Abstract
Description
Technical Field
[0001] The present invention relates to a holder for a long member for holding a linear, tubular or rod-shaped long member.
Background Art
[0002] For example, in an automobile, pipes, tubes, wires, cables, harnesses, etc. are used, but these may cause inconveniences such as entanglement, interference with other members, damage, etc.; therefore, usually, they are housed and held in some kind of holder and are often disposed at a predetermined position inside the vehicle through the holder.
[0003] For example, Patent Document 1 below describes a holder that is fixed to a fixed member having a protruding fixed portion through the fixed portion and holds a long member.
[0004] This holder for a long member includes a holding member having a holding portion for holding the long member and a frame-shaped main body portion to which the holding portion is connected, a vibration-proof member having a frame-shaped portion inserted inside the frame-shaped main body portion and a pedestal portion that abuts against the fixed member, and an insertion portion that is inserted inside the frame-shaped portion and receives the fixed portion, and a fixing member that is fixed to the fixed portion.
[0005] Further, the fixing member has a flange portion on the other end side, and the vibration-proof member has an extension piece extending from the side of the frame-shaped portion opposite to the pedestal portion side, and this extension piece is pressed by the flange portion and can be bent outward. Further, as shown in FIG. 10 of Patent Document 1, the extension piece is sandwiched between the flange portion and the upper end surface of the frame-shaped main body portion.

Summary of the Invention
Problems to be Solved by the Invention
[0007] Incidentally, when a long member is held with a holder such as the one described in Patent Document 1 above, the long member is generally held approximately parallel to or at a predetermined angle to the surface of the member to be fixed.
[0008] However, if a twisting force is applied to the long member, that is, a force that moves the long member closer to or away from the fixed surface of the fixed member, the flange portion of the fixed member and the upper end surface of the frame-shaped main body may come into contact with each other and interfere. In this case, for example, vibrations generated from the long member may be transmitted to the fixed member via the frame-shaped main body, and since the vibration-damping member does not intervene, the vibration-damping performance of the vibration-damping member cannot be fully demonstrated.
[0009] Therefore, the object of the present invention is to provide a holder for a long member that makes it difficult for the holding member and the fixing member to interfere with each other even when a twisting force is applied to the long member, thereby allowing the vibration damping performance of the vibration damping member to be fully exhibited. [Means for solving the problem]
[0010] To achieve the above objective, the present invention provides a holder that is fixed to a fixed member having a shaft member via the shaft member and holds a long member, comprising: a holder member having a frame-shaped main body to which a holding portion for holding the long member is connected; a vibration-damping member made of an elastic material and having a frame-shaped portion inserted inside the frame-shaped main body; and a fixing member having an insertion portion inserted inside the frame-shaped portion and receiving the shaft member, a locking portion provided inside the insertion portion for locking onto the shaft member, and a flange portion protruding from one end of the insertion portion, wherein the vibration-damping member The insert has a pair of extension pieces that protrude from the frame-shaped main body when the frame-shaped main body is inserted inside the frame-shaped main body, and that are sandwiched between the frame-shaped main body and the flange when the insert is inserted inside the frame-shaped main body, and is characterized in that, when viewed from the insertion direction of the insert, a clearance is provided between the inner surface of the side wall of the frame-shaped main body, which is positioned opposite to the wall of the frame-shaped main body where the pair of extension pieces of the vibration-damping member are not provided, and the outer edge of the flange, which is positioned opposite to the side wall of the frame-shaped main body. [Effects of the Invention]
[0011] In the present invention, since a pair of extension pieces are sandwiched between the frame-shaped main body and the flange portion, when a twisting force is applied to the long member held by the holding portion of the holding member, it is possible to make it difficult for the frame-shaped main body to interfere with the flange portion. Furthermore, since a clearance is provided between the inner surface of the side wall portion of the frame-shaped main body, which is positioned opposite to the wall portion of the frame-shaped main body from which the pair of extension pieces of the vibration-damping member do not extend, and the outer edge portion of the flange portion, which is positioned opposite to the side wall portion of the frame-shaped main body, in this case as well, when a twisting force is applied to the long member, it is possible to make it difficult for the frame-shaped main body to interfere with the flange portion.
[0012] As described above, in this invention, the frame-shaped main body can be made less likely to interfere with the flange portion in both the area where the pair of extension pieces of the vibration-damping member are provided and the area where the pair of extension pieces are not provided. As a result, it is possible to make it less likely for vibration transmission paths that do not go through the vibration-damping member to occur in the holder, so that the vibration-damping performance of the vibration-damping member can be fully demonstrated.

Embodiments for Carrying Out the Invention
[0014] (An Embodiment of a Fixture for a Long Member) Hereinafter, an embodiment of a fixture for a long member according to the present invention will be described with reference to the drawings.
[0015] As shown in FIG. 14, the fixture 10 for a long member of this embodiment (hereinafter, also simply referred to as "fixture 10") is fixed to the fixed member 1 having the shaft member 5 via the shaft member 5 and holds the long member P (see FIG. 12).
[0016] As shown in FIG. 14, in this embodiment, the shaft member 5 protrudes from the fixed surface 3 of the fixed member 1 (which is one side in the thickness direction of the fixed member 1 and means the surface on the side where the fixture is arranged), such as a vehicle body panel or a vehicle body frame.
[0017] Examples of the shaft member 5 include a so-called stud bolt that stands upright integrally or separately from the fixed surface 3 and has a thread groove on its outer peripheral surface. In addition, the shaft member 5 in this embodiment has its axial direction (the direction along the axis C1 of the shaft member 5 shown in FIG. 14) perpendicular to the surface direction of the fixed surface 3. Note that the shaft member 5 is not limited to a stud bolt, and may be, for example, a columnar member having a prismatic or cylindrical shape, as long as the fixing means of the fixing member 80 (which will be described later) can be engaged.
[0018] In addition, the long member P is, for example, a linear, tubular or rod-shaped member such as a pipe, a tube, a hose, a rod, a wire, a cable, a harness, or a cord.
[0019] As shown in Figure 1, the holder 10 is mainly composed of a holding member 20 having a holding portion 21 and a frame-shaped main body portion 30, a vibration-damping member 50 having a frame-shaped portion 51, and a fixing member 80 provided with an insertion portion 81, a locking portion 94, and a flange portion 95.
[0020] Then, the frame-shaped part 51 is inserted inside the frame-shaped main body part 30, and the insertion part 81 is inserted inside the frame-shaped part 51, so that the vibration-damping member 50 and the fixing member 80 are assembled to the holding member 20, as shown in Figures 14 to 17.
[0021] In the following explanation, the insertion direction of the insertion part 81 into the inside of the frame-shaped main body part 30, as shown by arrow F1 in Figure 1, will also be referred to as the "frame-shaped part insertion direction F1," and the insertion direction of the insertion part 81 into the inside of the frame-shaped part 51, as shown by arrow F2 in Figure 1, will also be referred to as the "insertion part insertion direction F2."
[0022] Furthermore, the state in which the vibration-damping member 50 and the fixing member 80 are assembled to the holding member 20 means that the frame-shaped portion 51 is inserted into the frame-shaped main body portion 30 to its maximum insertion position, and the insertion portion 81 is inserted into the frame-shaped portion 51 to its maximum insertion position.
[0023] Furthermore, as shown in Figure 15, the frame-shaped main body portion 30 of the holding member 20 is provided with a second engaging portion 45, and the frame-shaped portion 51 of the vibration-damping member 50 is provided with a third engaging portion 69. Then, as shown by arrow F1 in Figure 1, when the frame-shaped portion 51 is inserted into the inside of the frame-shaped main body portion 30 from the side of the member to be fixed 1, the second engaging portion 45 and the third engaging portion 69 become able to engage with each other, as shown in Figure 15, and the vibration-damping member 50 is assembled to the holding member 20.
