[Problems to be solved by the invention]
However, in the holding structure disclosed in JP-A-2001-1758, the elastic claw pieces can be bent in the inner diameter direction by inserting the elastic claw pieces into the slits formed in the stem. Since it is necessary to provide gaps for die cutting on both sides of the elastic claw, the width of the elastic claw is narrowed relative to the inner widthwise direction of the slit, so that the elastic claw is It was necessary to provide a predetermined gap between both sides of the piece and the inner wall in the width direction of the slit.
[0006]
For this reason, even if the first projection formed on the outer surface of the free end of the elastic claw is engaged with the recess provided at the hole edge of the mounting hole to prevent the holder from rotating with respect to the mounting hole, Since the elastic claw pieces can move within the slit by the gap provided between both sides of the piece and the inner wall in the width direction of the slit, the holder is not completely fixed and rattling occurs. Then, if the holder rattles in the circumferential direction, it looks cheap even if it does not hinder the function, and there is a possibility that it may cause abnormal noise.
[0007]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a mounting device for a panel hole which is prevented from rotating in the circumferential direction when mounted on the panel hole and can be firmly fixed.

As shown in FIG. 3A, the elastic locking piece 40 has a connecting portion 41 joined to the lower edge of the head 34 at a position coming out of the concave portion 33. Further, a tapered portion 42 protruding outward from the connecting portion 41 toward the base direction of the shaft portion 30, and a protruding piece portion 43 extending from the end of the tapered portion 42 in the base direction substantially parallel to the bottom surface of the base portion 22. And The inner side 44 of the elastic locking piece 40 extends substantially parallel to the opening of the column 33, and when viewed from the side, the elastic locking piece 40 has a triangular plate shape as a whole. In this embodiment, since the elastic locking piece 40 has a plate shape having a uniform thickness in the width direction, the inner side 44 forms the inner side of the thickest portion in the width direction.
[0028]
The elastic locking piece 40 is bendable with the connecting portion 41 as a fulcrum. When the elastic locking piece 40 is bent inward, the inner side 44 and the bottom side 45 are inserted into the recess 33. In this case, since the elastic locking piece 40 is formed at a position protruding from the opening of the concave portion 33 in a state of being molded as a whole, the inner width A of the concave portion 33 and the width B of the elastic locking piece 40 are set. Can be removed without forming a gap between them. That is, as long as the elastic locking piece 40 can be inserted into the concave portion 33, the width B can be made as close as possible to the internal method A, and the elastic locking piece 40 can be tightly inserted into the concave portion 33. Specifically, the ratio B / A of the width B of the elastic locking piece 40 to the inner dimension A of the recess 33 is preferably 0.9 to 1, and more preferably 0.95 to 0.99. preferable.
[0029]

Therefore, even if it is removed from the panel hole 11, there is a possibility that the elastic locking piece 40 does not completely return to the elastic state and a part of the inner side 44 remains in the concave portion 33. The fitting of such an embodiment is also included.
[0031]
Next, a method of using the attachment 20 will be described.
For example, the panel hole 11 is formed in advance on a panel 10 formed of a ceiling wall of an automobile or the like. Therefore, as shown in FIG. 4, the shaft portion 30 of the mounting tool 20 is inserted into the panel hole 11 from the head 34 side with the retaining portion 31 being aligned with the locking portion 12. As a result, the retaining portion 31 passes through the locking portion 12, the elastic locking piece 40 is pushed by the inner periphery of the panel hole 11 and inserted into the concave portion 33, and the shaft portion 30 protrudes from the back surface of the panel 10.

