Description

  The present invention relates to a clamp used for attaching a pipe made of hard resin, metal or the like to a resin, metal panel or the like.

Conventionally, various clamps have been proposed that are used when pipes made of hard resin or metal are attached to a resin or metal panel.
For example, in Patent Document 1, a fitting portion that is fixed to an attachment target, a substantially U-shaped clamp portion that is connected to the fitting portion, and a central portion of the clamp portion that is inserted from an insertion port. A first receiving portion that receives the first rod-shaped object, a second receiving portion that is provided at the back of the clamp portion and that is inserted from the insertion port of the clamp portion and receives the second rod-shaped object that has passed through the first receiving portion, and a clamp portion An elastic piece extending from the inner wall toward the center of the first receiving portion and elastically deforming to allow the first rod-like object to enter and holding the first rod-like object with the first receiving portion; and from the inner wall of the clamp portion Extending toward the center of the second receiving portion and elastically deforming to allow the second rod-shaped object to enter, holding the second rod-shaped object with the second receiving portion, and moving the first rod-shaped object to the second receiving portion. A clamping technique having a stopper for preventing entry has been proposed.

JP 2004-132394 A (paragraph 0014, FIG. 1 to FIG. 5 etc.)

  Here, in the clamp described in Patent Document 1, since it has the above-described configuration, it extends from the inner wall of the clamp part toward the center part of the second receiving part, and elastically deforms to allow the second rod-like object to enter. The second rod-shaped object is held by the second receiving portion by a stopper that holds the second rod-shaped object by the second receiving portion and prevents the first rod-shaped object from entering the second receiving portion, Since the passage of the first rod-shaped object to the second receiving portion is prevented, the first rod-shaped object does not fall to the second receiving portion side in a state where the clamp is fixed to the attachment target object. Moreover, the installation area of a clamp part can be made small by arrange | positioning a 1st rod-shaped object and a 2nd rod-shaped object in two steps. And since the insertion direction to the clamp part of a 1st rod-shaped object and a 2nd rod-shaped object becomes the same, it describes that it is the technique which is easy to work and can reduce work man-hours.

  However, in the technique described in Patent Document 1 described above, the first rod-shaped object provided at the center portion of the substantially U-shaped clamp portion and inserted from the insertion port has the tip surface of the outer diameter of the first rod-shaped object. A first receiving part that is held by an arc surface having substantially the same radius of curvature, and a second rod-like object that is provided at the back of the clamp part and is inserted from the insertion port of the clamp part and passes through the first receiving part, A second receiving portion recessed in an arc shape having substantially the same radius of curvature as the outer diameter of the second rod-shaped object is provided in series. Therefore, the holding force for holding the first bar and the second bar of the first receiving part and the second receiving part is substantially the same as the outer diameter of the first bar and the second bar. There is a problem that it is weak because of having a radius of curvature. Therefore, after attaching a plurality of clamps to a predetermined position of a rod-shaped object to make an assembly of the clamp and the rod-shaped object, holding the clamp when transporting this assembled part or attaching it to a resin, metal panel, etc. Since the force is weak, the clamp is displaced from a predetermined position, and there is a problem that labor and waste of man-hours that must be corrected each time occur.

  In addition, since a plurality of rod-shaped objects are attached in series to the substantially U-shaped clamp portion, the holding force cannot be increased for all the rod-shaped objects, and between any one of the rod-shaped objects and the receiving portion. There is a problem of looseness. For this reason, for example, when a clamp and a rod-like assembled part are attached to an automobile panel or the like, there is a problem that chatter noise is likely to be generated due to vibration of the automobile because there is a backlash between the rod-like object and the receiving portion.

  Therefore, the present invention has been made to solve the above-described problems, and after a plurality of clamps are attached to predetermined positions of a bar-like object to form an assembly part of the clamp and the bar-like object, the assembled part is conveyed. When attaching to a resin or metal panel, etc., the clamp can be easily removed from a predetermined position of the rod-shaped object, so that it can be easily attached to a resin, metal panel, etc. An object of the present invention is to provide a clamp that can be attached and can eliminate chatter noise caused by vibration.

  In order to achieve the above object, a clamp according to claim 1 includes a clamp body having a mounting leg portion to be attached to an attachment target, a pair of wall portions provided on the clamp body and facing each other, and the pair of walls. A receiving portion that is provided on the clamp body between the two portions and receives a rod-like object inserted between the pair of wall portions, and a central portion of the receiving portion that is provided on at least one wall portion of the pair of wall portions An elastic piece that extends toward the side and elastically deforms when the rod-shaped object is inserted, allows the rod-shaped object to be inserted, and cooperates with a receiving portion after insertion to hold the rod-shaped object; When the rod-shaped object is inserted between the opening end portions of the section and the pair of wall sections and the rod-shaped object is inserted into the receiving section, at least one of them is elastically deformed to press and sandwich the rod-shaped object. A pair of clamping walls to prevent axial displacement of the stick-shaped material, characterized by comprising a.

  A clamp according to claim 2 is the clamp according to claim 1, wherein a slit is provided between the clamping wall and the wall portion.

  The clamp according to claim 3 is the clamp according to claim 1 or 2, wherein the pair of clamping walls are provided on an inner side than a diameter of the rod-like object inserted into the receiving portion. It is characterized by.

  According to a fourth aspect of the present invention, in the clamp according to any one of the first to third aspects, the pair of sandwiching walls press a substantially diameter portion of the rod-like object inserted into the receiving portion. It is characterized by being held between.

  And the clamp which concerns on Claim 5 is a clamp in any one of Claim 1 thru | or 4, Comprising: The structure of the said pair of wall part, the said receiving part, the said elastic piece, and said pair of clamping wall is at least 2 It is characterized by having more than two.

  In the clamp according to claim 1, at least one wall portion of the pair of wall portions is provided by providing a pair of sandwiching walls at least one of which is elastically deformed between each opening end portion of the receiving portion and the pair of wall portions. When the rod-shaped object is inserted into the receiving part while elastically deforming the elastic piece provided on the bar, the rod-shaped object is accommodated in the receiving part by elastically deforming at least one of the pair of sandwiching walls, and elastic deformation of the sandwiching wall is performed. The holding wall presses and holds the rod-shaped object by the repulsive force. This pressing can prevent the axial displacement of the rod-shaped object. In this way, after attaching a plurality of clamps to a predetermined position of the rod-like object in the sub assembly line to form a clamp and rod-like assembly part, this assembly part is attached to the resin, metal panel, etc. in the main assembly line When attaching this assembled part to resin, metal panels, etc. in the process of transporting to the main assembly line, the clamp is displaced from the predetermined position due to weak holding power of the clamp, and must be corrected each time Therefore, it is possible to eliminate the labor and waste of man-hours and provide a stable assembly.

