Abstract
A double overhead camshaft engine has a pair of camshafts, interconnected by gearing, which are disposed in juxtaposition over a cylinder head and supported by bearings. Either one of the camshafts is coupled to a crankshaft by a timing belt. A sealing member is disposed between the engine and a front cover so as to sealingly enclose and hide the timing belt. The sealing member, in the form of a rib forming a closed loop, is divided into a plurality of rib segments, at least one of which is formed integrally with the bearing member.
