The main shaft portion is screw-coupled to the clutch and a direction in which the screw-coupling between the main shaft portion and the clutch is tightened corresponds to only one rotational direction of an engine. The casing has a single opening for inserting therein the worm and worm wheel, and the opening is closed with a lid that also functions to prevent the worm from coming off the casing.