[0024] Furthermore, as shown in Figure 16, the frame-shaped main body portion 30 of the holding member 20 is provided with a first engaging portion 43, and the insertion portion 81 of the fixing member 80 is provided with a fifth engaging portion 91. In addition, the frame-shaped portion 51 of the vibration-damping member 50 is provided with a fourth engaging portion 75, and the insertion portion 81 of the fixing member 80 is provided with a sixth engaging portion 93.
[0025] Then, as shown by arrow F2 in Figure 1, when the insertion part 81 is inserted into the inside of the frame-shaped part 51 from the side opposite to the member to be fixed 1, as shown in Figure 16, the first engaging part 43 and the fifth engaging part 91 are positioned opposite each other and become able to engage with each other, and the fourth engaging part 75 and the sixth engaging part 93 engage with each other, so that the fixing member 80 is assembled to the vibration-damping member 50.
[0026] Next, we will describe each component that makes up the holder 10.
[0027] First, the holding member 20 will be described with reference to Figures 1-3 and 14-17. As shown in Figure 1, the holding member 20 has a frame-shaped main body 30 to which a holding part 21 for holding the long member P is connected.
[0028] In this embodiment, the frame-shaped main body portion 30 has a pair of wall portions 31, 31 arranged parallel to each other and a pair of wall portions 33, 33 arranged perpendicular to these wall portions 31, 31, forming a substantially rectangular frame shape with one end 35 and the other end 36 open. The pair of wall portions 33, 33 constitute the "frame-shaped main body portion side wall portion" in the present invention.
[0029] Furthermore, one end 35 of the frame-shaped main body 30 refers to the side away from the fixed member 1, and the other end 36 of the frame-shaped main body 30 refers to the side opposite to the one end 35 and closer to the fixed member 1 (the side facing the fixed surface 3 of the fixed member 1). The same meaning applies to "one end" and "other end" in the shaft member 5 described above, and in each part of the vibration-damping member 50 (frame-shaped part 51, etc.) and each part of the fixing member 80 (insertion part 81, etc.) described below.
[0030] Then, the frame-shaped part 51 is inserted through the opening on the other end 36 side of the frame-shaped main body part 30.
[0031] Furthermore, on the outer surface of each wall portion 33 (the surface opposite to the inner surface facing inward of the frame-shaped main body portion 30), a pair of recesses 37, 37 are formed on both sides in the width direction (the direction perpendicular to the arrangement direction of the pair of wall portions 33, 33), recessed to a predetermined depth from the outer surface (see Figure 1). Each recess 37 is open on one end 35 side of the frame-shaped main body portion 30, while the other end 36 side is closed, and extends from one end 35 side to the other end 36 side with a constant width.
[0032] Furthermore, as shown in Figure 3, a pair of protrusions 39, 39 project inward from the frame-shaped main body 30 at positions corresponding to a pair of recesses 37, 37 on each wall portion 33. Each protrusion 39 is provided with a first engagement portion 43 that can be bent and deformed via a U-shaped slit 41 (see Figure 2). In this embodiment, the frame-shaped main body 30 is provided with four first engagement portions 43 (see Figure 3).
[0033] Furthermore, each first engaging portion 43 has a fixed end connected to one end 35 of the frame-shaped main body 30, and a free end positioned on the other end 36 of the frame-shaped main body 30, with this free end protruding inward from the frame-shaped main body 30. The first engaging portion 43 is positioned opposite the fifth engaging portion 91 provided on the fixing member 80 and is capable of engaging with the fifth engaging portion 91 (see Figure 16).
[0034] As shown in Figure 3, a second engaging portion 45 is provided between the opposing inner surfaces 39a, 39a of a pair of protrusions 39, 39 provided on each wall portion 33. As shown in Figure 15, the surface 45a of this second engaging portion 45 that faces one end 35 of the frame-shaped main body portion 30 (hereinafter also simply referred to as "one end surface 45a") is tapered toward the inside of the frame-shaped main body portion 30 and the amount of protrusion gradually increases toward one end 35 of the frame-shaped main body portion 30. The second engaging portion 45 can engage with a third engaging portion 69 provided on the vibration-damping member 50 (see Figure 15).
[0035] On the other hand, the holding portion 21 is connected to one of the pair of wall portions 31, 31 that constitute the frame-shaped main body portion 30.
[0036] As shown in Figures 1 and 10, the holding portion 21 has a bottom wall 23 extending for a predetermined length from the wall portion 31 on the side of the fixed surface 3 in a direction perpendicular to the axial direction of the frame-shaped main body portion 30, and a plurality of holding walls 25 extending along the axial direction of the frame-shaped main body portion 30 at predetermined intervals from the bottom wall 23.
[0037] Furthermore, as shown in Figure 10, multiple holding spaces 27 for holding long members P are defined by the bottom wall 23 and multiple holding walls 25. In addition, multiple holding claws 29 extend diagonally inward toward the bottom wall 23 from the inner surface (the surface facing the holding space 27) of each holding wall 25. As a result, multiple long members P can be held in place in the multiple holding spaces 27 without falling out.
[0038] Next, the vibration-damping member 50 will be described with reference to Figures 4, 5, 10, and 14-17, etc.
[0039] As shown in Figure 1, the vibration-damping member 50 is made of an elastic material and has a frame-shaped portion 51 that is inserted from the side of the fixed member 1 inside the frame-shaped main body portion 30. The frame-shaped portion 51 also has a wall portion 53 provided with an extension piece 60 and a wall portion 55 that is not provided with an extension piece 60.
[0040] Referring together to Figures 4 and 5, the frame-shaped portion 51 of this embodiment has a pair of wall portions 53, 53 arranged parallel to each other and a pair of wall portions 55, 55 arranged perpendicular to these wall portions 53, 53, and has a substantially rectangular frame shape with one end 51a and the other end 51b open. The frame-shaped portion 51 is inserted into the inside of the frame-shaped main body portion 30 from one end 51a, and the insertion portion 81 of the fixing member 80 is inserted from the opening on the one end 51a.
[0041] Furthermore, the frame-shaped portion 51, which is roughly rectangular in shape, is similar in shape to the frame-shaped main body portion 30, which is also roughly rectangular in shape, but is slightly smaller.
[0042] Specifically, the width of each wall portion 53 of the frame-shaped portion 51 (the length in the direction perpendicular to the arrangement direction of the pair of wall portions 53, 53) is formed to be smaller than the width of each wall portion 31 of the frame-shaped main body portion 30 (the length in the direction perpendicular to the arrangement direction of the pair of wall portions 31, 31). Furthermore, the width of each wall portion 53 of the frame-shaped portion 51 (the length in the direction perpendicular to the arrangement direction of the pair of wall portions 53, 53) is formed to be smaller than the width of each wall portion 33 of the frame-shaped main body portion 30 (the length in the direction perpendicular to the arrangement direction of the pair of wall portions 33, 33).
[0043] As a result, the frame-shaped portion 51 can be inserted inside the frame-shaped main body portion 30, and in this inserted state, a predetermined gap is formed between the entire inner circumference of the frame-shaped main body portion 30 and the entire outer circumference of the frame-shaped portion 51.
[0044] Furthermore, the pair of wall portions 55, 55 constituting the frame-shaped portion 51 are formed so that their length (length along the frame-shaped portion insertion direction F1) is shorter than the length of the pair of wall portions 53, 53 on which the extension piece 60 is provided. However, as shown in Figure 12, when the frame-shaped portion 51 is inserted inside the frame-shaped main body portion 30, the portion of the wall portion 55 on one end 51a protrudes by a predetermined length from the opening on one end 35 of the frame-shaped main body portion 30.
