The frame 3 has a double wall 30 consisting of an outer wall 31 and an inner wall 32. At the opposing point of the double wall 30 and the component housing part 60 of a block 6A, the lower end 32b of the inner wall 32 is positioned above the component insertion surface 61 on the lower end 60b side of the component housing part 60, and a waterproof wall 7 is provided at the lower end of the component housing part 60 and the outer edge of the double wall 30. The waterproof wall 7 is constituted of a first waterproof wall 11 extending right beside from the lower end of the component housing part 60 and the outer edge of the double wall 30 to the outer wall 31 side, and a second waterproof wall 12 extending downward from the end on the outer wall 31 side of the first waterproof wall 11 in parallel with the outer wall 31. |
