摘要： 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.

摘要： In an insulator (21) inserted between a carburetor (30) and a cylinder (3) for a purpose of insulating heat, there are formed an intake passage (22) connected to the carburetor (30), and a pair of first air passages (23) connected to respective air flow paths (14) communicated with a pair of scavenging ports (10) formed in the cylinder (3). Air control valves (25) are respectively provided within a pair of first protruding portions (33) communicating with an air cleaner (32), and are connected to the pair of first air passages (23) via a pair of connection members (35). Portions from the air passages within the pair of first protruding portions (33) to the pair of first air passages (23) are respectively formed as smooth air passages in which a change of an inner diameter cross sectional area in a connection portion is small.
