Further, since the rear part of the Glen tank 20 is vibrated, it is only necessary to connect the vibration part 32 and the vibration transmission arm 34 by the vibration transmission shaft 33, so that the transmission structure can be simplified.
Further, since the vibration transmission shaft 33 transmits the rotation of the spiral rotation shaft 35 on the front side of the Glen tank 20, the rotation transmission configuration is simplified.

Thus, the vibrating body 37 of the vibrating portion 32 is formed in an L shape by the vertical axis portion 40 and the horizontal axis portion 41, and each of the vertical axis portion 40 and the horizontal axis portion 41 is locked to the tank side plate 31.
