ELECTRIC CONNECTION BOX

摘要

An electric connection box for an automobile effectively prevents entry of water into the box and allows water having entered the box to be easily discharged. The electric connection box has a base block (11) having a component mounting surface (20) on which an electric component such as a relay (30) is mounted, and also has an upper cover (10) for covering the electric component. The component mounting surface (20) is located above the lower end of a peripheral section (34) of the upper cover (10). On the outer periphery of the base block (11) is formed a first peripheral wall (31) fitting in the peripheral section (34) of the upper cover (10). The first peripheral wall (31) is located inside the peripheral section (34) of the upper cover (10). The upper end of the first peripheral wall (31) is located above the lower end of the peripheral section (34) of upper cover (10). The component mounting surface (20) is located above the upper end of the first peripheral wall (31).
