In a pressure booster equipped with a switching valve that switches each drive chamber on the outside of both pistons to communicate with an inlet port and an exhaust port, each of the above-mentioned inlet check valves is attached to the closing direction of the valve seat by a check valve spring. The check valve body is provided with a biased check valve body, a protrusion that is slidable relative to the check valve body and whose tip projects into the pressure intensifying chamber, and an auxiliary spring contracted between the check valve body and the protrusion. A pressure booster characterized by:
