ABSTRACT:
A wheel assembly for an exerciser includes a tubular ring-mounting member having a plurality of axially extending slots at an open inner end portion thereof so as to define a plurality of tapered flexible jaws. A wheel-bearing tube has an open outer end inserted into the ring-mounting member. A retaining ring has an internal thread unit for engaging the external thread unit of the jaws, and an inclined pressing section for pressing the jaws against the wheel-bearing tube so as to fasten the ring-mounting member to the tube. A wheel ring is sleeved on the ring-mounting member between an inner outward flange unit on the jaws and an outer outward flange unit of the ring-mounting member. The inner outward flange unit can be compressed so as to permit entry of the wheel ring into the space between the inner and outer outward flange units. The wheel ring may be provided with a key secured to the inner surface thereof and engaging one of the axially extending slots of the ring-mounting member so as to prevent relative rotation between the wheel ring and the ring-mounting member when the exerciser is in use. When it is desired to transport the exerciser, the wheel ring on which no key is provided can be mounted rotatably on the ring-mounting member.
