Provided is a rotor craft that is capable of changing the torsional angle of a blade with a relatively simple configuration by suitably driving an actuator, even if the actuator is a low-power actuator. A helicopter (10) includes torsion applying mechanisms (40), each of which twists a proximal end portion of a corresponding one of blades (18) relative to a distal end portion of the corresponding blade (18) about a center axis (A) of the blade (18). Each of the blades (18) includes: a spar (23) including a proximal end portion connected to a hub (17); and a skin (24) in which the spar (23) is inserted, such that a distal end portion of the skin (24) and a distal end portion of the spar (23) are connected to each other, and such that other portions of the skin (24) than the distal end portion are rotatable relative to the spar (23) about a center axis of the spar (23). The hub (17) includes: a hub body (20) mounted to a main rotor shaft (16); and a hub arm (21) that connects the spar (23) to the hub body (20).
