変装置。 The oil gear that supplies lubricating oil from the engine oil pump to the engine crank system, engine valve system, turbocharger, etc. is branched off and communicated with oil passages formed inside the crankshaft and conrod, and the oil pressure of the piston is controlled through this oil passage. In a compression ratio variable device for an internal combustion engine that changes the piston stroke according to the oil pressure supplied to the engine chamber, a shutoff valve that closes only when the engine starts is installed in the oil gear rally leading to the engine valve system and turbocharger. A variable compression ratio device for an internal combustion engine, characterized by:
