In the inner member 22, the support pin portion 54 and the support cylindrical portion of the rotation portion 51 are supported by the bearing portion provided on the upper wall portion 32 and the lower wall portion 33 of the outer member 21. Thereby, the inner member 22 is supported swingably around the vertical axis (rotation axis O) with respect to the outer member 21 in a state where the rotation portion 51 is accommodated in the inner accommodation recess 31. The holding portion 52 is formed in a tubular shape, and extends laterally from the rotating portion 51. A plurality of locking ribs 55 are formed on the inner peripheral surface of the holding portion 52 at intervals in the axial direction of the holding portion 52. The holding portion 52 holds the end portion of the exterior member 12 in a inserted state. The wire bundle W passed through the exterior member 12 passes through the inner member 22 and is drawn from the support cylindrical portion of the rotating portion 51 and is guided to the outer member 21.

  The exterior member 12 is a cylindrical body made of an electrically insulating synthetic resin, is formed in a bellows shape, and can be easily bent. Specifically, the exterior member 12 is formed of a corrugated tube having flexibility in which a hollow cylindrical bellows shape is continuous. On the outer peripheral surface of the exterior member 12, a plurality of valleys 61 formed in the circumferential direction and a plurality of peaks 62 formed in the circumferential direction are alternately provided continuously along the longitudinal direction.

The end of the exterior member 12 held by the holding portion 52 of the inner member 22 may be a cylindrical portion having no flexibility.

  In the exterior member 12 whose end portion is inserted into the holding portion 52, the locking rib 55 extends in the circumferential direction into the outer peripheral valley portion 61 at the end portion. As a result, the exterior member 12 is held at the holding portion 52 with its end portion being locked by the locking rib 55.

  As shown in FIG. 4, the peripheral wall portion 34 constituting the inner accommodation recess 31 of the outer member 21 according to the present embodiment is formed in an arc surface shape centered on the rotation axis O of the inner member 22. Further, in the peripheral wall portion 34, stoppers 37A and 37B are integrally formed at both ends of a circular arc centered on the rotation axis O of the inner member 22 in a cross sectional view. The stoppers 37A and 37B are protruded toward the inner member 22 and formed only on the upper side in the vertical direction of the peripheral wall portion 34.

  The pivoting portion 51 of the inner member 22 has an outer circumferential surface 56 in the form of a circular arc with the pivot axis O as a center.

The rotation of the inner member 72 is restricted.

  In this reference example, as shown in FIG. 5B, when the inner member 72 is rotated, the clearance between the peripheral wall portion 74 of the outer member 71 and the outer peripheral surface 76 of the rotating portion 81 of the inner member 72 is , Increases and decreases at both ends in the circumferential direction. Therefore, for example, when the gap between the peripheral wall 74 and the outer circumferential surface 76 is wide and the inner member 72 is rotated in a state where foreign matter enters when the gap is narrowed, the foreign matter is a gap between the circumferential wall 74 and the outer circumferential surface 76 It may bite in and cause malfunction.

  On the other hand, in the vehicle-body-side power supply tool 14 according to the present embodiment, the peripheral wall 34 of the outer member 21 and the outer peripheral surface 56 of the rotating portion 51 of the inner member 22 both have the rotation axis O of the inner member 22 It is formed in the shape of a circular arc centered on the center. Therefore, when the inner member 22 is rotated with respect to the outer member 21, the gap between the peripheral wall portion 34 of the outer member 21 and the outer peripheral surface 56 of the inner member 22 is constant without changing at both end portions in the circumferential direction. Maintained. As a result, in the vehicle-side power supply tool 14 according to the present embodiment, the operation failure due to the foreign matter caught in the gap between the peripheral wall portion 34 of the outer member 21 and the outer peripheral surface 56 of the inner member 22 is suppressed. It can operate smoothly following the relative movement of exterior member 12 and the vehicle body accompanying the opening and closing of.

  Further, in the vehicle-side power supply tool 14 according to the present embodiment, the rotation of the inner member 22 is set in advance by the engagement piece 57 of the rotating inner member 22 contacting the stoppers 37A and 37B of the outer member 21. Restricted to Therefore, the rotation of the inner member 22 can be reliably restricted without the structure in which the outer peripheral surface 56 of the inner member 22 is brought into direct contact with the peripheral wall portion 34 of the outer member 21 to restrict the rotation.

  Furthermore, the locking piece 57 and the stoppers 37A and 37B according to the present embodiment are provided only at the upper part in the vertical direction in the gap between the peripheral wall portion 34 of the outer member 21 and the outer peripheral surface 56 of the inner member 22. Therefore, a space 38 is formed in the lower portion in the vertical direction in the gap between the peripheral wall portion 34 of the outer member 21 and the outer peripheral surface 56 of the inner member 22 and a locking piece of foreign matter which has entered the gap between the peripheral wall 34 and the outer peripheral surface 56 It is possible to suppress the biting between 57 and the stoppers 37A and 37B, and to smoothly control the rotation and rotation of the inner member 22. The gap between the stoppers 37A and 37B and the outer peripheral surface 56 and the gap between the locking piece 57 and the peripheral wall 34 are sufficiently smaller than the gap between the peripheral wall 34 and the outer peripheral surface 56. Thus, the entry of foreign matter into the gap between the stoppers 37A and 37B and the outer peripheral surface 56 and the entry of foreign matter into the gap between the locking piece 57 and the peripheral wall portion 34 can be suppressed.

  And according to this embodiment, the wire harness 11 provided with the vehicle body side electric power supply tool 14 which follows the relative movement of the exterior member 12 and a vehicle body (structure) and operate | moves smoothly can be provided.
