PROBLEM TO BE SOLVED: To reduce a fall in liquid jet precision resulting from a fall in precision of the interval or attitude of a head unit for the liquid jet surface of a material to be jetted especially in a liquid jet apparatus free from head adjustment. SOLUTION: Under the state that a carriage 62 and a recording head 63 are attached in relation with each other, the first and second portions 632 and 633 of the recording head 63 to be supported abut against the outer circumferential surface of a guide shaft 61. Two pressing members 66 press the guide shaft 61 against the first and second portions 632 and 633 to be supported by the spring force of a leaf spring 67. The first and second portions 632 and 633 to be supported slide directly on the outer circumferential surface of the guide shaft 61 and the recording head 63 comes ready to reciprocate in the reciprocating direction X. The recording head 63 gets supported directly by the guide shaft 61 reciprocally in the reciprocating direction X. COPYRIGHT: (C)2009,JPO&INPIT