  Further, since the holding wall presses and holds the rod-like object by the repulsive force of the elastic deformation of the holding wall, it is possible to eliminate the play generated between the receiving portion and the rod-like object. Therefore, for example, when a clamp and a rod-like assembly are attached to an automobile panel or the like, chatter noise caused by the vibration of the automobile generated due to the backlash between the rod-like object and the receiving portion can be eliminated. Moreover, since the elastic piece holds the rod-shaped object even if the rod-shaped object is about to be detached from the receiving part due to vibration or external force, it is possible to prevent the rod-shaped object from being detached from the receiving part.

  In the clamp according to claim 2, since the slit is provided between the holding wall and the wall portion, the holding wall can be elastically deformed with a simple structure. Further, it is not necessary to add an extra part such as a spring instead of elastically deforming the holding wall.

  In the clamp according to claim 3, the pair of clamping walls are provided on the inner side of the diameter of the rod-like object inserted into the receiving part, so that when the rod-like object is inserted into the receiving part, the clamping wall is It is elastically deformed, and the pressing force, which is the repulsive force, reliably presses the rod-like object, and the clamp can be prevented from shifting from a predetermined position because the holding force of the clamp is weak.

  In the clamp according to claim 4, the pair of sandwiching walls press and sandwich the substantially diameter portion of the rod-like object inserted into the receiving portion, so that the pressing force of each sandwiching wall is dispersed. Since the rod-like objects are pressed against each other without any problems, the maximum pressing force can be drawn, and the clamp can be prevented from being displaced from a predetermined position because the holding force of the clamp is weak.

  In the clamp according to claim 5, by providing at least two or more configurations of the pair of wall portions, the receiving portion, the elastic piece, and the pair of clamping walls, a plurality of rod-shaped objects can be locked with one clamp. In addition, it eliminates the labor and waste of man-hours that a single bar is displaced from the clamp and must be corrected each time, and a plurality of clamps are attached to predetermined positions of a plurality of bars. It is also possible to provide a stable assembly of clamps and rods.

Thus, when the first pipe 15, the second pipe 17, and the third pipe 19 are attached to the clamp 1 and when the clamp 1 is attached to the attachment holes 5 and 6 of the panel 4 of an automobile or the like, High rigidity is demonstrated.

  A first wall portion 35 having the same width as the depth of the first rib 10 is extended upward from the upper end portion of the first rib 10. Further, from the upper surface of the second connecting rib 25 provided between the first receiving portion 16 and the second receiving portion 18, the depth width of the first wall portion 35 is the same as that of the first wall portion 35.

The heights from the base 3 to the tip of the first wall 35, the second wall 36, the third wall 37, and the fourth wall 38 are substantially the same.

  Further, from the upper end side of the first wall portion 35 and the second wall portion 36 erected on both sides of the first receiving portion 16 to which the first pipe 15 is mounted, toward the central portion of the first receiving portion 16, The first wall 35 includes a first slope 39 and a first elastic piece 40 having the same width as the first wall 35 extends. The second wall 36 includes a second slope 41 and a second slope. A second elastic piece 42 having the same width as the wall 36 is extended. At this time, the upper end portion of the first wall portion 35 and the first inclined surface 39, and the upper end portion of the second wall portion 36 and the second inclined surface 41 are connected by an arc, so that the first pipe 15 is connected to the first inclined surface. 39 and the second slope 41 can be smoothly guided. The first elastic piece 40 and the second elastic piece 42 make a pair, and the separation distance between the first slope 39 of the first elastic piece 40 and the second slope 41 of the second elastic piece 42 is the first piping. It is narrower than the outer diameter size of 15. Therefore, when the first pipe 15 passes between the first inclined surface 39 and the second inclined surface 41 in order to attach the first pipe 15 to the first receiving portion 16, the first elastic piece 40 has the first wall portion 35. The second elastic piece 42 is allowed to pass through the first pipe 15 by being elastically deformed toward the second wall portion 36.

  Furthermore, the front end surface of the first elastic piece 40 is a first pipe holding surface 43 having a radius of curvature substantially the same as the outer diameter dimension of the first pipe 15, and the first pipe 15 is attached to the first receiving portion 16.

The first pipe 15 is prevented from coming off due to external force, vibration, or the like in cooperation with the first pipe holding surface 43 in contact with the surface. Moreover, since the 1st slope 39 and the 1st piping holding surface 43 and the 2nd slope 41 and the 2nd piping holding surface 44 are connected by the circular arc, the 1st piping 15 is smoothly connected to the 1st receiving part 16. The first elastic piece 40 and the second elastic piece 42 are immediately returned to a predetermined position by the repulsive force of these elastic deformations to prevent the first pipe 15 from coming off.

  Similarly, from the upper end side of the 2nd wall part 36 and the 3rd wall part 37 which were standingly arranged by the both sides of the 2nd receiving part 18 with which the 2nd piping 17 is mounted, toward the center part of the 2nd receiving part 18, A third slope 45 is provided from the second wall 36 and a third elastic piece 46 having the same width as the second wall 36 is extended. A fourth slope 47 is provided from the third wall 37 and the third slope 46 is provided. A fourth elastic piece 48 having the same width as the three wall portions 37 is extended. At this time, since the upper end portion of the second wall portion 36 and the third inclined surface 45 and the upper end portion of the third wall portion 37 and the fourth inclined surface 47 are connected by an arc, the second pipe 17 is connected to the third inclined surface. 45 and the fourth slope 47 can be guided smoothly. The third elastic piece 46 and the fourth elastic piece 48 form a pair, and the separation distance between the third inclined surface 45 of the third elastic piece 46 and the fourth inclined surface 47 of the fourth elastic piece 48 is the second piping. It is narrower than the outer diameter of 17. Therefore, when the second pipe 17 passes between the third slope 45 and the fourth slope 47 in order to attach the second pipe 17 to the second receiving portion 18, the third elastic piece 46 is in the second wall portion 36. The fourth elastic piece 48 is elastically deformed toward the third wall portion 37 to allow passage of the second pipe 17.

