PROBLEM TO BE SOLVED: To provide a pressing device where the temperature of lubricating oil flowing through a column part is fixedly held, and the variation in the displacement of heat in the column part in accordance with press working conditions or the like can be suppressed. SOLUTION: The pressing device is provided with: a lubricating oil storage means 22; a lubricating oil flow passage 24 formed at the inside of a column part 8; a first lubricating oil circulation means 28 for circulating lubricating oil through a crown part 6; and a second lubricating oil circulation means 28 for circulating the lubricating oil through the column part 8. The first lubricating oil circulation mean 26 comprises: a first feed line 48 for feeding lubricating oil to a crankshaft 10; and a first return line 50 for returning the lubricating oil from the crankshaft 10 to the lubricating oil storage means 22, and the second lubricating oil circulation means 28 comprises: a second feed line 58 for feeding the lubricating oil to the lubricating oil flow passage 24; and a second return line 60 for returning the lubricating oil from the lubricating oil flow passage 24 to the lubricating oil storage means 22.
