Hydraulic cylinder with stroke position detection function

摘要

The object of the present invention is to measure the stroke position measured by the stroke position detection sensor when the stroke position is detected by the stroke position detection sensor in which the roller support portion supporting the rotating roller is inclined and the reset position detection sensor resets the stroke position. To provide a hydraulic cylinder with a stroke position detection function capable of reducing an error between a stroke and an actual stroke. The rotating roller (12) that rotates with the direct movement of the piston rod (3) is supported by the roller support (13), and the stroke position of the piston rod (3) is detected based on the rotation of the rotating roller (12). And a reset position detection sensor (15) for detecting a detected part (40) corresponding to a reset position provided at a predetermined position on the surface of the piston rod (3) attached to the roller support part (13). The stroke position detection sensor (10) is provided.
