PURPOSE: To provide a turn table device, in which a metal die structure can be simplified without using a resin alignment pawl and further, a leaf spring for applying elastic force in a disk alignment mechanism can be attached even after the shaft hole of a turn table is inserted in a motor shaft. CONSTITUTION: This turn table device has a motor having a protruded motor shaft 10a and a turn table 20 having a shaft hole 20a, in which the protruded portion of the motor shaft 10a is inserted and fitted, and a recess 21a for magnet housing formed in a central part 21 for disk hole fitting around this shaft hole, and a permanent magnet 23 for clamping an information storage disk placed on the turn table 20 is housed in the recess 21a for magnet housing. The disk alignment mechanism has a plurality of spring seat parts 25 accompanied with a spring oscillation space 25a formed at intervals in the circumferential direction of the central part 21 for disk hole fitting, and each of spring seat parts 25 is equipped with a leaf spring 26 for centering a little protruding a drooped piece 26d from an outer peripheral face 21b of the central part 21 for disk hole fitting to the outside of a diameter direction.
