Exterior member and wire harness
An exterior member which is tubular and which accommodates and protects one or multiple conductive paths, the exterior member is provided with a non-slit shape and multiple projections which project on a tube inner surface of the exterior member. The multiple projections respectively have substantially arc-like shapes extending in a tube inner peripheral direction, and the multiple projections are arranged zigzag alternately along a tube axial direction.
1. An exterior member which is tubular and which accommodates and protects one or multiple conductive paths, the exterior member comprising:
a non-slit shape; and
multiple projections which project on a tube inner surface of the exterior member,
wherein the multiple projections respectively have substantially arc-like shapes extending in a tube inner peripheral direction, and the multiple projections are arranged zigzag alternately along a tube axial direction such that a portion of the tube inner surface that opposes a respective one of the multiple projections lacks the multiple projections.
2. The exterior member according to claim 1 ,
wherein each of the multiple projections includes a round portion extending in a substantially arc-like shape in the tube inner peripheral direction, and two oblique portions which respectively continue from the round portion to the tube inner surface and are substantially oblique-shaped, and
wherein each of the multiple projections includes a section along the tube axial direction which is a substantially U-shaped or V-shaped smooth surface.
3. The exterior member according to claim 2 ,
wherein each of the multiple projections includes a shape extending in a length equal to or shorter than a half periphery of the tube inner surface.
4. The exterior member according to claim 2 ,
wherein each of the multiple projections includes a shape extending in a length exceeding a half periphery of the tube inner surface.
5. The exterior member according to claim 4 , wherein the length of each of the multiple projections is not equal to or not longer than a whole periphery of the tube inner surface.
6. The exterior member according to claim 1 , further comprising:
ribs extending along the tube axial direction,
wherein each of the ribs is arranged on each of recesses which are formed on a tube outer surface of the exterior member by the multiple projections.
7. The exterior member according to claim 1 further comprising:
a straight tube part having a straight tube-like shape,
wherein the multiple projections are arranged on the straight tube part.
8. A wire harness comprising:
the exterior member which is tubular and which accommodates and protects one or multiple conductive paths; and,
one or multiple conductive paths which are accommodated into and protected by the exterior member,
wherein the exterior member comprising:
a non-slit shape; and
multiple projections which project on a tube inner surface of the exterior member,
wherein the multiple projections respectively have substantially arc-like shapes extending in a tube inner peripheral direction, and the multiple projections are arranged zigzag alternately along a tube axial direction.
