Document Type and Number:
WIPO Patent Application WO/2018/186466
Kind Code:
A1
Abstract:
A torque wrench capable of clamping a member to be clamped, at a predetermined torque, with a small number of components and a simple structure is provided at low cost while achieving reductions in size and weight. A simple torque wrench 1 is constituted of a socket 2, a lever 3, a support spring 4, an adjustment holder 5, and a cap 6 and is used to clamp a nut etc. at a predetermined torque. The socket 2 and the lever 3 are integrally held by each other, in a state in which the periphery of a ratchet part 2b and a columnar body 3a is surrounded by the support spring 4, thus making a swing piece 3b abut against the ratchet part 2b in a direction tangential to the outer shape of the ratchet part 2b. Furthermore, the adjustment holder 5 holds, at an arbitrary position, a sandwich section 4c of the support spring 4 that sandwiches both sides of the columnar body 3a in the width direction.
