Claims

[Scope of utility model registration request]

In the buffer device, the buffer device includes an outer member and an inner member supported by a vehicle body and a power unit through brackets, and an elastic body that connects the inner member and the outer member and is fitted and held in the outer member. An elastic body that overlaps the bracket connected to the inner member in the axial direction is disposed on the inner surface side of the outer member, and the outer member of the elastic body is placed in a contact portion between the elastic body and the inner surface of the outer member. A buffer device characterized in that it is provided with a means for preventing it from falling off.
