To provide a yoke member for torque detection device capable of suppressing detection accuracy deteriorating when constituting a torque detection device.SOLUTION: A yoke member for torque detection device includes: a first yoke part 310 having a ring-like first ring plate part 311, and a plurality of first tooth parts 312 arranged at an equal interval on an inner edge part side of the first ring plate part 311; and a second yoke part 320 having a ring-like second ring plate part 321, and a plurality of second tooth parts 322 arranged at an equal interval on an inner edge part side of the second ring plate part 321. Then, the first yoke part 310 is constituted in such a manner that, in the array direction of the first yoke part 310 and the second yoke part 320, a maximum width L1 of the longest portion in the first tooth part 312 is narrower than a minimum width L2 between the inner edge part side and an outer edge part side in the first ring plate part 311, and the second yoke part 320 is constituted in such a manner that, in the array direction, the maximum width L1 of the longest portion in the second tooth part 322 is narrower than the minimum width L2 between the inner edge part side and the outer edge part side in the second ring plate part 321.SELECTED DRAWING: Figure 4C

    【課題】トルク検出装置を構成した際に検出精度が低下することを抑制できるトルク検出装置用ヨーク部材を提供する。【解決手段】リング状の第1リング板部311と、第1リング板部311の内縁部側に等間隔で配置された複数の第1歯部312と、を有する第1ヨーク部310と、リング状の第2リング板部321と、第2リング板部321の内縁部側に等間隔で配置された複数の第2歯部322と、を有する第2ヨーク部320と、を備える。そして、第1ヨーク部310は、第1ヨーク部310と第2ヨーク部320との配列方向において、第1歯部312における最も長い部分の最大幅L1が、第1リング板部311における内縁部側と外縁部側との間の最小幅L2よりも狭くなるようにし、第2ヨーク部320は、配列方向において、第2歯部322における最も長い部分の最大幅L1が、第2リング板部321における内縁部側と外縁部側との間の最小幅L2よりも狭くなるようにする。【選択図】図4C