[0045] Furthermore, the frame-shaped portion 51 is provided with a contact portion 57 on the other end 51b side, which protrudes more than the other end 36 of the frame-shaped main body portion 30 and abuts against the fixed member 1. This contact portion 57 consists of a flange portion 58 that is in the shape of a thin plate and protrudes outward from the outer circumference of the other end 51b side of the frame-shaped portion 51, and a base portion 59 that protrudes from the surface of the flange portion 58 on the other end 51b side.
[0046] Then, as shown in the insertion direction F1 of the frame-shaped portion in Figure 1, when the vibration-damping member 50 is assembled to the holding member 20 by inserting the frame-shaped portion 51 into the inside of the frame-shaped main body portion 30 from the side of the member to be fixed 1, the flange portion 58 of the contact portion 57 of the frame-shaped portion 51 comes into contact with the end face on the other end 36 side of the frame-shaped main body portion 30 (see Figure 11, etc.), thereby restricting the maximum insertion position of the frame-shaped portion 51 relative to the frame-shaped main body portion 30. The base portion 59 is the part that comes into contact with the fixed surface 3 of the member to be fixed 1 (see Figures 12 and 14).
[0047] Furthermore, the vibration-damping member 50 extends outward from the frame-shaped main body 30 when the frame-shaped portion 51 is inserted inside the frame-shaped main body 30 (see Figure 11), and has a pair of extension pieces 60, 60 that are sandwiched between the frame-shaped main body 30 and the flange portion 95 when the insertion portion 81 is inserted inside the frame-shaped portion 51. In addition, the pair of extension pieces 60, 60 are made bendable outward when pressed against the flange portion 95 of the fixing member 80 or a part of the insertion portion 81 (the pressing surface 101 described later in this embodiment) when the insertion portion 81 is inserted inside the frame-shaped portion 51, as shown in the insertion direction F2 of Figure 1 (see Figure 12).
[0048] To explain the extension piece 60 in more detail, the extension pieces 60, 60 extend from one end (the end on the side of one end 51a of the frame-shaped portion 51) of the pair of wall portions 53, 53 that constitute the frame-shaped portion 51.
[0049] As shown in Figures 4 and 10, each extension piece 60 extends in the same direction as the extension direction of the wall portion 53 (the same direction as the axial direction of the shaft member 5) before the frame portion 51 is inserted inside the frame portion 30. Furthermore, each extension piece 60 extends integrally and continuously from one end of the wall portion 53, and extends straight relative to the wall portion 53 before the frame portion 51 is inserted inside the frame portion 30. Moreover, before the frame portion 51 is inserted inside the frame portion 30, the extension piece 60 extends longer than the end of the wall portion 55 on the end 51a side.
[0050] Furthermore, as shown in Figures 4 and 10, the tip portion 61 of each extension piece 60 in the extension direction (which can also be called one end of the extension piece 60), on its inner surface (as shown in Figure 3, the surface facing inward into the frame-shaped main body 30 before the frame-shaped part 51 is inserted inside the frame-shaped main body 30), has a tapered surface 63 formed on it that gradually reduces the thickness of the extension piece 60 towards the tip of the extension piece 60. Moreover, the pair of extension pieces 60, 60 protrude from the opening on one end 35 side of the frame-shaped main body 30 when the frame-shaped part 51 is inserted inside the frame-shaped main body 30 (see Figure 11).
[0051] Then, each extension piece 60 is pressed by the flange portion 95 or a part of the insertion portion 81 (pressing surface 101) of the fixing member 80 at its tip portion 61, causing the pair of extension pieces 60 to bend outward, starting from the base end (or other end, meaning the connection / boundary portion with one end of the wall portion 53) of each extension piece 60, so that the tip portions 61, 61 separate from each other (see Figure 12).
[0052] In other words, after the frame-shaped part 51 is inserted inside the frame-shaped main body part 30, as shown in the insertion direction F2 of Figure 11, the insertion part 81 of the fixing member 80 is inserted inside the frame-shaped part 51. The tapered surface 63 on the inner surface of the tip part 61 is pressed by the pressing surface 101, which will be described later and is provided on a part of the insertion part 81. This causes each extension piece 60 to bend outward, starting from the base end 62 of the extension piece 60 (see Figure 12). In other words, the pair of extension pieces 60, 60 are pushed apart by the pair of pressing surfaces 101, 101, so that the tip parts 61, 61 are pushed apart from each other.
[0053] Then, in the state in which the pair of extension pieces 60, 60 are spread out as described above, as shown in Figure 14, the outer surface (the surface opposite to the inner surface) of the tip portion 61 of each extension piece 60 abuts against the end 35 side of the pair of wall portions 31, 31 that constitute the frame-shaped main body portion 30, and the flange portion 95 (in this case, the first flange portion 96) abuts against and rests on the inner surface of the tip portion 61 of each extension piece 60.
[0054] In other words, the tip portion 61 of the extension piece 60 is held between the frame-shaped body portion 30 and the flange portion 95, with the frame-shaped portion 51 inserted inside the frame-shaped body portion 30, and the insertion portion 81 inserted inside the frame-shaped portion 51, and the vibration-damping member 50 and the fixing member 80 assembled to the holding member 20.
[0055] As shown in Figure 4, both sides of the tip portion 61 of each extension piece 60 in the width direction W are cut out by the extension piece side tapered portions 64, 64, so that the tip portion 61 is narrowed. The width direction W of the extension piece 60 refers to the direction perpendicular to the extension direction and thickness direction of the extension piece 60.
[0056] In this embodiment, the tip portion 61 of the extension piece 60 is cut off on both sides in the width direction W by extension piece side tapered portions 64 with an inclination angle of 45° (so-called C-chamfering). As a result, the tip portion 61 is formed to be narrower in width than the rest of the piece, that is, shorter in length along the width direction W.
[0057] Furthermore, a first protruding portion 65 is formed on the outer surface of the wall portion 53, extending in the direction of extension and in contact with the inner surface of the frame-shaped main body portion 30, with a length that does not reach the tip (one end) of the extension piece 60.
[0058] In this embodiment, a pair of first protrusions 65, 65 are provided on the outer surface of each wall portion 53 (the surface opposite to the inner surface facing inward of the frame portion 51), in the central portion in the width direction, extending parallel to each other along the extension direction of the wall portion 53. The other end of each first protrusion 65 is connected to a flange portion 58 that constitutes a contact portion 57, and one end extends to a length that does not reach the base end of the extension piece 60.
[0059] Furthermore, when the frame-shaped part 51 is inserted inside the frame-shaped main body part 30, the first protruding portion 65 is positioned to abut against (or be pressed against) the inner surface of the wall portion 31 that constitutes the frame-shaped main body part 30, as shown in Figure 17. The first protruding portion 65 constitutes the "protruding portion" in this invention.
[0060] Furthermore, a pair of slits 66, 66 extending parallel to each other are formed in a predetermined range from the tip (one end) to the base (other end) in the extending direction of each wall portion 55, and flexible elastic pieces 67 are formed through these pairs of slits 66, 66. As shown in Figure 4, a tapered surface 67a is formed on the inner surface (the surface facing inward from the frame-shaped portion 51) of the tip (one end) of each elastic piece 67, gradually thinning the elastic piece 67 toward one end 51a of the frame-shaped portion 51.
