In a power feeding device which absorbs a surplus length by enlarging or reducing spirally the diameter of a flat wire harness, a wire harness surplus length absorbing performance is improved, a structure is simplified and a cost is decreased. A power feeding device 1, 31 is used in which a flat wire harness 8 is wound a plurality of times and arranged about a boss part 3 as a center, a spring member 7, 22 is arranged from the boss part to an inside diameter part 9a of a winding part 8 of the flat wire harness, the winding part is urged outward by the spring member and the flat wire harness is arranged at narrow pitches in the diametrical direction in the winding part. The spring member 7, 22 is formed with a plurality of bent flat springs arranged in the radial directions or spiral springs bent in the forms of loops. The boss part 3, the winding part 9 and the spring member 7, 22 are accommodated in an annular wall 2 of a housing 6. At both sides of an opening part 14 of the annular wall 2 for introducing out the wire harness, curved surfaces 15 are formed for guiding the wire harness.
