摘要： In a power supply apparatus, a power supply circuit includes a primary power supply circuit including a high-voltage battery and a step-down circuit for stepping down the voltage of the high-voltage battery, and a secondary power supply circuit including a low-voltage battery and a step-up circuit for stepping up the voltage of the low-voltage battery. The primary power supply circuit and the secondary power supply circuit are connected in parallel. An output voltage of the secondary power supply circuit is set to be lower than an output voltage of the primary power supply circuit. When the output voltage of the primary power supply circuit becomes lower than a target voltage of the secondary power supply circuit, the voltage stepped-up by the step-up circuit is supplied to a motor drive circuit. Accordingly, power supply backup of an electric power steering apparatus can be performed at low cost.

摘要： In a power supply apparatus 40, a power supply circuit is formed by a primary power supply circuit 50 which includes a high-voltage battery 51 and a step-down circuit 55 for stepping down the voltage of the high-voltage battery 51, and a secondary power supply circuit 60 which includes a low-voltage battery 61 and a step-up circuit 70 for stepping up the voltage of the low-voltage battery 61. The primary power supply circuit 50 and the secondary power supply circuit 60 are connected in parallel. An output voltage of the secondary power supply circuit 60 is set to be lower than an output voltage of the primary power supply circuit 50. When the output voltage of the primary power supply circuit 50 becomes lower than a target voltage of the secondary power supply circuit 60, the voltage stepped-up by the step-up circuit 70 is supplied to a motor drive circuit 32. Accordingly, power supply backup of an electric power steering apparatus can be performed as low cost.

摘要： A vehicular rear wheel steering device includes a housing, a rod being non-turnable with respect to the housing and movably supported in an axial direction of the rod, and a conversion mechanism arranged between the rod and the housing to convert a rotation of a rotational drive device to a drive force in the axial direction. The housing includes a tubular first bush disposed at a first end and a tubular second bush at a second end. Each bush is slidably engaged to an outer periphery of the rod and supports the rod to be movable in the axial direction. A rod supporting rigidity of the first bush is lower compared to that of the second bush. The first bush is arranged with an elastic body that deforms in a radial direction of the rod. The second bush is arranged with an inner periphery protrusion at which the rod tilts.
