A corrugated tube which can easily bend a wiring harness in one direction and can make the wiring harness hardly bend in another direction crossing the one direction at right angles. The wiring harness is made so that it can hardly bend in the other direction, so that the slack of the wiring harness for use in supplying electric power to a slide door can be effectively prevented from occurring. The corrugated tube includes: dented grooves and projecting strips formed on an outer periphery of the corrugated tube and arranged alternately in a longitudinal direction of the corrugated tube; and a reinforcing rib formed projecting from an outer peripheral surface of the dented groove and extending beyond an outer peripheral surface of the projecting strip, the reinforcing rib being formed in the longitudinal direction of the corrugated tube.

A power supply apparatus for a sliding structure, which can be arranged in a small space in the sliding structure, the power supply apparatus including a wiring harness having a vertical path portion; a harness fixing member for fixing one end of the vertical path portion of the wiring harness on the sliding structure; a fixed base fixed on the sliding structure for holding the other end of the vertical path portion; and a swing member mounted on the fixed base to swing freely in a horizontal plane for allowing the vertical path portion to be twisted along a circumferential direction of itself and leading a part of the wiring harness continued to the vertical path portion toward a fixed structure. Instead of the fixed base, a movable base', and a guide rail to be engaged with the movable base can be applied.

Power supply apparatus for sliding structure

Providing a power supply apparatus for a sliding structure, which can prevent a wiring harness from penetrating into an opening when the sliding structure is opened half, and sound noise when the sliding structure is closed, the power supply apparatus for the sliding structure includes a car body, a sliding door mounted slidably on the car body, the wiring harness wired between the car body and the sliding door, a fixed portion and a limiting member. One end of the wiring harness is fixed at the car body. The other end of the wiring harness is fixed at the fixed portion, which is mounted on the sliding door. The limiting member abuts on a bottom edge of an inner edge of an opening.

A wiring harness is horizontally swingably arranged from the sliding door to a vehicle body. A resilient member arranged at the sliding door energizes the wiring harness toward the vehicle body when the sliding door is fully closed, and energizes to bend the wiring harness when the sliding door is started to be opened. The wiring harness at the sliding door is supported by an oscillation member, and the resilient member energizes the wiring harness toward the vehicle body via the oscillation member. The oscillation member is mounted on a slider, the slider is engaged with a horizontal guiding rail, and the wiring harness is arranged from the slider to the oscillation member. The wiring harness is fixed to a fastening device at the vehicle body side, and the fastening device is arranged obliquely and outwardly against a direction of closing the sliding door. When the sliding door is fully closed, the wiring harness is horizontally supported along an oblong harness guiding member at the sliding door side.

A method includes a first, a second and a third step, and a circuit member is installed in a resin-molded panel simultaneously when this resin-molded panel is vacuum formed. In the first step, the circuit member to be installed is placed on an upper surface of a circuit member-installing portion formed on and projecting from a front surface of a base mold. In the second step, a heated and softened panel material is laid on the front surface of the base mold. In the third step, the air between the panel material and the base mold is drawn via notch spaces and air-drawing holes.
