Japanese Patent JP2015054754
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an elevator device capable of suppressing transmission of displacement with a simple configuration when an excessive load is applied on a rail from a building side at the time of earthquakes.SOLUTION: As a rail support device which connects a rail side rail bracket 2 and a building side rail bracket 4, there are provided disc springs 3a, 3b which relatively hold position of the rail side rail bracket 2 and the building side rail bracket 4 by friction force, and a connection structure with a play which, by allowing a displacement which overcomes the friction force of the building side rail bracket 4 when earthquake occurs within a range of play, suppresses transmission of displacement from a building 7 side to a rail 1 side.
