To provide a fluid force feed device inhibiting drop of a lifetime of a component and drop of performances due to sliding, and continuing stable operation efficiently for a long period of time.
This fluid force feed device includes an inner circumference wall 3a forming a spherical space 3, a disk body 4 concentric with the spherical space 3 and keeping sliding contact with the inner circumference wall 3a, a conical body 5 having an apex on the center of the spherical space 3, and a partition plate 6 projecting from and retracting in a groove 9 formed on the conical body 5. A region covering at least an outer circumference of the disk body 4 and an outer circumference of an end part of the partition plate 6 is formed as one unit on the inner circumference wall 3a.
