るチヤツク装置。 An actuator shaft on the central axis of the chuck housing is inserted into the chuck housing from the rear so that it can be advanced and retracted by an external mechanism, and the actuator is provided at the insertion end of the shaft so that it can be integrally moved in the longitudinal direction and in the radial direction of the shaft. On the other hand, chuck claws are provided on the front surface of the chuck housing at equal positions and at equal intervals around the central axis, and a claw shaft in the front and rear direction having each claw is inserted into the chuck housing from the front to create a spherical slide. The chuck device is supported by a bearing, each claw shaft insertion end is supported by the actuator via a spherical sliding bearing so as to be slidable in the front-rear direction, and the sliding surface is inclined in the front-rear direction. A vertical support shaft is supported by one of the actuator and the pawl shaft via a spherical sliding bearing on the insertion end side of the pawl shaft, and a hole is formed in the other side, into which the support shaft is fitted so as to be movable in the front and rear direction. The shaft sliding surface of the hole is the sliding surface of the claw shaft,
A chuck device characterized in that a space is formed between the actuator and the pawl shaft in the axial direction of the support shaft.
