<p>PURPOSE:To improve radio wave fault resistance, corrosion resistance by hermetically sealing the contact surface of a metal base of a control module with control module mounting flange of a metallic body. CONSTITUTION:In a control module 1 having an aluminum die cast metal base 2, a sensor 17 is inserted in the flange 4 of an aluminum die cast body 3, and fixed with a mounting screw 7 an O-ring groove 5 is made in the contact part of the base 2 with the flange 4, and a hermetically sealing structure is generated by fitting an O-ring in the groove 5.</p> |
