Description

  The present invention relates to an automobile sun visor, and more particularly to an automobile sun visor provided between a front pillar and a rearview mirror so as to be rotatable in the vertical direction as a sunshade at a front end position of a ceiling portion in the vehicle.

  As a conventional automobile sun visor, a structure is known in which a plate-like visor body is disposed at a front end position of a vehicle interior ceiling so as to be rotatable in the vertical (front-rear) direction (see, for example, Patent Document 1).

  Generally, a conventional automobile sun visor has a visor body 101 provided between a front pillar garnish 102 and a room mirror 103 as shown in FIG. The visor body 101 is attached to the body portion of the mounting shaft 104 so as to be vertically rotatable, and further, by fixing the one end portion 104a side of the mounting shaft 104 to the front end portion of the vehicle interior ceiling portion 106 via the bracket 105, It is attached to the front end of the interior ceiling 106.

  The visor main body 101 is provided with a knob exposed portion 108 that exposes a knob 107 that encloses a wire (not shown). Normally, the knob 107 exposed at the knob exposed portion 108 is detachably engaged with a locking hook 109 provided at the front end portion of the vehicle interior ceiling portion 106, and the visor body 101 is attached to the mounting shaft 104. A structure is employed in which the hooking hook 109 is held at the front end of the interior ceiling 106 at two points.

  The visor body 101 configured as described above can be rotated in the front-rear (vertical) direction with the mounting shaft 104 and the locking hook 109 as fulcrums at the front end of the interior ceiling 106, that is, on the windshield side. Also, when the knob 107 and the locking hook 109 are disengaged, the mounting shaft 104 is horizontally rotated in the vehicle width direction with the bracket 105 as a fulcrum, and the visor body 101 is moved to the side edge of the vehicle interior ceiling. It can be arranged.

  By the way, in this type of vehicle sun visor, there is a risk that the visor body 101 and the room mirror 103 may collide with each other due to the movement of the visor body 101 in the front-rear (up and down) direction or the movement of adjusting the angle of the room mirror 103. Further, there is a possibility that the visor body 101 and the front pillar garnish 102 interfere with each other when the vehicle is traveling. In order to eliminate this, normally, a gap S1 of about 10 mm is provided between the visor body 101 and the rear mirror 103, and a gap S2 of at least about 5 mm is provided between the visor body 101 and the front pillar garnish 102.
