Description

  The present invention relates to a covering member that covers the vicinity of a fuel filler opening provided in a vehicle and prevents mud, water, and the like from entering.

  A fuel filler port for supplying fuel to the vehicle is composed of a tip portion of a fuel filler pipe extending from the fuel tank. The fuel supply pipe generally extends from the fuel tank toward the tire house of the vehicle. And the front-end | tip part of an oil supply pipe | tube protrudes in the clearance gap between a wheel house outer and a side member outer through the hole provided in the wheel house outer. On the other hand, the side member outer is provided with an opening at a position facing the hole. Therefore, the oil filler opening, which is the tip of the oil filler pipe, is arranged inside the opening.

  A gap between the wheel house outer and the side member outer communicates with the inside of the tire house, that is, the lower outside of the vehicle via the hole. For this reason, mud, water, or the like that jumps up during traveling may enter the gap between the wheel house outer and the side member outer through this hole, and the vicinity of the fuel filler opening may be exposed to mud, water, or the like. Therefore, in order to prevent the intrusion of mud, water, etc., it has been conventionally practiced to block the tip end portion of the oil supply pipe from the lower outside of the vehicle by a cylindrical covering member.

  The covering member is generally made of an elastic material such as rubber, and connects the opening covering portion that covers the inner edge of the opening, the oil supply pipe side covering portion that covers the outer edge of the oil supply pipe, and the opening covering portion and the oil supply pipe side covering portion. And is formed in a cylindrical shape. Among these, the opening covering portion covers the inner edge of the opening portion, the oil supply tube side covering portion covers the outer edge of the oil supply tube, and the oil supply pipe positioned between the opening covering portion and the oil supply tube side covering portion is provided inside the connecting portion. By accommodating, the front-end | tip part of a fuel filler opening is interrupted | blocked from the downward direction of a vehicle. Therefore, mud, water or the like entering from the lower side of the vehicle through the hole is prevented from reaching the vicinity of the tip of the oil supply pipe.

  Here, the opening provided in the side member outer is covered with a lid for partitioning the opening from the outside of the vehicle. Since this lid is openable and closable so as to supply fuel to the fuel filler opening, for example, when refueling in rainy weather, water may enter the cylinder of the covering member through the opening. The water that has entered the inside of the cylinder moves downward in the vertical direction. Generally, however, the covering member is assembled to the opening and the oil supply pipe so that a part of the oil supply pipe side covering part is disposed below the vertical direction. Therefore, the water that has entered the inside of the cylinder accumulates on the lower side in the vertical direction around the oil supply pipe side covering portion.

  Therefore, conventionally, water that has entered the inside of the cylinder of the covering member is discharged to the outside by providing a drain hole in a portion of the oil supply pipe side covering portion that is disposed below the vertical direction. In order to prevent water, mud, or the like that has sprung from the bottom of the vehicle from entering the inside of the cylinder of the covering member through this drain hole, or to prevent foreign matter such as mud from clogging in the drain hole, Further, a fin-like protector was provided below the surface to prevent water or mud from reaching the drain hole (for example, Patent Document 1).

  FIG. 8 shows a cross-sectional view schematically showing the covering member disclosed in Patent Document 1. In FIG. FIG. 8 shows a state in which the opening covering portion 101 of the covering member 100 disclosed in Patent Document 1 is assembled to the opening 103 of the side member outer 102 and the oil supply pipe side covering portion 105 is assembled to the oil supply pipe 106. .

  According to the covering member 100 disclosed in Patent Document 1, an oil supply port 107 which is a tip portion of the oil supply pipe 106 is housed inside the cylinder of the covering member 100 and is blocked from the lower outside 108 of the vehicle. Moreover, since the drain hole 110 is provided in the part arrange | positioned below the vertical direction among the oil supply pipe side coating | coated parts 105, the water which entered the cylinder inside of the coating | coated member 100 is outside from this drain hole 110. Discharged. Since the fin-shaped protector 111 is provided below the drain hole 110, water, mud, and the like splashed from the lower outside 108 of the vehicle are blocked by the protector 111 and do not easily reach the drain hole 110. Thus, water, mud, and the like are prevented from entering the inside of the cylinder of the covering member 100 through the drain hole 110.

