Zusammenfassung:	A fan of the present invention includes a fan member, a motor that drives to rotate the fan member, and a rotating shaft that is connected to the fan via a vibration prevention member and transmits a turning force of the motor to the fan. The vibration prevention member is an elastic member that connects an inner cylinder made of metal included in the rotating shaft and an outer cylinder made of metal included in the fan member. At least one of an outer circumferential section of the inner cylinder and an inner circumferential section of the outer cylinder is configured in a polygonal shape when viewed from the rotating shaft direction. According to the present invention, a turning force received by the vibration prevention member acts as compression stress on an adhesion interface between a vibration prevention material and metal. Therefore, it is possible to reduce shearing stress to the adhesion interface between the vibration prevention material and the metal and reduce excessive stress due to stress concentration.
