摘要： To provide a stroke measuring method of the hydraulic cylinder of the hydraulic excavator and a hydraulic excavator which can accurately measure the stroke length of the hydraulic cylinder for driving a working machine. A hydraulic excavator 1 includes a ba portion, a movable portion, and a hydraulic cylinder, a position nsor 10 includes a rotary encoder 20, and a controller 30. The rotary encoder 20 includes a light emitter 26, a light receiving portion 27, and a disk portion 25 that rotates in synchronization with the rotation of the movable part to a plurality of transmissive portions 25a are dispod and the ba portion. Is generated depending on the rotation angle of the disk portion 25, and bad on the pul signal the rotation angle of the disk portion 25 associated with the rotation angle of the movable part to the transmitted luminous multiple transmitting portions 25a receiving part 27 is output. The control unit 30 measures the stroke length of the hydraulic cylinder by correcting the stroke length of the displacement measured by the position nsor 10 bad on the pul signal outputted from the rotary encoder 20.
