    摘要: A marker for road surfaces is of the type having a mounting adapted to be fixed in the roadway with an aperture at the upper end of the mounting for holding a visible portion held in upraised position by spring means; in the marker of the invention the visible portion is at least one reflector and/or light source, enclosed in a translucent sealed casing which is shaped to move vertically within the mounting.Preferably the visible portion is a pair of corner-cube reflectors, the mounting around the aperture contacts the casing so as to wipe its faces clean, and the spring means is a solid rubber ball.
