A deflector device includes a deflector body that is configured to be deployed in front of a front wheel of a vehicle by being rotated in a deploy direction and to suppress airflow onto the front wheel, and that is configured to be stowed in a body of the vehicle by being rotated in a stow direction; a drive member that is configured to transmit drive force; and a transmission member that is provided with a projection that protrudes in a radial direction thereof and that is configured to be engaged with the drive member such that drive force from the drive member is transmitted to the transmission member and the deflector body is rotated.

Deflector device

A flow deflecting device includes a flow deflecting body configured to be deployed and retracted; a rotational mechanism, whereby the flow deflecting body is rotatable in an engaged state at the rotational mechanism; and a limiting mechanism, whereby rotation of the flow deflecting body is limitable in an engaged state at the limiting mechanism. In a case in which the flow deflecting body in a deployed position is acted upon by a first external force, engagement with the rotational mechanism is released, and the flow deflecting body is rotated in the retraction direction in the engaged state at the limiting mechanism. In a case in which the flow deflecting body in a retracted position is acted upon by a second external force, engagement with the limiting mechanism is released, and the flow deflecting body is rotated in the retraction direction in the engaged state at the rotational mechanism.

Flow deflecting device

A deflector device having a deflector body that is configured to be deployed in front of a front wheel of a vehicle by being rotated in a deploy direction and to suppress airflow onto the front wheel, and that is configured to be stowed in a body of the vehicle by being rotated in a stow direction; a rotation shaft that is configured to rotate the deflector body by rotation of the rotation shaft; and a transmission member that is configured to transmit drive force to the rotation shaft to rotate the rotation shaft, and to be moved, when an external force has acted on the deflector body such that the deflector body is rotated in the stow direction from a stowed position, by movement of the rotation shaft in an axial direction being limited.

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.

In a door mirror device for a vehicle, an engaging ring that rotates together with a case is provided on an interior floor portion of the case. A restricting ring is provided at the upper side of the engaging ring and is urged toward the lower side by a coil spring. The restricting ring is movable to a side in an axial direction of a support shaft of a stand, but relative rotation of the restricting ring with respect to the support shaft is restricted. Therefore, in a state in which upper side protrusion portions of the engaging ring go out from restricting recess portions of the restricting ring, the restricting ring is moved toward the upper side. Consequently, movement of the case toward the upper side can be suppressed.

Viewing device for a vehicle

In a door mirror device for a vehicle, a stopper groove of a case and a stopper of a stand are provided so as to be superposed with a restricting ring in an axial direction of a support shaft of the stand. Therefore, in comparison with a structure in which the stopper groove of the case and the stopper of the stand are provided at the outer side in an axis-orthogonal direction (radial direction) of the support shaft of the stand relative to the restricting ring and an engaging ring, an increase in size of the case and stand to a side in the axis-orthogonal direction of the support shaft may be suppressed.

In a vehicle door mirror device, a through hole of a case is penetrated by a support shaft so as to rotatably support the case on the support shaft. Lower ribs are formed in a protruding state at a peripheral face of the through hole, and protrusion leading end faces of the lower ribs are capable of contacting the support shaft. A gap dimension between the peripheral face of the through hole and the support shaft can accordingly be made small, thereby enabling rattling of the case with respect to the support shaft to be suppressed. Moreover, the contact surface area between the peripheral face of the through hole and the support shaft can be made small, thereby enabling an increase in sliding resistance between the peripheral face of the through hole and the support shaft to be suppressed.

Vehicle visual recognition device

In a vehicle door mirror device, in a contact tube of a motor base, projection leading end faces of second contact ribs are disposed at radial direction inside of a circular circumferential face in which projection leading end faces of first contact ribs are disposed. The projection leading end faces of the second contact ribs have a smaller gap dimension to a support tube of a support shaft than gap dimension of the projection leading end faces of the first contact ribs to the support tube in a state in which a drive body is not tilted with respect to the support shaft. This thereby enables tilting of the drive body with respect to the support shaft to be effectively suppressed.

Disclosed in a door mirror device capable of continuously emitting light from two light guides. The door mirror device comprises: a first light-emitting light guide arranged in the visor part of a door mirror foldably mounted on the door mirror support part of a vehicle; a second light-emitting light guide provided in the door mirror support part, an end of the second light-emitting light guide facing to an end of the first light-emitting light guide so as to have continuity with the first light-emitting light guide; and a light source configured to emit light toward the first light-emitting light guide and the second light-emitting light guide, the light source being provided in the visor part.
