To provide a travelling carriage having collision-countermeasure structure simplified without increasing the possibility of collision.SOLUTION: A travelling carriage 5 can travel on a plurality of first tracks 31 arranged along a first direction and also on a plurality of second tracks 32 arranged along a second direction orthogonal to the first direction, which is configured to comprise a travelling part and a driving part. The travelling part has at least four driving wheels, where directions of the four driving wheels are in parallel and the four driving wheels contact the first tracks 31 or the second tracks 32, at the time of both travelling along the first tracks 31 and travelling along the second tracks 32. The driving part rotates the four driving wheels respectively with a vertical direction as a rotation center so as to make a wheel center line, a line passing through the centers of the four driving wheels to intersect orthogonally with a contact line of a turning circle of spin turn, and then rotates the four driving wheels with the wheel center line as a rotation center so as to perform the spin turn.SELECTED DRAWING: Figure 1
【課題】衝突の可能性を上げることなく衝突対策に関する構成を簡略化した走行台車を提供する。【解決手段】第1方向に沿って配置される複数の第1軌道31、及び、第1方向と直交する第2方向に沿って配置される複数の第2軌道32の両方に沿って走行可能な走行台車5において、走行部と、駆動部と、を備える構成が提供される。走行部は、少なくとも4つの駆動輪を有し、第1軌道31に沿った走行時及び第2軌道32に沿った走行時の何れの走行時においても、4つの駆動輪の向きが平行であるとともに、4つの駆動輪が第1軌道31又は第2軌道32に接触する。駆動部は、鉛直方向を回転中心として4つの駆動輪をそれぞれ回転させることで、平面視において4つの駆動輪の中心を通る線である車輪中心線をスピンターンの旋回円の接線と直交させた後に、4つの駆動輪を車輪中心線を回転中心として回転させることでスピンターンを行う。【選択図】図1