  Further, the distal end surface of the third elastic piece 46 is a third pipe holding surface 49 having a radius of curvature substantially the same as the outer diameter dimension of the second pipe 17, and the second pipe 17 is connected to the second receiving portion 18. When it is mounted, it comes into surface contact to prevent the second pipe 17 from coming off due to external force or vibration. Similarly, the tip surface of the fourth elastic piece 48 is a third pipe holding surface 49 having a radius of curvature substantially the same as the outer diameter of the second pipe 17, and the second pipe 17 is the second receiving portion 18. The second pipe 17 is prevented from coming off due to an external force, vibration, or the like in cooperation with the third pipe holding surface 49 in surface contact with the second pipe 17. Moreover, since the 3rd slope 45 and the 3rd piping holding surface 49 and the 4th slope 47 and the 3rd piping holding surface 49 are connected by the circular arc, the 2nd piping 17 is smoothly connected to the 2nd receiving part 18. The third elastic piece 46 and the fourth elastic piece 48 are immediately returned to a predetermined position by the repulsive force of these elastic deformations to prevent the second pipe 17 from coming off.

And the 3rd wall part 37 and the 4th wall part 38 are standingly arranged in the both sides of the 3rd receiving part 20 which mounts the 3rd piping 19, but the diameter of the 3rd piping 19 to be mounted is thin, In order to minimize the installation area, one third wall portion 37 has no elastic piece as the arc-shaped wall surface 51 having a large radius, the other fourth wall portion 38 is provided with a fifth inclined surface 52 and the fourth wall portion. The fifth elastic piece 53 having the same width as that of the third elastic member 38 extends from the upper end side of the fourth wall portion 38 toward the central portion of the third receiving portion 20. The fifth slope 52 provided on the fifth elastic piece 53 is connected to the tip of the fourth wall 38 by an arc, and smoothly guides the third pipe 19 to the wall 51 and the fifth slope 52. Make it possible. The separation distance between the wall surface 51 of the third wall portion 37 and the fifth inclined surface 52 of the fifth elastic piece 53 is narrower than the outer diameter of the third pipe 19. Therefore, when the third pipe 19 passes between the wall surface 51 and the fifth inclined surface 52 in order to attach the third pipe 19 to the third receiving part 20, the fifth elastic piece 53 faces the fourth wall part 38. The third pipe 19 is allowed to pass through by being elastically deformed.
Further, the tip surface of the fifth elastic piece 53 is a fifth pipe holding surface 54 having a radius of curvature substantially the same as the outer diameter dimension of the third pipe 19, and the third pipe 19 is connected to the third receiving portion 20. When it is mounted, it comes into surface contact to prevent the third pipe 19 from coming off due to external force or vibration. Further, since the fifth slope 52 and the fifth pipe holding surface 54 are connected by an arc, the third pipe 19 can be smoothly guided to the third receiving portion 20 and the fifth elastic piece 53 is provided. The third pipe 19 is prevented from coming off by immediately returning to a predetermined position by the repulsive force of the elastic deformation of the fifth elastic piece 53.

  A first holding wall 55 having the same width as the first receiving portion 16 is formed from the first opening end portion 21 which is the right end portion of the arc-shaped first receiving portion 16 to which the first pipe 15 is attached. It extends upward. A second holding wall 56 having the same width as the first receiving portion 16 extends upward from the second opening end portion 23 which is the left end portion of the arc-shaped first receiving portion 16. The first clamping wall 55 and the second clamping wall 56 are paired. As shown in FIG. 4, the opposing distance is set shorter than the diameter of the first pipe 15 attached to the first receiving portion 16. Yes. Therefore, normally, the first piping 15 cannot be inserted between the first clamping wall 55 and the second clamping wall 56. Therefore, a first slit 57 is provided between the first clamping wall 55 and the first wall 35, By providing the second slit 58 between the second clamping wall 56 and the second wall portion 36, the first clamping wall 55 and the second clamping wall 56 can be elastically deformed toward the first slit 57 and the second slit 58. Thus, insertion of the first pipe 15 is allowed between the first holding wall 55 and the second holding wall 56, the first pipe 15 is mounted on the first receiving portion 16, and the first holding wall 55 and the second holding wall A wall 56 sandwiches the first pipe 15.

  At this time, as described above, the first pipe holding surface 43 and the second pipe holding surface 44 are in surface contact with the first pipe 15 to prevent the first pipe 15 from coming off due to external force or vibration. Further, the clamping force with which the first clamping wall 55 and the second clamping wall 56 clamp the first pipe 15 is such that when the first pipe 15 is inserted between the first clamping wall 55 and the second clamping wall 56, The first holding wall 55 and the second holding wall 56 are generated by a repulsive force that is elastically deformed. This clamping force can prevent the clamp 1 from shifting in the axial direction of the first pipe 15 and eliminate chattering with the first receiving portion 16 of the first pipe 15 to eliminate chatter noise caused by vibration. it can. Moreover, since the front-end | tip of the 1st clamping wall 55 and the 2nd clamping wall 56 is chamfered by circular arc shape, it enables it to guide the 1st piping 15 to the 1st receiving part 16 smoothly. In addition, the 1st clamping wall 55 and the 2nd clamping wall 56 may eliminate the 1st slit 57 and the 2nd slit 58, and may just make it a rib shape.

  Similarly, a third holding wall 59 having the same width as the second receiving portion 18 is formed from the third opening end portion 24 which is the right end portion of the arc-shaped second receiving portion 18 to which the second pipe 17 is attached. Is extended upward. A fourth holding wall 60 having the same width as the second receiving portion 18 extends upward from the fourth opening end portion 26 which is the left end portion of the arc-shaped second receiving portion 18. The third clamping wall 59 and the fourth clamping wall 60 are paired, and as shown in FIG. 4, the opposing distance is set shorter than the diameter of the second pipe 17 attached to the second receiving portion 18. Yes. Therefore, normally, the second piping 17 cannot be inserted between the third clamping wall 59 and the fourth clamping wall 60. Therefore, a third slit 61 is provided between the third clamping wall 59 and the second wall portion 36. By providing the fourth slit 62 between the fourth clamping wall 60 and the third wall portion 37, the third clamping wall 59 and the fourth clamping wall 60 can be elastically deformed toward the third slit 61 and the fourth slit 62 side. Thus, the second piping 17 is allowed to be inserted between the third clamping wall 59 and the fourth clamping wall 60, the second piping 17 is attached to the second receiving portion 18, and the third clamping wall 59 and the fourth clamping wall are inserted. The wall 60 sandwiches the second pipe 17.

