ともに、コスト上昇の原因になっていた。By the way, in the case of the tray 7 as described above, the following problems occur due to the structure in which the pressing member 15 presses and holds the tube 10. That is, in order to obtain sufficient frictional resistance between the pressing member 15 and the surface of the tube 10, it is necessary to increase the pressure contact force of the pressing member 15 with respect to the tube 10. However, when the pressure contact force increases, stress is applied to the tape core wire 4. In addition, the transmission loss of the optical signal may increase. Conversely, if the pressure contact force is weak, it will be difficult to obtain sufficient frictional resistance,
The tube 10 is easily removed. In order to provide the pressing member 15 that can obtain an appropriate pressure contact force, it is necessary to manufacture various kinds of pressing members 15 in accordance with the diameter of the tube 10, the tensile force acting on the tube 10, etc. However, there is a problem that the cost increases. Further, since the pressing member 15 is a separate member from the tray 7, it takes time and labor to attach the pressing member 15 to the tray 7 and causes a cost increase.

が増大して、保持力が一層強化される。The operation and effect of the tray 20 will be described below. The tray 20 can regulate the movement of the tube 32 in the axial direction without applying stress to the tape core wire 4 by inserting and clamping the end of the tube 32 covering the tape core wire 4 into the holding groove 33. It is like this. That is, the tube 32 inserted into the holding groove 33
Is bent at three points by the bulging portion 35 and the contact protrusion 36, and therefore the tensile force acting in the axial direction of the tube 32 acts on the bulging portion 35 and the contact protrusion 36 in the axial direction to be supported. It As a result, a sufficient holding force is obtained even when the clamping force between the bulging portion 35 and the contact protrusion 36 is small, and the movement of the tube 32 in the axial direction is restricted. When the small protrusion 39 is provided on the contact surfaces 37 and 38 of the bulging portion 35 and the contact protrusion 36, the bulging portion 3
5, the frictional resistance of the tube 32 against the contact projection 36 is increased, and the holding force is further strengthened.
