PROBLEM TO BE SOLVED: To reduce the number of components and maintain waterproofness of a circuit board.SOLUTION: A waterproof retainer includes: a voltage detection unit 10 having a circuit board 1 and a box shaped case 2 which houses the circuit board 1; and a waterproof cover 6 which is fixed to a base 7 through a waterproof seal 8 and houses the voltage detection unit 10 in a waterproof space at the interior thereof. The case 2 has a substrate opening 2a which receives the circuit board 1, and the case 2 is fixed to an inner surface of the waterproof cover 6 so as to close the substrate opening 2a.SELECTED DRAWING: Figure 3

    【課題】回路基板の防水性を維持しつつ、部品点数を削減することである。【解決手段】回路基板1と、回路基板1を収容する箱形状のケース2とを有する電圧検出ユニット10と、ベース7に防水シール8を介して固定され、その内部の防水空間に電圧検出ユニット10を収容する防水カバー6とを備える防水固定装置であって、ケース2は回路基板1を受け入れる基板用開口2aを有しており、ケース2は基板用開口2aを塞ぐように防水カバー6の内面に固定されている。【選択図】図3