  At this time, as described above, the third pipe holding surface 49 and the fourth pipe holding surface 50 are in surface contact with the second pipe 17 to prevent the second pipe 17 from coming off due to external force or vibration. Further, the clamping force with which the third clamping wall 59 and the fourth clamping wall 60 clamp the second piping 17 is such that when the second piping 17 is inserted between the third clamping wall 59 and the fourth clamping wall 60, The third clamping wall 59 and the fourth clamping wall 60 are generated by a repulsive force that is elastically deformed. This clamping force can prevent the clamp 1 from shifting in the axial direction of the second pipe 17 and eliminate chattering with the second receiving portion 18 of the second pipe 17 to eliminate chatter noise caused by vibration. it can. Moreover, since the tips of the third clamping wall 59 and the fourth clamping wall 60 are chamfered in an arc shape, the second piping 17 can be smoothly guided to the second receiving portion 18. The third sandwiching wall 59 and the fourth sandwiching wall 60 may be simply formed in a rib shape without the third slit 61 and the fourth slit 62.

  And from the 5th opening edge part 27 which is the right-side edge part of the circular arc-shaped 3rd receiving part 20 with which the 3rd piping 19 is mounted | worn, the diameter of the 3rd piping 19 with which the mounting | wearing is thin is mentioned above. In order to minimize the installation area, a fifth holding wall 63 having the same width as the third receiving portion 20 and inclined inward is formed integrally with the third wall portion 37. Further, from the fourth opening end portion 26 which is the left end portion of the arc-shaped second receiving portion 18, the sixth holding wall 64 having the same width as the third receiving portion 20 extends upward while being inclined outward. Has been issued. The fifth clamping wall 63 and the sixth clamping wall 64 are paired. As shown in FIG. 4, the opposing distance is set shorter than the diameter of the third pipe 19 attached to the third receiving portion 20. Yes. Therefore, normally, the third pipe 19 cannot be inserted between the fifth clamping wall 63 and the sixth clamping wall 64, so a fifth slit 65 is provided between the sixth clamping wall 64 and the fourth wall portion 38. As a result, the sixth clamping wall 64 can be elastically deformed toward the fifth slit 65, and the third pipe 19 is allowed to be inserted between the fifth clamping wall 63 and the sixth clamping wall 64, and the third pipe 19 is connected to the third pipe 19. The fifth holding wall 63 and the sixth holding wall 64 are attached to the receiving portion 20 and hold the third pipe 19.

  At this time, as described above, the fifth pipe holding surface 54 is in surface contact with the third pipe 19 to prevent the third pipe 19 from coming off due to external force or vibration. Further, the clamping force with which the fifth clamping wall 63 and the sixth clamping wall 64 clamp the third pipe 19 is such that when the third pipe 19 is inserted between the fifth clamping wall 63 and the sixth clamping wall 64, The sixth clamping wall 64 is generated by a repulsive force that is elastically deformed. This clamping force can prevent the clamp 1 from shifting in the axial direction of the third pipe 19 and eliminate chattering with the third receiving portion 20 of the third pipe 19 to eliminate chatter noise caused by vibration. it can. Further, since the tip of the sixth clamping wall 64 is chamfered in an arc shape, the third pipe 19 can be smoothly guided to the third receiving portion 20. Note that the sixth sandwiching wall 64 may have a rib shape without the fifth slit 65. And the clamp 1 comprised in this way is integrally shape | molded by the polyacetal (POM) etc.

  Here, FIG. 4 will be described. FIG. 4 is an explanatory diagram for explaining the relationship between the piping and the receiving portion. In the example of this embodiment shown in Table 66 of FIG. 4, the first pipe 15 having a diameter of 8.00 mm is accommodated with respect to the A part, and the radius of the arc of the receiving part 16 that receives the first pipe 15 is 4.05 mm. The distance between the first clamping wall 55 and the second clamping wall 56 that clamp the first pipe 15 is set to 7.74 mm. Therefore, as shown in the enlarged view of the portion A, the receiving portion 16 in which the first pipe 15 is not accommodated, the first holding wall 55, the second holding wall 56, the first pipe holding surface 43, and the second pipe holding surface 44. When the first pipe 15 indicated by the dotted line is overlapped in this state, a portion overlapping the first pipe 15 is generated at the first holding wall 55 and the second holding wall 56. Therefore, when the first pipe 15 is accommodated, the first clamping wall 55 and the second clamping wall 56 are elastically deformed outward by the overlapping amount. The repulsive force of the second clamping wall 56 presses the first pipe 15 to hold the first pipe 15 strongly, thereby eliminating chatter noise caused by vibration and preventing the first pipe 15 from shifting in the axial direction. At this time, the first piping holding surface 43 and the second piping holding surface 44 prevent the external force applied to the first piping 15 from being detached from the portion A shown in FIG.

  Similarly, the second pipe 17 having a diameter of 6.35 mm is accommodated with respect to the B part, and the radius of the arc of the receiving part 18 that receives the second pipe 17 is set to 3.22 mm so as to sandwich the second pipe 17. The distance between the third clamping wall 59 and the fourth clamping wall 60 is set to 6.09 mm. For this purpose, as shown in the enlarged view of part B, the receiving part 18 in which the second pipe 17 is not accommodated, the third clamping wall 59, the fourth clamping wall 60, the third pipe holding surface 49, and the fourth pipe holding surface 50. When the second pipe 17 indicated by the dotted line is overlapped with the state of FIG. 8, a portion overlapping the second pipe 17 is generated at the third holding wall 59 and the fourth holding wall 60. Therefore, when the second pipe 17 is stored, the third clamping wall 59 and the fourth clamping wall 60 are elastically deformed outward by the overlapping amount. The repulsive force of the 4th clamping wall 60 presses the 2nd piping 17, hold | maintains the 2nd piping 17 strongly, eliminates the chatter noise by vibration, and prevents the shift | offset | difference of the 2nd piping 17 in the axial direction. At this time, the third pipe holding surface 49 and the fourth pipe holding surface 50 prevent the external force applied to the second pipe 17 from coming off from the portion B shown in FIG.

