Mode for Carrying Out the Invention

[0009] Hereinafter, with reference to the drawings, a fixing structure according to an embodiment of the present invention will be described. Note that the following embodiments are merely examples, and the fixing structure of the present invention is not limited to the following embodiments.

[0010] In this specification, expressions such as "perpendicular to A" and similar expressions do not refer only to a direction that is completely perpendicular to A, but include a direction that is substantially perpendicular to A. Also, in this specification, expressions such as "parallel to B" and similar expressions do not refer only to a direction that is completely parallel to B, but include a direction that is substantially parallel to B. Further, in this specification, expressions such as "C shape" and similar expressions do not refer only to a complete C shape, but include a shape that reminds one of a C shape visually (substantially C shape).

[0011] As shown in FIG. 1, the fixing structure 1 of the present embodiment includes a long member 2 and a mounting member 3 to which the long member 2 is connected and which is mounted in a mounting groove B2 of a mounting target B. Further, in the present embodiment, the fixing structure 1 further includes a clip 4 attached along the direction around the axis X of the long member 2 on the outer periphery of the mounting member 3. Note that the clip 4 in the fixing structure 1 has an arbitrary configuration and does not necessarily need to be provided.

[0012] The fixing structure 1 is a structure for fixing the long member 2 to the object to be attached B. The fixing structure 1 attaches each member such as the long member 2 and the attachment member 3 to a predetermined installation object (not shown) via the object to be attached B. In the present embodiment, the fixing structure 1 fixes a long member assembly A including the long member 2, the attachment member 3, and the clip 4 to a bracket that is the object to be attached. In the present embodiment, the long member assembly A is a control cable assembly and is attached to a vehicle body that is the installation object via the object to be attached B. Note that the installation object by the fixing structure 1 is not limited to the vehicle body, and the long member assembly A is not limited to the control cable assembly.

[0013] The object to be attached B is a part to which the attachment member 3 is attached. By attaching the attachment member 3 to the object to be attached B, the long member assembly A is attached to an installation object such as a vehicle body. In the present embodiment, the object to be attached B is configured as a plate-shaped attachment part (bracket) as shown in FIG. 1. The structure of the object to be attached B is not particularly limited, and the object to be attached B may be a plate-shaped member or a box-shaped member having a plate-shaped wall part. Note that the object to be attached B may be detachably attached to a vehicle body or the like by a fixing member such as a bolt and nut, or may be integrally provided on an installation object such as a vehicle body.

[0014] The object B to be attached is a plate-like member or part having an attachment groove B2 notched in a groove shape in the first direction D1 from the edge B1 of the object B to be attached, as shown in FIGS. 1 and 13. The edge B1 is the edge portion (the upper edge in FIG. 1) of the plate-like object B to be attached that extends in the thickness direction of the object B to be attached. The attachment groove B2 is open at the edge B1 so that the attachment member 3 can be inserted. In the present embodiment, as will be described later, when the attachment member 3 to which the clip 4 is attached is attached to the attachment groove B2, the first engaging portion 41 and the second engaging portion 42 of the clip 4 abut against the opening edge E provided at the edge B1 while the attachment member 3 is pushed into the attachment groove B2. In this specification, the height direction (the direction away from the edge B1) of the attachment groove B2 from the edge B1 of the object B to be attached is referred to as the first direction D1, the thickness direction of the plate-like object B to be attached is referred to as the second direction D2, and the groove width direction of the attachment groove B2, which is perpendicular to both the first direction D1 and the second direction D2, is referred to as the third direction D3. Also, among the first direction D1, the direction in which the attachment member 3 is inserted into the attachment groove B2 is referred to as the insertion direction D11, and the direction in which the attachment member 3 detaches from the attachment groove B2 is referred to as the detachment direction D12.

[0015] The shape and structure of the attachment groove B2 are not particularly limited as long as the attachment member 3 can be attached. In the present embodiment, as shown in FIGS. 1 and 13, the attachment groove B2 of the object B to be attached has a first engaged portion B21 and a second engaged portion B22 that are spaced apart from each other in the third direction D3, which is the groove width direction of the attachment groove B2. Also, as shown in FIGS. 1 and 13, the attachment groove B2 further has an insertion portion B23 into which the attachment member 3 is inserted and an installation portion B24 where the attachment member 3 is installed. In the present embodiment, the attachment groove B2 is shown as a portion notched in a substantially U shape from the edge B1 of the plate-like object B to be attached.

[0016] The insertion part B23 is a part that serves as an entrance through which the mounting member 3 is inserted during the process of mounting the mounting member 3 on the installation part B24 of the object B to be mounted. In the present embodiment, on the end part of the insertion part B23 side of the object B to be mounted, tapered parts T, T are formed such that the interval in the third direction D3 with respect to each other (the left - right direction in FIG. 13) becomes narrower in the insertion direction D11. In the present embodiment, when the mounting member 3 to which the clip 4 is attached is attached to the mounting groove B2, the first inclined surface 41a of the first engaging part 41 and the second inclined surface 42a of the second engaging part 42, which will be described later, abut against the tapered part T provided on the opening edge E of the mounting groove B2. When the tapered part T is provided, it is possible to facilitate the movement of the mounting member 3 to which the clip 4 is attached in the insertion direction D11.

[0017] The installation part B24 is a part where the mounting member 3 is installed. In the present embodiment, the shaft part 33a (see FIGS. 2 and 3) of the mounting member 3 is installed in the installation part B24. The shape of the installation part B24 is preferably a shape that conforms to the outer shape of the shaft part 33a. However, the shape of the installation part B24 is not particularly limited as long as the mounting member 3 (shaft part 33a) can be installed.

[0018] The first engaged part B21 engages with the first engaging part 41 of the clip 4. When the first engaging part 41 of the clip 4 engages with the first engaged part B21 of the object B to be mounted, the movement of the clip 4 in the detachment direction D12 is suppressed. As a result, the movement of the mounting member 3 to which the clip 4 is attached in the detachment direction D12 is suppressed. The shape of the first engaged part B21 is not particularly limited as long as it can engage with the first engaging part 41 of the clip 4 and suppress the movement of the clip 4 and the mounting member 3 in the detachment direction D12, and can be appropriately changed according to the shape of the first engaging part 41 of the clip 4.

[0019] In this embodiment, as shown in FIGS. 1 and 13, the first engaged portion B21 is formed as a recess that is recessed in the third direction D3 with respect to the inner surface extending in the first direction D1 of the installation portion B24. In this embodiment, the first engaged portion B21 has a first engaging wall portion B211 provided on the detachment direction D12 side and a second engaging wall portion B212 provided on the insertion direction D11 side, as shown in FIGS. 1 and 13. When a force for moving the attachment member 3 in the detachment direction D12 is applied, the first engaging wall portion B211 engages with the first engaging portion 41 of the clip 4 attached to the attachment member 3 to suppress the detachment of the attachment member 3. The first engaging wall portion B211 only needs to be provided so as to be able to suppress the detachment of the attachment member 3, and is not limited to the illustrated inclination angle. The second engaging wall portion B212 faces the first inclined surface 41a of the first engaging portion 41 described later. The second engaging wall portion B212 may be in contact with or separated from the first inclined surface 41a of the first engaging portion 41 in a state where the attachment member 3 is attached to the attachment target B.

[0020] The second engaged portion B22 engages with the second engaging portion 42 of the clip 4. When the second engaging portion 42 of the clip 4 engages with the second engaged portion B22 of the attachment target B, the movement of the clip 4 in the detachment direction D12 is suppressed. Thereby, the movement of the attachment member 3 to which the clip 4 is attached in the detachment direction D12 is suppressed. The shape of the second engaged portion B22 is not particularly limited as long as it can engage with the second engaging portion 42 of the clip 4 and suppress the movement of the clip 4 and the attachment member 3 in the detachment direction D12, and can be appropriately changed according to the shape of the second engaging portion 42 of the clip 4.

[0021] In the present embodiment, as shown in FIGS. 1 and 13, the second engaged portion B22 is formed as a recess that is recessed in the third direction D3 with respect to the inner surface extending in the first direction D1 of the installation portion B24. In the present embodiment, as shown in FIGS. 1 and 13, the second engaged portion B22 has a first engaging wall portion B221 provided on the detachment direction D12 side and a second engaging wall portion B222 provided on the insertion direction D11 side. When a force for moving the attachment member 3 in the detachment direction D12 is applied, the first engaging wall portion B221 engages with the second engaged portion 42 of the clip 4 attached to the attachment member 3 to suppress the detachment of the attachment member 3. The first engaging wall portion B221 only needs to be provided so as to be able to suppress the detachment of the attachment member 3, and is not limited to the illustrated inclination angle. The second engaging wall portion B222 faces the second inclined surface 42a of the second engaged portion 42 described later. The second engaging wall portion B222 may be in contact with or separated from the second inclined surface 42a of the second engaged portion 42 in a state where the attachment member 3 is attached to the attachment target B.

[0022] The shapes and sizes of the first engaged portion B21 and the second engaged portion B22 are not particularly limited as long as they can engage with the first engaged portion 41 and the second engaged portion 42 of the clip 4, respectively, and do not need to have shapes or sizes corresponding to the first engaged portion 41 and the second engaged portion 42 of the clip 4. Further, the first engaged portion B21 and the second engaged portion B22 may have corresponding shapes to each other or may have different shapes from each other.

[0023] The long member 2 is a long member that is connected to the attachment member 3 and fixed to the attachment target B via the attachment member 3. The shape and structure of the long member 2 are not particularly limited as long as it is a long member that is connected to the attachment member 3 and fixed to the attachment target B via the attachment member 3. In the present embodiment, the long member 2 is a control cable that transmits an operating force, but the long member may be an electrical cable.

