Description

Technical Field

[0001] This invention relates to a shape maintaining structure of a member to be attached, which is composed of, for example, a protector that covers and protects a wire harness or an electric wire, and an attaching member that is attached to the member to be attached, and an attaching member.

Background Art

[0002] In a vehicle such as an automobile, as a protector that covers and protects an electric wire or a wire harness, or regulates a route, for example, as in Patent Document 1, a plate material is bent to form a rectangular cylindrical body extending in a predetermined direction, and an electric wire or a wire harness is inserted into its internal space.

[0003] Specifically, the protector of Patent Document 1 is composed of a resin plate material, and is bent along the fold line so that the plate materials overlap each other on all surfaces to form a rectangular cylindrical shape. Further, the protector of Patent Document 1 constitutes a rectangular cylindrical body having a substantially annular cross section by connecting the overlapped portions of the bent plate materials with a locking component.

[0004] By the way, since the protector of Patent Document 1 overlaps the plate materials so that each surface of the quadrangular prism is doubled, and further connects the plate materials with a locking component, its weight tends to be heavy. In such a protector whose weight tends to be heavy, there is a risk that an unintended load may act on a wire harness or the like.

[0005] Therefore, for example, by bending the plate material into a substantially U shape to form a protector having an open cross-sectional shape with one side in the orthogonal direction open, it is conceivable to reduce the weight of the protector. However, since the protector is likely to be deformed in the orthogonal direction, there is a problem that the desired cross-sectional shape of the protector cannot be maintained.

SUMMARY OF THE INVENTION

PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] In view of the above problems, an object of the present invention is to provide a shape maintenance structure for a mounted member that can maintain a desired cross-sectional shape of the mounted member even if the mounted member has an open cross-sectional shape, and a mounting member.

MEANS FOR SOLVING THE PROBLEMS

[0008] This invention is composed of a mounted member having an open cross-sectional shape extending in a predetermined direction formed by bending or curving a plate material, and a mounting member mounted on the mounted member to maintain the cross-sectional shape of the mounted member. The mounting member includes a main body portion having a plurality of contact surfaces with which the mounted member abuts from an orthogonal direction orthogonal to the predetermined direction, and a restricting portion that restricts the mounted member in contact with the contact surface from separating from the contact surface in the orthogonal direction. Further, in a cross-section along the orthogonal direction, the mounting member includes a main body portion formed in an open cross-sectional shape having the contact surface on its inner surface and an opening through which the member to be mounted can be inserted and removed, and a lid portion that covers the opening of the main body portion by contacting the member to be mounted and is locked to the main body portion. The restricting portion is formed by the lid portion It is characterized by being a shape maintenance structure of the mounted member.

[0009] The mounted member having the above open cross-sectional shape refers to, for example, a mounted member having a substantially U-shaped cross-section extending in a predetermined direction, a mounted member having a substantially L-shaped cross-section, and the like. The mounted member abutting from the above orthogonal direction means that the mounted member abuts from the inner side in the orthogonal direction or the mounted member abuts from the outer side in the orthogonal direction.

[0010] The mounted member in contact with the contact surface separating from the contact surface in the orthogonal direction means, for example, that the mounted member separates so as to tilt in the orthogonal direction or the mounted member separates so as to move in the orthogonal direction.

[0011] According to the present invention, the shape maintaining structure of the member to be attached can maintain the state where the member to be attached is in contact with the contact surface of the attaching member by the restricting portion of the attaching member. Therefore, the shape maintaining structure of the member to be attached can maintain the desired cross-sectional shape of the member to be attached even if the member to be attached has an open cross-sectional shape.

[0012] Also, in a cross-section along the orthogonal direction, the mounting member includes a main body portion formed in an open cross-sectional shape having the contact surface on its inner surface and an opening through which the member to be mounted can be inserted and removed, and a lid portion that covers the opening of the main body portion by contacting the member to be mounted and is locked to the main body portion. The restricting portion is formed by the lid portion.

[0013] According to this configuration, the mounting member can prevent, for example, the member to be mounted from separating from the contact surface so as to detach from the main body portion through the opening of the main body portion, by means of the lid portion. Thereby, the shape maintaining structure of the member to be mounted can stably maintain the state in which the member to be mounted is in contact with the contact surface of the mounting member. For this reason, the shape maintaining structure of the member to be mounted can surely maintain the desired cross-sectional shape of the member to be mounted.

[0014] Furthermore, for example, when the movement of the member to be mounted in a predetermined direction is not restricted, the shape maintaining structure of the member to be mounted can place the mounting member at a desired position in the predetermined direction while maintaining the desired cross-sectional shape of the member to be mounted.

[0015] As an aspect of the present invention, the restricting portion may be constituted by a wall portion that sandwiches the member to be attached with the contact surface. According to this configuration, the attaching member can, for example, prevent the member to be attached from separating from the contact surface so as to tilt in the orthogonal direction by the wall portion.

[0016] Therefore, the shape maintaining structure of the member to be attached can maintain the state where the member to be attached is in contact with the contact surface of the attaching member. Thereby, the shape maintaining structure of the member to be attached can surely maintain the desired cross-sectional shape of the member to be attached.

[0017] Furthermore, for example, when the movement of the member to be attached in a predetermined direction is not restricted, the shape maintaining structure of the member to be attached can arrange the attaching member at a position in the desired predetermined direction while maintaining the desired cross-sectional shape of the member to be attached.

[0018] Also, as an aspect of the present invention, the restricting portion may be constituted by a locking portion that is locked to the member to be attached that is in contact with the contact surface. According to this configuration, the attaching member can, for example, prevent the member to be attached from separating from the contact surface so as to tilt in the orthogonal direction by the locking portion.

[0019] Therefore, the shape maintenance structure of the mounted member can maintain the state in which the mounted member is in contact with the contact surface of the mounting member. Thereby, the shape maintenance structure of the mounted member can reliably maintain the desired cross-sectional shape of the mounted member.

[0020] As another aspect of the present invention, the main body portion of the mounting member is inserted into the insertion hole provided in the mounted member, and has a melt that melts at a predetermined temperature on the contact surface, and the locking portion may be formed by melting the tip of the melt inserted into the insertion hole. The above-mentioned melt may be integrated with the main body portion or may be a separate body from the main body portion.

[0021] According to this configuration, the shape maintenance structure of the mounted member can not only restrict the mounted member from separating from the contact surface in the orthogonal direction, but also restrict the movement of the mounted member in a predetermined direction by the locking portion.

[0022] Thereby, the shape maintenance structure of the mounted member can stably maintain the state in which the mounted member is in contact with the contact surface of the mounting member. Therefore, the shape maintenance structure of the mounted member can reliably maintain the desired cross-sectional shape of the mounted member.

