Disclosed herein is a clutch device for washing machines. The clutch device comprises a washing shaft for transmitting a rotating force to a pulsator, a dewatering shaft disposed along the outer circumference of the washing shaft in a coaxial fashion for transmitting the rotating force to a washing tub, and a spiral spring, having one end fixedly connected to the washing shaft and the other end fixedly connected to the dewatering shaft, for transmitting the rotating force from the washing shaft to the dewatering shaft when the spiral spring comes into tight contact with the washing shaft or the dewatering shaft as the washing shaft is rotated. Consequently, the present invention has the effect of simplifying the overall structure of the clutch device. The clutch device further comprises a friction member attached to the washing shaft or the dewatering shaft for generating a frictional force when the spiral spring is extended or compressed. Consequently, the present invention has the effect of decreasing wear of the washing shaft and dewatering shaft, with which the spiral spring is in tight contact, and of improving efficiency of rotating force transmission.