  Similarly, the third pipe 19 having a diameter of 4.80 mm is accommodated in the part C, and the radius of the arc of the receiving part 20 that receives the third pipe 19 is set to 2.44 mm. The distance between the fifth clamping wall 63 and the sixth clamping wall 64 to be clamped is set to 4.61 mm. Therefore, as shown in the enlarged view of the portion C, the states of the receiving portion 20, the fifth holding wall 63, the sixth holding wall 64, and the fifth pipe holding surface 54 in which the third pipe 19 is not stored are indicated by dotted lines. When the third piping 19 is overlapped, a portion that overlaps the third piping 19 is generated at the fifth clamping wall 63 and the sixth clamping wall 64. Therefore, when the third pipe 19 is accommodated, the fifth clamping wall 63 and the sixth clamping wall 64 are elastically deformed outward by the overlapping amount, so that the fifth clamping wall 63 generated at that time The repulsive force of the sixth clamping wall 64 presses the third pipe 19 to hold the third pipe 19 strongly, thereby eliminating chatter noise caused by vibration and preventing the third pipe 19 from shifting in the axial direction. At this time, the fifth pipe holding surface 54 prevents the external force applied to the third pipe 19 from being detached from the portion C shown in FIG.

Subsequently, an attachment method and its characteristics when the first pipe 15, the second pipe 17, and the third pipe 19 are attached to the clamp 1 configured as described above and attached to a panel 4 such as a car body of an automobile. This will be described with reference to FIGS.
Here, FIGS. 5 to 8 are explanatory views for explaining a process of attaching the first pipe, the second pipe, and the third pipe to the clamp, and FIGS. 9 to 11 are the first pipe, the second pipe, and the third pipe. FIG. 12 is an explanatory diagram illustrating a process of attaching a clamp with a pipe attached to the panel, FIG. 12 is an explanatory diagram showing a state where the clamp with the pipe attached is attached to the panel, and FIG. 13 is an insertion distance of the third pipe to the clamp. It is explanatory drawing explaining an insertion load curve.

First, based on FIG. 5 thru | or FIG. 8, the process for manufacturing the assembled component which attached the 1st piping 15, the 2nd piping 17, and the 3rd piping 19 to the clamp 1 is demonstrated. In order to manufacture the assembled part, the clamp 1 is fixed to an assembly jig (not shown) in the state shown in FIG.
First, the process of attaching the first pipe 15 to the clamp 1 will be described. The first pipe 15 is moved in the direction of arrow A shown in FIG. 5 and pressed against the first slope 39 of the first elastic piece 40 and the second slope 41 of the second elastic piece 42. At this time, the upper end portion of the first wall portion 35 and the first inclined surface 39, and the upper end portion of the second wall portion 36 and the second inclined surface 41 are connected by an arc and the first inclined surface of the first elastic piece 40. 39 and the second slope 41 of the second elastic piece 42 extend toward the center of the first receiving portion 16, so that the first pipe 15 is smoothly guided to the first slope 39 and the second slope 41. Make it possible. Then, the insertion of the first pipe 15 in the direction of arrow A is started.

  When the first pipe 15 is inserted in the direction of arrow A, it is pressed by the first pipe 15 and the first elastic piece 40 is elastically deformed toward the first wall 35 and the second elastic piece 42 is moved toward the second wall 36. Elastically deforms. At the position of the first pipe 15 shown in FIG. 6 where the first elastic piece 40 and the second elastic piece 42 are parallel and moved in the direction of the arrow A for a while, the first elastic piece 40 and the second elastic piece 42 are elastically deformed. The peak of the insertion load, which is the repulsive force, is over.

  Further, by inserting the first pipe 15 in the direction of arrow A, as shown in FIG. 7, the diameter of the first pipe 15 is an arc formed by the first slope 39 and the first pipe holding surface 43, When it comes to a position beyond the arc formed by the second slope 41 and the second pipe holding surface 44, the first elastic piece 40 and the second elastic piece 42 immediately return to a predetermined position by the repulsive force of their own elastic deformation. In addition, an arc formed by the first slope 39 and the first pipe holding surface 43 of the first elastic piece 40 and the second slope 41 and the second pipe holding surface 44 of the second elastic piece 42 connects the first pipe 15 to the first. The first receiving portion 16 is attached to the first receiving portion 16 while being press-fitted between the first holding wall 55 and the second holding wall 56.

  As a result, as shown in FIG. 8, the first pipe 15 is attached to the first receiving portion 16, and the first holding wall 55 and the second holding wall 56 hold the first pipe 15 so that the shaft of the first pipe 15 is provided. The first pipe holding surface 43 and the second pipe holding surface 44 prevent the first pipe 15 from being detached due to an external force.

  Next, the process of mounting the second pipe 17 to the clamp 1 will be described. The second pipe 17 is different from the first pipe 15 only in the points that are different, and the other steps are exactly the same as those of the first pipe 15. Therefore, explanation is omitted here.

  Next, the process of attaching the third pipe 19 to the clamp 1 will be described. The third pipe 19 is moved in the direction of arrow A shown in FIG. 5 and pressed against the arc-shaped wall surface 51 having a large radius formed on the third wall portion 37 and the fifth inclined surface 52 of the fifth elastic piece 53. At this time, the upper end portion of the fourth wall portion 38 and the fifth inclined surface 52 are connected by an arc, and the fifth inclined surface 52 of the fifth elastic piece 53 extends toward the central portion of the third receiving portion 20. Therefore, the third pipe 19 can be smoothly guided to the wall surface 51 and the fifth slope 52. Then, the insertion of the third pipe 19 in the direction of arrow A is started.

  When the third pipe 19 is inserted in the direction of arrow A, it is pressed by the third pipe 19 and the fifth elastic piece 53 is elastically deformed toward the fourth wall portion 38 side. At the position of the third pipe 19 shown in FIG. 6 where the wall surface 51 and the fifth elastic piece 53 are substantially parallel and moved in the direction of the arrow A for a while, the insertion load, which is the repulsive force of the elastic deformation of the fifth elastic piece 53, is reduced. The peak is over.

  Further, by inserting the third pipe 19 in the direction of arrow A, the diameter of the third pipe 19 exceeds the arc formed by the fifth slope 52 and the fifth pipe holding surface 54 as shown in FIG. When it reaches the position, the fifth elastic piece 53 immediately returns to a predetermined position by the repulsive force of its own elastic deformation, and is formed by the fifth inclined surface 52 of the fifth elastic piece 53 and the fifth pipe holding surface 54. The arc acts to attach the third pipe 19 to the third receiving portion 20 while press-fitting the third pipe 19 between the fifth clamping wall 63 and the sixth clamping wall 64.

