摘要： A clutch drum for a multi-plate clutch in an automatic transmission is provided at an inner periphery thereof with splines by which friction plates are engaged. Each of the splines has a tooth tip having two circumferential ends. Only one of the circumferential ends of the tooth tip has a curved surface. The splines of the clutch drum may be formed by form rolling using a tooth forming tool including a tooth root. The tooth root may have a circumferentially leading end and a circumferentially trailing end in a rotational direction, with only the circumferentially leading end having a curved surface.

摘要： A wet-type multiplate clutch has an outer circumferential drum section, an inner circumferential hub, a pressing member, and a clutch engagement unit composed of plural friction plates and separator plates alternately arranged between the drum section and the hub. One of mutually-contacting walls of the drum section and clutch engagement unit and one of mutually-contacting walls of the unit and pressing member are provided at their predetermined contact areas with inclinations such that, when the clutch is out of engagement, the mutually-contacting walls of the drum section and unit and the mutually-contacting walls of the unit and pressing member form wedge-shaped spaces between them, respectively, as viewed in a radially-extending, axial cross-section, said wedge-shaped spaces being gradually reduced in widths thereof toward an exterior in a radial direction and, when the clutch is in engagement, the mutually-contacting walls of the drum section and unit and the mutually-contacting walls of the unit and pressing member radially extend at right angles relative to a central axis of the wet-type multiplate clutch and are in close contact with each other, respectively.
