Abstract

A torque sensor is provided. The torque sensor includes: an output shaft; a stator holder into which the output shaft is inserted and coupled to the stator holder; a second coupling piece connected to the stator holder and configured to be in contact with an outer surface of the output shaft contact; and a through hole formed in the second coupling member in a circumferential direction, wherein a second arch ring is provided in the through hole to contract the second coupling member in a central direction.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 2012-0147301 filed on December 17, 2012, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] The present invention relates to a sensor, and in particular to a torque sensor. Background technique [0004] A power steering system for a vehicle is a system configured to smoothly steer a steering handle when frictional resistance applied to a steering wheel increases and thus a manipulation force for turning the steering handle also increases. [0005] Although a hydraulic power steering system using hydraulic pressure is used in the related art, a motor-operated power steering system using a rotational force of a motor is widely used in recent years. [0006] A motor-operated power steering system requires a torque sensor as disclosed in Korean Patent Laid-Open Publication No. 10-2009-000...
