Abstract:
Provided is a sliding nut for a sliding screw device, a sliding screw device, and so on that are easy to manufacture and have outstanding sliding properties, including seize resistance and abrasion resistance, even under high-load conditions. A sliding nut in a sliding screw device moves relative to the screw shaft while sliding along the screw shaft as the screw shaft rotates. A nut body (73a) is made of sintered metal, and a thin resin layer (73b), made of a resin composition having a synthetic resin such as aromatic polyether ketone resin as a base resin, is formed by injection molding and serves as a thread groove section in an internally threaded surface on the body of the nut for screwing together with the screw shaft.