[0023] As another aspect of the present invention, the restricting portion may be configured to fit into a fitting portion provided in the mounted member. Fitting into the above-mentioned fitting portion means that the restricting portion fits into the fitting portion without a gap, or the restricting portion loosely fits into the fitting portion. According to this configuration, the shape maintenance structure of the mounted member can not only restrict the mounted member from separating from the contact surface in the orthogonal direction, but also suppress the movement of the mounted member in at least a predetermined direction.

[0024] As another aspect of the present invention, the restricting portion may be provided opposite to the orthogonal direction orthogonal to the predetermined direction. According to this configuration, the shape maintenance structure of the member to be worn can stably maintain the desired cross-sectional shape of the member to be worn by the restricting portion of the wearing member.

[0025] As another aspect of the present invention, the restricting portions may be arranged in a staggered pattern along the predetermined direction. According to this configuration, the shape maintenance structure of the member to be worn can stably maintain the desired cross-sectional shape of the member to be worn while suppressing an increase in the weight of the wearing member even for a member to be worn that is long in the predetermined direction.

[0026] As another aspect of the present invention, the member to be worn may be provided with a curved portion, and the main body portion of the wearing member may be formed in a shape along the curved portion of the member to be worn. According to this configuration, the shape maintenance structure of the member to be worn can maintain the desired cross-sectional shape of the member to be worn and reinforce the curved portion of the member to be worn.

[0027] Therefore, for example, in the case of a member to be worn that protects a wire harness, the shape maintenance structure of the member to be worn can prevent the member to be worn from deforming due to the reaction force of the curved wire harness.

[0028] As another aspect of the present invention, the wearing member may be provided with an attachment portion for attaching to another member. The attachment portion refers to, for example, a clip or a seating surface for bolt fastening. According to this configuration, the shape maintenance structure of the member to be worn can easily attach the member to be worn with the desired shape maintained to another member.

[0029] The present invention also provides a main body portion having a plurality of abutting surfaces that abut against a member to be worn having an open cross-sectional shape extending in a predetermined direction formed by bending or curving a plate material from an orthogonal direction orthogonal to the predetermined direction, and a restricting portion that restricts the member to be worn abutting against the abutting surface from separating from the abutting surface in the orthogonal direction. In a cross-section along the orthogonal direction, the mounting member includes a main body portion formed in an open cross-sectional shape having the contact surface on its inner surface and an opening through which the member to be mounted can be inserted and removed, and a lid portion that covers the opening of the main body portion by contacting the member to be mounted and is locked to the main body portion. The restricting portion is formed by the lid portion, It is characterized by being a mounting member that is mounted on the mounted member and maintains the cross-sectional shape of the mounted member. According to the present invention, the mounting member can maintain the desired cross-sectional shape of the mounted member even if the mounted member has an open cross-sectional shape.

Effect of the Invention

[0030] The present invention can provide a shape maintenance structure for a mounted member and a mounting member that can maintain the desired cross-sectional shape of the mounted member even if the mounted member has an open cross-sectional shape.

Embodiments for Carrying out the Invention

[0032] An embodiment of this invention will be described below with reference to the drawings.

Examples

[0033] Example 1 relates to a shape maintenance structure of a member to be worn, which is composed of a protector 1 (member to be worn) having an open cross-sectional shape for covering and protecting a wire harness WH, and a mounting member 2 mounted on the protector 1 for maintaining the cross-sectional shape of the protector 1. This will be described with reference to FIGS. 1 to 3.

[0034] Note that FIG. 1 shows an external perspective view of the shape maintenance structure of the member to be worn in Example 1, FIG. 2 is an exploded perspective view showing the exteriors of the protector 1 and the mounting member 2, FIG. 2(a) shows an exploded perspective view in an obliquely upward view, and FIG. 2(b) shows an exploded perspective view in an obliquely downward view.

[0035] Furthermore, FIG. 3 is an explanatory diagram for explaining the protector 1 and the mounting member 2 in terms of cross-sectional shape. FIG. 3(a) shows a plan view of the protector 1 and the mounting member 2, and FIG. 3(b) shows a cross-sectional view taken along the arrow A - A in FIG. 3(a).

[0036] Also, the arrow X in the figure indicates the longitudinal direction of the protector 1 (hereinafter referred to as the longitudinal direction X), and the arrow Y indicates the direction orthogonal to the longitudinal direction X in a plan view (hereinafter referred to as the width direction Y). Further, in the width direction Y, the direction from one protector side portion 12 to be described later toward the other protector side portion 12 is defined as the inner side of the width direction Y, and the direction opposite to the inner side of the width direction Y is defined as the outer side of the width direction Y. In addition, the upper side in FIG. 1 is defined as the upper direction, and the lower side in FIG. 1 is defined as the lower direction.

[0037] As shown in FIG. 1, the protector 1 for protecting the wire harness WH is formed of a thermoplastic resin foam sheet and has a substantially U-shaped groove shape with an open upper surface portion in a square tube shape. The internal space of this protector 1 is formed as a space for accommodating the wire harness WH shown by the two-dot chain line in FIG. 1.

[0038] Specifically, as shown in FIGS. 1 to 3, the protector 1 is formed by mountain-folding a flat thermoplastic resin foam sheet that is long in a predetermined direction along a fold line extending in the predetermined direction, and has a substantially U-shaped cross section with corners and extending in the predetermined direction. In other words, the protector 1 is formed in a substantially U-shaped groove shape with the predetermined direction as the longitudinal direction.

[0039] Here, the thermoplastic resin foam sheet constituting the protector 1 will be described in detail. The density of the thermoplastic resin foam sheet is not particularly limited. For example, from the point of preventing anisotropy of mechanical properties, that is, equalizing mechanical properties, improving the degree of freedom in the design of the protector 1, and further improving the strength against stress on the wire harness WH accommodated in the protector 1, 200 Kg / m 3 to 1000 Kg / m 3 is preferable, and from the point of further improving the balance between light weight and mechanical strength, 300 Kg / m 3 to 600 Kg / m 3 is more preferable, and 350 Kg / m 3 to 550 Kg / m 3 is particularly preferable.

[0040] The thickness of the thermoplastic resin foam sheet constituting the protector 1 is not particularly limited. For example, from the viewpoint of improving the balance between ease of bending and mechanical strength, particularly the mechanical strength against stress applied to the wire harness WH housed in the protector 1, it is preferably 0.50 mm or more and 4.0 mm or less, and particularly preferably 1.0 mm or more and 2.5 mm or less.

