Guide for elevator

A guide device for an elevator, which is engaged with a pair of guide rails each having first and second guide surfaces for guiding a car in a car depth direction and a third guide surface for guiding said car in a car width direction and which is adapted to guide a traveling of said car, said guide device comprising:

• a plurality of guide members mounted in said car and abutting said first through third guide surfaces;
• a plurality of urging means provided between said car and said guide members and adapted to press said guide members against said guide rails;
• a plurality of actuators mounted in said car and adapted to adjust a force with which said guide members are pressed against said guide rails;
• a plurality of acceleration sensors mounted in said car and adapted to detect accelerations in the depth direction and the width direction of said car;
• and
• a plurality of controllers for respectively controlling pairs of actuators reversing the force applied to said guide members in accordance with information from said acceleration sensors,
• wherein each controller has:
• a signal processing circuit for receiving detection signals from one of said acceleration sensors and adapted to perform computation processing for restraining any acceleration generated in said car;
• a current amplification device for amplifying/adjusting signals from said signal processing circuit;
• and
• a plurality of diodes respectively provided between said current amplification devices and one of said pairs of actuators and adapted to selectively output signals from said current amplification device to said pair of actuators.
