もある。However, unless the outer diameter of the conduit and the inner diameter of the insertion hole are substantially the same, it is impossible to engage the outer peripheral surface of the conduit with the peripheral surface or end surface of the insertion hole. Therefore, there is only one type of conduit tube that can be connected to one insertion hole, although it has an outer diameter dimension that is substantially the same as the inner diameter of the insertion hole. This causes various complications during use. For example, when several types of conduits having different outer diameter dimensions are used, it is necessary to prepare some types of wiring boxes having insertion holes corresponding to those conduits. Also, when connecting a conduit to a wiring box using a connector, it is necessary to prepare several types of connectors corresponding to the diameter of the conduit.
