PROBLEM TO BE SOLVED: To provide a Czochralski method single crystal ingot production device capable of stably producing the single crystal ingot without being affected by the irregular elongation of a wire and the shifted hooked position of a holder. SOLUTION: In this device for producing the ingot of a single crystal 1 by Czochralski method, a hooking step portion 1a of the single crystal 1 during its production by Czochralski method is hooked with a holder 50 and then pulled. Therein, a flexible mechanism for absorbing the irregular elongation of a wire 4, etc., is attached to the middle portion of the wire 4, and the irregular elongation of the wires 4, etc., are absorbed with the flexible mechanism.
