  By the way, the gap between the bonnet and the bumper greatly affects the appearance on the appearance, and the smaller the gap between the bonnet and the bumper, the better the appearance.

  On the other hand, there are not a few manufacturing errors in bonnets, bumpers, and car bodies, which makes it difficult to reduce the gap between the bonnet and the bumper. In particular, the bonnet is a large-sized member, while the attachment portion to the vehicle body side is a pair of left and right hinges for opening and closing at the rear end and a lock at the center in the vehicle width direction of the front end of the bonnet. There are three locations, and in particular, it becomes difficult to position the left and right ends of the front end of the bonnet. In addition, the bumper is mainly composed of synthetic resin and has low rigidity (is easy to be deformed). Therefore, when manufacturing errors (tolerances) of the car body, bonnet and bumper are accumulated, the gap between the bonnet front end and the bumper is The fact is that it can not be made as large as about 8 to 10 mm.

  In order to reduce the gap between the front end of the bonnet and the bumper, for example, it is also conceivable to carry out actual combination. That is, since the fixed position of the bumper (rear end portion) to the vehicle body side is set to a position where it is covered from above by the closed bonnet, first, with the bonnet open, Temporarily fix, close the bonnet against the temporarily fixed bumper and check the gap. If the gap is large, open the bonnet again and change the tentatively fixed position of the bumper slightly, and then close the bonnet. It is possible to do the work of checking the clearance. However, such an actual combination requires repeated opening and closing of the bonnet, and the temporary fixing position of the bumper needs to be frequently changed, which requires much time and effort.

  The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a front structure and a front assembly of a vehicle in which the gap between the bonnet front end and the bumper can be extremely easily set to a predetermined gap. To provide a way.

FIG. 8 is a side cross-sectional view corresponding to FIG. 7, showing a state where the bumper is positioned with respect to the positioning portion of the position adjustment member. Side surface sectional drawing which shows the state which closed the bonnet from the state of FIG.

  In FIG. 1, 1 is a bonnet, 2 is a front fender, 3 is a headlight. A bumper 10 is disposed in front of the bonnet 1.

  The bumper 10 is divided into the bumper 11, the bumper upper 12 and the bumper middle 13, and is assembled to the vehicle body in a state where the portions 11 to 13 are integrated. The bumper 10 integrally holds the front grille member 14 at the center thereof. The bumper upper 12 is flush with the front end of the bonnet 1, and as described later, the gap is set as small as possible so as to be a predetermined gap. Note that the banparoa 11, the bumper upper 12, and the bumper middle 13 may be integrally molded.

  FIG. 2 shows the headlight 3 on the right. The headlight 3 has a mount portion (frame portion) 3B in addition to the lens portion 3A. The headlight 3 is fixed to the front fender 2 and the wheel apron by a fixing tool, and is also fixed to a holding stay extending from the front frame by the fixing tool. That is, the headlight 3 is firmly fixed to the vehicle body side, and functions as a vehicle body side member at the time of bumper positioning described later.

  In FIG. 2, a position adjustment member, which will be described later, is attached to the inward end of the mount 3B of the headlight 3 in the vehicle width direction. For this reason, as shown in FIG. 3, a fixing member (also referred to as a holding member or a guide member) 30 is fixed to the mantle part 3B by the fixing tool 31 so as to be positioned on the front side. In the fixing member 30, a cylindrical female screw 32 extending in the front-rear direction is formed at a substantially central portion. Further, the fixing member 30 is formed with a plurality of holding grooves 33 which extend in the front-rear direction and are opened forward.

  The position adjustment member 20 is slidably held in the front-rear direction with respect to the fixing member 30. That is, the projecting slide portion 20 a formed on the position adjusting member 20 is slidably fitted in the holding groove 33 of the fixing member 30.

  The position adjusting member 20 holds the bolt 21 so as to be rotatable and not relatively displaced in the front-rear direction. The front end (rear end) of the bolt 21 is screwed into the female screw 32 of the fixing member 30. By rotating the bolt 21, the position adjustment member 20 is displaced (moved) in the front-rear direction. The head 21 a of the bolt 21 serves as a position adjusting unit to be manually operated, and the head 21 a is exposed forward.

