PROBLEM TO BE SOLVED: To provide an unmanned transport vehicle in which a magnetic sensor is capable of properly detecting magnetism of a magnetic body on a road surface regardless of a relief on the road surface.SOLUTION: An unmanned transport vehicle 1 comprises: a vehicle body 10; a magnetic sensor 2 for detecting magnetism of a magnetic body M provided on a road surface F; and a pair of rollers 3a, 3b provided at a space, in a right angle direction Y where is horizontal and has a right angle to a travel direction X where the vehicle body 10 travels, and roll on the road surface F in the travel direction X. The unmanned transport vehicle 1 has a swing mechanism 5 for supporting the magnetic sensor 2 and rollers 3a, 3b, in a manner in which the magnetic sensor and rollers can oscillate around an axial line K extending in the travel direction X above the magnetic sensor 2 and between the pair of rollers 3a, 3b, to the vehicle body 10. The unmanned transport vehicle 1 has a slide mechanism 6 for supporting the swing mechanism 5 so as to slide move freely in a vertical direction Z to the vehicle body 10, and energizing the swing mechanism downward.SELECTED DRAWING: Figure 1
【課題】磁気センサが路面の起伏によらずに路面の磁気体の磁気を適切に検出することができる無人搬送車を提供する。【解決手段】無人搬送車1は、車体10と、路面Fに設けられた磁気体Mの磁気を検出するための磁気センサ2と、車体10が走行する走行方向Xに対して直角かつ水平な直角方向Yに互いに間隔をあけて配置され、路面Fを走行方向Xに転動する一対のローラ3a、3bと、を備える。無人搬送車1は、磁気センサ2及びローラ3a、3bを、車体10に対して、磁気センサ2の上方かつ一対のローラ3a、3b間で走行方向Xにのびる軸線Kの周りに揺動可能に支持するスイング機構5を備える。無人搬送車1は、スイング機構5を、車体10に対して上下方向Zにスライド移動可能に支持し、下方に付勢するスライド機構6を備える。【選択図】図1
