Overview

Compared to being similarly rear-of-body mirrors, since the gaze of the vehicle is moved only when necessary, there is a feature that allows you to concentrate on driving, and the possibility of damage to the human body due to protrusions during a car-to-person accident is It becomes few. On the other hand, the dead angle increases and the problem of entanglement accidents occurs. Especially when viewing the left door mirror, you have to shift your line of sight from the front. Mirrorless vehicles with cameras and monitors conforming to the criteria were also available instead of mirrors since 2016. As a result, reduction of blind spots, reduction of air resistance and wind noise can be expected.

history

The world's first C32 type Laurel (early model type) equipped with an electric retractable door mirror as standard equipment

It was after the Second World War that the car became a form integrated with the body like the present (), there is no accessory to confirm the side before the mirror is attached to the fender However, due to the sales strategy in the UK in the 1950s some mirrors for motorcycles began to be attached to the beginning of the external mirror. At that time, imported, etc., started with importing Fender Mirror to Japan, the Fender Mirror is less blind spot than the Door mirror, and it is said that the driver's angle of movement is small because it is in front, and in Japan At the time of the law) (Article 44 (rear mirror etc.)), only Fender mirror was not allowed to wear. Naturally, the exchange from the fender mirror to the door mirror was also illegal. As a result, young people exchanging from fender mirrors to door mirrors due to trends often encountered crackdowns.

However, we received the indication that it is "from" the Japanese automobile industry outside Japan, the regulation was abolished in March 1988, and after that the door mirrors were installed in vehicles manufactured and sold in Japan It became possible.

Despite the disadvantage that there are many blind spots compared to the fender mirror, the door mirrors are the mainstream worldwide for reasons such as the safety at the time of interpersonal accident and design, and at that time the obligation to use Fender Mirror is restricted only to Japan , And after the elimination of regulation mainly from the design side, it shifted from the fender mirror to the door mirror almost. Initially the door mirrors were fitted immediately after the abolition of regulations in 1983 (1983).

In the following year (Showa 59), a type (electric retractable door mirrors) that the door mirrors store by electric power has appeared, it is easy to adjust the mirror on the passenger side, and the body of others is mirrored at a parking lot etc Since it was solved the inconvenience that the angle shifted, it was widely popular not only after that, but also in the world including the United States.

Initially it was only for senior passenger cars, but now it is also equipped with and etc. Depending on the type of car, there are things that only electric mirror adjustment can be done on the mirror surface, there is also a door mirror that carries out storage by hand with one touch. It is a mirror that can be stored electrically, and if it is forcibly stored with hands etc., there is also the possibility of damaging the internal parts, and it needs attention. In addition, for large trucks and other large-sized vehicles, only the left side mirror is electrically stored for many purposes in order to ensure safety at the time of departure after parking. Also, in the 2010 's, in conjunction with the door lock, unlocking and starting the ride engines, things that are stored simultaneously with deployment and locking also appeared.

There is a case that the door mirrors are built in (). There are lamp units that can be retrofitted even if they are not installed.

In sports cars and the like, things that care about air resistance are often used. Streamlined after parts called aerodynamics and the like are also popular, but they must conform to the criteria as things that are less likely to cause injuries to pedestrians, such as folding down type.
