(2-2) position of mounting hole has produced the situation of error
Followingly the effect of the each several part owing to having produced that error has been offset mounting hole 5 when when location or the perforate is described with reference to Fig. 7.For convenience of explanation, in Fig. 7, mounting hole 5 is described from the situation that assigned position is offset to the left side.And L1 is the center line of mounting hole 5 of expression assigned position among the figure, and L2 is the center line of the mounting hole 5 that has been offset.In addition, before being installed in mounting grommet 1 on the vehicle body 2,, omit its explanation for the sake of simplicity with above-mentioned same.
At first, externally the situation of hole seat 6 absorption errors describes.Because cylindrical part 11 has the gap with respect to mounting hole 5, so can be offset the amount in this gap.In addition, because mounting hole 5 is departing from assigned position, during butt, return projection 15 is mounted the inner edge pushing in hole 5 on the inner edge of return projection 15 and mounting hole 5.Thus, in return projection 15 with before cylindrical part 11 outer surfaces contact, Yi Bian the 1st fastening sheet 13 is toppled over to the inside, Yi Bian mounting grommet 1 is moved (Fig. 7 (A)) to the right.So,, move 1 (mm) by outer hole seat 6 along the radially maximum of mounting hole 5, thereby can easily bolt 3 be inserted in the endoporus seat 7 even when mounting hole 5 departs from assigned position, can be reliably fixing spoiler 4.
In addition, even hole seat 6 moves to the outer surface position contacting of return projection 15 and cylindrical part 11 outside,, come off so can prevent mounting grommet 1 because the 1st blocked part 12 and supporting surface 14 clip vehicle body 2.
Below the situation of endoporus seat 7 absorption errors is described.Because the 2nd fastening sheet 21 has the gap with respect to the internal diameter of cylindrical part 11, so can be offset the amount corresponding to this gap.That is, when assigned position had been offset to the left, before the inwall 11a butt of the outer surface of the 2nd foot 24 and cylindrical part 11, endoporus seat 7 moved to the right at mounting hole 5.So,, move 2 (mm) by endoporus seat 7 along the radially maximum of mounting hole 5, thereby can easily bolt 3 be inserted in the endoporus seat 7 even when mounting hole 5 departs from assigned position, can be reliably fixing spoiler 4.
In addition, outer hole seat 6 and endoporus seat 7 can move with respect to the error interlock that produces respectively.That is, as shown in Figure 8, move to equidirectional by outer hole seat 6 and endoporus seat 7, so, even when bigger error has appearred in the position of mounting hole 5, by making maximum altogether 3 (mm) of moving of outer hole seat 6 and endoporus seat 7, and can absorb this error, can keep spoiler 4 reliably.
As mentioned above, at present embodiment, mounting grommet 1, when the position of mounting hole 5 had produced error, by pushing bolt 3, above-mentioned outer hole seat 6 and above-mentioned endoporus seat 7 can be distinguished radially mobile, so, can absorb bigger error, therefore can increase work efficiency.In addition and since make 20 fastenings of the 2nd blocked part in fastening on the 1st blocked part 12 on the outer edge of a side of mounting hole 5, focus on the endoporus seat 7 so can prevent axial stress, can prevent that endoporus seat 7 from coming off.
In addition, owing to have the 3rd blocked part 31,32 that above-mentioned endoporus seat 7 is remained on the axial central authorities of above-mentioned outer hole seat 6, so can and outer hole seat 6 between be provided with the gap endoporus seat 7 remain on the central authorities of mounting hole 5, therefore inserting bolt 3 easily can further be increased work efficiency.
In addition, because the lower surface in above-mentioned the 1st blocked part 12 and above-mentioned the 2nd blocked part 20 is respectively equipped with sealing component 8, so can make vehicle body 2 keep watertight.
2. the 2nd mode of execution
Followingly the 2nd mode of execution of the present invention is described, to the identical reference character of part mark corresponding among Fig. 9 with Fig. 1 with reference to Fig. 9.And mounting grommet 40 shown in Figure 9 is that with the difference of above-mentioned the 1st mode of execution the 1st diaphragm seal 41 and prominent bar 42 and the 2nd diaphragm seal 43 form as one with outer hole seat 6 and endoporus seat 7.
That is, the 1st blocked part 12 of outer hole seat 6 has the abutment portion of sealing outer hole seat 6 and vehicle body 2 and anti-sealing and enters into the 1st interior diaphragm seal 41 of vehicle body 2.The 1st blocked part 12 to be to surround the mode of mounting hole 5, makes outer circumference end tilt and form the 1st diaphragm seal 41 to a side 2a of mounting hole 5, its front end have can with the sealing surface 41a of a side butt of mounting hole 5.The 1st diaphragm seal 41 forms the gap delta that forms between the upper end 13t of sealing surface 41a and the 1st fastening sheet 13 littler than the thickness of slab t of vehicle body 2.In addition, the 1st diaphragm seal 41 can be pressed by a thruster of vehicle body 2 and be out of shape on being installed in vehicle body 2 time, and the 1st diaphragm seal 41 angle [alpha] with respect to the horizontal plane is a predetermined angular, for example is 45 degree.So, the 1st diaphragm seal 41 owing to sealing surface 41a forms periphery circular, encirclement mounting hole 5, enters in the vehicle body 2 from the abutment portion of outer hole seat 6 with vehicle body 2 so can prevent sealing.
