Though numerous studies of disc friction of smooth surface were already carried out, but the detail discussions of disc friction of rough surface have not still been performed. Experiments were carried out for both cases of discs with smooth surface, and rough surface consisting of sand-grain of various size and shape. The main results obtained may be sumarized as follows : 1) For a certain value of clearance, the resistance coefficient takes a minimum value. 2) Resistance moment of cast-iron disc is equal to that of the roughness IV surface of disc (average dia. of sand-grain is 0.04 mm). 3) Let C_<f1>, C_<f2> and C_<f3> be the increment value of resistance coefficient of a rough disc in rough vessel, rough disc in smooth vessel and smooth disc in rough vessel, respectively, we obtain the following relation, C_ <f1>≒2 C_ <f2>≒4 C_<f3>, where the increment value means the increase to resistance coefficient of smoth disc in smooth vessel.
