To provide a top-opening type door device of an elevator capable of partially opening a landing entrance.SOLUTION: A transmission shaft 31 can be moved in the axial direction of the transmission shaft 31 between a normal position and a detachment position. An attached state of a low-speed side sprocket 18 relative to the transmission shaft 31 becomes a connection state by inserting a movable connecting body 33 into a connected groove 31a when the transmission shaft 31 is in the normal position. The movable connecting body 33 is brought into contact with the transmission shaft 31 on the outside of the connected groove 31a against a connection spring 34 as the transmission shaft 31 moves to the detachment position, and the attached state of the low-speed side sprocket 18 relative to the transmission shaft 31 becomes an independent rotation state.SELECTED DRAWING: Figure 5

    【課題】乗場出入口を部分的に開放することができるエレベータの上開き式ドア装置を得ることを目的とする。【解決手段】伝達軸31は、通常位置と切り離し位置との間で、伝達軸31の軸方向へ移動可能になっている。そして、伝達軸31が通常位置に位置するとき、可動結合体33が結合溝31aに挿入されていることにより、伝達軸31に対する低速側スプロケット18の取付状態が結合状態となる。また、伝達軸31が切り離し位置に移動すると、結合ばね34に抗して、可動結合体33が結合溝31aの外側で伝達軸31に接する状態となり、伝達軸31に対する低速側スプロケット18の取付状態が独立回転状態となる。【選択図】図5
