A part positioning device comprising a sensed member (2) formed by storing a wire (2b) having a target marker (2a) to be set an a car body (W) fitted to the tip thereof so as to be extracted and wound up, first sensors (3) detecting the extracted length of the wire (2b) when the target marks (2a) is set on the car body (W), second sensors (4) detecting the present position of the wire (2b) when the target marker (2a) is set on the car body (W), and a control means (5) controlling the movement amount of a self-traveling machine (1) so that the values detected by the first sensors (3) and the second sensors (4) are constant. |
