以下、ｌ８ｌ而に不丁ー冥施例により本発明の詳細な説
明′ｖ６。Conventionally, when forming a recess V in the inner wall of a cylindrical body, the inner wall was formed by cutting, or the inner wall was pressed with a roller to form a bulge. However, Maname had the disadvantage that processing was time-consuming and it was not possible to efficiently mass-produce it. In addition, in the latter case, not only the inner wall but also the outer wall protrudes, so the outer wall has the disadvantage that it cannot be used for flat surfaces. In order to address the above-mentioned drawbacks of the conventional method, we have created a concave part on the inner wall that can make the outer periphery flat, reduce costs through efficient mass production, and allow small-diameter dimensions to be machined in two months. Hereinafter, the present invention will be described in detail with reference to some inconvenient examples.

Although we have explained the things that formed the
It is also possible to form a mountain-shaped recess on the inner wall by using a plurality of mountain-shaped protrusions formed on the outer periphery of the pan and teeth 10.
ａ上の説明から明らかなように本発明にあっては次に列
挙する効果がある。As is clear from the explanation above, the present invention has the following effects.
＜１）内壁に凹部ン形成した筒状体をダイスとパンチの
紋り加工によって成形することがで煮る。<1) A cylindrical body with a recess formed in the inner wall is formed by molding with a die and a punch.
したがって、効率良く多量体ｔＴることができる。Therefore, multimer tT can be produced efficiently.
（２）ダイスとパンチを用いて内壁に凹部Ｙ形成した筒
状体を成形できるので、筒状体の外崗壁は平坦にできる
。(2) Since a cylindrical body with a recess Y formed on the inner wall can be formed using a die and a punch, the outer wall of the cylindrical body can be made flat.
（３）紋り加工であるので、切削加工のように加工（二
手数がかからない。(3) Since it is a embossed process, it does not require two steps like cutting.
（４）夕°イスとパンチを用いた紋り加］’Ｔ艮いので
、筒状体の径か小径のものでも成形できる。(4) Forming using a chair and a punch] Since it is a T-shape, it is possible to form a cylindrical object with a diameter or a small diameter.
