本発明は、ボルト本体の軸部に座金な挿通保持して成る
座金付ボルトに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bolt with a washer that is inserted into and held in the shaft portion of a bolt body.
（従来の技術）
機械等の組立作業におけるボルト締めに際してその都度
ボルトに座金を挿通ずることは、特にボルト締付箇所か
多い場合には作業を著しく煩わしいものとする。(Prior Art) Inserting washers into bolts each time bolts are tightened in the assembly work of machines or the like makes the work extremely troublesome, especially when there are many bolts to be tightened.
そこて、座金を予めボルト本体の軸部に挿通保持して成
る座金付ボルトか使用される。Therefore, a bolt with a washer is used, in which a washer is inserted into and held in the shaft portion of the bolt body in advance.

。(Problem to be solved by the invention) However, in conventional bolts with washers, the washer can move freely between the head of the shaft and the threaded part, making assembly difficult and causing defects in the bolt body. There was a problem with the washer getting into the fully threaded part and damaging this part. In addition, especially when such a bolt is supplied by a parts feeder on an automatic assembly line, the parts feeder determines the direction of the bolt by measuring the weight of the bolt and determines whether it is on the heavy side or the head. If the washer can move freely on the shaft, this judgment may be incorrect. In addition, as a method of regulating the movement of the washer, a protrusion is formed near the base of the shaft of the bolt body, and the washer is press-fitted through the protrusion and is rotatably held on the shaft. This method has already been proposed (see Japanese Utility Model Publication No. 48-20821), but this method requires machining of the inner peripheral portion of the washer and also requires work to press-fit the washer into the protrusion.

きる座金付ボルトを提供するにある。The present invention has been made in view of the above problems, and its purpose is to reliably restrict the free movement of the washer by applying simple processing to the shaft portion of the bolt body. To provide a bolt with a washer that improves assembly efficiency and prevents damage to incompletely threaded parts.

特徴とする。(Means for Solving the Problems) In order to achieve the above object, the present invention has a threaded part formed by rolling at the end of the shaft 1 part of the bolt body, and the threaded part of the coaxial part and the head part of the bolt body have a threaded part formed by rolling. In a bolt with a washer that is formed by inserting and retaining a washer between the parts, a stopper is integrally formed by rolling at a position on the head side of the center of gravity of the bolt body of the shaft part, and the stopper and the head part are integrally formed. The washer is arranged between.

Therefore, it is possible to obtain the bolt with the washer without requiring an extra number of bolts, and it is also possible to reliably restrict the free movement of the washer, thereby preventing damage to the incompletely threaded part of the bolt. You can prevent 1t. By using the washer I, the ease of assembly can be improved.

向の判断に狂いか生ｌノることかない。In addition, in the case of the washer bolt, the washer is located closer to the head than the center of gravity of the bolt body, so the weight on the head side is always larger, which may cause errors in determining the direction of the bolt in the parts feeder. That's not true.
（実施例）
以下に本発明の一実施例を添付図面に基づいて説明する
。(Example) An example of the present invention will be described below based on the accompanying drawings.

か転造によって刻設されている。The drawing is a cross-sectional view showing the bolt with washer 1 according to the present invention, and the main body of the bolt with washer 1-1 includes a hexagonal column-shaped head 2 and an extension from the head 2 to the body. Round bar-shaped shaft part 3
The shaft portion 3 has a threaded portion 4 extending a predetermined length from the end thereof.
It is engraved by rolling.

の落下は該ストッパ５によって阻止される。In addition, in the vicinity of the head 2 of this shaft portion 3, specifically, at a position closer to the head 2 than the center of gravity G of the main body of the bolt 1 (the center of gravity of the bolt main body excluding the washer 6, which will be described later), there is a 1 The stopper 5, which is constituted by a threaded thread, is integrally formed by rolling. A washer 6 is inserted between the head 2 of the shaft 3 and the stopper 5, and the inner diameter d of the washer 6 is larger than the outer diameter D1 of the shaft 3, and the stopper 5 (Dl<d<D2
). Therefore, although the washer 6 can freely move between the head 2 of the shaft portion 3 and the stopper 5, the stopper 5 prevents the washer 6 from falling downward from the stopper 5.

ことなく容易に形成される。In actual manufacturing, the washer 6 is inserted into the shaft portion 3 before the threaded portion 4 and the stopper 5 are formed on the shaft portion 3.
Next, the stopper 5 and the threaded portion 4 are formed by rolling. In this way, since the stopper 5 is additionally formed in the process of forming the threaded portion 4, it can be easily formed without requiring almost any extra processing steps.

その本来の機能を果たす。In order to fasten the illustrated member A to the member B using the washer bolt 1, the shaft portion 3 of the bolt 1 is inserted into the hole 11 drilled in the member A, and the shaft portion The threaded portion 4 formed at the tip of the member B is screwed into the screw hole 12 formed in the member B, and a tool such as a spanner is engaged with the head 2 to turn it. Then, the member A is attached to the hole 1 as shown in the figure.
The washer 6 is firmly fastened to the member B, and at this time the washer 6 is interposed between the head 2 of the bolt main body and the member A and performs its original function.

く高めることかてきる。In the above, the movement of the washer 6 on the shaft portion 3 is controlled by the stopper 5.
This eliminates the problem of the washer 6 getting into the incompletely threaded portion a of the shaft portion 3 and damaging this portion a. By using the bolt with washer 1, the work can be carried out efficiently and the ease of assembly can be significantly improved.

ボルト１は常に正しい方向て供給される。In addition, in the holt 1 with a washer, as described above, the washer 6 is located closer to the head 2 than the center of gravity G of the main body of the holt 1, so the weight on the M part 2 side with respect to the center of gravity G is always large, so that the parts feeder will not be able to judge the direction of the bolt 1 incorrectly,
The bolt 1 is always fed in the correct direction.
