The invention provides a rear-counterweight villa elevator device without a machine room. The device comprises a car, a tractor, a traction rope, a counterweight body, a counterweight diversion sheave and two bottom diversion sheaves; the tractor is fixed on the top part of an elevator shaft; the counterweight diversion sheave is connected with the counterweight body to form an elevator counterweight unit which is positioned at the rear side of the car; a traction wheel is directly connected with the counterweight diversion sheave through the traction rope; the bottom diversion sheaves are fixed to the bottom part of the car and are respectively close to the front and back diagonal angles at the bottom of the car; an included angle is formed between a connecting line of the two bottom diversion sheaves and a central line of the car; the two bottom diversion sheaves are connected with the traction wheel through the traction rope. The device has the beneficial effects that the width of the elevator car can be ensured in case of insufficient elevator shaft width, and thus the comfort of using can be avoided being influenced by excessively small car width.
