PROBLEM TO BE SOLVED: To provide a link press which can be processed under a high press load and can improve the cycle time of the processing even when a motor of a relatively small output is used, is excellent in controllability, in which an error in the positional relation among constituent parts of a link mechanism is prevented, and the processing precision is easily maintained. SOLUTION: The link press is equipped with the link mechanism 1 for converting a rotary motion to a straight-line motion, and a ram 6 moving up and down with the straight-line motion for press processing. A driving transmission system 14 for transmitting drive from a motor 13 to a crankshaft 3 is disposed. This driving transmission system 14 can controllably driving transmit the up and down motion of the ram 6 by rotational control of the motor 13. The crankshaft 3 and a pivot shaft 12 of a constraint link 8 are disposed in a crankshaft supporting hole and a constraint link supporting hole provided on the same board part 9a in a frame 9, respectively.
