The wearable fan D1 as described above has the following technical features and effects (1) to (7).

(1) Technical Features and Effects The first fan 200a is attached to and supported by the first attachment hole 102a of the first support portion 114a. Since the first support portion 114a extends in an oblique direction including components in the X direction and the Z′ direction, at least part of the air blown by the first fan 200a supported by the first support portion 114a is directed toward the first portion 111 a of the upper portion 111 of the bag portion 110 . Therefore, the air can be blown to at least one first exhaust port 101a of the first portion 111a of the upper portion 111 by driving the first fan 200a. Since the first part 111a of the upper part 111 is arranged in the vicinity of at least one of the first lateral part Ha and the first lateral part Fa of the waist H in the worn state, at least one first exhaust of the first part 111a Air discharged from the mouth 101a flows from between at least one of the first lateral portion Ha and the first lateral portion Fa of the waist H and the back body of the upper garment to at least one of the first lateral portion Ha and the first lateral portion Fa of the waist H. Air is blown in one direction. The blowing direction Wa of a part of the air blown by the first fan 200a supported by the first support portion 114a (all the air blown) is the first portion 111a of the upper portion 111 of the bag portion 110. and the blowing direction Wa of another part of all the air is directed to the X-direction side of the third part 111c of the upper part 111 of the bag part 110, the first By driving the fan 200a, air can be blown not only to at least one first exhaust port 101a of the first portion 111a of the upper portion 111, but also to at least one third exhaust port 101c of the third portion 111c. Since the third part 111c is arranged near the central part Hc of the waist H in the worn state, the air discharged from at least one third exhaust port 101c of the third part 111c is discharged from the central part of the waist H. Air is blown to the central portion Hc of the waist H from between Hc and the back body of the jacket.

(2) Technical Features and Effects When the second support portion 114b and the second mounting hole 102b are provided, the second fan 200b is mounted and supported in the second mounting hole 102b of the second support portion 114b. there is Since the second support portion 114b extends in an oblique direction including components in the X' direction and the Z' direction, at least part of the air blown by the second fan 200b supported by the second support portion 114b is directed to the second portion 111 b of the upper portion 111 of the bag portion 110 . Therefore, the air can be blown to at least one second exhaust port 101b of the second portion 111b of the upper portion 111 by driving the second fan 200b. Since the second portion 111b of the upper portion 111 is arranged in the vicinity of at least one of the second lateral portion Hb and the second lateral portion Fb of the waist H in the worn state, at least one of the second portions 111b of the upper portion 111 is positioned. The air discharged from the two second exhaust ports 101b flows from between at least one of the second lateral portion Hb and the second lateral portion Fb of the waist H and the back body of the jacket to the second lateral portion Hb and the second lateral portion Hb of the waist H. Air is blown to at least one of the flanks Fb. The blowing direction Wb of part of the air blown by the second fan 200b supported by the second support portion 114b (all the air blown) is the second portion 111b of the upper portion 111 of the bag portion 110. and the blowing direction Wb of another part of all the air is directed to the X′ direction side of the third part 111c of the upper part 111 of the bag part 110. By driving the two fans 200b, air can be blown not only to at least one second exhaust port 101b of the second portion 111b of the upper portion 111, but also to at least one third exhaust port 101c of the third portion 111c. Since the third part 111c is arranged near the central part Hc of the waist H in the worn state, the air discharged from at least one third exhaust port 101c of the third part 111c is discharged from the central part of the waist H. Air is blown to the central portion Hc of the waist H from between Hc and the back body of the jacket.

(3) Technical features and effects Even when the third supporting part, the third mounting hole, and the third fan are provided, the driving of the third fan causes at least one third exhaust port of the third part 111c. Air can be blown to 101c. A part of the blowing direction Wa of the air blown by the first fan 200a and the second fan 200b does not face the third part 111c of the upper part 111 of the bag part 110, Even if no holes are provided, the first fan 200a and the second fan 200b are driven to introduce air into the bag portion 110, thereby opening at least one third exhaust port of the third portion 111c. Air can be exhausted from 101c. Since the third part 111c is arranged near the central part Hc of the waist H in the worn state, the air discharged from at least one third exhaust port 101c of the third part 111c is discharged from the central part of the waist H. Air is blown to the central portion Hc of the waist H from between Hc and the back body of the jacket.

(4) Technical Features and Effects The first portion 111a of the upper portion 111 of the bag portion 110 extends in an oblique direction including components in the X direction and the Z′ direction in the attached state, and has at least one first exhaust port 101a. is opened in an oblique direction including components in the X direction and the Z direction, the air blown by the driving of the first fan 200a is preferably discharged from at least one first exhaust port 101a of the first portion 111a of the upper portion 111. can be discharged to

(5) Technical Features and Effects The second portion 111b of the upper portion 111 of the bag portion 110 extends in an oblique direction including components in the X′ direction and the Z′ direction and has at least one second exhaust gas. When the port 101b is open in an oblique direction including components in the X' direction and the Z direction, the air blown by the driving of the second fan 200b is discharged through at least one second exhaust port of the second portion 111b of the upper portion 111. 101b can be suitably discharged.

(6) Technical features and effects When at least one anti-adsorption member 300 is provided, the at least one anti-adsorption member 300 contacts the back body of the user's upper garment when worn, thereby It becomes difficult for the lower end of the body to be placed in the vicinity of at least one fan 200 exposed from the bottom side 114 of the bag part 110 . Therefore, it is possible to prevent the back body of the user's upper garment from being sucked by the at least one fan 200 due to the suction by the at least one fan 200 .

(7) Technical features and effects When at least one locking part 400 is provided, the at least one locking part 400 is hooked on the back body of the user's jacket when worn, thereby The lower end of the body is not located near the at least one fan 200 exposed from the bottom side 114 of the bag portion 110 . Therefore, it is possible to prevent the back body of the user's upper garment from being sucked by the at least one fan 200 due to the suction by the at least one fan 200 .

Note that the wearable fan D1 can be modified in design as shown below and in FIG. 3B. FIG. 3B shows a second design modification example of the wearable fan D1 of the first embodiment. The wearable fan according to the second design modification is denoted by reference numeral "D1'" in order to distinguish it from the wearable fan D1 according to the first embodiment and its design modification.
