There is a problem that does not relieve the impact force.

Accordingly, the present invention has been devised to solve the above problems, and the present invention provides a multi-directional impact force generated by the collision even if the traveling vehicle collides in any direction with the guardrail installed near the road. It is an object of the present invention to provide a shock absorbing device for guard rails that effectively absorbs or disperses itself to minimize the loss of human and material due to collision.
