Claim:
A power drive unit of a type that is mountable to a support portion of an aircraft deck structure, the power drive unit comprising: (a) an elongated yoke having a pivot end and an opposite end, the pivot end being constructed and arranged for pivotal connection to the support portion of the aircraft deck structure along a pivot axis; (b) a drive roller rotatably mounted to the yoke about a roller axis; (c) at least one resilient member constructed and arranged to be disposed between the opposite end of the yoke and the support portion of the aircraft deck structure; (d) a drive motor coupled to the drive roller operable to selectively rotate the drive roller about the roller axis in two opposed directions; and (e) a reaction member connected to the drive motor, the reaction member being constructed and arranged to be at least partially movably engaged with the support portion of the aircraft deck structure to permit at least some pivotal movement between the yoke and the support portion of the aircraft deck structure, and to substantially prevent rotation of the drive motor relative to the yoke.
