In a conveying apparatus wherein a carriage is driven by a linear motor to run along guide rails, the guide rails comprise two parallel guide members, each having a first guide surface that prevents lateral movement of the carriage, and a second guide surface that prevents vertical movement of the carriage. The carriage comprises first wheels disposed between upper and lower surfaces of the carriage for rolling along the first guide surfaces and second wheels disposed spaced apart from the first wheels in the running direction of the carriage to roll along the second guide surfaces.
