題もある。However, as in the prior art, when the screw portion 7c interferes with the metal skin 1 during the drilling of the base material 8 by the drill portion 7d, the screw portion 7c has the metal skin 1 In this case, the cutting speed at the tip of the drill portion 7d and the feed speed by the screw portion 7c are different from each other, the screw portion 7c and the metal skin 1 are locked, and the drill portion 7d does not rotate. The tightening hole of the drill screw head 6 may be crushed. In particular, when a tool having a high tightening torque such as a screwdriver is used, the tightening hole of the drill screw head 6 is damaged and the drill screw 5'cannot be tightened, resulting in a large loss and a poor yield. There is.
If a tool with a weak torque is used to prevent the tightening holes of the drill screw head 6 from collapsing, the drill portion 7
There is a problem that the base material 8 cannot be perforated by d and the drill screw 5'cannot be tightened. Also,
As in the conventional case, the outer diameter L 3 of the drill screw foot portion 7 is equal to the screw portion 7
When the outer diameter L 4 of c is set to be the same as or smaller than the outer diameter L 4 , the drill screw 5'is set at the end of tightening of the base material 8 by the screw portion 7c as shown in FIG. 8 (a). It is unavoidable that the screw is tightened too much, and it becomes difficult to stop the screw portion 7c at an appropriate position in the base material 8. Moreover, since the backing material 3 lined with the metal outer cover 1 is made of a material having low strength such as urethane foam, if the drill screw 5'is over-tightened, the portion of the metal outer cover 1 in contact with the drill screw head 6 is compressed. As a result, there is also a problem that a recess is generated in the metal outer cover 1 and the appearance of the panel 4'is impaired.

The packing 9 is externally fitted, and in this state, the drill portion 7d at the tip of the drill screw 5 is driven from the side of the metal skin 1 toward the panel 4 and the base material 8. In the case where the drill portion 7d perforates the base material 8, the screw portion 7c is located outside the panel 4 and does not interfere with the metal skin 1 as shown in FIG. As described above, the screw portion 7c does not lift the metal outer cover 1. Therefore, there is no difference between the cutting speed at the tip of the drill portion 7d and the feed speed by the screw portion 7c, and it is possible to prevent the screw portion 7c and the metal skin 1 from being locked. This allows
The drill portion 7d can rotate smoothly, and there is no concern that the tightening hole 6a of the drill screw head 6 will be crushed.

を奏する。As described above, according to the first aspect of the present invention, there is provided a drill screw for fixing a panel having a backing material provided on the back side of the metal outer cover to a base material, the drill screw including a foot portion of the drill screw. A screw part to be screwed into the perforated part of the base material and a drill part for perforation are sequentially formed at a predetermined distance from the base end, and the screw part is a metal outer shell when the base part is perforated by the drill part. It is formed in a position that does not interfere with
Since the stopper portion that abuts the peripheral portion of the hole portion of the base material is projected at one end on the side opposite to the drill portion of the screw portion, the screw portion is a metal skin while the base material is being drilled by the drill portion. No longer interfere with. Therefore, unlike the conventional case, the screw part does not lift up the metal skin, so that there is no difference between the cutting speed of the tip of the drill part and the feed speed by the screw part, and the screw part and the metal skin are locked. It can be avoided. This allows the drill to rotate smoothly,
No more worrying about crushing the tightening holes on the drill screw head,
As a result, the loss is small and the yield is improved. Further, by providing a stopper portion that abuts the peripheral portion of the hole edge of the perforated portion of the base material at one end on the side opposite to the drill portion of the screw portion,
At the end of tightening the base material by the screw portion, the stopper portion comes into contact with the peripheral portion of the hole edge to prevent the screw portion from screwing, so that the screw portion can be stopped at an appropriate position in the base material. Like Therefore, since it is possible to prevent the occurrence of the depression of the metal skin due to the excessive tightening of the drill screw, it is possible to maintain the good appearance of the panel.
