The purpose of the present disclosure is to provide an up-opening door device for an elevator, which can partially open a landing entrance/exit. The transmission shaft (31) is movable in the axial direction of the transmission shaft (31) between a normal position and a separated position. Furthermore, when the transmission shaft (31) is in the normal position, the movable coupling body (33) is inserted into the coupling groove (31a), whereby the attachment state of the low-speed-side sprocket (18) with respect to the transmission shaft (31) becomes a coupled state. Furthermore, when the transmission shaft (31) moves to the separated position, the movable coupling body (33) is brought into contact with the transmission shaft (31) on the outside of the coupling groove (31a) against the coupling spring (34), and the attached state of the low-speed sprocket (18) with respect to the transmission shaft (31) is an independent rotation state.

    本公开的目的在于得到一种电梯的上开式门装置,其能够局部地打开层站出入口。传递轴(31)能够在通常位置与分离位置之间沿传递轴(31)的轴向移动。而且,在传递轴(31)位于通常位置时,可动结合体(33)插入于结合槽(31a),由此低速侧链轮(18)相对于传递轴(31)的安装状态成为结合状态。另外,当传递轴(31)移动到分离位置时,可动结合体(33)抵抗结合弹簧(34)而成为在结合槽(31a)的外侧与传递轴(31)接触的状态,低速侧链轮(18)相对于传递轴(31)的安装状态成为独立旋转状态。
