    • In a handheld type OHV engine, an oil tank (13) is provided so as to be connected to one side wall running the length of a crankcase (6) and a cylinder block (7), the oil tank (13) houses oil mist generation means (36,37,38,39,40) to and a rotational movement section of a valve operation mechanism, and the oil mist generated in the oil tank is supplied from a crank chamber to a valve operation chamber of a cylinder head housing a reciprocating movement section of the valve operation mechanism, and is returned to the oil tank by utilising the pressure pulsations of the crank chamber and a one-way valve (51). It is thus possible to lubricate the inside of the crank chamber and the valve operation mechanism reliably regardless of the operational position of the handheld type OHV engine while reducing the overall height of the engine.

    • A seal structure in an engine, including a seal member interposed between a cylinder head having a slant at least at an intermediate portion of its upper end face to which a valve-operating cam chamber opens, and a head cover coupled to the upper end face of the cylinder head by a bolt to close the valve-operating cam chamber. The head cover has a fit wall portion formed thereon and fitted to an inner peripheral surface of the valve-operating cam chamber, and the seal member is mounted in a seal groove provided in an outer peripheral surface of the fit wall portion to come into close contact with an inner peripheral surface of the cylinder head. Thus, an interference can be provided equally at various portions of the seal member irrespective of the number of bolts used, and the seal member can always exhibit a good seal function.
