An air supply device for a vehicle is provided to improve accuracy by assembling a motor assembly to an inlet duct and an outlet duct and supporting a rotary shaft through the motor assembly. An air supply device for a vehicle includes a motor assembly, an inlet duct(110), an impeller(180), an outlet duct(170), and an end plate(190). The motor assembly rotates a rotary shaft(120), and has an air flow channel(130a) formed through the top and bottom of the motor assembly. The inlet duct is joined onto the motor assembly, and guides air introduced through an inlet(111) to the air flow channel of the motor assembly. The impeller is joined beneath the rotary shaft, and compresses air by rotating together with the rotary shaft. The outlet duct is joined beneath the motor assembly and accommodates the impeller into the center thereof. The outlet duct has an opening(171) for guiding air passed through the air flow channel of the motor assembly toward the impeller, and a volute(172) for discharging air which is blown through the impeller to an outlet port(173). The end plate closes the open end of the outlet duct.
