PURPOSE:To facilitate positional adjustment of a detector by setting a detector for prevention of rear-end collision and a stop detector, vertically or horizontally back to back, in one box. CONSTITUTION:A front bumper supporting member 22a is fixed with a bracket 24 extending forward, and a box 25 incorporating a stop proximity switch 3 and a proximity switch 4 for prevention of rear-end collision vertically back to back with the proximity switch 3 directing up while furthermore incorporating a photoreceptor 5 for an optical switch is fixed to the tip of the bracket 24. A board 6 is fixed on a bumper supporting member 22b provided on the rear. The board 6 is detected for prevention of rear-end collision. The system is arranged such that the anti-rear-end collision proximity switch 4 of following electric vehicle faces with the upper side at the rear end of the board 6 when electric vehicles 1 approach closer than a predetermined distance and the proximity switch 4 detects the board 6. |
