Abstract

PURPOSE:To prevent floating dust present in an environmental atmosphere from winding around the outer periphery of a roller, by forming an air flow jetted from an air gap along the whole outer periphery of the roller. CONSTITUTION:A roller 22 is supported on a minor axis 11 of a base member 10 and air is fed from an air feed port 15, passed through an air chamber 14 and air gap (g) and annularly jetted. Thereby an air flow directing to the outer periphery of the roller can be formed. The air flow is also present on the whole outer periphery of the roller.
