Claims

[Scope of utility model registration request]

a female threaded nut part fixed to the piston of the piston/cylinder device and having a female thread on the inner periphery;
It has a male thread that can be threadedly engaged with the female thread, one end of which extends into an axial hole formed in a piston rod portion fixed to the piston, and the other end of which is rotatably connected to the head side flange of the device and has a shaft. a male threaded rod part supported so as not to be movable in any direction; a screw feeding part for converting the rotation of the male threaded rod into an axial movement shorter than the piston stroke of the device; and an axial movement part of the threaded feeding part. A cylinder with a sensor, comprising: a sensor shaft of a linear sensor connected so as to be connected to the cylinder;
