Abstract
A swivel wheel assembly which is easy to assemble and convenient for use includes a tube plug inserted into a tube leg, a pivot pin inserted into the tube plug and a rotary member rotatably secured on the pin. The rotary member supports a shaft and pair of wheels. By using a hard material for the pin, a softer material for the rotary member and a still softer material for the tube plug, friction is reduced. The plug, pin and rotary member are assembled without the use of fasteners. The rotary member includes a resilient flexible member with a key received in a circumferential groove of the pivot pin.
