PROBLEM TO BE SOLVED: To provide a disk drive device having such a structure that a turn table is rotationally supported using a rotary shaft of a driving motor without affecting wobbling or the like and the deviation of the turn table to the side of the driving motor is reduced as little as possible when an external force such as a falling shock is applied. SOLUTION: The disk drive device is provided with: a turn table 10; a driving motor 20 including a rotary shaft 25 for rotationally supporting the turn table 10; and an optical pickup unit 30 used to read information from a recording disk DK set on the turn table 10. A supporting section 13 of the turn table 10 includes, at its tip, a stopper part 13a which closes an axial hole 14 and with which a communication hole 13b is formed for communicating the axial hole 14 and the outside, and the rotary shaft 25 is pressed into the axial hole 14 in a state of forming a first gapΔB between the tip of the rotary shaft 25 of the driving motor 20 and the stopper part 13a.
