摘要： PROBLEM TO BE SOLVED: To provide a torque wrench capable of discriminating whether the torque wrench is fastened by a preset torque value or overtorque.
SOLUTION: This torque tool has a sensor for measuring fastening torque of a bolt, a toggle mechanism, and a Hall element of trapezoidally changing output voltage by a change in a distance with a permanent magnet moved in response to operation of the toggle mechanism. The torque tool sets an operation position of toggle in an increase area of the output voltage; sets a reduction area of the output voltage in a position after generating the overtorque; sets a first switch point SP1 in a position delayed more than the operation timing of the toggle in the voltage increase area; selectably sets a second switch point SP2 in a position after generating the overtorque in the reduction area of the output voltage; and determines a maximum peak value in peak values of torque arithmetically operated on the basis of a signal from the sensor up to reaching the selected switch point, to be displayed on a display means.

摘要： PROBLEM TO BE SOLVED: To provide a torque measuring instrument of a digital type which includes a torque sensor being small-sized and lightweight, having a reduced thickness and designed for electrically measuring a minute torque.
SOLUTION: The torque sensor 1 is composed of a strain body 2 formed of a strip-shaped metal member of which either end is made a central end and the other an outer end and which is formed in the shape of a single-fold coil around the central end so that a plane part is formed at an arbitrary position of the metal member, and a strain gage 14 disposed on either or both of surfaces of the strain body. In the case when the torque in the coiling direction of the coil-shaped strain body is inputted to the body and the body is deformed relatively in the direction of coiling in or opening, a strain caused in the surface of the strain body is detected and thereby the inputted torque can be measured. By using the torque measuring instrument equipped with this sensor, the torque can be measured accurately by the lightweight and small-sized sensor.

摘要： PROBLEM TO BE SOLVED: To provide an automatic transmission device capable of performing a speed change switching operation according to load variation only by a mechanical mechanism.SOLUTION: The automatic transmission device includes a first clutch F1, a second clutch F2, and a speed-changing torque detection section E. The first clutch F1 performs switching between an ON state for transferring rotation of a drive motor B to the cage C3 of a planetary gear mechanism C and an OFF state for cutting off the transfer of the rotation. The second clutch F2 performs switching between an OFF state for freely rotating a ring gear C4 by bringing a non-rotary speed-changing member D2 and a ring gear C4 into a non-connected state and an ON state for connecting and integrating the speed-changing member and the ring gear in predetermined timing by making the speed-changing member and the ring gear wait in a neutral state where they can be connected. The speed-changing torque detection section E performs switching operations on the first and second clutches by moving clutch operating sections (E2, E5) from a first position of low torque detection to a second position of high torque detection when a gear shifting torque value for a speed change is detected based on the load of a drive target G. In the first position state of the clutch operating section, the first clutch is turned ON and the second clutch is turned OFF. In a second position state of the clutch operating section, the first clutch is turned OFF and the second clutch is turned ON.
