  In the holders described in Patent Literature 1 and Patent Literature 2, a clamp portion that holds a pipe as a long member has an open portion at the top for receiving the pipe, and is formed by a pair of side walls and a bottom portion. It is formed to accommodate the pipe in the shape space, the elastic holding piece extends obliquely from the open part of the side wall toward the bottom part, and the pipe is easily pushed into the clamp part from the open part to the clamp part. The pipe accommodated easily and held in the clamp part is held so that its side surface abuts on the tip of the elastic holding piece and does not come off the clamp part. Another elastic holding piece is provided on the bottom side of the clamp portion and holds the clamp portion without rattling, whether it is a small diameter pipe or a large diameter pipe. Patent Documents 1 and 2 do not disclose that the vibration of the held pipe is not transmitted to the body panel (or the amount of vibration transmission is reduced).

  In the holders described in Patent Literature 3 and Patent Literature 4, a clamp portion that holds a pipe as a long member has an open portion at the top for receiving the pipe, and is formed by a pair of side walls and a bottom portion. Formed to accommodate the pipe in the shaped space, a pair of elastic holding pieces extend obliquely toward the bottom from the open part of the side wall, and the pipe is clamped with a simple operation just by pushing it into the clamp part from the open part It is easily accommodated in the part and held so that the accommodated pipe does not come off the clamp part. A pair of flexible side holding pieces are provided on the side wall of the clamp portion so that pipes having different diameters can be accommodated in the clamp portion. In the holder described in Patent Document 3, a flexible bulge is provided at the bottom of the clamp, and the bottom portion of the pipe is held even when a small diameter pipe does not reach the bottom. The holders described in Patent Document 3 and Patent Document 4 have side holding pieces on the side walls so that a large-diameter pipe or a small-diameter pipe can be held by the clamp portion. Such a holder is not provided with a configuration for preventing the vibration of the pipe from being transmitted to the attached member through the holder. The pair of flexible side holding pieces of the holders described in Patent Document 3 and Patent Document 4 can be used even when the pipe accommodated in the clamp portion vibrates laterally between the pair of side walls (or It does not prevent transmission to the rigid side wall of the holder (or to the rigid bottom) even if it vibrates up and down between the bottom part and the open part, and pipes with different diameters can be accommodated in the clamp part. There is only such flexibility. Moreover, the bulging part of the bottom part of the clamp part of the holder described in Patent Document 3 is only flexible so that pipes having different diameters can be accommodated in the clamp part. Therefore, there is a need for a holder that can prevent transmission of vibration when the pipe vibrates in the vertical direction in the clamp part of the holder, and can also prevent transmission of lateral vibration that vibrates in the side wall direction of the clamp part. .

  In the holder described in Patent Document 5, the clamp portion that holds the pipe as the long member has an open portion at the top for receiving the pipe in a U-shaped space formed by a pair of side walls and a bottom portion. It is formed to accommodate the pipe, and a pair of elastic holding pieces extend obliquely from the open part of the side wall toward the bottom part, and the pipe can be easily pushed into the clamp part by simply pushing it into the clamp part from the open part. It is accommodated and held so that the accommodated pipe does not come off from the clamp part. The elastic holding piece is formed in a specific shape to reduce the pushing force of the pipe. A pair of other elastic holding pieces are provided on the side wall of the clamp part so as to elastically press the pipe from the side wall to the center of the clamp part so that the pipe can be accommodated without rattling. This another elastic holding piece is for elastically pressing the pipe to the center of the clamp part to prevent rattling, and allows pipes having different diameters to be accommodated in the clamp part. Another elastic holding piece is a rigid side wall of the holder even if the pipe accommodated in the clamp part vibrates laterally between the side walls (or even if it vibrates up and down between the bottom part and the open part). (Or to the rigid bottom) is not prevented. Therefore, there is a need for a holder that can prevent vibration transmission when the pipe vibrates in the vertical direction in the clamp part of the holder, and can also prevent transmission of lateral vibration that vibrates in the side wall direction of the clamp part. It has been.

