To provide a thrust generator capable of improving stability of rotation motion changing a pitch angle.SOLUTION: A thrust generator comprises: a first motor generating thrust of a rotary wing; a second motor for generating rotation motion for changing a pitch angle of the rotary wing; a first conversion part for converting the rotation motion of the second motor into linear motion; and a second conversion part for converting the linear motion obtained by conversion by the first conversion part into the rotation motion. The second conversion part has a support shaft for transmitting the rotation motion obtained by conversion by the second conversion part to the rotary wing, and an outer peripheral face of the support shaft has a plane which is tilted toward an axial direction of the support shaft toward a direction of the rotary wing.SELECTED DRAWING: Figure 12
