  "textContent": "A supercharging device for an engine is provided, which includes a supercharger provided to an intake passage of the engine, an actuator configured to drive the supercharger, and a controller including a processor configured to control the actuator to drive the supercharger when an operating state of the engine is in a given supercharging range, and to stop the supercharger when the operating state is in a non-supercharging range. The controller causes the actuator to forcibly drive the supercharger in the non-supercharging range when a temperature of the supercharger is lower than a preset temperature, and prohibits the forcible drive of the supercharger when a rotation speed of the supercharger during the forcible drive of the supercharger is lower than a preset rotation speed.",
