Abstract: A seal structure includes: first and second members defining a hollow internal area of a fluid device; and a seal member fixed to the first member for sealing a gap between the first and second members. The seal member includes a sliding contact member being in sliding contact with a surface of the second member and formed of a resin. The second member includes a resin layer and a resin layer holding structure. The resin layer is formed by sliding the second member on the sliding contact member to transfer the resin forming the sliding contact member onto a sliding contact portion of the surface of the second member at which the second member comes into contact with the sliding contact member. The resin layer holding structure is a porous film formed by electric discharge surface treatment and holds the resin layer in the sliding contact portion.

Abstract translation: 密封结构包括：限定流体装置的中空内部区域的第一和第二构件; 以及固定到所述第一构件的密封构件，用于密封所述第一构件和所述第二构件之间的间隙。 密封构件包括与第二构件的表面滑动接触并由树脂形成的滑动接触构件。 第二构件包括树脂层和树脂层保持结构。 树脂层通过滑动接触构件上的第二构件滑动而形成，从而将形成滑动接触构件的树脂转移到第二构件与滑动接触构件接触的第二构件的表面的滑动接触部分上。 树脂层保持结构是通过放电表面处理形成的多孔膜并将树脂层保持在滑动接触部分中。
