DETAILED DESCRIPTION OF THE INVENTION

[0011] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0012] The wiring member protector of the present disclosure is as follows.

[0013] (1) A protector for wiring members comprising a first protector part and a second protector part to be combined with the first protector part, wherein the first protector part includes a first base part, and the second protector part includes a second base part and a fixing part to be fixed to a fixing object, wherein the fixing part has a columnar part protruding from the second base part, a retaining projection protruding from the columnar part in a direction intersecting the longitudinal direction of the columnar part, and a disc spring part located on the columnar part closer to the base end than the retaining projection, wherein an insertion hole through which the fixing part can be inserted is formed in the first base part, and wherein the fixing part is inserted into the insertion hole when the second base part is placed on top of the first base part.

[0014] According to the present disclosure, a wiring protector is configured to include a first protector component and a second protector component, and the wiring protector can be fixed to a target object by inserting the fixing portion of the second protector component into an insertion hole formed in the first base and fixing the second protector component to the target object. This eliminates the need to integrally form the fixing portion with the first protector component, and wiring protectors having fixing portions can be easily molded using a mold. Furthermore, the fixing portion can be fixed to the target object using the retaining protrusion and the disc spring portion, so the protector can be securely fixed to the target object.

[0015] (2) In the wiring protector of (1), the first base portion may have an additional fixing portion that is fixed to the fixing object at a position away from the insertion hole.

[0016] As a result, the fixing portion that is fixed to the fixing target is formed on the second protector component, and the additional fixing portion is formed on the first protector component. By forming the portions that are fixed to the fixing target on separate components, the first protector component and the second protector component can be easily molded.

[0017] (3) In the protector for wiring members of (2), the additional fixing portion may have a screw passage hole through which a screw passes, and the additional fixing portion may protrude on the side where the fixing portion protrudes beyond the portion of the first base portion around the insertion hole.

[0018] In this way, even if the additional fixing portion protrudes on the side where the fixing portion protrudes beyond the portion of the first base around the insertion hole, if the fixing portion is formed in the second protector part and the additional fixing portion is formed in the first protector part, each of the first protector part and the second protector part can be easily molded.

[0019] (4) In a protector for a wiring member according to any one of (1) to (3), the insertion hole may be formed to a size that allows the disc spring portion to pass through, and the fixing portion may be inserted into the insertion hole so that the anti-pullout protrusion and the disc spring portion extend beyond the insertion hole when the second base portion is stacked on the first base portion.

[0020] This allows the fixing portion to be fixed to the fixing object by utilizing the retaining protrusion and the disc spring portion that extend beyond the insertion hole.

[0021] (5) In a protector for a wiring member according to any one of (1) to (4), when the anti-pullout protrusion is engaged with the fixed object, the second base may be in contact with the first base from the side opposite the fixed object.

[0022] This allows the second base portion to press the first base portion toward the fixed object.

[0023] (6) In a protector for a wiring member according to any one of (1) to (5), the first base may have a positioning surface that faces at least a portion of the peripheral edge of the second base and positions the second base in at least one direction that intersects with the protruding direction of the fixing portion.

[0024] This makes it difficult for the first base portion and the second base portion to become misaligned.

[0025] (7) In the wiring protector of (6), the first base portion may have a guide surface that is continuous with the positioning surface and is inclined outward in a direction opposite to the direction in which the fixing portion protrudes.

[0026] This makes it easier to position the second base portion inside the positioning surface.

[0027] (8) In a protector for a wiring member according to any one of (1) to (7), the second base may have a locking piece extending along the outward surface of the first base, and the first base may have a locking receiving portion that locks the locking piece to prevent it from coming loose.

[0028] This allows the locking piece to be locked into the lock receiving portion to prevent it from coming off, making it easier to fix the fixing portion to the fixing object in a state where the second base portion is overlapped on the first base portion.

