Abstract:
PROBLEM TO BE SOLVED: To provide an elevator device which unfailingly inhibits resonance vertical vibration occurring in a hoist by a simple structure without influencing primary vibration control performance of a vibration control mechanism.SOLUTION: An elevator device 1 includes: a main vibration control mechanism 24 which inhibits propagation of vibration of a hoist 4 to a building; and a vertical vibration control mechanism 30 which inhibits resonance vertical vibration occurring in at least the hoist 4. The vertical vibration control mechanism 30 includes: a leg part 23 in which an upper end is fixed to a lower part of a machine beam 17 and a lower end is fixed to a base 26; a bracket material 30a in which one end is connected to the leg part 23 and the other end is fixed to the base 26; and vibration control rubber 30c disposed between one end of the bracket material 30a and the leg part 23.SELECTED DRAWING: Figure 2
