A liquid ejecting apparatus, including a head and a capping mechanism which includes: a surrounding member including a lip that surrounds the head and a diaphragm which closes a space between the lip and the head and which outwardly biases the lip; a guide fixed to the head; a holder which surrounds the head and to which the lip is fixed; a moving mechanism configured to move the guide and the holder relative to each other such that the capping mechanism is placed in one of a hermetically sealed state and a non-hermetically sealed state; and a restraining member which is provided on one of the holder and the guide and which is configured to restrain outward deformation of the lip by contacting the other of the holder and the guide, when the capping mechanism is placed in the hermetically sealed state.
