<P>PROBLEM TO BE SOLVED: To reduce a cost by eliminating a sensor and to reduce a time and labor for maintenance. <P>SOLUTION: This damping device is constituted to displace a guide roller 11 and to make a current flow by a counter electromotive force in a coil 15 of an electromagnetic actuator 17 when vibration is generated in a car. In a control part of the damping device, a car vibration estimating device for detecting a current generated in the electromagnetic actuator 17 by the vibration of the car and estimating the vibration of the car and a command generating device for outputting a command signal to suppress the vibration of the car to the electromagnetic actuator 17 according to information from the vibration estimating device. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
