| abstract |
The impeller of an electric blower comprises a front face shroud, a rear face shroud, blades which consist of a metallic plate, and an inducer which has a hub and blades. The inducer is formed so as to be divided into two parts, that is, into a first inducer composed of a first hub and first blades, and into a second inducer composed of a second hub and second blades. The first inducer is disposed so that the edges of the first blades in the outer peripheral direction are disposed close to the front face shroud and so that the upper surface of the first hub is disposed so as to be in close proximity to and to be covered by the lower surface of a fastening body. |
