The pelprene protective device which is made from polyester elastomer named pelprene was developed for one of protection system contacted with bridge and absorbed colliding energy by elastic deformation of the protection. In this paper authors studied on the effect of shock absorption of this protection system by model experiment. Collision experiment of the bow model to the pelprene protective device was executed. The following results are obtained : -The shock absorption efficiency are about 50%, energy absorption efficiency are about 60% in first collision. And in case of repeated collision, it slightly fall, but the shape is almost restore. -These characteristics do not change by collision point or a collision angle or a inclined angle of bow. -The load-penetration curb is nearly equal to result of static penetration test.
