PROBLEM TO BE SOLVED: To provide a stroke sensor system, or the like that cannot be easily affected by noise, and can easily increase precision in the amount of stroke to be outputted.SOLUTION: A stroke sensor system includes: an outer casing 712 tubularly formed and positioned at a body side; a guide 763c tubularly formed, positioned at a wheel side, and relatively moved to the outer casing 712; and a travel distance derivation part for acquiring travel distance when the outer casing 712 and the guide 763c are relatively moved. A coil 763j is provided in the guide 763c. The travel distance derivation part includes: an even number of capacitors electrically connecting to the coil 763j and composing an LC resonance part; and an even number of excitation parts for relatively moving the outer casing 712 and the guide 763 so as to excite an oscillation waveform outputted by an LC resonance part. The even number of capacitors and the even number of excitation parts are respectively divided into the same numbers so as to constitute a balance circuit, and the travel amount is acquired based on the oscillation waveform.SELECTED DRAWING: Figure 3