[0029] (9) In a protector for a wiring member according to any one of (1) to (8), the first protector part may include a first protector body, the second protector part may include a second protector body, the first protector body and the second protector body may be combined to form a storage space for storing a wiring member, the first base may extend from the first protector body to the outside of the storage space, and the second base may extend from the second protector body to the outside of the storage space.

[0030] The first protector body forming the storage space for the wiring member can be fixed to a fixed object via the first base, and the second protector body forming the storage space for the wiring member can be fixed to a fixed object via the second base.

[0031] [Details of the embodiments of the present disclosure] Specific examples of the wiring protector of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0032] [Embodiment] A wiring protector according to an embodiment will be described below.

[0033] <Overall structure> Fig. 1 is a perspective view showing a wiring member protector (hereinafter simply referred to as a protector) 20. Fig. 2 is an exploded perspective view showing the protector 20. In Fig. 1, the wiring member 10 protected by the protector 20 is shown by a two-dot chain line.

[0034] The protector 20 includes a first protector component 30 and a second protector component 50. The first protector component 30 and the second protector component 50 are combined together. In other words, the protector 20 is a composite component of the first protector component 30 and the second protector component 50. In this embodiment, the combination of the first protector component 30 and the second protector component 50 forms a space that accommodates and protects at least a portion of the wiring member 10 in the extension direction.

[0035] The wiring member 10 includes at least one electric wire. The wiring member 10 is, for example, a wiring material that connects electrical components mounted on a vehicle. The wiring member 10 may be a wire harness in which a plurality of electric wires are bundled together.

[0036] In this embodiment, the first protector component 30 includes a first protector body 32 and a first base 40. The second protector component 50 includes a second protector body 52, a second base 60, and a fixing portion 70. The first protector component 30 and the second protector component 50 are each a component integrally molded from resin by a mold.

[0037] The first protector body 32 and the second protector body 52 are combined to form an accommodation space AS for accommodating the wiring member 10.

[0038] In this embodiment, the first protector body 32 includes a bottom 33 and two wall portions 34, 35. The bottom portion 33 is formed in a long, narrow plate shape. The bottom portion 33 may be curved in at least one of its width direction and thickness direction. The two wall portions 34, 35 rise from both side edges of the bottom portion 33 toward one main surface of the bottom portion 33. In this embodiment, one wall portion 34 is higher than the other wall portion 35. An extension piece 33p for binding and fixing the wiring member 10 may be formed on an end of the bottom portion 33 or the wall portions 34, 35.

[0039] The second protector body 52 includes a ceiling portion 53 and an upper wall portion 54. The ceiling portion 53 is formed in the shape of a long, narrow plate. The ceiling portion 53 may be curved in at least one of the width direction and the thickness direction. The ceiling portion 53 is a portion disposed opposite the bottom portion 33.

[0040] An upper wall portion 54 extends from one side edge of the ceiling portion 53. In this embodiment, the upper wall portion 54 extends toward one main surface of the ceiling portion 53 while forming an obtuse angle with respect to the ceiling portion 53.

[0041] When the first protector body 32 and the second protector body 52 are combined, the upper edge of the wall portion 34 abuts against the side edge of the ceiling portion 53 opposite the upper wall portion. Also, the upper edge of the wall portion 35 abuts against the lower edge of the upper wall portion 54. Engageable engagement recesses 36 and engagement protrusions 56 are formed in the abutting portions of the first protector body 32 and the second protector body 52, and the combined state of the first protector body 32 and the second protector body 52 is maintained by the engagement of the engagement recesses 36 with the engagement protrusions 56. When the first protector body 32 and the second protector body 52 are combined, an elongated storage space AS is formed that is surrounded by the bottom portion 33, the walls 34, 35, the ceiling portion 53, and the upper wall portion 54. The storage space AS is open on both end sides of the protector 20, and a portion of the wiring member 10 in the longitudinal direction is stored in the storage space AS, with both ends of the wiring member 10 extending outward through the openings on both end sides of the protector 20.

