<P>PROBLEM TO BE SOLVED: To keep a door close when a casing drops. <P>SOLUTION: The lock device includes: a support part for supporting a lock lever for locking a door attached to a casing so as to be opened and closed in a close state to rotate with a lever rotating shaft as a center in one rotational direction for locking the door to the casing and the other rotational direction for releasing the lock; and an energization part for energizing the lock lever to rotate in the one rotational direction. The lever center of gravity of the lock lever is positioned in the lever rotating shaft so that even when the casing drops in a state that the door is locked to the casing by the lock lever according as the lock lever is energized by the energization part, an impulsive force to the lock lever when the casing drops or a repulsive force or centrifugal force generated due to the bounce or rolling accompanied by the drop of the casing can be received at the lever center of gravity in the lever rotating shaft, and that an external force with which the lock lever rotates to the other rotational direction can be prevented from being added to the lock lever. Thus, it is possible to maintain the lock state of the door to the casing, and to keep the door close when the casing drops. <P>COPYRIGHT: (C)2013,JPO&INPIT |
