PROBLEM TO BE SOLVED: To allow a driver to reliably confirm the alighting request of a wheelchair passenger separately from that of a general passenger with a visual display by showing alighting signal displays in different modes via an alighting signal switch action for the general passenger and an alighting signal switch action for the wheelchair passenger. SOLUTION: A controller 20 arranged on a driver's seat is constituted of a first self-holding means 25 and a second self-holding means 30 connected in parallel with a main power supply via a series circuit of a limit switch 40 and a reset switch 35 provided at an entrance, contacts 26, 27, 28, 29 driven by the exciting coil 25a of the first self-holding means 25, and contacts 31, 32, 33 driven by the exciting coil 30a of the second self-holding means 30. Alighting request signals for a general passenger and a wheelchair passenger are shown in different modes, thus a driver can recognize the alighting request by the wheelchair passenger easily and reliably and assist the alighting of the wheelchair passenger reliably and quickly.
