A stopper portion includes a first protruding portion protruding from the end face of the first attachment portion closer to the outside in the main load input direction toward the outside in the main load input direction; and a second protruding portion protruding from the end face of the first attachment portion closer to the outside in the main load input direction toward the outside in the main load input direction, being spaced apart from the first protruding portion so as to be in a non-contact state with the first protruding portion, being thinner than the first protruding portion in the main load input direction, and having a protruding end in which a distance between the protruding end and the contact surface is longer in the main load input direction than a distance between a protruding end of the first protruding portion and the contact surface.

Vibration isolation structure

A vibration isolator includes: a pair of opposing members fixed to a vehicle body of the vehicle to be located on both sides of a protrusion protruding from an outer circumferential edge of the power train in a direction perpendicular to the principal axes of inertia to oppose to each other in the direction about the principal axes of inertia; a precompressed part provided on part of each of the opposing members facing the protrusion to be precompressed by the opposing member and the protrusion in the direction about the principal axes of inertia; and a contacting part provided on part of each of the opposing members facing the protrusion to be spaced from the protrusion, and contacts the protrusion when the power train vibrates in the direction about the principal axes of inertia.
