The invention provides an elevator speed reducer which comprises a box body, a first motor, a clutch, chain wheels and a chain; the first motor is arranged outside the box body, an output shaft of the first motor extends into the box body to be connected with one end of the clutch, and the other end of the clutch is connected with the input end of a speed reducing transmission device; and the output end of the speed reducing transmission device is connected with one end of a synchronous chain, the other end of the synchronous chain extends to the lower portion of the box body and is connected with an elevator car, the clutch can be a claw clutch, the speed reducing transmission device drives the elevator car to move after first-stage speed reduction transmission, second-stage speed reduction transmission and third-stage speed reduction transmission, and a brake is arranged on an output shaft of the speed reducer. In addition, the overall shape of a reduction gearbox body can be arranged according to the power space position of the reduction gearbox body, and the exterior shape can be a vertical shape, a horizontal shape or a special-shaped shape. The elevator speed reducer is simple in structure, small in occupied space, low in cost, high in transmission efficiency, good in reliability and low in operation noise.
