Abstract
PURPOSE: To effectively perform chamfering of the penetrated hole opening part formed on a cylinder by allowing the plunger having the chamfer part arranged to be shifted by fluid pressure.
CONSTITUTION: A body 3 is inserted into a cylinder 4, and on the body, a fluid introducing passages 27 and a vacant space 8 communicating to the passage are formed. In the space 8, a plunger 13 is arranged slidably which is provided with a chamfer part 12 at the top end. When fluid is flowed under pressure into the passage 27 and the plunger 13 is operated, the chamfer part of the plunger is pushed onto the cylinder inside opening end in the penetrated hole 7, and chamfering is performed effectively on the cylinder inside opening end part in the penetrated hole 7.
