1. A stroke operation diagnosis supporting device for a hydraulic cylinder, the stroke operation diagnosis supporting device comprising:

  • movable portions sequentially supported rotatably to a vehicle main body;

    hydraulic cylinders each disposed between the vehicle main body and the movable portion or between the movable portions and rotatably supporting the movable portions;

    a stroke sensor provided for the hydraulic cylinder and measuring a stroke length of the hydraulic cylinder;

    a reset sensor measuring a reset reference point at which a measurement value of the stroke length obtained by the stroke sensor is reset;

    a stroke end detection process unit detecting a stroke end position of the hydraulic cylinder;

    a calibration process unit calibrating the measurement value of the stroke length upon the detection of the reset reference point and/or the stroke end position; and

    a monitor displaying on a screen at least the measurement value of the stroke length obtained by the stroke sensor and a calibration state obtained by the calibration process unit, wherein the monitor displays continuous time change of the measurement value of the stroke length obtained by the stroke sensor.
