PROBLEM TO BE SOLVED: To push a slide plate to a valve casing with a predetermined or more pushing force for a long time.SOLUTION: A slide valve includes: a valve casing 41 formed with a casing opening 44; a slide plate 60 formed with a plate opening 64 and capable of moving to displace between an open state, wherein the casing opening and the plate opening are communicated with each other, and a closed state, wherein the casing opening is closed, in contact with an inner surface of the valve casing 41; and a pushing mechanism 70 for pushing the slide plate to the valve casing. The pushing mechanism 70 includes: a pushing pad 81 formed with a pushing surface 82 widened into a direction wherein the slide plate moves; and a coil spring 75 for pushing the pushing pad 81 to the slide plate 60 on a contact side S, on which the pushing surface 82 of the pushing pad is brought into contact with the slide plate and the slide plate is brought into contact with the inner surface of the valve casing. |
