    • A multiplate clutch outer part is formed by pressing a steel plate. The multiplate clutch outer part includes: an end wall portion; and a cylindrical portion having its one end formed continuously with the outer peripheral end of the end wall portion, and opened at the other end. A bottom face of each of outer grooves is formed to be an inclined face which is getting far away from an axis of the cylindrical portion toward the open end of the cylindrical portion. Arc faces formed at inner corners of each of the outer grooves has an increasing radius of curvature toward the open end of the cylindrical portion. Thus, there is provided a multiplate clutch outer part for which press working capable of minimizing ironing resistance can be performed to reduce defective forming rate.
    • 通过压制钢板形成多个离合器外部部件。 多片离合器外部部分包括:端壁部分; 以及圆筒部,其一端与端壁部的外周端连续形成,另一端开口。 每个外槽的底面形成为远离圆柱形部分的轴线朝向圆柱形部分的开口端的倾斜面。 形成在每个外槽的内角处的弧面朝向圆柱形部分的开口端具有增加的曲率半径。 因此,提供了一种多片离合器外部部件,可以进行能够最小化熨烫性的冲压加工,以减少不良成形速度。
