The invention provides an observation elevator without a machine room. The observation elevator without the machine room comprises a shaft, an elevator car, an elevator frame arranged outside the elevator car, an elevator bottom rope sheave beam, a guide rail, load-bearing beams, a traction machine, a counterweight, a counterweight diversion sheave and a counterweight side rope end device, wherein the elevator bottom rope sheave beam is arranged at the bottom of the elevator car, two diversion sheaves are further arranged on the elevator bottom rope sheave beam, and installed on the elevator bottom rope sheave beam through a diversion sheave shaft perpendicular to the elevator bottom rope sheave beam, and the elevator bottom rope sheave beam is arranged at the bottom of the elevator car in a mode that an acute angle is formed between the center line of the elevator bottom rope sheave beam and the center line of the guide rail fixedly arranged in the shaft; the traction machine and the counterweight side rope end device are fixed to the load-bearing beams on the upper portion of the elevator frame, a declination angle is kept between the projection shadow, on the horizontal plane, of the center line of a traction machine wheel of the traction machine and the projection shadow, on the same horizontal plane, of the center line of the elevator bottom rope sheave beam, and the counterweight and the counterweight diversion sheave are arranged on the left or right side of the elevator car. The observation elevator without the machine room has the advantages that the size of the shaft of the elevator without the machine room is reduced, the structure is more compact, the utilization ratio of the shaft is increased, and the civil engineering cost is saved.
