<P>PROBLEM TO BE SOLVED: To downsize a linear motor (an electromagnetic actuator) for reducing vibration from a guide device 5 for guiding lifting of an elevator car. <P>SOLUTION: A body part 13 of the linear motor 10 is fixed to a support base 6 fixed to the car, and a first linear guide 32 is arranged between a support part 30 fixed to the support base 6 and a movable part 12 of the linear motor 10. A second linear guide 33 is arranged between an L type rocking piece 25 for rocking (in the C direction) together with rocking of a roller 9 of the guide device 5 and an L type bracket 31 fixed to the movable part 12. Thus, the rocking in the C direction is converted into linear motion in the D direction and the E, F direction. Thus, even if the roller 9 rocks, since an interval between a coil 10c and a magnet 10e is always kept constant, the interval between the coil 10c and the magnet 10e is reduced, and the linear motor 10 can be downsized. <P>COPYRIGHT: (C)2013,JPO&INPIT |
