PURPOSE: A median strip of an impact suction equipment is provided to absorb an impact-induced injury stepwise in a collision of a vehicle by employing an impact suction equipment in a space of a round rail integral with a guide rail. CONSTITUTION: In a head-on or side collision of a vehicle to a median strip, a bumper of the vehicle hits the curved surface of a round rail. The impact is absorbed through an inner space portion depending on the impact degree of the round rail. The round rail is distorted during passing through an absorbing zone to reduce the impact force and pushed inward. The continuous impact force is transferred to a contact portion between shock absorbing bumpers(40,40') to be reduced secondarily. The secondary impact force is reduced suddenly by the shock absorbing bumpers(40,40') and a fine rest impact force is transferred to a post.