[0041] Further, a non-foamed layer may be formed on both sides or one side of the thermoplastic resin foam sheet. That is, the thermoplastic resin foam sheet may have a structure having a foamed layer and a non-foamed layer formed on the foamed layer. By forming a non-foamed layer on the surface of the thermoplastic resin foam sheet, the mechanical strength of the protector 1 is improved, and the protection performance of the housed wire harness WH is further improved. The thickness of the non-foamed layer is not particularly limited, and examples thereof include 10 μm or more and 100 μm or less.

[0042] Further, the number density of bubbles in the foamed layer of the thermoplastic resin foam sheet constituting the protector 1 is not particularly limited. The lower limit value thereof is preferably 800 bubbles / mm 3 or more, and particularly preferably 1000 bubbles / mm 3 or more, from the viewpoint of more reliably preventing anisotropy of mechanical properties. On the other hand, the upper limit value of the above-mentioned number density of bubbles is, for example, 1010 bubbles / mm 3 or less, from the viewpoint of more reliably obtaining excellent mechanical strength.

[0043] As shown in FIGS. 1 to 3, the protector 1 formed of such a thermoplastic resin foam sheet is formed in a groove shape having a substantially U-shaped cross section extending in the longitudinal direction X by a flat protector bottom 11 and a pair of protector side portions 12.

[0044] Specifically, as shown in FIGS. 2 and 3, the protector bottom 11 is formed in a substantially flat plate shape with the vertical direction as the thickness. The lower surface of the protector bottom 11 is formed as a contact surface 11a that contacts the mounting member 2 described later, as shown in FIG. 3(b).

[0045] Furthermore, as shown in FIGS. 2 and 3, at the bottom 11 of the protector, a pair of first insertion holes 13 provided at both ends in the width direction Y and one second insertion hole 14 provided substantially at the center in the width direction Y between the first insertion holes 13 are formed to penetrate in the vertical direction.

[0046] Specifically, the pair of first insertion holes 13 are openings that are substantially rectangular in plan view and long in the longitudinal direction X, and are formed such that a regulating portion (wall portion 23) of the mounting member 2 described later can be inserted therethrough. On the other hand, the second insertion hole 14 is an opening that is substantially rectangular in plan view and is formed at a position substantially in the same longitudinal direction X as the center in the longitudinal direction X of the first insertion hole 13. This second insertion hole 14 is formed such that a regulating portion (locking portion 24) of the mounting member 2 described later can be fitted therein.

[0047] As shown in FIGS. 2 and 3, the side portion 12 of the protector is substantially flat plate-shaped with the width direction Y as the thickness, and is formed to stand up upward from both ends in the width direction Y of the bottom 11 of the protector. Note that, as shown in FIG. 3(b), the side portion 12 of the protector is formed as a contact surface 12a on which a surface in the width direction Y (the main surface on the outer side in the width direction Y) continuous with the lower surface of the bottom 11 of the protector contacts the mounting member 2 described later.

[0048] The mounting member 2 that maintains the cross-sectional shape of the protector 1 is made of a thermoplastic resin such as polypropylene, and is formed in a substantially U-shaped groove shape having a space capable of accommodating the protector 1 as shown in FIGS. 1 and 2.

[0049] This mounting member 2 includes a main body portion 21 having a plurality of contact surfaces (bottom contact surface 211a and side contact surface 212a described later) with which the protector 1 contacts from the width direction Y and the vertical direction, and a clip portion 22 for attaching to another member (not shown).

[0050] Furthermore, the mounting member 2 includes a pair of wall portions 23 as a regulating portion that regulates the protector 1 contacting the side contact surface 212a described later from separating from the side contact surface 212a toward the inner side in the width direction Y. In addition, the mounting member 2 includes one locking portion 24 as a restricting portion that restricts the protector 1 in contact with the bottom contact surface 211a described later from moving upward and separating from the bottom contact surface 211a.

[0051] Specifically, as shown in FIGS. 1 and 2, the main body portion 21 of the mounting member 2 is formed in a groove shape extending in the longitudinal direction X with a substantially U-shaped cross-sectional shape having corners. As shown in FIGS. 2 and 3, this main body portion 21 is integrally formed by a bottom surface portion 211 with which the protector bottom portion 11 comes into contact in the vertical direction and a pair of side surface portions 212 with which the protector side portions 12 come into contact in the width direction Y.

[0052] As shown in FIGS. 2 and 3, the bottom surface portion 211 of the main body portion 21 is formed in a substantially flat plate shape with the vertical direction as the thickness. The upper surface of this bottom surface portion 211 is formed as a bottom contact surface 211a with which the contact surface 11a of the protector bottom portion 11 comes into contact, as shown in FIG. 3(b). Furthermore, as shown in FIGS. 2 and 3, a clip portion 22 is provided downward on the lower surface of the bottom surface portion 211.

[0053] As shown in FIGS. 2 and 3, the pair of side surface portions 212 of the main body portion 21 stand up upward from the bottom contact surface 211a of the bottom surface portion 211 with substantially the same interval in the width direction Y as the interval between the contact surfaces 12a of the protector side portions 12.

[0054] As shown in FIG. 3, this side surface portion 212 is substantially flat plate-shaped with the width direction Y as the thickness, and its upper end surface is formed to have a vertical length that is substantially flush with the upper end of the protector 1 housed in the main body portion 21.

[0055] Note that, as shown in FIG. 3(b), the side surface portion 212 is formed with a surface in the width direction Y (the main surface on the inner side in the width direction Y) continuous with the upper surface of the bottom surface portion 211 as a side contact surface 212a with which the contact surface 12a of the protector side portion 12 comes into contact.

[0056] In addition, as shown in FIGS. 1 to 3, a pair of wall portions 23, which are restricting portions, are erected opposite to the side surface portion 212 on the inner side in the width direction Y with respect to the side surface portion 212 so as to sandwich the protector 1 with the side surface portion 212 of the main body portion 21.

[0057] Specifically, as shown in FIG. 3, the wall portion 23 is erected upward from the bottom contact surface 211a of the bottom surface portion 211 with a space in the width direction Y substantially the same as the thickness of the protector side portion 12. The wall portion 23 has a substantially flat plate shape with the width direction Y as its thickness, and the length in the longitudinal direction X and the length in the vertical direction are formed to be substantially the same as the length of the side surface portion 212.

[0058] In addition, a locking portion 24, which is a restricting portion, is locked to the protector bottom portion 11 and is erected upward from the bottom contact surface 211a of the bottom surface portion 211 so as to sandwich the protector bottom portion 11 with the bottom surface portion 211 of the main body portion 21, as shown in FIGS. 1 and 3. As shown in FIG. 3, this locking portion 24 is formed substantially at the center of the bottom surface portion 211 in the longitudinal direction X and the width direction Y.

