Waterproof box with tiny and blind passages
When cleaning water hits a lower wall 33h of a first waterproof portion 33 of an upper cover 15, and the water is thrown up to the upper cover 15, a tapered outer wall 30b of the first waterproof portion 30 and a tapered inner wall 33g of the first waterproof portion 33 come into contact with each other, and are engaged with each other to close an entrance side of a tiny passage 27. Even if the water enters, the water enters a blind passage 33b to reduce the force of the water. The water of which force is reduced falls down. It is effective for improving waterproof performance to reduce the force of the water by the blind passage 33b.