  Here, since the drain hole is formed in the lower part of the covering member in the vertical direction, the position of the drain hole is determined in one place depending on the arrangement direction of the opening and the oil supply pipe and the shape of the oil supply pipe.

  On the other hand, since the oil supply pipe is generally formed in a shape curved toward the rear of the vehicle, the covering member also needs to be formed in a curved shape along the oil supply pipe, and the end face of the opening covering portion and the oil supply port side covering portion Are set so as to intersect each other at a predetermined angle. And the molding die used when molding the covering member needs to set the dividing line between one die and the other die perpendicular to both the end face of the opening covering portion and the end face of the filler opening side covering portion. Therefore, the direction of the dividing line is determined to be a fixed direction.

Therefore, depending on the shape of the opening, the oil supply pipe, etc., the drain hole is formed at a position shifted from the dividing line, and the protector covering the drain hole is also formed at a position shifted from the dividing line. In this case, the protector cannot be extracted from the mold or is very difficult to extract. The protector can be provided so that it can be punched by extending the protector from the position near the drain hole to the dividing line. However, in this case, the protector part becomes larger than necessary. There is a problem that the number of required materials increases remarkably and the cost of the material required for the covering member increases.
Japanese Patent Laid-Open No. 9-188147

  The present invention has been made in consideration of the above circumstances, and is a covering member having a drain hole in the oil supply pipe side covering portion, such as water or mud from the drain hole to the inside of the cylinder without providing a protector or the like. The purpose is to provide something that prevents entry.

The covering member of the present invention that solves the above problems includes an opening covering portion that covers the inner edge of the opening portion provided in the vehicle, a tube side covering portion that covers the outer edge of the oil supply pipe disposed inside the opening portion, and A connecting portion that connects the opening covering portion and the tube side covering portion; and a substantially cylindrical covering member,
The tube side covering portion has a base portion continuous to the connecting portion and a seal portion protruding from the base portion into the cylinder and elastically contacting the oil supply pipe, and provided with a drain hole communicating with the inside and outside of the cylinder in a lower portion in the vertical direction of the base portion. ,
After the pipe side covering part is assembled to the oil supply pipe, the seal part is displaced in the direction of the inner peripheral surface of the connecting part, so that the drain hole is disposed at a position facing the surface of the oil supply pipe. It is characterized by that.

  Moreover, it is preferable that the said drain hole is provided in the base end part extended in radial direction inside among the said base parts, and being connected with the said seal part.

  It is preferable that the base portion has a reduced diameter portion that is reduced in the radial direction, and a portion of the reduced diameter portion that faces the drain hole is a substantially flat surface.

  In the covering member of the present invention, the tube-side covering portion that covers the oil supply pipe of the covering member is composed of a base portion and a seal portion, and a drain hole is provided in the base portion. This drain hole is in a state of being arranged at the lower part in the vertical direction after the pipe side covering portion is assembled to the oil supply pipe. Accordingly, the water that has entered the cylinder of the covering member and has moved downward in the vertical direction is discharged to the outside of the covering member through the drain hole. And at this time, the oil supply pipe is inserted into the pipe side covering part, so that the seal part is pressed by the oil supply pipe and is displaced toward the inner peripheral surface of the connecting part, and the drainage hole is the surface of the oil supply pipe. Therefore, the oil supply pipe prevents water and mud from entering the drain hole. Therefore, the covering member of the present invention prevents water or mud from entering the drain hole without providing a separate protector or the like. For this reason, the manufacturing cost of the covering member is reduced by reducing the material required for the covering member and reducing the molding failure and the mold release failure.

