気デイスク体。 An annular metal plate that supports a magnetic disk and a hub attached along the inner peripheral edge thereof, and a pair of grooves that are fitted into 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 having a flat spring having a bent portion at the lower end facing the flat wall side, the flat wall has a first flat protrusion in the vertical direction that intersects in a cross shape at approximately the center in the horizontal direction, and a horizontal first flat protrusion in the horizontal direction. forming second flat protrusions in the respective directions, and making the protrusion dimension of the first flat protrusion smaller than the protrusion dimension of the second flat protrusion, and the protrusion dimension of the second flat protrusion and the above from the gap dimension of the groove. A magnetic disk body characterized in that the difference between the width of the bent portion minus the additional dimension is smaller than the thickness of the leaf spring.
