a spring holder being fixed at said loop of the wiring harness and having an elastic arm; and
a flat spring, a front end of which is fixed at the spring holder, energizing the loop for increasing a radius of the loop,
whereby the elastic arm is continuously and elastically in contact with an inner wall of the protector.
2. The continuous power supply device according to claim 1 , wherein the elastic arm has a projection on an outer surface at an front end thereof to be in contact with the inner wall of the protector.
3. The continuous power supply device according to claim 2 , wherein the elastic arm is formed by cutting a side wall of the spring holder partially into an arm shape.
4. The continuous power supply device according to claim 2 , wherein the elastic arms are provided at both sides of the spring holder in a lateral direction and perpendicular to an inner wall of a base of the protector, to be respectively in contact with the inner wall of the base and an inner wall of a cover of the protector.
5. The continuous power supply device according to claim 2 , wherein the elastic arms are provided symmetrically on mirror planes at the both sides of the spring holder.
6. The continuous power supply device according to claim 2 , wherein the elastic arms are provided rotation symmetrically in a vertical direction at the both sides of the spring holder.
7. The continuous power supply device according to claim 3 , wherein the elastic arms are provided at both sides of the spring holder in a lateral direction and perpendicular to an inner wall of a base of the protector, to be respectively in contact with the inner wall of the base and an inner wall of a cover of the protector.
8. The continuous power supply device according to claim 3 , wherein the elastic arms are provided symmetrically on mirror planes at the both sides of the spring holder.
9. The continuous power supply device according to claim 7 , wherein the elastic arms are provided symmetrically on mirror planes at the both sides of the spring holder.
10. The continuous power supply device according to claim 1 , wherein the elastic arm is formed by cutting a side wall of the spring holder partially into an arm shape.
11. The continuous power supply device according to claim 10 , wherein the elastic arms are provided at both sides of the spring holder in a lateral direction and perpendicular to an inner wall of a base of the protector, to be respectively in contact with the inner wall of the base and an inner wall of a cover of the protector.
12. The continuous power supply device according to claim 10 , wherein the elastic arms are provided symmetrically on mirror planes at the both sides of the spring holder.