[0042] The configuration in which the first protector body 32 and the second protector body 52 form the accommodation space AS is not limited to the above example. For example, one of the first protector body and the second protector body may form a long, narrow space that is open at both ends and at the top, and the other may function as a plate-like lid that closes the top opening. Also, the first protector body and the second protector body may be configured to be separated in the extension direction of the wiring member.

[0043] The first base portion 40 extends from the first protector body 32 to the outside of the accommodation space AS. The second base portion 60 extends from the second protector body 52 to the outside of the accommodation space AS.

[0044] In this embodiment, the first base portion 40 protrudes outward from the upper edge of the wall portion 34. The first base portion 40 may be perpendicular to the wall portion 34. The second base portion 60 protrudes outward from the side edge of the ceiling portion 53 opposite the upper wall portion 54. The second base portion 60 may be parallel to the ceiling portion 53 and extend outward from the ceiling portion 53.

[0045] The first base portion 40 is formed in a plate shape. An insertion hole 42h is formed in the first base portion 40.

[0046] The second base portion 60 is formed in a plate shape that can be placed on the first base portion 40 .

[0047] The fixing portion 70 is a portion that is fixed to a fixing target of the protector 20. The fixing portion 70 protrudes from the first base portion 40 toward the first base portion 40.

[0048] With the first protector component 30 and the second protector component 50 combined, the second base component 60 is placed on the first base component 40. In this state, the fixing component 70 is inserted into the insertion hole 42h. The fixing component 70 protrudes from the insertion hole 42h to the opposite side from the second base component 60, and is fixed to a fixing object.

[0049] <About the fixing structure> The first base 40, the second base 60, and the fixing portion 70 will be described in more detail. Fig. 3 is an exploded perspective view showing the first base 40, the second base 60, and the fixing portion 70. Fig. 4 is a plan view showing the first base 40, the second base 60, and the fixing portion 70. Fig. 5 is a side view showing the first base 40, the second base 60, and the fixing portion 70. Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 5.

[0050] The first base portion 40 is formed in the shape of a long, narrow plate extending in a direction along the upper edge of the wall portion 34. One end of the first base portion 40 is located in the middle of the wall portion 34 in the longitudinal direction. The one end of the first base portion 40 is formed so that the length of its projection from the upper edge of the wall portion 34 gradually decreases. The other end of the first base portion 40 projects from the upper edge of the wall portion 34 in the longitudinal direction of the upper edge.

[0051] The first base portion 40 may be formed with ribs 40g for reinforcing while reducing the thickness of the first base portion 40. In this embodiment, the first base portion 40 has ribs 40g formed on the portion opposite to the bottom portion 33, which intersect vertically and horizontally.

[0052] An insertion hole 42h is formed in the longitudinal middle portion of the first base portion 40. The insertion hole 42h is formed so that the fixing portion 70 can be inserted therethrough. In the present embodiment, the insertion hole 42h is set to a size that allows the disc spring portion 76 of the fixing portion 70 to pass through. For example, the inner diameter of the insertion hole 42h may be the same as the maximum diameter of the disc spring portion 76, or may be larger than this maximum diameter.

[0053] The second base portion 60 partially protrudes from the side edge of the ceiling portion 53 of the second protector body 52 opposite to the upper wall portion 54. The second base portion 60 is formed in the shape of a rectangular plate with a width smaller than the longitudinal dimension of the first base portion 40. The protruding length of the second base portion 60 from the ceiling portion 53 is set to a size that reaches the outward side edge of the first base portion 40. A lightening recess may be formed in the second base portion 60.

[0054] The fixing portion 70 includes a columnar portion 72 , a retaining projection 74 , and a disc spring portion 76 .

[0055] The columnar portion 72 is formed in an elongated shape that protrudes from the second base portion 60 toward the first base portion 40. For example, the columnar portion 72 is formed in the middle of the second base portion 60 in the width direction and at a position closer to the tip. The length of the columnar portion 72 is greater than the thickness of the first base portion 40, and can penetrate through the first base portion 40.

[0056] The retaining projection 74 is a portion that projects from the columnar portion 72 in a direction intersecting the longitudinal direction of the columnar portion 72, and is a portion that engages with the fixed object 100 to prevent it from coming off.

