<p>PROBLEM TO BE SOLVED: To reduce manufacturing costs and to improve reliability by ensuring waterproofing at a certain level without using O-shape ring or adequately enhancing accuracy of alignment among terminals of a connector unit and electrodes on a printed board. SOLUTION: To store an electronic circuit board in a metal case 100 with opening units formed on continuous two faces, this invention closes one opening face of the case 100 by mounting a connector unit 200 for electric signals input/ output as well as power signals input/output responding to the electronic circuit board, closes the other opening face by mounting an upper lid 300 on the opening face of the case 100, and forms a seal unit 60 by applying sealing materials such as hot melt to the circumference of the connector unit 200 and the circumference of the upper lid 300 and seals the case 100 in a closed condition.</p> |
