To provide a double-deck elevator that can suppress the shortening of the lifetime of electronic components as compared with the prior arts as a safety measure in the event of a failure on the auxiliary drive side.SOLUTION: Included are: a car interval control device 80 that controls the operation of the brake device 48 that applies a braking force to the motor 42 that drives the car interval adjusting mechanism that adjusts the car interval between the upper car and the lower car. The car interval control device 80 includes a car safety circuit 86 with door open detection switches 60 and 62 connected in series, a bypass circuit 88 including contacts 88a, 90a which are safety switches connected in parallel with the door open detection switches 60, 62, and a brake release switch 100 provided in the electric circuit between the car safety circuit 86 and the brake device 48. When the door open detection switches 60 and 62 detect a door open state, the contacts 88a and 90a of the bypass circuit 88 are turned off and the car safety circuit 86 is shut off when the brake release switch 100 is turned on.SELECTED DRAWING: Figure 3

    【課題】副駆動装置側に故障が生じた場合における安全策において、従来よりも、電子部品の寿命短縮を抑制できるダブルデッキエレベータを提供する。【解決手段】上かごと下かごの間のかご間隔を調整するかご間隔調整機構を駆動するモータ42に対する制動力を作用させるブレーキ装置48の作動を制御するかご間隔制御装置80を有する。かご間隔制御装置80は、戸開検知スイッチ60,62が直列に接続されたかご安全回路86、戸開検知スイッチ60,62と並列に接続された安全スイッチである接点88a,90aを含むバイパス回路88、かご安全回路86とブレーキ装置48との間の電路に設けられたブレーキ開放スイッチ100を含む。戸開検知スイッチ60,62が戸開状態を検知しているとき、ブレーキ開放スイッチ100がオンされると、バイパス回路88の接点88a,90aがオフされて、かご安全回路86を遮断する構成とする。【選択図】図3