[0024] In this embodiment, as shown in FIG. 1, the long member 2 has a first long member 21 and a second long member 22. The first long member 21 and the second long member 22 are connected in the second direction D2 (in this embodiment, the X-axis direction is the same as the second direction D2) by the mounting member 3. In this embodiment, the first long member 21 is the outer casing of the control cable, and the second long member 22 is a guide pipe through which the inner cable 23 is inserted. In this embodiment, the inner cable 23 is inserted through the first long member 21, the second long member 22, and the mounting member 3. One end of the inner cable 23 is connected to an operating portion (not shown) such as a shift lever, and the other end is connected to an operated portion (not shown) such as a transmission via a rod R. By operating the operating portion, the inner cable 23 is operated, and the operating force of the inner cable 23 is transmitted to the operated portion via the rod R. One end of the first long member 21 is attached to the mounting member 3, and the other end of the first long member 21 (not shown) is attached to a predetermined mounting site on the operating portion side. Also, one end of the second long member 22 is swingably attached to the mounting member 3, and the other end of the second long member 22 (not shown) has a rod R connected to the end of the inner cable 23 led out on the operated portion side. Note that in this embodiment, two long members 21 and 22 are connected to the mounting member 3, but the number of long members connected to the mounting member 3 is not limited and may be one.

[0025] The mounting member 3 is a member to which the long member 2 is connected and which is attached to a mounting groove B2 of the mounting object B. In the present embodiment, the mounting member 3 is formed in a cylindrical shape, and a part of the long member 2 is inserted therein. More specifically, a part of the first long member 21 and the second long member 22 is inserted into the cylindrical mounting member 3, and the first long member 21 and the second long member 22 are connected to each other by the mounting member 3. The mounting member 3 holds the long member 2 at a predetermined position of the installation target by being attached to the mounting object B with the long member 2 connected. Here, the "cylindrical shape" means having a substantially cylindrical shape such as a cylindrical shape or a rectangular tube shape having an internal space capable of connecting the long member 2. Further, the cylindrical mounting member 3 may have a plurality of portions different in outer diameter and outer shape in the axial X direction, and the outer peripheral surface of the mounting member 3 may have irregularities along the axial X direction and the circumferential direction around the axis X.

[0026] The shape and structure of the mounting member 3 are not particularly limited as long as the long member 2 can be connected and the mounting member 3 can be attached to the mounting object B. In the present embodiment, as shown in FIGS. 7 and 8, the mounting member 3 includes a clamping portion 33 that clamps the mounting object B in a second direction D2 that is the thickness direction of the mounting object B. Further, in the present embodiment, the mounting member 3 includes a connecting portion 32 to which the long member 2 is connected, and a mounted portion 31 that is provided adjacent to the clamping portion 33 in the second direction D2 and to which the clip 4 is mounted. Further, in the present embodiment, as shown in FIGS. 6 to 9, between the clamping portion 33 and the mounted portion 31 in the second direction D2 (in the present embodiment, a first wall body 33b described later), a mounting portion 43 of the clip 4 is provided on the outer surface of the mounted portion 31 so as to be engageable in the second direction D2. The mounting member 3 is provided with a protruding portion 34 that protrudes radially outward of the mounting member 3.

[0027] The connecting portion 32 is the portion where the long member 2 is connected. In the present embodiment, as shown in FIGS. 1 and 2, the connecting portion 32 is provided on one end side in the axial direction X of the mounting member 3, and includes a cylindrical first connecting portion 321 to which the first long member 21 is connected, and a cylindrical second connecting portion 322 provided on the other end side in the axial direction X of the mounting member 3 to which the second long member 22 is connected. In the present embodiment, a mounted portion 31 and a clamping portion 33 are provided between the first connecting portion 321 and the second connecting portion 322 in the axial direction X. Further, in the present embodiment, the mounting member 3 has openings at both ends in the axial direction X, and the openings at both ends communicate with each other to form an inner space of the mounting member 3. In the present embodiment, the first long member 21 and the second long member 22 connected to the connecting portion 32 are arranged in the inner space of the mounting member 3, and the inner cable 23 is inserted therethrough. The shape and structure of the connecting portion 32 are not particularly limited as long as the long member 2 can be connected.

[0028] When the mounting member 3 is fixed to the mounting object B, the clamping portion 33 clamps the mounting object B in the second direction D2. Thereby, the movement of the mounting member 3 in the second direction D2 is suppressed, and the long member 2 is held at a predetermined position and wiring route with respect to an installation object such as a vehicle body.

[0029] In the present embodiment, as shown in FIGS. 2 and 3, the clamping portion 33 includes a first wall body 33b having a first opposing surface F1 facing one surface of the mounting object B, and a second wall body 33c having a second opposing surface F2 facing the other surface of the mounting object B. Further, in the present embodiment, the clamping portion 33 includes a shaft portion 33a inserted into the mounting groove B2 of the mounting object B. The shaft portion 33a is provided between the first wall body 33b and the second wall body 33c in the second direction D2, and connects the first wall body 33b and the second wall body 33c in the second direction D2. In the present embodiment, the shaft portion 33a is formed in a cylindrical shape having an outer diameter corresponding to the groove width in the third direction D3 of the mounting groove B2. The first wall body 33b and the second wall body 33c are arranged on both sides in the second direction D2 (axial direction X) of the shaft portion 33a, and can be engaged with both surfaces of the plate-shaped mounting object B in the second direction D2.

[0030] The first wall body 33b is provided on one side (the mounted portion 31 side) in the second direction D2 of the shaft portion 33a, and is formed wider than the groove width of the mounting groove B2. Thereby, the first wall body 33b (the first opposing surface F1) abuts against one surface of the object B to be mounted, and suppresses the mounting member 3 from moving in one direction in the second direction D2. In the present embodiment, the first wall body 33b is a plate-like portion provided between the mounted portion 31 and the shaft portion 33a in the second direction D2. In the present embodiment, the protruding portion 34 is provided on the first wall body 33b. In the present embodiment, as shown in FIGS. 8, 15, and 17, the first opposing surface F1 is provided at a distance in the third direction D3 perpendicular to the first direction D1 and the second direction D2, and has a plurality of first protruding portions PR1 protruding toward the second opposing surface F2. The first protruding portion PR1 will be described later.

[0031] The second wall body 33c is provided on the other side (the side opposite to the mounted portion 31) in the second direction D2 of the shaft portion 33a, and is formed wider than the groove width of the mounting groove B2. Thereby, the second wall body 33c (the second opposing surface F2) abuts against the other surface of the object B to be mounted, and suppresses the mounting member 3 from moving in the other direction in the second direction D2. In the present embodiment, the second wall body 33c is a plate-like portion provided between the shaft portion 33a and the second connecting portion 322. In the present embodiment, as shown in FIGS. 6, 7, and 9, the second wall body 33c has a pair of notches N at the end on the detachment direction D12 side (the upper end side in FIG. 6) through which the first engaging portion 41 and the second engaging portion 42 of the clip 4 can pass in the second direction D2. Between the pair of notches N in the width direction D3, a detachment preventing protrusion P protruding in the detachment direction D12 is provided with respect to the end of the notch N on the detachment direction D12 side. In the present embodiment, as shown in FIGS. 8, 16, and 17, the second opposing surface F2 is provided at a distance in the third direction D3, and has a plurality of second protruding portions PR2 protruding toward the first opposing surface F1. The second protruding portion PR2 will be described later.

[0032] As will be described later, as shown in FIGS. 2, 3, 10(A) to 12, the clip 4 can be attached to the attachment member 3 from the side of the second wall body 33c toward the first wall body 33b. The attachment member 3 has a chamfered portion CH on the outer periphery of the surface of the second wall body 33c on the side opposite to the mounted portion 31 in the second direction D2 (see FIGS. 7 and 8). When the chamfered portion CH is provided on the outer periphery of the second wall body 33c, as will be described later, it becomes easier to move the clip 4 from the side of the second wall body 33c toward the mounted portion 31 of the attachment member 3. In the present embodiment, the chamfered portion CH is provided on the entire outer periphery of the second wall body 33c, but it may be provided at least at a portion that contacts when the clip 4 crosses the second wall body 33c in the second direction D2. Note that the chamfered portion may also be provided on the outer periphery of the first wall body 33b. In this case, it becomes easier to move the clip 4 across the first wall body 33b in the second direction D2 toward the mounted portion 31.

[0033] The mounted portion 31 is a portion where the clip 4 is attached. Specifically, as shown in FIGS. 2 and 3, a mounting portion 43 of the clip 4 to be described later is attached to the mounted portion 31 so as to be relatively rotatable about the axis X of the attachment member 3. Thereby, even when a force is applied to the long member 2, the clip 4 and the attachment member 3 are less likely to come off from the attachment target B.

[0034] The size and shape of the mounted portion 31 are not particularly limited as long as the mounting portion 43 can be attached to the mounted portion 31 so as to be relatively rotatable about the axis X of the attachment member 3. In the present embodiment, the mounted portion 31 has an outer peripheral surface that at least partially corresponds to the shape of the mounting portion 43 of the clip 4. Specifically, it is preferable that the portion of the mounted portion 31 facing the mounting portion 43 has at least a partially arcuate surface so that the attachment member 3 can rotate relative to the clip 4 about the axis X. In this case, the mounting portion 43 attached to the mounted portion 31 can rotate smoothly.

[0035] In this embodiment, as shown in FIG. 6, the mounting member 3 has a rotation restricting portion RR. In this embodiment, the rotation restricting portion RR is provided between one end and the other end of a substantially U-shaped mounting portion 43 attached to the mounted portion 31. Here, one end of the mounting portion 43 is a portion near the portion where the first engaging portion 41 is provided, and the other end of the mounting portion 43 is a portion near the portion where the second engaging portion 42 is provided.

[0036] As will be described later, the rotation restricting portion RR restricts the relative rotation of the mounting member 3 with respect to the clip 4 within a predetermined range. Thereby, excessive relative rotation of the mounting member 3 due to torsion or the like of the long member 2 is suppressed. In this embodiment, the rotation restricting portion RR is provided at a predetermined interval in the direction around the axis X between the rotation restricting portion RR and the clip 4. When the mounting member 3 rotates relative to the clip 4 by a predetermined amount or more, the rotation restricting portion RR abuts against the clip 4, and the relative rotation of the mounting member 3 with respect to the clip 4 is restricted within a predetermined range. The shape and structure of the rotation restricting portion RR are not particularly limited as long as the relative rotation of the mounting member 3 with respect to the clip 4 can be restricted within a predetermined range. In this embodiment, the rotation restricting portion RR is a protruding portion that protrudes radially outward (toward the detachment direction D12) from the outer periphery of the cylindrical portion having the mounted portion 31, and is disposed between a pair of knob portions 45a and 45b described later in the direction around the axis X.

