できるようなアタツチメントの連結機構が必要と
なる。 Generally, the main body arm of a civil engineering machine, to which an attachment such as a bucket belt is removably attached, has slightly different widths and pin hole diameters depending on the manufacturer. For this reason, when connecting stays of the same attachment to arms of different models, there have been problems such as the stay not being able to be attached or damage to members due to mismatching of the connecting portions. In particular, in recent years, when the same attachment is rented to users of different types of civil engineering machine bodies, there is a need for an attachment connection mechanism that can be commonly adapted to the main body arm of any manufacturer.

ツシユを用意しておかなければならない。 However, when using a bush in which the large diameter part is integrally formed with fixed dimensions as in the above-mentioned known example, each time the inner width between the stays and the width of the arm differ,
A bush having a large diameter portion with a length corresponding to the gap is required, and therefore many types of bushes must be prepared in advance.

ム１のピン孔１′に嵌入して連結する。 FIGS. 3 and 4 show an embodiment in which when the pin hole 7' of the stay 7 is larger than the pin hole 1' of the arm 1, it is connected with a pin 3 that fits the pin hole 1' of the arm. In this case, the cylindrical portion 8a of the boss 8 is fitted into the pin hole 7' of the stay 7. On the other hand, if the pin hole 1' of the arm 1 is larger than the pin hole 7' of the stay 7, the cylindrical part 8a of the boss 8 is inserted into the pin hole 1' of the arm 1 and connected as shown in FIG. .
