Claims

[Scope of utility model registration request]

One end of an optical fiber insertion hole in which an inner small diameter portion into which the exposed tip core portion of the sheathed optical fiber can be inserted and an outer large diameter portion into which the outer sheathing portion of the sheathed optical fiber can be inserted are continuous. a holder formed into a holder, a light emitting/receiving element embedded in the other end of the holder and facing the inner small diameter opening of the large hole for inserting the optical fiber, and a front end with a rear end fixed to the outer skin of the outer coated optical fiber. and a tension coil spring which is fixed to the inner end of the outer large diameter part of the optical fiber insertion hole, is fitted around the sheathed optical fiber, and press-fits the sheathed optical fiber into the optical fiber insertion hole.
