Abstract
A brush cutter is provided with fixing pieces projecting outward and opposing each other substantially at a middle position of a slit stretching between both ends of a clamp member. Accordingly, an outer pipe is clamped in the middle of an attachment housing and apart from an axial center of the outer pipe, so that a size of the attachment housing in an axial direction can be reduced and stress concentration on the outer pipe can be avoided.
