To surely transport and take-out/put-in a workpiece in an enlarging trend, without lowering the efficiency of transportation and taking-out/putting-in of the workpiece.

The workpiece transporting robot is provided with a driving arm 3 and driving links 6/7, which are driven to revolve around the common axial center by different driving systems, and first/second revolving arms 4/5 which are made freely revolvable in parallel with each other to the driving arm 3 around the common axial center. The robot is also provided with first driven arms 9/10 and second driven arms 11/12 for connecting the driving arm 3 with the first/second revolving arms 4/5, and first/second reinforcing links 26/25, in which a pair of mutually freely rotatably connected reinforcing arms 27/28 are provided freely rotatably to the driving arm 3 and the first/second revolving arms 4/5 respectively and which connect the arms. Freely rotatable connection link arms are respectively provided to the mutual connection parts of each reinforcing arm in each link. Each connection link arm is connected to the driving link 3 freely rotatably at a fixed angle around the shaft.
