Abstract
A supercharger is driven by a rotational force of a crankshaft of a combustion engine via a chain. The supercharger includes: a supercharger rotation shaft to which an impeller is fixed; a supercharger holder that rotatably supports the supercharger rotation shaft; and a hydraulic tensioner that is mounted on the supercharger holder and suppresses slack of the chain. In the supercharger holder, a supercharger lubricating oil passage that introduces a lubricating oil to the supercharger is formed. A part of the lubricating oil introduced to the supercharger lubricating oil passage is supplied to a hydraulic cylinder of the hydraulic tensioner through a branch path.
