<P>PROBLEM TO BE SOLVED: To provide a safety guide sign elastically recovered without breaking when colliding with or coming into contact with an automobile, a person, a cart or other objects, and returned into the original position. <P>SOLUTION: A pole for identifying a lane and a road zone is made of rubber. Resilient balls are inserted in a hollow of the pole so as to quickly return into the original state when bent, and work of installing the pole can be simultaneously performed while solidifying the ground to the soft ground surface so that the pole does not come off the ground surface caused by impact. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
