Abstract
A method for processing a rubber surface and a sealing member treated with the method. In the first mode, a rubber surface is formed with a large number of small dimples in a regularly dotted pattern by irradiating laser beams from a laser irradiation device. In the second mode, a skin layer of the rubber surface is removed by irradiating laser beams from the laser irradiation device. In the third mode, the first mode and the third mode are combined. A sealing member comprises rubber including a seal lip part for elastically and slidably contacting a counterpart member, wherein a sliding contact surface of the seal lip part contacting the counterpart member is treated with one of the first, the second and the third modes of the method for processing a rubber surface.