  In the holder described in Patent Document 6, a clamp portion that holds a pipe as a long member has an open portion at the top for receiving the pipe, and a U-shaped space formed by a pair of side walls and a bottom portion. It is formed to accommodate the pipe, and a pair of elastic holding pieces extend obliquely from the open part of the side wall toward the bottom part, and the pipe can be easily pushed into the clamp part by simply pushing it into the clamp part from the open part. It is accommodated and held so that the accommodated pipe does not come off from the clamp part. On the side wall of the clamp part, it extends from the side wall to the inside of the clamp part so that even a small-diameter pipe can be accommodated without rattling, and the part on the bottom side of the pipe is elastic upward A pair of other elastic holding pieces that are pressed against each other are provided. Another elastic holding piece holds a pipe having a different diameter in the clamp portion, even if it is a small-diameter pipe without looseness in the clamp portion. Another elastic holding piece is the rigidity of the holder even if the pipe accommodated in the clamp part vibrates laterally between a pair of side walls (or even if it vibrates up and down between the bottom part and the open part). It is not intended to prevent transmission to the side wall (or to the rigid bottom) of the pipe, but to prevent rattling of the pipe, or to allow pipes having different diameters to be accommodated in the clamp portion.

  Accordingly, an object of the present invention is to use a vertical member in a clamp portion between a long member and a mounted member in a holder for a long member having a U-shaped clamp portion without using a soft material member. It is an object of the present invention to provide a long member holder that prevents or reduces transmission of vibration and lateral vibration.

In order to achieve such an object, according to the present invention, a clamp portion that holds a long member and a main body portion that is fixed to a member to be attached are provided, the long member is held by the clamp portion, and the main body portion is By fixing to the attached member, the long member is a holder for the long member configured to be attached to the attached member,
The clamp part includes a pair of side walls and a bottom part that form a U-shaped space in which an upper part is opened and holds and holds a long member;
The clamp part includes a first elastic holding piece that extends obliquely from the upper part of the pair of side walls toward the bottom part, and the first elastic holding piece is detached from the long member held by the clamp part. Has a tip that prevents
The clamp part extends from the bottom part of the lower part of the pair of side walls to the upper part of the clamp part along the side wall and is spaced apart from the side wall, and elastically deforms the long member in the lateral direction. A second elastic holding piece supported by
Between each of the second elastic holding pieces and the side wall, a reinforcing beam for sharing the stress applied to the second elastic holding piece is provided at a position away from the base portion of the second elastic holding piece. A retainer is provided.
In the holding tool, the clamp portion extends from each of the pair of side walls toward the bottom portion, and elastically contacts the surface of the bottom portion side of the long member held by the clamp portion. The third elastic holding piece is connected to the second elastic holding piece at the root portion.

  As described above, on each of the pair of side walls of the clamp part, the third elastic holding piece extends toward the bottom, and the second elastic holding piece extends toward the top along the side wall, and is accommodated in the clamp part. Since the elongated member is held in the U-shaped space of the clamp part in a state of being separated (floated) from the bottom and the side wall, the vibration of the long member is prevented from being directly transmitted to the bottom and the side wall. The transmission amount of the vibration of the member is reduced, and each of the pair of second elastic holding pieces and the pair of third elastic holding pieces reduces the vibration of the long member, so the vibration of the long member itself is reduced. However, this also reduces the amount of vibration transmitted by the long member. Therefore, the holder according to the present invention prevents or reduces the transmission of vibration in the holder even if the long member vibrates in the vertical and lateral directions in the clamp portion without using a member made of a soft material. The transmission of vibration between the elongate member and the attached member is prevented or reduced. Since the reinforcing beam prevents stress concentration on the root portion, it is not necessary to increase the strength of the root portion, the amount of vibration transmitted through the root portion can be reduced, and the elasticity of the second elastic holding piece is reinforced. Since it is not hindered by the beam, the amount of vibration transmitted can be kept small.

