A liquid jet head includes head modules each having a nozzle plate with a nozzle orifice and a passage-forming substrate having a pressure-generating chamber. The chamber communicates with the associated nozzle orifice and is pressurized by the pressure generating element so as to eject droplets. A head case is placed at the side of the passage-forming substrate opposite to the nozzle plate and has flow paths for providing a liquid to the pressure-generating chambers. The liquid jet head includes a fixing plate that has openings through which the nozzle orifices are exposed and carries the head modules positioned thereon. A connecting member is connected to the surface of the head module adjacent to the head case and has flow paths which communicate with the pressure-generating chambers. A reinforced portion made of an adhesive filling a clearance is positioned between adjacent head modules fixed to the fixing plate.

In a clutch mechanism 310, in a state where a suction cap 350 reaches a contact position being in contact with a liquid ejecting head, only the rotation of a third gear 300 in one direction is transmitted to a third rotation shaft J3. During at least one of a period in which the suction cap 350 moves from the contact position to a separating position being separated from the liquid ejecting head and a period in which the suction cap 350 moves from the separating position to the contact position, the rotations of the third gear 300 in both directions of one direction and the other direction are transmitted to the third rotation shaft J3.
