PROBLEM TO BE SOLVED: To obtain a structure which can regulate a positional relationship between a sensor and an encoder by preventing the rotation of a sensor unit by the fastening torque of a bolt when fastening the bolt for fixing the sensor unit to a cap.SOLUTION: A cap-side engagement recess 39 is formed at an inside face of a cap bottom plate part 19b in an axial direction, and a holder-side engagement protrusion 41 is formed at an outside face of a holder main body 26a in the axial direction. Then, the sensor unit 22a is supported and fixed to a cap 18b with a bolt 29a in a state that the holder-side engagement protrusion 41 and the cap-side engagement recess 39 are irregularly engaged with each other, and the outside face of the holder main body 26a in the axial direction is made to abut on the inside face of the cap bottom plate part 19b in the axial direction.SELECTED DRAWING: Figure 1

    【課題】センサユニットをキャップに固定する為のボルトを締め付ける際、ボルトの締め付けトルクにより、センサユニットが回転する事を防止して、センサとエンコーダとの位置関係を規制できる構造を実現する。【解決手段】キャップ底板部19bの軸方向内側面に、キャップ側係合凹部39を形成する。又、ホルダ本体26aの軸方向外側面に、ホルダ側係合凸部41を形成する。そして、センサユニット22aを、ホルダ側係合凸部41とキャップ側係合凹部39とを凹凸係合させると共に、ホルダ本体26aの軸方向外側面を、キャップ底板部19bの軸方向内側面に当接させた状態で、ボルト29aによりキャップ18bに対して支持固定する。【選択図】図1
