1. A transport vehicle comprising:
a pair of swing suppression units configured to contact a transported object from front and rear in a traveling direction;
a moving mechanism configured to move at least one of the swing suppression units in the traveling direction between a first position contacting the transported object and a second position spaced away from the transported object by a drive of a drive unit; and
a buffer mechanism configured to allow the swing suppression unit that has been moved to the first position by the drive of the drive unit to move to the traveling direction after stopping the drive of the drive unit; wherein
the buffer mechanism includes:
an operation portion coupled to the swing suppression unit and configured to perform a movement of an operation amount in accordance with an amount of movement of the swing suppression unit in a direction toward the second position;
a first bias portion configured to bias the operation portion so that the swing suppression unit presses the transported object; and
a second bias portion configured to act on the operation portion when the operation amount of the operation portion is greater than a predetermined amount and to bias the operation portion so that the swing suppression unit presses the transported object; and

the moving mechanism includes:
a supporting portion rotatable bidirectionally around a rotation shaft and configured to support the swing suppression unit;
a drive shaft configured to rotate by a drive of the drive unit;
a crank portion configured to rotate bidirectionally by rotation of the drive shaft; and
a connecting portion coupled at one end to a position that is eccentric to the drive shaft of the crank portion so as to be rotatable bidirectionally and coupled at the other end to a position that is eccentric to the rotation shaft of the supporting portion so as to be rotatable bidirectionally.
