Abstract: A fan device that can be attached to a garment body includes a fan, a drive, an operation interface, and a controller. The drive rotates the fan. The operation interface is for a user to switch drive status of the drive. The controller switches the drive status of the drive based on operation on the operation interface by the user. The operation interface includes a first switch and a second switch. The first switch is for switching an air volume of the fan between air volumes of multiple modes. The second switch is for switching a mode to a first mode in which the air volume of the fan is a first air volume which is larger than air volumes that are switched by the first switch.