[0061] Furthermore, a third engaging portion 69 is provided protruding from the center of the width direction of the outer surface (the surface opposite to the inner surface) of each elastic piece 67. As shown in Figure 15, the surface 69a of the third engaging portion 69 facing the other end 51b of the frame-shaped portion 51 (hereinafter also simply referred to as "other end surface 69a") has a so-called reverse taper shape, where the amount of protrusion gradually increases toward the other end 51b of the frame-shaped portion 51 and toward the other end 51b of the frame-shaped portion 51.
[0062] The other end face 69a of the third engaging portion 69 is positioned opposite one end face 45a of the second engaging portion 45 provided on the frame-shaped main body portion 30 (see Figure 15), so that the third engaging portion 69 and the second engaging portion 45 can engage with each other.
[0063] As shown in Figure 15, the pressing projection 103 of the fixing member 80, which will be described later, is pressed against the inner surface of the elastic piece 67.
[0064] In addition to forming the elastic piece 67, the slit 66 also has the following role. Specifically, as shown in the insertion direction F1 of the frame-shaped part in Figure 1, when the frame-shaped part 51 is inserted into the inside of the frame-shaped main body part 30 from the side of the member to be fixed 1 to assemble the holding member 20 and the vibration-damping member 50, the first engaging part 43 moves within the slit 66. Furthermore, as shown in the insertion direction F2 of the insertion part in Figure 1, when the insertion part 81 is inserted into the inside of the frame-shaped part 51 from the opposite side of the member to be fixed 1 to assemble the vibration-damping member 50 and the fixing member 80, the fifth engaging part 91 provided on the insertion part 81 also moves within the slit 66.
[0065] Furthermore, on the outer surface of the elastic piece 67, a pair of second protrusions 71, 71 are provided on both side edges in the width direction, extending along the insertion direction F2 of the insertion portion. Each second protrusion 71 extends from one end of the elastic piece 67, beyond the base end of the elastic piece 67, onto the outer surface of the wall portion 55, and the other end is connected to the flange portion 58 that constitutes the contact portion 57. In other words, it can be said that the second protrusions 71 extend from the outer surface of the elastic piece 67 and the outer surface of the wall portion 55.
[0066] The second protruding portion 71 is positioned to be pressed against (or to come into contact with) the inner surface of the wall portion 33 that constitutes the frame-shaped main body portion 30 when the frame-shaped portion 51 is inserted inside the frame-shaped main body portion 30, as shown in Figure 17.
[0067] In other words, as shown in Figure 15, with the inner surface of the elastic piece 67 pressed by the pressing projection 103, as shown in Figure 17, the outer surface of the second projection 71 provided on the outer surface of the elastic piece 67 is pressed against the inner surface of the frame-shaped main body 30, that is, the inner surface of the wall portion 33 that constitutes the frame-shaped main body 30.
[0068] Furthermore, on the outer surface of the elastic piece 67, a groove-shaped recessed portion 73 is formed between each second protrusion 71 and the adjacent third engagement portion 69. As shown in Figure 17, this grooved portion 73 is positioned to separate from the inner surface of the frame-shaped main body 30 (in this case, the inner surface of the wall portion 33) when the frame-shaped portion 51 is inserted inside the frame-shaped main body 30.
[0069] Furthermore, as shown in Figure 16, a fourth engaging portion 75 is provided on the inner surface of the pair of wall portions 55, 55 constituting the frame-shaped portion 51, near the other end 51b. Referring also to Figure 5, a pair of fourth engaging portions 75, 75 are projected from both sides in the width direction on the inner surface of each wall portion 55. In other words, the vibration-damping member 50 of this embodiment has a total of four fourth engaging portions 75. The fourth engaging portion 75 can engage with a sixth engaging portion 93 provided on the fixing member 80 (see Figure 16).
[0070] Next, the fixing member 80 will be described with reference to Figures 6-9 and 13-17, etc.
[0071] The fixing member 80 has an insertion portion 81 that is inserted inside the frame-shaped portion 51 and receives the shaft member 5, a locking portion 94 provided inside the insertion portion 81 that locks onto the shaft member 5, and a flange portion 95 that protrudes from one end 81a of the insertion portion 81.
[0072] In this embodiment, the insertion portion 81 is a long plate shape extending for a predetermined length along the insertion direction F2 (insertion direction F2) of the insertion portion 81 into the inside of the frame-shaped portion 51, and has a pair of first extension portions 83, 83 arranged parallel to each other, a tip portion 85 connected to the tip of the pair of first extension portions 83, 83 (the end on the other end 81b side of the insertion portion 81), and a push-in portion 87 which is a roughly rectangular plate shape connected to the base end of the pair of first extension portions 83, 83 (the end on the one end 81a side of the insertion portion 81) and is the part that is pushed in by the worker assembling the holder 10.
[0073] Furthermore, circular shaft holes 85a and 87a are formed in the center of the tip portion 85 and the push-in portion 87, respectively, into which the shaft member 5 is inserted (see Figures 8 and 9). The portion passing through the centers of these shaft holes 85a and 87a forms the center C2 of the insertion portion 81 (see Figure 17).
[0074] Furthermore, a pair of second extensions 88 and 89 are positioned between the tip portion 85 and the push-in portion 87, at a location that does not interfere with the shaft member 5 inserted into the shaft holes 85a and 87a, and which extend columnarly along the insertion direction F2 of the insertion portion. These pair of second extensions 88 and 89 connect the tip portion 85 and the push-in portion 87 to each other, thereby reinforcing the entire fixing member 80.
[0075] Furthermore, as shown in Figure 17, when the insertion portion 81 is viewed in a cross-section perpendicular to the axial direction, the pair of second extension portions 88 and 89 are positioned offset from each other with respect to the center C2 of the insertion portion 81. In this case, one of the second extension portions 88 is offset downwards in the plane of Figure 17 with respect to the center C2 of the insertion portion 81, while the other second extension portion 89 is offset upwards in the plane of Figure 17 with respect to the center C2 of the insertion portion 81.
[0076] Furthermore, as shown in Figures 1 and 6, the outer surface of the insertion portion 81 is provided with a fifth engagement portion 91 that engages with the first engagement portion 43 of the holding member 20, and a sixth engagement portion 93 that engages with the fourth engagement portion 75 of the vibration-damping member 50.
[0077] In this embodiment, fifth engaging portions 91, 91 are provided projecting from predetermined positions on both side edges 84, 84 (see Figure 6) located on both sides of each first extension portion 83 constituting the insertion portion 81, along the surface direction of each first extension portion 83 (a direction perpendicular to the arrangement direction of the pair of first extension portions 83, 83 and along the outer surface of the first extension portion 83).
[0078] Furthermore, sixth engagement portions 93, 93 are formed on both side edges 84, 84 of each first extension portion 83, closer to the fixed member 1 than the fifth engagement portion 91, specifically closer to the end (tip portion 85) on the insertion direction F2 side of the insertion portion.
[0079] The insertion portion 81 is provided with four fifth engaging portions 91 and four sixth engaging portions 93. As shown in Figure 16, the fifth engaging portion 91 is positioned opposite the first engaging portion 43 provided on the frame-shaped main body portion 30 of the holding member 20, and is capable of engaging with the first engaging portion 43. On the other hand, the sixth engaging portion 93 is capable of engaging with the fourth engaging portion 75 provided on the vibration-damping member 50.
[0080] Furthermore, as shown in Figure 7, the fixing member 80 has a plurality of locking portions 94 that engage with the shaft member 5. Each locking portion 94 has a shape that extends diagonally inward from the inner surface of the first extension portion 83 (the surface facing the internal space of the insertion portion 81) toward one end 81a of the insertion portion 81, and a plurality of locking portions are provided on each first extension portion 83.
