The hole portion 14 of the first engagement portion 13B opens toward the other first engagement portion 13A.

[0023] The second engagement body 20 has a main wall 21, a second side wall 22, and two second engagement portions 23. The main wall 21 is a wall portion that constitutes the bottom wall of the groove portion 2a. The main wall 21 has a substantially flat plate shape. The main wall 21 has a rectangular shape in a plan view. A portion of the main wall 21 of the second engagement body 20 can be overlapped with the main wall 11 of the first engagement body 10. For example, the main wall 21 is overlapped with the main wall 11 so as to cover the clip 6 placed in the insertion hole 11a. The main wall 21 also has a through hole 21b through which the band member 5 is inserted. The through hole 21b of the second engagement body 20 is positioned corresponding to the through hole 11b of the first engagement body 10.

[0024] The main wall 11 of the first engagement body 10 may be provided with a plurality of through holes 11b aligned in the width direction Y. For example, in the protector 1 of this embodiment, the first engagement body 10 and the second engagement body 20 can change the width of the groove portion 2a in three stages. In this case, three through holes 11b may be provided in the main wall 11. The three through holes 11b are arranged so as to face the through hole 21b at each of the three width stages of the groove portion 2a.

[0025] The second side wall 22 stands upright from the edge of the second side Y2 of the main wall 21. The second side wall 22 is a side wall that forms the groove portion 2a and is located at the end of the second side Y2 of the main body 2. When the first engagement portion 13 and the second engagement portion 23 are engaged with each other, the second side wall 22 faces the first side wall 12 in the width direction Y. The second side wall 22 is provided with an engagement portion 22a that corresponds to the engagement portion 33 of the cover 3, and coupling engagement portions 22b and 22c.

[0026] The connecting engagement portions 22b, 22c are engageable with each other. One engagement portion 22b is disposed at an end portion of the second side wall 22 on the first side X1. The other engagement portion 22c is disposed at an end portion of the second side wall 22 on the second side X2. The two engagement portions 22b, 22c engage with each other along the height direction Z.

[0027] The illustrated second engagement portion 23 has a plurality of protrusions 24 protruding in the extension direction X. The plurality of protrusions 24 includes a first protrusion 24a, a second protrusion 24b, and a third protrusion 24c. The plurality of protrusions 24 are arranged side by side in the width direction Y. Of the plurality of protrusions 24, the first protrusion 24a is located farthest from the second side wall 22. Of the plurality of protrusions 24, the third protrusion 24c is located closest to the second side wall 22.

[0028] In the following description, one of the two second engagement portions 23 will be referred to as second engagement portion 23A, and the other of the two second engagement portions 23 will be referred to as second engagement portion 23B. The second engagement portion 23A is disposed on a first side X1 in the extension direction X. The second engagement portion 23B is disposed on a second side X2 in the extension direction X.

[0029] The second engagement portion 23 is configured so that the protrusion 24 protrudes on the side opposite to the other second engagement portion 23. That is, the protrusion 24 of the second engagement portion 23A protrudes in a direction away from the other second engagement portion 23B. The protrusion 24 of the second engagement portion 23B protrudes in a direction away from the other second engagement portion 23A.

[0030] The protrusions 24 of the second engagement portion 23 are insertable into the holes 14 of the first engagement portion 13 along the extension direction X. More specifically, one protrusion 24 of the second engagement portion 23 is engageable with one hole 14 of the first engagement portion 13. For example, the first protrusion 24a is engageable with any one of the holes 14 of the first hole 14a, the second hole 14b, and the third hole 14c. The second protrusion 24b is engageable with the second hole 14b or the third hole 14c. The third protrusion 24c is engageable with the third hole 14c.

[0031] The second engagement body 20 has a flexible portion 25 disposed between the two second engagement portions 23A, 23B. The flexible portion 25 is provided on the main wall 21 and has flexibility. The illustrated flexible portion 25 is molded in the shape of a hinge having a thin portion. The flexible portion 25 may also be a groove extending in the width direction Y.

[0032] The main wall 21 has a first region 211 and a second region 212. The first region 211 is disposed on a first side X1 in the extension direction X with respect to the flexible portion 25. The second region 212 is disposed on a second side X2 in the extension direction X with respect to the flexible portion 25. The flexible portion 25 has high flexibility with respect to the first region 211 and the second region 212. Therefore, the second engagement body 20 can be bent into a substantially V-shape by deforming the flexible portion 25. The protrusion 24 of the second engagement portion 23 is inserted into the hole 14 of the first engagement portion 13 in a bent state of the second engagement body 20. When the shape of the second engagement body 20 returns to a flat plate shape, the engagement of each protrusion 24 with each hole 14 is completed.

[0033] The second side wall 22 of the second engagement body 20 is divided into two regions 221 and 222 with the flexible portion 25 therebetween. The first region 221 is disposed on a first side X1 in the extension direction X with respect to the flexible portion 25. The second region 222 is disposed on a second side X2 in the extension direction X with respect to the flexible portion 25. A gap 22s is provided between the two regions 221 and 222. Dividing the second side wall 22 into the two regions 221 and 222 makes it easy for the second engagement body 20 to deform.

