In some embodiments, the minimum length (eg, D1 ) through which the pin portion 452 protrudes may be about 9 mm to about 13 mm. In some embodiments, the maximum length (eg, D2 ) through which the pin portion 452 protrudes may be about 16 mm to about 20 mm. In some embodiments, the difference between the maximum length (eg, D2) through which the fin portion 452 protrudes and the minimum length (eg, D1) through which the fin portion 452 protrudes may be about 3 mm to about 11 mm. .

In some embodiments, the maximum rotation angle θ of the pivoting emergency lever 300 may be about 105° to about 110°.

As described above, in the actuator assembly according to some embodiments, actuation of the locking pin 450 may be recognized by the switch 500 and the protrusion 458 of the locking pin 450 in contact with the switch 500 . That is, the driving of the locking pin 450 may be recognized without a separate electrical device (eg, a metal member, etc.) provided in the locking pin 450 to recognize the driving of the locking pin 450 . Accordingly, a structurally simple and cost-reduced actuator assembly can be provided.

Also, as described above, in the actuator assembly according to some embodiments, the emergency lever 300 may be fastened to the second shaft portion 432 having a semicircular cross-section. Accordingly, an actuator assembly with enhanced fastening properties can be provided.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but may be manufactured in various different forms, and those of ordinary skill in the art to which the present invention pertains. It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
