PROBLEM TO BE SOLVED: To provide a mobile device in piping in which a frictional force in the operation of steering cables is reduced, two steering cables can reliably be operated with a small operating force and can be adjusted individually, and the tension can be kept constant.SOLUTION: A mobile device in piping includes: three wheels 2A-2C rotationally driven by a motor and longitudinally disposed in a rotation direction; two joint parts 3A, 3B for rockably connecting the three wheels in a horizontal direction and a vertical direction; two steering cables 5X, 5Y with one end fixed to the wheel 2A positioned in the top of a traveling direction, and extended in the rear of the wheel positioned in the head back through both sides of the remaining wheels 2B, 2C and the joint parts; and a tension controlling part 6 opposed to the wheel positioned in the head back, and connected with the other end of the two steering cables and capable of adjusting the tension of the two steering cables. Then, a cable guide member is provided in the second wheel 2B from the top of the traveling direction, the cable guide member that guides the two steering cables 5X, 5Y and replaces the left and right positions thereof.
【課題】操縦用ケーブルの操作時に摩擦力を軽減し、2本の操縦用ケーブルを小さな操作力で確実に操作でき、個別に調節可能としてその張力を一定に保持できるようにする。【解決手段】モータによって回転駆動されると共に回転方向へ縦並びに配置される3個の車輪2A〜2Cと、3個の車輪間を水平方向及び垂直方向へ揺動可能に連結する2個のジョイント部3A,3Bと、一端が走行方向の先頭に位置する車輪2Aに固定され且つ残りの車輪2B,2C及びジョイント部の両側方を通って後頭に位置する車輪の後方に延在された2本の操縦用ケーブル5X,5Yと、後頭に位置する車輪に対向されると共に2本の操縦用ケーブルの他端が連結され且つ2本の操縦用ケーブルの張力を調節可能な張力調節部6と、を備えている。そして、走行方向の先頭から2番目の車輪2Bに、2本の操縦用ケーブル5X,5Yをガイドして左右位置を入れ替えるケーブルガイド部材を設けた。【選択図】図1
