A rotary chuck device for gripping a screw auger, which is attached to an auger rotation drive device movably mounted on a guide frame of a horizontal hole drilling device installed in a vertical hole, for rotating the auger. A cylindrical block with a plurality of radial grooves is attached to the front surface of a rotating cylindrical body rotated by a motor, a sliding block is fitted into each groove, and chuck claws are provided on the front surface of each sliding block. A conical block is mounted in the rotating cylindrical body so as to be slid back and forth by a chuck claw opening/closing cylinder, and the inner end of the sliding block is engaged with a plurality of inclined grooves formed on the circumferential surface of the conical block. 1. A rotary chuck device having a cover, characterized in that the joint portions are slidably fitted and a cover is attached to the front face of the cylindrical block to cover the front opening of the cylindrical block. 2. The front surface of the cylindrical block and the front surface of the sliding block are formed on the same surface at least on the inner peripheral side, and the cover covers the inner peripheral side portion of the front surface of the sliding block over the entire range of opening and closing of the chuck claw. A rotary chuck device having a cover characterized in that it has a structure that covers the chuck without opening it.
