摘要：PROBLEM TO BE SOLVED: To provide an electric wire protection pipe capable ofeasily controlling a route and manufacturing while maintaining airtightness with a simplestructure, and a wire harness in which an electric wire is inserted into the electric wire
protection pipe. SOLUTION: An electric wire protection pipe 1 has a straight pipe 2 havinga locking structure 2a at its end, and a valley portion 31 and a mountain portion 32 whichare connected to the straight pipe 2 in the locking structure 2a in the longitudinaldirection. And a continuous bellows-shaped pipe 3. The locking structure 2a includes alocking portion 21 in which a part of the inner peripheral surface of the straight pipe 2 isprojected inward. The bellows-shaped pipe 3 has a trough portion 31 at the end on theside connected to the straight-shaped pipe 2. The inner diameter of the locking portion21 is smaller than the outer diameter of the peak portion 32 and larger than the outerdiameter of the valley portion 31. In the locking structure 2a, the straight pipe 2 and thebellows pipe 3 are locked between the peak portions 32 in which a part of the straightpipe 2 and the outer peripheral surface of the valley portion 31 are in contact with eachother and which are adjacent to each other. Since the parts 21 are fitted together, theyare fixed to each other. [Selection diagram] Fig. 6
