The invention relates to a decelerating clutch and a washing machine. The decelerating clutch comprises an input shaft, a decelerating device, a clutch device, an output shaft, an output shaft sleeve and a motor, wherein a second bearing is arranged near one end, which penetrates into the decelerating device, of the input shaft, a first bearing is arranged near one end, which penetrates into the decelerating device, of the output shaft sleeve, the decelerating device is arranged between the first bearing and the second bearing, and at least a part of the clutch device is arranged on the periphery of the decelerating device. The decelerating device and at least a part of the clutch device are arranged between the first bearing and the second bearing, so that both ends of the decelerating clutch are respectively supported, and the support reliability of the decelerating clutch is increased; additionally, at least a part of the clutch device is arranged on the periphery of the decelerating device, so that at least a part of projection of the clutch device coincides with that of the decelerating device on the axis of the decelerating clutch, and the integral height of the decelerating clutch is reduced.
