To this end, the present invention provides a sheet metal nut as described above, in which a claw piece is formed on the annular flange portion to protrude in the screwing direction of the sheet metal nut and toward the tightening seat surface, thereby preventing excessive tightening torque of the sheet metal nut. At times, the claw pieces bite into the tightening seat surface.
以下、本考案の実施例を図面に基づいて説明す

説明を省略するものとする。 Here, in the same or corresponding parts as the conventional sheet metal nut shown in FIGS. 4 and 6, there is a fourth
Explanation will be omitted by assigning the same reference numerals as those in the figure and FIG. 6.
この実施例は、第１図ないし第３図に示される
ように、板金ナツトＮの環状鍔部１２に、板金ナ

よび第２図において時計回り方向に突出されてい
る。 The claw piece 17 protrudes toward the tightening seat side 15, that is, toward the bottom in FIG.
In FIGS. 2 and 3, the tip of the claw piece 17 protrudes to the left side of the figure, and the tip of the claw piece 17 is directed in the screwing rotation direction 16 of the sheet metal nut N, that is, in the clockwise direction in FIGS. 1 and 2. It is prominent.
前記板金ナツトＮは、例えば、インパクトレン
チ等により合成樹脂製のボス３の外周面をねじ立
てしつつ時計回り方向にねじ込まれる。 The sheet metal nut N is screwed in clockwise while screwing the outer peripheral surface of the boss 3 made of synthetic resin using, for example, an impact wrench or the like.

付けを止める。 The tip of the claw piece 17 of the annular flange 12 of the sheet metal nut N screwed into the boss 3 comes into contact with the lower back panel 2 of the tightening seat surface, and when excessive tightening torque is applied to the sheet metal nut N, the claw piece 17 The tip of the lower back panel 2 bites into the surface of the lower back panel 2, and functions to rapidly increase the frictional resistance between the nut and the lower back panel 2, thereby stopping the tightening of the sheet metal nut N.
その結果、板金ナツトＮのねじ立て部１３によ

る。 As a result, before the male screw 5 tapped into the outer circumferential surface of the boss 3 by the tapped portion 13 of the sheet metal nut N is cut off due to excessive tightening torque, the impact wrench is screwed into the sheet metal nut N and is in operation. The set torque (impact wrench stop torque) can be reached reliably.
従つて、ボス３の外周面にねじ立てされた雄ね
じ５が板金ナツトＮのねじ立て部１３によりねじ
切られて不完全ねじ部６となることはなくなる。 Therefore, the male thread 5 tapped on the outer circumferential surface of the boss 3 will not be threaded off by the tapped portion 13 of the sheet metal nut N and become an incompletely threaded portion 6.
第３図は、ボス３の外周面を正常にねじ立てし
てねじ込まれた板金ナツトＮとそのボス３との螺
合関係を示したものである。 FIG. 3 shows the screwing relationship between the boss 3 and the sheet metal nut N, which has been screwed in by properly tapping the outer peripheral surface of the boss 3.
