It extends over the curved surface portions 10d and 10e. With this configuration, the protector 1 has various wiring materials W having different outer diameters and numbers depending on the binding member 101 inserted through the through hole 20, for example, in the range where the through hole 20 extends in the width direction X. Can be properly fixed to the main body 10.

For example, FIG. 3 illustrates a case where the wiring material Wmin having the smallest outer diameter among the wiring materials W expected to be inserted into the main body 10 is bound and fixed to the main body 10. In this case, the binding member 101 is wound around the wiring material W and the bottom portion 10a via the portion on the bottom penetration portion 20a side, which is a portion formed in the bottom portion 10a in each through hole 20, and the wiring material W and the bottom portion. It is possible to bind and fix the 10a to each other. On the other hand, FIG. 4 illustrates a case where the wiring material Wmax having the largest outer diameter among the wiring materials W expected to be inserted into the main body 10 is bound and fixed to the main body 10. In this case, the binding member 101 is wound around the wiring material W and the bottom portion 10a via a portion on the curved surface portion penetrating portion 20b side, which is a portion formed on the curved surface portion 10d and 10e in each through hole 20, and is routed.

It is possible to sufficiently secure the length of the portion wound around the material W. As a result, the protector 1 can surely bind and fix the wiring material W in any of the cases of FIGS. 3 and 4. It should be noted that FIGS. 3 and 4 illustrate variations in the binding mode due to the difference in the outer diameter of the wiring material W, but the present invention is not limited to this, and there are cases where the number of wiring materials W to be bound by the binding member 101 is different. The same is true.

Further, as described above, the protector 1 has a configuration in which each through hole 20 extends from the bottom portion 10a to the curved surface portion 10d and 10e side. With this configuration, for example, the protector 1 can secure an appropriate length as an interval between the through holes 20 along the width direction X without increasing the size of the main body portion 10 with respect to the width direction X. , It is possible to secure an appropriate strength against a load acting on a portion between the respective through holes 20. As a result, the protector 1 can be improved in versatility while suppressing the increase in size and ensuring appropriate strength.

Further, since the protector 1 has a configuration in which each through hole 20 extends from the bottom portion 10a to the curved surface portion 10d and 10e side, the tip of the binding member 101 is inserted when the binding member 101 is inserted into the through hole 20. The portion can be easily guided to the side wall portions 10b and 10c along the curved surface portions 10d and 10e. With this configuration, the protector 1 can improve the inducibility of the tip end portion of the binding member 101, so that the workability when binding and fixing the cording material W to the bottom portion 10a by the binding member 101 can be improved. ..
