−にしたことを特徴とする過給機潤滑装置。′In an internal combustion engine with a supercharger, a tank is provided in the lubricating oil passage from the engine's main gear rally to the bearing of the supercharger to store a portion of the lubricating oil by bypassing the passage. Then, a control circuit that emits a signal for a certain period of time and an electric pump that is activated by the signal from this control circuit and supplies the lubricating oil in the tank to the bearing of the supercharger are installed, and the engine is supercharged for a certain period of time after the engine is stopped. A supercharger lubrication device characterized in that it lubricates a bearing part of a supercharger. ′
