PURPOSE:To perform surely the indication of an oil flow even when the flow speed of the oil flow is reduced with an intention by a method wherein only the aperture of a part of an oil piping to be equipped with an oil flow instructor is narrowed slenderly to reduce the area of the flow path of circulating oil. CONSTITUTION:An oil flow instructor 20 is equipped as to make a blade 21 to cross at right angles with an oil piping 18, namely as to cross at right angles with an oil flow. Flanges 22 to be connected respectively to the cooler side and the oil pump side are formed to the tube body 23 at both the edges of the oil piping 18. The aperture of the part to be inserted with the blade 21 is formed narrower as to throttle the tube body 23 than the aperture of the parts of the tube body 23 fitted respectively with the flanges 22. When oil flows, the blade 21 is pushed to instruct existence of a flow.
