PROBLEM TO BE SOLVED: To smoothly make a start and a stop of a vibration mechanism without a vibrating body undergoing resonance by providing a moving eccentric weight in which eccentricity of a shaking axis is freely rotatable from an angle of 0 to a maximum eccentric angel position and energizing the moving eccentric weight in the direction of the eccentricity of 0 by a pressing member. SOLUTION: A vibration type compacting machine such as a vibrating roller travels by rotating a rolling wheel 1 by a traveling driving hydraulic motor 24. When a shaking axis 10 is rotated by driving a shaking driving hydraulic motor so as to drive the vibrating roller, a moving eccentric weight 4 overcomes moment generated by pressurization of a pressing member 13 at a certain number of revolution and is rotated around an axis 3 to a maximum eccentricity position. In this state, the rotation of the shaking axis 10 is increased, and the vibrating roller is operated in a stationary rotation state. On the other hand, when the rotation of the shaking axis 10 is decreased from the stationary rotation state, the moving eccentric weight 4 is rotated around the axis 3 in the direction that makes the eccentricity zero by the pressing member 13 at a certain number of revolution or less to return the moving eccentric weight 4 to a neutral position. |
