Abstract

An electric wire holding member ( 20 ) includes: a main body portion ( 21 ) formed in a cylindrical shape having a central axis line (X 1 ); a plurality of electric wire accommodating portions ( 22 a, 22 b , and 22 c ) provided to penetrate through the main body portion ( 21 ) along the central axis line (X 1 ), respectively, and are formed to be capable of individually accommodating electric wires ( 3 a, 3 b , and 3 c ), respectively, the electric wire accommodating portions ( 22 a, 22 b , and 22 c ) being disposed along a circumferential direction around the central axis line (X 1 ) at equal intervals in a cross section as viewed from an axial direction; and a space portion ( 23 ) formed between two electric wire accommodating portions adjacent to each other along the circumferential direction to penetrate through the main body portion ( 21 ) along the central axis line (X 1 ).

First claim

1 . An electric wire holding member comprising:
a main body portion that is formed in a cylindrical shape having a central axis line as an axial center; a plurality of electric wire accommodating portions that are provided to penetrate through the main body portion along the central axis line, respectively, and are formed to be capable of individually accommodating electric wires, respectively, the plurality of electric wire accommodating portions being disposed along a circumferential direction around the central axis line at equal intervals in a cross section as viewed from an axial direction along the central axis line; and a space portion that is formed between two electric wire accommodating portions adjacent to each other along the circumferential direction out of the plurality of electric wire accommodating portions to penetrate through the main body portion along the central axis line.

2 . The electric wire holding member according to claim 1 , wherein
the electric wire accommodating portions are formed such that outlines of the electric wires to be accommodated in the electric wire accommodating portions at least come in contact with the cylindrical outline of the main body portion from an inner peripheral side in the cross section.

3 . The electric wire holding member according to claim 1 , wherein
the electric wire accommodating portions are formed such that the electric wires are capable of being fitted thereinto from an outer peripheral side of the main body portion.

4 . The electric wire holding member according to claim 1 , wherein
the space portion is integrally formed including an area from between two electric wire accommodating portions adjacent to each other along the circumferential direction out of the plurality of electric wire accommodating portions to the central axis line in the cross section.

5 . The electric wire holding member according to claim 1 , further comprising:
outer edge portions that are erected from a cylindrical outer peripheral surface of the main body portion and are formed to extend along the circumferential direction.

6 . A wire harness comprising:
an electric wire portion in which three or more electric wires are gathered in the same direction; an electric wire holding member according to claim 1 which maintains an arrangement of each electric wire of the electric wire portion around the central axis line; a shield member that collectively encloses an outer peripheral side of the electric wire holding member which holds the electric wire portion; and a protective member that covers the outer peripheral side of the electric wire holding member enclosed by the shield member.

7 . The wire harness according to claim 6 , wherein
the electric wire holding member is formed so as to enclose a part of the electric wire portion in a longitudinal direction, and a plurality of electric wire holding members are provided along a longitudinal direction of the electric wire portion at predetermined intervals.

8 . The wire harness according to claim 6 , wherein
the electric wire holding member is formed so as to enclose an overall area of the electric wire portion in the longitudinal direction of the electric wire portion.
