PURPOSE:To regulate the axial center of a motor shaft at a predetermined position on transport, and to prevent deformation and eccentricity due to falling and vibration by forming structure in which a left and right regulating section, which regulates a position in the diametral direction of an air guider and in the left and right directions of the motor shaft, and a lower section regulating section positioning the direction of a lower section are connected in the vicinity of the motor shaft. CONSTITUTION:A protective device 17 for a blower is constituted in a T shape by a left and right regulating section 15 regulating a position in the left and right directions of a motor shaft 13 to the opening section 14 of an air guider 12 and a lower section regulating section 16 regulating a position in the direction of a lower section (B), and a bearing section 18 for the motor shaft 13 is mounted at an intersecting point between the left and right regulating section 15 and the lower section regulating section 16 in response to the axial center of the opening section 14 of the air guider 12. Since the protective device 17 is fitted and fixed to a pair of Z-shaped fittings 22 around the opening section 14 of the air guider 12, the axial center of the air guider 12 and the axial center of a propeller fan 11 are conformed at all times, and damage due to falling and vibration on transport is prevented.
