Zusammenfassung:	Provided is a self-sealable rubber composition, which shows self-sealability upon leakage of fuel, and thus prevents fuel leakage in a fuel tank when the fuel tank is damaged by external impacts. The self-sealable rubber composition comprises: 100 parts by weight of natural rubber; 10-30 parts by weight of a softening agent; 10-30 parts by weight of an inorganic filler; 0.5-10 parts by weight of a crosslinking agent; 0.5-3.5 parts by weight of a vulcanizing agent; and 10-20 parts by weight of a foaming agent. The inorganic filler includes carbon black. The softening agent is selected from the group consisting of naphthene oil, aromatic oil and paraffin oil.
