Claims

[Scope of utility model registration request]

A case for storing a printed wiring board in which a light emitting element and a light receiving element are arranged side by side with their openings facing each other, and an optical fiber that is press-fitted into the opening of the case and facing each of the light emitting element and the light receiving element. a holder provided with a possible through hole and a slit that crosses the through hole and is perpendicular to the direction in which the optical fibers are arranged;
A wire spring arranged to surround the outer periphery of the slit position of the holder and connected at both ends to a cam portion, and a lever that includes the cam portion and tightens the wire spring by rotating the cam portion so as to come into contact with the holder. An optical fiber fixing device for an optical fiber type photoelectric switch, comprising:
