Abstract
Provided are a liquid ejection apparatus and a maintenance apparatus capable of suppressing unintended movement of a wiping unit. The maintenance apparatus includes: a wiping unit configured to wipe the ejection opening surface of a liquid ejection head in which ejection openings over a length corresponding to the width of a print medium are formed; and a lock member configured to restrict movement of the wiping unit from a position to which the wiping unit is evacuated from the ejection opening surface.
