Abstract
A cam roller is engaged with a first engaged surface facing downward in a lifting and lowering direction of a cap and moves so as to follow the rotation trajectory about a shaft in the upward direction approaching a liquid ejecting head and in the downward direction separating from the liquid ejecting head. In addition, in the lifting and lowering direction of the cap, the cam roller is engaged from above with a second engaged surface which faces upward at a position lower than the first engaged surface and the first engaged surface has a plane portion as a non-overlapped area which does not overlap the second engaged surface in a direction perpendicular to both of the lifting and lowering direction and the direction of the shaft in a range that the cam roller follows the rotation trajectory about the shaft.
