PROBLEM TO BE SOLVED: To provide a shock absorber for floor and floor structure using it capable of improving defects in quality of conventional shock absorber for floor and floor structure using it and holding the same elastic force by components made of rubber or elastic resin by extrusion molding to reduce its price. SOLUTION: This shock absorber A for floor is constituted by forming tunnel-like hollow parts 2 arranged between a finish material 10 and a floor substrate 20 and forming substantially closed cross section in a base part 1 like a flat plate in a row integrally and forming at least one protruding bar 3 in the hollow part 2 along the hollow part 2 integrally. Usually, the hollow part 2 has a flat surface 2a being parallel with the base part 1. COPYRIGHT: (C)2008,JPO&INPIT
