  Generally, there are variations in dimensions in the above-mentioned substrate member, door mirror mounting portion, and seal member, and there is also an installation error when the substrate member is mounted on the door mirror mounting portion with the seal member in between. When a board | substrate member is attached to a door mirror attaching part on both sides of a sealing member, the space | interval of a board | substrate member and a door mirror attaching part may vary for every vehicle.

Thereby, for example, when the interval between the substrate member and the door mirror attachment portion is smaller than a predetermined value, the seal lip portion of the seal member is pressed to the door mirror attachment portion by a predetermined amount or more by the pressing portion of the substrate member. There is a possibility that the sealing performance of the seal lip portion of the seal member is lowered. Conversely, for example, when the distance between the substrate member and the door mirror mounting portion is larger than a predetermined value, the sealing lip portion of the sealing member is not properly pressed against the door mirror mounting portion by the pressing portion of the substrate member. The packing needs to be sandwiched between the seal lip portion and the door mirror mounting portion.
In the vehicle door mirror mounting structure according to the present invention, when the substrate member is mounted on the door mirror mounting portion with the seal member interposed therebetween, the sealing lip portion of the sealing member is appropriately pressed against the door mirror mounting portion by the pressing portion of the substrate member. It is intended to be configured as follows.

[I]
(Constitution)
A feature of the present invention resides in the following configuration in the vehicle door mirror mounting structure.
A substrate member in a door mirror, a door mirror attachment portion to which the substrate member is attached, and a seal member disposed between the substrate member and the door mirror attachment portion, on the door mirror attachment portion side of the seal member, on the door mirror attachment portion side A protruding seal lip portion is provided, and a flexible portion is provided at a portion different from the seal lip portion in the seal member and adjacent to the seal lip portion. In a state where the substrate member is attached to the door mirror attachment portion with the seal member interposed therebetween, the portion of the seal member on the side opposite to the deflection portion with respect to the seal lip portion is the substrate member side portion, and the pressing portion of the substrate member is the door mirror It is configured to press against the mounting portion side.

(Function)
According to the feature of the present invention, in a state where the substrate member is attached to the door mirror attaching portion with the seal member interposed therebetween, the portion on the substrate member side of the seal member on the opposite side to the flexible portion with respect to the seal lip portion is provided. The pressing part of the substrate member presses the door mirror mounting part side.
Thereby, for example, when the distance between the substrate member and the door mirror mounting portion becomes smaller than a predetermined value, according to the feature of the present invention, the seal lip portion of the seal member is pressed against the door mirror mounting portion by a predetermined amount or more by the pressing portion of the substrate member. Even if it is going to be done, it will be in the state where the sealing lip part of a sealing member will escape from the press part of a substrate member because the flexible part of a sealing member will bend, and the sealing lip part of a sealing member will be in a door mirror attachment part by the pressing part of a substrate member A state where the pressure is pressed more than a predetermined amount is avoided.

If the state where the seal lip portion of the seal member escapes from the pressing portion of the substrate member can be obtained by the deflection of the seal member as in the feature of the present invention, the seal lip portion of the seal member is relatively Can be set to long (tall). As a result, for example, when the distance between the substrate member and the door mirror mounting portion becomes smaller than a predetermined value, the flexible portion of the seal member bends as described above, so that the seal lip portion of the seal member is moved by the pressing portion of the substrate member. A state where the mounting portion is pressed more than a predetermined amount is avoided.
If the seal lip portion of the seal member can be set to be relatively long (tall) like the feature of the present invention, for example, when the distance between the substrate member and the door mirror mounting portion is larger than a predetermined value. However, the seal lip portion of the seal member can come into contact with the door mirror mounting portion, and the seal lip portion of the seal member can be appropriately pressed against the door mirror mounting portion by the pressing portion of the substrate member.

  As described above, according to the feature of the present invention, in a state where the substrate member is attached to the door mirror attaching portion with the seal member interposed therebetween, the distance between the substrate member and the door mirror attaching portion is large even if it is smaller than a predetermined value. Even so, the seal lip portion of the seal member can be appropriately pressed against the door mirror mounting portion by the pressing portion of the substrate member, so that packing is provided between the seal lip portion of the seal member and the door mirror mounting portion. There is no need to pinch (e.g., even if packing is used, it is only necessary to use low-level and simple packing, or only partially use packing where necessary).

(The invention's effect)
According to the characteristics of the present invention, in the vehicle door mirror mounting structure, when the substrate member is mounted on the door mirror mounting portion with the seal member interposed therebetween, for example, even if the interval between the substrate member and the door mirror mounting portion is smaller than a predetermined value. Even if it becomes larger, the sealing lip portion of the sealing member can be appropriately pressed against the door mirror mounting portion by the pressing portion of the substrate member, and the sill property of the sealing member can be improved, so that I was able to reduce the entry of.

  According to the feature of the present invention, it is not necessary to sandwich the seal between the seal lip portion of the seal member and the door mirror mounting portion (for example, even if the packing is used, it is possible to use a lower and simple packing, Therefore, it is advantageous in terms of simplifying the production process and reducing production costs.

  According to the feature of the present invention, the seal lip portion of the seal member is appropriately pressed against the door mirror mounting portion by the pressing portion of the substrate member, so that the seal lip portion of the seal member is not properly pressed against the door mirror mounting portion. As a result, it is possible to avoid deformation of the seal member due to the above, lifting from the door mirror mounting portion, and the like, so that the appearance of the door mirror and the seal member can be improved.
