[0002] As an example of a technology relating to a conventional wire harness protector, Patent Document 1 discloses a protector including a base having a storage space for storing wiring material to be routed to a vehicle, and a cover attached to the base so as to cover the storage space from one side in the stacking direction. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2022-143606 A Summary of the Invention [Problem to be solved by the invention]
[0004] However, in the wire harness described in the above-mentioned Patent Document 1, for example, the protector may be installed vertically depending on the mounting requirements of the vehicle, and in this case, there is a risk that grease or the like applied inside the storage space may leak to the outside through the gap between the base and the cover.
[0005] The present invention has been made in consideration of the above circumstances, and has an object to provide a protector and a wire harness that can suppress leakage of grease. [Means for solving the problem]
[0006] In order to achieve the above object, a protector according to the present invention comprises a base having a base-side bottom wall and a base-side peripheral wall protruding from a peripheral portion of the base-side bottom wall to one side in a stacking direction intersecting with the base-side bottom wall, the base having an accommodation space inside the base-side peripheral wall for accommodating wiring material to be routed to a vehicle, a cover having a cover-side bottom wall opposed to the base-side bottom wall and a cover-side peripheral wall protruding from a peripheral portion of the cover-side bottom wall to the other side in the stacking direction, the cover being assembled to the base so as to cover the accommodation space from one side in the stacking direction, and the base and the cover having a connector that communicates the accommodation space with the outside and allows the wiring material to be introduced into the accommodation space or drawn out of the accommodation space. a pair of openings are provided through the base and the cover, the cover-side peripheral wall includes a cover-side first peripheral wall located below in a vertical direction intersecting the stacking direction, an arc-shaped curved portion is provided at an inner corner between the cover-side first peripheral wall and the cover-side bottom wall, the base-side peripheral wall includes a base-side first peripheral wall located below in the vertical direction and overlapped inside the cover-side first peripheral wall, a first thickness along the vertical direction at a tip end of the base-side first peripheral wall is thinner than a second thickness along the vertical direction at a base end of the base-side first peripheral wall, and the base and the cover are assembled with the tip end of the base-side first peripheral wall riding on the curved portion and in close contact with the cover-side bottom wall. Effect of the Invention
[0007] In the protector and the wire harness according to the present invention, the first thickness in the vertical direction at the tip end of the base-side first peripheral wall is configured to be thinner than the second thickness in the vertical direction at the base end of the base-side first peripheral wall, and the base and the cover are assembled in a state in which the tip end of the base-side first peripheral wall rides on the curved surface portion and is in close contact with the cover-side bottom wall. With this configuration, the protector and the wire harness can, for example, assemble the base and the cover by relatively easily deforming the tip end, which is thinner than the base end of the base-side first peripheral wall, when assembling the base and the cover, and thus can increase the adhesion between the tip end of the base-side first peripheral wall and the cover-side bottom wall to close the gap between the tip end and the cover-side bottom wall. As a result, the protector and the wire harness have the effect of suppressing leakage of grease applied in the housing space. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially the same. Note that in this specification, ordinal numbers are used only to distinguish between parts, members, parts, positions, directions, etc., and do not indicate order or priority.
[0010] [Embodiment] FIG. 1 is a perspective view of a wire harness WH to which a protector 1 according to an embodiment is applied. The protector 1 of the present embodiment shown in FIG. 1 is incorporated into the wire harness WH to be wired in a vehicle. Here, the wire harness WH is, for example, a bundle of wiring materials W used for power supply and signal communication to connect each device mounted on a vehicle, and the wiring material W is connected to each device by a connector or the like. The wire harness WH of the present embodiment includes a wiring material W having conductivity and a protector 1 that protects the wiring material W. The protector 1 is, for example, a part of the wiring material W to be wired in a sliding seat or a sliding door (not shown) mounted on a vehicle, which is housed therein as an excess part to protect it. In addition, the wire harness WH may be configured to include various other components such as a corrugated tube, a grommet, an electrical connection box, a fixture, and a connector.
