Elevator which is characterized in that it basically comprises a reduced-speed motor associated with a shaft fixed by means of a conical piece of flexible material, the core of the motor being connected to the conical piece whilst the latter rotates on the shaft by means of individual screw threads which exist on the respective surfaces of the latter, the assembly having an upward/downward movement related to the direction of revolution of the core of the motor on the shaft by means of the aforesaid conical piece, having a pusher associated with vertical rods by means of a transverse connection piece, and also a breaker compatible with notches which exist close to the ends of the aforesaid rods, thus delimiting the displacements of the assembly and the aforesaid rods and connection piece preventing the rotation of the casing of the motor. <IMAGE>
