description PROBLEM TO BE SOLVED: To relax the stress of a joint and to prevent abnormal vibration by improving a reversible rotation mechanism which controls vibration force by adjusting the phase difference between a stationary eccentric weight and movable eccentric weight in an eccentric weight type vibration generator. SOLUTION: The upper column of the representative figure is a conventional example, and the lower column of the figure is an embodiment. As shown by (B1), two parallel oil routes 21d for supplying pressure oil to a crossing communication hole 21c are bored from the side of a swivel part 21g, and no oil route is formed in the joint 21e. The two parallel oil routes 21d, as expressed by (B3) wherein its f-f cross section is drawn, are arranged symmetrically about the axis of a rotary shaft 21. COPYRIGHT: (C)2010,JPO&INPIT
