Description

  The present invention relates to a holding structure for a harness exterior member that holds an end portion of a harness exterior member such as a corrugated tube or a caterpillar member of a wire harness for supplying power to, for example, a slide door of an automobile without leaving the slide door or the like. It is about.

  Conventionally, for example, when a wire harness is routed from a vehicle body (fixed structure) of an automobile to a slide door (slide structure) and power is always supplied, a plurality of electric wires are used as a wire harness, It is known to cover and form an exterior member such as a caterpillar member.

  For example, in Patent Document 1 (not shown), a fixing member having a substantially U-shaped longitudinal section is fixed to a slide door, and a swinging member is provided on the fixing member so as to be rotatable in the horizontal direction at the upper and lower shafts. It is described that one end of the corrugated tube of the wire harness is held by the swing member.

  The corrugated tube is a structure in which circumferential grooves and ridges are alternately arranged in the longitudinal direction of the tube, and ribs project from the inner peripheral surface of the horizontal harness insertion hole of the swinging member, and the ribs have an oval cross section. The concave groove of the corrugated tube is engaged and fixed (see paragraph number 0049 of Patent Document 1).

  Further, in Patent Document 2 (not shown), a wire harness is routed from a harness surplus length absorbing device on the slide door side to a harness fixing member on the vehicle body side, and the wire harness is a caterpillar-shaped exterior member on the vehicle body side. The harness fixing member on the vehicle body side is composed of a base and a cover that can be divided into upper and lower parts, and a rotating body that is rotatably arranged in the circumferential direction between the base and the cover. It is described that one end portion of the outer package member is connected to be swingable.

JP 2007-151377 A (FIGS. 1 and 2) Japanese Patent Laying-Open No. 2005-8010 (FIG. 1) Japanese Patent Laying-Open No. 2004-3618 (FIG. 1)

  However, in the above-described conventional structure, for example, using a different embodiment shown in FIG. 7, it is routed between the swinging member 41 on the slide door side of the automobile and the swinging member 42 on the vehicle body side. When the bent corrugated tube (harness exterior member) 1 made of synthetic resin of the wire harness is stepped on by the person getting on and off when the sliding door is fully opened or half-opened, as shown in FIG. There is a concern that the swinging member 41 may be detached from the horizontal cylindrical harness holding portion 41a.

When the end portion of the corrugated tube 1 is detached from the harness holding portion 41a, it becomes impossible to regulate the smooth bending locus of the wire harness between the sliding door and the vehicle body (crossover portion), and the bending durability of the wire harness Raises concerns that it could decline.

  This is not limited to the external force caused by stepping, and may occur in the same manner even when the corrugated tube 1 interferes with other parts or when a strong external force acts in the radial direction (cross direction) of the corrugated tube 1. In addition, the direction of the external force in the intersecting direction is not limited to the downward direction, and may act in the lateral direction or the upward direction.

  Further, when a caterpillar member made of synthetic resin is used as the harness exterior member instead of the corrugated tube 1, the end portion of the caterpillar member may be deformed by the external force and detached from the swinging member 41. Even when the end of the harness exterior member 1 is held not only by the swinging member 41 but also by a fixed member that cannot swing, the end of the harness exterior member 1 is similarly detached from the fixed member by an external force. It can happen.

It is done.

  It is conceivable to step on the corrugated tube 1 of the wire harness when a person gets on and off when the sliding door of FIG. 7 is fully opened or half-opened. In this case, as described in FIG. Since the reinforcing member 3 protrudes in the longitudinal direction of the corrugated tube from the harness holding wall portion 10 of the swinging member 2 in the device 23 (FIG. 4), the corrugated tube 1 is closer to the front side than the rib 7 on the front side of the swinging member 2. And the concave groove 4 of the corrugated tube 1 is prevented from being detached from the rib 7.

  The reinforcing member 3 can also be applied to a power supply device on the vehicle body side. In this case, the corrugated tube is detached from the swinging member of the power supply device on the vehicle body side in the same manner as the power supply device on the slide door side. Is prevented. The power feeding device on the vehicle body side does not necessarily need to use the swinging member 2. In this case, a harness holding member having a tubular (annular) harness holding wall portion is used instead of the swinging member 2.

  In the above embodiment, the lower bearing portion 12 of the swinging member 2 in FIG. 2 can be replaced with a shaft portion, and the lower shaft portion 30 of the fixing member 22 can be replaced with a bearing portion.
