In Example 2 of this invention, a bush is sectional drawing which shows the structure attached to the wall panel. Similarly, it is a perspective view of a bush. Similarly, it is a side view of a bush. Similarly, it is a front view of a bush. It is the YY sectional view taken on the line of FIG.

Preferred embodiments of the present invention are shown below.
(1) The inner peripheral portion of the seal portion constitutes a stop portion that defines the amount of insertion of the cylindrical portion into the hole at a position where the second seal surface abuts on one surface of the wall panel Good to have. The inner peripheral portion of the seal portion is less likely to be deformed as compared to the outer peripheral portion. Therefore, when the inner peripheral portion constitutes the stop portion, the wiring member can be reliably held down when the cylindrical portion is properly inserted. In addition, since the second seal surface of the inner peripheral portion doubles as a seal function and also functions as a stop function, there is no need to provide a dedicated stop portion, and the configuration of the wiring member can be simplified.

  (2) The cylindrical portion may have an insertion guide portion whose diameter is reduced toward the front in the insertion direction. According to this, it is possible to easily and smoothly carry out the insertion work of the cylindrical portion into the hole by the guiding of the insertion guide portion.

  (3) It is preferable that a plurality of the insertion guide portions be provided at intervals in the circumferential direction on the outer peripheral side of the cylindrical portion. According to this, compared with the case where the insertion guide portion is provided over the entire circumference of the cylindrical portion, the sliding area between the insertion guide portion and the wall panel can be reduced, and the insertion workability can be improved. Further, the reliability of the invitation can be enhanced by providing the plurality of insertion guides at intervals in the circumferential direction without being unevenly distributed on one side in the circumferential direction.

  (4) The cylindrical portion may have a wire adhesion portion in which the diameter of the wire insertion hole is reduced at a part of the length in the insertion direction. According to this, it is possible to seal between the cylindrical portion and the wire through the wire contact portion. In addition, since the wire contact portion is not provided on the entire length of the cylindrical portion, it is possible to easily perform the operation of passing the wiring through the wiring insertion hole of the cylindrical portion.

  (5) The wall panel may be formed by superposing a base plate and a metal plate having higher rigidity than the base plate, and the wiring member may be configured to be in contact with the metal plate. The metal plate in contact with the wiring member has higher rigidity than the base plate and is less likely to be chipped. Therefore, the wiring member can be reliably attached to the wall panel through the metal plate.

  (6) The large diameter hole provided in the base plate is communicated with the small diameter hole provided in the metal plate to form the hole, and the metal plate has the large diameter at the opening edge portion of the small diameter hole. It has an inner side plate portion facing the hole and an outer side plate portion opposite to the inner side plate portion, and the second seal surface of the seal portion is in close contact with the outer side plate portion of the metal plate, The cylindrical portion may have a retaining surface which can be in contact with the inner side plate portion of the metal plate. When the cylindrical portion has the retaining surface, the wiring member can be prevented from being removed from the hole. Even when the large diameter hole and the small diameter hole are not in the concentric position when the base plate and the metal plate are overlapped, the retaining surface of the cylindrical portion is the inner plate surface portion of the metal plate in the large diameter hole. By being able to abut against the metal plate, the contact margin of the retaining surface against the metal plate can be reliably ensured, and the reliability of the retaining member can be enhanced.

The main body cylindrical portion 11B is formed thicker in the radial direction than each of the front side cylindrical portion 11A and the rear cylindrical portion 11C, and constitutes a main portion inserted into the hole 91 of the wall panel 90.

  The front side tubular portion 11A has a projecting ridge portion 14 that protrudes over the entire circumference at the front of the outer peripheral surface, and has an annular groove 15 between the projecting ridge portion 14 and the main body tubular portion 11B. A band-like tightening member 50 such as an insulation lock is fitted in the annular groove 15 of the front side cylindrical portion 11A.

  The front side tubular portion 11A has a wire contact portion 16 that protrudes over the entire circumference and reduces the diameter of the wire insertion hole 13 at the rear of the inner circumferential surface. When the bush 10 is in the natural state before attachment, the inner diameter of the wire insertion hole 13 is smaller than the outer diameter of the wire 80 (the outer diameter of the exterior material 83) in the wire contact portion 16. The diameter is larger than the outer diameter of the wiring 80 and substantially uniform. As shown in FIG. 1, the wire contact portion 16 is disposed at a position overlapping the fastening member 50 in the front-rear direction, directly receives the fastening force of the fastening member 50, and shrinks in the wire 80 passed through the wire insertion hole 13.

