PURPOSE:To maintain low friction at the slide surface of the captioned belt during a long period of time by adsorbing, to porous particles, lubricating agent poor in mutual solubility with rubber but suitable for applying surface smoothness to the rubber surface, and forming a sliding surface by means of rubber thus dispersed and compounded. CONSTITUTION:As the belt slide surface S comprise rubber layer formed by adsorbing lubricating agent poor in mutual solubility with rubber to porous particles and dispersing same, bleeding of the lubricating agent to the belt slide surface at is carried out a substantially low speed during a long period of time. As a result, the belt slide surface S can maintain the substantially fixed small coefficient of friction during a long period of time, so as to reduce the noise at the time of using the belt and improve alignment. |
