Free wheel hub mechanism

A free wheel hub mechanism comprising:

• a body secured to a wheel,
• an inner race secured to an axle shaft and rotatable therewith, said inner race having at outer periphery thereof a plurality of cam surfaces,
• a cage arranged between said body and said inner race and having a plurality of openings in which rollers are positioned,
• said rollers being outwardly urged by said cam surfaces so as to be squeezed against said body when said inner race rotates with said shaft together as one body, thereby causing said wheel to rotate together with said inner race, and
• means for restraining rotation of said cage, said restraining means including a plurality of shoes between which a plurality of cantilever projections provided on an innermost portion of said cage are arranged, a shoe receiving member secured to a non-rotatable spindle sleeve which houses said shaft therein and having a receiving surface on which said shoes are slidably received, and an annular spring means urging said shoes against said receiving surface and maintaining said shoes in their proper position,
• whereby after said shoes and said shoe receiving member are assembled by said spring means, said shoe receiving member is secured to said spindle sleeve, and thereafter said projections of said cage which is assembled within said body between said body and said inner race, are positioned between said plurality of shoes.
