Claims
- 1. A torque transmission device comprising an outer ring, an input shaft rotatably mounted in said outer ring, said outer ring and said input shaft being formed with engaging surfaces so as to be opposite to each other, a cage rotatably mounted between said outer ring and said input shaft and formed with pockets, engaging elements mounted in said pockets and adapted to engage said engaging surfaces when said input shaft and said cage rotate relative to each other, elastic members mounted in said pockets to urge said engaging elements toward a position where they do not engage, a control shaft mounted coaxially with respect to said input shaft, said control shaft being integrally coupled with said cage, and input member integral with said control shaft and coupled with said input shaft with a gap left therebetween in the direction of rotation, and a rotation delay means for causing a relative rotation between said control shaft and said input shaft.
- 2. A torque transmission device as claimed in claim 1, further comprising a torque reversing transmission means provided between said control shaft and said cage for transmitting the rotation of said control shaft to said cage after reversing the direction of rotation.
- 3. A torque transmission device as claimed in claim 1 or 2, wherein said rotation delay means comprises a bearing having a resistance to rotation which is larger than a resistance to rotation applied to a portion at which one of said control shaft and said input shaft is supported.
- 4. A torque transmission device as claimed in claim 1 or 2, wherein said rotation delay means comprises a reduction gear unit for reducing the rotation of one of said control shaft and said input shaft and transmitting the reduced rotation to the other of them.
- 5. A torque transmission device as claimed in claim 1 or 2, wherein said rotation delay means comprises at least one rolling bearing having rolling elements and a cage for retaining said rolling elements and wherein its rotation is taken out from said cage.
- 6. A torque transmission device as claimed in claim 1 or 2, wherein said rotation delay means is kept out of contact with one of said control shaft and said input shaft.
- 7. A torque transmission device as claimed in claim 6, wherein said rotation delay means comprises a rotary member made of a conductive material and secured to one of said control shaft and said input shaft, and a magnet having both magnetic poles thereof arranged to enclose both ends of said rotary member.
