Corrugated tube-mounting structure

1. A method of mounting a corrugated tube onto a panel body, comprising the steps of:

providing a corrugated tube, including:

a tubular body, formed with a slit extending in an axial direction of the tubular body;

a plurality of ridge portions, formed on an outer periphery of the tubular body and arranged side by side in the axial direction; and

a lap portion, protruded from one of opposed end portions of the tubular body which are separated by the slit and extended toward an inner face of the other opposed end portion of the tubular body;

providing fixation members on the outer periphery of the tubular body;

twisting the tubular body such that the slit is spirally extended;

bending the twisted tubular body; and

attaching the fixation members onto the panel body while the corrugated tube is bent.

2. The mounting method as set forth in claim 1 , further comprising a step of fixing the twisted tubular body with electric wires inserted into the tubular body, before the bending step.

3. The mounting method as set forth in claim 1 , wherein:

each fixation member includes a clip member fixed on the panel body;

the respective clip members are oriented to different circumferential directions with respect to the tubular body, when the fixation members are provided; and

the tubular body is so twisted that the respective clip members are oriented to an identical circumferential direction.
