Abstract
The impeller of an electric blower includes a front shroud, a rear shroud, sheet-metal blades, a hub part, and an inducer having a plurality of blade parts. The inducer is configured to be divided into two parts: a first inducer composed of a first hub part and first blade parts; and a second inducer composed of a second hub part and second blade parts. The first inducer is disposed such that outer-peripheral blade-tips of the first blade parts are disposed in the proximity of the front shroud, and that the upper surface of the first hub part is proximally covered by the lower surface of a fastener.
