A wire harness installation structure includes a wire harness, a protector, and a bending motion mechanism that causes the wire harness to make a bending movement. The wire harness has a first portion that is fixed to the protector, a second portion that is distant from both of the first portion and the protector beyond a bending position of the wire harness, and a third portion that is located between the first portion and the second portion. The second portion and the third portion of the wire harness are fixed on a movable member of the bending motion mechanism, and the wire harness is routed so that a second excess length between the second portion and the third portion is shorter than a first excess length between the first portion and the third portion.

A curvature regulating member and a power supply device to which the curvature regulating member is applied are provided. The curvature regulating member has a plurality of member pieces arranged along a wire harness, and a flexible connection. The curvature regulating member regulates a curvature of the wire harness on a predetermined plane by contact with the adjacent member pieces. A burr (strip projection) is provided in an inner surface of the receiving groove of the wire harness in at least one of the member pieces. Further, a recessed portion is provided in an area of the inner surface including the burr (strip projection).

Curvature regulating member and power supply device

A curvature regulating member includes a plurality of member pieces to be arranged along a wire harness and a flexible connecting part connecting adjacent member pieces. The adjacent member pieces are configured to contact each other, thereby regulating curvature of the wire harness on an X-Y plane. Each member piece includes a recessed part recessed toward a direction away from an adjacent member piece on one side, and a second protrusion configured to be inserted in the recessed part provided on an adjacent member piece on another side when adjacent member pieces contact each other. The recessed part includes a slanted face extending away from the adjacent member piece on the one side as leaving from both ends in a widthwise direction. The second protrusion includes a slanted face extending toward the adjacent member piece on the another side as leaving from both ends in the widthwise direction.

A curvature regulation member to be inserted into a corrugated tube is made of synthetic resin, and integrally includes a belt, and a plurality of bridges standing from both ends in a width direction of the belt. The curvature regulation member is allowed to be curved in a direction that the belt is inside and the bridges are outside. In an opposite direction, curving of the curvature regulation member is restricted by the adjacent bridges abutting on each other. The bridge includes a rectangular plate. Two corners of the plate at a side away from the belt are rounded.

A curvature-restraining member and a power feeding device include a wire harness having an electric wire and a corrugated tube (flexible tube). The curvature-restraining member restrains the wire harness from curving in a predetermined curving direction Dwith a radius of curvature smaller than a reference radius. The curvature restraining member includes a body portion placed near at least one of ends of the corrugated tube and extending in a length direction of the electric wire, and a curved portion extending from one end of the corrugated tube opposite from the former end, and curving in the curving direction Dwith a radius of curvature not less than the reference radius with such a length that it falls within the straightly extending corrugated tube.
