Claims

[Scope of utility model registration request]

A detection unit having an actuator, a photoelectric switch having a light emitter and a light receiver, a light emission fiber that guides light from the light emitter to the detection unit, and a light reception optical fiber that guides light from the detection unit to the light receiver. A limit switch comprising an optical fiber bundle, wherein a rotating piece that rotates according to the movement of the actuator is provided inside the detection section, and a reflecting surface of the rotating piece bends as the rotating piece rotates. A limit switch whose end portion is movable from a position parallel to the end face of the optical fiber bundle to a position inclined to the end face of the optical fiber bundle.