  In the covering member of the present invention, the base end portion extending inward in the radial direction and connected to the seal portion in the base portion is a portion close to the oil supply pipe in the base portion. Therefore, when a drain hole is provided in the base end portion, the entry of water or mud into the drain hole is more reliably prevented.

  When the base portion is provided with a reduced diameter portion that is reduced in the radial direction, the base portion has a bellows shape and the degree of freedom of deformation is increased, so that the seal portion is surely elastically contacted by the tube side covering portion. At this time, by making the portion of the reduced diameter portion facing the drain hole a substantially flat surface, the water inside the cylinder can easily reach the drain hole, and the water that has entered the cylinder can be discharged more reliably. become.

  The covering member according to the present invention has a substantially cylindrical shape, and has an opening covering portion, a tube side covering portion, and a connecting portion that connects the opening covering portion and the tube side covering portion. Although the material which comprises the coating | coated member of this invention is not ask | required in particular, it is desirable to form at least a pipe side coating | coated part with comparatively soft elastic materials, such as resin and rubber | gum. This is for displacing the seal part and the base part when the pipe side covering part is assembled to the oil supply pipe, and for elastically contacting the seal part to the oil supply pipe.

  The opening covering portion has a shape corresponding to the inner edge shape of the opening portion of the vehicle, and can be formed in various shapes according to the shape of the opening portion. The opening covering portion only needs to cover the inner edge of the opening. For example, the opening covering portion may be formed to have a substantially U-shaped cross section, and the inner edge of the opening may be sandwiched inside a portion bent into a U shape. it can. Further, the opening covering portion may be provided with a seal lip or the like for sealing the gap between the peripheral edge portion of the opening portion and the opening covering portion in order to reliably cover the opening portion.

  The tube side covering portion has a base portion continuous to the connecting portion and a seal portion protruding from the base portion into the cylinder, and among these, the seal portion elastically contacts the oil supply tube and covers the outer edge of the oil supply tube. Accordingly, at least the seal portion of the tube side covering portion is formed in a shape corresponding to the outer edge shape of the oil supply tube. The seal portion may be in any shape that can seal the outer edge of the oil supply pipe, and the shape is not particularly limited. Further, a seal lip that seals a gap between the seal portion and the outer edge of the oil supply pipe may be provided on the seal portion.

  When the pipe side covering portion is assembled to the oil supply pipe, the seal portion is pressed toward the opening covering portion by the oil supply pipe. For this reason, after being assembled to the oil supply pipe, the seal portion is displaced toward the inner peripheral surface of the connecting portion. Accordingly, the base portion continuous with the seal portion is also displaced in the direction of the inner peripheral surface of the connecting portion with this displacement. Due to the displacement of the base, the drain hole provided in the base is displaced to a position facing the surface of the oil supply pipe. In addition, it cannot be overemphasized that a pipe side coating | coated part is assembled | attached to an oil supply pipe | tube so that this drain hole may be arrange | positioned in the lower part of the perpendicular direction.

  By arranging the drain hole in the lower part in the vertical direction, the water that has entered the inside of the cylinder of the covering member and moved to the lower part in the vertical direction is discharged to the outside through the drain hole. And since a drain hole is arrange | positioned in the position which faces the surface of an oil supply pipe | tube, the mud, water, etc. which bounced at the time of driving | running | working etc. are interrupted | blocked by an oil supply pipe | tube, and it becomes difficult to reach a water drain hole. For this reason, it is prevented that mud, water or the like enters the inside of the cylinder through the drain hole, or mud is clogged in the drain hole.

  The connecting portion only needs to have a cylindrical shape that connects the opening covering portion and the tube side covering portion. Depending on the arrangement of the opening portion and the oil supply pipe, various types such as a straight tube shape, a bent shape, and a curved shape are available. It can be formed into a shape. Moreover, at least one of the peak part diameter-reduced in a radial direction and the trough part diameter-expanded in a radial direction can be provided in a connection part, and a connection part can also be formed in a bellows shape. In this case, since the connecting portion can be deformed, it can be assembled while changing the shape of the connecting portion according to the variation in the arrangement position of the opening and the oil supply pipe, and the arrangement position of the opening and the oil supply pipe Can be absorbed.

