  In the routing member fixing body 100, the elastic piece 106 which constitutes the pressing portion 101 and is elastically supported by the inscribed holding portion 102 presses and fixes the routing member 1 to the inner peripheral surface of the corrugated tube 2 by elastic force. . Thereby, the routing material fixed body 100 can regulate the movement of the routing material 1 in the radial direction inside the corrugated tube 2. At this time, in the routing material fixed body 100, the inscribed holding portion 102 contacts the inner peripheral surface of the corrugated tube 2, and the inscribed holding portion 102 becomes the inner periphery of the corrugated tube 2 due to the reaction force of the elastic force of the elastic piece 106. By being pressed to the surface side, it is held and fixed by a frictional force or the like generated between the outer peripheral surface of the inscribed holding portion 102 and the inner peripheral surface of the corrugated tube 2. Thereby, the routing material fixing body 100 is positioned in the extending direction inside the corrugated tube 2 and can be made difficult to shift. Further, the routing material fixing body 100 has the circumscribed holding portion 103 in contact with the outer peripheral surface of the corrugated tube 2 and sandwiches the wall constituting the corrugated tube 2 between the inscribed holding portion 102 and the circumscribed holding portion 103. Hold this. Thereby, the routing material fixing body 100 can make it difficult to shift the relative positional relationship with the corrugated tube 2. Further, in the routing member fixing body 100, the connecting portion 104 passes through the slit 2a of the corrugated tube 2, and in other words, the connecting portion 104 is fitted into the slit 2a. Rotation in the circumferential direction can be restricted, in other words, positioning in the circumferential direction can be performed. The routing member fixing body 100 includes a pair of arm portions 105b of the clamp portion 105 inserted while being bent with respect to the fixing recess 50a, and each engaging step portion 105c is formed at the fixing portion 50 at the edge of the fixing recess 50a. As a result, the wiring member fixing body 100 can be locked and fixed to the fixing portion 50.

Movement in the direction can be restricted. At this time, the routing material fixed body 100 is held in contact with the inner surface of the corrugated tube 2 while the inscribed holding portion 102 is held in contact with the inner surface of the corrugated tube 2 and held in contact with the inner surface of the corrugated tube 2. By sandwiching and holding the wall constituting the corrugated tube 2 between the portion 103, the relative positional relationship between the routing member fixing body 100 and the corrugated tube 2 can be made difficult to shift. Therefore, it is possible to maintain a stable positional relationship and suppress the occurrence of rattling. In addition, the routing member fixing body 100 and the wire harness WH sandwich and hold the wall body constituting the corrugated tube 2 between the inscribed holding portion 102 and the circumscribed holding portion 103, thereby holding the corrugated tube 2. Can be prevented from opening from the slit 2a. And the routing material fixing body 100 is locked and fixed to the fixed portion 50 by the clamp portion 105 together with the routing material 1 and the corrugated tube 2, so that the routing material 1 and the corrugated material against vehicle vibration and the like.

Vibration can be suppressed more suitably. Moreover, as for the routing material fixing body 100 and the wire harness WH which were demonstrated above, the routing material 1 is comprised with the metal rod which a cross-sectional shape is comparatively hard to deform | transform compared with the electric wire etc. of a several core wire. Thus, for example, the pressing force by the pressing portion 101 can be appropriately applied to the routing material 1, and the routing material 1 can be more suitably fixed to the cylindrical corrugated tube 2. Moreover, since the wiring material fixing body 100 and the wire harness WH described above do not need to use, for example, a binding band or a winding tape to fix the wiring material 1, the corrugated tube 2 has a large diameter. In addition, the number of assembling steps can be reduced, and the manufacturing efficiency can be improved.
