PROBLEM TO BE SOLVED: To connect a plurality of cylinders to each other and bend them without damaging a wire passed through a hollow part of the cylinders. SOLUTION: In the constitution of an internal pipe traveling truck, when at least two cylinders 1, 2 capable of passing a wire in a hollow part are connected to each other, independently oscillatory ring-shaped connection members 3 are interposed in a pivotably supported manner by a part to connect the cylindrical body 1, a regulation part 1c to regulate the angle of oscillation of the cylinders is provided on outer circumferential edge surfaces opposite to each other of the cylinders to be connected to both sides of the connection member, and the regulation part 1c is provided on a flange of the cylinder 1 on which the outer circumferential edge is abutted on the preset angle of oscillation.