[0037] The protruding portion 34 engages with the mounting portion 43 in the second direction D2, and suppresses the clip 4 from detaching from the mounting member 3 in the second direction D2. The protruding portion 34 is provided between the clamping portion 33 and the mounted portion 31 in the second direction D2. The portion where the protruding portion 34 is provided is not particularly limited as long as it can engage with the mounting portion 43 in the second direction D2 and suppress the clip 4 from detaching from the mounting member 3 in the second direction D2. In this embodiment, the protruding portion 34 is provided on a first wall body 33b provided at the boundary portion between the clamping portion 33 and the mounted portion 31 in the second direction D2. However, the protruding portion may be provided separately from the first wall body 33b.

[0038] The protruding portion 34 protrudes radially outward of the mounting member 3 with respect to the outer surface of the mounted portion 31. This enables engagement with the clip 4 attached to the mounted portion 31 in the second direction D2. More specifically, when the clip 4 attached to the mounted portion 31 is in an unloaded state (natural state), the protruding portion 34 protrudes so as to engage with the mounting portion 43 of the clip 4 in the second direction D2. That is, when the mounting member 3 and the clip 4 are viewed in the second direction D2, the protruding portion 34 protrudes so as to at least partially overlap the mounting portion 43 of the clip 4 (see FIGS. 1, 5, and 6). Note that the protruding width of the protruding portion 34 radially outward is not particularly limited as long as it is a protruding width that allows the clip 4 to be elastically deformed and hooked on the protruding portion 34 for attachment, as described later.

[0039] In the present embodiment, the protruding portion 34 is formed continuously and is one round larger than the outer periphery of the mounting portion 43 in a region corresponding to the region where the arc surface of the mounting portion 43 is formed so as to engage with the entire portion where the curved arc surface of the substantially U-shaped mounting portion 43 is formed in the second direction D2. In this case, it is possible to further suppress the clip 4 from detaching in the second direction D2. In the present embodiment, in the protruding portion 34 (the first wall body 33b), the vicinity of the first knob portion 45a and the second knob portion 45b has a smaller protruding width or does not protrude with respect to the outer periphery of the mounted portion 31 so that the first knob portion 45a and the second knob portion 45b of the clip 4 can easily pass through the first wall body 33b in the second direction D2 (see FIG. 5). Note that the protruding portion may protrude partially (fragmentarily) in the circumferential direction around the axis X instead of protruding continuously in the circumferential direction around the axis X as in the present embodiment.

[0040] The clip 4 is attached to the mounting member 3, and when the mounting member 3 is attached to the attachment target B, the first engaging portion 41 and the second engaging portion 42 provided on the clip 4 engage with the attachment target B, thereby suppressing the mounting member 3 from coming off the attachment target B. As shown in FIG. 1, the clip 4 is attached to the outer periphery of the mounting member 3 along the circumferential direction around the axis X of the long member 2.

[0041] In the present embodiment, as shown in FIGS. 1, 4, and 5, the clip 4 engages with the first engaged portion B21 of the mounting groove B2 (see FIG. 14), and has a first engaging portion 41 that suppresses the movement of the mounting member 3 and the clip 4 in the detachment direction D12. The second engaging portion 42 is provided at a distance from the first engaging portion 41 in the third direction D3, engages with the second engaged portion B22 of the mounting groove B2, and suppresses the movement of the mounting member 3 and the clip 4 in the detachment direction D12. Further, the clip 4 includes a mounting portion 43 that extends along the circumferential direction of the mounting member 3 and is mounted on the mounted portion 31. In the present embodiment, the clip 4 includes a connecting portion 44 that connects the first engaging portion 41 and the second engaging portion 42 to each other in the third direction D3. In the present embodiment, the clip 4 includes a first knob portion 45a and a second knob portion 45b that can be operated so that the first engaging portion 41 and the second engaging portion 42 approach each other in the third direction D3.

[0042] The overall shape and structure of the clip 4 are not particularly limited as long as the clip 4 has the first engaging portion 41, the second engaging portion 42, and the mounting portion 43. In the present embodiment, as shown in FIGS. 4 and 5, the portion constituted by the first engaging portion 41, the mounting portion 43, and the second engaging portion 42 of the clip 4 is formed to be substantially U-shaped when viewed in the axial X direction. In the present specification, the substantially U-shaped or U-shaped means that the overall schematic shape includes a U-shaped portion, and is not limited to a strict U-shaped, and may have another part in addition to the U-shaped portion of the schematic shape. In the present embodiment, the clip 4 is annular when viewed in the axial X direction including the connecting portion 44. The material of the clip 4 is not particularly limited, but is preferably made of an elastically deformable synthetic resin or metal.

[0043] The mounting portion 43 is a portion that is mounted on the mounted portion 31 of the mounting member 3. The mounting portion 43 extends along the circumferential direction of the mounted portion 31 of the mounting member 3 and is mounted along at least a part of the outer circumference of the mounted portion 31. The mounting portion 43 is mounted so as to be relatively rotatable about the axis X of the mounting member 3 with respect to the mounted portion 31. As a result, although details will be described later, even if the mounting member 3 rotates in the direction around the axis X due to torsion or the like of the long member 2, the rotation of the mounting member 3 is suppressed from being transmitted to the clip 4, and the engagement between the clip 4 and the mounting target B is suppressed from being released.

[0044] When the mounting portion 43, the mounting member 3, and the clip 4 are mounted in the mounting groove B2 of the mounting target B, the mounting portion 43 is configured to be elastically deformable so that the distance between the first engaging portion 41 and the second engaging portion 42 becomes shorter in the third direction D3. Since the mounting portion 43 is elastically deformable, as will be described later, after the mounting portion 43 is deformed so that the distance in the third direction D3 between the first engaging portion 41 and the second engaging portion 42 becomes shorter, when the first engaging portion 41 and the second engaging portion 42 reach the positions of the first engaged portion B21 and the second engaged portion B22, the mounting portion 43 elastically returns. As a result, the first engaging portion 41 and the first engaged portion B21 can be engaged, the second engaging portion 42 can be engaged with the second engaged portion B21, and the movement of the mounting member 3 in the detachment direction D12 is suppressed (see FIG. 14). In the present embodiment, as shown in FIGS. 5 and 6, in a state where the clip 4 is mounted on the mounting member 3, there is a space S having a predetermined size between the mounted portion 31 of the mounting member 3 and the inner surface of the end region of the mounting portion 43. Due to this space S, when the first engaging portion 41 and the second engaging portion 42 approach each other in the third direction D3, both end regions of the mounting portion 43 in the vicinity of the first engaging portion 41 and the second engaging portion 42 can bend inward.

[0045] The overall schematic shape of the mounting portion 43 is not particularly limited as long as it can be mounted on the mounted portion 31 of the mounting member 3. In the present embodiment, as shown in FIGS. 4 and 5, the mounting portion 43 is formed in a substantially U shape. In the present embodiment, one end and the other end of the mounting portion 43 formed in a substantially U shape are provided spaced apart from each other with a space in the circumferential direction of the mounting member 3. Here, one end of the mounting portion 43 is a portion in the vicinity of the portion where the first engaging portion 41 is provided (the portion where the first knob portion 45a described later is provided), and the other end of the mounting portion 43 is a portion in the vicinity of the portion where the second engaging portion 42 is provided (the portion where the second knob portion 45b is provided). In the present embodiment, one end and the other end of the mounting portion 43 provided spaced apart in the direction around the axis X are connected by a connecting portion 44, and the entire clip 4 is formed in an annular shape.

[0046] Also, in the present embodiment, the portion of the mounting portion 43 facing the mounted portion 31 has at least a partially arcuate surface. That is, the inner surface of the mounting portion 43 does not have a portion that engages with the outer surface of the mounted portion 31 in the direction around the axis X of the mounting member 3 at the portion where it faces the outer surface of the mounted portion 31 in a contactable manner. Thereby, the mounting portion 43 can rotate relative to the mounted portion 31 smoothly.

[0047] The first engaging portion 41 engages with the first engaged portion B21 of the mounting groove B2 to suppress the movement of the mounting member 3 and the clip 4 in the detachment direction D12. As shown in FIGS. 4 and 5, the first engaging portion 41 is provided on one end side of the mounting portion 43 in the circumferential direction of the mounting member 3. Further, as shown in FIGS. 1 and 4, the first engaging portion 41 is provided to protrude in the second direction D2 from one end side of the mounting portion 43. Thereby, in the state where the clip 4 is attached to the mounting member 3, the first engaging portion 41 is disposed at a position corresponding to the position of the shaft portion 33a that enters the mounting groove B2 in the axis X direction (see FIG. 3). Thereby, when the shaft portion 33a is disposed in the mounting groove B2, the first engaging portion 41 engages with the first engaged portion B21.

[0048] The overall shape and structure of the first engaging portion 41 are not particularly limited as long as the first engaging portion 41 can engage with the first engaged portion B21 and suppress the movement of the mounting member 3 and the clip 4 in the detachment direction D12. In the present embodiment, as shown in FIGS. 4 and 5, the first engaging portion 41 is formed as a convex portion that protrudes outward in the third direction D3 (the direction away from the second engaging portion 42). Although details will be described later, in the present embodiment, as shown in FIGS. 1, 4, and 5, when the mounting member 3 and the clip 4 are attached to the attachment groove B2 of the attachment target B, the first engaging portion 41 has a first inclined surface 41a that abuts against the opening edge E on the edge B1 side of the attachment groove B2. Further, in the present embodiment, the first engaging portion 41 has a first engaging surface 41b that engages with the first engaged portion B21 when a force is applied to the mounting member 3 and the clip 4 in the detachment direction D12. In the present embodiment, as shown in FIGS. 4 and 5, in the first engaging portion 41, the first inclined surface 41a is provided on the insertion direction D11 side, the first engaging surface 41b is provided on the detachment direction D12 side, and the first engaging portion 41 is formed as a convex portion having a substantially triangular shape.

