A scroll compressor having a reversion preventing device includes: a driving unit inserted in a closed casing and generating a driving force; a compressing unit for compressing and discharging a fluid when the driving unit is driven; a rotational shaft rotatably supported by a main frame and a sub-frame that are fixed at the casing and transmitting the rotational force generated from the driving unit to the compressing unit; and a reversion preventing device installed at one side of the rotational shaft and stopping the rotation of the rotational shaft when the driving unit is rotated in a direction opposite to the direction in which the driving unit compresses the fluid. Since the reversion preventing device is installed at the rotational shaft in order to stop the rotation of the rotational shaft if the rotational shaft is rotated in the reverse direction, blocking the driving unit from being rotated in the reverse direction. Thus, an abnormal vibration and a noise occurrence of the driving unit can be prevented, and thus, a reliability of the compressor can be improved. <IMAGE> |
