Title:
VENTILATION FAN FOR DUCT
Document Type and Number:
Japanese Patent JP3445428
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable a motor for a blower to be fixed without generating any vibrating sound.
SOLUTION: This ventilation fan is constructed such that a motor 15 for a blower has a fixing piece 25 protected at a flange section 24 and the fixing piece 25 is fixed with screws 29 to a main body frame 13. In this case, the surface of the main body frame 13 for fixing the motor 15 is provided with an inclination 27 directed toward the fixing direction of the motor 15 from its central side to an outward side, thereby the extremity end of the fixing piece section 25 of the motor 15 is spaced apart from the main body frame 13, so a so-called 'tip-contact' is eliminated and instead a flange part 24 other than the fixing piece section 25 of the motor 15 is abutted against the main body frame 13 and this may prevent a repetition of contact and spaced-apart motion from the spaced-apart state with the main body frame 13 from being carried out.
