The dynamical structure factor S(q, ω) of Heisenberg antiferromagnets with random fractal structures is investigated in terms of a dynamical scaling argument. It is found that the asymptotic behavior of S(q, ω) can be characterized by the dynamic exponent za and a new exponent y. We have performed numerical calculations of S(q, ω) in order to confirm its predicted scaling behaviors for d=2 percolating antiferromagnets. The calculated values for the exponents y and za are consistent with our theoretical prediction.
