−Ｘ軸上にある。 The first frame 6 includes two parts provided on the pedestal 4 as described below.
It can swing freely within the opening 5 by means of the hanging tools 8, and has a square opening 7 in its center. The hanging tool 8 has a structure in which a universal hanging shaft 10 is attached to a bracket 9 provided on the pedestal 4, and a spherical bearing 11 at the tip thereof is attached to the first frame 6 so as to be swingable. Further, the mounting position of the opposing spherical bearings 11 is on the side of the first frame 6 and is perpendicular to the line of action of the center of gravity of the first frame 6.
- is on the X axis.
したがつて、第１枠体６は、前記Ｘ−Ｘ軸と直
交する軸線が上下に傾斜し、架台４がこれにつれ

１９の取付位置は、第２枠体１２の上方であつ
て、第２枠体１２の重心の作用線と直交するＹ−
Ｙ軸上にある。 The second frame 12 is made of a rectangular tube having a square opening 13 in the center through which the rod-shaped body 1 is inserted.
The opposing inner surface has a head section 1 which can be operated externally.
A measuring tool 14 and a guide roller 16 are provided. And this second
The frame 12 is attached to its upper surface by a hanging tool 17 having substantially the same structure as the hanging tool 8, so as to be swingable about the Y-Y axis. And the hanging tool 1
The mounting position of the spherical bearing 19 at the tip of the universal hanging shaft 18 attached to the shaft 7 is above the second frame 12 and is in the Y-direction perpendicular to the line of action of the center of gravity of the second frame 12
It is on the Y axis.
したがつて、第２枠体１２は前記Ｘ−Ｘ軸が上
下に傾斜しても前述の第１枠体６と同様水平状態
を保持する。 Therefore, the second frame 12 maintains a horizontal state like the first frame 6 described above even if the X-X axis is tilted up or down.
つまり、第２枠体１２は架台４がいずれの方向
に傾斜していても、常に水平状態を保持すること
になる。 In other words, the second frame 12 always maintains a horizontal state even if the pedestal 4 is tilted in any direction.

上に載置する。この場合、架台４が、仮に水平状
態に載置されていなくても、前記理由により第２
枠体１２は常に水平状態を保持する。 In order to measure the outer diameter dimension of the rod-shaped body 1 with the measuring device having the above-mentioned configuration, the pedestal 4 is placed between two supports 2.
Place it on top. In this case, even if the pedestal 4 is not placed horizontally, the second
The frame body 12 always maintains a horizontal state.
