摘要： The present invention prevents cracking of a brake shoe even when the sliding surface of the brake shoe is heated to a high temperature and provides high reliability. The present invention provides a brake shoe for elevator emergency stop which generates a braking force by pressing brake shoes against a guide rail and making the brake shoes 5 slide to stop an elevator cage in the event of anomalies, including the brake shoes made of a cast iron material having a plurality of grooves 3 formed in a direction substantially perpendicular to the guide rail and gear teeth which constitute a sliding surface with the brake shoes 5 formed as gaps between the grooves, wherein the depth of the grooves is 3 mm or more and not more than 1.7 times the width of the gear teeth.
