The waterproof tube is formed as a tubular body curved into an almost U-shape, and a holding portion 12 both sides of which consist of parallel planes 11 is formed in part of the portion 10 a of the tube which corresponds to the bottom of the U-shape. Further, internal walls 14, 15a, 15b to be oriented in a direction crossing a passage 10d extending from one end to the other end of the waterproof tube are formed on the inner surface of the tube near the holding portion. |
