For miniaturizing a power supply structure to absorb slack of a wire harness and improving bending durability, a continuous electric power supply device 1 includes a wire harness 3 formed to have a loop portion 4 , an elastic member 6 along the loop portion 4 , the elastic member energizing the loop portion to expand in a radial direction. The loop portion 4 and the elastic member 6 are disposed in a protector 2 . The protector has a opening 13 for leading the harness and a guide portion 7 for supporting the loop portion 4 at a position opposite to the opening 13 . The elastic member, flat spring 6 can have a length forming a loop shape to intersect itself.
