Claim:
An ink jet recording apparatus that prints using an ink jet head, the apparatus comprising: a main recording apparatus body that includes the ink jet head and an apparatus case that houses the ink jet head; an ink tank unit, including an ink tank, that includes a case that is separate from the apparatus case, the ink tank being located within the case of the ink tank unit, such that the ink tank unit and the ink tank are provided separate from the main recording apparatus body; an ink tube, connected to the ink jet head and the ink tank, that supplies ink from the ink tank to the ink jet head; and a tube support member, having a bent-shape surface that makes contact with the ink tube, that, when the ink tube is pulled, causes friction to arise between the bent-shape surfaces and the ink tube, the friction working against the pulling force in order to suppress the ink tube from moving in an extension direction of the ink tube, the ink tube being regulated by a first regulation portion located on the ink tank unit and a second regulation portion located on a portion of the tube support member, the first and second regulation portions regulating the extension direction of the ink tube within a predetermined angular range, the bent-shape surface that make contact with the ink tube being formed so as to correspond to the predetermined angular range.
