A brake electromagnet (1) has multiple magnetic poles (2) in a rail longitudinal direction and is placed in normal times so that a predetermined interval is provided between the magnetic poles (2) and a rail (4), wherein, at the time of emergency brake operation in an emergency, coils (3) are energized so that polarities of each set of adjacent ones of the multiple magnetic poles (2) are set to the same polarity but an electromagnetic force is generated between totally alternating sets of the polarities, to thereby cause the magnetic poles (2) and the rail (4) to come close to each other; and thereafter, each set of adjacent magnetic poles (2) are changed to have mutually different polarities to thereby control generation of an eddy current. This accomplishes braking with a short time from issue of the operation command for the braking device to generation of the braking force and with a small shock to the passengers.
