Patent ID: 7692095

Claim:
A wire harness lead-out structure, comprising: a body that includes a containing portion for receiving a wire harness and a corrugated tube covering the wire harness; a lid that is attached to the body to close an upper opening of the body; two completely-fixing ribs that are formed on the body and the lid respectively to be engaged in grooves of the corrugated tube to prevent a movement of the corrugated tube in an axial direction of the corrugated tube; and a provisionally-fixing rib that is formed in a single line on the opposed side walls of the body to be engaged in a single groove of the corrugated tube, and is disposed between the two completely-fixing ribs, wherein the completely-fixing ribs are arranged in two lines corresponding to two grooves of the corrugated tube, the two grooves being both adjacent to the single groove corresponding to the provisionally-fixing rib; wherein each of the completely-fixing ribs on the body is formed into a U-shape along an inner periphery of the containing portion so that a distance between upper portions of the completely-fixing rib respectively formed on opposed side walls of the body is constant; wherein a distance between portions of the provisionally-fixing rib formed on the opposed side walls is gradually decreased toward the upper opening of the body to prevent the corrugated tube from moving toward the upper opening of the body when the provisionally-fixing rib is engaged in the single groove of the corrugated tube; wherein a first pair of pressing walls is provided among the provisionally-fixing rib and one completely-fixing rib to press a ridge of the corrugated tube, the ridge being disposed adjacent to the grooves corresponding to the one completely-fixing rib; wherein a second pair of pressing walls is provided among the provisionally-fixing rib and the other completely-fixing rib to press a ridge of the corrugated tube, the ridge being disposed adjacent to the groove corresponding to the other completely-fixing rib; and wherein a distance between portions of each pair of pressing walls formed respectively on the opposed side walls is gradually decreased toward the upper opening of the body to prevent the corrugated tube from moving toward the upper opening of the body when the pressing walls press the ridges of the corrugated tube.
