PROBLEM TO BE SOLVED: To make it possible to set the optical fiber cord holder only by standing-2 rod-shaped core material on a wall surface and supporting a cylindrical elastic member on this rod-shaped core material. SOLUTION: The male screw part 42a of the rod-shaped core material 42 is engaged with a female screw hole 41 bored in the wall surface of a board 33 for cord holding, and the rod-shaped core material 42 is stood on the wall surface of the board 33. Cylindrical sponge 43 is inserted into the rod-shaped core material 41 and held. The optical cord holder 34 in this simple structure is easily fitted onto the wall surface only by standing the rod-shaped core material 42 and inserting the cylindrical sponge 43. When the optical fiber cord 44 can not be clamped between a couple of cylindrical sponges 43a and 43b, the optical fiber cord 33 which can not be clamped between one cylindrical sponge 43b and another cylindrical sponge 43c adjoining thereto can be clamped and many cords 44 can be held by using a small number of components. |
