ABSTRACT:
A potentiometer includes a pair of magnetic resistance effect elements which cooperate with a permanent magnet carried by a rotary shaft. The shaft is supported for angular movement by a cylindrical holder formed of synthetic resin material and disposed in partial surrounding relationship and in contact with the shaft. The holder includes a cylindrical reinforcing member of metallic material embedded therein and having an axis which is aligned with the axis of the rotary shaft. The member affords reinforcement to and prevents a distortion during molding of the holder.
