A liquid ejecting device includes first and second housings. The first housing is movable between a proximity position and a separated position with respect to the second housing, and accommodates a liquid ejecting head. The first housing includes a cover attached to the first housing and movable with respect to the head between a protection position for the head and a retreat position, and a movement mechanism which causes the cover to move with the movement of the first housing. The movement mechanism includes a hole formed in the second housing, and an intermediate member including a protrusion movable along the hole with the movement of the cover. In the separated position, the protrusion abuts the hole in both directions in which force to move the cover between the retreat position and the protection position is applied so that the side walls restrict movement of the protrusion.