  Only one or both of the peaks and valleys may be provided. Moreover, the number of peaks and valleys may be only one, or two or more. As the number of peaks and valleys increases, it becomes easier to absorb variations in the positions of the openings and the oil supply pipes. And when providing a peak part and a trough part alternately continuously, since a connection part becomes deformable more variously, so that the variation in the arrangement position of an opening part and an oil supply pipe may be absorbed more reliably. Become.

  Furthermore, it is preferable to provide rigidity by configuring at least a portion in the vicinity of the base portion of the connecting portion with a highly rigid material or fixing it to another member. For example, when the base is deformed by applying some external force after the pipe-side covering is assembled to the oil supply pipe, the oil supply pipe moves due to the deformation of the base, and the arrangement position of the oil supply port that is the tip of the oil supply pipe is May move. However, by providing rigidity to at least the portion in the vicinity of the base portion of the connecting portion, the base portion is fixed by the connecting portion and is difficult to deform, so the oil supply pipe also becomes difficult to move, and the position of the oil supply port is elastic. Can be fixed to.

  Moreover, when a connection part can deform | transform, it is preferable to fix at least the part of the base part vicinity to another member among connection parts. When the connecting part is provided with a crest or a trough so that the connecting part can be deformed, the connecting part is deformed when the pipe side covering part is assembled to the oil supply pipe, and the pressing force by the oil supply pipe is absorbed by the connecting part. There is a case. In this case, the pressing force by the oil supply pipe does not sufficiently act on the seal portion and the base portion, and it becomes difficult to displace the seal portion and the base portion, so that the assembling work may be difficult. However, by fixing at least the portion in the vicinity of the base portion of the connecting portion to the other member, it is possible to prevent deformation of the connecting portion when assembling the pipe side covering portion to the oil supply pipe, and to reliably displace the seal portion and the base portion. Since it can do, there exists an advantage by which the assembly | attachment operation | work with respect to the oil supply pipe | tube of a pipe side coating | coated part is performed more easily.

  The base portion is preferably formed in a bellows shape having a reduced diameter portion that is at least radially reduced. In this case, there is an advantage that the seal portion of the tube side covering portion is easily displaced in the direction of the inner peripheral surface of the connecting portion because the base portion is freely deformable.

  In addition, when the base is formed in a shape having a reduced diameter portion and a drain hole is provided at the base end, at least a portion of the reduced diameter portion facing the drain hole has a substantially flat surface. preferable. In other words, the diameter-reduced portion has a diameter reduced in the radial direction except for a portion facing the portion provided with the drain hole, and protrudes into the cylinder, and a protruding height is low in the portion facing the drain hole. It is preferable that it is or does not protrude.

  When the drain hole is provided at the base end, depending on the positional relationship between the drain hole and the reduced diameter part, the reduced diameter part may impede the water reaching the drain hole. By making the part which opposes the drain hole out of the diameter part into a substantially flat surface, the arrival to the drain hole of water is not inhibited by the reduced diameter part. In addition, you may provide this substantially flat surface smaller than the part which opposes a drain hole. In this case, the effect is smaller than the case where the substantially flat surface is provided on the entire portion facing the drain hole, but the water is more likely to reach the drain hole by the amount of the substantially flat surface.

  When a plurality of reduced diameter portions are provided, at least a portion facing the drain hole of the reduced diameter portion adjacent to the drain hole may be a substantially flat surface. Furthermore, when forming a connection part in a bellows shape, the peak part of a connection part can also be made into a substantially flat surface similarly. In this case, the water that has entered the cylinder is more likely to reach the drain hole.

Hereinafter, the covering member of the present invention will be described with reference to the drawings.

(Example 1)
A diagram schematically showing a cross section of the covering member of Example 1 is shown in FIG.

