摘要： Lubricating oil supply holes are formed in a first member fitted to first annular plates by splines, and lubrication oil grooves are formed in the first annular plates. At each spline to which the lubricating oil groove in each first annular plate corresponds, the lubricating oil groove does not overlap with the spline on at least either the front surface side or the rear surface side of the first annular plate. Therefore, lubricating oil flowing out of the lubricating oil supply holes does not flow toward the outer periphery of the first annular plates in a concentrated manner but flows in a distributed manner from the inner periphery to the outer periphery of the first annular plates. As a result, flows of the lubricating oil suppress force that acts in the direction in which the second annular plates are caused to be in contact with friction materials of the first annular plates, and thereby drag torque is reduced.

摘要： Lubricating oil supply holes are drilled into a first member that is fitted to a plurality of first annular plates by a spline. Of splines to which each lubricating oil supply hole corresponds, lubricating oil grooves provided in the plurality of first annular plates do not overlap the splines on at least one of the front and rear surfaces of the first annular plates, and therefore lubricating oil flowing out of the lubricating oil supply holes is dispersed in a circumferential direction and flows from the inner periphery to the outer periphery of the first annular plates, rather than gathering in each lubricating oil groove and flowing in an outer peripheral direction. As a result, a force generated by an axial lubricating oil flow, which acts in a direction for causing the second annular plates to contact friction materials on the first annular plates, is suppressed, leading to a reduction in drag torque.
