To provide an autonomous control type work machine which is an all-wheel drive vehicle and can position a charging terminal to a power supply terminal in a small number of trials despite having charging terminals near driving wheels.SOLUTION: A work machine 10 moves forward by the driving force of rear wheels 12L and 12R, and the forward movement causes a top plate 38 on the side of a work-machine-side coupling member 36 to ride on a slope portion 46 on the side of a station-side coupling part 43. When viewed from the work machine 10, the slope portion 46 has an upward slope, so that a front wheel 11 rises by a distance δ from the ground. Since the front wheel 11 does not receive the resistance of the ground, when the rear wheels 12L and 12R move forward, the work-machine-side coupling member 36 easily moves in a width direction, and as a result, the station-side coupling part 43 is sufficiently inserted into the work-machine-side coupling member 36.SELECTED DRAWING: Figure 8

    【課題】全輪駆動車であって、駆動輪の近傍に充電端子を備えているにも拘わらず、少ないトライで給電端子に充電端子を位置合わせることができる自律制御型作業機を提供する。【解決手段】後輪12L、12Rの駆動力で作業機10が前進し、この前進によりステーション側結合部43側の勾配部46に、作業機側結合部材36側の天板38が乗り上がる。勾配部46が作業機10から見ると上がり勾配であるため、前輪11が地面から距離δだけ浮き上がる。前輪11が地面の抵抗を受けないため、後輪12L、12Rで前進されると、作業機側結合部材36が車幅方向に簡単に移動し、結果、作業機側結合部材36にステーション側結合部43が十分に挿入される。【選択図】図8
