Abstract
A blower casing has a through hole formed in an end face, through which extends a motor which is drivingly coupled to a fan. An annular fitting flange member is rigidly fitted on the outer peripheral surface of the motor and joined at its peripheral edge to a portion of the above end face of the casing surrounding the through hole, for mounting the motor on the casing. The above through hole of the casing has its inner peripheral surface formed with an annular ridge which sealingly abuts against an opposed outer peripheral surface of the fitting flange member.
