PURPOSE:To enhance the slidability of a chute, by adding fluororesin powder, electroconductive material powder and glass powder in liquid unsaturated polyester so that the thus obtained material is applied to the sliding surface of the chute. CONSTITUTION:Fluororesin powder, electroconductive material powder such as aluminum powder or the like, and glass powder and glass power of about 10-100mu or pulverized glass fiber powder are mixed with and dispersed in liquid unsaturated polyester to obtain a mixture which forms a hardened layer 3 on the bottom plate 2 of the chute 1. With this arrangement it is possible to reduce the frictional coefficient of the chute to lower the adhesion of the chute, thereby it is possible to lower the adhesion of the friction coefficient of the sliding surface and it is possible to prevent electrostatic charge. With this arrangement it is possible to enhance the electrostatic electrical charge, and to enhance the slidability of the sliding surface.
