US Patent 8359704 Engine blower

An engine blower includes: an engine integrated with a volute for driving a fan; a ventilation tube communicated with the volute; and a handle mounted to the ventilation tube. In the engine blower, the handle has a pair of cases that are assembled with each other, and a conductive resin layer is formed on a surface of a grip of the handle. The resin layer is integrated with gates exposed within the handle. A conductive spring having a coil compressed in a direction in which the cases are assembled with each other and a cable that is electrically coupled with the engine are disposed within the handle. The gate of the resin layer is brought into contact with the coil of the spring and is electrically coupled with the cable via the spring.
