An engine room temperature rise restricting apparatus including an open and close detector of the grille shutter, and a controller including a CPU and a memory coupled to the CPU, wherein the CPU and the memory are configured to perform: detecting a stuck-closed failure of a grille shutter of a condition that the grille shutter remains closed regardless of an open instruction for the grille shutter, based on signal from the open and close detector; and controlling a speed ratio of a continuously variable transmission so that an upper limit of an engine rotational speed or an engine driving force when the stuck-closed failure is detected is smaller than an upper limit of the engine rotational speed or the engine driving force when the stuck-closed failure is not detected.
