PURPOSE: An oscillator for a vibration compensation is provided to precisely and easily control the amplitude of the exciting force in a wide range by selecting the number of pendulum and mass. CONSTITUTION: An oscillator for a vibration compensation comprises a casing(1), a first rotating unit(2), a second rotating unit(3) and a driving portion(4). The casing has two stages structure consisting of a lower plate(11), a side plate(12), an upper plate(13) and a center plate(14). The case is included in the upper end. The first rotating unit comprises a rotary shaft(21), a gear(22), an eccentric rotation board(23) and a compensatory rotation board(24). The rotary shaft is coupled in the upper plate and center plate. The second rotating unit comprises a rotary shaft(31), a gear(32), an eccentric rotation board(33) and a compensatory rotation board(34). The driving portion comprises a driving motor(41) rotating the first and second rotating units.
