Claim:
A crosslinkable rubber composition, which is crosslinkable by hot air and has the following properties: a crosslinked rubber sheet obtained by molding said rubber composition into a sheet and then subjecting the sheet to hot-air crosslinking has no scratch on the surface in a pencil hardness test using a pencil of HB and has a compression set (CS) of not more than 70% after a heat treatment at 150° C. for 22 hours, and further comprises: an ethylene/α-olefin/non-conjugated polyene random copolymer rubber (A) having constituent units derived from at least one kind of a vinyl end group-containing norbornene compound represented by the following formula (I) or (II), said norbornene compound being the non-conjugated polyene, and a SiH group-containing compound (B) having at least two SiH groups in one molecule; wherein n is an integer of 0 to 10, R 1 is a hydrogen atom or an alkyl group of 1 to 10 carbon atoms, and R 2 is a hydrogen atom or an alkyl group of 1 to 5 carbon atoms; wherein R 3 is a hydrogen atom or an alkyl group of 1 to 10 carbon atoms.
