  In addition, it is not essential that the grommet body 60 includes the harness protection cylinder portion 66.

  The assembly procedure of the door grommet 30 and the wire harness 20 with grommet will be described.

  First, the divided parts 152A and 152B of the second protector part 50 are opened around the hinge part 53 (see FIGS. 12 and 13). And the wire harness 22 is arrange | positioned in half-cylinder part 154A, 154B through the opening on the opposite side to the hinge part 53 among division | segmentation plate-like part 153A, 153B and half cylinder part 154A, 154B. Thereafter, the divided portions 152A and 152B are closed, and the first overlapping portions 153A1 and 153B1 are overlapped with each other, and the second overlapping portions 153A2 and 153B2 are overlapped with each other (FIGS. 14, 15, 16, and 17). reference). Further, the united state of the divided parts 152A and 152B is maintained by locking the lock part 160A to the lock receiving part 160B. As a result, the wire harness 22 is disposed in the cylindrical portion 52b of the second protector portion 50.

  Thereafter, as shown in FIG. 18, the pair of slide protrusions 44 of the first protector portion 40 is positioned on the pressing portion 56 side with respect to the pair of regulating surfaces 58 f from one end side of the second protector portion 50. Then, it is slid between the pair of regulating surfaces 58f and the pair of pressing portions 56 (see FIGS. 20 and 21). At this time, in the direction in which the first protector portion 40 and the second protector portion 50 are separated from each other, the pair of slide protrusions 44 and the pair of restricting surfaces 58f are in sliding contact. Further, in the direction in which the first protector portion 40 and the second protector portion 50 approach each other, the front end side edge portion of the side wall portion 54a of the second protector portion 50 and the plate-like portion 42a of the first protector portion 40 are in sliding contact. Therefore, the first protector portion 40 and the second protector portion 50 are slid and moved in a state where the first protector portion 40 and the second protector portion 50 are regulated at fixed positions in the approaching / separating directions (attachment direction of the attachment portion 48). The unit 40 and the second protector unit 50 are combined. Note that the outward surfaces of the pair of side wall portions 54 a of the second protector portion 50 are in sliding contact with the inward surfaces of the pair of side wall portions 42 b 1 of the first protector portion 40. Therefore, the first protector 40 and the second protector 50 are slid and combined with each other in a state where the first protector 40 and the second protector 50 are relatively regulated in the respective width directions. A guide surface is formed at a position where the thickness of the slide projection 44 is separated from the regulation surface 58f, and the slide projection 44 is sandwiched between the regulation surface 58f and the guide surface, whereby the first protector portion is formed. 40 and the 2nd protector part 50 may be controlled by the fixed position in each approach / separation direction (attachment direction of the attaching part 48).

  But the 1st protector part 40 and the 2nd protector part 50 should just be regulated by the fixed position so that it may not move in the separation | separation direction, and the regulation to a near direction is not essential.

  As described above, when the pair of slide protrusions 44 are slid, the outwardly inclined surfaces of the lock protrusions 45 are in sliding contact with the inward surfaces of the restriction protrusions 58a. The peripheral portion is elastically deformed, and the lock projection 45 and the regulation projection 58a can be displaced away from each other. Then, when the lock protrusion 45 gets over the restriction protrusion 58a and fits into the lock receiving part 58p, the lock protrusion 45 and the restriction protrusion 58a move back in the proximity direction, and the lock protrusion 45 becomes the lock reception part 58p. The retaining protrusion 58a on one side in the extending direction is retained and locked (see FIG. 19). Thereby, the united state of the 1st protector part 40 and the 2nd protector part 50 is maintained.

  Then, the wire harness 22 is inserted into the grommet body 60, and the seal portion 64 a and the auxiliary seal portion 64 b of the grommet body 60 are attached to the pressing portion 56 and the auxiliary pressing portion 57. Note that the mounting of the protector mounting portion 62 of the grommet body 60 may be performed in a state before the first protector portion 40 and the second protector portion 50 are combined.

  According to the door grommet 30 and the grommet-equipped wire harness 20 configured as described above, the wire is inserted into the wire harness lead hole 52bh through the opening around the outer periphery of the wire harness lead hole 52bh with the divided portions 152A and 152B open. By arranging the harness 22 and then closing the plurality of divided portions 152A and 152B, the wire harness 22 can be arranged in the wire harness lead hole 52bh. For this reason, the wire harness 22 can be easily arrange | positioned in the wire harness extraction hole 52bh of the 2nd protector part 50 which is a component of the grommet 30 for doors.

  Moreover, since the operation | work which lets an electric wire with a terminal pass to a wire harness extraction hole can be made different from the past, adhesion of the damage | wound etc. of a terminal can be suppressed and the quality improvement of the wire harness 20 with a grommet can be aimed at.

  Further, since the end portions of the half cylinder portions 154A and 154B that divide the cylinder portion 52b are connected to each other via the hinge portion 53, the hinge portion 53 is connected in the axial direction to connect the divided portions 152A and 152B so as to be opened and closed. Along the axial direction of the tube portion 52b, the tube portion 52b can extend with a certain length. For this reason, it is possible to accurately align and close them while suppressing torsion and the like of the divided portions 152A and 152B.

  In addition, since the first overlapping portions 153A1 and 153B1 are formed at the abutting portions of the divided plate-like portions 153A and 153B of the plate-like portion 52a and overlap each other in the thickness direction, the thickness direction of the divided plate-like portions 153A and 153B The deviation is effectively suppressed.

  Further, second overlapping portions 153A2 and 153B2 are formed at the abutting portions of the divided plate-like portions 153A and 153B of the plate-like portion 52a, and they are in a reverse positional relationship with respect to the first overlapping portions 153A1 and 153B1. Since they overlap in the thickness direction, the shift in both directions in the thickness direction of the divided plate-like portions 153A and 153B is effectively suppressed. Note that the second overlapping portions 153A2 and 153B2 may be omitted. The first overlapping portions 153A1 and 153B1 may also be omitted.

  In addition to the first overlapping portions 153A1 and 153B1 and the second overlapping portions 153A2 and 153B2, other overlapping portions may be provided.

  In addition, since the first overlapping portion 153A1 and the second overlapping portion 153A2 as positioning convex portions are fitted into the recesses 153Ba and 153Bb as positioning concave portions, the divided plate-like portions 153A and 153B extend the abutting portions. It is possible to suppress positional displacement along the current direction.

  It is not essential that the first overlapping portions 153A1 and 153B1 and the second overlapping portions 153A2 and 153B2 have a configuration as a positioning convex portion and a positioning concave portion.

  In this case, the positioning convex part and the positioning concave part may be omitted, or the positioning convex part and the positioning part that are fitted to each other in a different place from the first overlapping part 153A1, 153B1, and the second overlapping part 153A2, 153B2. A recess may be formed.

  In addition, a half cylinder portion 154A and 154B that divides the cylinder portion 52b is formed with a lock portion 160A at one end of the half cylinder portion 154A opposite to the hinge portion 53, and at the other half cylinder portion 154B. Since the lock receiving portion 160B is formed at the end opposite to the hinge portion 53, the divided portions 152A and 152B are maintained in the combined state by the lock structure of the lock portion 160A and the lock receiving portion 160B. can do. Moreover, it can suppress that the accommodation space between the 1st protector part 40 and the 2nd protector part 50 becomes narrow according to the unification maintenance structure, and an outward protrusion is formed in the plate-shaped part 52a. Can be suppressed.

  In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.
