A disk chucking device is provided to prevent an optical disk from separating from the disk chucking device and stably clamp the optical disk. A disk chucking device is integrated with a spindle motor(200) to prevent separation of an optical disk(10) when rotating the spindle motor at high speed. The spindle motor includes a base(210), a bearing holder(220), a bearing(230), an armature(240), a rotary shaft(250), and a rotor case(260). The base supports the spindle motor wholly. The bearing holder fixes the bearing. The armature includes a core(241) and a coil(242) wound on the core. A magnet(261) is fixed on the inner wall of the rotor case. The disk chucking device has a turn table(110), a housing(120), a chuck pin(130), a spring(140), and a supporting member. The turn table is formed with a combining holder(111) and a combining hole(112). The housing has a plurality of receiving holes(121) and a fixing projection(122) for fixing the spring. The receiving hole has inner walls(123) to cover the spring and the chuck pin. The supporting member supports the chuck pin to the opposite direction to the center of the optical disk.
