Patent ID: 7963478

Claim:
A wing-flapping flying apparatus, comprising: a body; a rotating shaft rotatably joined to the body; driving means for rotating the rotating shaft and periodically reversing a rotational direction of the rotating shaft; a plurality of wing parts connected to the rotating shaft so as to be rotated together with the rotating shaft and to be relatively torsionally rotated with respect to the rotating shaft; means for restricting a relatively torsional rotation range of the wing part with respect to the rotating shaft; and means for relatively torsionally rotating the wing part during reversion of a rotational direction of the rotating shaft, wherein the means for relatively torsionally rotating the wing part comprises a pin member fixed to the body so as to correspond to a reversion location of the rotational direction of the rotating shaft; and a first protrusion formed on the wing part so as to contact the pin member during reversion of the rotational direction of the rotating shaft.
