To achieve downsizing of a driving wheel unit in a vertical direction.SOLUTION: A driving wheel unit 3 is attached to an automatic transportation dolly 1 including a dolly body 11 and casters 12 supporting the dolly body 11 from below to drive the automatic transportation dolly 1. The driving wheel unit 3 includes: a driving wheel 33; a driving mechanism 34 which rotationally drives the driving wheel 33 around a driving axis J1 oriented in a horizontal direction; and a steering mechanism 36 which changes an orientation of the driving wheel 33 around a steering axis J2 oriented in a vertical direction. At least a part of the steering mechanism 36 is located between an upper end and a lower end of the driving wheel 33 in the vertical direction. In a state that the driving wheel unit 3 is attached to the dolly body 11, an entire part of the steering mechanism 36 is located below an upper surface of the dolly body 11.SELECTED DRAWING: Figure 2

    【課題】駆動輪ユニットを上下方向に小型化する。【解決手段】駆動輪ユニット3は、台車本体11と、台車本体11を下方から支持する複数のキャスタ12と、を備える自動搬送台車1に取り付けられて、自動搬送台車1を駆動する。駆動輪ユニット3は、駆動輪33と、水平方向を向く駆動軸J1を中心として駆動輪33を回転駆動する駆動機構34と、上下方向を向く操舵軸J2を中心として駆動輪33の向きを変更する操舵機構36と、を備える。操舵機構36の少なくとも一部が、上下方向において駆動輪33の上端と下端との間に位置する。駆動輪ユニット3が台車本体11に取り付けられた状態で、操舵機構36の全体が、台車本体11の上面よりも下側に位置する。【選択図】図2
