Zusammenfassung:	A cover for an internal combustion engine is configured to be attached to an engine main body so as to cover a timing chain or a timing belt. The cover for the internal combustion engine includes insertion holes configured to receive a crankshaft or a camshaft. The cover for the internal combustion engine includes a first member made of a hard plastic and a second member made of a material different from the hard plastic. The first member is produced by insert molding with the second member embedded in the first member. A periphery of at least one of the insertion holes in the second member includes a joint surface that is joined to the first member. The joint surface includes annular grooves surrounding the insertion hole, the annular grooves being arranged in a radial direction of the insertion hole.
