PURPOSE: To provide a horizontal multi-articulated robot by which teaching work is facilitated and interference with a device to be worked or a peripheral device can be prevented.

CONSTITUTION: The base end of the first swing arm 3 is connected to a column which is vertically arranged from a base and is driven upward/downward. At the tip of the first swing arm 3, the central part, of the second swing arm 4 is connected freely rotationally. In the central part of the second swing arm 4, a servomotor 11 is stored, and in an output shaft 11b of the servomotor 11, pulleys 8A, 8B are inserted and fitted. In both ends of the second swing arm 4, flanges 5A, 5B are stored in symmetrical positions via bearings 9. A pulley 8A is inserted into a shaft 5a of the flange 5A, and a timing belt 6A is wound between this pulley 8A and the pulley 8A inserted into the output shaft 11b of the servomotor 11. In a shaft 5b of the flange 5B, a pulley 8B is inserted, and a timing belt 6B is wound between this pulley 8B and the pulley 8B inserted into the shaft 11b of the servomotor 11.
