Constitution: a ceramic sliding part of a structure in which a sliding surface-forming ceramic member (1) is combined with a metal base material (2), the crowning rate of the sliding surface being 0.1 % to not less than 0.4 % of a maximum length of the joint surface of the ceramic member. The ceramic material has a 4-point bending strength in accordance with JIS R1601 of not lower than 500 MPa, and the metal base member comprises mainly steel, and preferably a metal material having martensite texture in at least the outer surface thereof and a hardness of HRC > 45. A ceramic sliding part uses an intermediate layer of a metal or cermet. The combining of a sliding surface member of a crown-shaped ceramic material and the forming of a metal base member are done simultaneously, or the sliding surface of the metal base member is hardened by heating after it has been combined with the sliding surface member. Effect: a sliding part having a high crowning rate in which defective portions including cracked portions rarely occur can be provided at a low price.

摘要： The transverse cross section of a shaft (1) perpendicular to the axis O has a shape defined by closed curves having a plurality of maximum points (M1, M2, M3) at which distances from the axis O which is located at the center become maximum and a plurality of minimum points (N1, N2, N3) at which the distances from the axis become minimum. The transverse cross section has a groove-forming region in which at least one groove (1b1) is formed between maximum points M1 and M2. When a bearing (2) rotates counterclockwise relative to the shaft (1), the groove (1b1) is so arranged that the outer peripheral length (a1) in the forward direction of rotation is longer than the outer peripheral length (b1) in the reverse direction of rotation. There is thus obtained a dynamic-pressure gas bearing structure which prevents scuffing between the shaft and the bearing by shifting the shaft and the bearing into a noncontact state at a low rotational speed.
摘要翻译：垂直于轴线O的轴（1）的横截面具有由具有多个最大点（M1，M2，M3）的闭合曲线限定的形状，在该距离处距离位于中心处的轴线O的距离变得最大以及与轴的距离变为最小的多个最小点（N1，N2，N3）。横截面具有沟槽形成区域，其中在最大点M1和M2之间形成至少一个凹槽（1b1）。当轴承（2）相对于轴（1）逆时针旋转时，槽（1b）布置成使得在正向旋转方向上的外周长度（a1）比外周长度（b1）长反转方向。由此得到动压气体轴承结构，其通过将轴和轴承以低转速移动到非接触状态来防止轴与轴承之间的磨损。
