ABSTRACT:
In an engine-driven handheld vacuum/blower, a first grip is provided as one part of an outer shape of an engine casing in which an engine is mounted, and a second grip is formed on a fuel tank which forms another part of the outer shape of the engine casing. The first grip and the second grip are positioned on the opposite sides of the center axis of the engine. Therefore, since there is no unbalanced load applied on either of both the hands, an operator can easily maintain the posture during operation, and can work with the vacuum/blower under good efficiency.