[0049] As shown in FIG. 14, the first engaging surface 41b engages with the first engaged portion B21 of the attachment groove B2 to suppress the movement of the clip 4 - attached mounting member 3 in the detachment direction D12. The first engaging surface 41b is provided on the detachment direction D12 side of the first engaging portion 41. The first engaging surface 41b engages with the first engaged portion B21 provided to face the detachment direction D12 side of the first engaging surface 41b. More specifically, the first engaging surface 41b engages with the first engaging wall portion B211 provided on the detachment direction D12 side of the first engaged portion B21 in the detachment direction D12, thereby suppressing the first engaging portion 41 from disengaging from the first engaged portion B21. The inclination angle of the first engaging surface 41b is not limited to the illustrated inclination angle as long as the first engaging surface 41b can engage with the first engaged portion B21 and suppress the mounting member 3 and the clip 4 from detaching from the attachment groove B2 of the attachment target B.

[0050] The first inclined surface 41a is configured to abut against the opening edge E on the edge B1 side of the mounting groove B2 when the mounting member 3 to which the clip 4 is attached is inserted into the mounting groove B2. In a state where the first inclined surface 41a abuts against the opening edge E of the mounting groove B2, when the mounting member 3 is further pushed in the insertion direction D11 with respect to the mounting target B, the first inclined surface 41a is inclined so as to receive a reaction force causing the first engaging portion 41 to move toward the second engaging portion 42 in the third direction D3 from the opening edge E. Thereby, when the mounting member 3 to which the clip 4 is attached is inserted into the mounting groove B2, the mounting portion 43 is elastically deformed so that the first engaging portion 41 approaches the second engaging portion 42 by the reaction force received by the first inclined surface 41a from the opening edge E, and the clip 4 can move in the insertion direction D11 in the mounting groove B2. In the present embodiment, as shown in FIGS. 4 and 5, the first inclined surface 41a is inclined so as to approach the inside (the intermediate position between the first engaging portion 41 and the second engaging portion 42) in the third direction D3 as it advances in the insertion direction D11. The first inclined surface 41a is constituted by a flat surface in the present embodiment, but may be slightly curved.

[0051] The second engaging portion 42 engages with the second engaged portion B22 of the mounting groove B2 to suppress the movement of the mounting member 3 and the clip 4 in the detachment direction D12. As shown in FIGS. 4 and 5, the second engaging portion 42 is provided on the other end side of the mounting portion 43 in the circumferential direction of the mounting member 3. Further, as shown in FIGS. 1 and 4, the second engaging portion 42 is provided so as to project in the second direction D2 from the other end side of the mounting portion 43. Thereby, in a state where the clip 4 is attached to the mounting member 3, the second engaging portion 42 is disposed at a position corresponding to the position of the shaft portion 33a that enters the mounting groove B2 in the X-axis direction (see FIG. 3). Thereby, when the shaft portion 33a is disposed in the mounting groove B2, the second engaging portion 42 engages with the second engaged portion B22.

[0052] The overall shape and structure of the second engaging portion 42 are not particularly limited as long as the second engaging portion 42 can engage with the second engaged portion B22 and suppress the movement of the mounting member 3 and the clip 4 in the detachment direction D12. In the present embodiment, as shown in FIGS. 4 and 5, the second engaging portion 42 is formed as a convex portion that protrudes outward in the third direction D3 (the direction away from the first engaging portion 41). Although details will be described later, in the present embodiment, as shown in FIGS. 1, 4, and 5, when the mounting member 3 and the clip 4 are attached to the attachment groove B2 of the attachment target B, the second engaging portion 42 has a second inclined surface 42a that abuts against the opening edge E on the edge B1 side of the attachment groove B2. Further, in the present embodiment, the second engaging portion 42 has a second engaging surface 42b that engages with the second engaged portion B22 when a force is applied to the mounting member 3 and the clip 4 in the detachment direction D12. In the present embodiment, as shown in FIGS. 4 and 5, in the second engaging portion 42, the second inclined surface 42a is provided on the insertion direction D11 side, the second engaging surface 42b is provided on the detachment direction D12 side, and the second engaging portion 42 is formed as a substantially triangular convex portion.

[0053] As shown in FIG. 14, the second engaging surface 42b engages with the second engaged portion B22 of the attachment groove B2 to suppress the movement of the clip 4 - attached mounting member 3 in the detachment direction D12. The second engaging surface 42b is provided on the detachment direction D12 side of the second engaging portion 42. The second engaging surface 42b engages with the second engaged portion B22 provided to face the detachment direction D12 side of the second engaging surface 42b. More specifically, the second engaging surface 42b engages with the first engaging wall portion B221 provided on the detachment direction D12 side of the second engaged portion B22 in the detachment direction D12, thereby suppressing the second engaging portion 42 from disengaging from the second engaged portion B22. The inclination angle of the second engaging surface 42b is not limited to the illustrated inclination angle as long as it can engage with the second engaged portion B22 and suppress the detachment of the mounting member 3 and the clip 4 from the attachment groove B2 of the attachment target B.

[0054] The second inclined surface 42a is configured to abut against the opening edge E on the edge B1 side of the mounting groove B2 when the mounting member 3 to which the clip 4 is attached is inserted into the mounting groove B2. When the mounting member 3 is further pushed in the insertion direction D11 with respect to the mounting target B in a state where the second inclined surface 42a abuts against the opening edge E of the mounting groove B2, the second inclined surface 42a is inclined so as to receive a reaction force from the opening edge E in the third direction D3 causing the second engaging portion 42 to move toward the first engaging portion 41 side. Thereby, when the mounting member 3 to which the clip 4 is attached is inserted into the mounting groove B2, the mounting portion 43 is elastically deformed so that the second engaging portion 42 approaches the first engaging portion 41 side by the reaction force received by the second inclined surface 42a from the opening edge E, and the clip 4 can move in the insertion direction D11 in the mounting groove B2. In the present embodiment, as shown in FIGS. 4 and 5, the second inclined surface 42a is inclined so as to approach the inner side (the intermediate position between the first engaging portion 41 and the second engaging portion 42) in the third direction D3 as it advances in the insertion direction D11. The second inclined surface 42a is constituted by a flat surface in the present embodiment, but may be slightly curved.

[0055] As shown in FIGS. 4 and 5, the connecting portion 44 connects the first engaging portion 41 and the second engaging portion 42 which are separated in the circumferential direction of the mounting member 3. The connecting portion 44 is located on the detachment direction D12 side of the mounting member 3 in a state where the clip 4 is attached to the mounting member 3. The connecting portion 44 has elasticity that allows the first engaging portion 41 and the second engaging portion 42 to be separated from and approach each other. Therefore, when the first engaging portion 41 and the second engaging portion 42 approach each other with respect to the initial state, an urging force is applied in a direction in which the first engaging portion 41 and the second engaging portion 42 are separated from each other by the elasticity of the connecting portion 44, and when the first engaging portion 41 and the second engaging portion 42 are separated from each other with respect to the initial state, an urging force is applied in a direction in which the first engaging portion 41 and the second engaging portion 42 approach each other.

[0056] The shape and structure of the connecting portion 44 are not particularly limited as long as the first engaging portion 41 and the second engaging portion 42 have elasticity that allows them to move apart from and approach each other. In the present embodiment, as shown in FIGS. 4 and 5, the connecting portion 44 is bent in a zigzag shape. Specifically, the connecting portion 44 is configured as a bent plate shape and is provided so that the plate-shaped connecting portion 44 has folding portions on the insertion direction D11 side and the detachment direction D12 side.

[0057] In the present embodiment, as shown in FIGS. 4 and 5, the clip 4 has a first knob portion 45a and a second knob portion 45b. By operating the first knob portion 45a and the second knob portion 45b so as to approach each other in the third direction D3, the mounting portion 43 is elastically deformed so that the first engaging portion 41 and the second engaging portion 42 approach each other. Thereby, by operating the first knob portion 45a and the second knob portion 45b, the engagement between the first engaging portion 41 and the first engaged portion B21 and the engagement between the second engaging portion 42 and the second engaged portion B22 are released, and the mounting member 3 can be detached from the attachment target B. The shapes of the first knob portion 45a and the second knob portion 45b are not particularly limited as long as the mounting portion 43 can be elastically deformed so that the first engaging portion 41 and the second engaging portion 42 approach each other by operating them so as to approach each other. In the present embodiment, the first knob portion 45a and the second knob portion 45b are plate-shaped pieces that are continuously provided on the detachment direction D12 side of the first engaging portion 41 and the second engaging portion 42 and are continuous with the first engaging portion 41 and the second engaging portion 42.

[0058] As described above, the mounting portion 43 is attached to the mounted portion 31 so as to be relatively rotatable about the axis X of the attachment member 3. Thus, for example, even if the attachment member 3 rotates in the direction about the axis X due to torsion or the like of the long member 2, as shown in FIG. 14, the attachment member 3 rotates relative to the clip 4, so that the rotation of the attachment member 3 is suppressed from being transmitted to the clip 4. Therefore, the clip 4 rotates in conjunction with the rotation of the attachment member 3, so that the first engaging portion 41 of the clip 4 is prevented from disengaging from the first engaged portion B21 of the object to be attached B, or the second engaging portion 42 is prevented from disengaging from the second engaged portion B22. As a result, the engagement between the clip 4 and the object to be attached B is prevented from being released.

[0059] More specifically, for example, in FIG. 14, if the clip 4 rotates counterclockwise integrally with the attachment member 3, the first engaging portion 41 receives a force in the direction of being pressed against the first engaged portion B21 (that is, the left side in FIG. 14), while the second engaging portion 42 tends to move in the direction of coming out of the second engaged portion B22 (the left side in FIG. 14). Therefore, if the clip 4 engages with the attachment member 3 in the direction about the axis X and rotates together with the attachment member 3, one engaging portion of the clip 4 (the second engaging portion 42 in the above example) comes out of one engaged portion of the object to be attached B (the second engaged portion B22 in the above example). In the present embodiment, as shown by the two-dot chain line in FIG. 14, the attachment member 3 is configured to rotate relative to the clip 4, so that the rotation of the attachment member 3 about the axis X hardly affects the engagement between the first engaging portion 41 of the clip 4 and the first engaged portion B21 and the engagement between the second engaging portion 42 and the second engaged portion B22. Therefore, the engagement between the clip 4 and the object to be attached B is prevented from being released.

