PROBLEM TO BE SOLVED: To provide a dynamic vibration absorber for an elevator, which can suppress the vibration of a rope homogeneously in an arbitrary horizontal direction against transverse vibration of the rope.SOLUTION: A dynamic vibration absorber for an elevator comprises: a main rope holding member 1 (or a balance rope holding member 5) for holding a plurality of main ropes R1 (or balance ropes R2) at a position upper (lower) position of at least one of two end portions of a plurality of main rope R1 (or balance ropes R2); a vibration absorption member 2 enveloping the main rope holding member 1 (or the balance rope holding member 5) and supported to be freely displaced in a horizontal direction with respect to the main rope holding member 1 (or the balance rope holding member 5); and at least three elastic bodies connected to the main rope holding member 1 (or the balance rope holding member 5) and the vibration absorption member 2, for applying, when the vibration absorption member 2 is displaced in an arbitrary direction, a restoration in an opposite direction of the one direction. |
