Claims

[Scope of Claim for Utility Model Registration] (1) A head portion that is swingable around a pivot center provided within the wrench body, and an end portion of the head portion that is located within the wrench body across the pivot center. a magnetic force sensitive part arranged in the wrench body at a position facing the magnetic force sensitive part of the head part and capable of sliding in the longitudinal direction of the head part; The torque screws are arranged in parallel, one longitudinal end of which is fitted to one longitudinal end of the magnetic body, and the other longitudinal end of which is exposed outside the wrench body, and which can be rotated from outside the wrench body. an adjusting member, wherein the torque adjusting member slides the magnetic body so as to change the length of the head portion facing the magnetic force sensing portion when rotated. (2) a rotatable head mounting shaft with one axial end located within the wrench body; a torque adjustment moving body that fits into one axial end of the head mounting shaft and is movable in the coaxial direction; At the other axial end of the torque adjustment moving body, one longitudinal end is attached to the center line of the head mounting shaft, and the other longitudinal end is provided so as to be exposed outside the wrench body. and a magnetic body disposed in a position in the wrench body that can face the torque adjusting moving body, and the torque adjusting member is configured to apply the torque to the magnetic body by rotating the wrench body from outside the wrench body. A torque wrench characterized by changing the facing length of the adjustment moving body.
