The invention discloses a traction device for an elevator. The traction device comprises a tractor, a guide wheel, a counterweight block, a car, a counterweight diversion sheave, a car diversion sheave, a steel wire rope and a rope pressing wheel, wherein the top of the counterweight block is connected with the counterweight diversion sheave through the steel wire rope; one end of the steel wire rope is fixed; after the steel wire rope is vertically downwards threaded through the counterweight diversion sheave, vertically upwards threaded through a traction wheel of the tractor, threaded through the rope pressing wheel and the guide wheel in sequence and vertically downwards threaded through the car diversion sheave, the steel wire rope is fixed; and the top of the car is connected with the car diversion sheave through the steel wire rope. The traction wheel of the tractor is above the horizontal plane of the guide wheel; the added rope pressing wheel enables a traction wrap angle to be increased to 180 degrees; the traction transmission is realized through enough frictional force; and the traction rope is prevented from slipping on the traction wheel when a no-load car upwards moves to an upper limit position and brakes urgently.
