The invention provides a door device of an elevator and a door anti-falling piece. The door device and the door anti-falling piece can more reliably restrain a door plate from being separated from a sill groove through a simple structure. The retaining body (28) has a mounting portion (28a), an insertion portion (28b), and a plurality of protrusions (28c). The insertion section (28b) protrudes downward from the lower end of the door panel (23) and is inserted into the sill groove (25a). Each protruding part (28c) protrudes from the insertion part (28b) toward the second wall surface (25c). Each of the protrusions (28c) is pressed against the second wall surface (25c) to engage the second wall surface (25c), thereby plastically deforming the second wall surface (25c).

    本公开提供一种电梯的门装置及门防脱件,其能够通过简单的结构更可靠地抑制门板从地坎槽脱离。防脱主体(28)具有安装部(28a)、插入部(28b)以及多个突起部(28c)。插入部(28b)从门板(23)的下端向下方突出并插入于地坎槽(25a)。各突起部(28c)从插入部(28b)朝向第二壁面(25c)突出。各突起部(28c)通过被按压到第二壁面(25c)而咬入第二壁面(25c),使第二壁面(25c)塑性变形。
