ABSTRACT:
A free wheel hub mechanism is made up of a body secured to a wheel and an inner race rotatable with an axle shaft and having a plurality of cam surfaces at its outer periphery, a plurality of rollers held by a cage arranged between the body and the inner race, the rollers being urged ouwards by the cam surfaces so as to be squeezed against the body when the inner race is rotated with the shaft. The squeezing of the rollers causes them to rotate with the inner race thereby to rotate the wheel. Also provided are means for restraining the rotation of the cage, including a plurality of shoes between which a plurality of projections provided on an innermost portion of the cage are arranged, a shoe receiving member secured to a non-rotatable spindle sleeve which houses the shaft and which has a receiving surface on which the shoes may slide, and an annular spring means urging the shoes against the receiving surface. In assembly, the shoes and shoe receiving member are assembled with the spring means, the shoe receiving member is secured to the spindle sleeve, and thereafter the projections of the cage, which is assembled between the body and the inner race, are positioned between the plurality of shoes.