In the holding tool, the reinforcing beam is formed so that the thickness of the reinforcing beam is thinner than that of the second elastic holding piece in a cross section transverse to the length direction between the second elastic holding piece and the side wall.
In the holder, the reinforcing beam is formed such that the width of the reinforcing beam is shorter than that of the second elastic holding piece in a cross section that crosses the length direction between the second elastic holding piece and the side wall.

  In the holder, each of the third elastic holding pieces is formed away from the bottom in a state where there is no long member in the space of the clamp part, and on the bottom side of the long member held by the clamp part. It is formed so as to elastically hold the long member from the bottom by elastically pushing up the surface upward.

  In the holder, each of the second elastic holding pieces is in a state in which the long member is separated from the side wall by elastically pressing the side wall side surface of the long member held by the clamp portion to the opposite side wall side. It is formed so as to be held elastically.

  In the holder, each of the second elastic holding pieces and each of the third elastic holding pieces has a thickness (length in the radial direction of the long member) that reduces vibration of the long member held in the clamp portion. It has a length (length along the circumferential direction of the long member) and a width (length in the longitudinal direction of the long member).

  In the holder, the root portion is formed of a plate-like body that extends upward along the side wall away from the side wall from a position on the bottom side of the side wall so as to be continuous with the second elastic holding piece, and the third elastic holding piece. Extends from the base part to the bottom part while being separated from the side wall.

  In the holder, each of the second elastic holding pieces extends in the longitudinal direction of the long member in the middle between the root portion and the reinforcing beam so as to reduce a contact area with the side surface of the long member. A protrusion is formed, and the second elastic holding piece comes into contact with the long member only at the protrusion.

It is a perspective view of the holder of the long member concerning one embodiment of the present invention. It is a front view of the holder of FIG. It is the sectional view on the AA line of the holder of FIG. It is a perspective view which shows a mode that the pipe (elongate member) was attached to the to-be-attached member (body panel) with the holder of FIG. It is a figure which shows the vibration of the pipe accommodated in the clamp part 6 of the holder of FIG. 1, and the motion of the 2nd elastic holding piece and 3rd elastic holding piece accompanying it.

  Hereinafter, a long member holder 1 according to an embodiment of the present invention will be described with reference to the drawings. The holder 1 is integrally formed of a hard plastic material. 1 and 2 show the entire holder 1. FIG. 3 is a cross-sectional view taken along line AA of the clamp portion 6 of the holder 1 of FIG. FIG. 4 shows a state in which the holder 1 holding the pipes 11A, 11B, 11C, and 11D as the long members in the clamp portions 3 to 6 is attached to the body panel 8 as the attached member. FIG. 5 shows the movement of the second elastic holding pieces 22A and 22B and the third elastic holding pieces 19A and 19B when the pipe 11D vibrates in the clamp portion 6 according to the present invention.

  As shown in FIGS. 1 and 2, the holder 1 includes a main body 2 fixed to a member to be attached such as a body panel of an automobile, and four clamp portions that hold a long member such as a pipe or a wire harness. 3, 4, 5, and 6. The four clamp portions 3 to 6 are integrally connected to each other by a base portion 7 that forms the bottom portion of each clamp portion, and a wall portion that forms a side wall of each clamp portion rises vertically from the base portion 7. ing. Furthermore, the base portion 7 is integrally formed from the bottom of the clamp portions 3 to 6 to the lower portion of the main body portion 2, and integrally connects the clamp portions 3 to 6 and the main body portion 2. The main body 2 is provided with a fixing portion 9 that is fixed to the body panel 8 (attached member) shown in FIG. The fixing portion 9 is formed to have a hollow center portion so as to receive a rod-like stud (not shown) having a screw or a circumferential groove, which is erected on the body panel 8, and in the hollow portion, there is a thread groove of the stud. Alternatively, a plurality of locking claws 10 that are elastically locked to the circumferential groove are formed as stud locking portions, and an opening through which the stud can be inserted is formed in the upper portion of the fixing portion 9. With such a configuration, the retaining claw 10 is pressed into the thread groove or the circumferential groove of the stud by pressing the holder 1 against the body panel 8 on which the stud is erected so that the stud is received in the hollow portion through the opening of the fixing portion 9. As shown in FIG. 4, the holder 1 holding the pipes 11A, 11B, 11C, and 11D as the long members is fixed to the body panel 8 so that the pipes 11A to 11D are connected to the body panel. 8 is attached. In the illustrated example, the fixing portion 9 is configured to be locked to the stud. However, the fixing portion 9 may be configured to be locked to the T stud, or may be formed on the body panel 6. It may have a hook-shaped clip that is inserted into and fixed to the mounting hole, and may be another fixing means that can attach the holder to the member to be mounted.

