AI Technical Summary
Technical Problem
Existing torque sensors using strain sensors face durability issues due to repeated stress, leading to potential fatigue failure.
Method used
A torque sensor design featuring a strain body with a protrusion that faces the inner surface of a housing in the radial direction, allowing for high sensitivity in stress detection while minimizing fatigue failure by distributing external forces effectively.
Benefits of technology
The design enhances durability by reducing fatigue failure and maintaining high sensitivity in stress detection, even under varying external forces.

Abstract
Provided is a durable torque sensor. A torque sensor (100, 200, 300, 400, 500, 600) comprises: a member (S) that is displaced in the axial direction; a strain-generating body (101, 201, 301, 401, 501, 601); and a housing (104) that accommodates the member (S) and the strain-generating body (101, 201, 301, 401, 501, 601). The strain-generating body (101, 201, 301, 401, 501, 601) is provided with a protrusion (111, 211, 311, 411) that protrudes in the axial direction. The protrusion (111, 211, 311, 411) faces an inner circumferential surface (104 ci) of the housing (104, 501, 601) in the radial direction.
