## Abstract

An evaporative fuel treatment apparatus, which is loaded on a hybrid vehicle equipped with a fuel tank and a battery mounted forward of the fuel tank, has a sealing valve for sealing evaporative fuel in the fuel tank. The sealing valve is disposed between the battery and the fuel tank and is arranged above the battery. The evaporative fuel treatment apparatus can prevent fuel leakage from the sealing valve more reliably.