[0057] The fixed object 100 is, for example, a part of the body of a vehicle or a bracket attached to the body. The fixed object 100 is formed in a plate shape, and a locking hole 102h is formed in the fixed object 100. The retaining protrusion 74 can be locked in the locking hole 102h to prevent it from coming off.

[0058] For example, the retaining projection 74 includes a pair of elastic pieces 74p cantilevered from the tip to the base end of the columnar portion 72. The elastic pieces 74p are inclined so that the distance from the columnar portion 72 increases as they approach the base end of the columnar portion 72. A partial recess 74pg is formed in the tip of each elastic piece 74p on the side opposite the columnar portion 72. The retaining projection may have a tree-like retaining shape in which multiple dish-shaped portions are formed at intervals.

[0059] The disc spring portion 76 is located closer to the base end of the columnar portion 72 than the retaining projection 74. The disc spring portion 76 is formed in a disc spring shape that gradually widens toward the tip end of the columnar portion 72. The disc spring portion may widen in a circular or elliptical shape.

[0060] With the second base portion 60 placed on top of the first base portion 40, the fixing portion 70 is inserted into the insertion hole 42h. Then, the retaining projection 74 and the disc spring portion 76 extend beyond the insertion hole 42h. More specifically, the entire retaining projection 74 extends beyond the insertion hole 42h. The peripheral portion of the disc spring portion 76 on the retaining projection 74 side extends beyond the insertion hole 42h. The portion of the disc spring portion 76 that is connected to the columnar portion 72 may remain within the insertion hole 42h, or may extend beyond the insertion hole 42h.

[0061] The portion of the fixing part 70 that has come out of the second base part 60 is inserted into the locking hole 102h of the fixing object 100. As described above, the peripheral edge of the retaining protrusion 74 and the disc spring part 76 has come out of the insertion hole 42h, and therefore the fixing part 70 is fixed to the fixing object 100 by utilizing the peripheral edge of the retaining protrusion 74 and the disc spring part 76.

[0062] Specifically, when the retaining projection 74 is inserted into the locking hole 102h, the outward surfaces of the pair of elastic pieces 74p come into contact with the periphery of the locking hole 102h and are elastically deformed inward. When the outward surfaces of the pair of elastic pieces 74p clear the locking hole 102h, the pair of elastic pieces 74p attempt to return to their original shape due to elastic restoring force. Then, the recesses 74pg at the tips of the pair of elastic pieces 74p are locked against the periphery of the locking hole 102h from the side opposite the first base portion 40 to prevent the pair of elastic pieces 74p from coming out.

[0063] In this state, the disc spring portion 76 elastically deforms, and the peripheral edge of the disc spring portion 76 comes into contact with the surface around the locking hole 102h of the fixed object 100 from the first base portion 40 side. As a result, the peripheral edge of the locking hole 102h of the fixed object 100 is sandwiched between the tip ends of the pair of elastic pieces 74p and the disc spring portion 76, and the fixed portion 70 is firmly fixed to the fixed object 100.

[0064] With the retaining protrusion 74 locked to the fixed object 100, it is preferable that the second base 60 contacts the second base 60 from the side opposite to the fixed object 100. This prevents the second base 60 from moving in a direction away from the first base 40.

[0065] The first base portion 40 preferably has positioning surfaces 44sf, 44hf that face at least a portion of the periphery of the second base portion 60 and position the second base portion 60 in at least one direction that intersects with the protruding direction of the fixing portion 70.

[0066] In this embodiment, positioning ribs 44s, 44h protrude from the surface of the first base portion 40 facing the second base portion 60 at positions surrounding both sides and the tip end of the second base portion 60. The positioning ribs 44s, 44h also function as ribs for reinforcing the strength of the first base portion 40.

