An ink jet recording apparatus having a recording head for ejecting ink, a carriage for carrying the recording head, and a mechanism for adjusting a gap between a recording medium disposed on a platen and the recording head, and a gap adjusting method for adjusting a gap between a recording medium disposed on a platen and a recording head. Bearings attached to the carriage and mounted on a guide shaft are displaceable with respect to the carriage, and the bores of the bearings are eccentric with respect to the guide shaft. This enables the carriage to be displaced in a horizontal plane in accordance with the thickness of recording paper, and to consequently incline the ejection-outlet-array line of the recording head on the carriage. Further, the carriage is pivoted about one of the bearings in a plane including the bearings in accordance with the thickness of the paper.
