An overhead transport vehicle includes an elevator including a base and a first support supporting the base to be vertically movable from below in a vertical direction through a vibration isolator. The vibration isolator includes a first biasing portion in contact with both of the support and the base to urge a first body and the base in a direction away from each other, and a second biasing portion at one of the first body and the base to come into contact with both of the first body and the base and urge the first body and the base in a direction away from each other when a load equal to or greater than a predetermined value is applied to the first biasing portion.
