    摘要: The invention provides a rolling/sliding part that can elongate the service life and can increase the static load capacity to improve the indentation resistance to an indentation due to plastic deformation during rest and low-speed rotation. The rolling/sliding part is formed from a steel that contains C: 0.7 to 0.9% by weight and Cr: 3.2 to 5.0% by weight and has a surface layer portion of which surface is carburized. An area ratio of total precipitated carbide of the surface layer portion is set in the range of 15 to 25%. Of the total precipitated carbide present in the surface layer portion, 50% or more by area ratio of carbide is rendered a M7C3 type and/or M23C6 type. An average grain diameter and a maximum grain diameter of the surface layer portion are set in the range of 0.3 to 0.6 μm and at 4 μm, respectively. The surface hardness is set at 62 or more by Rockwell hardness C. A solid solution carbon amount in residual austenite of the surface layer portion is set in the range of 0.95 to 1.15% by weight.

    摘要: An oil pressure controller of an automatic transmission which is capable of supplying engaging pressures to hydraulic servos of two frictional engaging elements which require different engaging pressures by a single pressure governing valve with a good pressure governing accuracy. The oil pressure controller comprises a hydraulic power source (10), hydraulic servos (70 and 80), signal pressure generating means (20), a pressure governing valve (30) for governing an oil pressure (P.sub.s) from the hydraulic power source (10) by a signal pressure (P.sub.ACC) and a control valve (40). The pressure governing valve (30)has a pressure receiving face A.sub.1 to which the signal pressure is applied, a pressure receiving face A.sub.2 to which the engaging pressure (P.sub.s) is fed back in the opposite direction and a pressure receiving face (A.sub.3) for selecting whether the feedback of the engaging pressure is present or not in order to change the control gain of the pressure governing valve (30)in response to the change of the control valve (40) for selecting the hydraulic servo (70 or 80) to which the oil pressure is supplied.

    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.
