PROBLEM TO BE SOLVED: To realize variable adjustment of an amplitude of the axial vibration of a lateral vibration roller. SOLUTION: A cam rotating shaft line 16 of a driving cam 17 for axially driving the lateral vibration roller 10 is eccentric to the roller rotating shaft of the vibration roller 10 and arranged offset. The driving cam 17 is connected to a motor 42 for rotating the driving cam 17 around the cam rotating shaft line 16. Further, in the driving cam 17, a positional adjusting device 55 for positionally adjusting the inclination of a cam course 18, which is made of the groove 19 of the driving cam 17, is provided. |
