The evaporated fuel processing device may include a pump unit including a pump body configured to pump out evaporated fuel generated in a fuel tank to an intake passage, and a pump controller configured to drive the pump body; and a controller configured to cause the pump controller to control the pump body. When an index related to a temperature of the pump unit exceeds a predetermined range, the controller may restrict the driving of the pump body.
