<P>PROBLEM TO BE SOLVED: To prevent the co-rotation of an input rotation member to reverse input torque applied after the transmission of the input torque, in a reverse input blocking clutch for transmitting only input torque in one direction. <P>SOLUTION: A spring clutch is used as a locking means for engaging (locking) an input gear 1 and an output rotation member 4 with each other so that torque can be transmitted in a specific direction. A one-way clutch 8, allowing the flywheel 6 to run idle in a specific direction and to stop the rotation of the same in the reverse direction by causing the same to engage with the stationary ring 7, is installed between a flywheel 6 and a stationary ring 7 which are elastically connected to the input gear 1 by a coiled spring 5 of the spring clutch. Thus, when the supply of input torque in the specific direction is stopped, the flywheel 6 rotates by inertia to unlock the lock state between the input gear 1 and the output rotation member 4, and then stops after slightly rotating in the reverse direction by the elastic restoration of the coiled spring 5. As a result, the unlocked state is maintained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
