ンコーダ。 Pulses are generated by a first code plate and a second code plate that are arranged coaxially and oppositely to each other so as to be relatively rotatable, and a light receiving and emitting element that is arranged opposite to the second code plate. A signal generating section is formed, a click mechanism is formed by an unevenness provided on the outer peripheral edge of the first code plate, and a roller that can engage with the unevenness, and the roller is brought into contact with the unevenness. In the optical rotary encoder, the roller and the shaft of the roller are integrally formed of synthetic resin, and the support member is formed of synthetic resin, and the roller and the shaft of the roller are integrally formed of synthetic resin. An optical rotary encoder characterized in that a support member is provided with a notch that can hold the shaft.
