The parts corresponding to those in FIGS. 3A, 3B and 4 described above are designated by the same reference numerals.
【００１７】 タッピングねじ２を捩じ込む対象物である捩じ込み対象部材３に設けられてい る本例のタッピングねじ用下孔１は、図示のように、該タッピングねじ２のねじ 部の直径より小さい内径で設けられている下孔本体部１ａと、該下孔本体部１ａ の入口に該タッピングねじ２のねじ部２ａを差し込める内径で連設されているね じ差込み孔部１ｃと、捩じ込み対象部材３の表面に開口させてねじ差込み孔部１ ｃの入口に設けられたテーパ孔部１ｂとで構成されている。この場合、ねじ差込 み孔部１ｃの内径は、タッピングねじ２の差し込みがスムーズに行え且つ該ねじ 差込み孔部１ｃ内でタッピングねじ２の倒れが行われないように、（タッピング ねじ２のねじ部２ａの直径＋α）に設定されている。αとしては、タッピングね じ２のねじ部２ａの直径の大きさにもよるが、例えば0.1 〜0.2mm 程度の値を設 定する。As shown in the figure, the tapping screw pilot hole 1 provided in the screwing target member 3 that is the target to which the tapping screw 2 is screwed in has a diameter of the threaded portion of the tapping screw 2. A pilot hole body portion 1a having a smaller inner diameter, and a screw insertion hole portion 1c continuously provided with an inner diameter that allows the screw portion 2a of the tapping screw 2 to be inserted into the inlet of the pilot hole body portion 1a. It is configured with a taper hole portion 1b which is opened on the surface of the screw-in target member 3 and provided at the entrance of the screw insertion hole portion 1c. In this case, the inner diameter of the screw insertion hole 1c is set so that the tapping screw 2 can be inserted smoothly and the tapping screw 2 does not fall inside the screw insertion hole 1c (the screw of the tapping screw 2 is It is set to the diameter of the portion 2a + α). Although α depends on the size of the diameter of the threaded portion 2a of the tapping screw 2, it is set to a value of, for example, about 0.1 to 0.2 mm.
【００１８】 図２に示すように、一方の構成部材である捩じ込み対象部材３に他方の板状構 成部材４を重ね、タッピングねじ２でこれらを連結するに際しては、板状構成部 材４のねじ通し孔５を下孔１に合致させ、ねじ通し孔５からタッピングねじ２を 通して該タッピングねじ２をテーパ孔部１ｂを経てねじ差込み孔部１ｃに差し込 む。この状態でタッピングねじ２は、倒れないようにねじ差込み孔部１ｃに保持 されている。かかる状態で、タッピングねじ２を下孔本体部１ａに捩じ込む。こ のときタッピングねじ２は、ねじ差込み孔部１ｃでその軸心方向に軸心が向いた 状態に保持されているので、倒れを防止して下孔本体部１ａに捩じ込むことがで きる。As shown in FIG. 2, when the member 3 to be screwed in, which is one of the constituent members, is overlapped with the other plate-shaped constituent member 4 and they are connected by the tapping screw 2, the plate-shaped constituent member is used. The threaded hole 5 of 4 is aligned with the lower hole 1, the tapping screw 2 is passed through the threaded hole 5, and the tapping screw 2 is inserted into the screw insertion hole 1c through the tapered hole 1b. In this state, the tapping screw 2 is held in the screw insertion hole 1c so as not to fall. In this state, the tapping screw 2 is screwed into the pilot hole body 1a. At this time, the tapping screw 2 is held in the screw insertion hole 1c with its axis oriented in the axial direction, so that it can be prevented from falling and can be screwed into the pilot hole body 1a. .

本考案に係るタッピングねじ用下孔は、下孔本体部の入口に、タッピングねじ のねじ部を差し込める内径でねじ差込み孔部を連設しているので、該タッピング ねじを該捩じ込み対象部材に捩じ込むに際しては、該タッピングねじをまず該ね じ差込み孔部に差し込むことができる。このためタッピングねじは、該ねじ差込 み孔部でその軸心方向に軸心が向いた状態に保持され、かかる状態で下孔本体部 に捩じ込まれるので、倒れを防止して捩じ込むことができる。 In the tapping screw pilot hole according to the present invention, the tapping screw is the object to be screwed in because the tapping screw has an inner diameter that allows the threaded portion of the tapping screw to be inserted at the entrance of the pilot hole main body. When screwing into the member, the tapping screw can first be inserted into the screw insertion hole. For this reason, the tapping screw is held in the screw insertion hole with its axis oriented in the axial direction, and is screwed into the pilot hole main body in such a state, preventing it from falling and twisting. Can be crowded.
