PROBLEM TO BE SOLVED: To perform accurate moving distance measurement regardless of a variation in a driving wheel diameter.SOLUTION: An automatic transport vehicle 10 includes two driving wheels 13 and 14 provided in different positions in a right and left direction of a vehicle body (a frame 11), and the steering is performed by a difference in rotational speeds of the two driving wheels 13 and 14. The automatic transport vehicle 10 includes moving distance measurement wheels 17 and 18 provided separately from the driving wheels 13 and 14, which are provided so that rotational shafts 17a and 18a can move relatively in a pressing direction with respect to a travelling surface in a state of being pressed on a travelling surface side by pressing means irrespective of an attitude variation of the vehicle body, and rotary encoders 24 and 25 for detecting the number of rotations of the moving distance measurement wheels 17 and 18. The automatic transport vehicle 10 includes calculation means (a control device 26) for calculating a moving distance of the vehicle body based on a detection signal of the rotary encoders 24 and 25.

    【課題】駆動輪径の変動に拘わらず正確な移動距離計測を行う。【解決手段】自動搬送車10は、車体(フレーム11)の左右方向において異なる位置に設けられた2個の駆動輪13,14を有し、両駆動輪13,14の回転速度の差により操舵が行われる。駆動輪13,14と別に設けられ、かつ回転軸17a,18aが走行面に対する押圧方向に相対移動可能かつ車体の姿勢変動に関わりなく走行面側に押圧手段により押圧された状態で設けられた移動距離計測輪17,18と、移動距離計測輪17,18の回転数を検出するロータリエンコーダ24,25とを備える。自動搬送車10は、ロータリエンコーダ24,25の検出信号に基づいて車体の移動距離を演算する演算手段(制御装置26)を備える。【選択図】図2