  In the illustrated embodiment, the clamping parts 3 to 6 have two known clamping parts 3 and 4 and two clamping parts 5 and 6 according to the invention. Such known clamping parts 3 and 4 may or may not be present. Moreover, although the two clamp parts 5 and 6 which concern on this invention are provided, the number is arbitrary and may be one or two or more. In the known clamp parts 3 and 4, the elastic holding piece 13 extends obliquely from the upper part of the side wall toward the bottom part, and when the pipe is pushed from the open part of the clamp part 3 or 4 toward the bottom part, the clamp part 3 or 4. Is housed in. Since the known clamp parts 3 and 4 are well known, further explanation is omitted.

  Since each of the clamp parts 5 and 6 is basically the same in function and configuration, the structure and operation of the clamp part 6 will be described as a representative. About the structure and effect | action of the other clamp part 5, since the same code | symbol as the element of the clamp part 6 is attached | subjected to drawing, please refer to description of the clamp part 6. FIG. The clamp portion 6 (hereinafter, the same applies to the clamp portion 5) is formed so as to accommodate a pipe as a long member in a U-shaped space formed by a pair of side walls 14A, 14B and a bottom portion 15. Yes. The clamp portion 6 has an open portion 17 for receiving the pipe at the top, and a pair of first elastic holding pieces 18A and 18B extend obliquely toward the bottom portion 15 from the open portions of the side walls 14A and 14B, respectively. It is easily accommodated in the clamp part by a simple operation of pushing into the clamp part 6 from the open part 17. The first elastic holding pieces 18A, 18B hold the first elastic holding pieces 18A, 18B so that the tips of the first elastic holding pieces 18A, 18B come into contact with the upper surface of the pipe accommodated in the clamp part 6 and do not come off the clamp part 6.

  A pair of leaf spring-shaped third elastic holding pieces 19 </ b> A and 19 </ b> B are provided so as to extend obliquely from the side walls 14 </ b> A and 14 </ b> B on the bottom 15 side of the clamp portion 6 toward the bottom 15. Specifically, the pair of third elastic holding pieces 19A, 19B are separated from the side walls toward the bottom 15 from the tips of the base portions 21 (described later) extending from the side walls 14A, 14B on the bottom 15 side of the clamp portion 6 and It extends obliquely so as not to contact the bottom portion 15 and ends in front of the center of the U-shaped space of the clamp portion 6. The third elastic holding pieces 19A and 19B are formed so as to receive the surface on the bottom side of the pipe 11D accommodated in the clamp portion 6 at two places and to elastically push the pipe upward. By the third elastic holding pieces 19A and 19B, the pipe accommodated in the clamp portion 6 is pushed up from the bottom portion 15 so as not to move in the vertical direction and is elastically held in a state of floating from the bottom portion 15. The pipe is in direct contact with the bottom of the clamp part even if the third elastic holding piece holds the pipe even if the pipe vibrates vertically in the clamp part (from the bottom part to the open part or from the open part to the bottom part). Therefore, the amount that the vibration of the pipe in the vertical direction is directly transmitted to the clamp part is reduced, thereby reducing the transmission of vibration between the mounted member such as the body panel to which the holder is attached and the pipe. Yes.

  The plate spring-shaped third elastic holding pieces 19A and 19B have a thickness (the length of the held pipe in the radial direction) so that the elasticity reduces (that is, brakes) the vibration in the vertical direction of the pipe. The length (length along the circumferential direction of the held pipe) and the width (length in the longitudinal direction of the held pipe) are selected, and the vertical vibration of the pipe itself is also reduced. As a result, the vibration of the pipe is further reduced, so that the amount of vibration transmitted from the pipe to the mounted member is reduced by the holder 1.