[0034] In the protector 1 of this embodiment, the width Wd1 of the main body 2 changes depending on which of the multiple hole portions 14 the first protrusion 24a engages with. The first protrusion 24a may engage with the first hole portion 14a, as shown by the dashed line in FIG. 4. In this case, the second protrusion 24b engages with the second hole portion 14b, and the third protrusion 24c engages with the third hole portion 14c. FIG. 3 shows the main body 2 formed when the first protrusion 24a engages with the first hole portion 14a. In this case, the width Wd1 of the main body 2 becomes the narrowest of the selectable widths Wd1.

[0035] 5 shows the main body 2 when the first protrusion 24a is engaged with the third hole portion 14c. In this case, the second protrusion 24b and the third protrusion 24c are exposed without being inserted into the hole portion 14. The width Wd1 of the main body 2 shown in FIG. 5 is the widest of the selectable widths Wd1.

[0036] The two engaging bodies 10, 20 may engage with each other with the second protrusion 24b inserted into the third hole 14c. In this case, the first protrusion 24a is inserted into the second hole 14b, and the third protrusion 24c is exposed without being inserted into the hole 14. The width Wd1 of the main body 2 when the second protrusion 24b engages with the third hole 14c is an intermediate size among the selectable widths Wd1.

[0037] As shown in Fig. 6, the first engagement body 10 and the second engagement body 20 engage with each other to form an assembly 2e. The assembly 2e is a member in which one first engagement body 10 and one second engagement body 20 are engaged with each other. The assembly 2e forms a groove portion 2a. The main body 2 may be formed by connecting a plurality of assemblies 2e. As shown in Fig. 6, two assemblies 2e are connected by engaging the engagement portion 12b of one assembly 2e with the engagement portion 12c of the other assembly 2e.

[0038] As shown in FIG. 7 , two adjacent assemblies 2e may be fixed by a band member 5. The band member 5 is, for example, a cable tie. The band member 5 is inserted into the through holes 11b, 21b of one assembly 2e, and then inserted into the through holes 11b, 21b of another assembly 2e to bind the two assemblies together. The band member 5 restricts relative displacement between the two assemblies 2e and can reinforce the connection between the two assemblies 2e. Furthermore, the band member 5 suppresses rattle between the first engagement body 10 and the second engagement body 20 in one assembly 2e, and can firmly connect the two engagement bodies 10, 20.

[0039] As shown in FIG. 8 , a clip 6 is disposed on the main body 2. The main body 2 is fixed to a metal panel or the like by the clip 6.

The engagement portion 61 of the clip 6 is inserted into the insertion hole 11a of the first engagement body 10. The flange portion 62 is locked by the main wall 11 of the first engagement body 10. The flange portion 62 is sandwiched between the main wall 11 of the first engagement body 10 and the main wall 21 of the second engagement body 20. The main wall 21 covers the flange portion 62, thereby suppressing interference between the wire harness W and the flange portion 62.

[0040] As shown in FIG. 9 , the cover 3 is attached to the main body 2 along the height direction Z. The cover 3 has a cover body 31, a pair of side walls 32, and a plurality of engaging portions 33. The cover body 31, the pair of side walls 32, and the engaging portions 33 are, for example, molded integrally. The cover body 31 is a portion that covers the groove portion 2a of the main body 2 and has a generally flat plate shape. The side walls 32 stand upright from the ends of the cover body 31 in the width direction Y. The side walls 32 of the cover 3 face the first side wall 12 and the second side wall 22 of the main body 2 from the outside. The engaging portions 33 of the cover 3 engage with the engaging portions 12a, 22a of the main body 2 to fix the cover 3 to the main body 2.

[0041] In the protector 1 of this embodiment, one cover 3 is attached to one assembly 2e. The cover body 31 extends from one end to the other end of the assembly 2e in the extension direction X, and can cover the entire groove 2a. The cover 3 is attached to the main body 2 after the wire harness W is routed in the groove 2a of the main body 2.

[0042] The protector 1 may have a cover 3 of different widths depending on the width Wd1 of the main body 2. Fig. 10 shows a wide cover 3 that is assembled to a wide main body 2. By assembling the integrally formed cover 3 to the main body 2, the formed tubular portion 4 can have appropriate rigidity.

[0043] As shown in Fig. 11, the wire harness W is routed in the groove portion 2a of the main body 2. In the protector 1 of this embodiment, at least a part of the wire harness W can be pulled out through the gap 22s of the second engaging body 20. For example, as shown in Fig. 11, some of the multiple electric wires in the wire harness W are pulled out to the outside through the gap 22s as branch wires WB. When the main body 2 is composed of multiple assemblies 2e, the wire harness W can be branched in each assembly 2e.