[0081] As shown in Figure 14, the tip portion 94a of each locking portion 94 in the extending direction is designed to lock onto the shaft member 5 (in this case, the tip portion 94a locks into the screw groove of the stud bolt, which is the shaft member 5). As a result, the holder 10 is fixed to the fixed member 1 via the shaft member 5.
[0082] Furthermore, a flange portion 95 protrudes from the outer circumference of one end 81a of the push-in portion 87 that constitutes the insertion portion 81.
[0083] As shown in Figures 6 and 8, the flange portion 95 in this embodiment consists of a pair of first flange portions 96 that protrude from the outer circumference of one end 81a of the push-in portion 87, where a pair of first extension portions 83, 83 are located, and a pair of second flange portions 97, 98 that protrude perpendicularly to the pair of first flange portions 96, 96 from the outer circumference of one end 81a of the push-in portion 87, where a pair of second extension portions 88, 89 are located. The second flange portion 97 is located on the side of the second extension portion 88, and the second flange portion 98 is located on the side of the second extension portion 89 (see Figure 8).
[0084] As shown in Figures 2 and 12, the pair of second flange portions 97 and 98 are placed so that both widthwise sides of their back surfaces (the sides facing the frame-shaped main body portion 30) abut against the inner surfaces of the tip portions 61 and 61 of the pair of extension pieces 60 and 60. In addition, the widthwise central portion of the back surface of the second flange portion 98 is placed so as to abut against the end portion 51a of a predetermined wall portion 55 that constitutes the frame-shaped portion 51.
[0085] On the other hand, as shown in Figures 6 and 7, the second flange portion 97 has a recess 97a formed in the center of its back surface in the width direction. Therefore, the center of the back surface of the second flange portion 97 in the width direction does not come into contact with the tip portions 61, 61 of the pair of extension pieces 60, 60 (see Figure 15).
[0086] Furthermore, as shown in Figure 9, when the fixing member 80 is viewed from a planar direction (viewed from the insertion direction F2 of the insertion part), the flange portion 95 has a substantially rectangular shape with its outer circumference extending for a predetermined length. The direction in which the flange portion 95 extends is defined as the extension direction E, and the direction perpendicular to this extension direction E is defined as the width direction W.
[0087] Furthermore, the flange portion 95 and the frame-shaped main body portion 30 have the following relationship.
[0088] In other words, as shown in Figure 13, when viewed from the insertion direction F2 of the insertion portion, a clearance CL, CL is provided between the inner surfaces 33a, 33a of the wall portions 33, 33 that form the side wall portion of the frame-shaped main body portion in the present invention, which are positioned opposite the wall portions 55, 55 of the vibration-damping member 50 in the frame-shaped main body portion 30 where the pair of extension pieces 60, 60 of the vibration-damping member 50 are not provided, and the outer edges 95a, 95a of the flange portion 95 which are positioned opposite the wall portions 33, 33 (positioned corresponding to the wall portions 33).
[0089] In this embodiment, as shown in Figure 13, a clearance CL is provided between the outer edge 95a of one second flange portion 97 constituting the flange portion 95 and the inner surface 33a of one wall portion 33 constituting the frame-shaped main body portion 30, and a clearance CL is also provided between the outer edge 95a of the other second flange portion 97 constituting the flange portion 95 and the inner surface 33a of the other wall portion 33 constituting the frame-shaped main body portion 30.
[0090] Furthermore, the flange portion 95 is formed to be narrower than the width of the extension piece 60 provided on the vibration-damping member 50.
[0091] In other words, as shown in Figure 13, when the holder 10 is viewed from a planar direction (viewed from the insertion direction F2 of the insertion part), the length L2 of each first flange portion 96 constituting the flange portion 95 along the width direction W is formed to be shorter than the length L1 of the extension piece 60 along the width direction W.
[0092] Furthermore, as shown in Figure 13, the width of the second flange portions 97, 98, that is, the length L4 along the extension direction E of the flange portion 95 (which can also be said to be the maximum length between the outer edges of the pair of first flange portions 96, 96), is formed to be shorter than the length L3 between the pair of extension pieces 60, 60 (the maximum length between the outer edges of the pair of extension pieces 60, 60).
[0093] As a result, the frame-shaped portion 51 is inserted inside the frame-shaped main body portion 30, and the insertion portion 81 is inserted inside the frame-shaped portion 51, so that the vibration-damping member 50 and the fixing member 80 are assembled to the holding member 20, that is, the pair of extension pieces 60, 60 are spread apart by the flange portion 95 or a part of the insertion portion 81 (pressing surface 101) (see Figures 12 and 14), and as shown in Figure 13, the flange portion 95 does not protrude (does not stick out) from the outer peripheral edge of the pair of extension pieces 60, 60.
[0094] Furthermore, the flange portion 95 is formed such that, in the width direction W of the extension piece 60, it is narrower than the inner dimensions of the frame-shaped main body portion 30.
[0095] In this embodiment, as shown in Figure 13, the length L2 of the first flange portion 96 constituting the flange portion 95 along the width direction W is formed to be shorter than the inner dimension L5 of the pair of wall portions 33, 33 constituting the frame-shaped main body portion 30 (the minimum width between the inner surfaces of the pair of wall portions 33, 33).
[0096] Furthermore, the flange portion 95 is formed such that it is shorter than the tip portion 61 of the extension piece 60 when the extension piece 60 is bent outward.
[0097] In this embodiment, as shown in Figure 13, when the pair of extension pieces 60, 60 are spread apart by the flange portion 95 or a part of the insertion portion 81 (pressing surface 101), the tips of the pair of first flange portions 96, 96 constituting the flange portion 95 are formed to be shorter than the tips of the tip portions 61, 61 of the pair of extension pieces 60, 60.
[0098] Furthermore, as shown in Figure 13, the flange portion 95 has a flange-side tapered portion 100 formed at a position corresponding to the extended one-sided tapered portion 64 when viewed from the insertion direction of the insertion portion 81 into the inside of the frame-shaped portion 51 (insertion portion insertion direction F2).
[0099] In this embodiment, as shown in Figure 13, when viewed from the insertion direction F2 of the insertion portion, the connecting portion (boundary portion) between a predetermined first flange portion 96 and a second flange portion 97 adjacent to the first flange portion 96 is notched (so-called chamfered) by a flange-side tapered portion 100 with an inclination angle of 45°.
[0100] Furthermore, as shown in Figure 13, the flange-side tapered portions 100, 100 located at both ends of the flange portion 95 in the extension direction E and on both sides in the width direction W are provided at positions corresponding to the extension piece-side tapered portions 64, 64 formed on both sides in the width direction W of the tip portion 61 of each extension piece 60. Moreover, a predetermined flange-side tapered portion 100 has a similar shape, but slightly smaller than the extension piece-side tapered portion 64 at the corresponding position.
[0101] Furthermore, as shown in Figure 7, the end of the insertion portion 81 on the flange portion 95 side has a tapered shape and a pressing surface 101 is formed thereon that presses against the inner surface of the tip portion 61 of the extension piece 60, causing the extension piece 60 to bend outward.
[0102] In this embodiment, a pressing surface 101 is formed on the outer surface of the flange portion 95 end (the end on one end 81a side of the insertion portion 81) of the pair of first extension portions 83, 83 constituting the insertion portion 81, that is, the connecting portion (boundary portion) between each first extension portion 83 and the corresponding first flange portion 96, which is tapered and inclined so as to gradually widen toward the flange portion 95 side. In this embodiment, a pair of pressing surfaces 101, 101 are provided.
