Abstract
In an elevator, guide devices are attached to the elevator and include a guide lever driven in a plane; a guide element attached to the guide lever; a stationary actuator part fixed to a support member; and a moving actuator part fixed to the guide lever, wherein a first part of the moving actuator part and the stationary section is a magnet that generates a magnetic field crossing a driving direction of the moving actuator part, a second part of the moving actuator part and the stationary section is a coil wound around a bobbin which is arranged so that it is influenced by the magnetic field and drives the movable section of the actuator in the driving direction of the movable section of the actuator. The magnetic field is generated by an electric current flowing in the coil when the elevator car is vibrated.
