A travelling vehicle equipped with obstacle detector sensors having, at the front of the vehicle body (1), a noncontact-type obstacle detector sensor (A) and a contact-type obstacle detector sensor (B), and a vehicle speed control device (20) adapted to automatically reduce the vehicle speed from a preset vehicle speed (v.sub.)0) to a predetermined vehicle speed (v.sub.1) when the noncontact-type obstacle detector sensor (A) detects an obstacle, adapted to automatically reset the vehicle speed to said preset speed (v.sub.0) when the sensor (A) does not detect the obstacle any more during such speed reduction, and adapted to automatically stop the travelling of the vehicle immediately when the contact-type obstacle detector sensor (B) detects the obstacle.