[0059] Specifically, the locking portion 24 is composed of a melt 25 such as a thermoplastic resin material that melts at a predetermined temperature, and is formed by melting the tip of the melt 25 in a state where it is inserted into the second insertion hole 14 of the protector 1. As shown in FIG. 2, the melt 25 has a substantially columnar shape erected upward from the bottom contact surface 211a of the bottom surface portion 211, and is formed to have a length in the vertical direction longer than the thickness of the protector bottom portion 11.

[0060] More specifically, as shown in FIG. 3(b), the locking portion 24 is composed of a fitting portion 24a that fits into the second insertion hole 14 of the protector bottom portion 11 and a shaping portion 24b formed by melting and shaping the tip of the melt 25 exposed above the protector bottom portion 11.

[0061] The fitting portion 24a is substantially rectangular in plan view with substantially the same size as the second insertion hole 14 of the protector bottom portion 11, and is formed in a substantially columnar shape that stands upright upward from the bottom contact surface 211a of the bottom surface portion 211.

[0062] On the other hand, the shaping portion 24b is substantially flat plate-shaped with the vertical direction as the thickness, and is formed in a substantially rectangular shape in plan view that is larger than the fitting portion 24a. This shaping portion 24b is formed to contact the upper surface of the protector bottom portion 11 and sandwich the protector bottom portion 11 with the bottom surface portion 211 of the main body portion 21.

[0063] Next, an assembling process for assembling the mounting member 2 to the protector 1 having the above-described configuration will be described with reference to FIG. 4. Note that FIG. 4 is an explanatory diagram for explaining the outline of the assembling process. FIG. 4(a) shows a cross-sectional view for explaining the assembling direction in the A-A arrow view, and FIG. 4(b) shows a cross-sectional view for explaining the process of forming the shaping portion 24b of the locking portion 24.

[0064] First, as shown in FIG. 4(a), the operator assembles the mounting member 2 to the protector 1 from below. At this time, the operator inserts the melt 25 of the mounting member 2 into the second insertion hole 14 of the protector 1 and assembles it while inserting the wall portion 23 of the mounting member 2 into the first insertion hole 13 of the protector 1. For this reason, the protector side portion 12 is guided between the side surface portion 212 and the wall portion 23 of the mounting member 2, and the contact surface 12a contacts the side contact surface 212a of the mounting member 2.

[0065] Then, when the bottom contact surface 211a of the mounting member 2 contacts the contact surface 11a of the protector bottom portion 11, the operator melts and shapes the tip of the melt 25 exposed from the protector bottom portion 11 with a predetermined melting device as shown in FIG. 4(b) to form the shaping portion 24b of the locking portion 24. As a result, the protector side portion 12 is sandwiched between the side surface portion 212 and the wall portion 23 of the mounting member 2, and the protector bottom portion 11 is locked to the bottom surface portion 211 of the mounting member 2.

[0066] In this way, in the shape maintaining structure of the member to be worn, the pair of wall portions 23 regulate the inclination of the protector 1 in contact with the side contact surface 212a toward the inside in the width direction Y with the lower end as a fulcrum, and the locking portion 24 regulates the separation of the protector 1 in contact with the bottom contact surface 211a upward from the bottom contact surface 211a. Further, the shape maintaining structure of the member to be worn restricts the movement of the protector 1 in the longitudinal direction X by the second insertion hole 14 of the protector 1 and the locking portion 24 of the mounting member 2.

[0067] As described above, the shape maintaining structure of the member to be worn in the first embodiment is composed of a protector 1 having an open cross-sectional shape extending in the longitudinal direction X formed by bending a thermoplastic resin foam sheet, and a mounting member 2 mounted on the protector 1 to maintain the cross-sectional shape of the protector 1. Furthermore, the mounting member 2 is provided with a main body portion 21 having a bottom contact surface 211a against which the protector 1 abuts from above and below, and a side contact surface 212a against which the protector 1 abuts from the width direction Y.

[0068] Furthermore, the mounting member 2 is provided with a regulating portion (locking portion 24) that regulates the separation of the protector 1 in contact with the bottom contact surface 211a upward from the bottom contact surface 211a. In addition, the mounting member 2 is provided with a regulating portion (wall portion 23) that regulates the separation of the protector 1 in contact with the side contact surface 212a from the side contact surface 212a in the width direction Y.

[0069] According to this, the shape maintaining structure of the member to be worn can maintain the state in which the protector 1 is in contact with the contact surface of the mounting member 2 by the regulating portion of the mounting member 2. For this reason, the shape maintaining structure of the member to be worn can maintain the desired cross-sectional shape of the protector 1 even if the protector 1 has an open cross-sectional shape.

[0070] The regulating portion is composed of a wall portion 23 that sandwiches the protector 1 with the side contact surface 212a. According to this configuration, the mounting member 2 can be prevented by the wall portion 23 from separating from the side contact surface 212a so that the protector 1 tilts in the width direction Y.

[0071] Therefore, the shape maintaining structure of the member to be mounted can maintain the state in which the protector 1 is in contact with the side contact surface 212a of the mounting member 2. As a result, the shape maintaining structure of the member to be mounted can surely maintain the desired cross-sectional shape of the protector 1.

[0072] Further, the restricting portion is constituted by a locking portion 24 that is locked to the protector 1 in contact with the bottom contact surface 211a. According to this configuration, the mounting member 2 can be prevented by the locking portion 24 from separating from the bottom contact surface 211a with the protector 1 directed upward.

[0073] Therefore, the shape maintaining structure of the member to be mounted can maintain the state in which the protector 1 is in contact with the bottom contact surface 211a of the mounting member 2. As a result, the shape maintaining structure of the member to be mounted can surely maintain the desired cross-sectional shape of the protector 1.

[0074] Further, the main body portion 21 of the mounting member 2 is inserted into the second insertion hole 14 provided in the protector 1 and has a melt 25 that melts at a predetermined temperature on the bottom contact surface 211a. The locking portion 24 is formed by melting the tip of the melt 25 inserted into the second insertion hole 14.

[0075] According to this configuration, the shape maintaining structure of the member to be mounted not only restricts the protector 1 from separating from the bottom contact surface 211a upward, but also can restrict the movement of the protector 1 in the longitudinal direction X by the locking portion 24.

[0076] As a result, the shape maintaining structure of the member to be mounted can stably maintain the state in which the protector 1 is in contact with the bottom contact surface 211a of the mounting member 2. Therefore, the shape maintaining structure of the member to be mounted can surely maintain the desired cross-sectional shape of the protector 1.

[0077] Further, the wall portion 23 is provided so as to face the width direction Y orthogonal to the longitudinal direction X. According to this configuration, the shape maintaining structure of the member to be attached can stably maintain the desired cross-sectional shape of the protector 1 by the wall portion 23 of the attachment member 2.

