In this example, the cover <NUM> is composed of molded resin. As shown in <FIG>, the cover <NUM> is attached to a downward portion of the fixing part <NUM> of the base <NUM> and a downward portion of the attaching part <NUM> with an attachment means (not shown) to cover the downward portion of the fixing part <NUM> and the downward portion of the attaching part <NUM>. Means such as mating means or elastic mating means can be employed as the attachment means as appropriate.

The cover <NUM> has a peripheral edge part <NUM>.

As shown in <FIG>, stopper parts <NUM> and <NUM> are provided at the edge part <NUM> at the downward portion of the base <NUM> and the vertical edge part <NUM> of the cover <NUM>, respectively. The stopper parts <NUM> and <NUM> restrict the vertical edge part <NUM> of the cover <NUM> from moving with respect to the edge part <NUM> at the downward portion of the base <NUM> by action of the horizontal edge part <NUM> of the gasket <NUM>. In an event when the vertical edge part <NUM> of the cover <NUM> moves with respect to the edge part <NUM> at the downward portion of the base <NUM>, the vertical edge part <NUM> may include the edge part <NUM> and the concave part <NUM>.

The plate part <NUM> and the additional plate part <NUM> are made thinner to prevent cracking during molding. On the other hand, the plate part <NUM> and the additional plate part <NUM> are made thicker at the peripheral edge potions than at the center portions to improve strength. As a result, the abutting edge part <NUM> can obtain sufficient strength even if a dimension in an abutting direction (solid arrow direction in <FIG>) is reduced.

The abutting edge part <NUM> and the abutting protrusion part <NUM> are in contact with each other, so that the vertical edge part <NUM> can be restricted from moving in a direction away from the edge part <NUM> (in a direction of a backward solid arrow in <FIG>) by action of the horizontal edge part <NUM>. The additional abutting edge part <NUM> and the additional abutting protrusion part <NUM> are in contact with each other, so that the vertical edge part <NUM> can be restricted from moving in a direction close to the edge part <NUM> (in a direction of the backward broken line arrow in <FIG>).

Description of assembling Base assembly <NUM> into Door mirror <NUM> Assembling the base assembly <NUM> into the door mirror <NUM> is described below.

First, the cover <NUM> is attached to the downward portion of the fixing part <NUM> and the downward portion of the attaching part <NUM> of the base <NUM> by attachment means. This allows the downward portion of the fixing part <NUM> and the downward portion of the attaching part <NUM> to be covered by the cover <NUM>.

Here, as shown in <FIG>, the abutting protrusion part <NUM> is inserted into the opening <NUM> to bring the abutting protrusion part <NUM> into contact with the abutting edge part <NUM> each other. Furthermore, the additional abutting edge part <NUM> is faced to the additional abutting protrusion part <NUM>. On the other hand, the abutting edge part <NUM> is abutted to the abutting protrusion part <NUM>. Furthermore, the additional abutting edge part <NUM> is faced to the additional abutting protrusion part <NUM>.

Next, the gasket <NUM> is attached to the fixing part <NUM> of the base <NUM> by the attaching means. This allows the base assembly <NUM> to be assembled.

During a handling step of the assembled base assembly <NUM>, there is a case where the vertical edge part <NUM> of the cover <NUM> is subject to force in a direction to separate the vertical edge part <NUM> away from the edge part <NUM> of the base <NUM> (solid arrow direction in <FIG>), or force in a direction to bring the vertical edge part <NUM> closer to the edge part <NUM> of the base <NUM> (dashed arrow direction in <FIG>).

In this case, since the abutting edge part <NUM> and the abutting protrusion part <NUM> are abutted to each other as well as the abutting edge part <NUM> and the abutting protrusion part <NUM> are abutted to each other, even if the vertical edge part <NUM> of the cover <NUM> is subjected to the force in the direction to separate the vertical edge part <NUM> away from the edge part <NUM> of the base <NUM> as mentioned above, it is possible to prevent the vertical edge part <NUM> from separating away from the edge part <NUM> of the base <NUM> and thus being lifted or fallen.

In addition, since the additional abutting edge part <NUM> and the additional abutting protrusion part <NUM> mutually face each other as well as the additional abutting edge part <NUM> and the additional abutting protrusion part <NUM> mutually face each other, even if the vertical edge part <NUM> of the cover <NUM> is subjected to the above mentioned force in the direction to bring the vertical edge part <NUM> closer to the edge part <NUM> of the base <NUM>, it is possible to prevent the vertical edge part <NUM> from getting close to the edge part <NUM> of the base <NUM> or being deformed.

Then, the monitoring assembly <NUM> is attached on an upstream portion of the attaching part <NUM> of the base <NUM> of the base assembly <NUM> whose assembly is completed, rotatably around the rotation center axis line O by the electric holding unit. This allows the door mirror <NUM> to be assembled.

Then, the fixing part <NUM> of the base <NUM> of the door mirror <NUM> is fixed to the outer panel <NUM> of the door of a vehicle by fixing means. Thereby, the door mirror <NUM> is equipped on the vehicle. At this time, as shown in <FIG>, the gasket <NUM> exists between the fixing part <NUM> of the base <NUM> and the outer panel <NUM>.

