか又は座面１０２よりも若干浮き上がった状態となる。そのため、使用者は、送風ユニット１０がほとんど邪魔になることなく椅子１０１に座ることができる。 FIG. 8 is a side view of a user wearing a blower unit and sitting on a chair.
Since the unit body 11 of the blower unit 10 is arranged near the buttocks M1 of the user M, when the user M sits on the chair 101, the blower unit 10 is placed on the seat surface 102 of the chair 101. or slightly raised from the seat surface 102. Therefore, the user can sit on the chair 101 without the blower unit 10 being an obstacle.

　送風ユニット１０のユニット本体１１は、使用者Ｍの身体の正面に位置づけられてもよいし、側面に位置づけられてもよい。温度調節器２４は、空気の冷却及び加熱の一方のみを行うものであってもよい。導管部２３において、第１通路部材３１は前後に流路が区画されていたが、上下に流路が区画されていてもよい。この場合、給気口２７と排気口２８との関係から、上側に給気用流路３１ａ、下側に排気用流路３１ｂが形成されることが好ましい。 The unit body 11 of the blower unit 10 may be positioned in front of the body of the user M, or may be positioned on the side. The temperature controller 24 may be one that either cools or heats the air. In the conduit portion 23, the first passage member 31 has the flow paths separated in the front and rear, but the flow paths may be separated in the upper and lower directions. In this case, considering the relationship between the air supply port 27 and the exhaust port 28, it is preferable that the air supply channel 31a is formed on the upper side and the exhaust channel 31b is formed on the lower side.