  The covering member 1 of the first embodiment is made of rubber, has an opening covering portion 2, a tube side covering portion 3, and a connecting portion 5, and has a cylindrical shape in which the tube side covering portion 3 has a smaller diameter than the opening covering portion 2. It is formed in the shape of. Moreover, in the coating | coated member 1 of the present Example 1, the connection part 5 is formed in the bellows shape which has the one trough part 6 which protrudes outside a cylinder.

  Of these, the opening covering portion 2 is a portion that covers the inner edge 10 of the opening portion 8 provided in the side member outer 7 of the vehicle, and a first ring having a substantially U-shaped cross section protruding outward from the cylinder at the end portion thereof. A holding unit 11 is provided. A portion adjacent to the first ring holding portion 11 is provided with a first sandwiching portion 12 having a substantially U-shaped cross section that protrudes toward the inside of the cylinder. In the opening covering portion 2 in the covering member 1 of the first embodiment, the U-shaped interior of the first holding portion 12 is a portion that covers the inner edge 10 of the opening 8. When the opening covering portion 2 is assembled to the opening portion 8, the inner edge 10 of the opening portion 8 is covered with the first holding portion 12 by opening the first holding portion 12 while being pulled and deformed. The peripheral portion of the portion 8 is sandwiched inside the U-shape of the first sandwiching portion 12.

  A metal first ring member 13 is held inside the U-shape of the first ring holding portion 11. This ring member has a larger diameter than the inner edge 10 of the opening 8. For this reason, in the covering member 1 of the first embodiment, the opening covering portion 2 is sandwiched between the peripheral edge portion of the opening portion 8 and the first ring member 13. For example, the covering member 1 is pulled in the direction of the tube side covering portion 3. Even in such a case, the opening covering portion 2 is prevented from entering the opening portion 8.

  Furthermore, a seal lip 15 extending in the direction of the first clamping portion 12 is provided over the entire circumference of the opening covering portion 2 on the protruding end side of the first ring holding portion 11 in the opening covering portion 2. The seal lip 15 is a relatively thin portion and easily deforms. Therefore, when the sealing lip 15 is pressed against the peripheral edge of the opening 8 when the opening covering portion 2 is assembled to the opening 8, the sealing lip 15 is deformed along the surface shape of the peripheral edge of the opening 8. The gap between the peripheral edge portion of the opening 8 and the opening covering portion 2 is sealed.

  The tube side covering portion 3 includes a base portion 16 and a seal portion 17. The base portion 16 is a portion that continues to the connecting portion 5 and is formed in a bellows shape having one reduced diameter portion 18 that is partially reduced in diameter in the radial direction. Of the reduced diameter portion 18, the end side opposite to the connecting portion 5 is a folded portion 20 whose diameter is increased again. Further, a portion of the base portion 16 closer to the seal portion 17 than the folded portion 20 is a base end portion 21 extending in a standing wall shape toward the inside in the radial direction. A part of the base end 21 is provided with a drain hole 22 that communicates between the inside and outside of the cylinder.

  The seal portion 17, which is located at the distal end of the base end portion 21 and protrudes toward the inside of the tube of the tube side covering portion 3, is thicker than the base portion 16, and the surface on the opening covering portion 2 side is raised. It has a shape. The inner diameter of the seal portion 17 is smaller than the outer diameter of an oil supply pipe described later.

  Further, as shown in the schematic perspective view of FIG. 2, the reduced diameter portion 18 has a substantially flat surface at a portion 23 facing the drain hole 22.

  At the end of the connecting portion 5 on the tube-side covering portion 3 side, as shown in the enlarged view of the main part in FIG. 3, a second ring holding portion 25 protruding outside the cylinder so as to have a substantially U-shaped cross section. Is formed. Furthermore, a portion of the connecting portion 5 adjacent to the second ring holding portion 25 is provided with a second holding portion 28 that protrudes into the cylinder so as to have a substantially U-shaped cross section. This 2nd clamping part 28 clamps the peripheral part of the substantially circular hole 27 provided in the wheel house outer 26 of a vehicle inside a U-shape. The second ring member 30 having a diameter larger than that of the hole 27 is held in the U-shape of the second ring holding portion 25 in the same manner as the first ring holding portion 11.

