  The flexible hinge portion 30 is integrally provided on the edge 12 a on the other side wall 13 of the protector body 10 located on the side away from the bottom wall 11 when the protector body 10 is molded. This flexible hinge part 30 becomes a rotation fulcrum of the site | part connected with this flexible hinge part 30 by flexible deformation.

  The lid member 40 extends integrally with the flexible hinge portion 30 and opens and closes the opening portion of the protector main body 10 by a pivoting operation using the flexible hinge portion 30 as a pivot as shown by an arrow R1 in FIG. It is a possible lid.

  As shown in FIG. 8, the clamp engaging portion 41 is mounted on the lid member 40 so that the lid member 40 engages with the protruding portion 21 of the clamp 20 when the open portion of the protector body 10 is closed. It is a hole. The clamp engaging portion 41 holds the lid member 40 in a state where the open portion of the protector body 10 is closed by engaging with the protruding portion 21.

  The harness protector 1 described above accommodates and protects the wire harness 2 routed in the vehicle body in the harness housing space 15.

  Then, in the clamp 20 in the harness protector 1 of the present embodiment, the protruding portion 21 through which the lid member 40 is inserted engages with the clamp locking portion 52 provided in the structural member 51 on the vehicle body side as shown in FIG. The harness protector 1 also serves as a vehicle body connecting portion for fixing the harness protector 1 to the vehicle body.

  The harness protector 1 of the present embodiment is an integrally molded product of resin in which the clamp 20 is insert-molded, and is manufactured by the vacuum forming method shown in FIGS. 4 (a) to 4 (g).

  FIG. 4A to FIG. 4G schematically show the procedure of the manufacturing process by the vacuum forming method. These drawings show a series of procedures from manufacturing a flat plate-shaped resin plate material 1A to manufacturing a useful portion (molded product) 1Ab that has been completed with a U-shaped molding process.

  FIG. 4A shows a sheet (plate material) heating step. In this sheet heating process, a single resin plate 1A that is a raw material of the harness protector 1 is heated by heaters 2A and 2B that are arranged opposite to each other with the resin plate 1A interposed therebetween, so that the resin plate 1A is in a softened state. To.

  During this process, the resin plate material 1A that receives the hot air 2a, 2b from the heaters 2A, 2B is kept in a tensioned state by urging the plate material gripping members 4 gripping both ends in a direction away from each other.

  FIG. 4B shows a sheet moving process. This sheet moving step is a step of transferring the resin plate 1A that has been brought into a predetermined softened state by the sheet heating step of FIG.

  The vacuum molding die 5 is a die having a structure including a raw material molding surface 5a on which the resin plate material 1A is placed and a vacuum suction hole 5b. The raw material molding surface 5a is a mold surface on which the resin plate material 1A is placed. A plurality of vacuum suction holes 5b are provided through the raw material molding surface 5a so as to vacuum-suck the resin plate 1A to the raw material molding surface 5a.

  The vacuum forming die 5 of the present embodiment is equipped with a clamp support portion 5 c that holds the clamp 20 and enables the insert molding of the clamp 20.

  FIG. 4C shows a mold setting process in which the resin plate material 1 </ b> A in a predetermined softened state is pressed against the raw material molding surface 5 a of the vacuum molding mold 5. In this step, the resin plate 1A is set in a state of being in contact with the clamp 20 and the raw material molding surface 5a.

  FIG. 4D shows a molding process. In this molding step, the resin plate material 1A that has been softened by the heating step is vacuum-adsorbed on the raw material molding surface 5a of the vacuum molding die 5, and the resin plate material 1A is cooled and cured in the adsorbed state. The plate material 1A is formed into the shape of the raw material forming surface 5a.

  Through this step, a part of the resin plate material 1A is brought into close contact with the proximal end portion of the clamp 20, and a state in which the clamp 20 is fixed to the resin plate material 1A can be obtained.

  FIG. 4 (e) shows a mold release process in which the resin plate material 1 </ b> A that has been molded is separated from the vacuum mold 5.

  FIG. 4F shows a processing step for performing a trimming process for cutting off the excess portion 1Aa on the resin plate 1A detached from the vacuum mold 5 from the useful portion 1Ab. A boundary portion 1Ac between the extra portion 1Aa and the useful portion 1Ab is a separation position.

  In FIG. 4G, only the useful part 1Ab is left after the forming process by the vacuum forming shown in FIGS. 4A to 4E and the trimming process shown in FIG. Shows the completed state.

  Next, a procedure for routing the wire harness 2 on the vehicle body using the harness protector 1 of the present embodiment will be described. First, as shown in FIGS. 5 and 6, the wire harness 2 is inserted into the harness housing space 15 of the protector body 10. Next, the lid member 40 is rotated in the direction of the arrow R2 in FIG. 6 so that the lid member 40 closes the open portion of the protector body 10 as shown in FIGS. As shown in FIG. 8, when the lid member 40 is closed, the projection member 21 passes through the clamp engaging portion 41 on the lid member 40, so that the lid member 40 closes the open part of the protector body 10. Locked to the state.

  Next, as shown in FIGS. 9 and 10, the harness protector 1 is installed on the structural member 51 of the vehicle body where the harness protector 1 is routed to the clamp engaging portion 41, and the protrusion on the harness protector 1 is installed. 21 is engaged with a clamp engaging portion 52 which is a clamp engaging hole on the structural member 51. The protrusion 21 fixes the harness protector 1 to the structural member 51 by engagement with the clamp locking portion 52.

  In the case of the harness protector 1 of the embodiment described above, the lid member 40 that covers the open part of the protector body 10 so as to be openable and closable is integrally formed with the protector body 10 together with the flexible hinge part 30. The clamp 20 that is integrally provided functions not only as a lid member locking member that holds the lid member 40 in a closed state, but also as a vehicle body fixing component that fixes the harness protector 1 itself to the vehicle body (structural member 51). Function. Therefore, a separate lid member and body fixing parts are not required.

  Therefore, compared with conventional harness protectors that required separate lids and body fixing parts, the number of components can be greatly reduced, and the manufacturing cost can be reduced by reducing the number of components and the number of assembly processes. be able to.

  Further, in the case of the harness protector 1 of the embodiment described above, the insert molding shown in FIG. 4 is used to produce the resin as an integrally molded product. Can be reduced.

  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.
