ABSTRACT:
A caster wherein the underside of the web of the wheel frame is formed with a socket for a fulcrum which is integral with and is located between two arms of a wheel brake. One arm of the brake carries a shoe which can be moved into frictional engagement with the wheel in response to downward movement of a post forming part of an actuator which is concealable in the leg of a piece of furniture or the like. The other arm of the brake is biased in a direction to move the shoe away from the wheel by a tongue of a springy plate-like member which is affixed to the underside of the web and further comprises two prongs which retain the fulcrum in the socket. The hub of the wheel is concealed behind caps which are carried by the frame, and the fulcrum as well as the plate-like member and the brake are also concealed from view.
