A driving device and chassis for a disk tray of an optical disk drive is disclosed. The tray of the optical disk drive is connected to a chassis. The front end of the chassis is installed with a driving means. By the driving of the driving means, the tray of the disk may open or close. A driven wheel serves to drive a decelerating gear. The axial hole of the driven wheel is positioned in the chassis by a rotary shaft retainer. The rotary shaft retainer is a rotary shaft screw. An upper half of said rotary shaft screw is an axial portion, and a lower half of said rotary shaft screw has a thread, and the axial portion of the rotary shaft screw serves to be pivotally connected to a thread of a short column protruded from said chassis. The thread is locked to a joint of the chassis; or a rotary shaft retainer is integrally formed with the chassis through a rotary shaft. The chassis is made of a general material. The manufacturing process is easy and cost of the chassis of an optical disk drive is reduced.