Further, the bottom surface of the base portion 22 contacts the panel 10.
[0032]
In this state, when the attachment 20 is rotated by approximately 90 degrees, the elastic locking piece 40 engages with the locking portion 12 of the panel hole 11, and the rotation is stopped at that position, as shown in FIG. . The retaining portion 31 engages with the opening edge of the panel hole 11 on the rear surface side of the panel 10 to prevent the shaft portion 30 from falling out of the panel hole 11. As a result, the fixture 20 is fixed to the panel 10.
[0033]
In this state, as shown in FIG. 5B, the elastic locking piece 40 is tightly inserted into the concave portion 33 so as to be in close contact with the inner wall of the pillar portion 32. For this reason, in the state where the elastic locking piece 40 is engaged with the locking portion 12, there is almost no play between the elastic locking piece 40 and the column 32, and the circumferential direction in a state where the mounting tool 20 is mounted is provided. Can be extremely reduced.
[0034]
If the gap D between the elastic locking piece 40 and the inner wall of the recess 33 is large as shown in FIG. Since it is possible to incline at a predetermined angle in the circumferential direction with respect to 30, rattling occurs between the two, and the mounting tool 20 rattles in the circumferential direction in the mounted state.
[0035]
If it is necessary to remove the attachment 20 after attaching the attachment 20 to the panel 10, insert a flathead screwdriver from the wider end 24 b of the groove 24, and remove the elastic locking piece 40. Forcibly pushing the shaft portion 30 into the concave portion 33, rotating the attachment 20 to align the retaining portion 31 with the locking portion 12, and pulling out the shaft portion 30 from the panel hole 11 in that state.
[0036]
FIG. 6 shows another embodiment of the fixture of the present invention. It is to be noted that the same reference numerals are given to substantially the same portions as those in the above-described embodiment, and description thereof will be omitted.
[0037]
In the attachment 20a of this embodiment, the distance between the inner side 44 of the elastic locking piece 40 and the opening of the recess 33 is 0, and the inner side 44 of the elastic locking piece 40 is Corner 44a and the corner 32a of the column 32 are connected.

When the fitting 20a is inserted into the panel hole 11 by the same operation as the above embodiment, the elastic locking piece 40 is pressed against the inner periphery of the panel hole 11, and the corner of the inner side 44 of the elastic locking piece 40 is formed. The burr connecting the portion 44a and the corner 32a of the column 32 is broken, and the elastic locking piece 40 is inserted into the recess 33. Therefore, in this embodiment, the inner dimension A of the concave portion 33 and the width B of the elastic locking piece 40 are substantially the same. The backlash in the circumferential direction of 10a can be more completely prevented.
[0039]
FIG. 7 shows still another embodiment of the fixture of the present invention.
The attachment 20b of this embodiment has a portion 46 that projects inward below the connecting portion 41 of the elastic locking piece 40. The protruding portion 46 is formed to be thinner than the thickness of the plate-like portion of the elastic locking piece 40 (the thickness of the thickest portion in the width direction), and has a sufficient clearance with the inner wall of the recess 33. Is inserted inside. Note that both side surfaces of the protruding portion 46 have a tapered shape extending toward the inner side 44 of the thickest portion, and function as a guide for guiding the elastic locking piece 40 into the recess 33.
[0040]
In the attachment 20b, since the inner side 44 of the thickest portion of the elastic locking piece 40 projects from the opening surface of the concave portion 33 with a space C, both side surfaces of the thickest portion of the elastic locking piece 40 are provided. There is no need to provide a gap for die release between the inner surface of the recess 33 and the width B of the thickest portion within the recess 33 as long as the elastic locking piece 40 can be inserted into the recess 33. It is possible to approach Law A. For this reason, the elastic locking piece 40 can be tightly inserted into the concave portion 33 to prevent rattling of the attachment 10a in the circumferential direction, and the elastic locking piece 40 can be guided by the protruding portion 46 so that the elastic locking piece 40 is 33 can be smoothly inserted.
[0041]
In the present invention, the elastic locking piece may be connected to the base of the shaft, and the tip of the shaft may be a free end.
[0042]
Further, the structure may be such that the elastic locking piece also serves as a retaining portion. For example, in the illustrated embodiment, a concave groove may be formed at the lower end of the tapered portion 42 of the elastic locking piece 40, and the peripheral edge of the panel hole 11 may be fitted into the concave groove so as to prevent the elastic hole 40 from coming off.
[0043]
Further, it goes without saying that various members other than the sun visor holder 21 can be applied as the attachment member.
[0044]
【The invention's effect】
As described above, according to the present invention, the thickest portion in the width direction of the elastic locking piece protrudes from the concave portion and is connected to the shaft portion at the position protruding from the concave portion so as to be bendable. There is no need to provide a gap for die release between the inner wall of the elastic locking piece and both sides of the elastic locking piece. The width can be made as close as possible, so that when the elastic locking piece is bent inward, the elastic locking piece is inserted into the recess in a tight state. In the state where the elastic engaging piece is engaged with the engaging portion of the edge, the elastic engaging piece hardly rattles in the concave portion, and the mounting member can be firmly fixed without rattling in the circumferential direction.
