Abstract
A corrugated tube made of resin includes outer grooved portions and outer ridged portions which are formed in a circumferential direction when the corrugated tube is seen from the outside. The outer grooved portions and the outer ridged portions continuously alternate in a tube-axial direction. Inner ridged portions and inner grooved portions are formed on an inner surface of the corrugated tube so as to respectively conform to the shapes of the outer grooved portions and the outer ridged portions. A cushioning portion is formed on the inner surface of the corrugated tube, and has hardness softer than that of a covering outer surface of one or multiple conductive paths accommodated in the corrugated tube.
Claims6
A corrugated tube which is made of resin, and is formed into a shape in which, when the corrugated tube is seen from the outside, outer grooved portions and outer ridged portions are provided in a circumferential direction, the outer grooved portions and the outer ridged portions continuously alternate in a tube-axial direction, and inner ridged portions and inner grooved portions are formed on an inner surface of the corrugated tube so as to respectively conform to shapes of the outer grooved portions and the outer ridged portions, the corrugated tube comprising:
- cushioning portions formed in apex portions of the respective inner ridged portions, wherein each of the cushioning portions has a hardness softer than a hardness of a covering outer surface of one or multiple conductive paths accommodated in the corrugated tube.
