Stopper mechanism of slide rail

A stopper mechanism of a slide rail for protecting a slide rail that is attached to a main body and a housed unit so as to pull out the housed unit inside the main body from the main body, the stopper mechanism comprising:

• an auxiliary slider that is attached to the housed unit so as to be capable of moving a predetermined distance along the pull-out direction of the housed unit and which moves to a first position so as to come relatively closer to the housed unit in a state where the housed unit is housed inside the main body, and which moves to a second position so as to become relatively more distant from the housed unit in a state where the housed unit has been pulled out of the main body;
• and
• a stop unit provided in the main body and configured to stop the movement of the auxiliary slider in the pull-out direction, wherein
• the stopper mechanism stops the pulling-out of the housed unit by causing the auxiliary slider that has moved to the second position to stop by means of the stop unit at a position nearer to the main body than a maximum pull-out position up to which the housed unit is pulled out by the slider rail, and
• the stopper mechanism stops the pulling-out of the housed unit in a state where an end part on the side nearer to the main body in the pull-out direction of the housed unit has been pulled out from the front surface of the main body.
