<p>PURPOSE:To surely suppress the intrusion and leakage of the corrosive liquid by a double seal structure by forming a case body from the upper and lower terminal plates and a cylindrical body and arranging an electric power source side seal part and a motor side seal part at the upper and lower edges of the cylindrical body. CONSTITUTION:Aa for a connection terminal 9, an electric power source side seal part 27 and a motor side seal part 28 are arranged on both the sides of a cylindrical body 25. In this case, the motor side seal part 28 is constituted of a motor side terminal, cylindrical body 30A, lower part terminal plate 31 as lower part substrate, a plurality of metal seal rings 33A, etc. While, the electric power source side seal part 27 is constituted of an electric power source side terminal 36, a plurality of gaskets 26A and 26B, etc., and an upper part terminal plate 37 is placed at the upper edge of the cylindrical body 25 through the gasket 26. The motor side and electric power source side terminals 36 are connected by a conductor 41, inside the cylindrical body 25. Accordingly, the intrusion and leakage of the corrosive liquid can be surely suppressed by a double seal structure.</p> |
