Abstract
Abstract A one-way clutch device comprises a first member having an annular track surface, a second member having an annular track surface concentric with the annular track surface of the first member, a ring space defined between the track surface of the first member and the track surface of the second member, torque transmitting members disposed in the ring space and tiltable into wedge engagement with both of the track surfaces to connect the track surfaces together for rotation in unison, a first annular retaining member engaged with the torque transmitting members to hold the same, the first retaining member being disposed concentrically with and adjacent to the track surface of the first member and engaged with the first member to prevent axial slippage thereof, a second annular retaining member engaged with the torque transmitting members to hold the same, the second retaining member being disposed concentrically with and adjacent to the track surface of the second member, and a spring interposed between the first retaining member and the second retaining member and biasing the two retaining members away from each other.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
A one-way clutch device comprising: an inner race; an outer race disposed radially outside of said inner race and concentric with said inner race; wedge means tiltably disposed between said inner and outer races for transmitting a torque from one of said races to the other, said wedge means wedge-engaging said races when tilted to connect both races for rotation in unison; inner and outer retainers concentric with said races for retaining said wedge means between said races and facing said inner and outer races, respectively; and spring means interposed between said retainers for urging said wedge means toward wedge engagement with said races; one of said retainers having a radially projecting flange portion extending into a groove provided on the corresponding facing race to engage said race and prevent said one retainer from tilting and moving in an axial direction.
Claim 2
Dependent Claim
141 words
A one-way clutch device comprising: an inner race; an outer race disposed radially outside of said inner race and concentric with said inner race; wedge means tiltably disposed between said inner and outer races for transmitting a torque from one of said races to the other, said wedge means wedge-engaging said races when tilted to connect both races for rotation in unison; inner and outer retainers concentric with said races for retaining said wedge means between said races and facing said inner and outer races, respectively; and spring means interposed between said retainers for urging said wedge means toward wedge engagement with said races; one of said retainers having a radially projecting flange portion extending into a groove provided on the corresponding facing race to engage said race and prevent said one retainer from tilting and moving in an axial direction.
Claim 3
Dependent Claim
28 words
A device according to claim 1, wherein the other of said retainers has an end flange which extends toward said corresponding facing race engaged with said one retainer.
Claim 4
Dependent Claim
23 words
A device according to claim 2, wherein said end flange extends into contact with said corresponding facing race engaged with said one retainer.
Claim 5
Dependent Claim
126 words
A one-way clutch device comprising: an inner race; an outer race disposed concentrically about said inner race; torque transmitting means disposed between said inner and outer races and tiltable into wedge engagement with said inner and outer races for connecting the races together for one-way rotation in unison; inner and outer annular retainers disposed between and concentric with said inner and outer races and retainably engaging said torque transmitting means; and spring means disposed between said retainers for urging said torque transmitting means toward wedge engagement with said races; at least one of said retainers and one of said races having mutually cooperable means for engaging said one retainer with said one race to prevent axial slippage of said one retainer relative to said one race.
Claim 6
Dependent Claim
126 words
A one-way clutch device comprising: an inner race; an outer race disposed concentrically about said inner race; torque transmitting means disposed between said inner and outer races and tiltable into wedge engagement with said inner and outer races for connecting the races together for one-way rotation in unison; inner and outer annular retainers disposed between and concentric with said inner and outer races and retainably engaging said torque transmitting means; and spring means disposed between said retainers for urging said torque transmitting means toward wedge engagement with said races; at least one of said retainers and one of said races having mutually cooperable means for engaging said one retainer with said one race to prevent axial slippage of said one retainer relative to said one race.
Claim 7
Dependent Claim
28 words
A device according to claim 4, wherein said cooperable means comprises a groove in said one race and a portion of said one retainer extending into said groove.
Claim 8
Dependent Claim
24 words
A device according to claim 5, wherein said portion of said one retainer includes a flange portion at one end of said one retainer.
Claim 9
Dependent Claim
33 words
A device according to claim 6, wherein the other of said retainers has a flange at an end opposite said one end of said one retainer, said flange extending toward said one race.
