PROBLEM TO BE SOLVED: To constitute drain structure for simply, surely exhausting rainwater penetrated in an envelope of a cabtire cable on midway of the envelope, and reduce cost by making an additional member unnecessary. SOLUTION: A cabtire cable 36 formed by bundling a plurality of single wire harnesses 37, then, cylindrically covering the bundled harness 37 with an envelope 36a is used as a cable which outputs an instruction signal from a control box 31 to a control bulb. Each single wire harness 37 introduced from the envelope 36a is connected to upper and lower terminals of a control bulb through a waterproof connector. An exposure part 39 where the envelope 36a is peeled off so that each single wire harness 37 is annularly exposed outward is formed in a control box 31 side part of the envelope 36a housed in the side position of a control box 31, and water penetrated along between single harnesses 37 in the envelope 36a from the single wire harness 37 introducing part of the envelope 36a is exhausted from an exposed part 39. The exposed part 39 is formed in a waterproof connector side lower than an upper end turned up part 40 of a control box 31 side part of the envelope 36a. |
