Zusammenfassung:A crosslinked rubber composition includes: a rubber component containing a first polymer which is an ethylene-α-olefin elastomer having an ethylene content of less than 60% by mass and a second polymer which is an ethylene-α-olefin elastomer having an ethylene content of 60% by mass or more; and short fibers dispersed in the rubber component. The rubber component is crosslinked by using organic peroxide as a crosslinking agent. The content of the organic peroxide in a not-yet crosslinked rubber composition is 1 part by mass or more and 10 parts by mass or less relative to 100 parts by mass of the rubber component.