As a result, as shown in FIG. 8, the third pipe 19 is attached to the third receiving portion 20, and the fifth holding wall 63 and the sixth holding wall 64 hold the third pipe 19, and the axial direction of the third pipe 19. The fifth pipe holding surface 54 prevents the third pipe 19 from coming off due to an external force.
In this way, the assembled part shown in FIG. 8 in which the first pipe 15, the second pipe 17, and the third pipe 19 are mounted on the clamp 1 is manufactured, and the first pipe 15, the second pipe 17, and the third pipe 19 are clamped. 1 is removed from an assembly jig (not shown).

Next, a process of attaching the assembled part in which the first pipe 15, the second pipe 17, and the third pipe 19 are attached to the clamp 1 to the panel 4 will be described with reference to FIGS. 9 to 12.
FIG. 9 shows a state in which an assembled part in which the first pipe 15, the second pipe 17, and the third pipe 19 are attached to the clamp 1 is removed from an assembly jig (not shown) based on FIGS. 5 to 8. . In the process of storing this state and transporting it to the main assembly line, the clamp 1 is shown in FIG. 9 from predetermined positions of the first pipe 15, the second pipe 17, and the third pipe 19 due to careless handling by the operator. Although there is a risk of shifting in the directions of arrows B and C, the first piping 15 is pressed and clamped by the first clamping wall 55 and the second clamping wall 56, and the second piping 17 is clamped by the third clamping wall 59 and the fourth. Since the clamping wall 60 is pressed and clamped, and the third piping 19 is pressed and clamped by the fifth clamping wall 63 and the sixth clamping wall 64, there is no deviation in the directions of arrows B and C.

FIG. 10 shows a mounting leg 7 provided below the base 3 of the clamp 1 in an assembled part in which the first pipe 15, the second pipe 17, and the third pipe 19 are attached to the clamp 1 shown in FIG. The state which attaches to the attachment holes 5 and 6 drilled in the panel 4 of resin, a metal, etc. with which it comprises is shown. In this state, the clamps 1 are pressed in the direction of the arrow D by fitting the mounting legs 7 provided below the bases 3 of the clamps 1 to the mounting holes 5 and 6 drilled in the panel 4. At this time, the first elastic locking claw 8 and the second elastic locking claw 9 (see FIG. 3) provided on the mounting leg portion 7 are elastically applied to the inside of the mounting leg portion 7 by pressing of the wall surfaces of the mounting holes 5 and 6. Deform.
Also in the process of FIG. 10, the clamp 1 may be displaced from predetermined positions of the first pipe 15, the second pipe 17, and the third pipe 19 in the directions of arrows E and F shown in FIG. However, the first holding wall 55 and the second holding wall 56 press and hold the first pipe 15 and the third holding wall 59 and the fourth holding wall 60 press and hold the second pipe 17. Since the third holding wall 63 and the sixth holding wall 64 are pressed and held in the third pipe 19, the third pipe 19 is not displaced in the directions of arrows E and F.

  Then, as shown in FIG. 11, when the base 3 of each clamp 1 comes into contact with the surface of the panel 4, the first elasticity that has been elastically deformed inside the mounting leg 7 due to the pressing of the wall surface of the mounting holes 5, 6. The locking claw 8 and the second elastic locking claw 9 (see FIG. 3) protrude outside the mounting leg 7 and are locked to the back surface of the panel 4.

  In this way, the work of assembling the assembled part in which the first pipe 15, the second pipe 17, and the third pipe 19 are attached to the clamp 1 to the panel 4 is completed. 12 shows that in the work process of FIG. 11, when the base 3 of the clamp 1 comes into contact with the surface of the panel 4, it is elastically deformed to the inside of the mounting leg 7 by pressing of the wall surfaces of the mounting holes 5 and 6. The first elastic locking claw 8 and the second elastic locking claw 9 are shown protruding from the outside of the mounting leg 7 and locked to the back surface of the panel 4. As described above, when the first elastic locking claw 8 and the second elastic locking claw 9 of the mounting leg 7 of the clamp 1 are locked to the panel 4, the first elastic locking claw 8 and the second elastic locking claw 8. The clamp 1 cannot be removed from the panel 4 unless the claw 9 is mechanically elastically deformed inside the mounting leg portion 7 or the first elastic locking claw 8 and the second elastic locking claw 9 are destroyed.

Next, in the operation steps of FIGS. 5 to 8, the actual insertion load of the pipe and the holding force in the axial direction of the pipe are determined according to the third pipe 19 (diameter: 4.80 mm, arc of the third receiving portion 20). ): 2.44 mm, opposing distance between the fifth clamping wall 63 and the sixth clamping wall 64: 4.61 mm, length of the fifth clamping wall 63 and the sixth clamping wall 64: 14.4 mm) The results will be described based on the graph 67 of FIG. Incidentally, the manufacturer's requirements for using this clamp 1 are: piping insertion load: 80 (N) or less, piping holding force: 98 (N) or more, piping axial holding force: 9.8 (N ) That's it.
A graph 67 shown in FIG. 13 is an insertion distance vs. insertion load curve of the third pipe 19, and the third pipe 19 is connected to the wall surface 51 and the fifth slope 52 from the G portion, and the third pipe 19 is the fifth clamping wall. 63 is a curve showing an insertion load with respect to an insertion distance into which the third pipe 19 is inserted up to a K portion sandwiched between 63 and a sixth sandwiching wall 64 and attached to the third receiving portion 20.

  G part is a point which the 3rd piping 19 contact | abuts to the wall surface 51 and the 5th slope 52 as mentioned above, and becomes an origin of insertion distance and insertion load. The insertion of the third pipe 19 is started from here, and the fifth slope 52 is elastically deformed in proportion to the insertion distance of the third pipe 19 toward the fourth wall portion 38 by the third pipe 19, so that the repulsive force is inserted. The load value increases.

