Abstract
An electrical junction box housing includes: a case having an opening portion; a cover closes the opening portion; and a gasket fitted to a groove portion of the opening portion. The groove portion includes a case-side seal face in contact with the gasket, an inner wall is located on the inner side of the case-side seal face and protrudes upward, and an outer wall is located on the outer side of the case-side seal face and protrudes upward. The cover includes a cover-side seal face in contact with the gasket, and a water stop wall protruding downward from the outer side of the cover-side seal face. A first clearance is formed in the vertical direction between the water stop wall and an outer surface of the case, and a second clearance is formed in the radial direction between the water stop wall and the outer wall.
