<p>PROBLEM TO BE SOLVED: To precisely measure a wire drawing-out angle, by entirely separating a detection sensor for a drawing-out angle of a wire which connects a preceding vehicle to a following vehicle from a sensor that measures a drawing-out length of the wire.SOLUTION: A connection sensor includes a base 4a which is attached to the front of a following vehicle or to the rear of a preceding vehicle, a linear encoder part 3 which is fixed to the base 4a and measures a drawing-out length of a wire 2, and a wire guide part 4 which is arranged in front of the linear encoder part 3, for guiding the wire 2 that is drawn out. The wire guide part 4 is connected in a manner in which it is rotated independently of the linear encoder part 3 around an axis 4b extended in vertical direction from the base 4a, and by detecting a rotation angle around the axis 4b in the vertical direction of the wire guide part 4 with a rotary encoder of the linear encoder part 3, a drawing-out angle of the wire 2 is measured.</p> |
