Drainage construction of a waterproof cover of an electrical connection box

摘要

A waterproof cover (13) is provided on an upper surface (11b) of a casing (11) of an electrical connection box (10). The waterproof cover (13) is formed with a recess (13b) for collecting water fallen down on the outer surface of the waterproof cover (13). One end of the recess (13b) with respect to a longitudinal direction is raised to form a water-diverting portion (13d), a rib (13c) projects up at the other end of the recess (13b), and a dropping portion (13e) is provided below the rib (13c). Waterdrops M that fall down on the outer surface of the waterproof cover (13) stay temporally in the recess (13b) and drain along the dropping portion (13e) when the water level thereof exceeds the rib (13c). Further, a slanted guide (12c) projects from a bracket (12) below the dropping portion (13e).
