という難点がある。 However, as the actuator 5 moves up and down, the piston 6 rotates, albeit slightly. Although the displacement meter 4 can be used in either the vertical or horizontal direction, the gap between the scale and the sensor must be maintained at 2 mm ± 0.1, but due to the minute rotation of the piston 6, The problem is that the relative positions become distorted.

減しうるものである。 In the present invention, as described above, the sensor is attached to the piston shaft of the actuator via a sleeve rotatably mounted around the axis, and the guide member attached to the sensor is attached to the guide member parallel to the piston shaft. Since it is installed slidably,
Even if the piston rotates as the actuator moves up and down, the rotational movement of the piston is absorbed by the sleeve, and the displacement meter sensor uses the guide member and guide rail attached to the sensor as a guide. It moves smoothly in a direction parallel to the piston axis, and the sensor and scale are always maintained at a predetermined gap, allowing for highly accurate measurements.
Further, according to the present invention, the structure is simple and manufacturing costs can be reduced.