  In the covering member 1 according to the first embodiment, the connecting portion 5 sandwiches the peripheral portion of the hole portion 27 provided in the wheel house outer 26 with the second sandwiching portion 28, and the peripheral portion of the hole portion 27 and the second peripheral portion. It is held by the vehicle by being pinched by the ring member 30. Similarly to the opening covering portion 2, the second ring holding portion 25 holds the second ring member 30 having a diameter larger than that of the hole portion 27, so that the oil supply pipe 31 is connected to the tube side covering portion 3. When inserting, it fixes so that the part by the side of the pipe | tube side coating | coated part 3 among the pipe | tube side coating | coated part 3 and the connection part 5 may not enter this hole part 27 inside.

  FIG. 4 is a schematic cross-sectional view illustrating a state in which the pipe side covering portion 3 of the covering member 1 of the first embodiment is assembled to the oil supply pipe 31.

  The inner diameter of the seal part 17 in the pipe side covering part 3 is smaller than the outer diameter of the oil supply pipe 31. Therefore, when the oil supply pipe 31 is inserted into the covering member 1 from the pipe side covering part 3 side after the opening covering part 2 is assembled to the opening 8 of the vehicle, the seal part 17 has a shape along the outer edge of the oil supplying pipe 31. It extends into the inner side of the cylinder while extending in the direction of displacement, and is displaced toward the inner peripheral surface 34 of the connecting portion 5. Further, with the displacement of the seal portion 17, the base portion 16 continuing to the seal portion 17 is also displaced in the direction of the inner peripheral surface 34 of the connecting portion 5. For this reason, the drain hole 22 provided in the base portion 16 is displaced to a position facing the surface 32 of the oil supply pipe 31. Therefore, after the pipe side covering portion 3 is assembled to the oil supply pipe 31, the water drain hole 22 provided in the base portion 16 is disposed in the lower portion of the covering member 1 in the vertical direction and is provided on the surface 32 of the oil supply pipe 31. It is arranged at the facing position.

  Since the drain hole 22 is arranged in the lower part of the covering member 1 in the vertical direction, the water that has entered the inside of the cylinder of the covering member 1 passes through the drain hole 22 as shown by the broken arrow in FIG. To be discharged. Since the drain hole 22 is disposed at a position facing the surface 32 of the oil supply pipe 31, the water drain hole 22 is shielded by the oil supply pipe 31, and mud, water, etc. bounced off during traveling, etc. It is prevented that the water drain hole 22 enters or the water drain hole 22 is clogged with mud or the like.

  For this reason, according to the covering member 1 of the present embodiment, since it is not necessary to provide a separate protector or the like even though the drain hole 22 can be provided to discharge the water that has entered the inside of the cylinder, the material required for the protector is eliminated. Is reduced to reduce material costs. And since a protector is not required, the shaping | molding defect and the failure defect at the time of mold release are reduced, and the manufacturing cost of the coating | coated member 1 is reduced.

  In the covering member 1 of the first embodiment, the connecting portion 5 is sandwiched between the second ring member 30 and the peripheral portion of the hole portion 27 and is fixed to the wheel house outer 26 of the vehicle. In doing so, only the tube side covering portion 3 of the covering member 1 is displaced. Therefore, the assembling work of the pipe side covering portion 3 to the oil supply pipe 31 is very easily performed.

  Furthermore, as shown in FIG. 2, the entire portion 23 of the reduced diameter portion 18 that faces the drain hole 22 has a substantially flat surface. For this reason, the movement of the water inside the cylinder is not hindered by the reduced diameter portion 18, and the water that has entered the cylinder is discharged more reliably.

  For example, as shown in FIG. 5, the drain hole 22 may be provided up to a position along the cylindrical surface connected to the base end portion 21 in the base portion 16. In this case, since the drain hole 22 is disposed at the lowermost part, the water that has entered the inside of the cylinder is more reliably discharged to the outside.

