PROBLEM TO BE SOLVED: To provide only one guidance line for transverse traveling in an unmanned carrier for performing longitudinal traveling and transverse traveling along the guidance line laid on a road surface. SOLUTION: The unmanned carrier 10 is provided with: drive wheels 12 and 13 arranged at the front and rear ends of a body 11; an guidance line sensor 14 for detecting the guidance line 31 laid on the road surface; and a control part 16 for controlling the drive wheels 12 and 13 according to the output of the guidance line sensor 14. Steering is controlled along the guidance line 31 by the control part 16 so that longitudinal traveling and traverse traveling orthogonal to the longitudinal traveling can be achieved. The control part 16 controls drive wheels 12 and 13 in backward and forward traveling by an independent steering system and controls the drive wheels 12 and 13 in a two-wheel speed difference steering system in transverse traveling while holding them in transverse parallel directions in transverse traveling. Thus, time and labor and laying costs can be reduced by providing only one guidance line 31 for transverse traveling. COPYRIGHT: (C)2010,JPO&INPIT
