Abstract
The present invention proposes an electric blower which can strongly hold and fix a sleeve onto a frame, and eventually provide high reliability. An electric blower 1 includes a centrifugal fan 2; a shaft 9 installed integrally rotatably with the centrifugal fan 2; a sleeve 16; a bearing 17 provided in the sleeve 16 and adapted to rotatably support the shaft 9; a diffuser 6 provided with a through hole 21 in which the sleeve 16 is fixed; a recess 41 provided in an outer circumferential surface of the sleeve 16; and a stopper 43 filling a gap between the diffuser 6 and the recess 41 and adapted to harden and thereby prevent the sleeve 16 from being detached from the through hole 21.
