Abstract

　外部からの水の浸入を防ぐシール性能に優れ、内部発熱や外部環境の温度変化による内部の熱歪み、および外力によってセンサ部品やその周辺回路部に損傷が生じず、しかも安価に製作できる回転検出センサを提供する。この回転検出センサＡは、車輪用軸受に取付けるセンサ固定部材７に固定され、車輪用軸受の回転輪の回転を検出するものである。回転輪の被検出体を検出する磁気式のセンサ素子１と、このセンサ素子１の出力信号を外部に取り出すケーブル１０と、センサ素子１およびケーブル１０の一端部が取付けられ、かつセンサ素子１の電極部２とケーブル１０の芯線４とを電気的に接続する導電部３を有する基板１１とでセンサユニットＢを構成する。このセンサユニットＢを基板１１でセンサ固定部材７に固定する。センサユニットＢの周囲に、熱可塑性エラストマまたはゴム材を成型してなるモールディング部８を設ける。
