A sheath member has a cylindrical and flexible main body to accommodate an electric wire and a deformation restricting portion molded on an outer peripheral side of the main body and extending over a predetermined shape maintaining range such that the main body is maintained in a desired routing shape.
1. A sheath member comprising:
a cylindrical and flexible main body being configured to accommodate an electric wire, the main body including a corrugated tube that has an outer peripheral side with a plurality of alternating convex sections and concave sections; and
a deformation restricting portion engaging at least one of the convex sections and at least one of the concave sections on the outer peripheral side of the corrugated tube, and the deformation restricting portion extending over a predetermined shape maintaining range along a longitudinal direction of the main body such that the main body is maintained in a desired routing shape,
wherein the main body comprises a first body portion and a second body portion that are formed as separate pieces, and
wherein the deformation restricting portion extends to bridge the first body portion and the second body portion.
2. The sheath member according to claim 1 , wherein the shape maintaining range includes a bent section of the main body.
3. The sheath member according to claim 1 , wherein the thickness of the deformation restricting portion in a first direction in a cross section of the deformation restricting portion is greater than the thickness in a second direction perpendicular to the first direction.
4. The sheath member according to claim 1 , wherein the deformation restricting portion includes an inner surface that conforms to the concave sections and the convex sections that are located in the predetermined shape maintaining range.
5. The sheath member according to claim 1 , wherein the deformation restricting portion includes a bridging portion that is spaced away from the main body and parallels the main body in the longitudinal direction.
6. The sheath member according to claim 1 , wherein the main body includes a bent portion and the deformation restricting portion extends along the bent portion.
7. A wire harness comprising:
at least one electric wire; and
the sheath member according to claim 1 , wherein the main body accommodates a portion of the at least one electric wire.
8. A sheath member comprising:
a cylindrical and flexible main body to accommodate an electric wire; and
a deformation restricting portion molded on an outer peripheral side of the main body and extending over a predetermined shape maintaining range along a longitudinal direction of the main body such that the main body is maintained in a desired routing shape,
wherein the main body comprises a first body portion and a second body portion that are formed as separate pieces,
wherein the deformation restricting portion extends to bridge the first body portion and the second body portion, and
wherein the deformation restricting portion has an outer shape corresponding to a shape of a contacting object that is brought into contact with the sheath member when the electric wire is routed.
