Abstract

In a vehicle door mirror device, a through hole of a case is penetrated by a support shaft so as to rotatably support the case on the support shaft. Lower ribs are formed in a protruding state at a peripheral face of the through hole, and protrusion leading end faces of the lower ribs are capable of contacting the support shaft. A gap dimension between the peripheral face of the through hole and the support shaft can accordingly be made small, thereby enabling rattling of the case with respect to the support shaft to be suppressed. Moreover, the contact surface area between the peripheral face of the through hole and the support shaft can be made small, thereby enabling an increase in sliding resistance between the peripheral face of the through hole and the support shaft to be suppressed.

First claim

What is claimed is:

1 . A vehicle visual recognition device comprising:
a support shaft that is supported at a vehicle body side; a rotation member that is provided with a through hole, and that is rotatably supported at the support shaft with the support shaft penetrating through the through hole; a protrusion portion that is protrudingly provided at a peripheral face of the through hole, and that is capable of contacting the support shaft; and a visual recognition section that is provided so as to be capable of rotating integrally with the rotation member, that assists a vehicle occupant with visual recognition, and that is stored or stands out by rotating of the rotation member.

2 . The vehicle visual recognition device of claim 1 , further comprising:
a restriction portion that is provided at the vehicle body side, a position of the restriction portion coinciding with a position of the protrusion portion in an axial direction of the support shaft; and a rotation portion that is provided at the rotation member, a position of the rotation portion coinciding with the position of the protrusion portion in the axial direction of the support shaft, and rotating of the rotation member being restricted by the rotation portion abutting the restriction portion.

3 . The vehicle visual recognition device of claim 1 , further comprising:
a restriction portion that is provided at the vehicle body side; and a rotation portion that is provided at the rotation member, rotating of the rotation member being restricted by the rotation portion abutting the restriction portion, wherein a position of a leading end face of the protrusion portion, that is capable of contacting the support shaft, coincides with a position of at least a part of an abutting area where the restriction portion abuts the rotation portion, in an axial direction of the support shaft.

4 . The vehicle visual recognition device of claim 2 , wherein a position of a leading end face of the protrusion portion, that is capable of contacting the support shaft, coincides with a position of at least a part of an abutting area where the restriction portion abuts the rotation portion, in the axial direction of the support shaft.

5 . The vehicle visual recognition device of claim 1 , wherein a plurality of protrusion portions, protruding toward a side of the support shaft, are provided at the peripheral face of the through hole along a peripheral direction of the support shaft, and respective leading end faces of the protrusion portions are capable of contacting the support shaft.

6 . The vehicle visual recognition device of claim 2 , wherein:
a plurality of protrusion portions, protruding toward a side of the support shaft, are provided at the peripheral face of the through hole along a peripheral direction of the support shaft, and respective leading end faces of the protrusion portions are capable of contacting the support shaft; and the restriction portion and the rotation portion are provided at positions further toward an outer side than positions of the plurality of protrusion portions in a radial direction of the support shaft, and rotating of the rotation member is restricted by an end portion in the peripheral direction of the restriction portion abutting an end portion in the peripheral direction of the rotation portion.
