To provide an unmanned carrier with a simple structure having a lock function which can fix an attitude of a vehicle body while travel is stopped, and can perform loading and unloading with respect to a load carrying platform.SOLUTION: An independent suspension mechanism includes: a linear guide (guide support mechanism) 32 for movably guiding a wheel holding frame 31 for supporting an axle 41 of a wheel 40 only in a vertical direction to a vehicle body 20 against resilient force by a cylindrical coil spring (resilient means) 33; and a lock mechanism 38 switchable between a lock release state and a lock state in which movement of the wheel holding frame 31 in the vertical direction is inhibited. By a cushioning function by the independent suspension mechanism 30, an unmanned carrier is configured to: stabilize an attitude during travel of the vehicle body 20 installed with a load carrying platform; inhibit movement of the wheel holding frame 31 in the vertical direction by the lock mechanism 38 during travel is stopped; fix the attitude of the vehicle body 20 in a travel stop state; and perform loading and unloading to the load carrying platform.SELECTED DRAWING: Figure 2

    【課題】走行停止時には、車体の姿勢を固定して、上記荷台に対する荷積み・荷卸しを行うことができるロック機能を有する簡単な構成の無人搬送車を提供する。【解決手段】車輪40の車軸41を支持する車輪保持フレーム31を円筒コイルバネ(弾発手段)33による弾発力に抗して車体20に対して垂直方向にのみ移動可能に案内するリニアガイド(案内支持機構)32と、上記車輪保持フレーム31の上記垂直方向への移動を禁止するロック状態とロック解除状態とに切り替え可能なロック機構38と備える独立懸架サスペンション機構30による緩衝機能により、荷台が設置された車体20の走行中の姿勢を安定化し、走行停止時には上記ロック機構38により上記車輪保持フレーム31の上記垂直方向への移動を禁止して、走行停止状態での車体20の姿勢を固定して、上記荷台に対する荷積み・荷卸しが行われるようにする。【選択図】図2
