Provided is a locking mechanism of a disk device in which the impact resistance performance can be improved easily at a low cost. In the locking mechanism, a locking pin is provided in a casing and, at the same time, provided in a tray are a locking lever supported to be capable of oscillating having a locking part on the tip to be engaged with the locking pin, an ejection lever supported to be capable oscillation for pressing the locking lever so as to oscillate the locking lever to detach the locking part from the locking pin, and a movable piece holding unit for holding a movable piece provided in one end part of the ejection lever so as to set aside the ejection lever. Further, an ejection lever balance weight having a prescribed mass is provided on the opposite side to the ejection lever with respect to the oscillation center of the ejection lever.