[0103] Then, after the frame-shaped part 51 is inserted inside the frame-shaped main body part 30, when the insertion part 81 is inserted inside the frame-shaped part 51 and pushed in, the pair of pressing surfaces 101, 101 first press against the inner surfaces (in this case, tapered surfaces 63, 63) of the tip portions 61, 61 of the pair of extension pieces 60, 60, causing the pair of extension pieces 60, 60 to spread apart (see Figures 12 and 14).
[0104] Furthermore, on the outer surfaces of the pair of second extensions 88, 89, opposite to the insertion direction F2, pressing protrusions 103, 103 are provided. These pressing protrusions 103, 103 are configured to press against the inner surface of the frame-shaped portion 51 when the frame-shaped portion 51 is inserted inside the frame-shaped main body portion 30 and the insertion portion 81 is inserted inside the frame-shaped portion 51, so that the outer surface of the frame-shaped portion 51 is pressed against the inner surface of the frame-shaped main body portion 30.
[0105] Each pressing projection 103 is a projection that protrudes outward from the outer surface (which can also be called the outer edge) of the portion of the pair of extensions 88, 89 on the insertion direction F2 side (the tip side and the other end side of the insertion portion 81). Also referring to Figure 15, each pressing projection 103 has a pressing surface 104 that extends parallel to the insertion direction F2 side of the insertion portion, and a tapered surface 105 from the tip of the pressing surface 104 toward the insertion direction F2, with the amount of protrusion gradually decreasing.
[0106] (modified version) The retaining member is integrally formed from a well-known synthetic resin material in all its parts (retaining part, frame-shaped main body, first engaging part, second engaging part, etc.). Furthermore, the shape, structure, layout, etc., of each of the above-mentioned parts of the retaining member are not particularly limited.
[0107] In this embodiment, the holding portion 21 is capable of holding two elongated members P in a way that prevents them from coming loose. However, the holding portion may also be structured to hold one or three or more elongated members in a way that prevents them from coming loose. Furthermore, in this embodiment, the frame-shaped main body portion 30 has four first engaging portions 43 and a pair of second engaging portions 45, 45, but the number of each engaging portion is not particularly limited.
[0108] Furthermore, all parts of the vibration-damping member (frame-shaped part, contact part, extension piece, elastic piece, first and second protruding parts, third and fourth engaging parts, etc.) are integrally formed from an elastic resin material having vibration-damping properties, such as rubber or elastic elastomer. Moreover, the shape, structure, layout, etc., of each of the above parts of the vibration-damping member are not particularly limited.
[0109] In this embodiment, there is a pair of extension pieces 60, 60, but there may be two or more pairs of extension pieces. Also, in this embodiment, the extension piece 60 is designed to bend and deform when pressed by the pressing surface 101, which is part of the insertion portion 81 of the fixing member 80, but the extension piece may be designed to bend and deform when pressed by the flange portion of the fixing member.
[0110] Furthermore, in this embodiment, the pair of extension pieces 60, 60 extend straight relative to the wall portion 53 when the frame portion 51 is inserted inside the frame portion 30 and before the insertion portion 81 is inserted inside the frame portion 51 (see Figure 11), and bend when the insertion portion 81 is inserted inside the frame portion 51 (see Figure 12). However, the pair of extension pieces may be bent outward relative to the wall portions 53, 53 before the frame portion 51 is inserted inside the frame portion 30 (for example, bent at 90°), and the pair of extension pieces can be configured to be sandwiched between the frame portion 30 and the flange portion 95.
[0111] Furthermore, although this embodiment has a pair of third engaging portions 69 and four fourth engaging portions 75, the number of each engaging portion is not particularly limited. Also, two first protrusions 65 and two second protrusions 71 extend from the outer surfaces of the wall portions 53 and 55, respectively, but the first and second protrusions may be one or more.
[0112] Furthermore, all parts of the fixing member (insertion part, fifth and sixth engagement parts, locking part, flange part, etc.) are integrally formed from a well-known synthetic resin material. Also, the shape, structure, layout, etc. of each of the above parts of the fixing member are not particularly limited.
[0113] Furthermore, in this embodiment, the outer circumferential shape of the flange portion 95 is substantially rectangular, but the outer circumferential shape of the flange portion may be, for example, square, triangular, rectangular with 5 or more sides, circular, elliptical, oval, rugby ball, etc., as long as it is formed to be narrower than the width of the extended piece.
[0114] Furthermore, in this embodiment, as shown in Figure 13, clearances CL, CL are provided between the inner surfaces 33a, 33a of the pair of wall portions 33, 33 constituting the frame-shaped main body portion 30 and the outer edges 95a, 95a of the pair of second flange portions 97, 98 constituting the flange portion 95. These clearances CL, CL may be used to provide extension pieces or flange portions.
[0115] For example, the extension piece may be configured such that both sides in the width direction W are widened toward the wall portion 33 (see extension piece 60'; here, for convenience, only one side is widened), so that when the pair of extension pieces are viewed from the planar direction, they form a roughly H shape. Alternatively, the flange portion may be configured such that both ends in the extension direction E, both sides in the width direction W are widened toward the wall portion 33 (see flange portion 95'; here, for convenience, only one side is widened), so that when the flange portion is viewed from the planar direction, it forms a roughly H shape.
[0116] Furthermore, although the fifth engaging portion 91 is projected from both side edges 84, 84 in the width direction of each first extension portion 83, the fifth engaging portion may also be projected from the outer surface of the first extension portion 83, for example.
[0117] Furthermore, in this embodiment, the pressing projection 103 is provided on the outer surface of the second extensions 88, 89, but for example, the pressing projection may be provided on the outer surface of the first extensions 83, 83.
[0118] (Effects and Benefits) Next, we will explain how to use the holder 10, which has the above configuration.
[0119] First, the holder 10, which consists of a holding member 20, a vibration-damping member 50, and a fixing member 80, is assembled.
[0120] In other words, with the third engaging portion 69 of the vibration-damping member 50 aligned in the space between the pair of protrusions 39, 39 provided on the frame-shaped main body portion 30, the frame-shaped portion 51 is inserted into the inside of the frame-shaped main body portion 30 from the fixed member 1, as shown in the frame-shaped portion insertion direction F1 in Figures 1 and 10. That is, one end 51a of the frame-shaped portion 51 is inserted into the frame-shaped main body portion 30 from the opening on the other end 36 side of the frame-shaped main body portion 30.
[0121] Then, the pair of first protrusions 65, 65 slide against the inner surfaces of the pair of walls 31, 31 of the frame-shaped main body 30, and the third engaging portion 69 enters between the inner surfaces 39a, 39a of the pair of projections 39, 39 of the frame-shaped main body 30, while the first engaging portion 43 moves within the slit 66. Furthermore, the outer surface of the third engaging portion 69 is pressed against the inner surfaces of the pair of walls 33, 33 of the frame-shaped main body 30, and the pair of elastic pieces 67, 67 are inserted while bending and deforming so that their tips move closer together.
[0122] Then, the frame-shaped portion 51 is pushed in until the flange portion 58 of the contact portion 57 of the frame-shaped portion 51 contacts the end face on the other end 36 side of the frame-shaped main body portion 30. At this point, a pair of extension pieces 60, 60 of the frame-shaped portion 51 protrude from the end face on the one end 35 side of the frame-shaped main body portion 30 (see Figure 11).
[0123] At the same time, the third engaging portion 69 overcomes the second engaging portion 45 of the frame-shaped main body portion 30, and the deformed elastic piece 67 elastically returns to its original position. As shown in Figure 15, the other end face 69a of the third engaging portion 69 of the vibration-damping member 50 and the one end face 45a of the second engaging portion 45 of the holding member 20 are positioned opposite each other with a predetermined clearance between them. This allows the third engaging portion 69 and the second engaging portion 45 to engage with each other, and the vibration-damping member 50 can be assembled to the holding member 20.
