する磁気デイスク体。 An annular metal plate supporting a magnetic disk and a hub attached along the inner peripheral edge thereof, and a pair of grooves provided on both sides of a flat wall forming a part of the peripheral wall of the shaft hole of the hub. In addition, in the magnetic disk body comprising a plate spring having a bent portion toward the flat wall at the lower end, a flat protrusion having a wide T-shape in front is formed approximately in the center of the flat wall; The difference obtained by subtracting the additional dimension of the protrusion dimension of the protrusion and the width dimension of the bent part from the gap dimension of the groove,
A magnetic disk body characterized in that the thickness is smaller than the thickness of the above-mentioned leaf spring.
