Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP3906744
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To interrupt surely transmission of power in a predetermined torque.
SOLUTION: When transmitting torque exceeds predetermined torque, a center hub 13 is displaced in a rotational axis direction by contacting a point side of a protrusion 13b with a inclined plane 15 to move the point side of the protrusion 13b along the inclined plane 15. Consequently, when transmitting torque exceeds predetermined torque, the center hub 13 is displaced in the rotational axis direction relatively to a pulley main body 11, so that the bending moment operates to a bridge portion 13d in addition to a pulling force for transmitting torque thereto. Accordingly, when exceeding the predetermined torque the fatigue limit of the bridge portion 13d is largely lowered, so that the bridge portion 13d is surely broken with the predetermined torque.
