    摘要： A swivel caster (1) for suitcases, items of luggage, transport containers or the like has at least one wheel (8) which is rotatably received about an axis of rotation (14), and a steering axle (6) which is arranged approximately at a right angle to the axis of rotation (14) of the at least one wheel (8) and about which the at least one wheel (8) can be steered. The aim of the invention is to reduce the transmission of vibrations, running noises and jolts and bumps onto the suitcase, the item of luggage, the transport container or the like. The swivel caster (1) comprises an elastic damping element (7) which is mounted between the wheel (8) of the swivel caster (1) and a fastening element (3) of the swivel caster (1) on the suitcase side.

    摘要： A base member for swivel caster comprises a fixed base, a rotation base and a hollow staff. The fixed base includes a ring member, and a plurality of first raceways lathed in an inward surface of the ring member. A support cavity is defined through a center of the rotation base. Assembling holes are defined in a connecting portion and communicate the support cavity and the second raceways. During assembly, a plurality of rolling balls are extended through the assembling holes and loaded into the first raceways and a second raceways. Then a plurality of biasing balls is loaded into the assembling holes. The staff is inserted into the support cavity and blocks the assembling holes. The rolling balls contact the biasing balls instead of fixed components whereby the rolling balls swivel and rotate smoothly.
