The appearances and the change of the frictional force of a system with two hard spheres in a twodimensional rectangular box are discussed. With controlling the pressure or the supply of energy from the wall, the solid-like state, the solid-liquid temporal coexistence state, and the liquid-like state are observed. The frictional force and the fluidity of the system are measured under the shear. By varying the shear, a marked change of frictional forces is observed with similar characteristics to those of the static and dynamic frictions of a solid-on-solid system. Moreover, the relationship between the above frictional force and the shear is found to show strong temperature dependency. The hysteresis loop in the frictionvelocity relation on granular layers [S. Nasuno et al.: Phys. Rev. Lett. 79 (1997) 949] is discussed on the base of these results.
