Zusammenfassung:PROBLEM TO BE SOLVED: To provide an elevator having an emergency stopping device for acquiring rail pressing force required for braking in an emergency by a short pulling-up quantity of dampers.SOLUTION: An elevator includes: dampers 9A and 9B each arranged so that an inside pressing surface is opposite to a guide rail 2 and having a pressing force imparting gradient surface 15 formed as a gradient of approaching the guide rail 2 according to proceeding in the pulling-up direction to the anti-guide rail side and a standby gradient surface 16 formed in a position retreated to the guide rail 2 side more than the pressing force imparting gradient surface; an elastic body 7 arranged between an upper frame 5 and a lower frame 6 installed in a lifting body; a plurality of rollers 10A and 10B arranged along the pulling-up direction of the dampers 9A and 9B between the pressing force imparting gradient surfaces 15 of the dampers 9A and 9B and guides 8A and 8B; and a stepped roller 10D positioned in the anti-pulling-up direction more than the rollers, positioned between the standby gradient surfaces 16 of the dampers 9A and 9B and the guides 8A and 8B in a steady state and transferring to contact with the pressing force imparting gradient surfaces 15 in response to the initial movement in emergency pulling-up time of the dampers 9A and 9B.
