PROBLEM TO BE SOLVED: To increase the slant moment, particularly at the time of moving forward, while maintaining the structural height to be small and protect phase adjustment mechanisms from being affected by the structural shape of unbalance bodies. SOLUTION: Two intermediate shafts 4 and 5 supported rotatably on a vibrator casing 1 in parallel with both unbalance shafts between both unbalance shafts 3a and 3b, and both intermediate shafts are connected in shape with the unbalance shafts 3a and 3b respectively toothed gears 7-10. The intermediate shafts 5, 4 are respectively rotated in the direction reverse to the unbalance shafts 3b, 3a, and two gears 9 and 10 are supported by the intermediate shaft 5, and the gear 9 is connected with the unbalance shaft 3a, while the gear 10 is connected with the unbalance shaft 3b, and the gear 10 is formed adjustably in the state of controlling the angle position to the shaft by phase adjustment mechanisms 10b, 11-15. |