  A pair of third elastic holding pieces 19A, 19B extend from the tip of the root portion 21 to the clamp portion 6 (and the clamp portion 5) of the holder 1, and a pair of leaf spring-shaped second elastic holding pieces 22A, 22B is formed to extend toward the upper portion of the clamp portion 6 so as to rise substantially parallel to the side walls 14A and 14B, but apart from the side walls 14A and 14B. The pair of leaf spring-shaped second elastic holding pieces 22A and 22B vibrate between the two side walls 14A and 14B opposed to each other by the pipe accommodated in the clamp portion 6 (also referred to as “laterally vibrates” in this document). ) Is regulated. Specifically, the pair of second elastic holding pieces 22A and 22B are pushed away from the side walls 14A and 14B by the elasticity by pushing them back to the center of the accommodating space of the clamp portion 6 when the pipe vibrates in the lateral direction. Elastically held in a state. Since the second elastic holding pieces 22A and 22B hold the pipe, the pipe does not directly contact the side walls 14A and 14B of the clamp portion even if the pipe vibrates in the lateral direction in the clamp portion 6. The amount of vibration transmitted directly to the clamp portion is reduced, thereby reducing the transmission of vibration between a member to be attached such as a body panel to which the holder is attached and the pipe. The second elastic holding pieces 22A and 22B have a thickness (length in the radial direction of the held pipe) and length (holding) so that the elasticity reduces (that is, brakes) the vibration in the lateral direction of the pipe. The length (in the circumferential direction of the pipe) and the width (length in the longitudinal direction of the held pipe) are selected to reduce the vibration in the lateral direction of the pipe itself. This further reduces the amount of vibration transmitted from the pipe to the attached member.

  The second elastic holding pieces 22A, 22B and the third elastic holding pieces 19A, 19B are connected by a root portion 21 that connects the second elastic holding pieces 22A, 22B to the side walls. As described above, the vibration of the pipe held in the space of the clamp portion 6 by the first elastic holding pieces 18A and 18B, the second elastic holding pieces 22A and 22B, and the third elastic holding pieces 19A and 19B is the second elastic holding piece. The holding pieces 22A and 22B and the third elastic holding pieces 19A and 19B are configured to decrease (brake) by the spring elasticity. In the illustrated embodiment, the second elastic holding pieces 22A and 22B are formed substantially the same in thickness, length and width of the third elastic holding pieces 19A and 19B, and the respective elasticity is substantially the same. Selected.

  The second elastic holding pieces 22A and 22B and the third elastic holding pieces 19A and 19B are connected to the corresponding side walls 14A and 14B by the root portion 21, respectively. The root portion 21 connects the second elastic holding pieces 22A and 22B and the third elastic holding pieces 19A and 19B to the corresponding side walls 14A and 14B with a certain strength so that each can elastically hold the pipe. In addition, the root portion 21 maintains spring elasticity for braking the vibration in the vertical direction of the pipe by the third elastic holding pieces 19A and 19B, and the vibration in the horizontal direction of the pipe by the second elastic holding pieces 22A and 22B. It is formed so as to maintain the spring elasticity for braking. In the illustrated embodiment, the root portion 21 is formed of a plate-like body extending upward along the side walls 14A and 14B from the position on the bottom side of the side walls 14A and 14B so as to be continuous with the second elastic holding pieces 22A and 22B. The third elastic holding pieces 19 </ b> A and 19 </ b> B extend from the tip of the root portion 21 so as to be folded back to the bottom portion 15.

