<p>The present invention relates to a power cut-off apparatus of a clutchless compressor, which comprises: a pulley unit axially rotated by receiving power from an external driving source through a belt; a driving hub transmitting the power of the pulley unit; a driven hub installed on the same axis of the driving hub, and able to be axially rotated integrally with the driving shaft of the compressor; and a power cut-off part with a fracture part coupled to be fixed to one sides of the driving hub and the driven hub by fixing units, transmitting the power from the driving hub to the driven hub, and fractured depending on the amount of torque applied to the driven hub. According to the present invention, because capable of making the distribution of fracture torque small, the power cut-off apparatus is capable of being operated in the case of only sticking in the compressor, is capable of preventing power from being cut off by malfunction due to the overpower of an engine, and is capable of improving durability against distortion.</p> |
