PROBLEM TO BE SOLVED: To provide a shock absorbing structure for a bridge, which is small in size, light in weight, simple in structure, has large absorption of compressed energy compared with resistance, is good in corrosion resistance, water resistance, weatherability, etc., commercially available on a maintenance-free basis not only for a bridge in an inland area but also for a bridge in a coastal zone or an ocean connecting bridge, and can prevent impact fracture of a superstructure or a lower structure of the bridge due to an earthquake, etc., or falling accidents of the superstructure, as far as possible. SOLUTION: The shock absorbing structure for the bridge is constructed by arranging the shock absorbing members between the superstructures forming the bridge, between the superstructure and the lower structure, between the lower structure having a bridge fall preventive wall and the superstructure, and at a jig connecting the superstructures together or the superstructure and the lower structure together. The shock absorbing member is a molded body which is molded of a material having a bending modulus of 200 kgf/cm<SP>2</SP>or more, and has a wall structure in a shock load direction.
