Abstract:
1. A fuse box which accommodates a bus bar connected with a battery terminal in a case body and has a fuse connected with said bus bar in said case body, said fuse box being mountable on a battery box with an upper cover in connection with said case body, wherein: a lower end surface of a peripheral wall of said upper cover is brought into contact with a bottom wall of a lower cover that is locked to said case body of said fuse box or brought into contact with a bottom wall of said case body to form a first watertight portion; a peripheral wall erect on said bottom wall of said case body is formed by spacing said peripheral wall at a pressure-reducing gap from an inner surface of said upper cover; an upper end of said peripheral wall of said case body is bent and projected toward an inner surface of said peripheral wall of said upper cover to form a second watertight portion; said pressure-reducing gap is interposed between said first watertight portion and said second watertight portion; and said pressure-reducing gap reduces a high pressure of water which has penetrated into said fuse box from the outside through said first watertight portion, thus suppressing said water from passing through said second watertight portion disposed above said first watertight portion.
