Abstract

A structure for attaching a band clip to a corrugated tube, provided with: a corrugated tube that has a plurality of ring-shaped ribs and a plurality of ring-shaped grooves, and that is for enclosing a wire harness; and a band clip for fixing the corrugated tube to an attachment target object. The band clip has a projecting portion that projects toward an outer circumferential surface of the corrugated tube when the band clip is attached to the corrugated tube. The corrugated tube has: a groove-shaped ring-shaped recessed portion into which the projecting portion is fittable; and a plurality of protruding portions that are provided at predetermined intervals in a circumferential direction of the ring-shaped recessed portion, and that are engageable with the projecting portion.

First claim

1 . A structure for attaching a band clip to a corrugated tube, comprising:
a corrugated tube that has a plurality of ring-shaped ribs and a plurality of ring-shaped grooves, and that is for enclosing a wire harness; and a band clip for fixing the corrugated tube to an attachment target object, wherein the band clip has a projecting portion that projects toward an outer circumferential surface of the corrugated tube when the band clip is attached to the corrugated tube, the corrugated tube has: a groove-shaped ring-shaped recessed portion that is provided in parallel with the ring-shaped grooves and into which the projecting portion is fittable; and a plurality of protruding portions that are provided at predetermined intervals in a circumferential direction of the ring-shaped recessed portion, and that are engageable with the projecting portion, and when the band clip is rotated in the circumferential direction relative to the corrugated tube, rotation of the projecting portion is restricted within any of the predetermined intervals, so that a range of rotation of the band clip is limited.

2 . The structure for attaching a band clip to a corrugated tube according to claim 1 , wherein
the ring-shaped grooves, the projecting portion, and the ring-shaped recessed portion are formed such that a relationship W 1 <W 2 <W 3 is satisfied, where W 1 denotes widths of the ring-shaped grooves in an axial direction that is orthogonal to the circumferential direction, W 2 denotes a width of the projecting portion in the axial direction, and W 3 denotes a width of the ring-shaped recessed portion in the axial direction.

3 . The structure for attaching a band clip to a corrugated tube according to claim 1 , wherein:
widths of the protruding portions in an axial direction that is orthogonal to the circumferential direction are set to be smaller than a width of the ring-shaped recessed portion in the axial direction.

4 . The structure for attaching a band clip to a corrugated tube according to claim 2 , wherein:
widths of the protruding portions in the axial direction are set to be smaller than widths of the ring-shaped grooves in the axial direction.