[0124] Subsequently, with the pair of fifth engaging portions 91, 91 of the insertion portion 81 of the fixing member 80 aligned with the pair of slits 66, 66 of the frame-shaped portion 51 inserted inside the frame-shaped main body portion 30, the insertion portion 81 is inserted into the inside of the frame-shaped portion 51 from the opposite side of the member to be fixed 1, as shown in the insertion direction F2 of the insertion portion in Figures 1 and 11. That is, the other end 81b of the insertion portion 81 is inserted into the frame-shaped portion 51 from the opening on one end 51a side of the frame-shaped portion 51.
[0125] Then, the pair of fifth engaging portions 91, 91 of the insertion portion 81 move within the pair of slits 66, 66 of the frame-shaped portion 51, and each fifth engaging portion 91 presses against each first engaging portion 43 of the frame-shaped main body portion 30, causing each first engaging portion 43 to bend and deform outward from the frame-shaped main body portion 30.
[0126] Furthermore, as the insertion portion 81 is pushed into the frame portion 51, the inner surfaces (in this case, tapered surfaces 63, 63) of the tip portions 61, 61 of the pair of extension pieces 60, 60 are pressed by a pair of pressing surfaces 101, 101 provided on a part of the insertion portion 81, causing the pair of extension pieces 60, 60 to bend outward and deform.
[0127] Then, the outer surfaces of the tip portions 61, 61 of the pair of extension pieces 60, 60 come into contact with the end faces of one end 35 of the pair of wall portions 31, 31 that constitute the frame-shaped main body portion 30, and the pair of first flange portions 96, 96 that constitute the flange portion 95 come into contact with the inner surfaces of the tip portions 61, 61 of the pair of extension pieces 60, 60.
[0128] As a result, the maximum insertion position of the insertion portion 81 into the frame-shaped portion 51 is restricted, and the fourth engagement portion 75 of the frame-shaped portion 51 fits into each of the sixth engagement portions 93 of the insertion portion 81, causing the sixth engagement portion 93 and the fourth engagement portion 75 to engage with each other (see Figure 16), thereby enabling the fixing member 80 to be assembled to the vibration-damping member 50.
[0129] At the same time, as each fifth engaging portion 91 overcomes each first engaging portion 43, each first engaging portion 43 elastically returns to its original position, and as shown in Figure 16, the first engaging portion 43 and the fifth engaging portion 91 are positioned opposite each other with a predetermined clearance between them, and the first engaging portion 43 and the fifth engaging portion 91 become able to engage with each other.
[0130] Furthermore, as shown in Figure 14, the pair of pressing surfaces 101, 101 are in close contact with the inner surfaces of the pair of extension pieces 60, 60, and the pair of first flange portions 96, 96 are placed on the inner surfaces of the tip portions 61, 61 of the pair of extension pieces 60, 60, so that the tip portion 61 of the extension piece 60 is sandwiched between the end face on one end 35 side of the wall portion 31 and the first flange portion 96.
[0131] Furthermore, as shown in Figure 15, each pressing projection 103 provided on the fixing member 80 is pressed against the inner surface of each elastic piece 67 provided on the holding member 20.
[0132] Furthermore, as shown in Figure 15, both widthwise sides of the back side of the second flange portion 97 are placed on the tip portion 61 of one of the extension pieces 60. In addition, both widthwise sides of the back side of the second flange portion 98 are placed on the tip portion 61 of the other extension piece 60, and the widthwise central portion of the back side of the second flange portion 98 is placed on the end portion 51a of a predetermined wall portion 55 that constitutes the frame-shaped portion 51.
[0133] Furthermore, as shown in Figure 15, the pressing surfaces 104 and tapered surfaces 105 of the pair of pressing protrusions 103, 103 press against the tapered surfaces 67a, 67a on the inner surfaces of the tip portions of the pair of elastic pieces 67, 67, so that, as shown in Figure 17, the outer surfaces of the pair of second protrusions 71, 71 are pressed against the inner surfaces of the protrusions 39, 39 of the pair of wall portions 33, 33 that constitute the frame-shaped main body portion 30.
[0134] After assembling the holder 10 as described above, the holder 10 is fixed to the member to be fixed 1 via the shaft member 5. That is, the holder 10 is pushed toward the member to be fixed 1 so that it is in a direction that is close to the surface to be fixed 3.
[0135] Then, the shaft member 5 passes through the opening on the other end 51b side of the frame-shaped portion 51 from the other end side, is received inside the insertion portion 81, and engages with the multiple locking portions 94. After that, by pushing the holder 10 in until the base portion 59 of the contact portion 57 of the frame-shaped portion 51 contacts the surface to be fixed 3, the holder 10 can be fixed to the fixed member 1 via the shaft member 5.
[0136] Next, by inserting the elongated member P into the holding space 27 of the holding portion 21, the elongated member P is held by the holding claws 29, and the elongated member P can be positioned on the fixed member 1 via the holder 10 (see Figure 12). Note that the elongated member P may be held before fixing the holder 10 to the fixed member 1.
[0137] Furthermore, in this holder 10, as shown in Figure 14, a pair of extension pieces 60, 60 are sandwiched between the frame-shaped main body 30 and the flange portion 95, and as shown in Figure 13, A clearance CL is provided between the inner surfaces 33a, 33a of the wall portions 33, 33 that form the side wall portions of the frame-shaped main body portion in the present invention, which are positioned opposite the wall portions 55, 55 of the frame-shaped main body portion 30 where the pair of extended pieces 60, 60 of the vibration-damping member 50 are not provided, and the outer edges 95a, 95a of the flange portion 95 which are positioned opposite the wall portions 33, 33.
[0138] Therefore, even if a twisting force (hereinafter also simply referred to as "twisting force") acts on the long member P held by the holding part 21, for example, as shown by the dashed line in Figure 18, such a force acts on the long member P to move closer to or away from the fixed surface 3 of the fixed member 1, it is possible to make it difficult for the frame-shaped main body 30 of the holding member 20 to interfere with the flange portion 95 of the fixed member 80.
[0139] In other words, even if a twisting force acts on the long member P and the frame-shaped main body 30 attempts to come into contact with the flange portion 95, the frame-shaped main body 30 will first come into contact with the extension piece 60 of the vibration-damping member 50 where the pair of extension pieces 60, 60 are provided, thus preventing the frame-shaped main body 30 from coming into direct contact with the flange portion 95.
[0140] Furthermore, in areas where the pair of extension pieces 60, 60 are not provided, as described above, Since clearances CL, CL are provided between the inner surfaces 33a, 33a of the wall portions 33, 33 of the frame-shaped main body portion 30 and the outer edges 95a, 95a of the flange portion 95, in this case as well, when a twisting force is applied to the long member P, it is possible to make it difficult for the frame-shaped main body portion 30 to interfere with the flange portion 95.
[0141] Therefore, in this holder 10, the frame-shaped main body 30 is less likely to interfere with the flange portion 95 in both the areas where the pair of extension pieces 60, 60 of the vibration-damping member 50 are provided and the areas where the pair of extension pieces 60, 60 are not provided. As a result, the holder 10 is less likely to generate vibration transmission paths that do not go through the vibration-damping member 50 (because it is possible to suppress the generation of vibration transmission paths caused by the contact between the frame-shaped main body 30 and the flange portion 95), and the vibration-damping performance of the vibration-damping member 50 can be fully demonstrated.
[0142] Furthermore, in this embodiment, as shown in Figure 13, the flange portion 95 is formed to be narrower than the inner dimensions of the frame-shaped main body portion 30 in the width direction of the extension piece 60.
