Abstract

PURPOSE:To prevent scattering dust by forming a pocket unit on an outside of a seal material having axial supporting portion on its outside and coupling an intake means to the pocket unit. CONSTITUTION:A bearing cover 50 is sticked to a bearing unit of a first arm 11 in the condition where an O-ring 51 is interposed on the outer circumference. The inner circumferential part of the cover is contacted indirectly to an outer peripheral face of a hollow shaft 21 by a seal member 52 to form an annular pocket unit 53 integrally on the lower portion. The pocket unit 53 is connected to a suction tube 44 by a communicating passage 55 and a piping joint 56. As the suction tube 44 sucks air of the pocket unit 53, even if dust is generated, the dust is not scattered in a room suck as clean room.
