Driving system, mechanical tester, tire tester, load applying section and engine simulator

This two-output-shaft motor is equipped with: a cylindrical main frame; a substantially plate-like first bracket that is attached to one axial end of the main frame; a substantially plate-like second bracket that is attached to the other axial end of the main frame; and a drive shaft that runs through the hollow part of the main frame, penetrates through the first bracket and the second bracket, and is rotatably supported by bearings provided in the first bracket and the second bracket. One end of the drive shaft protrudes to the outside from the first bracket and forms a first output shaft for outputting a driving force to the outside, and the other end of the drive shaft protrudes to the outside from the second bracket and forms a second output shaft for outputting the driving force to the outside.
