PROBLEM TO BE SOLVED: To provide a bookbinding pressing device for automatically bookbinding with hydraulic devices. SOLUTION: This pressing device is equipped with an outer frame 1 formed into a near square annular shape, a top mold pressing bar 2, with which papers conveyed to an annular inside are pressed from above so as to temporarily bond by pressure one by one, a bottom mold pressing bar 3, which is opposite to the top mold pressing bar 2 so as to be pressed from below in order to be regularly bond by pressure, an upper pressing mechanism 4 for pressing the top mold pressing bar 2 downwards with hydraulic driving means 8, an upper pulling-up mechanism 5 for pulling-up the lowered top mold pressing bar 2, a lower pressing mechanism 6 for pressing the bottom mold pressing bar 3 upwards with a hydraulic driving means 9, lower pulling-up mechanisms 7 for pulling-down the lifted bottom mold pressing bar 3 for automatic bookbinding.
