Abstract

An electromagnetic brake (200) includes a brake plate (202), two pressing members (203a, 203b) that press the brake plate (202) when braking is performed on the brake plate (202), a compression coil spring (208a, 208b) that urges the two pressing members (203a, 203b) in such a manner that the brake plate (202) is pressed, and an electromagnetic coil (207) that moves the two pressing members (203a, 203b) in a direction that is opposite to a direction of an urging force of the compressing coil spring (208a, 208b) when braking is not being performed on the brake plate (202). The compressing coil spring (208a, 208b) urges the two pressing members (203a, 203b) in such a manner that the magnitudes of pressing forces of the two pressing members (203a, 203b) are made to be different from each other.
