In the above-mentioned conventional door mirror, since it is necessary to stably support the heavy door mirror body on the door side, the vertical width of the cross section of the mirror base is set large, and the ends of the mirror base on the door side are separated vertically. It is connected to the bracket on the door side at multiple positions. Therefore, the vertical width of the base cover that covers the outside of the mirror base tends to be large. This is not desirable in order to improve the appearance from the outside of the vehicle and reduce the running resistance.

Currently, as measures against this, a plate-shaped support block portion having a narrow vertical width that rotatably supports the door mirror body and a mounting block portion that bends downward from the end of the support block portion on the door side and extends. We are considering covering the peripheral area of the support block with a base cover. In this case, the mounting block portion is inserted into the inside of the door through the opening of the door, and is coupled to the member in the door at a plurality of positions separated vertically.
On the other hand, when this structure is adopted, it is desired to divide the base cover into upper and lower parts and surround the support block portion with the upper cover and the lower cover from the viewpoint of moldability and assembling property.

However, if the base cover is divided into an upper cover and a lower cover, there is a concern that a substantially horizontal misalignment may occur on the front end side of the traveling wind guide portion extending forward from the cover main portion. In particular, when the door mirror body is rotated, if an external force in the rotation direction acts on the upper cover due to friction or the like, the tip side of the traveling wind guide portion of the upper cover is likely to be displaced with respect to the lower cover or the outer surface of the door. ..

Therefore, the present invention is to provide a door mirror capable of suppressing the misalignment of the traveling wind guide portion while making the base cover thin and vertically divided.

In order to solve the above problems, the door mirror according to the present invention has the following configuration.

A locking projection that is projected from the running wind guide portion of either one of the lower covers and extends in the vertical direction, and the running wind guide portion of either the upper cover or the lower cover are provided with the engagement. A plate-shaped support block portion that includes a locking portion into which a stop protrusion is fitted, the mirror base is mounted below the door mirror main body to support the door mirror main body, and the vertical direction is the plate thickness direction. A mounting block portion extending downward from the end on the door side of the support block portion, being inserted into an opening provided in the door facing the outside of the vehicle, and being coupled to the inside of the door, and the above. It is characterized in that it is provided in a support block portion, is arranged between the traveling wind guide portions of the upper cover and the lower cover, and is provided with a penetrating portion into which the locking projection is fitted.

The traveling wind guide portion has a front end portion formed in a sharp shape in which the width in the vehicle width direction of the vehicle is gradually reduced from the cover main portion toward the front side, and the locking projection is provided. May be arranged in the vicinity of the front end portion.

The traveling wind guide portion, which is the other of the upper cover and the lower cover, connects a plate-shaped piece projecting from the inner surface of the base cover and extending in a substantially horizontal direction, and the plate-shaped piece and the inner surface. A reinforcing rib for restricting the fall of the plate-shaped piece may be provided, and the plate-shaped piece may be provided with the locking portion into which the locking projection is fitted.

The support block portion includes a support piece extending toward the front side at the front end portion of the support block portion, and the penetration portion is in the vicinity of the end portion in the extending direction of the support piece. It may be arranged.

In the present invention, the mirror base includes a support block portion having a narrow vertical width and a mounting block portion extending downward from the end portion of the support block portion and being coupled into the door, and the base cover is a thin-walled support block portion. It is configured to surround the perimeter of the door. Therefore, the base cover can be made thin to improve the appearance and reduce the running resistance.

<Effect of embodiment>
As described above, the door mirror 10 of the present embodiment includes a plate-shaped support block portion 13A and a mounting block portion 13B in which the mirror base 13 bends downward and extends from the end portion of the support block portion 13A. The portion 13B is inserted into the opening 16 of the front door 1 and coupled to the inside of the front door 1. Therefore, the mounting block portion can be stably fixed in the front door 1 while the door mirror main body 12 is supported by the support block portion 13A having a narrow vertical width.

Further, in the door mirror 10 of the present embodiment, since the base cover 14 surrounds the support block portion 13A having a narrow vertical width, the cover main portion 14a of the base cover 14 and the traveling wind guide portion 14b have a narrow vertical width. It can be made into a thin shape. Therefore, according to this configuration, the appearance of the base cover 14 can be improved, and the running resistance of the base cover 14 when the vehicle is running can be further reduced.