[0011] In the following description, among the first, second, and third directions intersecting each other, the first direction is referred to as the "extension direction X", the second direction is referred to as the "stacking direction Y", and the third direction is referred to as the "vertical direction Z". Here, the extension direction X, the stacking direction Y, and the vertical direction Z are approximately perpendicular to each other. The extension direction X typically corresponds to the longitudinal direction of the protector 1, the pull-out direction (insertion direction) of the wiring material W with respect to the protector 1, and the like, and is along the vehicle front-rear direction. The stacking direction Y typically corresponds to the stacking direction of the base 10 and the cover 20 in the protector 1, which will be described later, the thickness direction of the protector 1, and the like, and is along the vehicle width direction. The vertical direction Z typically corresponds to the width direction (height direction) of the base 10 and the cover 20 in the protector 1, and the like, and is along the vehicle up-down direction. In addition, unless otherwise specified, each direction used in the following description will be described as a direction in a state in which the protector 1 is assembled to the vehicle.
[0012] The wiring material W supplies electric power to an electrical device provided in a sliding seat in a vehicle, for example. The wiring material W includes, for example, an electric wire bundle in which a plurality of electric wires are bundled together, and a corrugated tube as a cylindrical exterior material that covers the electric wire bundle. The wiring material W has relatively high flexibility and good bendability in an installed state in which the corrugated tube is attached to the electric wire bundle. In the wiring material W of this embodiment, when the wiring material W is bent by applying an external force from a natural state (approximately straight state) in which no external force is applied in an installed state in which the corrugated tube is attached to the electric wire bundle, the bent portion elastically deforms, and an elastic reaction force is generated in the bent portion, which tends to return to the original state.
[0013] With a portion of the wiring material W housed in a housing space 4 (see FIG. 2) provided inside the protector 1, a portion of the wiring material W is introduced inside the protector 1 with one sliding movement of the sliding seat in one of the sliding directions, and is drawn out to the outside of the protector 1 with the other sliding movement of the sliding seat. One end of the wiring material W is electrically connected to an electrical component provided in the sliding seat, and the other end is electrically connected to a battery or the like mounted on the vehicle.
[0014] The protector 1 extends along the extension direction X, and is provided with a pair of openings 2, 3 at one end of the extension direction X. The wiring material W is inserted through each of the openings 2, 3 in a state in which a part of the wiring material W is housed inside the protector 1. In the protector 1, the wiring material W is introduced from one opening 2 as the slide sheet moves in one of the sliding directions, and the wiring material W is drawn out from the opening 2 as the slide sheet moves in the other sliding direction. In a state in which a part of the wiring material W is housed inside the protector 1, one end of the wiring material W is configured to be able to be inserted and removed from the inside and outside of the protector 1 via the opening 2.
[0015] Meanwhile, the wiring material W is partially housed inside the protector 1, and the other end is bound to a part of the protector 1 with optional tape, a cable tie or the like at a position protruding outward from the opening 3, restricting insertion and removal of the protector 1 through the opening 3. The protector 1 is installed vertically with the width direction (short side direction) of the base 10 and cover 20 (described later) aligned along the vertical direction Z, and is fastened to the vehicle body via a pair of mounting parts 24, 26 provided at both ends in the extension direction X.
[0016] FIG. 2 is an exploded perspective view of the protector 1, and FIG. 3 is a cross-sectional view of the protector 1. As shown in FIGS. 2 and 3, the protector 1 includes, for example, a base 10 and a cover 20. The base 10 and the cover 20 are formed of, for example, synthetic resin having insulating properties. The cover 20 is assembled to the base 10 in a stacked state on one side of the stacking direction Y. The base 10 and the cover 20 are formed separately from each other, and are integrated with each other by a locking mechanism 30 including a locking portion 31 and a locked portion 32, which will be described later. The protector 1 is formed into a substantially rectangular parallelepiped shape as a whole by assembling the base 10 and the cover 20 to each other.
