Abstract
A manufacturing method for a code wheel for a rotary encoder is provided. The code wheel includes, in a central portion, a hole into which a rotary shaft of a rotary member is fitted and a code portion including a radial code pattern in a circumferential edge portion. The manufacturing method is configured to include the steps of forming the code portion and a reference circle in a plate so that the reference circle has a radius larger than a radius of the hole by a tolerance of deviation between a center position of the code portion and a center position of the hole and has a same center as that of the code portion; and forming the hole in the plate in which the code portion and the reference circle are formed, so as to be contained in the reference circle.
