The rotor is rotatable while extending in a first direction. The bosses are mounted to the rotor. The support sections extend from the bosses in a second direction intersecting with the first direction. Each of the blades extends radially with respect to the bosses while protruding from the support sections in the first direction, and has: a first end portion directed to the bosses; a second end portion positioned at opposite sides to the first end portion; and a third end portion positioned at opposite side to the support section. Each first end portion of the blades is formed by at least one circular arc-shaped portion including a circular arc-shaped portion having a width of a half width of the first end portion of each first end portion or more in the first direction while being connected to each third end portion. |
