Description

  The present invention relates to a vehicle mirror device in which a seal portion seals a gap between a vehicle body side and a covering member.

  In the door mirror described in Patent Document 1 below, a base is attached to a vehicle body door panel, and the base is covered with a base cover. Furthermore, the vehicle body door panel side of the base cover is sealed with packing.

  Here, in such a door mirror, there is a door mirror in which an extending portion is integrally formed on the entire outer periphery of the packing, and the extending portion seals a gap between the vehicle body door panel and the base cover.

  In this case, the extending portion extends in the direction toward the inner peripheral side of the packing as it goes from the packing toward the vehicle body door panel. For this reason, particularly when the gap between the vehicle body door panel and the base cover is small, the end of the extending portion on the vehicle body door panel side is greatly separated from the outer periphery of the base cover to the inner peripheral side. As a result, the base cover appears to float with respect to the vehicle body door panel, and the gap between the vehicle body door panel and the base cover does not look good.

When the contact position of the base 16 with the bent portion 30 of the contact cylinder 16A is displaced, the displacement of the contact position with the lower end of the seal portion 32 of the door panel 12A is suppressed or prevented.

  As a result, even if the dimension of the gap 22 between the lower end of the base cover 20 and the door panel 12A varies, the lower end of the seal portion 32 can be further prevented from separating from the outer periphery to the inner peripheral side of the base cover 20, and the door panel It is possible to further suppress the base cover 20 from appearing to float with respect to 12A, and to further improve the appearance of the gap 22 between the lower end of the base cover 20 and the door panel 12A.

  Further, the drain hole 35 of the gasket 28 is disposed at the lower end of the gasket 28. Even if water or the like enters the gasket 28 through the gap 22 between the lower end of the base cover 20 and the door panel 12A, The water or the like is discharged to the outside of the gasket 28 through the drain hole 35.

  Here, the drain hole 35 is closed all around. For this reason, unlike the case where the drain hole 35 is opened to the outside of the outer periphery of the gasket 28, it is possible to suppress the occurrence of a so-called crease in the drain hole 35 forming portion of the seal portion 32, and the drain hole 35 of the seal portion 32. The formation portion can be prevented from being exposed to the outer periphery outside the lower end of the base cover 20, and the appearance of the gap 22 between the lower end of the base cover 20 and the door panel 12A can be improved.

  In the present embodiment, one bent portion 34 is provided in the gasket 28. However, a plurality of flexible portions 34 may be provided on the gasket 28.

  Furthermore, in this embodiment, the bent portion 34 of the gasket 28 has a U-shaped cross section. However, the bent portion 34 of the gasket 28 may have a shape other than a U-shaped cross section (for example, a V-shaped cross section).

  In the present embodiment, the bent portion 34 of the gasket 28 is protruded downward (door panel 12A side). However, the bent portion 34 of the gasket 28 may be protruded upward (base cover 20 side).

  Further, in the present embodiment, the contact cylinder 16 </ b> A of the base 16 is brought into contact with the bent portion 30 of the gasket 28. However, the abutting cylinder 16 </ b> A of the base 16 does not have to abut on the bent portion 30 of the gasket 28.

  In the present embodiment, the vehicle mirror device of the present invention is applied to the vehicle door mirror device 10. However, the vehicle mirror device of the present invention may be applied to another vehicle outer mirror device (for example, a vehicle fender mirror device) outside the vehicle or a vehicle inner mirror device inside the vehicle.
