  In the initial state, the wire harness is in the first protector 3, the cover portion 37 is closed, and the first protector 3 is permanently installed in the vehicle 7. Further, as shown in FIG. 1, the second protector 5 is assumed to be separated from the first protector 3 in a predetermined direction by a predetermined distance and to have a predetermined posture with respect to the first protector 3.

  From the initial state, the first protector 13 is engaged with the first engaged part 9 by linearly moving the second protector 5 in a predetermined direction (the direction of arrow A1 in FIG. 1). Combine.

  Next, with the above engagement state maintained, the second protector 5 is rotated in a predetermined direction (the direction of the arrow A3 in FIG. 1), whereby the second engagement portion 15 is moved to the second engaged state. Engage with the joint 11.

  Accordingly, the second protector 5 is installed (temporarily fixed) on the first protector 3.

  Subsequently, the fixing clip 31 is installed, and a nut is screwed into the stud bolt 33 passing through the through hole 83 of the vehicle locking portion 69 of the second protector 5, so that the bottom plate portion of the vehicle locking portion 69 is secured. By sandwiching 81 between the vehicle 7 and the nut, the main installation (fixation) of the second protector 5 is completed.

  According to the protector fixing structure 1, the second protector 5 moves in the first predetermined manner with respect to the first protector 3, whereby the first engaging portion 13 becomes the first engaged portion 9. After the engagement, the second protector 5 moves in the second predetermined manner relative to the first protector 3, so that the second engaging portion 15 is second engaged. Since the second protector 5 is configured to be engaged with the portion 11 and installed (temporarily fixed) to the first protector 3, the second protector 5 is connected to the first protector 3 or the vehicle 7. For example, it is necessary to perform the operations of the above-described two modes at least in the reverse order to the order described above, and the temporarily retained second protector 5 is removed from the first protector 3 or the vehicle 7. It is hard to come off.

  In addition, in the conventional protector fixing structure 301, two fixing clips 309 are necessary to prevent the temporarily fixed protector 305 from coming off. However, according to the protector fixing structure 1, there are two kinds of modes. Since the second protector 5 is temporarily fixed by the movement, the temporary fixing of the second protector 5 can be made more reliable with only one fixing clip 31.

  Moreover, according to the protector fixing structure 1, the 1st engaging part 13 is provided with the insertion piece 19 which protrudes from the main-body part 17 of the 2nd protector, and the 1st to-be-engaged part 9 is comprised. It comprises a hole 23 formed in the body portion 21 of the first protector, and the first engagement portion 13 is engaged with the first engaged portion by inserting the insertion piece 19 into the hole 23. Since it is configured to be engaged with the portion 9, it is easy to install the second protector 5 on the first protector 3, and the second protector 5 is attached to the first protector 3. (For example, a configuration in which the first engaged portion 9 and the first engaging portion 13 are rotated in a predetermined direction about the engaging portion of the first engaged portion 13; Can be easily obtained.

  Further, according to the protector fixing structure 1, the second protector 5 is connected to the first engaging portion 13 while the first engaging portion 13 is engaged with the first engaged portion 9. The elastic part 25 is elastically deformed by rotating in a predetermined direction around the engaging part with the first engaged part 9, and the elastic part 25 is substantially restored by further rotating. The locking part 27 is locked to the locked part 29, the second engaging part 15 is engaged with the second locked part 11, and the second protector 5 is installed on the first protector 3. In order to remove the second protector 5 from the first protector 3, it is necessary to elastically deform the elastic portion 25 separately from the rotation of the second protector 5. . Thereby, the 2nd protector 5 installed in the 1st protector 3 becomes difficult to remove | deviate from the 1st protector 3 (it does not come off easily).

  Moreover, according to the protector fixing structure 1, the installation state of the second protector 5 on the first protector 3 can be reliably maintained by using the fixing clip 31.

  In the above description, the directions may be changed as appropriate. For example, the front-rear direction and the left-right direction may be interchanged.
