A disc player is provided with: a turn table ( ) for rotating an information record disc, which is placed on the turn table; a clamper ( ) for holding the information record disc between the clamper and the turn table; a chassis ( ) on which at least one of the clamper and the turn table is mounted and which has a rotation shaft ( ) parallel to a main surface of the information record disc held between the clamper and the turn table; a driving device ( ) for transmitting a driving force to the chassis so as to rotate the chassis with the rotation shaft at a rotation axis; and an optical pickup ( ) for at least reading a signal from the information record disc held between the clamper and the turn table while the disc is rotated on the turn table. A gap (W) is prepared between the rotation shaft and a bearing ( ) for the rotation shaft in a direction parallel to the main surface such that the rotation shaft has a play in the direction parallel to the main surface.
