Abstract
An engine blower includes a centrifugal blower, an engine, and a frame for supporting the centrifugal blower. The centrifugal blower is supported by a back support of the frame via a flexible vibration-proofing section while being connected to the back support via a belt-shaped stopper. An engaging hole is provided on at least one of the centrifugal blower and the back support, and a thick engaging section is provided on at least one end of the stopper for being engaged with the engaging hole. When the stopper is inserted into the engaging hole and the one end of the stopper is pulled, the engaging section is engaged with the engaging hole. By further pulling the one end of the stopper, the engaging section is tightly buried into the engaging hole. Thus, the stopper can be reliably attached to the centrifugal blower or the back support.
