Abstract

A tubular outer member which houses and protects a conductive path, the tubular outer member includes a fixing member mounting portion in which a conductive path fixing member is to be mounted so as to fix the conductive path. The fixing member mounting portion includes a guide groove configured to guide a conductive path winding portion of the conductive path fixing member extending like a line or a belt, and a pair of lead-in/out portions. The conductive path winding portion is to be inserted to and pulled out from the pair of lead-in/out portions.

First claim

What is claimed is:

1. A tubular outer member which houses and protects a conductive path, the tubular outer member comprising:
a fixing member mounting portion in which a conductive path fixing member is to be mounted so as to fix the conductive path;
wherein the fixing member mounting portion comprises:
a guide groove configured to guide a conductive path winding portion of the conductive path fixing member extending like a line or a belt; and,
a pair of lead-in/out portions, wherein the conductive path winding portion is to be inserted to and pulled out from the pair of lead-in/out portions,

wherein an inner surface of the outer member is shallowly recessed at the guide groove, and the guide groove extends in a circumferential direction,
wherein the guide groove is recessed in a valley-like shape at each of the pair of lead-in/out portions when viewed from inside of the outer member, and an outer surface of the outer member is protruded in a mountain-like shape at the each of the pair of lead-in/out portions when viewed from outside of the outer member, and
wherein the each of the pair of lead-in/out portions includes a lead-in/out opening for the conductive path winding portion, which is located on an inside bottom of the lead in/out portion when viewed from the inside of the outer member and an outside top of the lead in/out portion when viewed from the outside of the outer member.

2. The tubular outer member according to claim 1 ,
wherein valley-shaped slant surfaces of the each of the pair of lead-in/out portions are connected with the guide groove by smooth curved surfaces.

3. A wire harness comprising:
the tubular outer member according to claim 1 ;
the conductive path housed in and protected by the outer member; and,
the conductive path fixing member which fixes the conductive path to the outer member,
wherein the conductive path fixing member includes the conductive path winding portion and a lock portion,
wherein the conductive path winding portion extends like the line or the belt and winds the conductive path, and
wherein the lock portion maintains a winding state of the conductive path winding portion.

4. The wire harness according to claim 3 ,
wherein the lock portion includes a panel lock portion which is configured to be locked on a through-hole of a panel member of a vehicle.

5. The tubular outer member according to claim 1 ,
wherein the pair of lead-in/out portions are protruded from the outer surface of the outer member.

6. A manufacturing method for a tubular outer member which houses and protects a conductive path, the manufacturing method comprising:
forming a fixing member mounting portion in which a conductive path fixing member is to be mounted so as to fix the conductive path;
forming a guide groove configured to guide a conductive path winding portion extending like a line or a belt in the conductive path fixing member;
forming a pair of lead-in/out portions, wherein the conductive path winding portion is to be inserted to and pulled out from the pair of lead-in/out portions;
forming the guide groove by making a part of an inner surface of the outer member shallowly recessed and extended in a circumferential direction;
forming each of the pair of lead-in/out portions by making the guide groove recessed in a valley-like shape when viewed from inside and making an outer surface of the outer member protruded in a mountain-like shape when viewed from outside; and
cutting away a part of the each of the pair of lead-in/out portions which is located on an inside bottom and an outside top so as to form a lead-in/out opening.

7. The manufacturing method according to claim 6 ,
connecting valley-shaped slant surfaces of the each of the pair of lead-in/out portions with the guide groove by smooth curved surfaces.