  As shown in FIG. 2, the main body cylindrical portion 11B has an end surface portion 17 which divides the annular groove 15 on the outer peripheral surface, and a plurality of insertion guide portions arranged at intervals in the circumferential direction behind the end surface portion 17 It has eighteen. Here, four insertion guide portions 18 are arranged at equal intervals in the circumferential direction, and each of the insertion guide portions 18 is formed in a rib shape extending in the front-rear direction with a trapezoidal cross section. Each insertion guide portion 18 has a guide surface 19 at its front surface, which tapers in diameter toward the rear.

  A common inclined surface 21 is provided over the entire circumference between the guide surface 19 and the end surface portion 17 of each insertion guide portion 18. The guide surface 19 and the common inclined surface 21 of each insertion guide portion 18 are continuous at a constant inclination angle. The guide surface 19 of each insertion guide portion 18 functions as a guide when inserting the cylindrical portion 11 into the hole 91 together with the common inclined surface 21.

  Further, as shown in FIG. 5, the main cylindrical portion 11 </ b> B has, on the rear surface of each of the insertion guides 18, a removal prevention surface 22 which is reduced in diameter sharply toward the rear. The retaining surface 22 of each insertion guide portion 18 is disposed to face the inner side plate surface portion 92 of the metal plate 90B in a state in which the cylindrical portion 11 is inserted into the hole 91, and the detachment of the cylindrical portion 11 from the hole 91 is It has a regulatory role.

  The rear cylindrical portion 11C has a cylindrical shape that is continuous in the front-rear direction with a substantially constant thickness, and is formed thinner than the front side cylindrical portion 11A as a whole. The rear cylindrical portion 11 </ b> C is configured to be able to flexibly deform following the wiring 80 extending rearward.

  As shown in FIG. 5, the seal portion 12 projects radially outward from the main body cylindrical portion 11B, and goes from the inner peripheral portion 23 located on the main body cylindrical portion 11B to the tip of the outer peripheral portion 24 located radially outward It gradually curves forward and gradually decreases in thickness from the inner circumferential portion 23 to the tip of the outer circumferential portion 24. The rear surface of the seal portion 12 is formed in an arc shape in cross section in which the whole is continuous without unevenness from the rear cylindrical portion 11C side to the tip of the outer peripheral portion 24.

  The outer peripheral portion 24 of the seal portion 12 protrudes from the inner peripheral portion 23 so as to bulge forward in a bowl shape (dome shape), and is disposed so as to cover the rear outer periphery of the main body cylindrical portion 11B in a natural state. The distal end of the outer peripheral portion 24 protrudes substantially in the frontward direction and, as shown in FIG. 4, is edged in a circular shape concentric with the cylindrical portion 11 in a front view.

  As shown in FIG. 5, the outer peripheral portion 24 of the seal portion 12 has a first seal surface 25 on the front surface. The first seal surface 25 is provided over the entire circumference on the tip end side of the outer peripheral portion 24. In a natural state, the first seal surface 25 constitutes a curved inner surface, and as shown in FIG. In this case, it is in close contact with the rear surface of the metal plate 90B, which is one surface of the wall panel 90, and is expanded in the radial direction.

  As shown in FIG. 5, the seal portion 12 has a step surface 26 between the front surface of the outer peripheral portion 24 and the front surface of the inner peripheral portion 23. The inner peripheral portion 23 of the seal portion 12 is sufficiently thick in the front-rear direction than the outer peripheral portion 24 through the step surface 26 and is less likely to be bent than the outer peripheral portion 24 in the front-rear direction.

  The inner circumferential portion 23 of the seal portion 12 has a second seal surface 27 on the front surface. The second seal surface 27 is provided along the radial direction substantially in the entire area of the front surface of the inner circumferential portion 23 and has a gap 28 between the insertion guide portion 18 and the retaining surface 22. It faces the retaining surface 22 of each insertion guide portion 18. The clearance 28 reduces the front-rear width toward the inner side (rear side) in the radial direction according to the inclination of the retaining surface 22, and the front-rear width on the inner side in the radial direction is the same as the thickness of the metal plate 90B or the metal plate 90B It is designed to be smaller than the thickness of the The outer peripheral side of the second seal surface 27 is on the outer side surface portion 93 of the metal plate 90B in a state where the cylindrical portion 11 is inserted into the hole 91 and the opening edge of the small diameter hole 91B of the metal plate 90B is fitted in the gap 28 It is configured to adhere closely.

