The adjusting mechanism is made in the form of two coaxially arranged cylinders carrying the unbalance weights and joined together by joining members provided on their engageable surfaces. One of the cylinders is rigidly mounted on the drive shaft, while the other cylinder is mounted so as to be turnable and axially traversable.
