Title:
REVERSE INPUT SHUTOFF CLUTCH, ELECTRIC VALVE TIMING ADJUSTMENT DEVICE, VARIABLE COMPRESSION RATIO DEVICE, AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026794
Kind Code:
A1
Abstract:
There is achieved a reverse input shutoff clutch of which the axial dimension can be reduced and which has a minimal number of components. This reverse input shutoff clutch 1 is configured from an input member 2, an output member 3 disposed coaxially with the input member 2, a pressed member 4 having a pressed surface 10, and an engaging element 5. When rotational torque is inputted to the input member 2, the engaging element 5 moves in a direction away from the pressed surface 10 and transmits the rotational torque to the output member 3 on the basis of the engagement with the input member 2, and when rotational torque is reverse-inputted to the output member 3, the engaging element 5 moves in a direction toward the pressed surface 10 and prevents or minimizes relative rotation between the output member 3 and the pressed member 4 on the basis of the engagement with the output member 3.