[0078] Further, the attachment member 2 is provided with a clip portion 22 for attaching to another member. According to this configuration, the shape maintaining structure of the member to be attached can easily attach the protector 1 having the desired shape maintained to another member.

[0079] Further, the attachment member 2 is provided with a main body portion 21 having a bottom contact surface 211a with which the protector 1 formed by bending a thermoplastic resin foam sheet and extending in the longitudinal direction X abuts from above and below, and a side contact surface 212a with which the protector 1 abuts from the width direction Y.

[0080] Furthermore, the attachment member 2 is provided with a regulating portion (locking portion 24) that regulates the protector 1 in contact with the bottom contact surface 211a from separating upward from the bottom contact surface 211a.

[0081] In addition, the attachment member 2 is provided with a regulating portion (wall portion 23) that regulates the protector 1 in contact with the side contact surface 212a from separating from the side contact surface 212a in the width direction Y, and maintains the cross-sectional shape of the protector 1 when attached to the protector 1.

[0082] According to this, the attachment member 2 can maintain the desired cross-sectional shape of the protector 1 even if the protector 1 has an open cross-sectional shape.

Example

[0083] For the above-described Example 1, a different Example 2 in which a regulating portion that restricts the protector 1 in contact with the side contact surface 212a from separating from the side contact surface 212a inward in the width direction Y will be described with reference to FIGS. 5 to 8.

[0084] Note that FIG. 5 shows an external perspective view of the shape-maintaining structure of the member to be attached in Example 2, FIG. 6 is an exploded perspective view showing the appearance of the protector 1 and the attachment member 2, FIG. 6(a) shows an exploded perspective view in an obliquely upward view, and FIG. 6(b) shows an exploded perspective view in an obliquely downward view.

[0085] Furthermore, FIG. 7 is an explanatory view for explaining the cross-sectional shapes of the protector 1 and the attachment member 2, FIG. 7(a) shows a plan view of the protector 1 and the attachment member 2, and FIG. 7(b) shows a cross-sectional view taken along the line B-B in FIG. 7(a). In addition, the same components as those in the above-described Example 1 are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

[0086] As shown in FIG. 5, the protector 1 of Example 2 is composed of a protector bottom portion 11 and a pair of protector side portions 12. Note that the first insertion hole 13 of Example 1 described above is not provided in the protector bottom portion 11 of the protector 1.

[0087] As shown in FIGS. 5 and 6, the attachment member 2 of Example 2 includes a main body portion 21 composed of a bottom surface portion 211 and a pair of side surface portions 212, a clip portion 22, and a regulating portion different from that of Example 1. More specifically, as shown in FIGS. 6 and 7, the attachment member 2 includes the same locking portion 24 as that of Example 1 above as a regulating portion that restricts the protector 1 in contact with the bottom contact surface 211a from separating from the bottom contact surface 211a upward.

[0088] Furthermore, as shown in FIGS. 6 and 7, the attachment member 2 includes a pair of holding portions 26 as a regulating portion that restricts the protector 1 in contact with the side contact surface 212a from separating from the side contact surface 212a inward in the width direction Y.

[0089] As shown in FIGS. 6 and 7(a), the holding portion 26 is formed at the upper end of the side surface portion 212 of the main body portion 21 with substantially the same length in the longitudinal direction X. Specifically, as shown in FIG. 7(b), the holding portion 26 is formed by an extending portion 26a extending inward in the width direction Y from the upper end of the side surface portion 212, and a claw portion 26b vertically provided downward from the tip of the extending portion 26a.

[0090] As shown in FIG. 7(b), the extending portion 26a extends with substantially the same length in the width direction Y as the thickness of the protector side portion 12. On the other hand, as shown in FIG. 7(b), the claw portion 26b is vertically provided with a vertical length facing the side surface portion 212 across the protector side portion 12 so as to sandwich the protector side portion 12 with the side surface portion 212 of the main body portion 21. Note that the lower part of the surface of the claw portion 26b facing the other holding portion 26 is chamfered.

[0091] Next, with reference to FIG. 8, which is an explanatory diagram for explaining the outline of the assembling process of assembling the mounting member 2 to the protector 1 having the above-described configuration, the assembling process will be described. First, as shown in FIG. 8, the operator preliminarily deforms the protector 1 so that the protector side portion 12 is tilted toward the protector bottom portion 11 with the lower end of the protector side portion 12 as a fulcrum.

[0092] Next, the operator assembles the mounting member 2 to the protector 1 from below, and brings the bottom contact surface 211a of the mounting member 2 into contact with the contact surface 11a of the protector bottom portion 11. Then, while standing the protector side portion 12 toward the side surface portion 212 of the mounting member 2, the operator locks the protector side portion 12 to the holding portion 26 of the mounting member 2 and brings the contact surface 12a of the protector side portion 12 into contact with the side contact surface 212a of the mounting member 2.

[0093] Furthermore, the operator melts and shapes the tip of the melt 25 exposed from the protector bottom portion 11 with a predetermined melting device to form the shaped portion 24b of the locking portion 24. As a result, the side portion 12 of the protector is held by the holding portion 26 of the mounting member 2, and the bottom portion 11 of the protector is locked to the bottom surface portion 211 of the mounting member 2.

[0094] In this way, the shape maintaining structure of the member to be mounted restricts the protector 1 in contact with the side contact surface 212a from tilting inward in the width direction Y with the lower end as a fulcrum by the pair of holding portions 26, and restricts the protector 1 in contact with the bottom contact surface 211a from moving upward and separating from the bottom contact surface 211a by the locking portion 24. Further, the shape maintaining structure of the member to be mounted restricts the movement of the protector 1 in the longitudinal direction X by the second insertion hole 14 of the protector 1 and the locking portion 24 of the mounting member 2.

[0095] As described above, the shape maintaining structure of the member to be mounted in the second embodiment includes a restricting portion (locking portion 24) that restricts the mounting member 2 from allowing the protector 1 in contact with the bottom contact surface 211a to move upward and separate from the bottom contact surface 211a. Furthermore, the shape maintaining structure of the member to be mounted includes a restricting portion (holding portion 26) that restricts the mounting member 2 from allowing the protector 1 in contact with the side contact surface 212a to move inward in the width direction Y and separate from the side contact surface 212a.

[0096] As a result, the shape maintaining structure of the member to be mounted can achieve the same effects as those of the first embodiment described above. Further, since the restricting portion is constituted by the holding portion 26, the mounting member 2 can prevent the protector 1 from separating from the side contact surface 212a inward in the width direction Y by the holding portion 26.

