PROBLEM TO BE SOLVED: To provide a torque detecting device capable of suppressing the entry of static electricity into the inside of a magnetism collecting holder, and an electric power steering device including the torque detecting device.SOLUTION: A magnetism collecting unit 70 comprises magnetism collecting rings 71a and 71b, a first magnetism collecting holder 72a holding the magnetism collecting ring 71a, a second magnetism collecting holder 72b holding the magnetism collecting ring 71b, and a magnetic shield 80 covering outer peripheries of the magnetism collecting rings 71a and 71b. A recess 78 is provided on an inner peripheral surface of the first magnetism collecting holder 72a. An engaging protrusion 77 inserted into the recess 78 is provided on an outer peripheral surface of the second magnetism collecting holder 72b. A recess 101 is provided on an inner peripheral surface of the second magnetism collecting holder 72b. A protrusion 100 protruding toward the second magnetism collecting holder 72b is provided on the inner peripheral surface of the first magnetism collecting holder 72a. When the first magnetism collecting holder 72a and the second magnetism collecting holder 72b are assembled, the protrusion 100 is inserted into the recess 101.SELECTED DRAWING: Figure 3

    【課題】集磁ホルダの内側に静電気が侵入することを抑制することができるトルク検出装置およびこのトルク検出装置を備える電動パワーステアリング装置を提供する。【解決手段】集磁ユニット70は、集磁リング71a,71bと、集磁リング71a,71bをそれぞれ保持する第1の集磁ホルダ72aおよび第2の集磁ホルダ72bと、集磁リング71a,71bの外周とを覆う磁気シールド80とを備えている。第1の集磁ホルダ72aの内周面には凹部78が設けられている。第2の集磁ホルダ72bの外周面には凹部78に挿入される係合突起77が設けられている。第2の集磁ホルダ72bの内周面には凹部101が設けられている。第1の集磁ホルダ72aの内周面には第2の集磁ホルダ72bに向かって突出した突起100が設けられている。第1の集磁ホルダ72aおよび第2の集磁ホルダ72bが組み付けられたとき、凹部101には突起100が挿入される。【選択図】図3
