Abstract

In a safety device for an elevator, a receiving brake member and a rotatable brake member are disposed in a housing displaceable horizontally with respect to a guide rail. The guide rail is arranged between the receiving brake member and the rotatable brake member. The rotatable brake member is rotatable vertically about a rotating shaft disposed in the housing. The guide rail is grasped between the receiving brake member and the rotatable brake member by vertical rotation about the rotating shaft. The rotatable brake member is provided with a rolling contact portion whose distance from the receiving brake member is continuously smaller even when the rotatable brake member rotates in anyone of upper and lower directions. The rolling contact portion is configured along an outer peripheral surface of one cylinder having an axial line eccentric to a center line of the rotating shaft.
