Abstract
A locking wheel useful for wheels on small vehicles. The locking wheel fits over a shaft and has a bore for receiving the end of the shaft. An outer member is connected to and spaced from the hub. A finger is adjacent to the bore and has a protrusion that extends into the bore. The finger is resilient and movable between a first and second position. The first position has the protrusion protruding into the bore and the second position has the protrusion outside of the bore with the finger being bent radially outward. The shaft has a notch or hole that receives the finger's protrusion. A locking device may selectively be placed between the outer member and the hub to prevent the finger from moving into its second position, thereby locking the hub onto the shaft.
