To provide an auxiliary-machine driving device that is good in power transmission efficiency with less storing space.
A motor 80 for driving an auxiliary machine is mounted on the one end of the crankshaft 12 of an engine 10. The motor 80 is a flat motor with a rotor 81 and a stator 83 arranged in such a way as to face each other in the axial direction of an output shaft 82 to which the rotor 81 is fixed. A plurality of permanent magnets are arranged on the surface of the rotor 81 facing the stator 83. Three-phase coils for forming a rotating field are wound on the stator 83. The output shaft 82 is supported in such a way as to be rotatable freely by an outer casing 84 via bearings 841. The one end 821 of the output shaft 82 is coupled to that of the crankshaft 12 via a clutch 16, while a pulley 823 for driving the auxiliary machine is mounted on the other end 822 of the output shaft 82.