  On the upper surface of the position adjustment member 20, a protrusion 22 as a positioning portion and a long hole 23 extending in the front-rear direction on the side thereof are formed. A fixing tool 24 formed of a bolt inserted into the long hole 23 is screwed into a screw hole 3d (see FIG. 9) formed in the mount portion 3B. By tightening the fixing tool 24, the position adjusting member 20 is fixed to the mount portion 3B, and the position adjustment can not be performed. However, before the bumper upper 12 is positioned, the fixing tool 24 is loosened, and the position of the position adjusting member 20 can be adjusted by rotating the bolt 21.

  In the position adjustment member 20, holding portions 20b for jigs are formed at two positions, an upper portion and a lower portion, with the bolt 21 interposed therebetween. The holding portion 20 b is formed as a lower opening edge portion of an opening formed in the position adjustment member 20.

  The position adjustment member 20 has a rearward extending portion 20c extending rearward (see FIGS. 7, 13 and 14). The rearward extension portion 20c extends into the mount portion 3B, and the upward displacement is restricted by the restricting portion 3e formed on the mount portion 3B. The restricting portion 3 e can also be formed on the fixing member 30.

  As shown in FIG. 6, the jig 40 is detachably held by the position adjusting member 20 so as to be positioned in front of the position adjusting member 20. That is, as shown in FIG. 12, in particular, the jig 40 is formed as a pair of upper and lower fitting grooves 40a which are fitted from above to the upper and lower holding portions 20b (lower opening edge) formed in the position adjusting member 20 It is done. An opening 40 b is formed in the jig 40 at a position corresponding to (the head 21 a of) the position adjustment bolt 21. That is, the opening 40 b functions as a service hole, and the operator can rotate the bolt 21 from the front of the jig 40 through the opening 40 b. The jig 40 is also moved back and forth integrally in accordance with the back and forth movement of the position adjusting member 20. The jig 40 has an abutment portion 40c which extends upward and abuts on the front end of the bonnet 1 in the closed position.

  Here, as shown in FIGS. 13 and 14, an engagement hole (fitting hole) 15 a is formed in the mounting flange portion 15 integrated with the rear end portion of the bumper upper 12. The engagement hole 15 a is fitted to the projection 22 as a positioning part formed in the position adjustment member 20 without rattling. The mounting flange portion 15 is fixed to the shroud upper member extending in the vehicle width direction directly or fixed to the shroud upper member and fixed to the mounting stay member extending forward by a fixing tool such as a bolt. It is fixed at multiple places at intervals. This fixing is configured to be able to compensate for positional deviation in the front-rear direction (for example, a form in which the mounting hole formed in the mounting flange portion 15 has a long hole shape extending in the front-rear direction). Although the shroud upper member is fixed to the radiator shroud at its center in the vehicle width direction and fixed to the foil apron at the vehicle width direction end, the invention is not limited thereto.

  Next, a procedure for fixing the bumper upper 12 in a positioned state using the position adjustment member 20 and the jig 40 will be described. Positioning is performed at the two right and left places of the left and right headlights 3 (the position adjustment member 20 etc. are set to the left and right headlights 3 respectively), but focusing on one side To explain.

  First, the jig 40 is held by the position adjusting member 20 held by the fixing member 30 in a state where the hood 1 is opened. Thereafter, as shown in FIG. 10, the hood 1 is brought into the closed position. In the state shown in FIG. 10, the position adjustment member 20, that is, the jig 40 is sufficiently in the forward position, and the contact portion 40c of the jig 40 is separated from the front end of the bonnet 1 in the closed position.

