摘要： PURPOSE: To maintain a function even for a high torque by limiting relative rotation with the use of a stopper where relative-rotating members hit each other and then allowing the relative rotation amount to correspond to maximum allowable material strength of a measurement device. CONSTITUTION: In order that slits 4a-4d which form members 5 and 6, relative rotation is possible, function as stoppers 5a and 8a which limit the relative rotation when the periphery surfaces facing each other at a boundary between the inside part 5 and the outside part 6 partially contact during relative rotation of both members, an extended form is provided. For this purpose, a slit width matches with the maximum allowable material strength of a measurement device, especially of spoke-like intermediate members 7a-7d and forklike arms 8a-8d. Thus, overload on the measurement device can be avoided, a torque can be transmitted even when the members 7a-7d or the arms 8a-8d are districted. This is because an engagement based on geometric form between the inside part 5 and the outside part 6 is maintained due to the extended form of the slits 4a-4d.

摘要： PURPOSE: To reduce the manufacturing cost, in particular the assembling cost, by forming the relatively rotatable members integrally with forked teeth and the forked handle part of a lever surrounding the members. CONSTITUTION: In order to take out the relative rotation members 1, 2 are coupled the forked teeth 4, 5 of a plurality of levers 6 disposed around the members 1, 2. The forked teeth 4, 5 are arranged in the axial direction and the forked levers 6 are extending substantially in the coupling direction. The forked handle part is coupled, at the end part thereof, with a detection ring 8 and a plurality of functional members can be assembled as one compositional member. Since the relatively rotatable members 1, 2 thus assembled can be coupled tightly with both forked teeth 4, 5, a parallel planar coupling face is not required. Furthermore, boring of the coupling hole, adjustment and assembling work can be eliminated.

摘要： PURPOSE: To obtain a torque measuring instrument which can be mass-produced at a lower manufacturing cost than the conventional measuring instrument. CONSTITUTION: A flexible body 50 is provided with adjacent parts in both the axial and radial directions. At the time of transmitting torque, the parts elastically rotate against each other and the relative rotation between the parts is converted into the amplified axial displacement of a ring 5 to be detected through an elastically displaced arm. The axial displacement is measured as the amount of transmitted torque. The arm is formed in the form of a fork and the fork tines 40a and 41a of the arm are respectively joined with the parts of the flexible body 50. The stem 43a of the fork is joined with the ring 5 to be detected. The flexible body 50, arm, and ring 5 are formed as punched members and at least the arm is additionally embossed. In addition, the arm is joined to the relatively rotating parts and ring 5.
