Abstract

Claims (17)

1. A door mirror device of a side door of a vehicle, comprising:

a door-mirror body portion provided with a mirror to obtain a rearward visual field of the vehicle;

a mirror base having a tip-end portion fixed to the door-mirror body portion and a base-end portion provided away from the tip-end portion;

a rotational support axis connected to the base-end portion of the mirror base and rotatably supporting the door-mirror body portion and the mirror base between a mirror-use position where the mirror is visible from a cabin inside and a mirror-storage position which is located on an inward side, in a vehicle width direction, of the mirror-use position;

an electromotive rotational unit provided to rotate the door-mirror body portion and the mirror base between the mirror-use position and the mirror-storage position around an axis line of the rotational support axis; and

a control portion to control the electromotive rotational unit,

wherein said electromotive rotational unit is provided inside the side door, and said control portion controls said electromotive rotational unit such that said door-mirror body portion and said mirror base are rotated from said mirror-use position to said mirror-storage position when a storage active signal to start a storage operation is inputted, said door-mirror body portion and said mirror base are rotated from said mirror-storage position to said mirror-use position when a deployment active signal to start a deployment active operation is inputted, and said door-mirror body portion and said mirror base are rotated in a prescribed minute range centered at the mirror-use position so as to change an angle of the mirror when a mirror-face adjusting signal to adjust a mirror face is inputted.

2. The door mirror device of claim 1 , wherein said rotational support axis is provided to be inclined such that an upper side thereof is located on a vehicle forward side and on an outward side in a vehicle width direction.

3. The door mirror device of claim 2 , further comprising a memory portion to memorize positional information relating to a position of said door-mirror body portion and said mirror base after the door-mirror body portion and the mirror base have been rotated by said electromotive rotational unit in said prescribed minute range so as to change the angle of the mirror when said mirror-face adjusting signal is inputted to said control portion,

wherein said control portion controls the electromotive rotational unit such that the door-mirror body portion and the mirror base are located at a position corresponding to said positional information memorized by said memory portion when the door-mirror body portion and the mirror base are rotated from said mirror-storage position to said mirror-use position according to an input of said deployment active signal in a state where the door-mirror body portion and the mirror base take the mirror-storage position.

4. The door mirror device of claim 3 , wherein said control portion controls said electromotive rotational unit such that said door-mirror body portion and said mirror base are returned to a position corresponding to said positional information memorized by said memory portion in a case where a position of the door-mirror body portion and the mirror base is changed without being driven by the electromotive rotational unit.

5. The door mirror device of claim 4 , wherein said prescribed minute range corresponds to a range of ±5 degrees centered at said mirror-use position.

6. The door mirror device of claim 5 , wherein said rotational support axis is fixed to the base end portion of said mirror base and rotatable together with the mirror base around the axis line of said rotational support axis when receiving a rotational drive force of said electromotive rotational unit.

7. The door mirror device of claim 1 , further comprising a memory portion to memorize positional information relating to a position of said door-mirror body portion and said mirror base after the door-mirror body portion and the mirror base have been rotated by said electromotive rotational unit in said prescribed minute range so as to change the angle of the mirror when said mirror-face adjusting signal is inputted to said control portion,

wherein said control portion controls the electromotive rotational unit such that the door-mirror body portion and the mirror base are located at a position corresponding to said positional information memorized by said memory portion when the door-mirror body portion and the mirror base are rotated from said mirror-storage position to said mirror-use position according to an input of said deployment active signal in a state where the door-mirror body portion and the mirror base take the mirror-storage position.

8. The door mirror device of claim 1 , wherein said prescribed minute range corresponds to a range of ±5 degrees centered at said mirror-use position.

9. The door mirror device of claim 1 , wherein said rotational support axis is fixed to the base end portion of said mirror base and rotatable together with the mirror base around the axis line of said rotational support axis when receiving a rotational drive force of said electromotive rotational unit.
