Description

  The present invention relates to a covering member that is attached to a counterpart member having two panels each having an opening and covers a gap between the two panels.

  As a kind of covering member, a covering member (so-called inlet shield) that covers a portion near a fuel supply opening of a vehicle panel is known. As shown in FIG. 9, this type of covering member 101 generally includes a peripheral portion of an opening (hereinafter referred to as a first opening 195) provided in a side member outer 191 of the vehicle, and a wheel house outer 192 of the vehicle. And a peripheral portion of an opening (hereinafter referred to as a second opening 198) provided in each of the openings, and covers a gap between the side member outer 192 and the wheel house outer 198. In the covering member 101 shown in FIG. 9, a portion attached to the peripheral portion of the first opening 195 (hereinafter referred to as the first attaching portion 120) engages with the peripheral portion of the first opening 195 and is substantially C The diameter is expanded by a first ring member 181 having a letter shape. For this reason, the 1st attaching part 120 is attached to the peripheral part of the 1st opening 195 with high sealing performance. A portion attached to the peripheral portion of the second opening 198 (hereinafter referred to as a second attaching portion 130) engages with the peripheral portion of the second opening 198 and has a substantially C-shaped second ring member 182. The diameter is expanded by. For this reason, the second attachment portion 130 is also attached to the periphery of the second opening 198 with high sealing performance.

  By the way, when this type of covering member 101 is attached to the side member outer 192 and the wheel house outer 198, first, the first attachment portion 120 is engaged with the peripheral portion of the first opening 195 and the second attachment portion 130. Is engaged with the peripheral edge of the second opening 198. Next, the first ring member 181 is attached to the first ring groove 125 provided in the first attachment portion 120, and the second ring member 182 is provided in the second ring groove 135 provided in the second attachment portion 130. Installing. The first ring member 181 is required to function as a retaining member for preventing the first attachment portion 120 from being detached from the peripheral edge of the first opening 195. In order to mount the first ring member 181 in the first ring groove 125, it is necessary to insert the first ring member 181 into the first ring groove 125 while elastically deforming the first ring member 181 in the reduced diameter direction. Further, since the second ring member 182 needs to be elastically deformed in a small space, the operation of inserting the second ring member 182 into the second ring groove 135 is further complicated. For this reason, the operation | work which attaches this kind of coating | coated member 101 to the side member outer 192 and the wheel house outer 198 was very complicated. Furthermore, when the second ring member 182 is attached to the second attachment portion 130, it is necessary to push the second ring member 182 further into the first opening 195 and the second opening 198. Since the second ring member 182 has a larger diameter than at least the second opening 198, this operation is very complicated.

  For this reason, the inventor of the present invention devised a covering member 101 using a hard regulating member instead of the first ring member 181 and the second ring member 182 (see Patent Document 1). The regulating member in the covering member 101 has a claw portion and a flange portion, and the claw portion and the flange portion sandwich the peripheral portion of the first opening 195 or the peripheral portion of the second opening 198. For this reason, the covering member 101 disclosed in Patent Document 2 can be easily attached to the mating member 109.

  By the way, the covering member 101 disclosed in Patent Document 2 can be easily attached to the side member outer 192 and the wheel house outer 198, but the regulating member has to be resin-molded. For this reason, the covering member 101 disclosed in Patent Document 2 has a problem that it is difficult to manufacture at low cost. Therefore, the covering member 101 that can be easily attached to the mating member 109 and can be manufactured at low cost is desired.

  The covering member of the present invention preferably includes any of the following (1) to (7), and more preferably includes a plurality of (1) to (7).

(1) Having a second ring member made of a metal spring material and having a ring shape with ends,
The second mounting portion has an annular groove-shaped second engagement groove that engages with a peripheral edge portion of the first opening,
The groove wall of the second engagement groove is located on the second facing surface side and accommodates the second ring member in the second attachment state in which the second engagement groove engages with the peripheral edge of the second opening. A second opposing wall portion having an annular groove-shaped second ring groove, and a second claw portion located on the second back surface side in the second attached state,

  (7) The second opposing wall portion has a second opposing seal portion that protrudes toward the second claw portion and has a pointed shape.

  In the covering member of the present invention, a member made of a metal spring material is used as the first ring member for suppressing the detachment of the first attachment portion from the peripheral edge portion of the first opening. For this reason, the covering member of the present invention can be manufactured at low cost.

  Moreover, the 1st attaching part in the coating | coated member of this invention has a 1st nail | claw part. For this reason, the 1st attaching part in the coating | coated member of this invention can be easily attached to the peripheral part of 1st opening. This is due to the following reason.

