To provide a rotation detector enabling suppression of occurrence of incorrect assembly of a joint part.SOLUTION: A rotation detector includes: a frame body 25 which rotates integrally with a rotation axis; and a gear part 40 attached to the outer periphery of the frame body 25. Between the frame body 25 and the gear part 40, a joint part 51 is provided, which absorbs eccentricity of both. In the joint part 51 formed in an annual shape, a projection 61 is formed, which protrudes in the radial direction. The frame body 25 forms a rib 62 along the joint part 51. A portion opposite to the projection 61 of the rib 62 is provided with the recess 63 in which the rib 62 is cut out. A positioning mechanism 60 for positioning the frame body 25 and the joint portion 51 is configured by engaging the projection 61 and the recess 63.SELECTED DRAWING: Figure 4

    【課題】継手部の誤組付け発生を抑制可能にした回転検出装置を提供する。【解決手段】回転検出装置は、回転軸と一体に回転するフレーム体25とフレーム体25の外周に取り付けられたギヤ部40とを備える。フレーム体25とギヤ部40との間には、両者の偏心を吸収する継手部51を備える。環状に形成された継手部51は、半径方向に突出した突部61が形成される。フレーム体25は、継手部51に沿うようにリブ62を形成する。リブ62の突部61に対向する部分には、リブ62が切り欠かれた凹部63を備える。突部61及び凹部63が係合することで、フレーム体25と継手部51とを位置決めする位置決め機構60が構成される。【選択図】図4
