The present invention relates to a fixing structure for a mounted member and a locking component.

Conventionally, as a protector for inserting and protecting electric wires routed in vehicles, etc., and regulating the route, for example, in Patent Document 1, a plate material is bent to form a rectangular cylindrical body, and a rectangular cylindrical body is formed by bending a plate material. A structure has been proposed in which a locking part for attachment to the vehicle body is attached to a through hole provided on one side of the vehicle body.

The above-mentioned through hole is formed in a T-shape in plan view by a rectangular wide part that is wide along the width direction of the plate material and a narrow part that is narrower than the wide part and extends in the longitudinal direction L, and is not engaged. The fastening component includes a clip portion that is attached to the vehicle body, and a locking portion that is inserted into the through hole and held and locked.

The locking part includes a pair of fixing pieces that are narrower than the wide part and wider than the narrow part, and is attached to the square cylindrical body by inserting it from the wide part of the through hole and inserting it into the narrow part. . In this way, the rectangular cylindrical body with the locking part attached to the through hole can be mounted at a predetermined location on the vehicle.

However, when mounted on a vehicle, due to vibrations during driving, etc., the locking part inserted and attached to the narrow part of the through hole moves relatively to the wide part, causing the locking part to move away from the square cylindrical body. There was a risk that it would come off and the attachment to the vehicle body would become unstable.
