摘要 PROBLEM TO BE SOLVED: To perform right angle-traveling, moving to the other lane while completely suppressing influence of an exhaust gas and noise on environment. SOLUTION: Electric power fed from a power source device 7 provided in every lane 71 is fed as operation electric power 1A of respective electric motors 20-22, and a part of the operation electric power 1A is accumulated by an electricity accumulation device 4. When right angle-traveling to the other lane is performed, the accumulated electric power 4A is fed to a traveling electric motor 21 instead of the operation electric power 1A from an electricity feed device 1 stopped according to cut-off of the fed electric power.
