PROBLEM TO BE SOLVED: To provide a disk conveyance device capable of, even when an overload is applied due to a forcible insertion of a disk by a user, releasing the overload to prevent a gear train from being subject thereto resulting in a damage.SOLUTION: The disk conveyance device comprises: drive rollers 6a and 6b each coming into direct contact with an inserted disk and holding the disk at both sides to convey the disk while rotating the disk with a drive force of a roller; a gear train 8a-8c interposed between roller gears 6e and 6f which are provided coaxially with the drive roller to transmit the drive force; and a roller arm 7a constituted of a molded member for rotatably holding the gear train 8a-8c including roller gears 6e and 6f along with the drive rollers 6a and 6b. The bearing portions 31 and 32 formed on the roller arm 7a and shafts 34 and 35 of the roller gears 6e and 6f are arranged to be flexibly deformable in a normal direction perpendicular to the axle of the gear. When an overload is applied due to disk insertion, the elastic deformation allows the roller gears and the gear train to be engaged from each other.