[0060] Also, in the present embodiment, as shown in FIGS. 3, 5, and 12, the mounting member 3 includes a projecting portion 34 that projects radially outward of the mounting member 3 with respect to the outer surface of the mounted portion 31 so that the mounting portion 43 of the clip 4 can be engaged in the second direction D2. Thereby, as shown in FIGS. 3 and 12, the projecting portion 34 engages with the mounting portion 43 in the second direction D2, suppressing the clip 4 from detaching from the mounting member 3 in the second direction D2. Therefore, even when a force is applied to the clip 4 in the direction in which the clip 4 comes off in the second direction D2 when the clip 4 is mounted on the mounting member 3 (for example, in the state of the long member assembly A), the mounting portion 43 of the clip 4 and the projecting portion 34 engage in the second direction D2, suppressing the detachment of the clip 4. Therefore, it is possible to suppress the clip 4 from being lost during conveyance, and there is no need to reassemble the detached clip 4.

[0061] As described above, when the mounting member 3 is rotatable relative to the clip 4 and has the projecting portion 34, even when an external force is applied to the long member 2, the clip 4 and the mounting member 3 are unlikely to come off from the mounting target B, and the clip 4 is unlikely to come off from the mounting member 3 during conveyance.

[0062] Also, in the present embodiment, as described above, the attachment member 3 has a rotation restricting portion RR that restricts the relative rotation of the attachment member 3 with respect to the clip 4 within a predetermined range between one end and the other end of the substantially U-shaped mounting portion 43, as shown in FIG. 14. In this case, excessive relative rotation of the attachment member 3 with respect to the clip 4 due to twisting or the like of the long member 2 can be suppressed. Specifically, as shown in FIG. 14, while the attachment member 3 is configured to be relatively rotatable with respect to the clip 4 by a predetermined amount, when the attachment member 3 attempts to rotate by more than a predetermined amount (beyond the allowable range), the rotation restricting portion RR and the clip 4 come into contact with each other, applying resistance to the rotation of the attachment member 3 and suppressing the rotation of the attachment member 3. As a result, the relative rotation of the attachment member 3 with respect to the clip 4 is restricted to a predetermined range. When the rotation of the attachment member 3 is restricted to a predetermined range, the long member 2 will not be twisted more than a predetermined amount. Therefore, for example, when the long member 2 is a control cable, damage to the outer casing and an unfavorable change in the stroke amount of the inner cable passing through the inside of the outer casing due to excessive twisting of the long member 2 are suppressed.

[0063] In the present embodiment, as shown in FIG. 14, the rotation restricting portion RR is provided so as to be spaced apart from the first knob portion 45a and the second knob portion 45b of the clip 4 in the direction around the axis X. When the attachment member 3 rotates by a predetermined amount in the direction around the axis X with respect to the clip 4, the rotation restricting portion RR is configured to contact either the first knob portion 45a or the second knob portion 45b.

[0064] Next, with reference to FIGS. 15 to 22, the first protruding portion PR1 and the second protruding portion PR2 provided on the clamping portion 33 will be described.

[0065] As shown in FIGS. 8, 15, and 17, the first protruding portion PR1 is a protruding portion that protrudes from the first opposing surface F1 to the second opposing surface F2 of the first wall body 33b. When the clamping portion 33 sandwiches the plate-shaped object to be attached B in the second direction D2, the first protruding portion PR1 contacts one surface of the plate-shaped object to be attached B, thereby suppressing the movement of the attachment member 3 in the detachment direction D12 away from the object to be attached B.

[0066] The first protrusion PR1 protrudes at a predetermined height toward the second facing surface F2 on the first facing surface F1. Specifically, as shown in FIG. 17, the first protrusion PR1 and the second protrusion PR2 are such that the length L1 in the second direction D2 between the top of the first protrusion PR1 (the portion farthest from the first facing surface F1 in the second direction D2) and the top of the second protrusion PR2 (the portion farthest from the second facing surface F2 in the second direction D2) is provided at a height shorter than the thickness (the thickness in the second direction D2) L2 of the plate-shaped object B to be attached. In this case, when the clamping portion 33 clamps the plate-shaped attachment member B in the second direction D2, the first protrusion PR1 is pressed by one surface of the object B to be attached and slightly deformed. On the other hand, the object B to be attached is pressed in the second direction D2 by the reaction force from the first protrusion PR1 that has been pressed and deformed. Therefore, the reaction force applied from the first protrusion PR1 to the object B to be attached suppresses the attachment member 3 from moving in the detachment direction D12 from the object B to be attached in the first direction D1.

[0067] In the present embodiment, the first protruding portion PR1 is provided at a height such that the length L3 (see FIG. 17) in the second direction D2 between the top portion of the first protruding portion PR1 (the flat surface FS to be described later in this embodiment) and the second opposing surface F2 is longer than the thickness L2 of the plate-shaped object B to be attached. In this case, when the object B to be attached is inserted between the first protruding portion PR1 and the second opposing surface F2, the insertion resistance is suppressed. Note that the first protruding portion PR1 may be provided at a height such that the length L3 in the second direction D2 between the top portion of the first protruding portion PR1 and the second opposing surface F2 is shorter than the thickness L2 of the plate-shaped object B to be attached. In this case, when the object B to be attached enters between the sandwiching portions 33, the object B to be attached is sandwiched in a state of being in contact with the first protruding portion PR1 and the second opposing surface F2. As will be described later, when the first protruding portion PR1 is displaced from the second protruding portion PR2 in the first direction D1, after the object B to be attached comes into contact with the first protruding portion PR1 and before it comes into contact with the second protruding portion PR2, the attachment member 3 can be moved relative to the object B to be attached with a small insertion force. Further, as in the present embodiment, when the length L3 in the second direction D2 between the top portion of the first protruding portion PR1 and the second opposing surface F2 is longer than the thickness L2 of the object B to be attached, and when the first protruding portion PR1 is displaced from the second protruding portion PR2 in the first direction D1, the attachment member 3 can be moved relative to the object B to be attached with an even smaller insertion force until it comes into contact with the second protruding portion PR2.

[0068] In the present embodiment, as shown in FIG. 15, a plurality of first protruding portions PR1 are provided spaced apart in the third direction D3 on the first opposing surface F1. Since a plurality of first protruding portions PR1 are provided, the attachment member 3 and the attachment target B come into contact with each other at a plurality of locations, so that the attachment member 3 is stably supported with respect to the attachment target B. Further, since the plurality of first protruding portions PR1 are arranged spaced apart in the third direction D3, both the first protruding portion PR1 on one side (the left side in FIG. 15) in the third direction D3 and the first protruding portion PR1 on the other side (the right side in FIG. 15) come into contact with the attachment target B. Therefore, rattling of the attachment member 3 with respect to the attachment target B is suppressed. In the present embodiment, as shown in FIG. 15, a shaft portion 33a inserted into the attachment groove B2 is located between the first protruding portion PR1 located on one side in the third direction D3 and the first protruding portion PR1 located on the other side. More specifically, the first protruding portion PR1 located on one side in the third direction D3 and the first protruding portion PR1 located on the other side are provided symmetrically with respect to a line extending in the first direction D1 passing through the axis X. In this way, when the first protruding portions PR1 are arranged spaced apart so as to sandwich the shaft portion 33a in the third direction D3, rattling of the attachment member 3, which is likely to rattle about the shaft portion 33a, is effectively suppressed.

[0069] In this embodiment, as shown in FIG. 15, a plurality of first protrusions PR1 are provided at intervals in the first direction D1 on the first opposing surface F1. Specifically, as shown in FIG. 15, the first protrusion PR1 includes a first insertion-side protrusion PR11 provided at intervals in the third direction D3 on the insertion direction D11 side with respect to the axis X of the long member 2, and a first detachment-side protrusion PR12 provided at intervals in the third direction D3 on the detachment direction D12 side in the first direction D1. In this case, when the attachment target B is clamped by the clamping portion 33, both the first insertion-side protrusion PR11 on the insertion direction D11 side and the first detachment-side protrusion PR12 on the detachment direction D12 side come into contact with the attachment target B. Therefore, rattling of the attachment member 3 with respect to the attachment target B is suppressed, and further detachment of the attachment member 3 from the attachment target B is suppressed. In this embodiment, the first insertion-side protrusion PR11 is provided on both sides in the insertion direction D11 side and the third direction D3 with respect to the axis X, and the first detachment-side protrusion PR12 is provided on both sides in the detachment direction D12 side and the third direction D3 with respect to the axis X. The first protrusion PR1 contacts the attachment target B at at least four locations around the axis X (shaft portion 33a) to support the attachment member 3. Therefore, rattling of the attachment member 3 hardly occurs, and detachment of the attachment member 3 from the attachment target B is suppressed.

