CONSTITUTION: A protection unit(20) is installed in the circumference of a bollard. The bollard is perpendicularly installed to the ground surface. A body part(21) of the bollard protects the bollard and a pedestrian. Wings of the bollard are horizontally formed in the body part to the ground surface.
