Abstract
A method of manufacturing a resin spring which can improve close contact between a spring body and inner-pressure generating members to reduce variations in load characteristics due to repeated deformation during use. The method of manufacturing a resin spring includes the steps of forming an elastomer preform having inner closed chambers, inserting inner-pressure generating members into the inner closed chambers of the preform, and compressing the preform with the inner-pressure generating members therein by applying an external force to produce a permanently deformed portion having an oriented molecular structure.