Next, the method of attaching the bush 10 to the wall panel 90 and the attachment structure (see FIG. 1) will be described.
At the time of attachment, the wire 80 is inserted into the wire insertion hole 13 of the cylindrical portion 11. Since the tightening force from the tightening member 50 does not act on the cylindrical portion 11 when the wiring 80 is inserted, no large sliding resistance is generated between the wiring 80 and the cylindrical portion 11, and the insertion work is favorably performed. be able to. After the wire 80 is inserted, when the tightening member 50 is tightened in the diameter reducing direction, the tightening force acts on the wire contact portion 16, and the wire contact portion 16 strongly adheres to the outer peripheral surface of the exterior material 83 of the wire 80. The wire 80 is in close contact with the bush 10 substantially only through the wire contact portion 16, and the space between the wire 10 and the bush 10 is sealed in a watertight manner by the wire contact portion 16.

  Subsequently, the bush 10 is inserted into the hole 91 of the wall panel 90 from one side. In the process of inserting the bushes 10, the guide surface 19 of each insertion guide portion 18 slides on the opening edge of the small diameter hole 91B of the metal plate 90B, and each insertion guide portion 18 is elastically deformed in the diameter reducing direction. When the bush 10 is properly inserted into the hole 91, each insertion guide portion 18 elastically returns, and the whole is accommodated in the large diameter hole 91A. Then, as the insertion guide portions 18 elastically return, the retaining surfaces 22 of the insertion guide portions 18 are disposed so as to face and be in contact with the inner side plate surface portions 92 of the metal plate 90B. As a result, back slippage from the hole 91 of the bush 10 is restricted.

  In the process of inserting the bushes 10, the guide faces 19 of the respective insertion guide portions 18 slide along the edge of the small diameter hole 91B of the metal plate 90B, whereby the bush 10 is smoothly guided into the holes 91. Further, in the process of inserting the bush 10, the outer peripheral portion 24 of the seal portion 12 elastically deforms so as to expand in the radial direction while in contact with one surface of the metal plate 90B.

  When the bush 10 is properly inserted into the hole 91, the second seal surface 27 of the inner circumferential portion 23 abuts on the outer side plate portion 93 of the metal plate 90B, and the insertion operation of the bush 10 is stopped. At the same time, the second seal surface 27 of the inner circumferential portion 23 and the retaining surface 22 of each insertion guide portion 18 sandwich the metal plate 90B in the plate thickness direction (front-rear direction) so as to sandwich the outer plate surface portion 93 of the metal plate 90B. Close to Furthermore, when the bush 10 is properly inserted, the first seal surface 25 of the outer peripheral portion 24 closely adheres to a portion on the outer peripheral side of the outer side plate surface portion 93 in one surface of the metal plate 90B. In this manner, the inner and outer peripheral portions 23 and 24 of the seal portion 12 closely adhere to one surface of the metal plate 90B, whereby the space between the bush 10 and the wall panel 90 is sealed in a watertight manner.

  As described above, according to the first embodiment, the inner circumferential portion 23 and the outer circumferential portion 24 are provided in the seal portion 12 of the bush 10, and the seal portion 12 extends from the inner circumferential portion 23 to the outer circumferential portion 24. The second sealing surface 27 of the inner circumferential portion 23 is in close contact with one surface of the wall panel 90 when the cylindrical portion 11 of the bush 10 is inserted into the hole 91 so that the second sealing surface 27 adheres to one side. A state in which the first seal surface 25 of the outer peripheral portion 24 is in close contact can be secured, and good sealability can be secured.

  Here, when the second seal surface 27 of the inner peripheral portion 23 abuts on one surface of the wall panel 90 (the outer side plate surface portion 93 of the metal plate 90B), the insertion operation of the bush 10 is stopped. Therefore, the inner peripheral portion 23 of the seal portion 12 can have both the function of taking a seal with the wall panel 90 and the function of defining the amount of insertion of the cylindrical portion 11 into the hole 91. The configuration of the bush 10 can be simplified as compared with the case of being provided in the part of.

  Further, since the cylindrical portion 11 has the plurality of insertion guide portions 18, the insertion work of the cylindrical portion 11 into the hole 91 can be easily and smoothly performed by the introduction of each insertion guide portion 18. Moreover, since each insertion guide part 18 is arrange | positioned at fixed intervals in the circumferential direction of the cylinder part 11, the guide function of each insertion guide part 18 can be exhibited reliably.

  Further, since the cylindrical portion 11 is in close contact with the bush 10 substantially only through the wiring adhesion portion 16, when the wiring 80 is passed through the wiring insertion hole 13 of the cylindrical portion 11, the sliding between the wiring 80 and the cylindrical portion 11 The resistance does not become excessive, and the insertion work can be easily performed. In addition, the fastening member 50 is mounted on the outer peripheral surface of the cylindrical portion 11 at a position corresponding to the wire contact portion 16, and the fastening force of the fastening member 50 directly acts on the wire contact portion 16. The adhesiveness with 80 can be improved, and the sealing performance can be improved.

