摘要： A dust collector-equipped power cutter, which is easy to handle in operation and convenient for storage and transportation thereof and is capable of preventing dusty air from flowing back to the cutter portion when a cutting operation is interrupted, includes a main body, a cutter, a dust-sucking fan, and a dust hose assembly. The dust hose assembly includes a first dust hose section and a second dust hose section and a hose connector joining the first hose section and the second hose section. Each of the hose sections has a spiral rib on an outer peripheral surface, and the hose connector has a spiral groove on an inner wall of each end portion, the dust hose section and the hose connector being adapted to be interconnected with each other through a threaded engagement between the spiral rib and the spiral groove. The hose connector is provided with a check valve to prevent back flow when a cutting operation is interrupted or terminated.

摘要： A vibration-isolating member is formed of an elastic material, and has a mounting hole at the center thereof, a large diameter section at an end of the mounting hole, a groove at the periphery of the large diameter section, and a flange. One of a vibration-source-side member and a vibration-receiving member is fitted into each of the large diameter section and the groove. An end opposite from the large diameter section is secured to one of the vibration-receiving member and the vibration-source-side member by a mounting member. Since the inside diameter of the large diameter section is larger than any other part of the mounting hole, either of the vibration-source-side member or the vibration-receiving member and the mounting member can be received. The flange prevents the vibration-isolating member from disengaging from one of the vibration-source-side member and the vibration-receiving member.