(Example 2)
The covering member of Example 2 has the same tube side covering portion as that of Example 1, the hole opening covering portion and the connecting portion are formed of a relatively hard material, and the tube side covering portion is formed of a comparatively soft material. In addition, the connecting portion is not fixed to the vehicle. FIG. 6 schematically shows a cross section of the covering member of the second embodiment.

  In the covering member 35 of the second embodiment, the opening covering portion 36 is made of PP (polypropylene) which is a relatively hard material, and the opening covering portion 37 is assembled to the side member outer 39 by tapping.

  In the covering member 35 of the second embodiment, when the opening covering portion 36 is assembled to the opening portion 38, the sealing material 41 is pasted on the flange portion 40 of the opening covering portion 36 corresponding to the peripheral portion of the opening portion 38 in advance. In addition, after the covering member 35 is inserted into the opening 38, an attachment hole (not shown) provided in the flange 39 is fastened and fixed to the side member outer 39 by tapping. Therefore, the opening covering portion 36 is firmly fixed to the opening portion 38 even when the opening covering portion 36 is not sandwiched between the peripheral edge portion of the opening portion 38 and the ring member as in the covering member of the first embodiment.

  The connecting portion 42 is made of PP, which is the same material as the opening covering portion 36, and is formed in a cylindrical shape having no peaks or valleys. Further, the connecting portion 42 is not provided with the second ring holding portion and the second holding portion as provided in the connecting portion of the first embodiment. For this reason, in the covering member 35 of the second embodiment, the connecting portion 42 is not fixed to the vehicle, and the covering member 35 is held by the vehicle only by the opening covering portion 36 and the tube side covering portion 43.

  The tube side covering portion 43 is made of TPO (olefinic thermoplastic elastomer) which is a relatively soft material, and includes a seal portion 45 and a base portion 46 having the same shape as the tube side covering portion of the covering member of the first embodiment.

  When the pipe side covering portion 43 of the covering member 35 of the second embodiment is assembled to the oil supply pipe, the sealing portion 45 is connected to the inner peripheral surface 47 of the connecting portion 42 in the same manner as the sealing portion 45 of the first embodiment shown in FIG. The base portion 46 that is displaced in the direction and continues to the seal portion 45 is also displaced in the direction of the inner peripheral surface 47 of the connecting portion 42 as the seal portion 45 is displaced. For this reason, the drain hole 48 provided in the base part 46 is arrange | positioned in the position facing the surface of a fuel supply pipe | tube while being arrange | positioned in the lower part of the perpendicular direction among the coating | coated members 35. Therefore, the drain hole 48 is shielded by the oil supply pipe, and mud, water, etc. enter the drain hole 48, and the drain hole 48 is prevented from being clogged with mud.

  For this reason, according to the covering member 35 of the second embodiment, it is not necessary to separately provide a protector or the like, similarly to the covering member of the first embodiment, thereby reducing the material cost and the manufacturing cost.

  In the covering member 35 of the second embodiment, the opening covering portion 36 and the connecting portion 42 are made of a relatively hard material, and the tube side covering portion 43 is made of a relatively soft material. Therefore, when the oil supply pipe is inserted into the pipe side covering portion 43 of the covering member 35 of the second embodiment, only the pipe side covering portion 43 made of a relatively soft material is displaced, so that the relatively hard material is used. The shapes of the connecting portion 42 and the opening covering portion 36 are maintained. For this reason, it is very easy to assemble the pipe side covering portion 43 to the oil supply pipe without particularly fixing the connecting portion 42 to the vehicle.

  Further, for example, as shown in FIG. 7, the base 46 of the covering member 35 may not be provided with the reduced diameter portion 50. In this case, since the shape of the base 46 is simplified and a mold for manufacturing the covering member 35 can be manufactured at a low cost, the manufacturing cost of the covering member 35 is further reduced.
