Document Type and Number:
Japanese Patent JP5269060
Kind Code:
B2
Abstract:
An impeller element 14 includes a plurality of blades 13 disposed along an outer circumference of a circular support plate 12. Each blade 13 is divided into a plurality of blade sections in a rotational axis direction AX. At least one of the divided blade sections as a long-chord blade section 20 is configured such that a chord 28a as a line segment connecting a blade outer-circumferential edge 20b and a blade inner-circumferential edge 20a of the blade 13 in a cross section perpendicular to a rotational axis 17 of the blade 13 has a greater length than a chord 28b of another one of the blade sections as a short-chord blade section 21. The blade inner-circumferential edge 20a of the at least one long-chord blade section 20 having the longer chord 28a protrudes toward the inner circumferential side, relative to the blade inner-circumferential edge 21 a of the at least other one of the blade sections as the short-chord blade section 21 having the shorter chord 28b.
