する内燃機関のシリンダヘツドカバー。 In a cylinder head cover for an internal combustion engine in which a chain chamber for a valve mechanism is provided at the front end of the cylinder block and cylinder head, a first partition wall extending along the longitudinal direction is located approximately in the center of the cylinder head in the longitudinal direction, and is adjacent to one side wall. At the same time, a second partition wall and a third partition wall are formed along the width direction so as to connect the front end and rear end of the first partition wall with the other side wall, respectively, and exclude the upper part of the chain chamber. A plate-shaped undercover is attached to the partition wall so as to cover substantially the entire surface thereof, and a blow-by gas passage section surrounded by the first to third partition walls and a fresh air passage section outside the partition wall are defined. A blow-by gas inlet and a blow-by gas outlet are disposed approximately diagonally on the gas passage, and a fresh air intake is disposed at the rear end of the fresh air passage. A cylinder head cover for an internal combustion engine characterized by having a front end opened toward a chain chamber.