  The H portion where the third pipe 19 is inserted by about 2.5 mm from the G portion is that the wall surface 51 and the fifth inclined surface 52 are substantially parallel by the distance of the diameter 69 of the third pipe 19. Therefore, since the amount of elastic deformation of the fifth slope 52 toward the fourth wall portion 38 is constant from now on, the insertion load value of the repulsive force decreases due to the moment. Since the arc shape still remains on the wall surface 51 between the point from the point G to the point about 3.2 mm (0.7 mm), the balance between the insertion distance and the insertion load of the repulsive force is maintained. Is almost flat. Therefore, the peak 41.25 (N) of the insertion load is measured during this period. When the point from the G portion to about 3.2 mm is passed, the wall surface 51 and the fifth inclined surface 52 become completely parallel at a distance of the diameter 69 of the third pipe 19, so that the fifth inclined surface 52 becomes the fourth wall portion 38. The amount of elastic deformation to the side becomes completely constant, and the value of the insertion load of the repulsive force continues to decrease to the J portion where the third pipe 19 is inserted due to the moment.

  The point where the third pipe 19 is inserted by about 6.2 mm from the G part has a point where the diameter 69 of the third pipe 19 exceeds the circular chamfer 68 formed by the fifth slope 52 and the fifth pipe holding surface 54. It is. As shown in the lower part of FIG. 13, when the arcuate chamfered portion 68 formed by the fifth inclined surface 52 and the fifth pipe holding surface 54 is positioned beyond the diameter 69 of the third pipe 19, the fifth The elastic piece 53 immediately returns to a predetermined position by the repulsive force of its own elastic deformation, and at the same time, an arcuate chamfered portion 68 formed by the fifth inclined surface 52 of the fifth elastic piece 53 and the fifth pipe holding surface 54 is formed. The third pipe 19 is attached to the third receiving portion 20 while being press-fitted between the fifth clamping wall 63 and the sixth clamping wall 64. Therefore, the insertion load becomes 0 (N), which continues to the K portion where the third pipe 19 is sandwiched between the fifth sandwiching wall 63 and the sixth sandwiching wall 64 and attached to the third receiving portion 20.

K part is a point by which the 3rd piping 19 is clamped by the 5th clamping wall 63 and the 6th clamping wall 64 as above-mentioned, and is attached to the 3rd receiving part 20, and the 3rd piping 19 from G part is about 7 .9mm inserted position.
Thus, when the holding force of the 3rd piping 19 clamped by the 5th clamping wall 63 and the 6th clamping wall 64 and mounted | worn with the 3rd receiving part 20 was measured, it was 25-30 (N). For reference, when the fifth clamping wall 63 and the sixth clamping wall 64 are not provided, the length is 5 to 7 (N). Further, the holding force of the third pipe 19 does not come off because the fifth pipe holding surface 54 moves in the direction in which the interval between the wall surface 51 and the fifth inclined surface 52 is narrowed when pulled in the direction of removing the third pipe 19. (N) It confirmed that it was more than.
Summarizing the above measurement results, the manufacturer's required standards are: pipe insertion load: 80 (N) or less, pipe holding force: 98 (N) or more, pipe axial holding force: 9.8 (N ) Above, the measurement results are as follows: pipe insertion load: 41.25 (N), pipe holding force: 98 (N) or higher, pipe axial holding power: 25-30 (N Therefore, the requirements of the manufacturer using this clamp 1 are fully satisfied.

  As described above in detail, in the clamp 1 according to the first embodiment, for example, the fifth opening end portion 27, the sixth opening end portion 29, the pair of third wall portions 37 of the third receiving portion 20, the first By providing a pair of fifth clamping wall 63 and sixth clamping wall 64, at least one of which is elastically deformed between the four wall portions 38, at least one of the pair of third wall portion 37 and fourth wall portion 38 is provided. When the third pipe 19 is inserted into the third receiving portion 20 while elastically deforming the fifth elastic piece 53 provided on the fourth wall portion 38, at least one of the pair of fifth clamping wall 63 and sixth clamping wall 64 When the sixth sandwiching wall 64 is elastically deformed, the third pipe 19 is accommodated in the third receiving portion 20, and the fifth sandwiching wall 63 and the sixth sandwiching wall 64 are caused by the repulsive force of the sixth sandwiching wall 64 due to the elastic deformation. The third pipe 19 is pressed and clamped. By this pressing, the axial displacement of the third pipe 19 can be prevented. As a result, a plurality of clamps 1 are attached to a predetermined position of the third pipe 19 in the sub assembly line to form an assembly part of the clamp 1 and the third pipe 19, and then this assembly part is made of resin, metal on the main assembly line. The clamp 1 is displaced from a predetermined position because the holding force of the clamp 1 is weak when the assembled part is attached to the resin or metal panel 4 or the like in the process of transporting to the panel 4 or the like in the main assembly line. Thus, it is possible to eliminate the trouble of having to correct each time and the generation of unnecessary man-hours, and to provide a stable assembly.

  Further, for example, the fifth holding wall 63 and the sixth holding wall 64 press and hold the third pipe 19 by the repulsive force of the elastic deformation of the sixth holding wall 64, so that the third receiving portion 20 and the third pipe 19 are pressed. Can be eliminated. Therefore, for example, when the assembled parts of the clamp 1 and the third pipe 19 are attached to the panel 4 of the automobile, for example, due to the vibration of the automobile generated due to the backlash between the third pipe 19 and the third receiving portion 20. The chatter sound can be eliminated. Further, even if the third pipe 19 tries to move from the third receiving part 20 due to vibration, the movement can be prevented by the fifth elastic piece 53.

  In the clamp 1, for example, the fifth slit 65 is provided between the sixth sandwiching wall 64 and the fourth wall portion 38, so that the sixth sandwiching wall 64 can be elastically deformed with a simple structure. Further, it is not necessary to add extra parts such as a spring instead of elastically deforming the sixth clamping wall 64.

  Further, in the clamp 1, for example, the pair of the fifth clamping wall 63 and the sixth clamping wall 64 are provided on the inner side of the diameter of the third pipe 19 inserted into the third receiving portion 20. It is possible to reliably apply pressure to 19 and to prevent the clamp 1 from being displaced from a predetermined position because the holding force of the clamp 1 is weak.

  In the clamp 1, for example, the pair of third wall portion 37, fourth wall portion 38, third receiving portion 20, fifth elastic piece 53, pair of fifth sandwiching walls 63, and sixth sandwiching wall 64 are configured. By providing at least two or more, a plurality of third pipes 19 can be locked with one clamp 1 and one third pipe 19 is displaced from the clamp 1 and must be corrected each time. It is possible to eliminate the labor and waste of man-hours, and it is possible to provide a stable assembly of the clamp 1 and the third pipe 19 by attaching the plurality of clamps 1 to predetermined positions of the plurality of third pipes 19. .

