Abstract
Official abstract text for this publication.
In a sliding shaft, an outer circumferential surface of a male shaft is coated with a resin coating layer formed by a fluidized bed powder coating method by using a powder coating material containing a base resin and an aliphatic compound. A steering device includes this sliding shaft as an intermediate shaft transmitting steering force.
First claim
Opening claim text (preview).
1 . A sliding shaft comprising a male shaft and a cylindrical female shaft connected to each other slidably along an axial direction, an outer circumferential surface of the male shaft or an inner circumferential surface of the female shaft being coated with a resin coating layer, wherein the resin coating layer is formed, by a fluidized bed powder coating method, by using a powder coating material, the powder coating material containing: a base resin; and a fatty acid having 14 or more carbon atoms or a metal salt thereof, and wherein splines to be engaged with each other are respectively formed on the outer circumferential surface of the male shaft and the inner circumferential surface of the female shaft, and the male shaft and the female shaft are connected to each other to be expandable/contractible along the axial direction through engagement of the splines. 2 . The sliding shaft according to claim 1 , wherein the powder coating material contains the aliphatic compound in a ratio of 0.05% by mass or more and 0.5% by mass or less based on an amount of the base resin. 3 . The sliding shaft according to claim 1 , wherein the base resin is polyamide. 4 . The sliding shaft according to claim 3 , wherein the base resin is polyamide 610. 5 . (canceled) 6 . A steering device comprising the sliding shaft according to claim 1 as an intermediate shaft transmitting steering force.
