Abstract
Provided is a conveyance device configured to lift and move an object. The conveyance device includes a base and at least three rod portions. Each of the at least three rod portions is rotatable about a rotation axis extending along an up-down direction and has a projection. The projection protrudes from a first side surface in a direction away from the rotation axis and does not protrude from a second side surface. A distance from the rotation axis to a most protruding portion of the projection is greater than a distance from the rotation axis to the second side surface.