[0070] In this embodiment, as shown in FIGS. 15, 22, etc., the first protrusion PR1 is formed in a block shape. Here, the block shape means that on the flat surface of the first opposing surface F1 (the region excluding the parts where other parts such as the shaft portion 33a are provided), the first protrusion PR1 is not provided over the entire first direction D1 or the third direction D3, but is provided with a predetermined length only in a part of the first direction D1 and the third direction D3, and protrudes in the second direction D2 toward the second opposing surface F2. The shape of the block-shaped first protrusion PR1 is not particularly limited. In this embodiment, the first protrusion PR1 is formed in a square shape when viewed in the second direction D2. However, for example, it may be circular when viewed in the second direction D2 (for example, the first protrusion PR1 is hemispherical or frustum-shaped). Note that the widths of the first protrusion PR1 in the first direction D1 and the third direction D3 are not particularly limited. For example, the (maximum) width L4 (see FIG. 15) of the first protrusion PR1 in the third direction D3 can be 2 times or less, preferably equal to or less than the (maximum) width L5 of the first protrusion PR1 in the first direction D1. Details will be described later, but in this case, the first protrusion PR1 does not become too long in the third direction D3. Therefore, when the mounting member 3 is inserted into the mounting groove B2, the first protrusion PR1 is easily deformed, and the mounting member 3 can be easily moved in the insertion direction D11 with respect to the mounting target B. The specific length of the width L4 of the first protrusion PR1 in the third direction D3 is not particularly limited, but for example, it can be 1 to 5 mm, preferably 1 to 2 mm. When the width L4 of the first protrusion PR1 in the third direction D3 is 1 mm or more, the detachment of the mounting member 3 from the mounting target B can be suppressed, and it is easy to secure the contact area between the first protrusion PR1 and the mounting target B. Also, when the width L4 of the first protrusion PR1 in the third direction D3 is 5 mm or less, preferably 2 mm or less, the first protrusion PR1 is easily deformed (easily crushed (see arrows A1 and A2 in FIG. 18)) on both sides of the detachment direction D12 side and the third direction D3, and the mounting member 3 can be easily moved in the insertion direction D11 with respect to the mounting target B. Note that the specific length of the width L5 of the first protrusion PR1 in the first direction D1 is not particularly limited, but for example, it can be 1 to 8 mm, preferably 1 to 3 mm. Also, the protrusion height L7 (see FIG. 17) of the plurality of first protrusions PR1 from the first opposing surface F1 is not particularly limited.Further, the protruding heights L7 of the plurality of first protruding portions PR1 may all be the same, or may be different from each other, for example, the height of the first insertion-side protruding portion PR11 and the first detachment-side protruding portion PR12 may be different from each other.

[0071] In the present embodiment, as shown in FIGS. 15 and 18, the first protruding portion PR1 is provided on the first opposing surface F1 such that a space allowing deformation in a direction including a component in the third direction D3 is formed on both sides of the first protruding portion PR1 in the third direction D3 when the first protruding portion PR1 comes into contact with and is pressed against one surface of the mounting target B. In this case, when the mounting member 3 is inserted into the mounting groove B2 and the first protruding portion PR1 comes into contact with and is pressed against one surface of the mounting target B (shown by a two-dot chain line in FIG. 18), as shown in FIG. 18, the first protruding portion PR1 can be deformed in the detachment direction D12 side in the first direction D1 (see arrow A1), and can also be deformed in a direction including a component in the third direction D3 on both sides in the third direction D3 (see arrow A2). Therefore, since the space allowing deformation in a direction including a component in the third direction D3 is formed on both sides of the first protruding portion PR1 in the third direction D3, the directions in which the first protruding portion PR1 can be deformed (the directions in which the crushed first protruding portion PR1 can move) become diverse. Thus, when the mounting member 3 is inserted into the mounting groove B2, the first protruding portion PR1 can be easily deformed, and the insertion force of the mounting member 3 can be reduced (for example, as shown in FIG. 19, when the first protruding portion is connected to the shaft portion 33a on one side in the third direction D3, and there is no space allowing deformation in a direction including a component in the third direction D3, the deformation of the first protruding portion in one side in the third direction D3 is inhibited. Also, since one side of the first protruding portion in the third direction D3 is connected to the shaft portion 33a, the deformation in the detachment direction D12 is also suppressed. Therefore, as shown in FIG. 19, when there is no space allowing deformation in a direction including a component in the third direction D3, a large insertion force is required when inserting the mounting member 3).

[0072] The space that allows deformation in the direction including the component of the third direction D3 means a space provided with a size such that when the first protruding portion PR1 receives a force from the mounting target B during insertion of the mounting member 3 into the mounting target B, it does not contact a wall or other member that inhibits deformation in the direction including the component of the third direction D3. Further, the direction including the component of the third direction D3 includes not only the third direction D3 but also the direction between the third direction D3 and the first direction D1. The size in the third direction D3 of the space provided on both sides in the third direction D3 of the first protruding portion PR1 is not particularly limited. For example, the size L6 (see FIG. 15) in the third direction D3 of the space provided in the third direction D3 of the first protruding portion PR1 (in this embodiment, the size of the narrower space among the spaces provided on both sides in the third direction D3) is preferably equal to or greater than the protruding height L7 (see FIG. 17) from the first opposing surface F1 of the first protruding portion PR1. In this case, even if the first protruding portion PR1 is crushed and greatly deformed, the first protruding portion PR1 does not contact other members or parts such as the shaft portion 33a and the deformation is not inhibited.

[0073] The structure of the first protruding portion PR1 is not particularly limited as long as a space that allows deformation in the direction including the component of the third direction D3 is formed on both sides of the first protruding portion PR1 in the third direction D3 when the first protruding portion PR1 contacts and is pressed against one surface of the mounting target B. In this embodiment, as shown in FIGS. 17 and 22, the first protruding portion PR1 has a flat surface FS provided substantially parallel to the first opposing surface F1 at the end on the second opposing surface F2 side in the second direction D2 (the topmost portion farthest from the first opposing surface F1 in the second direction D2). Further, in this embodiment, the first protruding portion PR1 has an inclined surface TS provided so as to connect to the flat surface FS on the insertion direction D11 side of the flat surface FS.

[0074] When the first protrusion PR1 has the flat surface FS, the frictional force between the flat surface FS and one surface of the object to be attached B increases due to the surface contact between the flat surface FS and one surface of the object to be attached B, making it more difficult for the attachment member 3 to detach from the object to be attached B. The inclined surface TS is inclined such that the height in the second direction D2 from the first opposing surface F1 decreases as it goes in the insertion direction D11. By providing the inclined surface TS, when attaching the attachment member 3 to the object to be attached B, the attachment member 3 can be easily moved in the insertion direction D11 with respect to the object to be attached B.

[0075] The shape of the first protrusion PR1 is not particularly limited as long as a space that allows deformation in a direction including a component in the third direction D3 is formed on both sides of the first protrusion PR1 in the third direction D3 when the first protrusion PR1 contacts and is pressed against one surface of the object to be attached B. In the present embodiment, the first protrusion PR1 is formed in a substantially rectangular shape when viewed in the second direction D2 (see FIG. 15) and in a substantially trapezoidal shape when viewed in the third direction D3 (see FIG. 17).

[0076] Next, the second protrusion PR2 will be described. Note that the configuration of the second protrusion PR2 can be the same as the configuration of the first protrusion PR1, and the matters described for the first protrusion PR1 can also be applied to the second protrusion PR2. However, the configuration of the second protrusion PR2 may be different from the configuration of the first protrusion PR1.

[0077] As shown in FIGS. 8, 16, and 17, the second protrusion PR2 is a protrusion that protrudes from the second opposing surface F2 of the second wall body 33c toward the first opposing surface F1. The second protrusion PR2 suppresses the movement of the attachment member 3 in the detachment direction D12 in which the attachment member 3 detaches from the object to be attached B by contacting the other surface of the plate-shaped object to be attached B when the sandwiching portion 33 sandwiches the plate-shaped object to be attached B in the second direction D2.

[0078] The second protrusion PR2 protrudes at a predetermined height toward the first opposing surface F1 on the second opposing surface F2. As described above, the first protrusion PR1 and the second protrusion PR2 are provided at a height such that the length L1 in the second direction D2 between the top of the first protrusion PR1 and the top of the second protrusion PR2 is shorter than the thickness L2 of the plate-shaped object B to be attached. In this case, when the sandwiching portion 33 sandwiches the plate-shaped attachment member B in the second direction D2, the second protrusion PR2 is pressed by the other surface of the attachment object B and slightly deformed. On the other hand, the attachment object B is pressed in the second direction D2 by the reaction force from the second protrusion PR2 that has been pressed and deformed. Therefore, the reaction force applied from the second protrusion PR2 to the attachment object B suppresses the attachment member 3 from moving in the separation direction D12 in the first direction D1 from the attachment object B.

[0079] In the present embodiment, the second protrusion PR2 is provided at a height such that the length L8 (see FIG. 17) in the second direction D2 between the top of the second protrusion PR2 (the flat surface FS described later in this embodiment) and the first opposing surface F1 is longer than the thickness L2 of the plate-shaped object B to be attached.

[0080] In this embodiment, as shown in FIG. 16, a plurality of second protruding portions PR2 are provided at intervals in the third direction D3 on the second opposing surface F2. Since a plurality of second protruding portions PR2 are provided, the mounting member 3 and the mounting target B come into contact with each other at a plurality of locations, so that the mounting member 3 is stably supported with respect to the mounting target B. Further, since the plurality of second protruding portions PR2 are arranged at intervals in the third direction D3, both the second protruding portion PR2 on one side (the left side in FIG. 16) in the third direction D3 and the second protruding portion PR2 on the other side (the right side in FIG. 16) come into contact with the mounting target B. Therefore, rattling of the mounting member 3 with respect to the mounting target B is suppressed. In this embodiment, as shown in FIG. 16, a shaft portion 33a inserted into the mounting groove B2 is located between the second protruding portion PR2 located on one side in the third direction D3 and the second protruding portion PR2 located on the other side. More specifically, the second protruding portion PR2 located on one side in the third direction D3 and the second protruding portion PR2 located on the other side are provided symmetrically with respect to a line extending in the first direction D1 passing through the axis X. Thus, when the second protruding portions PR2 are arranged at intervals so as to sandwich the shaft portion 33a in the third direction D3, rattling of the mounting member 3, which is likely to rattle about the shaft portion 33a, is effectively suppressed.

[0081] In this embodiment, as shown in FIG. 16, a plurality of second protrusions PR2 are provided at intervals in the first direction D1 on the second opposing surface F2. Specifically, as shown in FIG. 16, the second protrusion PR2 includes a second insertion-side protrusion PR21 provided at intervals in the third direction D3 on the insertion direction D11 side with respect to the axis X of the long member 2, and a second detachment-side protrusion PR22 provided at intervals in the third direction D3 on the detachment direction D12 side in the first direction D1. In this case, both the second insertion-side protrusion PR21 on the insertion direction D11 side and the second detachment-side protrusion PR22 on the detachment direction D12 side come into contact with the attachment target B. Therefore, rattling of the attachment member 3 with respect to the attachment target B is suppressed, and detachment of the attachment member 3 from the attachment target B is further suppressed. In this embodiment, the second insertion-side protrusion PR21 is provided on both sides in the third direction D3 on the insertion direction D11 side with respect to the axis X, and the second detachment-side protrusion PR22 is provided on both sides in the third direction D3 on the detachment direction D12 side with respect to the axis X. The second protrusion PR2 contacts the attachment target B at at least four locations around the axis X (shaft portion 33a) to support the attachment member 3. Therefore, rattling of the attachment member 3 hardly occurs, and detachment of the attachment member 3 from the attachment target B is suppressed.