Next, a clamp according to a second embodiment will be described. The second embodiment is almost the same as the first embodiment, and is different mainly in that the clamping wall presses the pipe. Hereinafter, a description will be given with reference to FIG. 14 to FIG. 18 with a focus on differences from the first embodiment. Note that the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment.
Here, FIG. 14 thru | or FIG. 18 is explanatory drawing explaining the form of the clamping wall of the clamp which concerns on 2nd Embodiment.

  As shown in FIG. 14, the clamp 1 according to the present embodiment includes a first opening end 21 and a first wall portion on the right side of the first receiving portion 16 that receives the attached first pipe 15 in the clamp body 2. The first connecting rib 22 provided between the first connecting ribs 22 has a first protrusion having an arcuate protrusion that has the same width as the depth direction of the first receiving portion 16 and presses the attached first pipe 15. The arc-shaped holding wall 71 extends, and a first slit 57 is provided between the first arc-shaped holding wall 71 and the first wall portion 35. Further, the upper surface of the second connecting rib 25 provided between the second opening end portion 23 on the left side of the first receiving portion 16 and the second wall portion 36 has the same width as the depth direction of the first receiving portion 16. A second arc-shaped holding wall 72 having an arc-shaped protrusion that presses the attached first pipe 15 is extended, and between the second arc-shaped holding wall 72 and the second wall 36. The 2nd slit 58 is provided in this. The first arcuate clamping wall 71 and the second arcuate clamping wall 72 form a pair, and the arcuate protrusions provided on the first arcuate clamping wall 71 and the second arcuate clamping wall 72 are: It is provided at a position where the portions of the attached first pipe 15 having a diameter of approximately 70 are pressed against each other, and when the first pipe 15 is not present, the first pipe 15 is set to be located inside the diameter 70 of the first pipe 15. Yes. Further, since the arc-shaped protrusions provided on the first arc-shaped holding wall 71 and the second arc-shaped holding wall 72 are arc-shaped, they absorb some deviation from the diameter 70 of the attached first pipe 15. can do.

As a result, when the first pipe 15 is attached to the first receiving portion 16, the first arcuate clamping wall 71 is elastically deformed to the first slit 57 side, and the second arcuate clamping wall 72 is elastically deformed to the second slit 58 side. The repulsive force serves as a holding force that prevents the axial displacement of the first pipe 15. Further, the arc-shaped protrusions provided on the first arc-shaped holding wall 71 and the second arc-shaped holding wall 72 are provided at positions where the portions of the attached first pipe 15 having a diameter of approximately 70 are pressed against each other. Therefore, there is no blur in the direction of the pressing force that presses the first pipe 15. Therefore, a large pressing force (holding force) can be obtained.
In addition, a first recess 73 is provided between the arc-shaped protrusion of the first arc-shaped holding wall 71 and the first opening end 21 with the bottom facing the first wall portion 35. Similarly, a second recess 74 is provided between the arc-shaped protrusion of the second arc-shaped holding wall 72 and the second opening end 23 with the bottom facing the second wall 36. . Therefore, the arc-shaped protrusions provided on the first arc-shaped holding wall 71 and the second arc-shaped holding wall 72 can press the first pipe 15 without being influenced by others.

  As shown in FIG. 15, the first arcuate clamping wall 71 and the second arcuate clamping wall 72 have the same width as the depth direction of the first receiving part 16, and the attached first pipe 15 is You may make it the shape of the 1st wedge-shaped clamping wall 75 and the 2nd wedge-shaped clamping wall 76 which have the wedge-shaped protrusion to press. This wedge-shaped protrusion enables a design that pinches the diameter 70 of the first pipe 15 at a pin point.

  Further, as shown in FIG. 16, the first arcuate clamping wall 71 and the second arcuate clamping wall 72 have the same width as the depth direction of the first receiving part 16 and the attached first pipe 15 is You may make it the shape of the 1st trapezoid clamping wall 77 and the 2nd trapezoid clamping wall 78 which have the trapezoid shaped protrusion to press. The trapezoidal protrusions are such that the first trapezoidal clamping wall 77 and the second trapezoidal clamping wall 78 have the diameter of the first pipe 15 even if the first pipe 15 is moved away from the first receiving part 16 by an external force or the like. Since it becomes parallel by 70, the diameter 70 part of the 1st piping 15 can always be clamped. Therefore, the maximum pressing force (holding force) at that time can always be obtained.

  Moreover, as shown in FIG. 17, the first arcuate clamping wall 71 and the second arcuate clamping wall 72 have the same width as the depth direction of the first receiving part 16 and the attached first pipe 15 is You may make it the shape of the 1st double mountain clamping wall 79 and the 2nd double mountain clamping wall 80 which have two protrusions to press. Since the two protrusions are arranged so as to straddle the diameter 70 portion of the first pipe 15, the diameter 70 portion of the first pipe 15 can be surely pressed, so that the maximum pressing force (holding force) is obtained. be able to.

  Further, as shown in FIG. 18, the shapes of the first arc-shaped holding wall 71 and the second arc-shaped holding wall 72 are the same width as the depth direction of the first receiving portion 16, and the attached first piping 15 You may make it the shape of the 1st spherical shape clamping wall 81 and the 2nd spherical shape clamping wall 82 which have the spherical-shaped protrusion which presses the 1st piping 15 from the upper part exceeding the diameter 70. FIG. By forming a spherical protrusion that presses the first pipe 15 from above the diameter 70 of the mounted first pipe 15, the first spherical holding wall 81, the first receiving part 16, and the second spherical shape are formed. Since the diameter of the 1st piping 15 can be pressed between each of the clamping wall 82 and the 1st receiving part 16, the maximum pressing force (holding force) can be obtained.

  As described above, in the clamp 1 according to the second embodiment, the holding wall of each form presses and holds the substantially diameter portion of the first pipe 15, so that the holding wall of each holding wall has. Since the first pipe 15 is pressed without dispersing the pressure, the maximum pressing force can be extracted. For example, the pair of first arcuate sandwiching walls 71 and second arcuate sandwiching walls 72 press and hold the substantially diameter portion of the first pipe 15 inserted into the first receiving portion 16, respectively. Since the first piping 15 is pressed against each other without dispersing the pressing force of the first arcuate clamping wall 71 and the second arcuate clamping wall 72, the maximum pressing force can be drawn and the holding force of the clamp 1 Therefore, the clamp 1 can be prevented from being displaced from a predetermined position.
