ABSTRACT:
To allow an elevating body (17) in a clean robot (RB) installed in a clean room (R) to be located outside frames (4) without protruding from a swivel base (2) in order to enable the elevating body to be assembled and maintained easily and to ensure a wide elevating stroke. Two hollow frames (4, 4) extend vertically from the right and left sides of the rear of a swivel base (2) so as to be approximately symmetrical, a cover (9) is mounted between the frames (4, 4) and an elevating body (17) having a robot body (20) at its tip is accommodated in an elevating space (13) in the cover (9) and supported by rails (15) in the frames (4) so as to travel upward and downward. A blower (39) for air suction is located on the swivel base (2) and in front of each frame (4) to suck and exhaust the air in the elevating space (13) in the cover 9 via a suction port (36) allowing the elevating space (13) and the space in each frame (4) to communicate mutually and an exhaust port (40) to be opened in the front surface of the lower end of each frame (4).
