To provide an unmanned carrier achieve both securement of a proper ground contact pressure in an unmanned carrier and further reduction in a height dimension of a traction gear.SOLUTION: An engagement arm 26 is constituted to fluctuate around an output axis OS functioning as a supporting point between a non-traction condition and a traction condition by rotation of the output axis OS of an actuator 24, and a traction gear 20 is arranged in an unmanned carrier 1 for the output axis OS to be orthogonal to a traveling direction and a vertical direction of the unmanned carrier 1. By this arrangement, reduction in a height dimension of the traction gear 20 can be achieved. Also, as in the traction condition, a guide roller 28 enters an under side of a front frame 90b of a truck 90 and elevates the truck 90 from a floor face F, so a weight of the truck 90 is transferred to drive units 4, 4 of the unmanned carrier 1 via the traction gear 20. Thus, a ground contact pressure required for the traveling of the unmanned carrier 1 can be secured.SELECTED DRAWING: Figure 14

    【課題】無人搬送車における適正な接地圧の確保と牽引装置の高さ寸法のより一層の低減との両立を図ること。【解決手段】アクチュエータ24の出力軸OSが回転することによって、係合アーム26が、非牽引状態と牽引状態との間で出力軸OSを支点に搖動する構成とすると共に、出力軸OSが無人搬送車1の走行方向および鉛直方向の両方向に直交するように牽引装置20を無人搬送車1に配置する。これにより、牽引装置20の高さ方向の寸法の低減を図ることができる。なお、牽引状態において、ガイドローラ28が台車90の前側フレーム90bの下側に入り込み、台車90を床面Fから持ち上げるため、台車90の重量が牽引装置20を介して無人搬送車1の駆動ユニット4,4に伝達される。これにより、無人搬送車1の走行に必要な接地圧を確保することができる。【選択図】図14