[0067] The pair of positioning ribs 44s are located on the outer sides of both widthwise edges of the second base portion 60. The insertion hole 42h is located between the pair of positioning ribs 44s. The diameter of the insertion hole 42h is larger than the width of the second base portion 60. For this reason, the portion of the positioning rib 44s that is intermediate in the extension direction and closer to the tip is formed to be curved in an arc that convex outward. The insertion hole 42h is formed between the pair of positioning ribs 44s and in the arc-shaped curved portion.

[0068] The inward surfaces of the pair of positioning ribs 44s excluding the arc-shaped curved portions are positioning surfaces 44sf that face opposite edges on both sides in the width direction of the second base 60. The spacing between the positioning ribs 44s may be the same as the width of the second base 60, or may be greater than the width of the second base 60 as long as rattle in the width direction of the second base 60 can be prevented.

[0069] The positioning rib 44h is located outside the outer edge in the protruding direction of the second base portion 60. The positioning rib 44h also runs along the tip edge of the first base portion 40. The inward surface of the positioning rib 44h is a positioning surface 44hf that faces the edge portion on the tip side of the second base portion 60.

[0070] Because the second base 60 is disposed at a position surrounded by the pair of positioning surfaces 44sf and 44hf, the first base 40 and the second base 60 are less likely to become misaligned in a direction perpendicular to their thickness directions. With the second base 60 disposed at a position surrounded by the pair of positioning surfaces 44sf and 44hf, the second base 60 contacts the bottom surface of the first base 40 surrounded by the pair of positioning surfaces 44sf and 44hf.

[0071] The first base portion 40 has guide surfaces 44sg, 44hg that are continuous with the positioning surfaces 44sf, 44hf and are inclined outward in the direction opposite to the direction in which the fixing portion 70 protrudes.

[0072] In this embodiment, the tip portions of the inwardly facing surfaces of the pair of positioning ribs 44s are formed as outwardly inclined guide surfaces 44sg, and the tip portions of the inwardly facing surfaces of the positioning ribs 44h are formed as outwardly inclined guide surfaces 44hg.

[0073] Therefore, when the second base portion 60 is to be placed on the first base portion 40, the second base portion 60 is guided by the guide surfaces 44sg and 44hg, and is smoothly guided into the space surrounded by the positioning surfaces 44sf and 44hf.

[0074] The second base portion 60 has a locking piece 68, and the first base portion 40 has a locking receiving portion 48.

[0075] A protruding portion is formed at the tip of the second base portion 60, which is located on the tip of the positioning rib 44h, and the locking piece 68 extends from this protruding portion along the outward surface of the first base portion 40. A locking protrusion 68p is formed at the tip of the locking piece 68. The locking protrusion 68p is formed to protrude from the tip of the outward surface of the locking piece 68. The locking protrusion 68p is formed in a shape that gradually decreases in height toward the tip of the locking piece 68.

[0076] The lock receiving portion 48 is formed to protrude from the tip end portion of the first base portion 40. A slit-shaped locking hole 48s into which the locking piece 68 can be inserted is formed between the lock receiving portion 48 and the tip outward surface of the first base portion 40. The lock receiving portion 48 also has a receiving piece 48p that faces the outward surface of the locking piece 68. The receiving piece 48p is a rectangular plate-shaped piece that extends in the protruding direction of the fixing portion 70 and is inclined so as to approach the tip outward surface of the first base portion 40 as it protrudes.

[0077] When the second base 60 is placed on top of the first base 40, the locking piece 68 on the tip side of the second base 60 is inserted into the locking hole 48s of the locking receiving portion 48 on the tip side of the first base 40. When the locking protrusion 68p passes the tip of the receiving piece 48p, the receiving piece 48p is locked with the locking protrusion 68p, and the locking piece 68 is locked to the locking receiving portion 48 to prevent it from coming off.

[0078] The first base 40 has an additional fixing part 45 that is fixed to the fixing object 100 at a location separate from the fixing part 70. The additional fixing part 45 is located away from the fixing part 70, and is fixed to the fixing object 100 at a location separate from the fixing part 70.

