  In this way, the protector 11 is fixed to the frame 71, and thus the wire harness W held by the protector 11 is securely held by the frame 71.

  As described above, according to the protector according to the present embodiment, the wire harness W is held in the housing portion S, and the clamp 53 of the support mechanism 51 of the protector lid 13 is moved to the locking hole 72 of the frame 71 of the vehicle or the like. By inserting, the wire harness W can be easily held on the frame 71. Further, since the bracket 52 has strength, the bracket 52 itself is difficult to bend, and the lid main body 23 on which the bracket 52 is formed is also difficult to bend because the bracket 52 plays a role of reinforcing the strength. As a result, since the deformation of the lid main body 23 is suppressed, it is possible to prevent the lid side locking portion 33 of the protector lid 13 from being inadvertently detached from the main body side locking portion 32 of the protector main body 12.

  By the way, if an external force acts on the lid body 23 and the lid body 23 bends even slightly, the vicinity of the lid side locking portion 33 in the lid body 23 is less deformed, but the other lid side locking portion. Deforms greatly as it moves away from 33. In the present invention, the bracket 52 is positioned in the vicinity of the lid-side locking portion 33 by positioning a part of the bracket 52 on the line segment connecting the lid-side locking portions 33 that are respectively positioned at opposite ends of the lid main body 23. Therefore, deformation of the lid body can be suppressed as much as possible.

  Furthermore, in the present invention, the end portion of the bracket 52 that plays the most role in reinforcing the strength of the lid main body 23 is positioned on a line segment that connects the locking portions located at the opposite end portions of the lid main body 23, respectively. The deformation of the lid body can be further suppressed as much as possible. When the clamp 53 is located near the center in the longitudinal direction of the bracket 52, an external force is equally applied to both end portions of the bracket 52, and the external force that is applied to each lid side locking portion 33 is made uniform. As a result, it is possible to prevent an excessive external force from acting on one lid side locking portion 33 and releasing the locking with the main body side locking portion 32 by the lid side locking portion 33.

  In addition, since a part of the bracket 52 is positioned approximately in the middle of the lid-side locking portions 33 formed at the ends of the lid body 23 facing each other, an external force acting on each lid-side locking portion 33 is applied. It is made uniform. As a result, it is possible to prevent an excessive external force from acting on one lid side locking portion 33 and releasing the locking with the main body side locking portion 32 by the lid side locking portion 33.

  In addition, since the bracket 52 has a flat plate shape, the protector lid 13 can be easily molded, and the bracket 52 can effectively function as a reinforcing material that suppresses deformation of the lid main body 23. .

  Further, when the end of the frame 71 on which the protector 11 is disposed has a substantially right-angled edge, the protector 11 is disposed on the frame 71 so that the edge is fitted into a corner formed by the lid body 23 and the bracket 52. The protector 11 can be more closely attached to the frame 71 and securely fixed, and vibration of the protector 11 can be suppressed.

  Further, since the plate of the frame 71 positioned between the locking blade 62 of the clamp 53 and the convex portion 63 of the bracket 52 can be firmly sandwiched, the protector 11 can be more firmly fixed to the frame 71. it can.

  Further, since the extending directions of the protruding portions 63 of the protruding shapes of the two brackets 52 are different, vibrations acting in different directions with respect to the brackets 52 are reliably suppressed by the respective protruding portions 63. As a result, vibration of the protector 11 can be further suppressed.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
