<p><P>PROBLEM TO BE SOLVED: To provide a blower having improved blowing efficiency with higher static pressure, and reduced noises. <P>SOLUTION: In the blower where a straight line elongating the heightwise center point of a portion contacting a boss 1 of a blade 4 in the direction of a rotational center axis 30 to the outer periphery of the blade 4 perpendicularly to the rotational center axis 30 is defined as a straight line (a), a line joining the heightwise center points of the radii of the blades 4 in the direction of the rotational center axis 30 is defined as a radial center line (b), and a straight line connecting the center point to a selective point on the radial center line (b) is defined as a straight line (c), the straight line (c) is inclined to the straight line (a) toward a gas suction side. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