[0079] In this embodiment, the additional fixing portion 45 is located at an end of the first base portion 40 that protrudes outward from the first protector body 32. The additional fixing portion 45 has a screw passing hole 45S through which the screw 110 passes. For example, the first base portion 40 has an embedded collar 40c, and a hole formed in the collar serves as the screw passing hole 45S. The screw passing hole 45S may be an elongated hole or a round hole.

[0080] The additional fixing portion 45 protrudes further from the portion of the first base 40 around the insertion hole 42h toward the side where the fixing portion 70 protrudes. The surface of the additional fixing portion 45 on the side where the fixing portion 70 protrudes protrudes to match the position of the surface of the fixed object 100 that the additional fixing portion 45 faces. In this embodiment, the additional fixing portion 45 protrudes via a step portion 45a.

[0081] A screw 110 protrudes from a portion of the fixed object 100 to which the additional fixing portion 45 is fixed. The screw 110 may be, for example, a bolt welded to the fixed object 100. With the first base portion 40 placed on the fixed object 100, the screw 110 is passed through the screw passing hole 45S. In this state, a nut N is screwed onto the screw 110. As the nut N is screwed onto the screw 110, the additional fixing portion 45 is sandwiched between the fixing surface of the fixed object 100 and the nut N. As a result, the additional fixing portion 45 is fixed to the fixed object 100 using the fixing surface of the fixed object 100 as a reference.

[0082] Because the additional fixing part 45 is sandwiched between the fixing surface of the fixed object 100 and the nut N, it is easy to tighten the nut N until a predetermined torque is generated, making torque management easy. Furthermore, if the fixed object 100 has a metal collar 40c, it is easy to fix the additional fixing part 45 to the fixed object 100 with a relatively large torque.

[0083] The fixing portion 70 of the second base 60 passes through the insertion hole 42h of the first base 40 and protrudes further toward the fixed object 100 than the second base 60. The retaining protrusion 74 is inserted into the locking hole 102h and is locked into the locking hole 102h, and the disc spring portion 76 comes into contact with the portion of the fixed object 100 around the locking hole 102h. This fixes the fixing portion 70 to the fixed object 100.

[0084] Here, let us consider a case where the first base portion 40 is formed with the fixing portion 70 and the additional fixing portion 45.

[0085] In this case, since the fixing part 70 is configured to sandwich the fixed object 100 between the disc spring part 76 and the retaining protrusion 74, the peripheral edge of the disc spring part 76 is located away from the underside of the first base part 40. In other words, it is difficult to bring the part of the first base part 40 near the fixing part 70 into contact with the fixed object 100.

[0086] In order to firmly position the first base 40 relative to the fixed object 100, it is conceivable to bring the additional fixing portion 45 into contact with the fixed object 100. To achieve this, it is conceivable to make the additional fixing portion 45 protrude beyond the portion of the first base 40 surrounding the fixing portion 70 and bring it into contact with the fixed object 100. For example, it is conceivable to align the position of the surface of the additional fixing portion 45 facing the fixed object 100 and the position of the peripheral edge of the disc spring portion 76 on the same plane.

[0087] The fixed portion 70 has a configuration in which a pair of elastic pieces 74p protrude from a columnar portion 72. Therefore, in order to mold the fixed portion 70, it is conceivable to mold the fixed portion 70 using a mold that is divided by a plane that includes the columnar portion 72 and the pair of elastic pieces 74p. In this case, since the additional fixed portion 45 protrudes on the same side as the fixed portion 70, the portion of the fixed portion 70 that is on the base end side of the protruding surface of the additional fixed portion 45 becomes a so-called undercut, making it difficult to mold with a mold.

[0088] Therefore, as in this embodiment, the additional fixing portion 45 is set on the first base portion 40, and the fixing portion 70 is set on the second base portion 60 that is overlaid on the first base portion 40. This allows the fixing portion 70 to be easily molded without being restricted by the additional fixing portion 45.

