Abstract

The invention provides a blower unit for a vehicle, which can prevent the generation of vortexes in an air passage from an external air introducing port, an internal air introducing port to a air introducing port of the blower unit and reduce noise. The blower unit for the vehicle comprises a casing, which includes an air passage and provided with an inside and an outside air introducing port; a rotary damper which opens or closes the inside or the outside air introducing port, and a blower which introduces air from the introducing port to the air passage. The air passage has a fan accommodating portion which is provided on a leeward side of the damper and accommodates the fan of the blower. The casing has a wall portion ranging from a portion near an end portion of a movable range of the rotary damper to a portion near an end portion on a windward side in the fan accommodating portion in the casing, and an inner side surface of the wall portion is formed to be a convex surface projecting toward the air passage. The external air introducing port is disposed in an axial direction of a rotating shaft of the motor of the blower unit. An inner surface part of an enclosed part of the rotary damper has a convex surface projecting toward the damper rotating shaft.

Description
