  • the second cable 12 which is spirally wound in the second housing space S2, deforms so as to reduce its diameter in a plan view, as shown in FIG. 9( b), allowing the second cable 12 to be smoothly pulled out from the second housing space S2 toward the lead-out portion 42. Therefore, the cable 10 is pulled out from the lead-out portion 42 downward ZD.
  • the second cable 12 inclines toward the downward side ZD as it moves toward the left side XL, and is wound around the outer surface of a cylindrical portion 452 that is assembled so as to be rotatable around a rotation axis along the connecting shaft portion 451. Therefore, when the base-end cable 14 is pulled out from the lead-out portion 42, the cylindrical portion 452 rotates, smoothly pulling out the second cable 12 from the inside to the outside of the housing main body 41, and the pulling direction of the second cable 12 can be easily changed from the left side XL to the downward side ZD. Furthermore, pulling out the second cable 12 rotates the cylindrical portion 452 around which the main surface of the second cable 12 is wound, so sliding between the cylindrical portion 452 and the second cable 12 prevents the second cable 12 from rubbing against each other and becoming worn.
  • the base-end cable 14 is pulled back from the lead-out portion 42, causing the cylindrical portion 452 to rotate.
  • This allows the second cable 12 to be smoothly pulled in from the outside toward the inside of the housing main body 41, and the direction in which the second cable 12 is pulled in can be easily changed from the upper side ZU to the right side XR.
  • pulling back the second cable 12 causes the cylindrical portion 452, around which the main surface of the second cable 12 is wrapped, to rotate, preventing the cylindrical portion 452 and the second cable 12 from sliding against each other, which can prevent the second cable 12 from rubbing and wearing out.
  • the cable winding device 1 is pulled out or wound from the second storage section 40 in response to movement of the handle 820 in the axial direction Z, so the length of the base-end cable 14 can be adjusted in response to movement of the handle 820 in the axial direction Z.

  • the spiral spring 60a is made of a spiral spring material wound in the same direction as the spiral direction of the second cable 12 (second outer winding portion 122). This allows for a simple structure, and the spiral spring 60a can be efficiently biased by pulling out the second cable 12 (second outer winding portion 122), and the biasing force can be efficiently applied to the second cable 12 (second outer winding portion 122) being wound.
  • the second cable 12 has a second internally wound portion 121 wound around the inner diameter side of the second storage space S2, a second externally wound portion 122 around which the cable 10 is wound around the outer diameter side, and an arc-shaped second wound portion 123 that is the boundary between the second internally wound portion 121 and the second externally wound portion 122.
  • the second storage space S2 is also provided with a rotary table 51 that is rotatable around the rotator 31, a rotating roller 52 that is supported by the rotary table 51 and is arranged on the inner surface of the second wound portion 123 and is rotatable around a direction parallel to the axial direction Z, and a guide surface 53 that is located circumferentially away from the outer surface of the rotating roller 52 on the rotary table 51 and is arranged on the outer surface of the second wound portion 123.
  • One end of the spiral spring 60a is fixed to the second storage space 40a, 40d, and the other end is fixed to the rotary table 51.
  • a rotary table 51 that is rotatable around a rotation axis (rotation center axis R), and a rotating roller 52 that is supported by the rotary table 51 and is rotatable around the rotation axis.
  • the rotating roller 52 is disposed on the inner circumferential surface of the second rewinding portion 123. Therefore, when the second rewinding portion 123 moves to one side in the circumferential direction during winding or unwinding of the second cable 12, the inner circumferential surface of the second rewinding portion 123 comes into contact with the rotating roller 52, pulling the rotating roller 52. As a result, the rotary table 51 rotates (revolves) and the rotating roller 52 also rotates (rotates) in response to the unwinding of the second cable 12. This allows the second cable 12 to be smoothly guided. It also prevents the second cable 12 from rubbing against and wearing out.
  • one end of the spiral spring 60a is fixed to the second storage section 40a, 40d, 40e, and the other end is fixed to the rotary table 51. Therefore, when the object to which the cable winding device 1 is attached moves to the other side in the sliding direction (sliding motion), the second rewound portion 123 of the second cable 12 is urged in the winding direction via the rotating roller 52, allowing the second cable 12 to be smoothly wound.
  • the second storage section 40d is arranged on the outer diameter side of the first storage section 30d, and is provided with an insertion slit 37 that holds the boundary between the first cable 11 and the second cable 12.
  • This allows the size in the axial direction Z to be made more compact than when the first storage section 30d and the second storage section 40d are arranged along the axial direction Z. This allows for space savings.
  • the insertion slit 37 holds the boundary between the first cable 11 and the second cable 12, the first cable 11 stored in the first storage space S1 and the second cable 12 stored in the second storage space S2 can be stored without their storage states affecting each other.
  • the first storage section 30, 30c and the second storage section 40, 40a, 40b, 40c are arranged along the axial direction Z. This allows for a more compact size when viewed from the axial direction Z compared to when one of the first storage section 30, 30c and the second storage section 40, 40a, 40b, 40c is arranged on the inner diameter side and the other is arranged on the outer diameter side. This allows for space savings.
  • the handle power supply device 2 uses cable winding devices 1, 1a, 1c, 1d, and 1e, with one side of the first cable 11 connected to an electrical component on the handle 820 that allows for sliding and rotating movements, and the end of the second cable 12 guided from the outlet portions 42, 42b, and 42c connected to an electrical component on the electricity supply source side, and a rotator 31 connected to the handle 820. This allows for electricity to be supplied while responding to the sliding and rotating movements of the handle 820, and allows for a compact configuration.
  • the seat power supply device 3 also uses a cable winding device 1b, with one side of the first cable 11 connected to an electrical component of the seat member 900 that allows sliding and rotational movements, and the end of the second cable 12 that is guided from the outlet portion 42b connected to an electrical component on the electricity supply side, with a rotator 31 connected to the seat member 900.
