The invention relates to a washing machine deceleration clutch comprising an input shaft, a deceleration device, a clutch device, an output shaft and an output shaft sleeve. The deceleration apparatus comprises at least a central gear, a transmission gear, a transmission gear rack and an internal gear ring; the clutch device comprises at least one clutch shaft sleeve and a driving device driving the clutch shaft sleeve to axially move; the clutch shaft sleeve is arranged on the circumferential periphery of the deceleration device; the clutch shaft sleeve and the transmission gear rack can axially slide to each other, but cannot be circumferentially rotationally connected; the internal gear ring is connected with the output shaft sleeve; the clutch shaft sleeve axially moves to control different output states of the output shaft and the output shaft sleeve. The overall height of the deceleration clutch can be reduced, so washing machine size can be reduced with the same of the washing capacity or washing capacity can be increased with the same of the washing machine size.
