Claims

[Scope of utility model registration request]

The adjustment screw is rotated and moved in the axial direction, and the set pressure of the valve is adjusted by changing the biasing state of the pressure setting spring by the movement, and the axial movement of the adjustment screw is controlled by an actuator. In the drive unit for setting the pressure of a valve, the output shaft of the actuator and the adjusting screw are connected by forming the upper part of the adjusting screw into a cylindrical shape and aligning the axial center in the axial direction of the cylindrical portion. forming a groove through which the output shaft of the actuator is slidably inserted into the cylinder; and attaching a roller having a diameter slightly smaller than the width of the groove to a side surface of the output shaft;
A driving force transmitting unit for a pressure setting drive unit of a valve, characterized in that the roller is movable within the groove in the axial direction of the adjusting screw.
