To prevent a supporting pin from bending and breaking at the time of transportation only with parts unit by constituting a vibration isolator for damping vibration by a damper fixed to a first frame, and the supporting pin whose one end is formed integratedly with the damper and the other end is fixed to a second frame.
In a vibration isolator 12 arranged between a frame 9 fixed to a vehicle and the like and a frame 10 in which a signal regenerating mechanism part of an onboard disk regenerator, a damper 13 in which viscous oil is sealed is arranged, and one end of a supporting pin 14 is fixed to a thin wall part 13a of the damper 13. The other end of the supporting pin 14 is pressed-into a press-in hole 10a of the frame 10. The damper 13 is fixed to the frame 9 by a damper holder 15 fixed to the frame 9 by a screw 16. Even if vibration is applied on the frame 9, its vibration can be damped effectively, and it is possible to prevent the supporting pin 14 from bending and breaking without concentrating stress on the supporting pin 14.
