するパワーチヤツク。 A rotary cylinder that connects a chuck and a rotary cylinder with a spindle, supports the shaft at the other end of the rotary cylinder with a rotary joint, and moves forward and backward through the center of the spindle using pressurized oil or air supplied through the rotary joint. In a power chuck which uses a piston rod to open and close a jaw attached to the chuck, the center of the shaft is inserted through the other end of the piston rod of the rotating cylinder, a rod is provided that protrudes from the end face of the rotary joint, and a dog is attached to the end. A power chuck characterized in that a limit switch with which the dog comes into contact beyond the piston stroke necessary for chucking is provided near the end face of the rotary joint, and mischucking is detected by the operation of the limit switch.
