WIPO Patent Application WO/2017/168618
Kind Code:
A1
Abstract:
A lubricant supply structure for an internal combustion engine for a vehicle, wherein an oil reservoir (150) is formed facing the shaft end (50a) of a cam shaft (50) within a bearing (126) having a bearing hole (148) in which one end of the cam shaft (50) is rotatably fitted, and a spiral-shaped oil supply groove (153) is formed in the inner periphery of the bearing hole (148), the upstream end of the oil supply groove (153) communicating with the oil reservoir (150), A bearing is thereby provided in the cylinder head for rotatably supporting the one end of the cam shaft that constitutes a part of a valve mechanism, and as well as supplying the lubricant to the bearing thereof, it is possible to effective lubricate the sliding-contact parts of the cam shaft and the bearing while simplifying the cam shaft, without requiring processing of the cam shaft in order to form a lubricant channel.
