An optical disk device in which the thickness of the device is not increased, and interference between the bottom surface of an optical pickup unit (OPU) and a bottom case of the device is prevented upon emergency ejection of an optical disk without moving the optical pickup unit to an outermost peripheral position of the disk in the event of abnormality such as power shutdown during an operation in the optical disk device. A support mechanism having a coil spring is provided at shaft-holders in three of four positions of a guide main shaft and a guide sub shaft to support an OPU, to perform skew adjustment. In another position, a support mechanism having a plate spring is provided such that, upon emergency ejection, the interference between the bottom surface of the OPU and the bottom case is mitigated.
