Abstract: A cylinder head cover is mounted on a cylinder head of an internal combustion engine to cover a camshaft supported by the cylinder head. The cylinder head cover includes a cover main body and a baffle plate. The cover main body includes a head mounting surface to be connected to the cylinder head and a bulging portion bulging away from the cylinder head farther than the head mounting surface. The bulging portion includes a recess that is recessed to approach the head mounting surface. The recess includes a bottom wall inclined with respect to a horizontal plane in a state in which the cover main body is mounted on the internal combustion engine. The baffle plate is joined to a surface of the bulging portion facing the camshaft at least at a section corresponding to the bottom wall of the recess.

Abstract: There is provided a sealing structure and a gasket which can seal both of a portion where a groove for mounting the gasket is formed and a portion where a groove for mounting the gasket is not formed when the portions are connected. The gasket includes a first gasket portion 110 which has a first mounted portion 111 to be mounted in a first groove 211 to come in close contact with a bottom face 211a of the first groove 211 and which is formed in a shape along an end portion of an outer wall portion 210 and a second gasket portion 120 which has a second mounted portion 150 to be mounted in a second groove 221 near a portion connected to the first gasket portion 110 and which is formed in a shape along an end portion 220 of a partition wall 220, the second mounted portion 150 having an inclined face for coming in close contact with the inclined bottom face 221a of the second groove 221.
