A blower for a vehicle is provided to prevent the loss of inside air or outside air in an inside air mode or an outside air mode and to prevent the degradation of the heating efficiency in an inside/outside mixing mode. The blower for a vehicle is composed of a duct body(210), an inside air inlet(220), an outside air inlet(230), an inlet duct(200) having a connection wall(240) interconnecting the inside air inlet and the outside air inlet, and an opening/closing unit(300) for opening/closing the inside air inlet and the outside air inlet. The opening/closing unit contains a rotation shaft(310A), a guide roller(310) and first and second rollers(320,330), and an inside/outside air changing door(340). The guide roller is formed between the inside air inlet and the outside air inlet. The first and second rollers are installed separately in the inside air inlet and the outside air inlet of the inlet duct. |
