An auxiliary power supply unit (1) includes an auxiliary power supply device (71) and a downstream power supply line group (72) connecting the auxiliary power supply device to motor units (13, 32). The auxiliary power supply device (71) includes: an auxiliary power supply (111) provided on a power supply path to assist with power supply from an external power supply (45) to the motor units; and a switching circuit (114) configured to switch the connection state of the auxiliary power supply to the power supply path. The connection state of the auxiliary power supply includes a boost state in which the auxiliary power supply is connected in series with the external power supply between the external power supply and the motor units. The downstream power supply line group (72) includes branch first downstream drive lines (161, 162) and branch second downstream drive lines (163, 164). Each of the upstream ends of the branch first downstream drive lines and the branch second downstream drive lines is connected to the power supply path at a position downstream of the auxiliary power supply.
