PROBLEM TO BE SOLVED: To solve the problem in which useless liquid consumption at the time of a maintenance operation occurs when suction means common to a plurality of caps is connected. ! SOLUTION: A valve member 120 for opening/closing an opening 214 is arranged in a cap 114. In a case in which the cap 114 caps a nozzle surface 101m, the valve member 120 is lifted up by an arm member 121 and separated from the opening 214, and thereby the opening 214 is opened. In a case in which the cap 114 does not cap the nozzle surface 101m, the opening 214 is closed by the valve member 120 when a liquid does not exist in the cap 114, and the valve member 120 rises up with buoyancy and thereby the opening 214 is opened when the liquid exists in the cap 114. !
