Claims

[Scope of utility model registration request]

In an optical fiber terminal structure in which a core holder is fitted to the end of the optical fiber and a base holder is further fitted, the core holder has a cylindrical body extending from the head to a rear position, and its axis A hole is provided along the cylindrical body into which the optical fiber is inserted, and the peripheral surface of the cylindrical body is cut in the axial direction so that the free end faces the rear position of the head, and an engaging protrusion is provided on the inside and an engaging protrusion is provided on the outside. The base holder includes at least one elastic engagement piece having a mating portion, and the base holder has a hole into which the core holder is inserted, and an engagement portion that complementarily engages with the engagement portion of the elastic engagement piece. An optical fiber terminal structure characterized by comprising:
