<P>PROBLEM TO BE SOLVED: To provide a cushion structure advantageous to improve the possibility of falling off of a sub elastic body from an insertion hole of a main elastic body while inhibiting separation of a fatigued outside wall surface of the sub elastic body which is caused by adhesive bonding and separation thereafter. <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, and the sub elastic bodies 3 each disposed in the insertion hole 23. The sub elastic body 3 has the outside wall surface 33 facing the inside wall surface 25 of the insertion hole 23, and is formed of an adhesive organic elastic material. A covering member 7 formed of an elastic organic foam material is provided to cover at least the outside wall surface 33 of the sub elastic body 3. The sub elastic body 3 is held in the insertion hole 23 by an adhesive layer 29 or frictional force between the inside wall surface 25 of the insertion hole 23 and the outside surface 7p of the covering member 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
