To provide an aircraft landing gear lifting gear structure capable of lowering a landing gear by releasing connection between an output of a motor and an electrical linear actuator during emergency with a simple configuration.SOLUTION: A gear engagement releasing structure 40 comprises: a first gear 41 connected to a motor; a fitting pin 44 connected to the first gear 41 to extend in a direction perpendicular to an axial direction of the first gear 41; a ring-shaped pin guide 46 having a pin insertion groove into which the fitting pin 44 can fit; a second gear 42 connected to the ring-shaped pin guide 46 and an electrical linear actuator; and a slide shaft 43 provided inside the first gear 41, the ring-shaped pin guide 46, and the second gear 42 in a radial direction, to which the fitting pin 44 is connected. The slide shaft 43 is configured to be movable to a first position where the fitting pin 44 and the ring-shaped pin guide 46 are engaged with each other and a second position where the fitting pin 44 and the ring-shaped pin guide 46 are disengaged from each other.SELECTED DRAWING: Figure 2
