摘要： 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.

摘要： A heater (19) is disposed in an air flow duct (12) having an upper air outlet (22). An air filter (36) is disposed in a bypass duct (31) having an outlet (32) communicating with the upper outlet (22). Cool air flows into the bypass duct (31) from the air flow duct (12) upstream of the heater (19). Warm air is mixed with the cold air in the bypass duct (31) and is obtained either from the air flow duct (12) downstream of the heater (19) or is constituted by recirculated air from a vehicle passenger compartment.