【００２１】 特に、タッピングねじの捩じ込み開始時の倒れ防止を、このように下孔の形状 により対拠すると、タッピングねじ自身の先端に、下孔本体に差込める直径のね じなし部を設けた特殊なタッピングねじを用いて対拠する対拠の仕方に比べて、 ユーザー側が普通のタッピングねじを用いて容易に対拠できる利点がある。[0021] In particular, if the tapping screw is prevented from falling at the start of screwing in such a manner that the shape of the pilot hole is used as a countermeasure, a tip of the tapping screw itself has a screwless portion having a diameter that can be inserted into the pilot hole body. Compared to the method of using the special tapping screw provided, the user has the advantage that he or she can easily use the ordinary tapping screw.
【００２２】 また、ねじ差込み孔部があると、タッピングねじを倒れさせずに保持させるこ とができるので、捩じ込み初めに下孔本体部からタッピングねじが脱落すること がなくなり、能率よくタッピングねじの捩じ込みを行うことができる。In addition, if there is a screw insertion hole, the tapping screw can be held without falling down, so that the tapping screw will not fall off from the pilot hole main body at the beginning of screwing, and the tapping screw can be efficiently tapped. The screw can be screwed in.
【００２３】 この場合、ねじ差込み孔部の入口にテーパ孔部を設けておくと、該テーパ孔部 によるガイド作用によりタッピングねじをねじ差込み孔部に容易に差し込むこと ができる。In this case, if a taper hole portion is provided at the inlet of the screw insertion hole portion, the tapping screw can be easily inserted into the screw insertion hole portion due to the guide action of the taper hole portion.

本考案に係るタッピングねじ用下孔を設けた捩じ込み対象部材は、下孔本体部 の入口に、タッピングねじのねじ部を差し込める内径でねじ差込み孔部を連設し ているので、該タッピングねじを該捩じ込み対象部材に捩じ込むに際しては、該 タッピングねじをまず該ねじ差込み孔部に差し込むことができる。このためタッ ピングねじは、該ねじ差込み孔部でその軸心方向に軸心が向いた状態に保持され 、かかる状態で下孔本体部に捩じ込まれるので、倒れを防止して捩じ込むことが できる。The screwing target member provided with the tapping screw pilot hole according to the present invention has the screw insertion hole portion continuously connected to the inlet of the pilot hole main body with an inner diameter into which the screw portion of the tapping screw can be inserted. When screwing the tapping screw into the screw target member, the tapping screw can be first inserted into the screw insertion hole. Therefore, the tapping screw is held in the screw insertion hole with its axis oriented in the axial direction, and is screwed into the pilot hole main body in such a state, so that the tapping screw is prevented from falling and is screwed in. be able to.
【００２１】 特に、タッピングねじの捩じ込み開始時の倒れ防止を、このように下孔の形状 により対拠すると、タッピングねじ自身の先端に、下孔本体に差込める直径のね じなし部を設けた特殊なタッピングねじを用いて対拠する対拠の仕方に比べて、 ユーザー側が普通のタッピングねじを用いて容易に対拠できる利点がある。[0021] In particular, if the tapping screw is prevented from falling at the start of screwing in such a manner that the shape of the pilot hole is used as a countermeasure, a tip of the tapping screw itself has a screwless portion having a diameter that can be inserted into the pilot hole body. Compared to the method of using the special tapping screw provided, the user has the advantage that he or she can easily use the ordinary tapping screw.
【００２２】 また、ねじ差込み孔部があると、タッピングねじを倒れさせずに保持させるこ とができるので、捩じ込み初めに下孔本体部からタッピングねじが脱落すること がなくなり、能率よくタッピングねじの捩じ込みを行うことができる。In addition, if there is a screw insertion hole, the tapping screw can be held without falling down, so that the tapping screw will not fall off from the pilot hole main body at the beginning of screwing, and the tapping screw can be efficiently tapped. The screw can be screwed in.
【００２３】 この場合、ねじ差込み孔部の入口にテーパ孔部を設けておくと、該テーパ孔部 によるガイド作用によりタッピングねじをねじ差込み孔部に容易に差し込むこと ができる。In this case, if a taper hole portion is provided at the inlet of the screw insertion hole portion, the tapping screw can be easily inserted into the screw insertion hole portion due to the guide action of the taper hole portion.