[0097] Therefore, the shape maintaining structure of the member to be mounted can maintain the state where the protector 1 is in contact with the side contact surface 212a of the mounting member 2. As a result, the shape maintaining structure of the member to be mounted can surely maintain the desired cross-sectional shape of the protector 1.

[0098] In addition, the holding portions 26 are provided to face each other in the width direction Y orthogonal to the longitudinal direction X. According to this configuration, the shape maintenance structure of the member to be worn can stably maintain the desired cross-sectional shape of the protector 1 by the holding portion 26 of the wearing member 2.

Embodiment

[0099] For a third embodiment different in that a restricting portion that restricts the protector 1 in contact with the side contact surface 212a from separating from the side contact surface 212a inward in the width direction Y is different from the above-described first embodiment, it will be described with reference to FIGS. 9 to 11.

[0100] Note that FIG. 9 shows an external perspective view of the shape maintenance structure of the member to be worn in the third embodiment, and FIG. 10 shows an exploded perspective view of the external appearance of the protector 1 and the wearing member 2. Furthermore, FIG. 11 is an explanatory view for explaining the protector 1 and the wearing member 2 in a cross-sectional shape. FIG. 11(a) shows a plan view of the protector 1 and the wearing member 2, and FIG. 11(b) shows a cross-sectional view taken along the line C-C in FIG. 11(a). In addition, the same configurations as those in the above-described first embodiment are denoted by the same reference numerals, and the detailed description thereof is omitted.

[0101] The protector 1 of the third embodiment is composed of a protector bottom portion 11 and a pair of protector side portions 12 as shown in FIGS. 9 and 10. Note that the first insertion hole 13 and the second insertion hole 14 of the first embodiment described above are not provided in the protector bottom portion 11 of the protector 1. Furthermore, as shown in FIG. 10, a notch portion 15 into which the wearing member 2 is fitted is formed in the protector side portion 12 by cutting off the upper end.

[0102] As shown in FIGS. 9 and 11, this notch portion 15 is formed by cutting off the upper end surface of the protector side portion 12 downward so that the upper end surface of the protector side portion 12 and the upper surface of the wearing member 2 are substantially flush. Note that the length in the longitudinal direction X of the notch portion 15 is made substantially the same as the length in the longitudinal direction X of the holding portion 27 of the wearing member 2 described later.

[0103] Further, as shown in FIGS. 9 and 10, the mounting member 2 of Example 3 includes a main body portion 21 composed of a bottom surface portion 211 and a pair of side surface portions 212, a clip portion 22 (see FIG. 11(b)), and a restricting portion different from that of Example 1. Specifically, as shown in FIGS. 9 and 10, the mounting member 2 includes a pair of holding portions 27 as a restricting portion that restricts the protector 1 in contact with the bottom contact surface 211a from moving upward and separating from the bottom contact surface 211a.

[0104] Furthermore, the pair of holding portions 27 also functions as a restricting portion that restricts the protector 1 in contact with the side contact surface 212a from moving inward in the width direction Y and separating from the side contact surface 212a. As shown in FIGS. 9 and 10, the holding portion 27 of the mounting member 2 is provided at the upper end of the side surface portion 212 of the main body portion 21 and is formed in a shape that is locked to the protector side portion 12.

[0105] Specifically, as shown in FIG. 11(b), the holding portion 27 is integrally formed by a fitting portion 27a extending inward in the width direction Y from the upper end of the side surface portion 212 and a tip portion 27b vertically provided downward from the tip of the fitting portion 27a.

[0106] The fitting portion 27a is formed to fit into the notch portion 15 of the protector side portion 12. More specifically, as shown in FIG. 11(b), the fitting portion 27a is in a substantially flat plate shape having a thickness that is substantially the same as the vertical length of the notch portion 15, and extends in the width direction Y with a length substantially the same as the thickness of the protector side portion 12.

[0107] On the other hand, as shown in FIG. 11(b), the tip portion 27b is vertically provided with a vertical length that faces the side surface portion 212 across the protector side portion 12 so as to sandwich the protector side portion 12 with the side surface portion 212 of the main body portion 21. Thereby, when the mounting member 2 is assembled to the protector 1, the holding portion 27 of the mounting member 2 fits into the notch portion 15 of the protector 1 and is locked to the protector side portion 12.

[0108] In this way, in the shape maintaining structure of the member to be worn, the protector 1 in contact with the side contact surface 212a is restricted by the tip portion 27b of the holding portion 27 from tilting inward in the width direction Y with the lower end as a fulcrum, and the protector 1 in contact with the bottom contact surface 211a is restricted by the fitting portion 27a of the holding portion 27 from moving upward away from the bottom contact surface 211a. Furthermore, the shape maintaining structure of the member to be worn restricts the movement of the protector 1 in the longitudinal direction X by the notch portion 15 of the protector 1 and the holding portion 27 of the mounting member 2.

[0109] As described above, the shape maintaining structure of the member to be worn in Example 3 includes a restricting portion (holding portion 27) for restricting the mounting member 2 from allowing the protector 1 in contact with the bottom contact surface 211a to move upward away from the bottom contact surface 211a. Furthermore, the shape maintaining structure of the member to be worn includes a restricting portion (holding portion 27) for restricting the mounting member 2 from allowing the protector 1 in contact with the side contact surface 212a to move inward in the width direction Y away from the side contact surface 212a.

[0110] Thereby, the shape maintaining structure of the member to be worn can achieve the same effects as those of the above-described Example 1. Furthermore, since the holding portion 27, which is the restricting portion, is configured to fit into the notch portion 15 provided in the protector 1, the shape maintaining structure of the member to be worn not only restricts the protector 1 from moving away from the side contact surface 212a in the width direction Y, but also can suppress the movement of the protector 1 in at least the longitudinal direction X.

Example

[0111] Regarding Example 4, in which the restricting portion for restricting the protector 1 in contact with the bottom contact surface 211a from moving upward away from the bottom contact surface 211a and the restricting portion for restricting the protector 1 in contact with the side contact surface 212a from moving inward in the width direction Y away from the side contact surface 212a are different from those in the above-described Example 1, will be described with reference to FIGS. 12 and 13.

[0112] Note that FIGS. 12 and 13 are cross-sectional views in a vertical cross-section along the width direction Y. FIG. 12 shows a cross-sectional view of the shape maintenance structure of the member to be attached in Example 4, and FIG. 13 shows a cross-sectional view of the shape maintenance structure of the member to be attached with the lid portion 28 open. In addition, the same configurations as those in the above-described Example 1 are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

[0113] As shown in FIG. 12, the protector 1 of Example 4 is composed of a protector bottom portion 11 and a pair of protector side portions 12. Note that the first insertion hole 13 and the second insertion hole 14 of Example 1 described above are not provided in the protector bottom portion 11 of the protector 1.

