  • Patent number: 12221170
    Abstract: In a deflector device, when an external force acts on an deflector body while at a deployed position such that the deflector body is rotated in a stowing direction, even if further rotation of the deflector body in the stowing direction is restricted, the deflector body is rotated to the deployed position by an urging force of a torsion coil spring when the external force acting on the deflector body is released. This enables the deflector body to be rotated to the deployed position from anywhere over an entire rotatable range in the stowing direction by the urging force of the torsion coil spring. Thus, the torsion coil spring is able to rotate the deflector body to the deployed position in a suitable manner.
