Zusammenfassung:PROBLEM TO BE SOLVED: To provide a lubrication oil supply mechanism with improved mechanical efficiency of a supercharger.SOLUTION: A lubrication oil supply mechanism 1 supplies lubrication oils A1, A2 to an engine and a supercharger 130 attached to the engine and includes: a block side oil passage 14 for supplying the lubrication oil A1 to a cylinder block 110 of the engine; a block side oil pan 10 in which the lubrication oil A1 flowing in the block side oil passage 14 is stored, the block side oil pan 10 being disposed on a path of the block side oil passage 14; a head side oil passage 24 for supplying the lubrication oil A2 to the supercharger 130; and a head side oil pan 20 in which the lubrication oil A2 flowing in the head side oil passage 24 is stored, the head side oil pan 20 being disposed on a path of the head side oil passage 24. The block side oil passage 14 and the head side oil passage 24 are formed as oil passages independent of each other. 【課題】過給機の機械効率を向上させることができる潤滑油供給機構を提供する。【解決手段】エンジンおよびエンジンに取り付けられる過給機130に潤滑油A1・A2を供給する潤滑油供給機構1であって、エンジンのシリンダブロック110に潤滑油A1を供給するためのブロック側油路14と、ブロック側油路14の経路上に配置され、ブロック側油路14を流れる潤滑油A1が貯溜されるブロック側オイルパン10と、過給機130に潤滑油A2を供給するためのヘッド側油路24と、ヘッド側油路24の経路上に配置され、ヘッド側油路24を流れる潤滑油A2が貯溜されるヘッド側オイルパン20と、を具備し、ブロック側油路14とヘッド側油路24とを互いに独立した油路として構成する。【選択図】図1
