Abstract: A centrifugal blower includes a plurality of blades, a shroud, a main plate and a tubular portion. An air flow passage is formed between each adjacent two of the blades. When the blades are rotated, air, which is suctioned from one axial side into a suction port is conducted through the air flow passage and is radially outwardly discharged. The shroud has a cover region, which faces another axial side and is shaped in a convex arcuate form. An axial end part of the tubular portion, which faces the one axial side, has an end surface. The end surface and a second virtual line are parallel to each other, or a distance, which is measured between the end surface and the second virtual line in the axial direction, is progressively increased from a radially inner part to a radially outer part of the end surface.

Abstract: A blower includes a shaft and a centrifugal fan. The centrifugal fan includes a plurality of blades, a shroud and a main plate. Each of the plurality of blades has a leading edge and a trailing edge. At each blade, a negative pressure surface of an air inlet section of the blade, which is closer to the leading edge than the trailing edge, has a projection that projects toward a positive pressure surface of an adjacent one of the plurality of blades. At least a portion of the positive pressure surface of the air inlet section is inclined toward a forward side in a rotational direction of the centrifugal fan to progressively extend toward the forward side in the rotational direction as the portion of the positive pressure surface of the air inlet section extends toward the main plate.

Abstract: An actuator device includes an operating member that deforms in response to a change in temperature, and a heating member that applies heat to the operating member. The operating member deforms in response to a change in temperature within a range in which a stress generated between the operating member and the heating member remains at or below an elastic limit of the operating member.