[0082] In this embodiment, the second protruding portion PR2 is formed in a block shape, similar to the first protruding portion PR1. Here, the block shape means that on the flat surface of the second opposing surface F2 (the region excluding the portions where other parts such as the shaft portion 33a are provided), the second protruding portion PR2 is not provided across the entire first direction D1 or the third direction D3, but is provided only in a part of the first direction D1 and the third direction D3 with a predetermined length and protrudes in the second direction D2 toward the first opposing surface F1. The shape of the block-shaped second protruding portion PR2 is not particularly limited. In this embodiment, the second protruding portion PR2 is formed in a square shape when viewed in the second direction D2. However, for example, it may be circular when viewed in the second direction D2 (for example, the second protruding portion PR2 is hemispherical or frustoconical), as long as it has a height L10 protruding from the second opposing surface F2. Note that the widths of the second protruding portion PR2 in the first direction D1 and the third direction D3 are not particularly limited. In this embodiment, the width of the second protruding portion PR2 in the first direction D1 and the width in the third direction D3 are the same as the width L5 of the first protruding portion PR1 in the first direction D1 and the width L4 in the third direction D3, respectively. In this case, the pressing force from the first protruding portion PR1 to one surface of the attachment target B and the pressing force from the second protruding portion PR2 toward the other surface of the attachment target B become substantially uniform. Note that the width of the second protruding portion PR2 in the first direction D1 may be different from the width L5 of the first protruding portion PR1 in the first direction D1, and the width of the second protruding portion PR2 in the third direction D3 may be different from the width L4 of the first protruding portion PR1 in the third direction D3. Also, the protruding height L10 (see FIG. 17) of the second protruding portion PR2 from the second opposing surface F2 of the plurality of second protruding portions PR2 is not particularly limited. Also, the protruding heights L10 of the plurality of second protruding portions PR2 may all be the same, or may be different from each other, for example, the second insertion-side protruding portion PR21 and the second detachment-side protruding portion PR22 may have different heights from each other. Also, the protruding height L10 of the second protruding portion PR2 may be different from the protruding height L7 of the first protruding portion PR1.

[0083] In this embodiment, as shown in FIG. 16, the second protruding portion PR2 is provided on the second opposing surface F2 such that spaces allowing deformation in a direction including a component in the third direction D3 are formed on both sides of the second protruding portion PR2 in the third direction D3 when the second protruding portion PR2 comes into contact with and is pressed against the other surface of the object B to be attached. In this case, when the attachment member 3 is inserted into the attachment groove B2 and the second protruding portion PR2 comes into contact with and is pressed against the other surface of the object B to be attached, the second protruding portion PR2, like the first protruding portion PR1, can be deformed in the first direction D1 toward the detachment direction D12 side and can also be deformed in a direction including a component in the third direction D3 (see FIG. 18 which explains the first protruding portion PR1). Therefore, since the spaces allowing deformation in a direction including a component in the third direction D3 are formed on both sides of the second protruding portion PR2 in the third direction D3, the directions in which the second protruding portion PR2 can be deformed (the directions in which the crushed second protruding portion PR2 can move) become diverse. Thus, when the attachment member 3 is inserted into the attachment groove B2, the second protruding portion PR2 can be easily deformed, and the insertion force of the attachment member 3 can be reduced.

[0084] Note that the space allowing deformation in a direction including a component in the third direction D3 refers to a space provided with a size such that when the second protruding portion PR2 receives a force from the object B to be attached during insertion of the attachment member 3, it does not come into contact with a wall or other member that inhibits deformation in a direction including a component in the third direction D3. The size of the space provided on both sides of the second protruding portion PR2 in the third direction D3 is not particularly limited. For example, the size L9 (see FIG. 16) of the space provided in the third direction D3 of the second protruding portion PR2 (in this embodiment, the size of the narrower space of the spaces provided on both sides in the third direction D3) is preferably equal to or greater than the protruding height L10 (see FIG. 17) from the second opposing surface F2 of the second protruding portion PR2. In this case, even if the second protruding portion PR2 is crushed and greatly deformed, the second protruding portion PR2 does not come into contact with other members or parts such as the shaft portion 33a and the deformation is not inhibited.

[0085] The structure of the second protrusion PR2 is not particularly limited as long as a space allowing deformation in a direction including a component in the third direction D3 is formed on both sides of the second protrusion PR2 in the third direction D3 when the second protrusion PR2 comes into contact with and is pressed against the other surface of the object B to be attached. In the present embodiment, as shown in FIG. 17, the second protrusion PR2 has a flat surface FS provided substantially parallel to the second opposing surface F2 at an end portion on the first opposing surface F1 side in the second direction D2 (the top portion farthest from the second opposing surface F2 in the second direction D2). Further, in the present embodiment, the second protrusion PR2 has an inclined surface TS provided so as to connect to the flat surface FS on the insertion direction D11 side of the flat surface FS.

[0086] When the second protrusion PR2 has the flat surface FS, the frictional force between the flat surface FS and the other surface of the object B to be attached increases due to the surface contact between the flat surface FS and the other surface of the object B to be attached, and it becomes more difficult for the attachment member 3 to separate from the object B to be attached. The inclined surface TS is inclined such that the height in the second direction D2 from the second opposing surface F2 decreases as it goes in the insertion direction D11. By providing the inclined surface TS, when attaching the attachment member 3 to the object B to be attached, it can be easily moved in the insertion direction D11.

[0087] The shape of the second protrusion PR2 is not particularly limited as long as a space allowing deformation in a direction including a component in the third direction D3 is formed on both sides of the second protrusion PR2 in the third direction D3 when the second protrusion PR2 comes into contact with and is pressed against the other surface of the object B to be attached. In the present embodiment, the second protrusion PR2 is formed in a substantially rectangular shape when viewed in the second direction D2 (see FIG. 16) and is formed in a substantially trapezoidal shape when viewed in the third direction D3 (see FIG. 17).

[0088] In the present embodiment, as shown in FIGS. 17 and 20 (in FIG. 20, the second insertion-side protrusion PR21 and the second detachment-side protrusion PR22 are shown by a two-dot chain line), the first insertion-side protrusion PR11 is displaced in the first direction D1 with respect to the second insertion-side protrusion PR21. In this case, in the process of inserting the attachment member 3 into the attachment groove B2 of the attachment target B, after either one of the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21 becomes capable of contacting the attachment target B (opposing the attachment target B in the second direction D2), it contacts the other of the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21. Therefore, first, with only one of the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21 being capable of contacting the attachment target B (opposing the attachment target B in the second direction D2), the attachment member 3 relatively moves in the first direction D1 with respect to the attachment target B in a state with little resistance. Thereafter, both the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21 come into contact with the attachment target B, and the attachment member 3 relatively moves in the first direction D1 with respect to the attachment target B. Therefore, since the resistance during insertion of the attachment member 3 into the attachment target B increases stepwise, the resistance during insertion does not increase rapidly, and the attachment member 3 can be easily inserted into the attachment target B. Note that the state in which only one of the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21 can contact the attachment target B may be a state in which the attachment target B and one of the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21 are actually in contact, or may be a state in which the attachment target B and one of the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21 are opposing each other but not in contact.

[0089] More specifically, in FIG. 20, regarding the relative positions Ba, Bb, Bc, and Bd between the attachment target B shown by the two-dot chain line and the attachment member 3, taking the attachment start position as the relative position Ba, an example of a position where only the first insertion-side protrusion PR11 can come into contact with one surface of the attachment target B (opposite to one surface of the attachment target B) is the relative position Bb, an example of a position where one surface of the attachment target B comes into contact with both the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21 is the relative position Bc, and taking the attachment completion position as the relative position Bd, when the attachment member 3 is inserted into the attachment target B until the relative position between the attachment target B and the attachment member 3 moves from the relative position Ba to the relative position Bd, first, only the first insertion-side protrusion PR11 can come into contact with one surface of the attachment target B (opposite to one surface of the attachment target B), and a state occurs where the second insertion-side protrusion PR21 is not in contact with the attachment target B. At the relative position Bb where only the first insertion-side protrusion PR11 can come into contact with one surface of the attachment target B (opposite to one surface of the attachment target B) and the second insertion-side protrusion PR21 is not in contact with the attachment target B, the resistance between the attachment member 3 and the attachment target B is small (either there is no resistance or only the frictional resistance between the first insertion-side protrusion PR11 and the attachment target B). Therefore, at the initial stage of inserting the attachment member 3 into the attachment target B, it becomes smaller than the frictional resistance when both the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21 come into contact with the attachment target B. After that, when the attachment member 3 is further inserted into the attachment target B and the attachment member 3 reaches the relative position Bc from the relative position Bb, one surface of the attachment target B comes into contact with both the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21, and the insertion resistance slightly increases. Also, when the attachment member 3 reaches the relative position Bd from the relative position Bc, the attachment target B comes into contact with the first detachment-side protrusion PR12 and the second detachment-side protrusion PR22 in addition to the first insertion-side protrusion PR11 and the second insertion-side protrusion PR21, and the insertion resistance of the attachment member 3 further increases. Thus, as the relative position changes from Ba to Bd, the insertion resistance of the attachment member 3 gradually increases. As described above, in this embodiment, the insertion resistance at the initial stage of inserting the attachment member 3 into the attachment target B is small.In addition, in the present embodiment, the insertion resistance of the mounting member 3 gradually increases, and the insertion force of the mounting member 3 increases step by step without a sharp increase. Therefore, the mounting member 3 can be easily inserted. In particular, in the present embodiment, spaces that allow deformation in a direction including a component in the third direction D3 are formed on both sides in the third direction D3 of the first insertion-side protrusion PR11, the second insertion-side protrusion PR21, the first detachment-side protrusion PR12, and the second detachment-side protrusion PR22. Therefore, the first protrusion PR1 and the second protrusion PR2 are easily deformed, and the required insertion force increases step by step. Therefore, the mounting member 3 can be easily inserted into the mounting groove B2 of the mounting target B with a small insertion force.

