ELECTRIC POWER SOURCE DEVICE FOR VEHICLE

摘要

An electric power source device for a vehicle has a suspended frame (16) having sloped sections (16c) extending obliquely outward and upward from two mutually facing side edges of a waterproof case (14). The outer peripheries of a lid member (15) and of an upper surface opening (14b) of the waterproof case (14) have extended sections (14a, 15a) extending upward so as to cover the sloped sections (16c) of the suspended frame (16). The extended sections (14a, 15a) block water flowing on the upper surface of the lid member (15) and water staying on the upper surface of the lid member (15), preventing the water from entering the inside of the waterproof case (14) from that outer periphery of the suspended frame (16) which penetrates through the joint surfaces between the lid member (15) and the waterproof case (14) in which a battery module (24) and a high-voltage electric component (33) are received.
