<P>PROBLEM TO BE SOLVED: To provide a foamed rubber member which has low hardness and excellent durability. <P>SOLUTION: The foamed rubber member is produced through an impregnation treatment of a foamed elastic body with a treatment liquid containing an isocyanate compound and an organic solvent. The foamed elastic body produced by foaming a base rubber, exhibits a compression set smaller than that of the foamed elastic body before undergoing the impregnation treatment, and exhibits a percent increase in stress, with respect to the stress of the foamed elastic body before undergoing the impregnation treatment, of 50% or less. <P>COPYRIGHT: (C)2010,JPO&INPIT |
