ABSTRACT:
A rotational speed detecting sensor includes a detecting portion having a detecting member provided facing a magnetized portion to be detected, the detecting portion for detecting variations of a magnetic flux generated by a rotation of the portion to be detected, a fix portion for fixing the detecting member, the fix portion being formed by means of molding and a case, a first end of which is closed and a second end of which is opened. The case includes a housing portion recessed toward the first end of the case from an opening portion side of the case, the housing portion for housing the detecting member, and a positioning portion for restricting a movement of the case in a mold in a direction toward the opening portion side of the case from the first end of the case.
