なっている。The split ring 3 has a substantially 180-degree split structure. Also, the split ring 3 forms a flange portion 3a that protrudes radially outward from the annular convex portion 1a on the tube,
It is fitted and mounted in the annular concave portion 1b. That is, the first inner projection 3c is fitted in the annular concave portion 1b and mounted, and the protruding portion projecting radially outward from the annular convex portion 1a in the mounted state is a flange portion 3a on which the flange member 4 is hooked at the time of pipe connection. Becomes The flange member 4 has a through hole substantially at the center thereof and is loosely fitted to the outside of the blade 2 so as to be slidable in the tube axis direction. The flange 3a of the split ring 3 is engaged with the notch 4a in the tube axis direction at the time of connection, so that the front end face 3b of the split ring 3 is formed.
And the front end surface 4b of the flange member 4 are substantially flush.

凸部１ａの外側を覆うように後方側に延設されている。As described above, the split ring 3 has a flange 3a projecting radially outward from the annular projection 1a in the mounted state.
A cylindrical receiving portion 6 is provided on the rear side of the flange portion 3a so as to cover the bellows tube 1 over a predetermined length. The cylindrical receiving portion 6 has a diameter smaller than that of the flange portion 3a, and extends rearward so as to cover a plurality of annular convex portions 1a, specifically, two annular convex portions 1a.

ンジ部材４の内径よりも小径である。At the rear end of the receiving portion 6, a convex portion 7 protruding radially outward is formed over the entire circumference. However,
The protruding height is smaller than the flange portion 3a, and the convex portion 7 is smaller in diameter than the inner diameter of the flange member 4.

る。The receiving portion 6 is formed by the convex portion 7 and the flange portion 3a.
An annular concave portion having a predetermined width along the circumferential direction is formed on the outer peripheral surface of the optical disk. The blade 2 is externally fitted to the bellows tube 1 so as to cover the outer peripheral surface of the receiving portion 6 at the end 2a, and is fixed to the outer peripheral surface of the receiving portion 6 by crimping as follows.

ａよりも小径であって、接続時において図１のようにフ
ランジ部材４の内側に位置する構成である。That is, a fixing ring 5 is mounted on the outside of the end 2a of the blade 2, and the fixing ring 5 is caulked in the radial direction so as to reduce the diameter, so that the gap between the fixing ring 5 and the concave portion is reduced. The end 2a of the blade 2 is sandwiched and fixed between the two. The fixing ring 5 has a width smaller than the width of the concave portion and is caulked so as to engage with the concave portion. Therefore, the convex portion 7 formed at the rear end of the receiving portion 6 serves to prevent the blade 2 from coming off, and the fixing ring 5
Is prevented from coming off from the receiving portion 6 to the rear side. Further, the fixing ring 5 is formed to be thin,
It has a smaller diameter than a and is located inside the flange member 4 at the time of connection as shown in FIG.

て説明したが他端側についても同様の構成となってい
る。Further, on the inner peripheral surface of the receiving portion 6, a second inner projection 8 as a reinforcing rib protruding toward the center is formed over substantially the entire circumference along the circumferential direction. The amount of protrusion is appropriately determined by the material, thickness, and the like of the fixing ring 5. The second inner projection 8 is fitted in the annular recess 1b adjacent to the annular recess 1b in which the first inner projection 3c is fitted. In the above description, only one end of the tube has been described, but the other end has the same configuration.

ため、ブレード２を確実に固定することができる。ま
た、カシメにより固定する構成ゆえに、溶接に比して製
造も極めて簡易である。In the tube configured as described above, the receiving portion 6 is provided on the rear side of the flange portion 3a of the split ring 3, and the blade 2 is fixed to the receiving portion 6 by pressure bonding in the radial direction. Since no welding is required and there is no influence of heat, the blade 2 can be securely fixed. Further, since the structure is fixed by caulking, manufacture is extremely simple as compared with welding.
【００１９】更に、ブレード２の端部２ａが鍔部３ａよ

る。尚、シール部分に不要な出っ張りをなくすという点
についてはフランジ部材４の前端面４ｂと割リング３の
前端面３ｂとを略面一にしてことも無論寄与している。Further, since the end 2a of the blade 2 is located behind the flange 3a and does not protrude from the front end face of the split ring 3,
There is an advantage that the terminal treatment of the blade 2 is unnecessary and that there is no unnecessary protrusion at the seal portion (connection portion). It should be noted that, in terms of eliminating unnecessary protrusions in the seal portion, it is of course also possible to make the front end face 4b of the flange member 4 and the front end face 3b of the split ring 3 substantially flush.
【００２０】また、ブレード２の端部２ａを固定リング
５のカシメにより受け部６に圧着固定する構成である

め、カシメの際の径方向の力に対する強度を十分に確保
することが容易である。特に、凹部の幅方向（管軸方
向）略中央位置に第二内突起８を設けているため、効果
的に補強できる。The end 2a of the blade 2 is fixed to the receiving portion 6 by crimping of the fixing ring 5. However, since the second inner projection 8 is provided on the inner peripheral surface of the receiving portion 6, the caulking is performed. In this case, it is easy to sufficiently secure the strength against the radial force. In particular, since the second inner projection 8 is provided substantially at the center of the recess in the width direction (tube axis direction), it can be reinforced effectively.
【００２１】このように第二内突起８を設けたことによ

ｂに第二内突起８が嵌り込む構成であることからも全体
として受け部６を薄肉にできる。無論、比較的受け部６
を厚肉にできる等の場合には第二内突起８を設けない構
成とすることもできる。By providing the second inner projection 8 in this manner, the receiving portion 6 can be made thin as a whole, and the annular recess 1 can be formed.
The receiving portion 6 can be made thin as a whole because the second inner projection 8 is fitted into the b. Of course, relatively receiving part 6
In the case where the second inner projection 8 is not provided, for example, the thickness can be increased.
【００２２】一方、受け部６を後方側に延設しているの

（首元部）をこの受け部６で保護することができる。即
ち、接続部分から急激にチューブが曲がることが抑制さ
れるため、その部分における応力集中が緩和され損傷の
発生を抑制できるのである。On the other hand, since the receiving portion 6 extends rearward, the end portion (neck portion) of the tube, which is easily damaged by stress concentration, can be protected by the receiving portion 6. That is, since the tube is prevented from being sharply bent from the connection portion, the stress concentration in the portion is reduced, and the occurrence of damage can be suppressed.

Although the second inner projection 8 is fitted into the second annular projection 8, two or more of the second inner projections 8 may be fitted into the annular concave portion 1b on the rear side, or may be configured not to be fitted. Needless to say, a plurality of second inner projections 8 may be provided on the inner peripheral surface of the receiving portion 6 and may be fitted into the respective annular recesses 1b.

Can be fixed.
