Abstract: A case for an endless transmission member includes a first case member attached to a vehicle-mounted internal combustion engine and a second case member attached to the first case member. The first and second case members define an accommodation chamber that accommodates an endless transmission member looped over rotating bodies of the engine. The first case member includes a communication hole that connects the accommodation chamber to the inside of the engine. The first or second case member includes a guide rib that guides lubricant from the accommodation chamber to the inside of the engine. In an orientation of the case when the engine is installed in a vehicle, the guide rib is provided along part of the lower side of the opening edge of the communication hole including the lower end of the opening edge.

Abstract: An internal combustion engine includes a cylinder head, a crankshaft, intake and exhaust camshafts, first and second chain covers, a chain, and a fastening bolt. The first chain cover having a cutout includes a first flange positioned at a specific edge portion of the cutout, which is positioned between the crankshaft and the camshafts, and a first boss through which a shaft portion of the fastening bolt is passed. The cylinder head includes a second flange, and a second boss into which the shaft portion is inserted, and which is disposed coaxially with the first boss. The liquid gasket is held between the second flange and the first flange. A groove is provided in at least one of a position between the first flange and the first boss of the first chain cover and a position between the second flange and the second boss of the cylinder head.
