An anti-vibration rubber of the present invention is an anti-vibration rubber for washing machines. In temperature variance measurement of dynamic viscoelasticity at a frequency of 10 Hz, the anti-vibration rubber has a maximum loss factor at a temperature of 0° C. to 40° C., both inclusive, and has a loss factor of 0.5 or more in the entire temperature range of 0° C. to 40° C., both inclusive, at the frequency of 10 Hz.
