Traction sheave elevator has a drive machine (1) and, coupled with it, a traction sheave (3) provided with a rope groove (2), the hoisting rope (4) running over the traction sheave, an elevator car (6) and its counterweight (7) suspended on the hoisting rope and moving in an elevator shaft (6). The elevator uses at least two diverting pulleys (8,9) which causes the hoisting rope going to the traction sheave (3) and the hoisting rope coming from the traction sheave (3) to run crosswise with respect to each other. The diverting pulleys and the traction sheave are placed so that the planes of rotation of the diverting pulleys (8,9) lie on different sides of the plane of rotation of the traction sheave (3).
