PROBLEM TO BE SOLVED: To provide an optical disk drive device in which an optical axis of a laser beam irradiated from an optical pickup can be adjusted by a pair of opposing chassis and work efficiency in the assembling step of the device can be remarkably increased. SOLUTION: A first chassis to which the optical pickup is assembled is a frame of an almost rectangular shape having an opening part at a center, a hook type engaging piece is formed at one side of long sides of the frame, a screw insertion hole is formed at the other long side, a second chassis to which a turn table is assembled is a frame of an almost rectangular shape having an opening part at a center, an engaging part engageable with the hook type engaging piece is formed at one side of long sides of the frame, a screw hole being able to screw on a engaging screw inserted through the screw insertion hole is formed at the other long side, the hook type engaging piece is engaged with the engaging part and an engaging screw of the prescribed length is screwed to the screw hole through the screw insertion hole, so that the first chassis and the second chassis are arranged opposite to each other and they are fixed in a state in which the prescribed interval is kept.