[0017] The base 10 has, for example, a base-side bottom wall 11 and a base-side peripheral wall 12 provided on the peripheral portion of the base-side bottom wall 11. The base-side bottom wall 11 and the base-side peripheral wall 12 are structures for partitioning the above-mentioned storage space 4 as the internal space of the protector 1. The storage space 4 is a space in which the wiring material W is stored. The base-side bottom wall 11 is formed, for example, in a flat plate shape and extends along the extension direction X. A plurality of beads 13 protruding along the stacking direction Y are provided on the outer surface of the base-side bottom wall 11. The plurality of beads 13 are for reinforcing the base 10 and are formed, for example, in a lattice shape extending along the extension direction X and the vertical direction Z.
[0018] The base-side peripheral wall 12 protrudes from the peripheral edge of the base-side bottom wall 11 to one side in the stacking direction Y. The base-side peripheral wall 12 includes, for example, a base-side first peripheral wall 12a located on the lower side in the vertical direction Z, a base-side second peripheral wall 12b located on the upper side in the vertical direction Z, and a base-side third peripheral wall 12c located on the other end side in the extension direction X (opposite the openings 2 and 3). The base-side first peripheral wall 12a and the base-side second peripheral wall 12b extend linearly along the extension direction X. The base-side third peripheral wall 12c is connected to the other end portions in the extension direction X of the base-side first peripheral wall 12a and the base-side second peripheral wall 12b, and is curved in an arc shape (semicircular shape) in a convex state toward the other side in the extension direction X.
[0019] Further, at one end of the base 10 in the extending direction X, a wiring routing portion 15 through which the wiring material W is routed is provided. The wiring routing portion 15 is connected to one end of the base-side first peripheral wall 12a in the extending direction X, and is curved in an arc shape (semicircular shape) in a state of being convex toward one side in the extending direction X. The wiring routing portion 15 has a substantially U-shaped cross section that opens toward one side (the cover 20 side) in the stacking direction Y, and is overlapped in the stacking direction Y with a wiring routing portion 25 on the cover 20 side described later. The internal space of the pair of wiring routing portions 15, 25 functions as an insertion space through which the wiring material W is inserted, and one end of the insertion space communicates with the above-mentioned storage space 4, and the other end forms the above-mentioned opening 2.
[0020] A pair of mounting portions 14, 16 are provided at both ends of the base 10 in the extending direction X. The mounting portion 14 is provided in a state of protruding downward in the vertical direction Z from the base-side third peripheral wall 12c, and is overlapped in the stacking direction Y with a mounting portion 24 on the cover 20 side described later. The mounting portions 14, 24 are provided with mounting holes 14a, 24a through which fastening members such as bolts for fastening the protector 1 to the vehicle body penetrate in the stacking direction Y. The mounting portion 16 is provided at one end of the base-side bottom wall 11 in the extending direction X, and is overlapped in the stacking direction Y with a mounting portion 26 on the cover 20 side described later. The mounting portions 16, 26 are provided with mounting holes 16c, 26c through which fastening members such as bolts for fastening the protector 1 to the vehicle body penetrate in the stacking direction Y.
[0021] The cover 20 is assembled to the base 10 and covers (closes) the storage space 4 in the base 10. The cover 20 has, for example, a cover-side bottom wall 21 and a cover-side peripheral wall 22 provided on the peripheral portion of the cover-side bottom wall 21. The cover-side bottom wall 21 and the cover-side peripheral wall 22 are structures for partitioning the above-mentioned storage space 4 as the internal space of the protector 1. The cover-side bottom wall 21 is formed, for example, in a flat plate shape and extends along the extension direction X so as to face the base-side bottom wall 11. The outer surface of the cover-side bottom wall 21 is provided with a plurality of beads 23 (see FIG. 1 ) protruding along the stacking direction Y. The plurality of beads 23 are for reinforcing the cover 20 and are formed, for example, in a lattice shape extending along the extension direction X and the vertical direction Z.
