Claim:
A liquid droplet jetting apparatus which jets liquid droplets, the apparatus comprising: a liquid droplet jetting head which has a jetting surface in which a plurality of nozzles for jetting the liquid droplets are formed; a carriage on which the liquid droplet jetting head is installed and which reciprocatingly moves in a first direction along a surface parallel to the jetting surface; and a guide member which has a guide surface perpendicular to the jetting surface and extending in the first direction and which guides the carriage along the guide surface, wherein the carriage is provided with a fixed slide member which is fixed to the carriage and slides along the guide surface, a movable slide member which is arranged apart from the fixed slide member in the first direction and slides along the guide surface and configured to be movable with respect to the carriage in a second direction perpendicular to the first direction, and an angle change mechanism for changing an angle of the carriage with respect to the first direction by moving the movable slide member in the second direction and adjusting a positional relationship between the fixed slide member and the movable slide member, the angle change mechanism has an inner eccentric cam and an outer eccentric cam rotatable around a rotation shaft extending in an extending direction perpendicular to the second direction, and a rotation stop member intervening between the inner eccentric cam and the outer eccentric cam to prevent one of the inner eccentric cam and the outer eccentric cam from being rotated along with a rotation of the other of the inner eccentric cam and the outer eccentric cam, and the inner eccentric cam is nested inside the outer eccentric cam.