The door mirror 10 of the present embodiment has a configuration in which the base cover 14 engages the upper cover 14U and the lower cover 14L with each other by a snap fit due to the relationship between the moldability and the assembling property. The traveling wind guide portion 14b of the lower cover 14L is restricted from being displaced in the substantially horizontal direction by fitting the locking projection 25 on the upper cover 14U side into the locking hole 26a on the lower cover 14L side. Therefore, the upper cover 14U and the lower cover 14L travel when friction due to the rotation of the door mirror main body 12 or when a force around the axis o1 (a force in a substantially horizontal direction) acts on the upper cover 14U and the lower cover 14L from the outside. It is possible to reliably regulate the position shift in the substantially horizontal direction by the wind guide portion 14b.
Further, when a vertical force acts on the base cover 14 from the outside or the like, in the traveling wind guide portion 14b, the force is applied in the diagonally upward or diagonally downward direction with the portion overlapping the door mirror main body 12 in the vertical direction as a fulcrum. Is added. Here, since the locking projection 25 extends in the vertical direction, the locking projection 25 comes into contact with the edge of the locking hole 26a against a force obliquely upward or diagonally downward, so that movement is restricted.
Further, in the door mirror 10 of the present embodiment, the locking projection 25 on the upper cover 14U side is also fitted into the through hole 29 of the support block portion 13A, so that the traveling wind guide portion 14b of the base cover 14 is the front door 1. Displacement in the direction of separation from the outer surface can also be regulated.

Therefore, when the door mirror 10 of the present embodiment is adopted, the base cover 14 is made thin to improve the appearance and reduce the running resistance, and the running wind guide portion 14b of the base cover 14 is substantially horizontal and up and down. It is possible to suppress the misalignment of the direction.

Further, in the door mirror 10 of the present embodiment, the traveling wind guide portion 14b has a front end portion 14b-e formed in a sharp shape in which the width in the vehicle width direction of the vehicle is gradually reduced toward the front. Therefore, the running resistance can be further reduced and the generation of wind noise can be further suppressed. Then, in the present embodiment, the locking projection 25 and the locking hole 26a that regulate the displacement of the traveling wind guide portion 14b in the substantially horizontal direction are arranged in the vicinity of the front end portion 14b-e of the traveling wind guide portion 14b. Therefore, the misalignment of the sharp portion of the traveling wind guide portion 14b, which is easily visible from the outside, can be efficiently regulated by the locking projection 25 and the locking hole 26a. Further, in general, in resin molding, it is difficult to obtain molding accuracy for a long and slender shape having a sharp tip such as a running wind guide portion 14b, but even if the upper cover 14U and the lower cover 14L try to separate in the vertical direction after assembly due to a reaction force due to a molding error. , The locking projection 25 effectively regulates the misalignment.

Further, in the door mirror 10 of the present embodiment, the plate-shaped piece 26 extending in a substantially horizontal direction is connected to the inner surface of the traveling wind guide portion 14b of the lower cover 14L, and the plate-shaped piece 26 and the inner surface are connected to prevent the plate-shaped piece 26 from falling. A locking rib 27 is projected so as to be regulated, and a locking hole 26a into which the locking projection 25 is fitted is formed in the plate-shaped piece 26. Therefore, the locking hole 26a can be sufficiently brought close to the support block portion 13A of the mirror base 13 without causing a decrease in the support rigidity of the plate-shaped piece 26. Therefore, when this configuration is adopted, the positional deviation between the upper cover 14U and the lower cover 14L in the traveling wind guide portion 14b can be regulated with high rigidity.

Further, in the case of the door mirror 10 of the present embodiment, the support piece 28 extending toward the front side is extended at the front end portion of the support block portion 13A, and the locking projection 25 on the upper cover 14U side is fitted. The hole 29 is formed in the vicinity of the end portion of the support piece 28 in the extending direction. Therefore, the overall size and weight of the support block portion 13A can be reduced as compared with the case where the entire width of the support block portion 13A is extended forward. Therefore, when this configuration is adopted, the through hole 29 can be provided in the support block portion 13A without causing the support block portion 13A to become large and heavy.

The present invention is not limited to the above embodiment, and various design changes can be made without departing from the gist thereof. For example, in the above embodiment, the upper cover 14U is provided with a locking projection 25 projecting downward, and the lower cover 14L side is provided with a locking hole 26a (locking portion) into which the locking projection 25 is fitted. However, conversely, a locking projection 25 projecting upward may be provided on the lower cover 14L side, and a locking hole 26a into which the locking projection 25 may be fitted may be provided on the upper cover 14U side.
