To provide a forming oil coating device capable of improving the environment of a working site and the utilization efficiency of a forming oil.

A brush 101 constituting a forming oil coating member is fixed by using a fixing piece 109 and a bolt 117 so as to be turnable around the cylindrical axis of a brush-equipped pipe 113, and each brush-equipped pipe (113-116) is supported by a plate P3 or a plate receiving member 209 so as to be turnable around its axis. The brush 101 is formed by bundling numerous nylon-based fibers, and a supporting plate 105 is fixed between the fixing piece 109 and the brush 101. The supporting plate 105 is provided long in the y-axis direction so as to excellently maintain the shape of the brush 101, to excellently ensure the abutting pressure on a metal plate W of the brush 101, and excellently ensure the positioning accuracy of the brush 101 with respect to the metal plate W. Substantially columnar oil-dripping holes 121a, 122a are formed at lowest points of oil receipt pipes 121, 122.
