のトルクチエツカー。 An eccentric cam 2 is integrally and rotatably attached to a rotating shaft 1 having a direct rotation interlocking part 1A of a torque driver, and a cam follower 3 in contact with the circumferential surface of the rotating eccentric cam 2 is supported so as to be able to reciprocate along a fixed linear path. and a spring 4 that presses and biases the cam follower 3 against the circumferential surface of the eccentric cam 2.
is provided in a state where it can be expanded and contracted only in the direction along the linear movement path, and the maximum amount of rotation of the rotating shaft 1 against the biasing force of the spring 4 is at least equivalent to the maximum amount of rotation. A device 5 that detects torque in two stages: when the torque is within the set torque range and when it is not, and displays different lighting indications in each stage.
A torque checker for a torque screwdriver characterized by being equipped with.
