PROBLEM TO BE SOLVED: To provide an automatic specific pressure loading slide valve for targeting the improvement of the specific pressure loading force and a compactness of the shape by using a cum surface and a shifting body to slide a seal case on a three-layer constituted slide valve. SOLUTION: The automatic specific pressure loading slide valve apparatus is the three-layer constituted slide valve and the shifting body of the seal case 21 can be slid on the supporting surface of the spring-holder, and the apparatus is constituted of the performance to the loading and the release of the specific pressure, while sliding with an actuator 7 by a connecting the slide case and the seal case 21 with a connecting means 23 or a connecting stopper.
