To secure positioning accuracy of an axial center of a linear motion body performing linear motion converted into rotational motion for changing pitch angles.SOLUTION: A thrust generating device includes a first motor which generates thrust of a rotor, a second motor which generates rotational motion for changing pitch angles of the rotor, a first conversion part which converts the rotational motion of the second motor to linear motion, and a second conversion part which converts the linear motion converted by the first conversion part to the rotational motion. The second conversion part includes a linear motion body which can linearly move in accordance with the linear motion converted by the first conversion part, a rack-and-pinion which converts the linear motion converted by the first conversion part to the rotational motion, and a lift guide which guides the linear motion of the linear motion body in an axial direction of a rotary shaft of the first motor. A rack of the rack-and-pinion is supported by the linear motion body, and a pinion of the rack-and-pinion is supported by a support shaft side of the rotor.SELECTED DRAWING: Figure 15
