It is an object of the present invention to obtain a condenser without hot blow air generation, with an extremely low electric power consumption. A kit comprised of a pair of end caps with foldable legs and a pole support are releasably engaged to the canister and can be removed without tools. The first and second buffers selectively couple the first and second outputs to a common output. The crankcase cover is formed with a partition wall extending along the outer circumference of the clutch mechanism.
