    • PROBLEM TO BE SOLVED: To provide a vibration-proof rubber member having a small frictional resistance against a mating member and high wear resistance of a coating film, and to provide a method of comparatively easily manufacturing the same.SOLUTION: A vibration-proof rubber member 3R includes: a rubber elastic body 32R made of a self-lubricating rubber containing an elastomer 321R and a bleeding lubricant 322R; a coating film 33R covering at least a part of a sliding inner surface disposed inside of a sliding face out of a surface of the rubber elastic body 32R, and containing a resin 330R having mercapto groups and a solid lubricant including polytetrafluoroethylene particles 335R and ultrahigh-molecular-weight polyethylene particles 336R, and deformable following deformation of the rubber elastic body 32R; and a lubricating film 34R covering at least a part of a surface of the coating film 33R, including the bleeding lubricant 322R passing from the rubber elastic body 32R through the coating film 33R and bleeding out on the surface of the coating film 33R, and forming at least a part of the sliding face.
    • 要解决的问题:为了提供对配合构件具有小的摩擦阻力和涂膜的高耐磨性的防振橡胶构件,并且提供一种相对容易制造的方法。解决方案:防振橡胶 构件3R包括:由含有弹性体321R和渗出润滑剂322R的自润滑橡胶制成的橡胶弹性体32R; 涂覆膜33R,其覆盖从橡胶弹性体32R的表面设置在滑动面的内侧的滑动内表面的至少一部分,并且包含具有巯基的树脂330R和包含聚四氟乙烯粒子335R和超高分子量聚合物的固体润滑剂, 分子量聚乙烯颗粒336R,并且随着橡胶弹性体32R的变形而变形; 以及覆盖涂膜33R的表面的至少一部分的润滑膜34R,其包括从橡胶弹性体32R经过涂膜33R通过的渗出润滑剂322R,并在涂膜33R的表面上渗出,形成 滑动面的至少一部分。
