Claims

[Claims for Utility Model Registration] The engine is equipped with a sub-timing pulley, and a timing belt is wound between the camshaft pulley attached to the tip of the camshaft and the sub-timing pulley. In an engine in which power is transmitted from the shaft to the sub-timing pulley by a gear, the gear that transmits power from the crankshaft to the sub-timing pulley constitutes a gear-type oil pump.
