ABSTRACT:
This clearance indicating device has a pivotal rod for contacting an automobile when the latter is driven close to a wall surface. The pivotal rod causes a sliding rod to slide upwards from a support frame. The closer the automobile is positioned to the wall surface the higher the sliding rod will extend upwards from the support frame. Two pivotally mounted cantilever arms are mounted on the support frame. The arms are connected to two ends of a sliding cord coupled to the sliding rod such that the arms will swing upwards in various degrees to indicate the closeness of the automobile to the vertical wall surface.
