Claims

[Scope of utility model registration request]

The camshaft is rotatably supported by the cylinder head, and above it is arranged a valve lifter that contacts the cam nose, and further above the camshaft is arranged so that one end is in contact with the valve lifter, and the other end is in contact with the intake and exhaust valves, so that it can swing freely on the rocker shaft. In a multi-cylinder internal combustion engine equipped with an overhead cam type valve train having a supported rocker arm, a guide hole for slidingly holding a valve lifter and a guide hole for at least the same cylinder are connected above the cylinder head to each other. A substantially column-shaped support member is separately provided in which a lubricating oil passage communicating with the rocker shaft and a leg portion for fixing the rocker shaft are integrally formed. A multi-cylinder internal combustion engine characterized in that the lubricating oil passage of the support member and the lubricating oil passage formed inside the camshaft are connected to each other through an oil passage formed in the camshaft bearing. Engine valve train support device.
