The tip retaining member (3) is a short round bar having an outer diameter substantially the same as the outer diameter of the pin body (2). The front end of the tip retaining member (3) is smoothly inserted into the pin insertion holes (A11), (A21), and (B11) of machine parts (A) and (B) (see FIG. 3). The peripheral portion is chamfered obliquely to be tapered.
The distal end retaining member (3) is formed with a slit portion (31) cut from the rear end surface (base end surface) toward the front (front end side). The slit portion (31) is formed so as to pass through the central axis of the tip retaining member (3) and is opened on both the upper and lower sides of the tip retaining member (3).

次に、上記トグルピン(1)を使用して２つの機械部品（対象物品）(A)(B)を相対回動可能に連結する手順を、図３を参照しながら説明する。
まず、一方の連結対象物品である第１の機械部品(A)は、互いに所定間隔をおいて配された左右１対の連結端部(A1)(A2)を有している。各連結端部(A1)(A2)には、前後方向にのびるピン挿通孔(A11)(A21)が形成されている。
また、他方の連結対象物品である第２の機械部品(B)は、第１の機械部品(A)の２つの連結端部(A1)(A2)どうしの間に介在される１つの連結端部(B1)を有している。連結端部(B1)には、前後方向にのびるピン挿通孔(B11)が形成されている。
Next, a procedure for connecting the two mechanical parts (target articles) (A) and (B) so as to be relatively rotatable using the toggle pin (1) will be described with reference to FIG.
First, the first mechanical component (A), which is one of the articles to be connected, has a pair of left and right connecting ends (A1) (A2) arranged at a predetermined interval from each other. Each connecting end (A1) (A2) is formed with pin insertion holes (A11) (A21) extending in the front-rear direction.
Further, the second machine part (B) which is the other object to be connected is one connection end interposed between the two connection ends (A1) (A2) of the first machine part (A). Part (B1). A pin insertion hole (B11) extending in the front-rear direction is formed in the connection end (B1).
両機械部品(A)(B)の連結に際しては、それぞれの連結端部(A1)(A2),(B1)のピン挿通孔(A11)(A21),(B11)が直列状に並ぶように、例えば両機械部品(A)(B)を作業者が片方の手で保持しておく。
トグルピン(1)は、図３（ａ）に示すように、ピン本体(2)の嵌合凹部(22)と先端抜け止め部材(3)の嵌合凸部(32)とが嵌め合わせられて、ピン本体(2)および先端抜け止め部材(3)が直列状に配された状態としておく。
そして、例えば作業者が他方の手でトグルピン(1)を持って、先端抜け止め部材(3)の方から、両機械部品(A)(B)の連結端部(A1)(A2),(B1)のピン挿通孔(A11)(A21),(B11)に順次挿通させていく。この際、例えばトグルピン(1)が回転したとしても、嵌合凹部(22)と嵌合凸部(32)とが嵌め合わせられているため、自重等により先端抜け止め部材(3)が不用意に折れ曲がることがなく、ピン挿通孔(A11)(A21),(B11)にスムーズに挿通させることが可能である。
When connecting both machine parts (A) and (B), make sure that the pin insertion holes (A11), (A21), and (B11) of each connection end (A1) (A2), (B1) are aligned in series. For example, the operator holds both machine parts (A) and (B) with one hand.
As shown in FIG. 3A, the toggle pin (1) is formed by fitting the fitting concave portion (22) of the pin body (2) and the fitting convex portion (32) of the tip retaining member (3). The pin body (2) and the tip retaining member (3) are arranged in series.
And, for example, the operator holds the toggle pin (1) with the other hand, and from the tip retaining member (3), the connecting ends (A1) (A2), ( B1) are sequentially inserted through the pin insertion holes (A11), (A21), and (B11). At this time, for example, even if the toggle pin (1) rotates, the fitting recess (22) and the fitting projection (32) are fitted together, so the tip retaining member (3) is not prepared due to its own weight or the like. The pin can be smoothly inserted into the pin insertion holes (A11), (A21), and (B11) without bending.
図３（ｂ）に示すように、トグルピン(1)を全てのピン挿通孔(A11)(A21),(B11)に挿通させて、先端抜け止め部材(3)が第１の機械部品(A)の前側連結端部(A2)の前方に飛び出した時点で、先端抜け止め部材(3)を前方に引っ張ると、嵌合凸部(32)が嵌合凹部(22)から外れる。 As shown in FIG. 3 (b), the toggle pin (1) is inserted through all the pin insertion holes (A11), (A21), (B11), and the tip retaining member (3) is attached to the first machine part (A When the front-end retaining member (3) is pulled forward when the front connection end (A2) protrudes forward, the fitting protrusion (32) comes off the fitting recess (22).
この状態から、図３（ｃ）に示すように、先端抜け止め部材(3)を折り曲げると、それによって先端抜け止め部(30)が形成される。
以上の工程により、第１の機械部品(A)の連結端部(A1)(A2)と、第２の機械部品(B)の連結端部(B1)とが、トグルピン(1)によって相対回動可能に連結される。
また、トグルピン(1)は、折り曲げた状態の先端抜け止め部材(3)よりなる先端抜け止め部(30)と、ピン本体(2)の基端抜け止め部(23)とによって、連結端部(A1)(A2),(B1)のピン挿通孔(A11)(A21),(B11)から抜け落ちないようになっている。
したがって、この実施形態のトグルピン(1)によれば、容易にかつ迅速に挿通作業を行うことができる。
なお、図示は省略したが、第１の機械部品(A)の連結端部(A1)(A2)と、第２の機械部品(B)の連結端部(B1)との連結を解除して分解する場合には、上記と逆の操作を行えばよく、その際にも、トグルピン(1)をピン挿通孔(A11)(A21),(B11)から引き抜く作業を容易にかつ迅速に行うことが可能である。
From this state, as shown in FIG. 3C, when the tip retaining member (3) is bent, the tip retaining portion (30) is formed.
