Abstract
A cylindrical memberis provided with a pair of slitsextending in the axial direction of the cylindrical member. The opening widths of the pair of slitsin the circumferential direction of the cylindrical memberare narrower on the outside (opening widths W2, W4) of the cylindrical memberthan on the inside (opening widths W1, W3) thereof. This makes it possible to prevent rainwater and the like from reaching a communication holeinside the cylindrical memberand quickly discharge the rainwater and the like intruded into the inside of the cylindrical memberto the outside of the cylindrical member. Accordingly, it is possible to effectively prevent the rainwater and the like from intruding into the inside (hollow portion) of a gear cover, thereby enabling to improve a water exposure reliability.