[0022] The cover-side peripheral wall 22 protrudes from the peripheral edge of the cover-side bottom wall 21 to the other side in the stacking direction Y. The cover-side peripheral wall 22 includes, for example, a cover-side first peripheral wall 22a located on the lower side in the vertical direction Z, a cover-side second peripheral wall 22b located on the upper side in the vertical direction Z, and a cover-side third peripheral wall 22c located on the other end side (opposite the openings 2 and 3) in the extension direction X. The cover-side first peripheral wall 22a and the cover-side second peripheral wall 22b extend linearly along the extension direction X. The cover-side first peripheral wall 22a is overlapped on the outside of the base-side first peripheral wall 12a, and the cover-side second peripheral wall 22b is overlapped on the outside of the base-side second peripheral wall 12b. The cover-side first peripheral wall 22a faces the floor surface of the vehicle.
[0023] The cover-side third peripheral wall 22c is connected to the other end 22a2 of the cover-side first peripheral wall 22a in the extension direction X and the other end of the cover-side second peripheral wall 22b in the extension direction X, and is curved in an arc shape (semicircular shape) in a state of being convex toward the other side in the extension direction X. The cover-side third peripheral wall 22c is overlapped on the outside of the base-side third peripheral wall 12c. In addition, an attachment portion 24 is provided on the cover-side third peripheral wall 22c, i.e., the other end of the cover 20 in the extension direction X. The attachment portion 24 protrudes downward in the vertical direction Z from the cover-side third peripheral wall 22c.
[0024] In addition, a wiring routed portion 25 through which the wiring material W is routed is provided at one end of the extension direction X of the cover 20. The wiring routed portion 25 is connected to one end 22a1 of the extension direction X of the cover-side first peripheral wall 22a, and is curved in an arc shape (semicircular shape) in a state of being convex toward one side of the extension direction X. The wiring routed portion 25 has a substantially U-shaped cross section that opens toward the other side (base 10 side) of the stacking direction Y, and is overlapped with the wiring routed portion 15 on the base 10 side in the stacking direction Y to form an insertion space portion through which the wiring material W is inserted together with the wiring routed portion 15. The opening 2 is provided at the end of the wiring routed portions 15, 25 opposite to the storage space portion 4, and the opening 3 is provided near the end of the wiring routed portions 15, 25 on the storage space portion 4 side.
[0025] Moreover, an attachment portion 26 is provided at one end of the extension direction X of the cover 20. The attachment portion 26 is overlapped in the stacking direction Y with the attachment portion 16 on the base 10 side described above. The attachment portion 26 is provided, for example, in a state in which it protrudes in a convex shape from the cover-side bottom wall 21 to the other side (base 10 side) in the stacking direction Y. As a result, a step portion 26b in the stacking direction Y is formed between the cover-side bottom wall 21 and a top portion 26a (convex portion) of the attachment portion 26. The side surface of the step portion 26b is formed in an arc shape along a folded portion W1 (see FIG. 2) of the wiring material W, which will be described later.
[0026] The storage space 4 is formed in the protector 1 and communicates with the outside through a pair of openings 2 and 3. When viewed from the stacking direction Y, the wiring material W arranged in the storage space 4 has straight portions arranged on both sides of the vertical direction Z, and a folded portion W1 that connects the straight portions and is folded back is arranged at the center of the vertical direction Z. The folded portion W1 is a portion of the wiring material W accommodated in the storage space 4 that is folded back in a U-shape from one side to the other side in the extension direction X. One of the straight portions is a portion of the wiring material W accommodated in the storage space 4 that is connected to one end of the folded portion W1 and extends along the extension direction X so as to face the base side first peripheral wall 12a and the cover side first peripheral wall 22a. The other straight portion is a portion of the wiring material W accommodated in the accommodation space 4 that is connected to the other end of the folded portion W1 and extends along the extension direction X so as to face the base side second peripheral wall 12b and the cover side second peripheral wall 22b.
