BIASING FORCE ADJUSTMENT DEVICE, HYDRAULIC CONTROL VALVE HAVING THE SAME, AND METHOD OF MANUFACTURING BIASING FORCE ADJUSTMENT DEVICE

摘要

A biasing force adjustment device includes: a cylindrical component having a first thread part; a reciprocate component accommodated in the cylindrical component; a biasing portion that biases the reciprocate component in a first direction; and a biasing force adjustment component that adjusts a biasing force of the biasing portion. The biasing force adjustment component has a second thread part engaged with the first thread part so as to control the position of the biasing force adjustment component relative to the cylindrical component, and a regulation part that regulates movement of the biasing force adjustment component relative to the cylindrical component by being deformed in a radial direction by external force applied in the first direction.