  The first claw portion is located in the first attachment portion in the first attachment state (that is, the first engagement groove of the first attachment portion engages with the peripheral edge portion of the first opening) than the first opening. It is formed in a portion located on the second opening side (that is, the back side from the first opening). Further, in the first attachment state, the first claw portion protrudes toward the peripheral portion of the second panel side surface (first opposing surface) of the first panel. For this reason, the first claw portion that is elastically deformed in the compression direction when the first attachment portion is attached to the peripheral portion of the first opening returns (expands) to the original shape when passing through the first opening.

  When the first claw portion returns elastically, vibration occurs. Therefore, the operator who attaches the covering member of the present invention to the counterpart member can perceive the completion of the attaching operation by touch or the like.

  The first claw portion easily passes through the first opening in order to form a taper shape. Therefore, the first attachment portion can be easily attached to the peripheral portion of the first opening despite having the first claw portion. Furthermore, since the first claw portion is tapered, the axial force when the first attachment portion is pressed toward the first opening can be converted into the force in the direction in which the first claw portion is reduced in diameter. Also by this, the 1st attaching part can be easily attached to the peripheral part of the 1st opening. Furthermore, since the first claw portion has a thick portion, it also functions as a reinforcing rib for the first attachment portion.

  According to the covering member of the present invention provided with the above (1), the second attachment portion can be easily attached to the peripheral portion of the second opening by providing the second attachment portion with the second claw portion.

  According to the covering member of the present invention including any one of the above (2), (4), and (5), the first attachment portion can be attached to the peripheral portion of the first opening in the first panel with high sealing performance.

  According to the covering member of the present invention provided with any one of the above (3), (6), and (7), the second attachment portion can be attached to the peripheral portion of the second opening in the second panel with high sealing performance.

  The contact part 50 is integrated with the back end part of the second attachment part 30 (specifically, the back end part of the second claw part 33), and protrudes inward. When the covering member 1 according to the first embodiment is attached to the mating member 9, the contact portion 50 comes into elastic contact with the surface of the inlet filler pipe 99.

  A procedure for attaching the covering member 1 of the first embodiment to the mating member 9 will be described below.

  First, the first ring member 81 is accommodated in the first ring groove 25 of the first attachment portion 20 (first back wall portion 22) while being elastically deformed (reduced diameter). The first ring member 81 accommodated in the first ring groove 25 attempts to elastically return (expand the diameter) to the original shape. Since the first ring groove 25 has a smaller diameter than the first ring member 81 in the natural state, the first ring member 81 accommodated in the first ring groove 25 extends in the direction in which the diameter of the first back wall 22 is increased. Press.

  Similarly, the second ring member 82 is accommodated in the second ring groove 35 of the second attachment portion 30 (second opposing wall portion 32) while being reduced in diameter by elastic deformation. The second ring member 82 accommodated in the second ring groove 35 presses the second opposing wall portion 32 in the direction of expanding the diameter.

  Next, as shown in FIG. 2, the covering member 1 according to the first embodiment is disposed on the near side of the first panel 91 while the first attachment portion 20 faces the near side and the second attachment portion 30 faces the far side. . Then, the covering member 1 is pushed in from the near side to the far side while the second attachment portion 30 is inserted into the first opening 95.

  Then, as shown in FIG. 3, the first claw portion 23 of the first mounting portion 20 gets over the first opening 95 while being elastically deformed, and the first opposing surface from the first back surface 94 side of the first panel 91. It is pushed into the 95 side. Similarly, the second claw portion 33 of the second attachment portion 30 gets over the second opening 98 while being elastically deformed, and is pushed from the second back surface 96 side of the second panel 92 to the second back surface 97 side. .

  When the covering member 1 is pushed into the position where the first claw 23 passes through the first opening 95, the first engagement groove 21 is engaged with the peripheral edge of the first opening 95. Then, the first claw portion 23 is elastically restored and comes into contact with the peripheral edge portion of the first opening 95 in the first facing surface 93. When the first claw portion 23 returns elastically, vibration occurs. Therefore, the operator can perceive by touch or the like that the mounting operation of the first mounting portion 20 on the first panel 91 (specifically, the peripheral edge portion of the first opening 95) is completed.

  Similarly, when the covering member 1 is pushed into a position where the second claw portion 33 passes through the second opening 98, the second engagement groove 31 engages with the peripheral edge portion of the second opening 98. Then, the second claw 33 is elastically restored and comes into contact with the peripheral edge of the second opening 98 in the second back surface 97. When the second claw 33 is elastically restored, vibration is generated. Therefore, the worker can perceive that the attaching operation of the second attaching portion 30 to the second panel 92 (specifically, the peripheral edge portion of the second opening 98) is completed by touch or the like. Therefore, the covering member 1 of Example 1 can be easily and reliably attached to the counterpart member 9.

