PROBLEM TO BE SOLVED: To provide a pressurizing device capable of working a work with a large pressurizing force without enlarging its size. SOLUTION: This device is provided with a base 2, in which a fulcrum O is provided and a lever 4 rockable around the fulcrum O. The lever 4 is provided with a force applying point P provided in a first position apart from the fulcrum O and a point Q of application provided in a second position apart from the fulcrum O shorter than the distance in the first position. A hydraulic cylinder 18, rocking the lever 4 around the fulcrum O by operation, is provided in a force applying point P of the lever 4. A punch 10, approaching to and separating from the base 2 by displacement of the point Q of application based on the operation of the lever 4, is provided in the point of application of the lever 4.
