ABSTRACT:
A corner pole device for vehicles comprises a drive mechanism by which a pole assembly vertically telescopically movable with respect to a housing thereof disposed at a corner part of a vehicle body is driven to expand and contract between an expanded position and a housed position. The corner pole device further comprises a control means for automatically controlling the drive mechanism to thereby drive the pole assembly into a telescopic action, depending on a detection signal from a mechanism which detects the travelling condition of vehicle.
