A scraper is provided in a large end portion of a connecting rod in an inclined type of overhead camshaft engine to lubricate a timing system by dipping a lubricating oil stored in a lower portion of a crank case up. The scraper includes a bottom wall and a side wall set up on the bottom wall, and have a substantially L-shaped cross-section. An angle between the bottom wall and the side wall is set in a range of 60° to 90°. Thus, the droplets of the oil can be splashed to the side direction of scraper also in three-dimensional inclined direction, so that oil can be securely supplied to and lubricate the timing system which is offset from the scraper in a longitudinal direction of the crankshaft.
