PROBLEM TO BE SOLVED: To make loads on a driving source constant regardless of the transport direction of a disk. SOLUTION: A roller arm 46A is formed with a first engagement part 51 with which a roller shaft 37a of a transport roller 37 long in the transport direction of an optical disk 1 is engaged, and a chassis 44 is formed with a second engagement part 53 with which the roller shaft 37a of the transport roller 37 is engaged so as to intersect the first engagement part 51. The roller shaft 37a is rockable in the intersecting first and second engagement parts 51 and 53. Thus, the transport direction of the roller shaft 37a is regulated by a long side of the second engagement part 53 of the chassis 44 to be able to prevent the occurrence of external force to the roller arm 46, so that the loads on the driving source can be made constant regardless of the transport direction.
