PROBLEM TO BE SOLVED: To provide a carrier capable of preventing each wheel from giving large impact to a road surface and preventing each wheel from rising up to run by corresponding to each recessed and projecting part on the road surface flexibly even when the carrier runs on the road surface having recessed and projecting parts. SOLUTION: This carrier is constituted in such a way that wheel support parts 13, 23 which are long in the forward and backward directions and turn vertically centered on a halfway part in the forward and backward directions are arranged on the right and left sides, load sensors 11s, 12s, 21s, 22s for detecting load received by wheels 11, 12, 21, 22 supported by the wheel support parts 13, 23 in the front and rear parts, respectively, are provided, and a running control means 32b controls running speed of each wheel 11, 12, 21, 22 based on the load detected by each load sensor 11s, 12s, 21s, 22s.
