PROBLEM TO BE SOLVED: To improve a coiler device so that the coiler device has looseness caused by gravity as small as possible. SOLUTION: In the coiler device for bar-shaped rolling materials provided with a hollow shaft 8, a coiler tube holder 9 and the coiler tube 10 for bar- shaped rolling materials, the hollow shaft is supported rotatably around the axial line 5 by at least an assistant bearing 11 and a main bearing 12 and, at this time, the sub bearing and the main bearing are separated from each other at a certain distance in the axial direction and the coiler tube holder 9 is joined to the hollow shaft so as not to rotate, projected beyond the main bearing and with which the coiler tube is supported. Now, the coiler tube has an inlet end 21 and an outlet end 22, the inlet end is situated concentrically with the axial line and the outlet end 22 at a certain distance in the radial direction from the axial line, and the coiler tube holder 9 consists of, at least partially, a material having smaller density than steel.
