Curvature regulating member and power supply device

1. A curvature regulating member comprising:

a plurality of member pieces arranged along a wire harness and each having a receiving groove for accommodating the wire harness; and

a flexible connection coupling the member pieces adjacent to each other,

wherein the curvature regulating member regulates a curvature of the wire harness on a predetermined plane by contact with the adjacent member pieces, and

wherein a strip projection is provided in an inner surface of the receiving groove in at least one of the plurality of the member pieces, and a recessed portion is provided in an area including the strip projection in the inner surface, and

wherein the strip projection and the recessed portion are provided to a portion of the inner surface of the receiving groove at which the flexible connection is not provided.

2. The curvature regulating member according to claim 1 , wherein the recessed portion is formed with a depth in which the strip projection is received.

3. The curvature regulating member according to claim 2 , wherein each of the plurality of the member pieces has a pair of opposed walls opposed to each other so as to sandwich the wire harness between the opposed walls and a joining wall connecting one side to another side of the pair of the opposed walls,

wherein the recessed portion is formed by a pair of opposed surfaces opposed to each other in the pair of the opposed walls and a continuous surface continuing the opposed surfaces in the joining wall, and

wherein a recessed part formed in the pair of the opposed surfaces in the recessed portion has a tapered shape toward the joining wall in a plane view with respect to each of the pair of the opposed surfaces.

4. A power supply device provided in a vehicle having a vehicle body and a slide member and electrically connecting the vehicle body and the slide member, comprising:

a wire harness arranged between the vehicle body and the slide member; and

the curvature regulating member arranged along the wire harness and described in claim 3 .

5. A power supply device provided in a vehicle having a vehicle body and a slide member and electrically connecting the vehicle body and the slide member, comprising:

a wire harness arranged between the vehicle body and the slide member; and

the curvature regulating member arranged along the wire harness and described in claim 2 .

6. The curvature regulating member according to claim 1 , wherein each of the plurality of the member pieces has a pair of opposed walls opposed to each other so as to sandwich the wire harness between the opposed walls and a joining wall connecting one side to another side of the pair of the opposed walls,

wherein the recessed portion is formed by a pair of opposed surfaces opposed to each other in the pair of the opposed walls and a continuous surface continuing the opposed surfaces in the joining wall, and

wherein a recessed part formed in the pair of the opposed surfaces in the recessed portion has a tapered shape toward the joining wall in a plane view with respect to each of the pair of the opposed surfaces.

7. A power supply device provided in a vehicle having a vehicle body and a slide member and electrically connecting the vehicle body and the slide member, comprising:

a wire harness arranged between the vehicle body and the slide member; and

the curvature regulating member arranged along the wire harness and described in claim 6 .

8. A power supply device provided in a vehicle having a vehicle body and a slide member and electrically connecting the vehicle body and the slide member, comprising:

a wire harness arranged between the vehicle body and the slide member; and

the curvature regulating member arranged along the wire harness and described in claim 1 .
