チの光フアイバ固定機構。 It is attached to a case that houses a printed wiring board with a light emitting element and a light receiving element arranged side by side facing the opening side, and an optical fiber is inserted toward the light emitting element and the light receiving element, and this optical fiber is fixed. An optical fiber fixing mechanism of an optical fiber type photoelectric switch equipped with a holder has an insertion hole through which the optical fiber is inserted and which guides the optical fiber to the light emitting element or the light receiving element. A fiber holder has a slit whose part gradually becomes thicker in the direction of the optical fiber insertion opening and vertically divides the thick part of the peripheral wall, and a through hole through which the fiber holder is slidably guided, and is attached to the case. A guide holder is attached to guide the fiber presser through the fiber presser, and a lever is supported by a fulcrum provided on the guide holder and has a spring that applies a reaction force to the force point thereof, and the fiber presser is attached to the action point of the lever. An optical fiber type photoelectric switch, characterized in that the optical fiber inserted into the insertion hole of the fiber holder is fixed by pressing the force point and tightening the fiber holder by sliding the fiber holder by the reaction force of the spring. Optical fiber fixing mechanism.
