<p>PROBLEM TO BE SOLVED: To provide a stroke sensor capable of suppressing a large difference between a detected stroke position and an actual stroke position, and an actuator and a rear wheel steering apparatus including the stroke sensor.SOLUTION: A stroke sensor 63 includes a bridge circuit configured by first and second resistors 81, 82 connected to ground terminals 86, 88 becoming ground potential, a common resistor 83 connected to a power supply terminal 90 becoming high potential, a first contact body 91 brought into contact with the first resistor 81 and the common resistor 83, and a second contact body 92 brought into contact with the second resistor 82 and the common resistor 83. The first contact body 91 and the second contact body 92 are coupled with each other by a coupling member 93 so as to be reciprocated in accompany with a movable iron core while keeping an interval in a stroke direction at a predetermined interval. When the other voltage value is not changed even when either one voltage value generated in voltage values of the first and second contact bodies 91, 92 is changed, an ECU 71 determines that the other voltage value is abnormal.</p> |
