To exactly obtain control information from a running sign even if a leading vehicle stops in the vicinity of the running sign: and to control power consumption.

The leading vehicle 1 (a golf cart) allowed automatic running along a running path 50 based on the control information from a contactless IC tag 51 serving as the running sign comprises: an encoder 36 serving as a distance detection means for detecting running distance; a transmission circuit 32c serving as a transmission means transmitting a golf cart transmission signal for transmitting the control information from the contactless IC tag 51 based on the running distance X detected by the encoder 36; a reception circuit 32a serving as a reception means receiving the control information; and a control circuit 13 serving as a control means controlling running based on the control information received by the reception circuit 32a. The transmission of the golf cart transmission signal is suspended when it seems that the reception of no golf cart transmission signal by the contactless IC tag exists, controlling the power consumption.
