Abstract

A lubricant device of four-stroke engine is provided according to the present invention. The lubricant device is applicable to a four-stroke engine having a cylinder, a crank case, a rocker arm room and a cam room connected to the rocker arm room. The lubricant device mainly has the rocker arm room and the crank case be connected to each other, and the design of alternating oil supply and oil recycling channels enables lubricant mists to cycle from the crank case through the rocker arm room to the cam room and then be re-absorbed into the crank case, thereby allowing engines to be manipulated at various angles.
