A crosslinkable rubber composition containing a nitrile rubber (A) containing carboxyl groups with an iodine number of 120 or less, a polyamine crosslinking agent (B), and a basic crosslinking accelerator (C) which is expressed by the following general formula (1), in which the iodine number is determined according to JIS K6235. R1-NH-R2 (1) (where in the general formula (1), R1 and R2 are, respectively and independently, alkyl groups containing from 1 to 12 carbon atoms which may have substituents or cycloalkyl groups containing from 5 to 12 carbon atoms that may have substituents). |
