1. A tilt prop aircraft comprising a pitch control rod which changes pitch angle of a propeller while moving up and down along a rotational axis of a rotor, the tilt prop aircraft comprising:
a first longitudinal support member and a second longitudinal support member capable of tilting relatively to each other;
a tilt actuator disposed on the second longitudinal support member;
a first power transmission member rotated by the tilt actuator;
a second power transmission member fixed to the first longitudinal support member and coupled to the first power transmission member to transmit a rotational movement of the first power transmission member by turning 90 degrees in different planes;
a crank fixed to the second longitudinal support member and extending through a slot in the first longitudinal support member and protruding inwardly from the first longitudinal support member; and
a connecting rod connected to the crank so as to be relatively rotatable to the crank, and connected to the pitch control rod.
