Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for maintaining the shape of a mounted member, which includes a mounted member such as a protector that covers and protects a wire harness or an electric wire, and a mounting member that is mounted on the mounted member, and to a mounting member.

In a vehicle such as an automobile, as a protector that covers and protects electric wires and wire harnesses or regulates their paths, for example, as in Patent Document 1, a plate material is bent to form a rectangular cylindrical body extending in a predetermined direction, and the inside of the body is Some have wires and wire harnesses inserted into the space.

More specifically, the protector of Patent Document 1 is made of a resin plate material, and is formed into a rectangular tubular shape by bending the plate material along creases so that the plate material overlaps doubly on all surfaces. Further, the protector of Patent Document 1 forms a rectangular tubular body having a substantially annular cross section by connecting portions where bent plate members are overlapped with each other by locking parts.

By the way, in the protector of Patent Document 1, plate members are overlapped so that each surface of the quadrangular prism is doubled, and the plate members are connected to each other by locking parts, so the protector tends to be heavy. In such a protector, which tends to be heavy, an unintended load may be applied to the wire harness or the like.

Therefore, it is conceivable to reduce the weight of the protector by, for example, bending a plate material into a substantially U-shape to form a protector having an open cross section with one opening in the orthogonal direction. , there is a problem that the desired cross-sectional shape of the protector cannot be maintained.

The mounting member includes a main body portion having a plurality of abutment surfaces with which the mounted member abuts from an orthogonal direction orthogonal to the predetermined direction, and a main body portion having a plurality of abutment surfaces on which the mounted member abuts against the abutment surface, and the mounted member abuts on the abutment surface. The shape maintaining structure of the mounted member is provided with a regulating portion for regulating separation from the contact surface in a direction.

The open-section-shaped mounting member includes, for example, a mounting member having a substantially U-shaped cross section extending in a predetermined direction, a mounting member having a substantially L-shaped cross section, and the like.
The term "abutting the member to be worn from the orthogonal direction" means that the member to be worn abuts from the inside in the orthogonal direction, or that the member to be worn abuts from the outside in the orthogonal direction.

When the member to be worn contacts the contact surface and separates from the contact surface in the orthogonal direction, for example, the member to be worn is separated so as to tilt in the orthogonal direction, or the member to be worn is tilted in the orthogonal direction. It means to move apart so that it moves.

Thereby, the shape maintaining structure of the mounted member can stably maintain the state in which the mounted member is in contact with the contact surface of the mounted member. Therefore, the shape maintaining structure of the attached member can reliably maintain the desired cross-sectional shape of the attached member.

Further, as an aspect of the present invention, the restricting portion may be configured to fit into a fitted portion provided on the mounted member.
To fit into the fitted portion means that the restricting portion fits into the fitted portion without a gap or loosely fits into the fitted portion.

Further, the pair of holding portions 27 also function as restricting portions that restrict the protector 1 in contact with the side contact surfaces 212a from moving inward in the width direction Y and separating from the side contact surfaces 212a. do.
As shown in FIGS. 9 and 10 , the holding portion 27 of the mounting member 2 is provided at the upper end of the side portion 212 of the main body portion 21 and formed into a shape to be engaged with the protector side portion 12 .

Specifically, as shown in FIG. 11B, the holding portion 27 includes a fitting portion 27a extending inward in the width direction Y from the upper end of the side surface portion 212, and a fitting portion 27a. is integrally formed with a tip portion 27b extending downward from the tip of the .

The fitting portion 27 a is formed so as to fit into the notch portion 15 of the protector side portion 12 . More specifically, as shown in FIG. 11(b), the fitting portion 27a has a substantially flat plate shape with a thickness substantially equal to that of the notch portion 15 in the vertical direction. They are extended with substantially the same length in the width direction Y.

On the other hand, as shown in FIG. 11(b), the tip portion 27b has upper and lower portions facing the side portion 212 with the protector side portion 12 therebetween so that the protector side portion 12 is sandwiched between the side portion 212 of the main body portion 21 and the side portion 212.

As a result, the shape maintaining structure of the wearing member can exhibit the same effects as those of the first embodiment described above. Furthermore, since the holding portion 27, which is the restricting portion, is configured to fit into the notch portion 15 provided in the protector 1, the shape maintaining structure of the mounted member is such that the protector 1 is pushed sideways in the width direction Y. In addition to restricting separation from the contact surface 212a, movement of the protector 1 at least in the longitudinal direction X can be suppressed.

In contrast to the first embodiment described above, the protector 1 in contact with the bottom contact surface 211a contacts the side contact surface 212a and the restricting portion that prevents the protector 1 from moving upward and away from the bottom contact surface 211a. 12 and 13, a fourth embodiment having a different restricting portion that restricts the protector 1 from moving inwardly in the width direction Y away from the side contact surface 212a will be described.
