Coating tool

A roller fixed coating tool comprising

• an application roller having a concave to receive a bearing cap on both ends, and
• a grip joined with a first frame having a protruding support shaft to support one end of the application roller and a second frame having a protruding support shaft to support the other end of the application roller, which comprises a sliding mechanism set on at least one connection between the frames and the grip to enlarge or shorten a distance between the two support shafts,
• the support shafts of the aforementioned first frame and the second frame each having, on a tip thereof, a rotatable bearing cap, the bearing cap having two or more concaves for preventing rotation of the roller, at about the same intervals on a circumference of a circle concentric with the axis of the support shaft, which circle being defined on an opposite end of the bearing cap from the side where it is fitted into a concave on the end of the application roller, and said first frame and the second frame each having a pin whose tip is to be inserted into said concave for preventing rotation of the roller,
• wherein the application roller is rotatably supported by sliding at least one of said first frame and the second frame and fitting the bearing cap on the tip of both support shafts into the concaves on both ends of the application roller, and
• wherein the application roller is non-rotatably supported at predetermined positions about the axis upon rotation of the rotatable application roller about the axis to insert the tip of said pin into one desired concave of the two or more concaves formed on each bearing cap on both ends for preventing rotation of the roller.