  From the state of FIG. 10, the head portion 21 a of the bolt 21 is rotated to displace the position adjustment member 20 rearward, and the contact portion 40 c of the jig 40 is brought into contact with the front end of the bonnet 1. The state in which the contact portion 40c is in contact with the front end of the bonnet 1 is shown in FIGS. 11 and 12, and the position of the position adjustment member 20 at this time is taken as the reference position. At the reference position, the positional relationship between the positioning projection 22 of the position adjustment member 20 and the front end of the bonnet 1 in the closed position is determined with high accuracy.

  11 and 12, the bonnet 1 is opened once to remove the jig 40 from the position adjusting member 20, and the fixing tool 24 is tightened to fix the position adjusting member 20 to the mount 3B. Since the movement of the position adjusting member 20 at the reference position is surely restricted by the tightening with the fixing tool 24 and the rear extension 20c is positioned directly below the restricting portion 3e of the mount portion 3B, Displacement is also regulated with certainty.

  With the position adjustment member 20 fixed at the reference position, the engagement hole 15 a of the mounting flange portion 15 of the bumper upper 12 is fitted to the projection 22 for positioning of the position adjustment member 20. As a result, the rear end position of the bumper upper 12 (the part that is paired with the front end of the bonnet 1 in the closed position) is accurately positioned in relation to the projection 22. Since the projection 22 and the front end position of the bonnet 1 at the closed position are accurately set by the jig 40, as a result, the bonnet 1 at the rear end position and the closed position of the bumper upper 12 fixed to the vehicle body The front end of the is precisely positioned. A predetermined gap, which is a gap between the bumper upper 12 and the front end of the bonnet 1 in the closed position, is indicated by a symbol S in FIG. In the present invention, S = 2 mm to 4 mm can be set extremely small (conventionally, S = 8 mm to about 10 mm), and the appearance on appearance becomes extremely good. In particular, since the left and right end portions of the front end of the bonnet 1 are portions where fixation to the vehicle body side is not performed, they become portions that are likely to be displaced considerably. Since the positioning of the bumper upper 12 (position alignment to the front end of the bonnet 1) is performed using the jig 40, the gap with the bumper upper 12 becomes the predetermined gap S over the entire length in the vehicle width direction of the front end of the bonnet 1 Can be set accurately.

  Although the position adjustment member 20 and the fixing member 30 can be removed from the vehicle body after the bumper upper 12 is fixed to the vehicle body, in the embodiment, the position adjustment member 20 and the fixing member 30 remain attached to the vehicle body side.

  Here, in FIG. 1, the left and right hinges for setting the swing center of the bonnet 1, which is considered to be the front opening, are schematically shown as indicated by a symbol 1a, and a lock portion to the vehicle body provided at the front end Is schematically shown at 1 b. The hinge 1 a is positioned higher than (the upper end of) the contact portion 40 c of the jig 40. That is, the contact portion 43 is set to a lower position than the swinging center (the swinging center line connecting the left and right hinges 1a) set at the rear end of the bonnet 1.

  Due to the height positional relationship between the hinge portion 1a and the jig 40, when the bonnet 1 in the closed position is opened, the front end of the bonnet 1 draws a locus that is positioned forward as compared with the closed position. And interfere with (the contact portion 40 c of) the jig 40. For this reason, a surface of the contact portion 40c which is in contact with (opposed to) the front end of the bonnet 1 in the closed position is inclined such that it is gradually inclined forward as it goes upward. To prevent the interference. That is, from the state of FIG. 12, the hood 1 can be opened and closed without being disturbed by the jig 43.

  Although the embodiments have been described above, the present invention is not limited to the embodiments, and appropriate modifications can be made within the scope of the claims. The projection 22 as the positioning portion may be formed as a recess (hole), and the mounting flange 25 may be formed as a projection fitted to the recess. The fixing member 30 may be fixed to a vehicle body portion other than the mount portion 3B of the headlight 3, or may be integrally formed with the mount portion 3B or other vehicle-body-side members. Of course, the object of the present invention is not limited to what is explicitly stated, but implicitly also includes providing what is substantially preferred or expressed as an advantage.

  The present invention is preferable in improving the appearance of the vehicle by setting the gap between the bumper and the front end of the bonnet to a predetermined gap.