The 2nd blocked part 20 of endoporus seat 7 has the abutting part of sealing endoporus seat 7 and spoiler 4 and assigns to prevent that water from entering into the 2nd diaphragm seal 43 in the vehicle body 2.The 2nd blocked part 20 to surround the mode of through hole, makes outer circumference end tilt and form the 2nd diaphragm seal 43 to the surperficial 4a of spoiler 4, its front end have can with the sealing surface 43a of the surperficial 4a butt of spoiler 4.It is more outstanding upward with surperficial 20b spoiler 4 butts than the 2nd blocked part 20 that the 2nd diaphragm seal 43 forms sealing surface 43a.In addition, the 2nd diaphragm seal 43, in order to be out of shape by the surperficial 4a pushing of spoiler 4 when spoiler 4 is installed, the 2nd diaphragm seal 43 angle beta with respect to the horizontal plane is a predetermined angular, for example is 45 degree.And, the 2nd diaphragm seal 43, because sealing surface 43a forms ring, so, can surround the periphery of through hole 22 and anti-sealing enters into vehicle body 2 from the abutment portion of endoporus seat 7 and spoiler 4.
And the 1st diaphragm seal 41 and the 2nd diaphragm seal 43 form can resiliently deformable under Axial Loads.
In addition, outer hole seat 6 is formed with the abutment portion of sealing the 1st blocked part 12 and the 2nd blocked part 20 and anti-sealing enters into the prominent bar 42 in the vehicle body 2 on the 1st blocked part 12.Prominent bar 42 form the surperficial 12a that makes with the 1st blocked part 12 of the 2nd blocked part 20 butts bulge into circular, in the upper end can with the inside butt of the 2nd blocked part 20.So, owing to making surperficial 12a bulge into circular and forming continuous prominent bar 42, so mounting grommet 40 can seal the superimposed portion of outer hole seat 6 and endoporus seat 7, anti-sealing enters in the vehicle body 2.Therefore, prominent bar 42 relative through holes 22 are concentric circles, are formed with a plurality ofly, for example are formed with 2.And it is 1 that mounting grommet 40 can certainly make prominent bar 42.

In addition, mounting grommet 40 is because the bar 42 of will dashing forward is arranged on the abutment portion of the 1st blocked part 12 and the 2nd blocked part 20, so can make the responsive to axial force that produces when being fixed on spoiler 4 on the vehicle body 2 on prominent bar 42.Therefore, mounting grommet 40 is pressed against on the surperficial 20a by the bar 42 of will dashing forward powerfully, so can improve sealability, anti-sealing enters in the vehicle body 2 reliably.
In addition, mounting grommet 40 is because the bar 42 of will dashing forward forms ring, so, even endoporus seat 7 radially moves with respect to outer hole seat 6, also can keep sealability.
In addition, mounting grommet 40, because the 1st diaphragm seal 41 and the 1st blocked part 12 are formed as one, the 2nd diaphragm seal 43 and the 2nd blocked part 20 are formed as one, so can make the responsive to axial force that when being fixed on spoiler 4 on the vehicle body 2, produces on prominent bar 42.Therefore, mounting grommet 40, because powerful ground is pressed against sealing surface 41a on the one side 2a of vehicle body 2, sealing surface 43a is pressed against on the surperficial 4a of spoiler 4 also powerfully, thereby can improves sealability, anti-sealing enters in the vehicle body 2 reliably.
In addition, mounting grommet 40, owing to the 1st diaphragm seal 41 is surrounded the outer edge of a side 2a of above-mentioned mounting hole 5, and the 2nd diaphragm seal 43 is surrounded through hole 22, so even outer hole seat 6 radially moves, also has with respect to through hole 22, even endoporus seat 7 radially moves with respect to outer hole seat 6, also can keep sealability.
In addition, owing to being constituted as, mounting grommet 40 make the 1st diaphragm seal 41 and 43 distortion of the 2nd diaphragm seal press to the structure of vehicle body 2 and spoiler 4, so the thickness of the part that a side 2a that can make at vehicle body 2 is outstanding reduces.Therefore, adopt mounting grommet 40 can reduce design limit, be convenient to improve commodity.
In addition, owing to being constituted as, mounting grommet 40 make the 1st diaphragm seal 41 and 43 distortion of the 2nd diaphragm seal press to the structure of vehicle body 2 and spoiler 4, so can improve the performance of being obedient to curved surface.Therefore mounting grommet 40 even have under the situation of curved surface at vehicle body 2 and spoiler 4, can prevent reliably that also sealing enters in the vehicle body 2.
In addition, mounting grommet 40, owing to can make the 1st diaphragm seal 41 and 43 distortion of the 2nd diaphragm seal, so can absorb the impact that is applied on the spoiler 4.Therefore, mounting grommet 40 can prevent the damage of spoiler 4, can improve the durability of spoiler 4.
In addition and since prominent bar 42 with respect to through hole 22 for concentric circles and form a plurality ofly, for example form 2, so, even the occasion that radially is offset of hole seat 6 and endoporus seat 7 outside also can seal, can prevent reliably that sealing enters in the vehicle body 2.
