Description of the Related Art Conventionally, in order to join opposite ends of a set of members to be joined by using this kind of friction joining method, first, as shown in FIG. After the opposing ends of the joined members a and b are brought into contact with each other, the one joined member a is rotated and pressed toward the other joined member b in a fixed state. At this time, the members to be joined a,
b, frictional heat is generated on the contact end surface, and the contact end surface is melted by the frictional heat, so that the position S 1 of the contact end surface becomes a predetermined amount t.
And 1 move displaced S 2 (see Figure 5 (b)). Then, the movement amount t 1 at this time becomes the initial displacement amount.

Is moved by a predetermined amount t 2 (see FIG. 5C), whereby the sum of the movement amount t 2 and the initial displacement amount t 1 becomes the total displacement amount t, and , B are joined at opposite ends. Here, the total replacement amount t is fixed,
This controls the accuracy of the lengths of the joined members a and b.

For this reason, when the members a to be joined are pressed toward the members b to be joined, the members a and b
May not be displaced until the value is obtained. That is, the amount plus the amount of movement t 2 and the initial Yadorikidai amount t 1 does not reach the total Yadorikidai amount t. As a result, it becomes impossible to obtain an accurate total displacement amount t, and the joined members a and b are joined.
However, there is a disadvantage that the accuracy of the length is reduced.

In addition, there is an inconvenience that the members a and b are deformed by distortion.