[0027] The folded portion W1 moves along the extending direction X, for example, with the sliding movement of the slide sheet. Specifically, when the folded portion W1 is inserted or removed from the opening 2 with the sliding movement of the slide sheet, it can move along the extending direction X between a first position P1 adjacent to the side of the step portion 26b and a second position P2 adjacent to the base side third peripheral wall 12c and the cover side third peripheral wall 22c. The wiring material W slides between the first position P1 and the second position P2 in the accommodation space 4 with the sliding movement of the slide sheet. For this reason, grease G (see FIG. 5) or the like is applied to the outer peripheral surface of the wiring material W sliding in the accommodation space 4 to facilitate smooth sliding.
[0028] The locking mechanism 30 has, for example, a locking portion 31 provided on the cover 20 side and a locked portion 32 provided on the base 10 side. The locking portion 31 is formed, for example, in a claw shape on the outer surface of the cover-side first peripheral wall 22a and the cover-side second peripheral wall 22b. Here, the cover-side first peripheral wall 22a and the cover-side second peripheral wall 22b are provided with a plurality of locking portions 31 spaced apart from each other in the extension direction X. The locking portion 31 protrudes from the cover-side first peripheral wall 22a and the cover-side second peripheral wall 22b in the vertical direction Z to the opposite side to the storage space portion 4, and has a locking surface 31a facing one side in the stacking direction Y. When the base 10 and the cover 20 are locked to each other, the locking surface 31a faces the locked portion 32 in the stacking direction Y.
[0029] The locked portion 32 is formed, for example, in a cylindrical shape having an opening on the outer surface of the base-side first peripheral wall 12a and the base-side second peripheral wall 12b along the stacking direction Y into which the locking portion 31 is inserted. Here, the locked portion 32 is provided at a position corresponding to the locking portion 31 on the base-side first peripheral wall 12a and the base-side second peripheral wall 12b, and the locking portion 31 is inserted and locked. The locked portion 32 has a locked surface 32a facing the other side in the stacking direction Y. The locked surface 32a faces the locking surface 31a in the stacking direction Y, and the locking surface 31a and the locked surface 32a are locked together, thereby restricting movement (detachment) of the base 10 to the other side in the stacking direction Y relative to the cover 20.
[0030] FIG. 4 is a perspective view of the vicinity of the curved surface portion 28 of the protector 1, showing a state before the tip portion 12a1 of the base side first peripheral wall 12a rides on the curved surface portion 28. As shown in FIG. 4, in this embodiment, an arc-shaped curved surface portion 28 is provided at an inner corner portion 27 between the cover side first peripheral wall 22a and the cover side bottom wall 21. The curved surface portion 28 is configured in a substantially U-shape that opens toward the wiring material W. Here, the inner corner portion 27 is provided with a plurality of curved surface portions 28 spaced apart from each other in the extension direction X. The plurality of curved surface portions 28 function as guides that guide the tip portion 12a1 of the base side first peripheral wall 12a toward the upper end portion 28b of the curved surface portion 28, for example, when the base 10 and the cover 20 are fitted and assembled.
[0031] Specifically, the curved surface portion 28 has, for example, an upper end portion 28b connected to the inner surface of the cover-side bottom wall 21, a lower end portion 28c (see FIG. 5) connected to the inner surface of the cover-side first peripheral wall 22a, and an arc surface 28a (R surface) extending between the upper end portion 28b and the lower end portion 28c. The upper end portion 28b is formed substantially flush with the inner surface of the cover-side bottom wall 21, and the lower end portion 28c is formed substantially flush with the inner surface of the cover-side first peripheral wall 22a. The arc surface 28a protrudes into the storage space 4 beyond the inner surfaces of the cover-side bottom wall 21 and the cover-side first peripheral wall 22a. Therefore, in this embodiment, by sliding the base 10 relative to the cover 20 along the stacking direction Y and engaging it, the tip portion 12a1 of the base side first peripheral wall 12a is guided along the arc surface 28a from the lower end portion 28c side of the curved shaped portion 28 toward the upper end portion 28b side.
