Claims

[Scope of utility model registration request]

The rotary shaft is rotated by a drive source through a transmission and fixed in any direction by a rotary disk, and the rotary shaft has a square shaft portion, and the square shaft portion of the rotary shaft is rotated by a drive source and fixed in any direction by a rotary disk. A hollow spindle having a first spur gear rotatably provided therein so as to be slidable thereon, a second spur gear meshing with the first spur gear being provided, and holding a rond on the second spur gear; is fixed through the center of the second spur gear, and a gear case is provided that covers the first spur gear and the second spur gear, and a rond that is integrated with the hollow spindle and inserted into the hollow spindle is gripped on the upper part of the gear case. A hydraulically operated chuck is provided to rotate the rond together with the hollow spindle, a hydraulically operated holder is provided below the hollow spindle to hold the rond, and the gear case is hydraulically operated along the rotation axis together with the hollow spindle and the chuck. A hydraulically fed boring machine with a rotating hollow spindle, which is moved up and down by a jack.
