Abstract
PURPOSE: To enable formation of high accuracy for a clutch drum appropriate to the automatic transmission of an automobile or the like, by providing drawing recesses on the inside and outside of the almost cylindrical clutch plate engagement portion of the clutch drum so that the tips of inner and outer spline teeth are opposed to the drawing recesses.
CONSTITUTION: Outer spline teeth 3, which are engaged with the first clutch plate of large diameter, are provided by press formation on the outside of the almost cylindrical clutch plate engagment portion 2 of a clutch drum 1 for an automatic transmission. Inner spline teeth 4, which are engaged with the second clutch plate of small diameter, are provided by press formation on the inside of the engagement portion 2. Wave-shaped drawing recesses 5 for letting drawn parts go during the press formation are provided between the tips 4a 3a of the inner and the outer spline teeth 4, 3. Therefore, the material of the clutch drum 1 deformed at the inner and the outer spline teeth 4, 3 during the press formation of the clutch drum 1 can go into the drawing recesses 5. This results in enhancing the accuracy of press working of the spline teeth 4, 3.
