CONSTITUTION: A handle case 2 is fixed to a door side, and a handle 4 to operate and rotate an inner case 3 allowable to rise and set is installed to the handle case 2. A projection of the handle 4 to the outer side is controlled by a bolt member 7. The bolt member 7 is operated by the cam 6 of a cylinder lock 5 housed in the tube body of the handle 4. The cylinder lock 5 is screwed up to a nut 10 fixed in the tube body of the handle 4, and a part of a rotation blocking device 12 inserted to the side surface of the nut 10 is abutted against the cutting surface 5b of the cylinder lock 5. The rotary shaft of a cam 6 is fitted to a bolt at the rear side of the inner tube of the cylinder lock 5, in the condition energizing the rotary shaft to the inner tube surface side by a spring. The cylinder lock 5 is fixed to the nut 10 in the tube body of the handle 4 so as to prevent the removal of the cylinder lock 5, and furthermore, the rotation of the cylinder lock is also blocked, so as to prevent the pulling-out with the rotation.