Here, the gasket <NUM> is subjected to various forces during existing between the fixing part <NUM> of the base <NUM> and the outer panel <NUM>. Thereby, the horizontal edge part <NUM> of the gasket <NUM> may be forced to press against the vertical edge part <NUM> of the cover <NUM>. Accordingly, the vertical edge part <NUM> of the cover <NUM> is subjected to force in a direction to separate the vertical edge part <NUM> away from the edge part <NUM> of the base <NUM> (solid arrow direction in <FIG>).

Even if the vertical edge part <NUM> of the cover <NUM> is subjected to the above mentioned force to separate, as described above, since the abutting edge part <NUM> and the abutting protrusion part <NUM> are abutted to each other as well as the abutting edge part <NUM> and the abutting protrusion part <NUM> are abutted to each other, it is possible to prevent the vertical edge part <NUM> from separating from the edge part <NUM> of the base <NUM> and thus being lifted or fallen.

The base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment are configured as mentioned above. A working and effect thereof are described below.

The base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment includes stopper parts <NUM> and <NUM> to restrict the vertical edge part <NUM>(which may include the edge part <NUM> and the concave part <NUM>) from moving with respect to the edge part <NUM> at the downward portion of the base <NUM> by action of the horizontal edge part <NUM> of the gasket <NUM>, wherein the stopper parts <NUM> and <NUM> are provided on the edge part <NUM> at the downward portion of the base <NUM> and the vertical edge part <NUM> of the cover <NUM>, respectively. As a result, the base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment can restrict the vertical edge part <NUM> of the cover <NUM> from moving with respect to the base <NUM>. This allows the base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment to prevent the vertical edge part <NUM> of the cover <NUM> from being lifted, fallen, or deformed.

The base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> in this embodiment have stopper parts <NUM>, 7B, 7F on the base <NUM> side in the vertical direction and stopper parts <NUM>, 8B, 8F on the cover <NUM> side in the horizontal direction. Consequently, as shown in <FIG>, the base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment can have dimensions T1 and T3 between the edge part <NUM> of the base <NUM> and the vertical edge part <NUM> of the cover <NUM> larger than dimensions T2 and T4 in the case where the present invention is not carried out (see <FIG>).

This allows the base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment to have increased dimensions T1 and T3 between the edge part <NUM> of the base <NUM> and the vertical edge part <NUM> of the cover <NUM>, so that flexibility of design shape of the base assembly <NUM>, flexibility of design shape of the periphery monitoring device for a vehicle <NUM>, and flexibility of design shape of the outer panel <NUM> can be increased.

The case where the present invention is not carried out (hereinafter referred to as "comparative example") is explained below with reference to <FIG>. Among <FIG>, <FIG>, the same reference numeral or reference symbol denotes the same component.

In the comparative example, stopper parts 70B and 70F on a base <NUM>'s side are provided in a vertical direction, and the stopper parts 80B and 80F on a cover <NUM>'s side are also provided in the vertical direction. As a result, in the comparative example, it is necessary to reduce dimensions T2 and T4 between the edge part <NUM> of the base <NUM> and the vertical edge part <NUM> of the cover <NUM> due to shaping constraint of the edge part <NUM> of the base <NUM> and the vertical edge part <NUM> of the cover <NUM> as well as molding mold constraint of the base <NUM> and the cover <NUM>.

Consequently, as shown in <FIG>, the comparative example has dimensions T2 and T4 between the edge part <NUM> of the base <NUM> and the vertical edge part <NUM> of the cover <NUM> smaller than dimensions T1 and T3 of the base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment (see <FIG>).

To the contrary, as shown in <FIG>, in the base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment, the stopper parts <NUM>, 7B, and 7F on the base <NUM>'s side are provided in the vertical direction, as well as the stopper parts <NUM>, 8B, and 8F on the cover <NUM>'s side are provided in the horizontal direction. As a result, in the base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment, it is possible to increase dimensions T1 and T3 between the edge part <NUM> of the base <NUM> and the vertical edge part <NUM> of the cover <NUM> without shaping constraint of the edge part <NUM> of the base <NUM> and the vertical edge part <NUM> of the cover <NUM> as well as molding mold constraint of the base <NUM> and the cover <NUM>.

In the base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment, the cover <NUM> is provided continuously at the vertical edge part <NUM> and has a concave part <NUM> which is concaved from the vertical edge part <NUM>'s side to the downward portion of the base <NUM> and to the downward portion of the gasket <NUM>. As a result, the base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment can increase flexibility of design shape of the vertical edge part <NUM> of the cover <NUM>.

Furthermore, in the base assembly <NUM> and the periphery monitoring device for a vehicle <NUM> according to the present embodiment, the concave part <NUM> is even formed at the vertical edge part <NUM> of the cover <NUM>. Nevertheless, it is possible to restrict the vertical edge part <NUM> of the cover <NUM> from moving with respect to the base <NUM> by means of the stopper parts <NUM>, 7B, and 7F provided in the vertical direction on the base <NUM>'s side and the stopper parts <NUM>, 8B, and 8F provided in the horizontal direction on the cover <NUM>'s side.
