The invention provides a shock absorbing device, comprising a top plate, a bottom plate and intermediate damping members arranged between the top plate and the bottom plate, wherein the intermediate damping members are capable of producing lateral horizontal movement and horizontal rotation along the top plate, and the intermediate damping members are connected with the bottom plate and are capable of producing lateral horizontal movement along the bottom plate. The intermediate damping members are uniformly arranged laterally along the top plate and the bottom plate, and each intermediate damping member comprises two arc-shaped steel structures that are symmetrically arranged and connected with each other into a whole. The shock absorbing device provided by the invention can adapt to thelateral seismic displacement of a bridge, provide additional damping dissipation input energy for the bridge and provide lateral yielding force for the bridge to prevent beam falling when meeting theearthquake or hurricane.
