ABSTRACT:
A holding member for holding a magnetic sensor at a position opposed to a rotary magnetic scale for magnetic signal detection in a magnetic rotary encoder is made by first cutting from a metal or synthetic resin sheet a single sheet member having unique extensions, projections, holes or apertures along and near its outer margin, and subsequently bending the sheet member along predetermined lines to form a self-standing support body and use original cut margins of the extensions and projections as reference or guide surfaces which define proper contacting relationships with the magnetic sensor and with a base plate on which the holding member is fixed.
