  FIG. 1 is a perspective view of a gap adjusting shim according to the present embodiment, and FIG. 2 is a perspective view showing a state in which the gap adjusting shim according to the present embodiment is attached to an attached portion of a hood hinge.

  The present embodiment is an example in which the gap adjusting shim according to the present invention is applied to the adjustment of the gap with the vehicle body when the hood hinge is assembled.

  As shown in FIGS. 1 and 2, the gap adjusting shim 1 of the present embodiment is attached to a mounted portion 2 of a hood hinge that is a mounted member, and is formed on the mounted portion 2 via a washer 3. It is fixed with a bolt 5 inserted into the bolt through hole 4.

  The gap adjusting shim 1 is disposed on the one surface 2a side of the mounted portion 2 and is folded upward from one end surface 6a of the shim portion 6 and disposed on the other surface 2b side of the mounted portion 2. A first folded portion 7 and a second folded portion 8 which is further folded upward at the tip of the first folded portion 7 and sandwiches the mounted portion 2 with the shim portion 6.

  The shim portion 6 is a plate having a rectangular shape in plan view having a thickness suitable for adjusting the gap, and is provided in close contact with the one surface 2 a of the attached portion 2. The shim portion 6 is formed with a hole portion 9 that communicates with the bolt through hole 4 formed in the attached portion 2. The bolt 5 is inserted into the hole 9.

  The first folded portion 7 has two bent portions 7A and 7A that extend forward from one end face 6a of the shim portion 6 and then bend so as to rise substantially vertically upward at both ends of the shim portion 6. In addition, there are two folded pieces 7B and 7B extending from the ends of the bent portions 7A and 7A toward the other end face 6b side of the shim portion 6 respectively.

  The bent portions 7A and 7A have a reduced cross section having a cross sectional area S2 smaller than the cross sectional area S1 at a position parallel to the one end face 6a of the shim portion 6. The bent portions 7 </ b> A and 7 </ b> A protrude from the one end surface 6 a of the shim portion 6 by a predetermined amount L and are folded back. The amount L for projecting the bent portions 7A and 7A from the one end surface 6a of the shim portion 6 is preferably about 2 mm or more so that the bent portions 7A and 7A can be easily bent.

  The folded piece portions 7B and 7B extend from the front ends of the bent portions 7A and 7A rising substantially vertically toward the other end face 6b side of the shim portion 6, and the front end portions are in contact with or close to the shim portion 6. Is so inclined. The two folded piece portions 7B and 7B are formed in an elongated arm shape, and exert a clamping force for gripping the attached portion 2 by being elastically applied by the bent portions 7A and 7A.

  An opening 10 corresponding to the hole 9 formed in the shim 6 is formed between the two folded pieces 7B and 7B. The opening 10 is an opening having a rectangular shape in plan view that does not come into contact with the bolt 5 and does not drop off the washer 3.

  The second folded portion 8 is provided by connecting the tips of the two folded piece portions 7B and 7B. The second folded portion 8 functions as a clip portion that sandwiches the mounted portion 2 with the shim portion 6 by being folded back obliquely upward from the tip of the two folded piece portions 7B, 7B. The distal end portion 10a of the opening portion 10 is set to a position offset to the one end face 6a side of the shim portion 6 by a predetermined amount with respect to the folding line 11 that is the folding position of the second folding portion 8. That is, a flat portion 12 having a predetermined width is provided between the distal end portion 10 a of the opening portion 10 and the broken line 11. The offset amount is preferably about 1 mm or more in consideration of molding stability and bending rigidity in the vicinity of the broken line when the second folded portion 8 is folded.

  The gap adjusting shim 1 configured as described above is attached by inserting the attached portion 2 of the hood hinge into the gap between the shim portion 6 and the first folded portion 7 and the second folded portion 8. At this time, since the second folded portion 8 is inclined obliquely upward, it is easy to insert the attached portion 2 into the gap. Moreover, the 1st folding | turning part 7 and the 2nd folding | turning part 8 are lifted upward when the to-be-attached part 2 approachs into the said clearance gap, and hold down the to-be-attached part 2 with the reaction force. The gap adjusting shim 1 is clamped to the attached portion 2 by the elastic force of the first folded portion 7 and the second folded portion 8. The gap adjusting shim 1 is fixed to the mounted portion 2 by being tightened with a bolt 5 via a washer 3.

  According to the gap adjusting shim 1 of the present embodiment, the shim portion 6, the first folded portion 7 formed by folding back from the one end face 6 a of the shim portion 6, and the tip of the first folded portion 7 are further moved upward. Since the attached portion 2 of the hood hinge is sandwiched and fixed by the folded second folded portion 8, it can be attached by simply inserting it into the attached portion 2, and the latching claw can be hooked. The shim portion 6 is not deformed unlike the conventional structure attached to the mounted portion 2.

  Further, according to the gap adjusting shim 1 of the present embodiment, the bent portions 7A and 7A of the first folded portion 7 are reduced in cross section smaller than the cross-sectional area S1 of the shim portion 6, and therefore the bent portions 7A and 7A. The bending rigidity of the sheet is lowered and it is easy to turn. Therefore, according to this embodiment, the stable shape of bending part 7A, 7A is securable. On the other hand, when it is bent at the site of the cross-sectional area S1, it becomes difficult to bend because the bending rigidity is increased.

  Further, according to the gap adjusting shim 1 of the present embodiment, the bent portions 7A and 7A are formed by projecting a predetermined amount from the one end surface 6a of the shim portion 6 so as to be folded back. It is possible to ensure the flatness of the end portion at. Thereby, the shim part 6 and the to-be-attached part 2 can be closely_contact | adhered, and it can prevent rising and becoming more than shim thickness.

  Further, according to the gap adjusting shim 1 of the present embodiment, two tips of the first folded portions 7 and 7 are connected to both ends of the second folded portion 8, so that two The first folded portion 7 opens in a stable state. Therefore, the gap adjusting shim 1 improves the mounting workability and provides a stable clip holding effect.

  Further, according to the gap adjusting shim 1 of the present embodiment, the tip of the opening 10 is set at a position offset by a predetermined amount with respect to the folding line 11 that is the folding position of the second folding part 8. As the bending rigidity in the vicinity of the broken line 11 increases during the folding, the shape of the second folded portion 8 is stabilized. With this stable shape of the second folded portion 8, it is possible to stabilize the clamping strength for sandwiching the mounted portion 2 with the shim portion 6.

  Further, according to the gap adjusting shim 1 of the present embodiment, since the hole 9 is provided in the portion corresponding to the opening 10 of the shim 6, the washer 3 can be placed in the hole 9 through the opening 10. The opening portion 10 fulfills a guiding function for guiding the washer 3 to the hole 9, so that the workability of fastening the bolt 5 inserted into the hole 9 is improved and the assembling property of the washer 3 is improved.
