PROBLEM TO BE SOLVED: To provide a gate valve which prevents a slide table from wobbling when receiving an external force and enables a valve member to tightly seal a valve opening when a revolving arm is positioned in a second lock position.SOLUTION: A gate valve includes: a body 10; a driver 20; a slide table 30; a revolving arm 40; and a valve member 50. The body 10 has a first end and a second end. The driver 20 is provided in the body 10. The slide table 30 is provided so as to slide in the body 10 and provided with a driving slide groove 31 which is arranged along a lateral direction and has a nonlinear driving locus. One end of the revolving arm 40 is connected to the driver 20, and the other end is provided in the driving slide groove 31. The driver 20 enables the revolving arm 40 to rotate along the driving locus between a first lock position and a second lock position.SELECTED DRAWING: Figure 2 |
