An elevator emergency safety device includes: a damper that includes a first sliding surface, and that is pressed against a guide rail to generate a braking force; a movable member that includes a second sliding surface that contacts the first sliding surface; and an elastic body that applies to the first sliding surface a pressing force that presses the damper against the guide rail, wherein: the damper is configured so as to be movable in a vertical direction relative to the movable member by the first and second sliding surfaces sliding; and the elastic body is configured such that the pressing force F1 increases, reaches a maximum value, and then decreases, as a position of a contacting portion between the first and second sliding surfaces moves upward.
