Wire harness wiring unit and wire harness wiring assembly having the same

There is provided a wire harness wiring unit (5) provided to a base plate (10) and a wire harness wiring assembly having the same which can regulate a direction of a curve of a wire harness. The wire harness wiring unit (5) includes the wire harness having a distal and a proximal end portions (22), a first mounting member mounting one end of the proximal end portion (23) to the base plate such that the distal end portion can move in a direction of adjusting a length of the distal end portion, a rod-like harness support parallely-fixed to the proximal end portion from the other end to a middle portion of the proximal end portion, and a second mounting member mounting, to the base plate, a portion of the harness support adjacent to the other end of the proximal end portion such that the harness support can move along the base plate.
