Abstract
A component mounter is provided with a nozzle shaft holder which includes a through-hole into which a nozzle shaft, a component suction nozzle being installed on the bottom end thereof, is inserted, and bearings which are disposed in two locations separated vertically on an inner circumferential surface of the through-hole and which guide the nozzle shaft in the vertical direction. In the bearings, two ring-shaped guide portions which surround an outer circumferential surface of the nozzle shaft are formed separated in a vertical direction, a grease holder, which has a larger inner diameter than the ring-shaped guide portions, is formed between the two ring-shaped guide portions, and a space surrounded by the outer circumferential surface of the nozzle shaft, the two ring-shaped guide portions, and the grease holder is filled with grease.
