る。(Problem to be solved by the invention) However, the clutch drum cylindrical body which is drawn and formed using the above-described stepped punch has a small diameter part for storing the piston and a large diameter part for storing the clutch plate, and a small diameter part for storing the piston. Since the seal member attached to the piston slides, the punch part that forms it requires dimensional accuracy, while the large diameter part for storing the clutch plate requires a large amount of drawing, so it is difficult to form it. Parts must be durable.

硬度が低いので、耐久性に欠ける。 Therefore, if TiC with high hardness is used as the surface coating layer of such a punch, the hardness of the punch will increase and the durability will improve, but since the processing temperature is high, the punch is likely to be thermally deformed and the accuracy will be reduced. A problem arises. On the other hand, if TiN or W 2 C, which has a low processing temperature, is used to ensure accuracy,
Due to its low hardness, it lacks durability.
