Claims

[Scope of Claim for Utility Model Registration] 1. An outer cylinder that is suspended and retractably held on an aircraft body, etc., an orifice support tube that is fixed concentrically within the outer cylinder, and that can be slidably inserted between the orifice support tube and the outer cylinder. The other end of the swing lever, which has a wheel pivotally supported at its tip and is pivotally attached to the lower tip of the inner cylinder, and a collar circumferentially attached to the outer periphery of the lower tip of the outer cylinder. is pivotally connected to a rod, a cylindrical centering cam having a fitting recess at a predetermined position in the circumferential direction is coaxially fixed to the outer peripheral surface of the lower tip side of the orifice support tube, and the recess of the centering cam It has a structure in which a pin or cam that can be inserted into the inner cylinder protrudes from the inner peripheral surface of the upper end of the inner cylinder, and only when the inner cylinder is extended, the inner cylinder is required to fit into the recess on the cam surface and the pin or cam. A steering gear device for an aircraft, characterized in that it is held in position. 2. A cylindrical centering cam having a fitting recess at a predetermined position in the circumferential direction is coaxially fixed within the upper end of the inner cylinder, and a pin or cam that can be fitted into the recess of the centering cam is placed on the lower end side of the orifice support tube. The aircraft steering leg device according to claim 1, characterized in that it has a structure protruding from the outer peripheral surface.
