Claims (4)

An electric motor or hydraulic actuator for assisting steering is provided, and a detection signal from a dedicated or shared detector is given to an input terminal pulled up or pulled down through a first resistor, and the electric motor is based on the given detection signal Alternatively, in a power steering device that drives and controls a hydraulic actuator ,
One or more second resistors for pulling up or pulling down the input terminal, one or more switching elements for bringing the second resistance into an energized state or a non-energized state, and an external setting. A power steering device comprising setting means for setting on / off. 2. The power steering apparatus according to claim 1, further comprising a switching element that causes the first resistor to be in an energized state or a non-energized state, and a setting unit that receives an external setting and sets the on / off state of the switching element. The setting unit includes a nonvolatile memory that stores the setting by communication from the outside, and is configured to set on / off of the switching element in accordance with the setting stored in the nonvolatile memory. Item 3. The power steering device according to Item 1 or 2. The power steering apparatus according to any one of claims 1 to 3, wherein the detector is a steering angle detector that detects a steering angle of a steering member.
