Abstract

A door mirror structure comprises a mirror unit and a support member fixing the mirror unit to a frame member inside a side door. The mirror unit comprises a door-mirror body portion, 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 and rotatably supporting the door-mirror body portion and the mirror base between a mirror-use position and a mirror-storage position, and an electromotive rotational unit rotating 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. The electromotive rotational unit is provided inside the side door.

First claim

What is claimed is:

1. A door mirror structure of a side door of a vehicle, comprising:
a mirror unit;
a frame member provided inside the side door; and
a support member fixing the mirror unit to the frame member,
wherein said mirror unit comprises a door-mirror body portion which is provided with a mirror to obtain a rearward visual field of the vehicle, a mirror base which has a tip-end portion fixed to said door-mirror body portion and a base-end portion provided away from said tip-end portion, a rotational support axis which is connected to said base-end portion of the mirror base and rotatably supports said door-mirror body portion and said 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, and an electromotive rotational unit which rotates said door-mirror body portion and said mirror base between the mirror-use position and the mirror-storage position around an axis line of said rotational support axis, and
said electromotive rotational unit is provided inside the side door.

2. The door mirror structure of claim 1 , wherein said rotational support axis is provided to pass between said support member and said frame member, a harness which is connected to a portion of the rotational support axis which is located at a point where the support member and the frame member overlap with each other in a direction perpendicular to an axis-line direction of the rotational support axis is provided, said frame member has a first opening where said harness is inserted at a portion thereof which overlaps with the support member, a size of said first opening is large enough to prevent the harness from contacting an inner peripheral edge of the first opening during the rotation of said door-mirror body portion and said mirror base, and said support member has a pair of fixation portions which are fixed to the frame member at both-side positions of the first opening.

3. The door mirror structure of claim 2 , wherein said frame member has a first ridgeline which is positioned at an outward side, in the vehicle width direction, of the frame member and extends in a vehicle longitudinal direction, said first opening is formed at a point where the first opening intersects said first ridgeline, and said pair of fixation portions of the support member are fixed to the frame member at respective positions which correspond to the both-side positions of the first opening in a direction along said first ridgeline and to vertical both-side positions of the first ridgeline.

4. The door mirror structure of claim 3 , wherein said support member further has a holding portion which has a second opening facing said first opening of the frame member and holds said rotational support axis in a state where the support member encloses an outer periphery of the rotational support axis, said pair of fixation portions are connected to both sides of said holding portion such that the fixation portions interpose the holding portion therebetween, and said harness is connected to the rotational support axis in a state where the harness is inserted into said first opening and said second opening.

5. The door mirror structure of claim 4 , wherein said support member further has a rib which connects said holding portion and said fixation portion.

6. The door mirror structure of claim 5 , wherein said support member is made of aluminum dicast.

7. The door mirror structure of claim 6 , wherein said rotational support axis is fixed to said base-end portion of the mirror base and configured to be rotatable around the axis line of the rotational support axis together with the mirror base by receiving a rotational drive force of said electromotive rotational unit.

8. The door mirror structure of claim 4 , wherein said frame member is a beltline reinforcement which extends in a vehicle longitudinal direction along a beltline of a window lower-end edge of the side door.

9. The door mirror structure of claim 8 , wherein said support member is made of aluminum dicast.

10. The door mirror structure of claim 9 , wherein said rotational support axis is fixed to said base-end portion of the mirror base and configured to be rotatable around the axis line of the rotational support axis together with the mirror base by receiving a rotational drive force of said electromotive rotational unit.

11. The door mirror structure of claim 1 , wherein said frame member is a beltline reinforcement which extends in a vehicle longitudinal direction along a beltline of a window lower-end edge of the side door.

12. The door mirror structure of claim 1 , wherein said support member is made of aluminum dicast.

13. The door mirror structure of claim 1 , wherein said rotational support axis is fixed to said base-end portion of the mirror base and configured to be rotatable around the axis line of the rotational support axis together with the mirror base by receiving a rotational drive force of said electromotive rotational unit.

14. The door mirror structure of claim 1 , wherein said frame member has a first ridgeline which is positioned at an outward side, in the vehicle width direction, of the frame member and extends in a vehicle longitudinal direction, and said support member is fixed to the frame member at respective positions which correspond to vertical both-side positions of the first ridgeline.
