To provide an unmanned carrier which enables improvement of accuracy of a stop position after conveyance without increasing in size of the unmanned carrier even if a dolly and a loaded workpiece are heavy objects.SOLUTION: An unmanned carrier 4 conveys a dolly 3, which has a frame 31 on which a workpiece 2 can be loaded and can be moved on a floor surface 6 through casters 30 by application of external force, while supporting the dolly 3 in a lower direction D than the frame 31 when viewed in a vertical direction and includes: multiple wheels, driving wheels 40 and steering wheels 41, which is brought into contact with the floor surface 6; a driving source 43 which drives at least the driving wheels 40; a connection part 45 which connects a vehicle body 42 to the dolly 3; and a biasing part 46 which is provided at the vehicle body 42, is brought into contact with the dolly 3 to support a part of a total weight of the dolly 3 and the loaded workpiece 2 when the vehicle body 42 and the dolly 3 are connected by the connection part 45, and biases the vehicle body 42 and the dolly 3 in a direction such that the vehicle body 42 and the dolly 3 are separated in an up-down direction U, D when viewed in the vertical direction.SELECTED DRAWING: Figure 4

    【課題】台車及び積載したワークが重量物であっても、無人搬送車を大型化することなく、搬送後の停止位置の精度を向上することができる無人搬送車を提供する。【解決手段】ワーク2を積載可能な架台31を有し外力が加わることでキャスタ30により床面6を移動可能な台車3を、架台31より鉛直方向の下方向Dにおいて台車3を支持して搬送する無人搬送車4であって、床面6と接する複数の車輪である駆動輪40及び操舵輪41と、少なくとも駆動輪40を駆動させる駆動源43と、車体42と台車3とを連結する連結部45と、車体42に設けられ、連結部45により車体42と台車3とが連結されている場合に、台車3に当接して、台車3及び積載したワーク2の総重量のうちの一部を支持すると共に、車体42と台車3とを鉛直方向の上下方向U,Dに離間する方向に付勢する付勢部46と、を備える。【選択図】図4
