Abstract
An engine blower includes a centrifugal blower having a volute case in which a fan is accommodated; an engine attached to the centrifugal blower for driving the fan; a carburetor mounted to the engine via an insulator; and a lead wire that establishes conduction between the engine and the carburetor. The electrical potential difference between the engine and the carburetor can be eliminated, which prevents electrostatic discharge between the engine and the carburetor even when static electricity is built up in a volute case or a ventilation tube. Accordingly, ignition timing can be prevented from shifting due to an influence on an electrical circuit by the discharge within an ignition unit.