  When the pipe held in the pipe holding space of the clamp portion 6 vibrates vertically and laterally, the second elastic holding pieces 22A and 22B and the third elastic holding pieces 19A and 19B vibrate in accordance with the vibration of the pipe, The stress of the vibration accompanying the vibration of the pipe is concentrated on the root portion 21 connecting the second elastic holding pieces 22A and 22B and the third elastic holding pieces 19A and 19B. In order to prevent damage to the root portion 21 due to this stress concentration, it is necessary to increase the strength of the root portion 21, but the second elastic holding piece while reducing the transmission of vibration from the pipe held by the clamp portion 6. In order to maintain the elasticity for damping the vibration of the pipe by the 22A, 22B and the third elastic holding pieces 19A, 19B, it is not desirable to increase the strength of the base portion 21. In the present invention, a reinforcing beam 23 is formed between the second elastic holding piece 22A and the side wall 14A and between the second elastic holding piece 22B and the side wall 14B at positions away from the root portion 21, respectively. The strength of the root portion 21 is reinforced. Specifically, the reinforcing beam 23 is formed to extend from the front ends of the second elastic holding pieces 22A and 22B to the side walls 14A and 14B substantially in parallel with the root portion 21 (extending obliquely toward the bottom 15). . The reinforcing beam 23 reinforces the root portion 21 by sharing the stress caused by the vibration of the pipe at the root portion 21, while reducing the elasticity of the second elastic holding pieces 22 </ b> A and 22 </ b> B to a level that reduces the vibration of the pipe. It is formed so as to maintain (not increase rigidity). Therefore, as shown in FIG. 3, the reinforcing beam 23 has a thickness of the second elastic holding piece in a cross section that traverses the length direction connecting the second elastic holding pieces 22A and 23B and the side walls 14A and 14B. It is formed thinner than 22A and 22B, and the width is shorter than the second elastic holding pieces 22A and 22B.

In each of the second elastic holding pieces 22A and 22B, the longitudinal direction of the pipe is arranged at the contact portion on the side surface of the pipe between the root portion 21 and the reinforcing beam 23 so as to reduce the contact area with the side surface of the pipe. A ridge 25 extending in the direction is formed. The protrusion 25 holds the pipe while the second elastic holding pieces 22A and 22B are in contact with the side surface of the pipe without impairing its elasticity, and reduces the contact area with the pipe. The amount transmitted to the pieces 22A and 22B is reduced. The reinforcing beam 23 is connected to the side walls 14 </ b> A and 14 </ b> B at substantially the same height as the protrusion 25, and the connecting portion is a thick portion 23 a, and the connecting portion of the reinforcing beam 23 is reinforced. The reinforcing beam 23 is thin except for the connection portion, and is easily moved in the lateral direction by vibration of the pipe.
In addition, the third elastic holding pieces 19A and 19B have beads 26 that abut on the side surfaces of the pipes at their tips (ends close to the bottom 15) so as to reduce the contact area with the side surfaces of the pipes. By means of the bead 26, the third elastic holding pieces 19A and 19B abut against the side surface of the pipe without impairing elasticity to hold the pipe, reduce the contact area to the pipe and reduce the transmission of vibration of the pipe. When the pipe 11D vibrates, a portion where the bead 26 is displaced and corresponds to the bottom portion 15 is a sloped stopper portion 15a.

  A first elastic holding piece 18 </ b> A when the pipe 11 </ b> D (and 11 </ b> C) held by the clamp portion 6 (and the clamp portion 5) of the long member holder 1 having the above configuration vibrates in the holding space of the clamp portion 6; The operation of 18B, the second elastic holding pieces 22A, 22B, and the third elastic holding pieces 19A, 19B will be described with reference to FIG. In FIG. 5, the first elastic holding pieces 18 </ b> A, 18 </ b> B prevent the upper surface of the pipe 11 </ b> D in the holding space of the clamp unit 6 from being pressed downward and prevent the pipe 11 </ b> D from coming off the clamp unit 6. The third elastic holding pieces 19A and 19B elastically hold the surface on the bottom side of the pipe 11D so as to push upward, and keep the first elastic holding pieces 18A and 18B in contact with the upper surface of the pipe 11D. To do. The second elastic holding pieces 22A, 22B elastically hold the surface of the pipe 11D on the side wall 14A, 14B side so as to press against the opposite side wall 14B, 14B side, thereby holding the pipe 11D in the lateral direction of the arrow 29 (side wall 14A). And the position of the clamp portion 6 in the center of the holding space.

