PURPOSE: A cap(100) is provided to reduce twisting and vibration when a pile such as a steel pipe, concrete pile or H-beam is driven by a pile driver, by which torsion is prevented and also noise thereby is reduced by applying a noise reducing member. CONSTITUTION: A cap(100) comprises a top panel(10) of a housing form corresponding to the inner circle profile of a bottom cylinder to connect the bottom cylinder of a pile driver, and a bottom panel(20) having the structure which the top face of a H-beam(200) is integrated with the bottom of the top panel(10) and fitted thereto. Further, an eye bolt(30) is also mounted at the center of gravity of the top panel(10) for being hung on a crane while moving the pile cap(100).
