PROBLEM TO BE SOLVED: To provide a cylinder head cover, capable of readily joining a head cover body and a baffle plate. SOLUTION: In this cylinder head cover 10, a laser beam L is made to irradiate directed toward an end part of a fixed rib 38, formed in a bottom part of the head cover body 12 from the opposite side of the head cover body 12 via the baffle plate 30. An end part of the fixed rib 38 is melted by the laser beam L, passing through the baffle plate 30. A contact part of the baffle plate 30 with the fixed rib 38 is melted by heat of the melted end part of the fixed rib 38. Thus, since the head cover body 12 and the baffle plate 30 are welded, a gasket 36 sandwiched by the head cover body 12 and the baffle plate 30 will not be damaged. Accordingly, welding work is facilitated. |