[0032] The base-side first peripheral wall 12a has, for example, a tip end 12a1 located on one side (the cover 20 side) in the stacking direction Y, and a base end 12a2 located on the other side in the stacking direction Y and connected to the base-side bottom wall 11. In this embodiment, the first thickness T1 in the vertical direction Z at the tip end 12a1 of the base-side first peripheral wall 12a is configured to be thinner than a second thickness T2 (see FIG. 5) in the vertical direction Z at the base end 12a2 of the base-side first peripheral wall 12a. Specifically, the first thickness T1 at the tip end 12a1 of the base-side first peripheral wall 12a is configured to be thinner than a curved surface range T3 (see FIG. 5) in the vertical direction Z between the upper end 28b and the lower end 28c of the curved surface portion 28.
[0033] In this embodiment, in order to prevent leakage of the grease G applied inside the housing space 4 when the base 10 and the cover 20 are fitted together, the base 10 and the cover 20 need to be assembled in a state in which the tip portion 12a1 of the base-side first peripheral wall 12a is elastically deformed to improve adhesion between the tip portion 12a1 and the cover-side bottom wall 21. Therefore, if the first thickness T1 of the tip portion 12a1 of the base-side first peripheral wall 12a is configured to be substantially the same as the second thickness T2 of the base end portion 12a2, the fitting load between the base 10 and the cover 20 required for elastic deformation of the tip portion 12a1 increases, and there is a risk that the assemblability of the base 10 and the cover 20 may deteriorate.
[0034] In this regard, in the present embodiment, the first thickness T1 of the tip portion 12a1 of the base-side first peripheral wall 12a is configured to be thinner than the second thickness T2 of the base end portion 12a2, so that an increase in the fitting load between the base 10 and the cover 20 required for elastic deformation of the tip portion 12a1 can be suppressed, and deterioration of the assembling performance thereof can be suppressed. Also, in the present embodiment, when the base 10 and the cover 20 are assembled, the tip portion 12a1 of the base-side first peripheral wall 12a rides on the above-mentioned curved surface portion 28, so that the tip portion 12a1 and the cover-side bottom wall 21 are in close contact with each other.
[0035] 5 is a cross-sectional view of the vicinity of the curved surface portion 28 of the protector 1, showing a state after the tip portion 12a1 of the base side first peripheral wall 12a rides up on the curved surface portion 28. As shown in FIG. 5, in this embodiment, when the base 10 and the cover 20 are fitted and assembled, the rigidity (strength) of the tip portion 12a1 of the base side first peripheral wall 12a is lower than the rigidity (strength) of the base end portion 12a2, so that the tip portion 12a1 of the base side first peripheral wall 12a can bend along the curved surface portion 28. As a result, a recess 18 is formed between the tip portion 12a1 and the base end portion 12a2 of the base side first peripheral wall 12a. The recess 18 is a space portion in which grease G is stored that is recessed downward in the vertical direction Z and opened upward in the vertical direction Z, and extends along the extension direction X. In FIG. 5, for the sake of convenience, the curved portion at the tip end 12a1 of the base-side first circumferential wall 12a is exaggerated.
[0036] In this embodiment, the tip 12a1 of the base-side first peripheral wall 12a is curved upward in the vertical direction Z and toward the other side (base 10 side) in the stacking direction Y from the free state when the base 10 and the cover 20 are assembled. This generates an elastic restoring force at the tip 12a1 of the base-side first peripheral wall 12a, increasing the surface pressure between the tip 12a1 and the cover-side bottom wall 21 (upper end 28b of the curved surface portion 28), thereby improving the sealing performance at these positions. In this embodiment, the above-mentioned locking mechanism 30 locks the locking portion 31 and the locked portion 32 when an elastic restoring force is generated at the tip 12a1 of the base-side first peripheral wall 12a. When the locking portion 31 and the locked portion 32 are locked together, movement (disengagement) of the base 10 to the other side in the stacking direction Y relative to the cover 20 is restricted, and an increased surface pressure is maintained between the tip portion 12a1 of the base side first peripheral wall 12a and the cover side bottom wall 21.
