PROBLEM TO BE SOLVED: To improve a problem of working environment on handling an adhesive as a chemical substance, a difficulty of decomposition for recycling resources, and the like, and reduce vibration when operating. SOLUTION: This axial flow fan forms a recessed groove which extends to a circumferential direction around an outer surface of a bearing housing integrally formed with a venturi case, and an annular elastic member such like a hard rubber forming a circular section is attachedly fitted into the recessed groove. The outer peripheral surface of the bearing housing is loosely fitted to an inner diameter of a motor stator, and an elastic member interposed at the attachedly fitting part between the outer surface of the bearing housing and the inner diameter of the motor stator.
