Liquid jetting apparatus

A liquid jetting apparatus configured to jet liquid toward a recording medium, comprising:

• a liquid jetting head including a liquid jetting surface and a plurality of nozzles arranged in the liquid jetting surface;
• a cap including a first cap and a second cap which are arranged side by side in a first direction parallel to the liquid jetting surface, the first cap including a first lip portion that is contactable with the liquid jetting head and is configured to surround a part of the plurality of nozzles in a case that the first lip portion is in contact with the liquid jetting head, the second cap including a second lip portion that is contactable with the liquid jetting head and is configured to surround other part of the plurality of nozzles in a case that the second lip portion is in contact with the liquid jetting head;
• a cap switching device configured to move the cap relative to the liquid jetting head in a second direction perpendicular to the liquid jetting surface and to perform switching between a capping state and an uncapping state, the capping state being a state in which the first and second lip portions of the cap is in contact with the liquid jetting head to such that the cap covers the plurality of nozzles, and the uncapping state being a state in which the first and second lip portions of the cap is separated away from the liquid jetting head;
• a first protrusion of which tip end is located, in the capping state, further away from the cap than the liquid jetting surface in Hall the second direction perpendicular to the liquid jetting surface;
• and
• a second protrusion of which tip end is located, in the capping state, further away from the cap than the nozzle surface in the second direction;
• wherein a gap between the first lip portion of the first cap and the second lip portion of the second cap in the first direction is located between the first protrusion and the second protrusion in the first direction, and
• wherein a center of a first area of the cap in a third direction parallel to the liquid jetting surface and orthogonal to the first direction and a center of a second area of the cap in the third direction are located between the first protrusion and the second protrusion in the third direction, the first area of the cap being an area surrounded by the first lip portion of the cap, and the second area of the cap being an area surrounded by the second lip portion of the cap, the third direction being parallel to a conveyance direction of the recording medium.