[0114] As shown in FIG. 12, the mounting member 2 of Example 4 includes a main body portion 21 composed of a bottom surface portion 211 and a pair of side surface portions 212, a clip portion 22, and a lid portion 28 that covers the main body portion 21. More specifically, as shown in FIGS. 12 and 13, in a vertical cross-section along the width direction Y, the lid portion 28 is integrally formed by a hinge portion 28a connected to one of the side surface portions 212, a lid main body 28b that covers the upper opening in the main body portion 21, and a claw portion 28c locked to the other side surface portion 212.

[0115] As shown in FIGS. 12 and 13, the lid main body 28b is formed in a shape that abuts against the upper end surface of the protector 1 accommodated in the main body portion 21 from above so as to sandwich the protector 1 with the bottom surface portion 211 of the main body portion 21.

[0116] As shown in FIGS. 12 and 13, the claw portion 28c is formed to extend downward from the lid main body 28b and to be lockable to a locked claw 29 provided on the other side surface portion 212. This claw portion 28c is formed to be locked to the locked claw 29 of the main body portion 21 in a state where the lower surface of the lid portion 28 abuts against the upper end surface of the protector 1. Note that, as shown in FIGS. 12 and 13, the locked claw 29 protrudes outward in the width direction Y at the upper portion of the other side surface portion 212.

[0117] The mounting member 2 includes a restricting portion that restricts the protector 1 in contact with the bottom contact surface 211a from moving upward and away from the bottom contact surface 211a, and a restricting portion that restricts the protector 1 in contact with the side contact surface 212a from moving inward in the width direction Y and away from the side contact surface 212a. The restricting portions are constituted by a lid portion 28 that covers the main body portion 21.

[0118] Next, an assembling process for assembling the mounting member 2 to the protector 1 having the above-described configuration will be briefly described. First, the operator assembles the mounting member 2 with the lid portion 28 open from below to the protector 1, brings the bottom contact surface 211a of the mounting member 2 into contact with the contact surface 11a of the protector bottom portion 11, and brings the contact surface 12a of the protector side portion 12 into contact with the side contact surface 212a of the mounting member 2.

[0119] Thereafter, with the contact surface 12a of the protector side portion 12 in contact with the side contact surface 212a of the mounting member 2, the operator closes the lid portion 28 of the mounting member 2 and locks the claw portion 28c of the lid portion 28 to the locked claw 29. At this time, the operator closes the lid portion 28 so that the lower surface of the lid portion 28 contacts the upper end surface of the protector side portion 12. As a result, the lid portion 28 of the mounting member 2 holds the protector 1 in a state where it can slide in the longitudinal direction X in cooperation with the main body portion 21.

[0120] In this way, the shape maintaining structure of the member to be mounted restricts the protector 1 in contact with the side contact surface 212a from tilting inward in the width direction Y with the lower end as a fulcrum by the lid portion 28, and restricts the protector 1 in contact with the bottom contact surface 211a from moving upward and away from the bottom contact surface 211a by the lid portion 28.

[0121] As described above, the shape maintaining structure of the member to be mounted in the fourth embodiment is such that the mounting member 2 includes a restricting portion (lid portion 28) that restricts the protector 1 in contact with the bottom contact surface 211a from moving upward and away from the bottom contact surface 211a, and restricts the protector 1 in contact with the side contact surface 212a from moving away from the side contact surface 212a in the width direction Y.

[0122] As a result, the shape maintaining structure of the member to be attached can achieve the same effects as those of the above-described first embodiment. Further, since the restricting portion is constituted by the lid portion 28, the lid portion 28 can prevent the mounting member 2 from separating from the contact surfaces (the bottom contact surface 211a and the side contact surface 212a) so that the protector 1 detaches from the main body portion 21 through the opening of the main body portion 21.

[0123] As a result, the shape maintaining structure of the member to be attached can stably maintain the state where the protector 1 is in contact with the contact surfaces (the bottom contact surface 211a and the side contact surface 212a) of the mounting member 2. Therefore, the shape maintaining structure of the member to be attached can surely maintain the desired cross-sectional shape of the protector 1.

[0124] Furthermore, since the movement of the protector 1 in the longitudinal direction X is not restricted, the shape maintaining structure of the member to be attached can arrange the mounting member 2 at a desired position in the longitudinal direction X while maintaining the desired cross-sectional shape of the protector 1.

[0125] In the correspondence between the configuration of this invention and the above-described embodiment, The plate material of this invention corresponds to the thermoplastic resin foam sheet of the embodiment, Similarly hereinafter, The predetermined direction corresponds to the longitudinal direction X, The member to be attached corresponds to the protector 1, The orthogonal direction corresponds to the width direction Y and the vertical direction, The contact surface corresponds to the bottom contact surface 211a and the side contact surface 212a, The main body portion corresponds to the main body portion 21, The restricting portion corresponds to the wall portion 23, the locking portion 24, the holding portion 26, the holding portion 27, and the lid portion 28, The locking portion corresponds to the locking portion 24, the holding portion 26, and the holding portion 27, The insertion hole corresponds to the second insertion hole 14, The portion to be fitted corresponds to the notch portion 15, The attachment portion corresponds to the clip portion 22, but The present invention is not limited to the configurations of the above-described embodiments, and many embodiments can be obtained.

[0126] For example, in the above-described embodiment, the protector 1 has a substantially U-shaped groove cross-section with corners, but is not limited thereto. As long as it has an open cross-section shape extending in the longitudinal direction X, for example, it may be a protector having a substantially U-shaped cross-section with a curved portion. Alternatively, it may be a protector having a substantially L-shaped cross-section extending in the longitudinal direction X.

[0127] Also, although the protector 1 is a protector for protecting the wire harness WH, it is not limited thereto, and it may be a protector for protecting an electric wire or a cable that mechanically transmits movement. Also, although the protector bottom 11 and the protector side 12 are formed by bending a single thermoplastic resin foam sheet, it is not limited thereto, and they may be a protector bottom and a protector side formed by bending the thermoplastic resin foam sheet a plurality of times and having the thermoplastic resin foam sheets overlapping double.

[0128] Also, although the protector 1 is configured to be accommodated in the main body portion 21 of the mounting member 2, it is not limited thereto. For example, as shown in FIG. 14, which is an explanatory diagram for explaining the shape maintaining structure of another mounted member in a vertical cross-section along the width direction Y, the main body portion 21 of the mounting member 2 may be configured to be accommodated in the protector 1.

