  • Patent number: 7129410
    Abstract: In a fuse box mounted on a battery box, a lower end surface of a peripheral wall of an upper cover contacts a bottom wall of a lower cover that is locked to a case body of the fuse box or contacts a bottom wall of the case body to form a first watertight portion. A peripheral wall erect on the bottom wall of the case body is formed by spacing the peripheral wall at a pressure-reducing gap from an inner surface of the upper cover. A rib formed by outwardly bending an upper end of the peripheral wall of the case body is projected toward an inner surface of the peripheral wall of the upper cover to form a second watertight portion. The pressure-reducing gap is interposed between the first watertight portion and the second watertight portion.
