PROBLEM TO BE SOLVED: To provide a sensor unit which is capable of preventing or suppressing an influence of heat on a collector when a sensor housing receives the heat.SOLUTION: The sensor unit includes: a first collector 41 which is disposed to face a first stator for guiding a magnetic flux, across a space and thereby collects the magnetic flux guided by the first stator; a second collector 42 which is disposed to face a second stator across a space and thereby collects a magnetic flux guided by the second stator; and a sensor housing 46 which has a peripheral wall 46q (wall) formed therein to cover the outside of the first collector 41 and the second collector 42 and holds the first collector 41 and the second collector 42. A space K is formed between a surface 41B opposite to a surface 41A facing the first stator, of the first collector 41 as well as a surface 42B opposite to a surface 42A facing the second stator, of the second collector and the peripheral wall 46q of the sensor housing 46.

    【課題】センサハウジングが熱を受けてもコレクタに熱の影響が及ぶのを防止乃至抑制することができるセンサユニットを提供する。【解決手段】磁束を導く第1ステータとの間に空隙を介して対向して配置されることにより第1ステータで導かれた磁束を集磁する第1コレクタ41と、第2ステータとの間に空隙を介して対向して配置されることにより第2ステータで導かれた磁束を集磁する第2コレクタ42と、第1コレクタ41及び第2コレクタ42の外方を覆う周壁46q(壁)が形成され、第1コレクタ41及び第2コレクタ42を保持するセンサハウジング46とを備え、第1コレクタ41の第1ステータに対向する面41Aとは反対の面41B及び第2コレクタ42の第2ステータに対向する面42Aとは反対の面42Bと、センサハウジング46の周壁46qとの間に、隙間Kを形成した。【選択図】図4
