The size of a propellant force generator in the axial direction of a rotational shaft of a motor is reduced while making the pitch angles of rotational blades driven by the motor variable. The propellant force generator (1) includes a propellant-force generating motor (2) adapted to generate a propellant force for rotational blades (H1 to H3), a pitch varying motor (5) adapted to generate a rotational motion for changing pitch angles of the rotational blades (H1 to H3), a rotation-linear motion converting unit (7) adapted to convert the rotational motion generated by the pitch varying motor (5) into a linear motion, and a linear motion-rotation converting unit (8) adapted to convert the linear motions converted by the rotation-linear motion converting unit (7) into rotational motions. At least a part of the linear motion-rotation converting unit (7) is located within the propellant-force generating motor (2).
