PROBLEM TO BE SOLVED: To reduce the manufacturing cost by suppressing the component management cost and assembling cost in a structure capable of increasing the resolution of torque measurement.SOLUTION: An input gear 7b is externally engaged with and fixed to an axial intermediate part of an input-side unit 67 concentrically with the input-side unit 67 and rotatably synchronously with the input-side unit 67, thereby forming an input-side rotation body 55b. The input-side unit 67 is formed as an integral molded article by integrally forming an input shaft 13a, an inner ring 30c forming a conical roller bearing 29c for supporting the input shaft 13a rotatably with respect to a housing, and a torsion bar 15a. 【課題】トルク測定の分解能を高くできる構造に於いて、部品管理コストや組立コストを抑えて、製造コストの低減を図る。【解決手段】入力側ユニット６７の軸方向中間部に入力歯車７ｂを、この入力側ユニット６７と同心に、且つ、この入力側ユニット６７と同期した回転を可能に外嵌固定する事により、入力側回転体５５ｂを構成する。この入力側ユニット６７を、入力軸１３ａと、この入力軸１３ａをハウジングに対して回転自在に支持する円すいころ軸受２９ｃを構成する内輪３０ｃと、トーションバー１５ａとを一体に造った、一体成形品とする。【選択図】図１
