To provide a wheel drive device that can maintain straight-running stability in all directions even when minute irregularities or the like exist on a grounding surface of a wheel, and to provide an omnidirectional moving carriage using the same.SOLUTION: A wheel drive device of the present invention comprises: a wheel 4 coupled to an axle; bearings 5a, 5b which turnably hold the axle 9; and a wheel cover 6 which wears the bearings 5a, 5b. The wheel cover 6 has openings 6a, 6b for wearing the bearings 5a, 5b respectively inside and outside the wheel 4. The outside opening 6b has a long hole shape which is wider than an outside diameter of the bearing 5b by a predetermined width in a height direction.SELECTED DRAWING: Figure 1

    【課題】ホイールの接地面に微小な凹凸等が存在する場合でも、全方向への直進安定性を維持することができるホイール駆動装置、及びそれを用いた全方向移動台車を提供する。【解決手段】本発明のホイール駆動装置は、車軸に接続されるホイール4と、車軸9を回動自在に保持するベアリング5a、5bと、ベアリング5a、5bを装着するホイールカバー6とを有し、ホイールカバー6には、ホイール4の内側と外側にベアリング5a、5bを装着するための開口部6a、6bがそれぞれ設けられ、外側の開口部6bは、ベアリング5bの外径よりも高さ方向に所定幅だけ広い長穴形状である。【選択図】図1
