Abstract
A gripping mechanism is attached to a mobile body to grip and convey a transportation article. The gripping mechanism includes a pinion provided to be rotatable about a rotation axis, and a first arm and a second arm disposed with the rotation axis being the center to be separated from the rotation axis by the same distance to grip the transportation article. When the pinion rotates in a predetermined direction, the first arm and the second arm move toward the rotation axis.
