PURPOSE: A vibration ripper including an eccentricity vibration generator is provided to drastically improve vibration efficiency. CONSTITUTION: A vibration ripper including an eccentricity vibration generator comprises a main body (100), a tooth (200), a vibration generator (300), a connection unit (600), and an elastic member (700). The vibration generator comprises a first vibration generator including a first eccentric weight and a second vibration generator including a second eccentric weight. The first eccentric weight has the phase difference of an angle of 180 degrees from the second eccentric weight and is arranged in order to be rotated. A rotary axis of the main body is separated from a straight line connecting the rotary axis of the first vibration generator and the rotary axis of the second vibration generator and is located on the straight line dividing the line connecting both axes into two parts. |
