[0003] This kind of piercing is generally formed by forming the pair of members 100, 100 by cast molding called casting. Here, assembling one of the pair of members 100, 100 in a rotating state with the other is generally the most commonly performed by forming a narrow insertion portion 101 at one end of one of the members 100. At the other end, a pair of bearing portions 102, 102 for receiving the insertion portion 101 so as to be sandwiched from both sides is formed.
A shaft pin 104 is inserted into a shaft hole 103 provided so as to communicate with the pair of bearing portions 102, 102 and the insertion portion 101.
It is done by inserting. (FIG. 7)

[0004]

However, when the pair of members 100, 100 are integrally formed with the bearing portion 102 and the insertion portion 101 by the casting,
It is difficult to ensure high dimensional accuracy of the bearing portion 102 and the insertion portion 101, and it is not uncommon to need to separately perform processing such as extraordinary surface polishing or the like before combining the two without looseness. .

If the pair of members 100, 100 are formed by press working, the member 1
00 can be made thinner than in the case of casting, the weight of the piercing can be reduced, and the piercing constituent material can be effectively used. In this way, while forming the pair of members 100, 100 by pressing, the pair of members 100, It is difficult to provide the bearing portion 102 and the insertion portion 101 integrally with the bearing 100, so that this type of piercing is difficult to form by press working. Further, the pair of members 100, 1
In the method of assembling 00 in a rotatable manner, the pair of members 100 cannot be shared as components.

In view of the above, the present invention provides a ring-shaped piercing device which includes a pair of ring members rotatably assembled at one end thereof, and the other ends of which are engaged with each other. It is a main object to enable a pair of ring members to be easily and appropriately rotatably assembled.

(1) A pair of ring members that are rotatably mounted on one end side and are rotated so that the other end portions are engaged with each other around the rotation mounting portion to form an annular body. (2) The pair of ring members each form a bottom plate portion forming an outer peripheral surface of the ring member, and along both side edges of the bottom plate portion, from the side edge toward the inside of the ring member. A protruding rising plate portion, the cross-sectional shape of which on the side facing the inside of the annular body is formed to have a U-shape that is open at the side facing the inside of the annular body; However, one end of the connection member inserted into the pair of ring members over the end of the pair of ring members on the rotational assembly side is brazed to one of the pair of ring members by brazing or the like. It is fixed, and the other end of the connection member is a pair of ring structures. The other is formed by inserting a shaft pin into a shaft hole provided in communication with both rising plate portions of the other ring constituting body and the other end portion of the connecting member, thereby fixing the shaft. .

According to this structure, the pair of ring members provided so as to have a U-shaped cross-section in the width direction extends between the ends of the pair of ring members on the rotational assembly side. By assembling the connecting member, the pair of ring members can be easily and appropriately rotatably assembled.

In particular, since it is not necessary to form the pair of ring members themselves into a shape such that the other rotation member is inserted inside one of the rotation members, the ring members are press-formed. Thus, the configuration can be made without any trouble, and the pair of ring components can be used as common parts.

[0010] Further, since such a ring structure has both rising plate portions having a U-shaped cross section along the width direction,
Both ends of the shaft pin passed through the shaft hole of the connection member can be stably supported by the shaft holes provided in the both rising plate portions.
