A pressurizing device, comprising a fixed part, an input shaft allowed to direct-act axially relative to the fixed part, an output shaft extending coaxially with the input shaft and slidable relative to the fixed part and the input shaft, a direct-coupling mechanism allowing the output shaft to be direct-coupled with the input shaft and the input shaft to direct-act relative to the fixed part so as to rapidly feed the output shaft relative to the fixed part, a fluid pressure mechanism allowing the input shaft and the output shaft to be coupled with each other through a fluid and the input shaft to direct-act relative to the output shaft so as to increase the energization of the input shaft by the Pascal's principle and transmit the increased energization to the output shaft, and a control mechanism operated by the energization given from the input shaft and controlling the fluid coupling of the input shaft with the output shaft.
