Abstract

PURPOSE: To prevent a fluid from leaking from a sliding surface by providing one or both surfaces of the sliding portion of a synthetic resin appliance with minute recesses and projections and filling a sliding oil such as silicone in the minute recesses.
CONSTITUTION: One or both surfaces of the sliding portion of a synthetic resin appliance such as a cock are provided with minute recesses and projections, a sliding oil such as silicone is filled in the minute recesses, and a fluid seal for the sliding portion is provided by utilization of the elasticity of the resin at the minute projections. The projections are in the expanded state where the gap between the sliding surfaces is large and are in the yielded state where the gap is small. This condition is maintained by the elasticity of the projections even when a valve rotates relative to a valve case; because the sliding oil is always contained in the minute recesses, the oil holding property of the sliding surface is good and fluid seal is ensured.
