To provide an auxiliary power unit capable of suppressing an increase in power source performance of auxiliary power, and a steering device.SOLUTION: An auxiliary power unit 40, which has auxiliary power 100, is provided on a power supply path between a main power supply 60 and a motor 20. A maximum discharge voltage, which is power source performance of the auxiliary power 100, is set on the basis of electric power required to minimally operate the motor 20 so that an EPS can fulfill a minimum function. The maximum discharge voltage, which is the power source performance of the auxiliary power 100, is set lower than a battery voltage that is power source performance of the main power supply 60.SELECTED DRAWING: Figure 2

    【課題】補助電源の電源性能の高性能化を抑えることができる補助電源装置及びステアリング装置を提供する。【解決手段】主電源60とモータ20との間の給電経路上に設けられてなる補助電源装置40は、補助電源100を有している。補助電源100の電源性能である最大の放電電圧は、EPSが最低限の機能を発揮するべくモータ20が最低限の動作をするのに必要とされる電力を基準として設定されている。補助電源100の電源性能である最大の放電電圧を主電源60の電源性能であるバッテリ電圧よりも低くしている。【選択図】図2
