Abstract: A non-contact transport device includes a deflector having a flange portion provided with a plurality of nozzle grooves extending radially outward and arranged equidistantly in the circumferential direction. The nozzle grooves are each formed to be hollowed with respect to an upper surface of the flange portion so as to have an arc-shaped cross section, and constitute lead-out channels together with a flat surface of a hollow of a body. A pressure fluid is supplied through a first port of the body into the body and flows through the plurality of nozzle grooves to a workpiece holding surface along first and second curved surfaces of the hollow. As a result, the pressure fluid flowing at high speed between the workpiece holding surface and a workpiece generates a suction force exerted toward the body side, whereby the workpiece is suctioned.

Abstract: A layered nut (10) comprises a plurality of thin nuts (12) formed with through-holes (16) having almost the same diameter. On the inner peripheral surface of each thin nut (12), a plurality of screw threads (18, 38) are formed at predetermined angular spacing so as to protrude toward the inside of the through-hole (16). In this case, the thin nuts (12) are layered along the direction of the central axis (14) so that the through-holes (16) become approximately coaxial. The outer peripheral surfaces of the layered thin nuts (12) are subjected to laser welding or the like, thereby joining the thin nuts (12) and completing the layered nut (10).
