A lubricating device for an overhead valve type four-stroke engine, comprising a breather passage communicating with the first oil chamber, and an oil return passage communicating the lower part of the rocker arm chamber with the first oil chamber. (2) Overhead valve type 4 according to claim (1) of the utility model registration claim, characterized in that the small hole is bored from the bottom of the oil pan and faces the drain hole.
Cycle engine lubrication system.