[0090] In the present embodiment, the first insertion-side protrusion PR11 is located on the insertion direction D11 side with respect to the second insertion-side protrusion PR21. However, the second insertion-side protrusion PR21 may be located on the insertion direction D11 side with respect to the first insertion-side protrusion PR11. Further, in the present embodiment, as shown in FIGS. 17 and 20, the arrangement region of the first insertion-side protrusion PR11 in the first direction D1 is provided so as not to overlap the arrangement region of the second insertion-side protrusion PR21 in the first direction D1. However, the arrangement region of the first insertion-side protrusion PR11 in the first direction D1 may overlap the arrangement region of the second insertion-side protrusion PR21 in the first direction D1.

[0091] In the present embodiment, the first insertion-side protrusion PR11 is arranged offset in the third direction D3 with respect to the second insertion-side protrusion PR21. In this case, when the mounting member 3 is attached to the mounting target B, rattling of the mounting member 3 with respect to the mounting target B is suppressed. Further, in the present embodiment, the separation distance in the third direction D3 between the pair of first insertion-side protrusions PR11 is smaller than the separation distance in the third direction D3 between the pair of second insertion-side protrusions PR21. Note that the first insertion-side protrusion PR11 may be provided at the same position as the second insertion-side protrusion PR21 in the third direction D3.

[0092] Further, in the present embodiment, the first detachment-side protrusion PR12 is displaced in the third direction D3 with respect to the second detachment-side protrusion PR22. In this case, when the attachment member 3 is attached to the attachment target B, rattling of the attachment member 3 with respect to the attachment target B is suppressed. Also, in the present embodiment, the separation distance in the third direction D3 between the pair of first detachment-side protrusions PR12 is smaller than the separation distance in the third direction D3 between the pair of second detachment-side protrusions PR22. Note that the first detachment-side protrusion PR12 may be provided at the same position as the second detachment-side protrusion PR22 in the third direction D3.

[0093] Note that, in the present embodiment, as shown in FIG. 20, the first detachment-side protrusion PR12 is arranged at the same position as the second detachment-side protrusion PR22 in the first direction D1. However, as shown in FIG. 21, the first insertion-side protrusion PR11 may be displaced in the first direction D1 with respect to the second insertion-side protrusion PR21, and the first detachment-side protrusion PR12 may be displaced in the first direction D1 with respect to the second detachment-side protrusion PR22. In this case, as the relative position changes from the relative position Ba shown in FIG. 20 to the relative position Bd, the insertion resistance of the attachment member 3 gradually increases in more stages than in the embodiment shown in FIG. 20. Therefore, the insertion of the attachment member 3 becomes even easier.

[0094] Note that, although not particularly shown, the first insertion-side protrusion PR11 may be located at the same position as the second insertion-side protrusion PR21 in the first direction D1, and the first detachment-side protrusion PR12 may be displaced in the first direction D1 with respect to the second detachment-side protrusion PR22.

[0095] Next, an example of the attachment process of the attachment member 3 to the attachment target B shown as a bracket (hereinafter referred to as bracket B) will be described. Note that the attachment process described below is merely an example, and the present invention is not limited by the following description.

[0096] First, as shown in FIGS. 2 and 10(A) to 11(B), a clip 4 is attached to an attachment member 3 to which a long member 2 is connected. For example, as shown in FIG. 2, the clip 4 is moved in the second direction D2 (axis X direction) from one end side in the second direction D2 of the attachment member 3 (in this embodiment, the second connection portion 322 side) to attach the clip 4 to the attachment member 3. Specifically, as shown in FIGS. 10(A) to 11(B), a part of the clip 4 in the direction around the axis X (the right side portion of the mounting portion 43 in FIGS. 10(B) and 11(B)) is engaged with the protruding portion 34. Next, in order to engage the side of the clip 4 opposite to the side engaged with the protruding portion 34 with the protruding portion 34, it is pushed toward the protruding portion 34.

[0097] When the clip 4 is pushed toward the protruding portion 34, since the second wall body 33c of the attachment member 3 has a chamfered portion CH, the clip 4 contacts the chamfered portion CH when the clip 4 is pushed in. When the clip 4 is pushed in while in contact with the chamfered portion CH, the clip 4 elastically deforms so as to expand outward, and the clip 4 can be easily engaged with the protruding portion 34. As a result, as shown in FIGS. 3 and 6, the mounting portion 43 of the clip 4 is attached to the mounted portion 31 of the attachment member 3, and the clip 4 is attached to the attachment member 3.

[0098] When the clip 4 is connected to the attachment member 3, as shown in FIGS. 3 and 13, the attachment member 3 (long member assembly A) is attached to the attachment groove B2 of the bracket B. Specifically, the attachment member 3 is attached to the bracket B by moving the attachment member 3 in the insertion direction D11 with respect to the attachment groove B2 of the bracket B, or by moving the bracket B with respect to the attachment member 3.

[0099] At this time, as shown in FIG. 3, the mounting member 3 and the bracket B are arranged such that the clamping portion 33 (shaft portion 33a) of the mounting member 3 is located at the position of the mounting groove B2 of the bracket B, and the mounting member 3 is inserted into the mounting groove B2 of the bracket B. Thereby, the shaft portion 33a of the mounting member 3 enters from the insertion portion B23 of the mounting groove B2 toward the installation portion B24 (see FIG. 1).

[0100] When the mounting member 3 is pushed in as it is in the insertion direction D11, the first inclined surface 41a of the first engaging portion 41 and the second inclined surface 42a of the second engaging portion 42 abut against the opening edge E of the mounting groove B2. When the mounting member 3 is pushed in the insertion direction D11 with the first inclined surface 41a and the second inclined surface 42a abutting against the opening edge E of the mounting groove B2, the mounting portion 43 is elastically deformed so that the first engaging portion 41 and the second engaging portion 42 approach each other by the reaction force applied from the opening edge E to the first inclined surface 41a and the second inclined surface 42a. As a result, as shown in FIG. 14, the first engaging portion 41 and the second engaging portion 42 are respectively engaged with the first engaged portion B21 and the second engaged portion B22, and the attachment of the mounting member 3 to the bracket B is completed.

[0101] In the process of inserting the mounting member 3, the first insertion-side protrusion PR11 contacts one surface of the bracket B. As described above, the first insertion-side protrusion PR11 can be deformed in the first direction D1 toward the detachment direction D12 side (see the arrow A1 in FIG. 18), and can also be deformed in a direction including a component in the third direction D3 (see the arrow A2 in FIG. 18). Therefore, when the mounting member 3 is inserted into the mounting groove B2, the first insertion-side protrusion PR11 is easily deformed by the reaction force from one surface of the bracket B, and the mounting member 3 can be easily inserted even with a low insertion force. Further, in the present embodiment, the width of the first insertion-side protrusion PR11 in the third direction D3 is 1 to 5 mm, preferably 1 to 2 mm, and the volume of the first insertion-side protrusion PR11 that needs to be crushed when inserting the mounting member 3 is smaller than that of a rail-shaped convex portion that is long in the third direction D3 as shown in FIG. 19. Therefore, the mounting member 3 can be easily inserted.

[0102] In FIG. 20, when the mounting member 3 reaches from the relative position Ba to the relative position Bb and further moves in the insertion direction D11 from the state where only the first insertion-side protrusion PR11 is deformed, the second insertion-side protrusion PR21 contacts the other surface of the bracket B and deforms (see the relative position Bc in FIG. 20). Thereafter, when the mounting member 3 is further inserted, the first detachment-side protrusion PR12 and the second detachment-side protrusion PR22 contact and deform the one surface and the other surface of the bracket B, respectively (see the relative position Bd in FIG. 20). In the present embodiment, as described above, the first protrusion PR1 and the second protrusion PR2 are easily deformed, and the insertion force of the mounting member 3 increases stepwise. Therefore, the mounting member 3 can be easily inserted with a small insertion force. When the mounting member 3 is attached to the attachment target B, the movement of the mounting member 3 in the second direction D2 is suppressed by the clamping portion 33, and the movement of the mounting member 3 in the detachment direction D12 with respect to the attachment target B is suppressed by the first protrusion PR1 and the second protrusion PR2.

[0103] In the above-described attached state, when a force in the detachment direction D12 is applied to the mounting member 3, the force in the detachment direction D12 is transmitted from the mounting member 3 to the clip 4. Since the first engaging portion 41 and the second engaging portion 42 of the clip 4 are respectively engaged with the first engaged portion B21 and the second engaged portion B22, the movement of the clip 4 in the detachment direction D12 is suppressed. As a result, the movement of the mounting member 3 to which the clip 4 is attached in the detachment direction D12 is also suppressed.

[0104] In addition, when a torsional force is applied to the long member 2 due to vibrations of the object to be attached or interference with other members, the attachment member 3 to which the long member 2 is attached rotates in the direction around the axis X as shown by the two-dot chain line in FIG. 14. In the present embodiment, even when the attachment member 3 rotates around the axis X, the attachment member 3 is configured to rotate relative to the clip 4. Therefore, when the amount of rotation of the attachment member 3 is within a predetermined range, no rotational force is transmitted to the clip 4, and the clip 4 does not rotate around the axis X. Accordingly, the first engaging portion 41 of the clip 4 does not move in a direction away from the first engaged portion B21, and the second engaging portion 42 does not move in a direction away from the second engaged portion B22. Thereby, it is possible to suppress the release of the engagement between the clip 4 and the bracket B.

[0105] Further, when the attachment member 3 rotates beyond a predetermined amount due to torsion or the like of the long member 2, the rotation restricting portion RR of the attachment member 3 contacts the first knob portion 45a or the second knob portion 45b as shown by the two-dot chain line in FIG. 14. In this case, when the rotation restricting portion RR contacts the first knob portion 45a or the second knob portion 45b, a resistance in the direction opposite to the rotation direction is applied to the attachment member 3, and the rotation of the attachment member 3 is suppressed. Thereby, excessive relative rotation of the attachment member 3 with respect to the clip 4 is suppressed.
