ABSTRACT:
A clutch drum has a drum main body made of a metallic plate which is formed into a cup shape by drawing. Spline teeth for engaging with clutch plates are formed by pressing on a periphery of the drum main body. Pulsing teeth for detecting a rotational speed are formed by pressing on the periphery of the drum main body. An apparatus for manufacturing the clutch drum has a forming die onto which the drum main body is externally set in position. The forming die has formed thereon first tooth spaces corresponding to the spline teeth and second tooth spaces corresponding to the pulsing teeth. First tooth-shaped punches are provided so as to be movable radially back forth to form by pressing the spline teeth by urging the periphery of the drum main body into the first tooth spaces. Second tooth-shaped punches are provided so as to be movable also radially back and forth integrally with the first tooth-shaped punches to form by pressing the pulsing teeth by urging the periphery of the drum main body into the second tooth spaces.
