A pressurizing apparatus includes a fixed portion, an input shaft acting directly in an axial direction with respect to the fixed portion, an output shaft extending coaxially with the input shaft to slide with respect to the fixed portion and the input shaft, a direct-connecting mechanism directly connecting the output shaft and the input shaft and causing the input shaft to directly act with respect to the fixed portion to thereby rapidly carry the output shaft with respect to the fixed portion, a fluid pressure mechanism connecting the input shaft and the output shaft in a fluid manner and causing the input shaft to directly act with respect to the output shaft to thereby increase biasing of the input shaft by Pascal's law and transmit the biasing to the output shaft, and a control mechanism actuated by biasing applied by the input shaft to control fluid connection of the input shaft and the output shaft to each other. The control mechanism is directly actuated by biasing of the input shaft applied by the input shaft. Therefore, the apparatus need not include a special actuator for driving the control mechanism and can be formed with a simple structure and at low cost.
