Claims

[Claims for Utility Model Registration] A gear case 3 is fixed to one side of an overhead valve type engine E, and a crankshaft 4, a valve drive camshaft 10, and a fuel injection pump drive camshaft 8 are connected within this gear case 3 to form a gear transmission mechanism. In a timing gear transmission for an engine that is interlocked and connected via a lubricating oil return path 1 formed in the cylinder block 2 from the gear case side mounting surface of the cylinder block 2.
A timing gear transmission for an engine characterized in that a lubricating oil outlet pipe 16 is inserted toward the engine 5, and the end of the lubricating oil outlet pipe 16 on the gear case side is positioned above the gear engagement part of the gear transmission mechanism 1. Lubricating device in equipment.
