Claim:
1. An inkjet recording apparatus comprising: a guide having a vertical flat surface extending in a first direction that is horizontal; a carriage mounting an inkjet recording head configured to reciprocate along the guide in the first direction, wherein the carriage has a contact slide portion sliding on the vertical flat surface with a lubricant; a platen configured to support a sheet to be recorded by the inkjet recording head; a mechanism to change a height of the carriage relative to the platen by moving the carriage in a second direction that is vertical along the vertical flat surface; and a first rib-like structure and a second rib-like structure each formed on the carriage such that the contact slide portion is disposed between the first and the second rib-like structures in the first direction, wherein in each of the first and the second rib-like structures, a plurality of ribs forms a cross-like shape having a size larger than the contact slide potion in the second direction and a center of the cross-like shape in the second direction is rid of ribs, whereby the first and the second rib-like structures gather the lubricant on the vertical flat surface toward the center in the second direction while the carriage reciprocates, wherein a sliding region on the vertical flat surface, in which the contact surface slides while the carriage reciprocates, shifts in the second direction according to changing of the height of the carriage changed by the mechanism.