[0037] In this embodiment, a case has been illustrated in which the tip portion 12a1 of the base-side first peripheral wall 12a is curved along the curved-shaped portion 28 and the tip portion 12a1 and the cover-side bottom wall 21 are in close contact with each other. However, this example is not limited to this, and for example, the tip portion 12a1 and the cover-side bottom wall 21 may be configured to be in close contact with each other in a state in which the tip portion 12a1 of the base-side first peripheral wall 12a simply rides up on the curved-shaped portion 28, that is, in a state in which the tip portion 12a1 of the base-side first peripheral wall 12a shown in Figure 4 is slid upward in the vertical direction Z relative to the curved-shaped portion 28 (a state in which the tip portion 12a1 and the cover-side bottom wall 21 are not curved along the curved-shaped portion 28).
[0038] As described above, in the protector 1 and wire harness WH of this embodiment, the first thickness T1 along the vertical direction Z at the tip portion 12a1 of the base side first peripheral wall 12a is configured to be thinner than the second thickness T2 along the vertical direction Z at the base end portion 12a2 of the base side first peripheral wall 12a, and the base 10 and the cover 20 are assembled with the tip portion 12a1 of the base side first peripheral wall 12a riding on the curved shaped portion 28 and in close contact with the cover side bottom wall 21. With this configuration, when assembling the base 10 and the cover 20, the protector 1 and the wire harness WH can be assembled to the base 10 by relatively easily deforming the tip portion 12a1, which is thinner than the base end portion 12a2 of the base-side first peripheral wall 12a, and thus the adhesion between the tip portion 12a1 of the base-side first peripheral wall 12a and the cover-side bottom wall 21 can be improved to close the gap between the tip portion 12a1 and the cover-side bottom wall 21. As a result, the protector 1 and the wire harness WH can suppress leakage of the grease G applied inside the housing space 4.
[0039] In the protector 1 and wire harness WH of this embodiment, when the base 10 and the cover 20 are assembled, the tip end 12a1 of the base-side first peripheral wall 12a is curved along the curved surface portion 28, and a recess 18 is formed between the tip end 12a1 and the base end 12a2 of the base-side first peripheral wall 12a. With this configuration, in the protector 1 and the wire harness WH, for example, the recess 18 forms a space (grease reservoir) in which the grease G applied inside the housing space 4 is stored, and this further prevents the grease G from leaking.
[0040] In the protector 1 and wire harness WH of this embodiment, the first thickness T1 at the tip portion 12a1 of the base-side first peripheral wall 12a is configured to be thinner than the curved range T3 along the vertical direction Z between the upper end portion 28b and the lower end portion 28c of the curved portion 28. This configuration allows the protector 1 and wire harness WH to, for example, allow the tip portion 12a1 of the base-side first peripheral wall 12a to ride up the curved portion 28 more easily, or allow the tip portion 12a1 of the base-side first peripheral wall 12a to deform along the curved portion 28 more easily.
[0041] In the protector 1 and wire harness WH of this embodiment, the inner corner 27 is provided with a plurality of curved surface portions 28 spaced apart from one another in the extension direction X intersecting with the stacking direction Y and the vertical direction Z. With this configuration, the protector 1 and wire harness WH can make the cover 20 lighter and can suppress wear between the cover 20 and the base 10, for example, compared to a case in which the curved surface portions 28 are provided continuously between one end and the other end of the inner corner 27 in the extension direction X.
[0042] In the present embodiment, a case has been illustrated in which a plurality of curved surface portions 28 are intermittently provided along the extension direction X at the inner corner portion 27 between the cover side first peripheral wall 22a and the cover side bottom wall 21. However, this example is not limited to this. For example, the curved surface portions 28 may be continuously provided between one end and the other end of the inner corner portion 27 in the extension direction X.
[0043] Although the embodiment of the present invention has been illustrated above, the above embodiment is merely an example and is not intended to limit the scope of the invention. The above embodiment can be implemented in various other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the gist of the invention. In addition, the specifications of each configuration, shape, and the like (structure, type, direction, format, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be appropriately changed and implemented.
