Abstract
A centrifugal air-sending device has blades that each have a vane length in a first region that is greater than a vane length in a second region, and are each formed such that a proportion for which a turbo vane portion accounts is higher in a radial direction than a proportion for which a sirocco vane portion accounts in the first region and the second region. The blades that are located closer to an outer circumference than is a blade inner diameter of inner circumferential ends of the blades at end portions of the blades that are close to a side plate in an axial direction are defined as a blade outer circumferential portion that is formed such that a vane thickness of each of the blades in decreased in the radial direction from an inner circumference toward the outer circumference.
