Claims

[Claims for Utility Model Registration] A fixed base; A movable table provided above the fixed base so as to be movable and rotatable in a horizontal plane; A workpiece fixed on the movable table and operated by fluid pressure. and a fluid connector that is placed on the movable table and supplies fluid in a distributed state to the workpiece fixing clamp, which is fixed on the movable table and supplies working fluid to the workpiece fixing clamp. A fluid connection device comprising: a cylinder to which a supply pipe is connected; and a central member rotatably inserted into the cylinder and connected to a connection pipe from a fluid supply source; and fixed to the fixed base. 1. A machine tool having a clamp for fixing a workpiece, further comprising: a parallel movement mechanism that supports the center member so as to lock relative rotation of the center member with respect to the fixing base.
