PURPOSE:To prevent vibration, by securing a scroll of a blower to a partitioning plate and removably fixing the partitioning plate to a pressure chamber through a plate-shaped elastic member. CONSTITUTION:A fan 1 is constituted of a motor 2, impeller 3, scroll 4, fan base 6 serving for a partitioning plate, plate-shaped joint 7 being an elastic member and a chamber 8 forming a pressure chamber. A clearance between the fan base 6 and the chamber 8 is enclosed by the plate-shaped joint 7, while it prevents vibration of the fan base 6 from being transmitted to the chamber 8. Accordingly, forming a blower device into a thin type can be promoted preventing the scroll from transmitting its vibration to the pressure chamber.
