Claim 18:
19. A linear transport apparatus, comprising:
a transport cart;
a first roller to rotate about a first rotation shaft extending from the transport cart along a first direction;
a second roller to rotate about a second rotation shaft extending from the transport cart and forming an acute angle with the first rotation shaft; and
a rail sandwiched between the first roller and the second roller to extend along a track on which the transport cart moves, wherein
the rail includes
a first contact portion to come into contact with the first roller and restrict movement of the transport cart in the first direction and in a second direction perpendicular to a direction in which the rail extends and perpendicular to the first direction, and
a second contact portion to come into contact with the second roller and be parallel to the second rotation shaft,
the rail includes a portion in which a curvature of the track on which the transport cart moves is different from another portion, and
a position of the first contact portion along the first direction changes on the rail between rail portions having different curvatures.
