<P>PROBLEM TO BE SOLVED: To provide a cushion structure having high durability of a highly adhesive outside wall surface of a sub elastic body and advantageously extending its life. <P>SOLUTION: The cushion structure 1 has a main elastic body 2 having a plurality of insertion holes 23 each made of an organic elastic material and partitioned by an inside wall surface 25, and the sub elastic bodies 3 each disposed in the insertion hole 23 of the main elastic body 2. The sub elastic body 3 has the outside wall surface 33 facing the inside wall surface 25 of the insertion hole 23 through a space. The main elastic body 2 has deformation urging portions 4 each formed of a recess or cut, and the deformation urging portion is positioned outside the inside wall surface 25 of the insertion hole 23 relative to the axis 24 of the insertion hole 23. The deformation urging portion 4 increases following deformation of the inside wall surface 25 of the main elastic body 2 so that the adhesive contact between the inside wall surface 25 of the insertion hole 23 of the main elastic body 2 and the outside wall surface 33 of the sub elastic body 3 is allowed to be maintained upon restorative deformation caused by compressive deformation of the sub elastic body 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
