Abstract
The same size casing is used for interior air blowers of a combination air conditioning and heater interior unit disposed in left- and right-hand drive vehicles, respectively. A casing width is made nearly constant from a start-of-winding position to an end-of-winding position. An approximately central fan datum line which passes through a fan is offset to a suction port side with respect to a casing datum line which passes through an approximately central part of a portion of the casing parallel to a blower rotational axis. A flange portion of a motor holder is located at a position offset to one side (suction port side) along the rotational axis rather than an opposite side along the same direction in the casing. By replacement of impression cores it is possible to manufacture the casings for right- and left-hand drive vehicles, respectively.
