<P>PROBLEM TO BE SOLVED: To provide an interlocking device for an elevator landing door, capable of reducing a force required for closing a landing door by reducing a slide resistance generated between an interlocking lever and a hook when the landing door is closed. Ž<P>SOLUTION: The interlocking lever 20 of the interlocking device includes a rotation roller 24 at a rocking end. Thereby, when the landing door is closed, since the rotation roller 24 smoothly rolls on the guide slant surface 12b of an engagement part 12 of the hook 10, the force required for closing the landing door can be reduced. When the landing door is unreasonably opened, the landing door is non-releasably locked at a closure position since the rotation roller 24 is engaged with the engagement part 12.
