Abstract: A torque wrench, including: a head region with a receiving opening; a bending-resistant shaft region adjoins the head region; a support formed on the shaft region; and an actuating lever including an elastically bendable portion and a handle. The receiving opening receives a screwing instrument and defines an axis of rotation. The actuating lever, in resting position, is spaced apart from the in the circumferential direction to the axis of rotation. If a screwing instrument is inserted into the opening, the actuating lever transmits a torque. The wrench has an indicator region, which the exerted torque can be read as a result of the deflection of the actuating lever. When a reference force is reached, the bending portion comes into contact with the support. When a force is applied, the bending portion can be in the tightening direction and the torque can be read in the region.