[0089] <Effects, etc.> According to the protector 20 configured as described above, the wiring protector 20 includes the first protector component 30 and the second protector component 50, and the fixing portion 70 of the second protector component 50 is inserted into the insertion hole 42h formed in the first base 40 to fix the protector 20 to the fixing object 100, thereby fixing the protector 20 to the fixing object 100. This eliminates the need to integrally form the fixing portion 70 with the first protector component 30, and the protector 20 having the fixing portion 70 can be easily molded using a mold. Furthermore, the fixing portion 70 can be fixed to the fixing object 100 using the retaining projection 74 and the disc spring portion 76, so the protector 20 can be securely fixed to the fixing object 100.

[0090] Furthermore, since the mold forming restrictions on the first protector component 30 can be reduced, the degree of freedom in the shape of the protector 20 is increased, which increases the degree of freedom in the layout of the vehicle and the layout of the wire harness.

[0091] Furthermore, the fixing portion 70 is formed on the second protector component 50, and the additional fixing portion 45 is formed on the first protector component 30. By forming the portions that are fixed to the fixing target 100 on separate components, the first protector component 30 and the second protector component 50 can be easily molded by die molding.

[0092] In this case, for example, even if the first base 40 has an additional fixing portion 45 that protrudes on the side where the fixing portion 70 protrudes, each of the first protector part 30 and the second protector part 50 can be easily molded.

[0093] The additional fixing portion may be fixed to the fixing object by other configurations. For example, a screw may be protruding from the additional fixing portion, and a nut may be fastened to the fixing object with the screw inserted through the fixing object.

[0094] Furthermore, the insertion hole 42h is formed to a size that allows the disc spring portion 76 to pass through, and the fixing portion 70 is inserted into the screw passing hole 45S so that the retaining protrusion 74 and the disc spring portion 76 extend beyond the insertion hole 42h when the second base portion 60 is placed on the first base portion 40. Therefore, the fixing portion 70 can be fixed to the fixing object 100 by utilizing the retaining protrusion 74 and the disc spring portion 76 that extend beyond the insertion hole 42h.

[0095] It is not essential that the protector 20 has the above configuration. For example, the disc spring portion 76 may remain in the insertion hole 42h, and the fixed object 100 may partially enter the insertion hole 42h and come into contact with the disc spring portion 76.

[0096] Furthermore, the second base portion 60 comes into contact with the first base portion 40 from the side opposite to the fixed object 100, so that the second base portion 60 can press the first base portion 40 toward the fixed object 100 side.

[0097] Furthermore, because the first base portion 40 has the positioning surfaces 44sf, 44hf, it is difficult for the first base portion 40 and the second base portion 60 to become misaligned. Therefore, for example, by fixing the fixing portion 70 to the fixing object 100, it is easy to position the first protector component 30 and the second protector component 50 to the fixing object 100.

[0098] Furthermore, since the first base portion 40 has the guide surfaces 44sg and 44hg, the guide surfaces 44sg and 44hg make it easy to guide the second base portion 60 into the positioning surfaces 44sf and 44hf.

[0099] Furthermore, since the second base 60 has a locking piece 68 and the first base 40 has a locking receiving portion 48, the locking piece 68 is locked into the locking receiving portion 48 to prevent it from coming loose, making it easy to fix the fixing portion 70 to the fixing object 100 when the second base 60 is stacked on top of the first base 40.

[0100] Furthermore, the first protector component 30 includes a first protector body 32, and the second protector component 50 includes a second protector body 52. ​​The first protector body 32 and the second protector body 52 are combined to form an accommodation space AS that accommodates the wiring member 10. Therefore, the first protector body 32 that forms the accommodation space AS can be fixed to the fixed object 100 via the first base 40, and the second protector body 52 that forms the accommodation space AS can be fixed to the fixed object 100 via the second base 60. The protector 20 as a whole can be firmly fixed to the fixed object 100 at multiple locations.

[0101] It is also possible to have a configuration in which only one of the first protector component 30 and the second protector component 50 forms a space for accommodating the wiring member, and the other does not form such a space.

[0102] The configurations described in the above embodiment and modifications can be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
