1. An alignment device comprising:
a support base having a cylinder hole for incorporating an axially transferable lock piston, the support base being attached to a conveying device;
a mounting plate transferably abutted in a movable direction on a front surface of a fastening holder that is fixed to the support base, a gripping member being attached to the mounting plate;
a movable ring provided with a sliding part that is transferably engaged with the fastening holder in the movable direction, the movable ring being fixed to the mounting plate;
an axis conforming holder arranged between the fastening holder and the mounting plate, and having a first holding force that is driven by the lock piston and causes a reference axis of the mounting plate to conform with and lock a reference axis of the fastening holder; and
a force canceling holder provided between the fastening holder and the movable ring, and having a second holding force that admits a state where the mounting plate is transferable in the movable direction and that cancels a first-direction force applied to the mounting plate, the first-direction force being a force in a direction of shifting the reference axis of the mounting plate from the reference axis of the fastening holder,
wherein the force canceling holder is turned on and off by a fluid pressure actuating mechanism.
