One axial end surface of the motor is brought into close contact with the motor mounting surface of a board, and the motor is fixed to the board with a mounting screw that is rotated from the side of the board opposite to the motor mounting surface, The rotary shaft is made to protrude toward the side opposite to the motor mounting surface of the board, a turntable is fixed to the rotary shaft, and a clamper is held on a holding plate that is movable in the axial direction of the rotary shaft, so that the clamper is fixed to the rotary shaft. In a rotation drive mechanism for a disk-type recording medium, the turntable is press-fitted and fixed to the rotation shaft, and the disk-type recording medium is sandwiched between the turntable and the clamper and rotated. The substrate is provided with a rotating shaft guide groove for introducing the rotating shaft to a predetermined mounting position in a direction parallel to the motor mounting surface, and the turntable and clamper are provided with a tool for rotating the mounting screw. A rotational drive mechanism for a disk-type recording medium, characterized in that a tool insertion opening is provided through which the tool is inserted in parallel with the axial direction of the rotating shaft. 2. The rotational drive mechanism for a disk-type recording medium according to claim 1, wherein the guide groove has a width larger than the diameter of the turntable and communicates with a pick-up conduction opening provided in the substrate. .
