Title:
REVERSE INPUT BLOCK CLUTCH
Document Type and Number:
Japanese Patent JP2020008124
Kind Code:
A
Abstract:
To provide a reverse input block clutch which is reducible in axial dimension and suppressed in the number of part items, and can stably idle an output member when rotation torque is reversely inputted.SOLUTION: A reverse input block clutch 1 is constituted of an input member 2, an output member 3 arranged coaxially with the input member 2, a pair of engagement pieces 4, and a spring 5 for imparting a force in a tensile direction so as to approach a pair of the engagement pieces 4. When rotation torque is inputted to the input member 2, the pair of the engagement pieces 4 move in a direction in which they separate from each other on the basis of engagement with the input member 2, and transmits the rotation torque to the output member 3, however, when the rotation torque is inputted to the output member 3, the output member 3 is made to idle on the basis of a clearance 16 between a pressed face 13 of the output member 3 which is formed of the elasticity of the spring 5 and pressing faces 14 of the engagement pieces 4, and the rotation torque which is reversely inputted to the output member 3 is prevented from being transmitted to the input member 2.SELECTED DRAWING: Figure 1
