Abstract: A carriage includes a base plate, a liquid jet head which includes a support plate attached to the base plate, a first engagement portion which is formed on one end in a Y direction of the support plate, and a fixing tool for positioning the support plate with respect to the base plate, the fixing tool being slidable in an X direction with respect to the base plate and engaged with the first engagement portion. The fixing tool allows movement in the Y direction of the first engagement portion with respect to the fixing tool, and restricts movement in the X direction of the first engagement portion and movement in the thickness direction of the base plate of the first engagement portion with respect to the fixing tool.

Abstract: There are provided a liquid jet head and a liquid jet recording device each capable of obtaining a stable ejection performance. An inkjet head includes a head chip provided with a plurality of ejection channels sequentially arranged from a +X direction toward a −X direction in an X direction, and configured to jet ink located inside the ejection channels, a flow channel member which is provided with a guide flow channel for guiding the ink from the +X direction toward the −X direction in the X direction, and in which the guide flow channel is coupled to each of the ejection channels, and a board unit on which a plurality of drive ICs arranged along the X direction is mounted, and which is thermally coupled to the flow channel member, wherein the flow channel member is provided with a cooling flow channel which guides the ink from the −X direction toward the +X direction in the X direction so as to cool the plurality of drive ICs.

Abstract: A carriage includes: a base plate; a liquid jet head including a support plate attached to the base plate; a first engagement portion formed on one end in a Y direction of the support plate; a fixing tool for positioning and fixing the support plate with respect to the base plate, the fixing tool being fixed to the base plate slidably in an X direction by screws and engaged with the first engagement portion; and a flat spring portion that presses the fixing tool toward the base plate. The fixing tool allows movement in the Y direction of the first engagement portion with respect to the fixing tool, and restricts movement in the X direction of the first engagement portion and movement in a thickness direction of the base plate of the first engagement portion with respect to the fixing tool.
