Patent ID: 7320258

Claim:
An attaching structure of a rotation-detecting sensor, the attaching structure comprising: (a) a rotation-transferring medium; (b) a rotation-detecting sensor having: (b1) a detection portion that detects a variation in magnetic field due to the rotation of the rotation-transferring medium to convert the variation into an electric signal; and (b2) a main body having a plurality of side faces; (c) a flange that is provided at at least one side face of the main body of the rotation-detecting sensor; (d) an attaching member for the rotation-detecting sensor, the attaching member having an attaching hole into which the main body of the rotation-detecting sensor is inserted, concurrently with the flange being applied to the attaching member; and (e) a resin-molded body that: (e1) covers by resin molding at least one part of the flange and a part of the attaching member to embed them in the resin-molded body; and (e2) fixes the main body of the rotation-detecting sensor to the attaching member through the flange, wherein the attaching member further comprises, in addition to the attaching hole, at least one supporting hole through which the resin-molded body penetrates.
