  However, the driver's side mirror has a cab blind spot area Y that extends obliquely rearward from the position closest to the driver's seat side door, and thus the driver's view cannot be secured in some cases. Further, although it is conceivable to dispose the driver's seat side under mirror in the vicinity of the driver's seat side mirror to eliminate the cab blind spot area Y, there is a case where a sufficient field of view cannot be secured.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle side mirror structure that ensures a driver's field of view.

The present invention includes a driver-side side mirror and a driver-side under mirror positioned below the driver-side side mirror, and obliquely rearward from a position closest to the driver-side door that cannot be visually recognized by the driver-side side mirror. The vehicle side mirror structure for visually confirming the cab blind spot area extending to the driver side under mirror,
The driver side under mirror is disposed below and in front of the driver's eyes, and
When a recognition pole having a diameter of 300 mm and a height of 1000 mm is arranged in a blind spot area that cannot be visually recognized by the driver's seat side undermirror body itself, the position and size at which at least a part of the recognition pole can be visually confirmed Configure the under mirror ,
The driver seat side under mirror is attached to the stay that supports the driver seat side mirror, and the stay is inclined upward so that the mounting position below the stay is close to the waistline of the door. is there.

  Thus, in this way, the driver's seat under mirror is arranged below the driver's seat side mirror, and the cab blind spot area that extends obliquely rearward from the position closest to the driver's seat side door that cannot be seen with the driver's seat side mirror. Can be visually recognized. In addition, the driver side under mirror is disposed below and in front of the driver's eyes, and the blind area in front of the vehicle that cannot be visually recognized by the driver side under mirror body itself has a diameter of 300 mm. The position and size of the driver side under mirror are set so that at least part of the recognition pole can be visually recognized when a 1000 mm high recognition pole is placed. A visual field can be appropriately secured for the blind spot area. Here, the size of the recognition pole in this case is a target for visual recognition in accordance with security standards (for example, Article 44), that is, a size assuming an infant or the like. Therefore, if at least a part of the recognition pole can be visually recognized, the infant can be visually recognized, and appropriate visibility can be obtained.

  Further, in the present invention, it is preferable to provide a gap between the driver side under mirror body and the vehicle structure so that the driver side under mirror body itself does not overlap the vehicle structure. Since the blind spot area by the driver's seat side under mirror body itself does not overlap with the blind spot area by the vehicle structure, the field of view can be suitably secured.

In the present invention, when attaching the driver side under mirror stay which supports the driver's side outside mirror, a stay for supporting the driver's side outside mirror, since commonality of the stay attaching the driver side under the mirror , Can reduce the number of stays and secure a field of view. In addition, since a complicatedly configured stay is not required, the appearance can be improved and the manufacturing cost can be reduced.

In the present invention, as close to the mounting position of the stay below the waist line of the door, when constituted by inclined stays upward, the mounting position of the stay lower, close to the high rigidity waistline, a stay lower The mounting strength of the door mounting portion can be ensured, and the driver seat side under mirror can be provided at a low position that increases the degree of freedom in arrangement in the height direction and does not obstruct the field of view.

  Further, in the present invention, the driver side mirror that is held by a single mirror body is divided into two upper and lower stages, the upper side is a sub-mirror of a mirror corresponding to a plane, and the lower side is a main mirror that is a curved mirror. In this case, the upper side sub-mirror is a plane-equivalent mirror, so that the image of the vehicle or the like is not distorted in the cab blind spot area that extends relatively rearward from the vehicle side than the driver. This makes it easy to check and can accurately recognize the sense of distance, making it suitable for use on highways. The main mirror of the lower curved mirror can secure a field of view extending from the side of the vehicle to the rear, and is suitable for traveling on a general road. By providing a driver side under mirror that mainly secures a field of view near the cab such as an intersection, a mirror structure corresponding to the traveling state can be provided, and the burden on the driver can be reduced.

  According to the vehicle side mirror structure of the present invention described above, the cab blind spot region extending obliquely rearward from the position closest to the driver side door can be sufficiently visually recognized by the driver side under mirror. In addition, when a recognition pole having a diameter of 300 mm and a height of 1000 mm is arranged in a blind spot area by the driver's seat side undermirror body itself, at least a part of the recognition pole can be visually recognized at a position and size. Therefore, it is possible to obtain various excellent effects that the field of view can be secured even in the blind spot area by the driver seat side under mirror body itself.
