とを特徴とする過給機における潤滑構造。[Claims for Utility Model Registration] A housing in which a pair of rotors is housed vertically in parallel has bearings on the upper and lower sides for rotatably supporting the rotor shafts of both rotors, and a predetermined depth inside the housing. Each rotor shaft is provided with an oil chamber in which lubricating oil is injected, and the lower oil chamber located at the lower level houses a gear for transmitting driving force that is fitted on the shaft end side of the bearings of both rotor shafts. In the supercharger, an inner wall of the lower oil chamber has an upward slope along the rotational direction of the gear in order to splash up the lubricating oil in the lower oil chamber as the gear rotates. A lubrication structure for a supercharger, characterized in that a tilted surface for flipping up is formed.
