A control rod drive device in which a drum wrapped with a wire rope suspending a control rod is rotated by a drive motor, and the control rod is inserted into and removed from a reactor core. A centrifugal brake is provided on a rotating shaft interlockingly connected to a drum shaft supporting the drum, and a centrifugal brake is provided to apply a braking force when the rotating shaft reaches a predetermined rotation speed, and a centrifugal brake is provided on a screw shaft interlockingly connected to the drum shaft. , a nut movable only in the axial direction is screwed together, and a buffer body is provided at the end of the screw shaft, with which the nut abuts and prevents movement when the control rod reaches a predetermined stopping position in the reactor core. A control rod drive device, characterized in that it is provided with a stopper member having a stopper member. 2. The control rod drive device according to claim 1, wherein the rotating shaft provided with the centrifugal brake is interlocked with the motor shaft of the drive motor via a gear system. 3. The control rod drive device according to claim 1, wherein the screw shaft is interlocked with the drum shaft via a gear device. 4. The control rod drive device according to claim 1, wherein the buffer is a spring such as a disc spring.
