Next, the effects of the present embodiment having the above-described configuration, which have not yet been described, will be mainly described. It should be noted that the aspect described in "Effect" can also be applied to the above "Configuration".

When the fan section 50 can swing in an angle range of 160 degrees or more with respect to the main body section 10, for example, the main body section 10 can be put in a breast pocket of clothes and the main body section 10 can be used. Air can be blown toward the user's face in any case of using it by placing it on a desk or the like (see FIGS. 4 and 5). When the main body part 10 is put in a breast pocket of clothes and used, the fan part 50 can be tilted so as to approach the surface 12 on the other side of the main body part 10 (see FIG. 4). On the other hand, when the main unit 10 is placed on a desk or the like and used, the fan unit 50 can be tilted so as to approach one surface 11 of the main unit 10 (see FIG. 5).

When the fan portion 50 comes closest to the surface 11 on one side of the body portion 10, the base end portion 59 of the fan portion 50 and the surface 11 on the one side of the body portion 10 form an angle of about 90 degrees, and the fan portion 50 The base end portion 59 of the fan portion 50 and the other side surface 12 of the main body portion 10 may form approximately 90 degrees when the other side surface 12 of the main body portion 10 is closest. For example, it is conceivable that the base end portion 59 of the fan portion 50 is provided so as to swing more than approximately 90 degrees with respect to the surface 11 on one side. It is necessary to lengthen the length of the slide portion 19 of the main body portion 10 . In that case, the size of the blower becomes relatively large. In this respect, the fan portion 50 can swing toward both the surface 11 on one side and the surface 12 on the other side of the body portion 10, and the body portion 10 can be used by putting it in the breast pocket of clothes and the chest of clothes. By changing the swinging direction depending on whether the body part 10 is put in a pocket or not, it is possible to blow air toward a predetermined place such as a user's face while making the size of the blower compact. become.

When the fan portion 50 can be pulled out from the main body portion 10, the fan portion 50 is pulled out from the main body portion 10 only when the fan portion 50 is tilted with respect to the main body portion 10, and the fan portion 50 is pulled out from the main body portion 10.
