Abstract
A relief valve is interposed in an oil supply passage, and the relief valve internally includes a bottom passage for supplying oil from one oil supply passage to another oil supply passage. Since any branched oil passage for a relief valve is not required to be provided, it is possible to reduce the machining steps and machining cost. Further, since a space for disposing a branched oil passage is not required and the increase in space for disposing the relief valve can be reduced, the engine can be miniaturized.
