The present invention provides an easy-of-use torque calibration device capable of improving workability and safety and attaining reduction in time of a torque calibration in calibrating a torque of a dynamometer. That is, the present invention includes a connecting shaft 2 coaxially connected to a torque measurement rotor D1, a calibration arm 3 integrally rotated with the connecting shaft 2, a plurality of calibration weights 61 for applying loads to both ends of the calibration arm 3, a moving mechanism 4 to move the connecting shaft 2 between a connection position P and a spaced position Q, and a rotating direction fixing mechanism 5 for fixing the torque measurement rotor D1 and the connecting shaft 2 in the rotating direction at the connection position P, and a control unit 9 controlling the moving mechanism 4.