[0143] According to the above embodiment, the flange portion 95 is formed to be narrower in the width direction of the extension piece 60 than the inner dimensions of the frame-shaped main body portion 30, so that the frame-shaped main body portion 30 is less likely to interfere with the flange portion 95.
[0144] Furthermore, in this embodiment, as shown in Figure 13, the flange portion 95 of the fixing member 80 is formed to be narrower than the width of the extension piece 60 of the vibration-damping member 50.
[0145] According to the above embodiment, the flange portion 95 is formed to be narrower than the width of the extension piece 60 of the vibration-damping member 50, so that the frame-shaped main body portion 30 is less likely to interfere with the flange portion 95.
[0146] Furthermore, in this embodiment, the flange portion 95 is formed to be shorter than the tip portion 61 of the extension piece 60 when the extension piece 60 is bent outward (see Figure 13).
[0147] According to the above embodiment, the flange portion 95 is formed to be shorter than the tip portion 61 of the extension piece 60 when the extension piece 60 is bent outward, so that the frame-shaped main body portion 30 is less likely to interfere with the flange portion 95 of the fixing member 80.
[0148] Furthermore, in this embodiment, both sides of the tip portion 61 of the extension piece 60 in the width direction W are cut out by extension side tapered portions 64, 64, so that the tip portion 61 is formed to be narrow, and flange side tapered portions 100, 100 are formed on the flange portion 95 at positions corresponding to the extension side tapered portions 64, 64 when viewed from the insertion direction of the insertion portion 81 into the inside of the frame-shaped portion 51 (insertion portion insertion direction F2) (see Figure 13).
[0149] According to the above embodiment, both sides of the tip portion 61 of the extension piece 60 in the width direction W are cut out by the tapered portions 64, 64 on the extension piece sides, and the tip portion 61 is formed to be narrow, which improves the ease of insertion when inserting the frame-shaped portion 51 into the inside of the frame-shaped main body portion 30.
[0150] Furthermore, since the flange portion 95 has flange-side tapered portions 100, 100 formed at positions corresponding to the extended one-sided tapered portions 64, 64 when viewed from the insertion direction F2 of the insertion portion, when the flange portion 95 presses against the extended piece 60, it is possible to maximize the area that can be pressed by the flange portion 95 while making it less likely for the frame-shaped main body portion 30 to interfere with the flange portion 95.
[0151] Furthermore, it is possible to reliably prevent the flange portion 95 from protruding beyond the outer edge of the extension piece 60. If a tapered portion is provided on only one of the extension piece 60 or the flange portion 95, there is a risk that the outer edge of the flange portion 95 will protrude beyond the outer edge of the extension piece 60.
[0152] Furthermore, in this embodiment, the frame-shaped portion 51 has a wall portion 53 on which an extension piece 60 is provided, and a protruding portion (here, a first protruding portion 65) is formed on the outer surface of the wall portion 53, extending to a length that does not reach the tip of the extension piece 60 and in contact with the inner surface of the frame-shaped main body portion 30.
[0153] According to the above embodiment, as shown in Figures 14 and 17, the protruding portion (first protruding portion 65) formed on the outer surface of the frame-shaped portion 51 comes into contact with the inner surface of the frame-shaped main body portion 30 of the holding member 20, thereby improving the vibration damping performance of the vibration damping member 50.
[0154] Furthermore, since the protruding portion (first protruding portion 65) extends on the outer surface of the wall portion 53 to a length that does not reach the tip of the extension piece 60, when the frame-shaped portion 51 is inserted inside the frame-shaped main body portion 30, and then the insertion portion 81 is inserted inside the frame-shaped portion 51, and the extension piece 60 is pressed against the flange portion 95 or a part of the insertion portion 81 (pressing surface 101) and bent outward, the extension piece 60 does not get in the way of bending, making it easier to bend and deform the extension piece 60 at a predetermined position.
[0155] Furthermore, in this embodiment, the end of the insertion portion 81 on the flange portion 95 side has a tapered shape and a pressing surface 101 that presses against the inner surface of the tip portion 61 of the extension piece 60, causing the extension piece 60 to bend outward (see Figures 7 and 14).
[0156] According to the above embodiment, the end of the insertion portion 81 on the flange portion 95 side has a tapered shape and a pressing surface 101 is formed which presses against the inner surface of the tip portion 61 of the extension piece 60, causing the extension piece 60 to bend outward. Therefore, when the frame portion 51 is inserted inside the frame portion 51, and then the insertion portion 81 is inserted inside the frame portion 51, it is possible to easily bend and deform the extension piece 60 at a predetermined position.
[0157] Furthermore, with the insertion portion 81 inserted inside the frame-shaped portion 51, it becomes easier to bring the extension piece 60 into close contact with the frame-shaped main body portion 30 (as shown in Figure 14, here it becomes easier to bring the outer surface of the tip portion 61 of the extension piece 60 into close contact with the end surface on one end 35 side of the wall portion 31 of the frame-shaped main body portion 30), making it less likely for the frame-shaped main body portion 30 to interfere with the flange portion 95. If there is a gap between the extension piece 60 and the frame-shaped main body portion 30, the extension piece 60 becomes more prone to deformation after the vibration-damping member 50 and the fixing member 80 are assembled to the holding member 20, and the frame-shaped main body portion 30 and the flange portion 95 become more prone to interference.
[0158] Furthermore, in this embodiment, the insertion portion 81 has extensions (a pair of second extensions 88, 89) that extend in the insertion direction F2 (insertion direction F2) of the insertion portion 81 into the inside of the frame-shaped portion 51, and pressing protrusions 103, 103 are provided on the outer surfaces of the pair of second extensions 88, 89, at least on the portion opposite to the insertion direction F2, and these pressing protrusions 103, 103 are configured to press against the inner surface of the frame-shaped portion 51 when the frame-shaped portion 51 is inserted into the inside of the frame-shaped main body portion 30 and the insertion portion 81 is inserted into the inside of the frame-shaped portion 51, so that the outer surface of the frame-shaped portion 51 (the outer surface of the second protrusion 71) is pressed against the inner surface of the frame-shaped main body portion 30 (see Figures 15 and 17).
[0159] According to the above embodiment, when the frame-shaped portion 51 is inserted inside the frame-shaped main body portion 30 and the insertion portion 81 is inserted inside the frame-shaped portion 51, the pressing protrusions 103, 103 provided on the second extension portions 88, 89 press against the inner surface of the frame-shaped portion 51, thereby causing the outer surface of the frame-shaped portion 51 (the outer surface of the second protruding portion 71) to be pressed against the inner surface of the frame-shaped main body portion 30 (the inner surfaces of the protruding portions 39, 39 of the pair of wall portions 33, 33) (see Figures 15 and 17).
[0160] Therefore, even if a twisting force acts on the long member P held by the holding part 21, tilting, tipping, or falling of the frame-shaped main body 30 can be suppressed, and the frame-shaped main body 30 of the holding member 20 is less likely to interfere with the fixing member 80. As a result, it is possible to make it less likely for vibration transmission paths that do not go through the vibration-damping member 50 to occur in the holder 10, so that the vibration-damping performance of the vibration-damping member 50 can be fully demonstrated.
[0161] Furthermore, in this holder 10, even if a twisting force is applied to the elongated member P held by the holding portion 21, the vibration damping performance of the vibration damping member 50 can be more reliably demonstrated through the synergistic effect of the structure, in which the flange portion 95 of the fixing member 80 is formed to be narrower than the width of the extended piece 60 of the vibration damping member 50, and the structure described in paragraph 0142.