  In the holder 1, when the pipe 11D held by the clamp part 6 vibrates in the upward direction indicated by the arrow 27, the third elastic holding pieces 19A and 19B push the surface on the bottom side of the pipe 11D upward. The first elastic holding pieces 18A and 18B are kept in contact with the upper surface of the pipe 11D. By the third elastic holding pieces 19 </ b> A and 19 </ b> B, the pipe accommodated in the clamp portion 6 is pushed up from the bottom portion 15 so as not to move in the vertical direction, and is elastically held in a state of floating from the bottom portion 15. Even if the pipe 11D vibrates in the vertical direction of the arrow 27 in the clamp part 6 (the direction from the bottom part to the open part or the direction from the open part to the bottom part), the pipe does not directly contact the bottom part of the clamp part. The amount of vibration directly transmitted to the clamp portion is reduced, thereby reducing the transmission of vibration between a member to be attached such as a body panel to which the holder is attached and the pipe. The plate spring-shaped third elastic holding pieces 19A and 19B reduce (i.e., brake) the vertical vibration of the pipe. Since the vibration of the pipe is reduced, the amount of vibration transmitted from the pipe to the mounted member is reduced by the holder 1.

  Further, in the holder 1, when the pipe 11D held by the clamp portion vibrates in the lateral direction indicated by the arrow 29, the second elastic holding pieces 22A and 22B press the opposite left and right side surfaces of the pipe 11D to the opposite side. The pipe 11D is maintained so as to be positioned at the center of the holding space of the clamp portion 6 in the lateral direction of the arrow 29. The second elastic holding pieces 22A and 22B are elastically held apart from the side walls 14A and 14B by pushing the pipe 11D accommodated in the clamp part 6 back to the center of the accommodation space of the clamp part 6. . Since the second elastic holding pieces 22A and 22B hold the pipe, the pipe does not directly contact the side walls 14A and 14B of the clamp portion even if the pipe vibrates in the lateral direction in the clamp portion 6. The amount of vibration transmitted directly to the clamp portion is reduced, and transmission of vibration between a member to be attached such as a body panel to which the holder is attached and the pipe is reduced. Further, since the elasticity of the second elastic holding pieces 22A and 22B reduces the vibration in the lateral direction of the pipe, the amount of the vibration transmitted from the pipe to the mounted member is reduced by reducing the vibration in the lateral direction of the pipe itself. Decrease.

  When the pipe 11D vibrates in the holding space of the clamp portion 6, the second elastic holding pieces 22A and 22B and the third elastic holding pieces 19A and 19B correspond to the vibration of the pipe 11D as shown in FIG. Then, the base portion 21 is bent in a complicated and many times, and stress is applied to the root portion 21. However, since the reinforcing beam 23 shares the stress, the concentration of stress on the root portion 21 is dispersed and damage to the root portion 21 can be prevented. . Further, the elasticity of the second elastic holding pieces 22A and 22B can be maintained by the reinforcing beam 23 to be sufficiently elastic to reduce the lateral vibration of the pipe 11D, and the vibration of the lateral vibration of the pipe 11D is braked. High effect can be maintained. Further, since the third elastic holding pieces 19A, 19B are connected to the side walls 14A, 14B by the root portion 21 and the reinforcing beam 23 (and the second elastic holding pieces 22A or 22B), the third elastic holding pieces 19A, There is little damage of 19B. Further, in the third elastic holding pieces 19A and 19B, the bead 26 comes into contact with the pipe 11D, and in the second elastic holding pieces 22A and 22B, the protrusion 25 comes into contact with the pipe 11D, so the third elastic holding piece 19A. 19B and the second elastic holding pieces 22A, 22B each have a smaller contact area with the side surface of the pipe, and the amount of vibration of the pipe 11D transmitted to the side walls 14A, 14B of the holder 1 is reduced. The amount of vibration of the pipe 11D transmitted to the body panel 8 (attached member) is reduced.
