The component-mounting surface 20 is positioned upward than the lower end of a peripheral part 34 with which the upper cover 10 is equipped. At the periphery of the base block 11, a first peripheral wall 31 is provided which is fitted to the peripheral part 34 of the upper cover 10. This first peripheral wall 31 is positioned inside the peripheral part 34 of the upper cover 10. The upper end of the first peripheral wall 31 is positioned higher upward than the lower end of the peripheral part 34 of the upper cover 10. Moreover, the component-mounting surface 20 is positioned higher upward than the upper end of the first peripheral wall 31. A drain hole 33 is provided in the periphery of the component-mounting surface 20. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