  Further, since the wall panel 90 is configured by superposing the base plate 90A and the metal plate 90B in the back and forth, and the bush 10 is configured to contact only the metal plate 90B, the metal plate 90B is more rigid than the base plate 90A. The bush 10 can be mounted with high reliability.

  Furthermore, an inner side plate surface 92 facing the large diameter hole 91A and an outer side plate 93 opposite thereto are provided at the opening edge of the small diameter hole 91B of the metal plate 90B, and the second seal surface 27 of the seal 12 is metal. The large diameter hole 91A and the small diameter hole 91B are concentric because the close contact with the outer side plate portion 93 of the plate 90B and the retaining surface 22 of the cylindrical portion 11 is arranged to be able to abut the inner side plate portion 92 of the metal plate 90B. Even when there is no position, the contact margin of the retaining surface 22 against the inner side plate surface 92 of the metal plate 90B can be reliably ensured, and the reliability of the retaining can be improved. In addition, since the retaining surface 22 is formed on the rear surface of the insertion guide portion 18 and the insertion guide portion 18 combines the guiding function and the retaining function, the configuration can be simplified.

And a seal portion 12E. As shown in FIG. 6, the wall panel 90 </ b> E is configured by stacking the base plate 90 </ b> A and the metal plate 90 </ b> B in the front-rear direction as in the first embodiment. In the case of the second embodiment, the base plate 90A and the metal plate 90B have holes 91E having the same diameter and communicating concentrically.

  As shown in FIG. 10, the cylindrical portion 11E has a cylindrical inner cylindrical portion 31 elongated in the front-rear direction, and an outer cylindrical portion 32 surrounding the outer peripheral side of the inner cylindrical portion 31. A front view annular cutout space 33 is formed between the inner cylindrical portion 31 and the outer cylindrical portion 32. The inner cylindrical portion 31 and the outer cylindrical portion 32 face each other in parallel via the cutout space 33, and are connected to each other by a connecting portion 34 provided midway in the front-rear direction. The notch space 33 is divided and disposed on both the front and rear sides of the connecting portion 34. The front portion of the inner cylindrical portion 31 projects forward from the outer cylindrical portion 32, and the rear portion of the inner cylindrical portion 31 protrudes rearward from the outer cylindrical portion 32.

  The inner cylindrical portion 31 has a wiring insertion hole 13E inside. The inner diameter of the wiring insertion hole 13E is configured to have a constant diameter in the front-rear direction.

  As shown in FIGS. 7 and 8, the outer cylinder portion 32 has a plurality of slits 35 extending in such a manner as to cut backward, and between the slits 35, a plurality of thick insertion guide portions 18E are arranged in the circumferential direction. Have. Each insertion guide portion 18E has a guide surface 19E inclined rearward and a close contact surface 36 gently inclined rearward in the diameter reducing direction on the front surface, and the close contact surface 36 and the guide surface 19E. And a top 37 between them. The top 37 is the most radially thickened portion of the insertion guide 18E.

  As shown in FIG. 10, the seal portion 12E protrudes radially outward from the reduced-diameter portion on the rear end side of the outer cylindrical portion 32, and similarly to the first embodiment, gradually from the inner peripheral portion 23E to the outer peripheral portion 24E The first seal surface 25E is provided on the front surface of the outer peripheral portion 24E, the second seal surface 27E is provided on the front surface of the inner peripheral portion 23E, and the first seal surface 25E and the second seal surface are formed. A step surface 26E is provided between it and 27E.

  When the wire 80 is inserted into the wire insertion hole 13E of the cylindrical portion 11E during assembly, the exterior material 83 of the wire 80 is in close contact with the entire inner peripheral surface of the wire insertion hole 13E (see FIG. 6). The clamping member 50 fitted to the front of the inner cylindrical portion 31 is clamped. Thereby, the space between the wiring 80 and the bush 10E is sealed in a watertight manner.

  Subsequently, the cylindrical portion 11E is inserted into the hole 91E of the wall panel 90E from one side. The cylindrical portion 11E is inserted into the inner peripheral surface of the hole 91E of the wall panel 90E by the guiding of the guide surface 19E of each insertion guide portion 18E. In the process of inserting the cylindrical portion 11E, each insertion guide portion 18E slides on the inner peripheral surface of the hole 91E of the wall panel 90E. When the cylindrical portion 11E is properly inserted into the hole 91E of the wall panel 90E, the second seal surface 27E of the inner peripheral portion 23E abuts on one surface of the metal plate 90B of the wall panel 90E, and the insertion operation of the cylindrical portion 11E is stopped.
