In one or more embodiments, a shielding device is provided to shield a bore of a shaft against surface treatment, the shielding device including a sleeve to be at least partially received within the bore, the sleeve defining on its side wall a through-aperture and being of a first cross-sectional dimension when the through-aperture is at a rest position, and a pin to be at least partially received within the sleeve, the sleeve being of a second cross-sectional dimension greater than the first cross-sectional dimension when the through-aperture is at an expanded position with the pin being at least partially received within the sleeve.

Method and device of surface-treating a metallic part

A steering system comprises a first engagement member; a second engagement member to be engaged with the first engagement member; a supporting portion to support the second engagement member; and an elastic member at least partially enclosed in the supporting portion to apply a preload to the second engagement member and absorb an impact load. The elastic member has a first deformation under a first load and at least a second deformation under a second load greater than the first load, and a ratio of the first load to the first deformation is less than a ratio of the second load to the second deformation.