[0129] In this case, as shown in FIG. 14(a), the upper surface of the protector bottom 11 of the protector 1 becomes the contact surface 11b, and the surface of the protector side 12 (the main surface on the inner side in the width direction Y) continuous with the upper surface of the protector bottom 11 becomes the contact surface 12b. On the other hand, as shown in FIG. 14(a), the lower surface of the bottom portion 211 of the mounting member 2 becomes the bottom contact surface 211b, and the surface of the side portion 212 (the main surface on the outer side in the width direction Y) continuous with the lower surface of the bottom portion 211 becomes the side contact surface 212b.

[0130] Further, instead of the locking portion 24 which is the restricting portion of the first embodiment, as shown in Fig. 14(a), a restricting portion is constituted by a locking portion 31 which protrudes downward from the bottom surface portion 211 of the mounting member 2 and is locked to the protector bottom portion 11.

[0131] In addition, instead of the pair of wall portions 23 which are the restricting portions of the first embodiment, as shown in Fig. 14(a), after extending outward in the width direction Y from the upper end of the side surface portion 212, a restricting portion is constituted by a substantially flat plate-shaped wall portion 32 which extends downward. Thereby, the shape maintaining structure of the member to be mounted can achieve the same effects as those of the first embodiment described above.

[0132] Alternatively, for example, instead of the holding portion 26 which is the restricting portion of the second embodiment, as shown in Fig. 14(b), after extending outward in the width direction Y from the upper end of the side surface portion 212, a restricting portion may be constituted by a holding portion 33 in which claw portions are formed downward. Thereby, the shape maintaining structure of the member to be mounted can achieve the same effects as those of the second embodiment described above.

[0133] Also, in the first embodiment, the pair of wall portions 23 and the locking portion 24 are used as the restricting portions of the mounting member 2, but it is not limited thereto. For example, as shown in Fig. 15(a) which is an explanatory diagram for explaining the shape maintaining structure of another member to be mounted in a vertical cross-section along the width direction Y, a mounting member provided with only the locking portion 24 may be used.

[0134] Also, in the first and second embodiments, the clip portion 22 and the melt 25 of the mounting member 2 are integrally formed with the main body portion 21, but it is not limited thereto, and the clip portion and the melt may be integrally formed separately from the main body portion 21. In this case, after inserting through the insertion hole provided in the main body portion 21, the tip of the melt is melted to form a locking portion locked to the protector 1.

[0135] In addition, in the second and third embodiments, the restricting portions (holding portions 26 and 27) that are locked to the protector side portion 12 from above are used, but the present invention is not limited to this. For example, as shown in FIG. 15(b), a locking portion 34 that fits into a locking hole 16 provided in the protector side portion 12 of the protector 1 and is locked to the protector side portion 12 may be used to form the restricting portion.

[0136] In addition, in the fourth embodiment described above, the lid portion 28 is such that one end in the width direction Y is connected to the main body portion 21 via the hinge portion 28a and the other end in the width direction Y is locked to the side surface portion 212 of the main body portion 21. However, the present invention is not limited to this, and the lid portion may be configured separately from the main body portion 21 and both ends in the width direction Y may be locked to the side surface portion 212 of the main body portion 21.

[0137] In addition, the restricting portions (wall portion 23, locking portion 24, holding portion 26, holding portion 27) that restrict the protector 1 in contact with the side contact surface 212a from separating from the side contact surface 212a in the width direction Y are arranged opposite to each other in the width direction Y, but the present invention is not limited to this.

[0138] For example, as shown in FIG. 16 showing an external perspective view of the shape maintaining structure of another mounted member, the mounting member 2 of the second embodiment may be composed of a bottom surface portion 211 that is long in the longitudinal direction X and side surface portions 212 that are arranged in a staggered pattern so as to be alternately positioned in the width direction Y along the longitudinal direction X, and holding portions 26 that are provided on the side surface portions 212 and arranged in a staggered pattern.

[0139] Thereby, even if the protector 1 is long in the longitudinal direction X, the shape maintaining structure of the mounted member can suppress an increase in the weight of the mounting member 2 and stably maintain the desired cross-sectional shape of the protector 1.

[0140] In addition, the mounting member 2 is provided with a clip portion 22 as a mounting portion for mounting to other members, but the present invention is not limited to this, and any appropriate shape may be used as long as it can be mounted to other members.

[0141] For example, as shown in FIG. 17(a) which is an explanatory diagram for explaining the shape maintaining structure of another member to be worn, instead of the clip portion 22 in the wearing member 2 of the first embodiment, a substantially flat plate portion extending outward in the width direction Y from the lower portion of the main body portion 21 and having a bolt hole 35a through which a bolt is inserted and opened substantially at the center in plan view may be provided as an attachment portion.

[0142] Also, although the protector 1 that protects the substantially linearly extending portion of the wire harness WH and the wearing member 2 attached thereto are used, it is not limited thereto. For example, as shown in FIG. 17(b) which is an explanatory diagram for explaining the shape maintaining structure of another member to be worn, a protector 4 that protects the wire harness WH may be provided along the curved portion of the wire harness WH that is routed curvedly from the longitudinal direction X to the width direction Y. In this case, the wearing member 5 is formed in a shape corresponding to the shape of the protector 4.

[0143] Specifically, as shown in FIG. 17(b), the protector 4 is formed in a curved shape along the curved portion of the wire harness WH by connecting a protector extending in the longitudinal direction X, a protector disposed obliquely with respect to the portion extending in the longitudinal direction X, and a protector extending in the width direction Y in plan view. Note that the protector 4 is composed of a protector bottom portion 41 and a pair of protector side portions 42, similar to the above-described embodiment.

[0144] On the other hand, as shown in FIG. 17(b), the wearing member 5 includes a main body portion 51 formed along the curved portion of the protector 4, a locking portion 52 which is a regulating portion locked to the protector bottom portion 41, and a holding portion 53 locked to the protector side portion 42.

[0145] Note that although detailed illustration of the main body portion 51 is omitted, similar to the above-described embodiment, it is formed of a bottom surface portion 511 formed along the lower surface of the protector bottom portion 41 and a pair of side surface portions 512 formed along the protector side portion 42.

[0146] As a result, the shape maintaining structure of the member to be worn can maintain the desired cross-sectional shape of the protector 4 and reinforce the curved portion of the protector 4. Therefore, the shape maintaining structure of the member to be worn can prevent the protector 4 from being deformed by the reaction force of the curved wire harness WH.

[0147] Further, although it has been assumed that the protector 1 and the mounting member 2 are assembled by an operator, the present invention is not limited to this, and the protector 1 and the mounting member 2 may be automatically assembled using a dedicated device. Further, the restricting portion of the mounting member 2 is not limited to the restricting portions described in the above-described first to fourth embodiments and the combinations of the restricting portions described as another embodiment, and the above-described restricting portions may be appropriately combined.