  In the first attachment state in which the first engagement groove 21 is engaged with the peripheral edge of the first opening 95, the first back wall portion 22 is located on the first back surface 94 side of the first panel 91. . Therefore, the first back seal portion 26 is in elastic contact with the peripheral edge portion of the first opening 95 in the first back surface 94. At this time, the first ring member 81 presses the first back wall portion 22 in the direction of expanding the diameter. By expanding the diameter by the first ring member 81, the first back seal portion 26 of the first back wall portion 22 is in pressure contact with the first back surface 94 of the first panel 91. In other words, the seal surface pressure with respect to the first back surface 94 of the first back seal portion 26 is increased by the first ring member 81. For this reason, the first attachment portion 20 is attached to the peripheral edge portion of the first opening 95 in the first panel 91 with high sealing performance.

  In the first attachment state, the first claw portion 23 is located on the first facing surface 93 side of the first panel 91. For this reason, the first claw portion 23 protrudes toward the peripheral edge portion of the first facing surface 93. The first opposing seal portion 27 provided on the first claw portion 23 is in elastic contact with the first opposing surface 93 of the first panel 91. The first back seal portion 26 is in elastic contact with the peripheral portion of the first opening 95 in the first back surface 94, and the first counter seal portion 27 is in elastic contact with the peripheral portion of the first opening 95 in the first counter surface 93. Thus, the first attachment portion 20 is attached to the peripheral portion of the first opening 95 without a gap. Therefore, according to the covering member 1 of the first embodiment, it is possible to reliably suppress the intrusion of foreign matters (water, dust, mud, etc.) from the near side to the far side of the first opening 95.

  In the second attachment state in which the second engagement groove 31 engages with the peripheral edge portion of the second opening 98, the second opposing wall portion 32 is positioned on the second opposing surface 96 side of the second panel 92. For this reason, the second opposing seal portion 36 is in elastic contact with the peripheral edge portion of the second opening 98 in the second opposing surface 96. At this time, the second ring member 82 presses the second opposing wall portion 32 in the direction of expanding the diameter. The second opposing seal portion 36 of the second opposing wall portion 32 is in pressure contact with the second opposing surface 96 of the second panel 92 by being expanded in diameter by the second ring member 82. In other words, the seal surface pressure of the second facing seal portion 36 against the second facing surface 96 is increased by the second ring member 82. For this reason, the second attachment portion 30 is attached to the peripheral portion of the second opening 98 in the second panel 92 with high sealing performance.

  In the second attachment state, the second claw portion 33 is located on the second back surface 97 side of the second panel 92. For this reason, the second claw portion 33 protrudes toward the peripheral edge portion of the second back surface 97. The second back seal portion 37 provided on the second claw portion 33 is in elastic contact with the second back surface 97 of the second panel 92. The second opposing seal portion 36 is in elastic contact with the peripheral portion of the second opening 98 in the second opposing surface 96, and the second back seal portion 37 is in elastic contact with the peripheral portion of the second opening 98 in the second back surface 97. Thus, the second attachment portion 30 is attached to the peripheral portion of the second opening 98 without any gap. Therefore, according to the covering member 1 of the first embodiment, it is possible to reliably suppress the intrusion of foreign matters from the back side of the second opening 98 toward the front side. Moreover, since the 2nd opposing seal | sticker part 36 protrudes toward the base end part of the 2nd nail | claw part 33, the foreign material (especially liquid substances, such as water) toward the near side from the back side of the 2nd opening is used. Ingress can be suppressed particularly reliably.

  Furthermore, according to the covering member 1 of the first embodiment, the second attachment member 30 is attached to the peripheral portion of the second opening 98 without pushing the second ring member 82 into the back side of the second opening 98, so that the covering member There is also an advantage that the attaching work to one mating member 9 becomes very easy and the attaching work efficiency is improved.

  Furthermore, the first claw portion 23 and the second claw portion 33 are tapered. For this reason, the 1st attaching part 20 gets over the 1st opening 95 easily. Further, the second attachment portion 30 easily gets over the second opening 98. Also by this, the coating | coated member 1 of Example 1 is excellent in attachment work efficiency.

  In the covering member 1 of the first embodiment, in the second attachment state, the second ring member 82 is disposed on the second facing surface 96 side of the second panel 92, and the second claw portion 33 is disposed on the second panel. 92 on the second back surface 97 side. For this reason, the sealing surface pressure with respect to the second back surface 97 of the second mounting portion 30 is smaller than the sealing surface pressure with respect to the first back surface 94 of the first mounting portion 20. However, since the second back-facing seal portion 37 is continuously formed over the entire circumference of the second claw portion 33, the intrusion of foreign matters from the back side to the near side of the second opening 98 can be reliably suppressed. .

(Example 2)
The covering member of Example 2 is the same as the covering member of Example 1 except for the shape of the first attachment portion and the shape of the second attachment portion.
