In this paper, we derive the maximal subspace of positive numbers, for which the restricted maximal operator of Fej,r means in this subspace is bounded from the Hardy space H (p) to the space L (p) for all 0 < p a parts per thousand currency sign 1/2. Moreover, we prove that the result is in a sense sharp.
