Vehicle outside mirror device
View Patent ↗A vehicle outside mirror device according to the present invention is provided with a base 2 , a shaft 3 , a spring 10 , a mirror assembly 4 , and a washer 6 . An annular line contact portion 50 is provided on an abutment face 35 of the washer 6 that abuts against an abutment face 33 of a mount portion 12 of the mirror assembly 4 . As a result, the vehicle outside mirror device according to the present invention can prevent generation of abnormal noise further reliably and a further long period of time by means of the annular line contact portion 50 . In addition, an abutment plane 301 of a rotation stop portion is provided at a shaft 3 . A linear edge 601 of the rotation stop portion is provided at the washer 6 . As a result, according to the vehicle outside mirror device of the present invention, the linear edge 601 of the rotation stop portion of the washer 6 is abutted against the abutment plane 301 of the rotation stop portion of the shaft 3 , whereby the washer 6 is fixed to the shaft 3 and then generation of abnormal noise can be prevented further reliably and over a further long period.
1. A vehicle outside mirror device, enabling a mirror assembly to tilt relative to a vehicle body, said device comprising:
a base which is fixed to the vehicle body;
a shaft which is fixed to the base;
a spring which is disposed in a state in which the spring is compressed at a periphery of the shaft;
the mirror assembly which has an abutment face and is equipped to be able to tilt relative to the shaft; and
a washer which has an abutment face and is disposed on the periphery of the shaft and is abutted against the mirror assembly by means of the spring, wherein axially extending apexes form an annular line contact portion, which apexes are provided on at least either one of the abutment face of the mirror assembly and the abutment face of the washer, a respective one of the abutment face of the mirror assembly and the abutment face of the washer abut against an other of the abutment face of the mirror assembly and an abutment face of the washer.
2. The vehicle outside mirror device according to claim 1 , wherein
the annular line contact portion is provided on a face of the washer, which abuts against the mirror assembly of the washer, and a face of the washer opposite to the face abutting against the mirror assembly.
3. The vehicle outside mirror device according to claim 1 , wherein
a surface-textured surface is provided on at least one of the abutment face of the mirror assembly and the abutment face of the washer.
4. The vehicle outside mirror device according to claim 1 , wherein:
a rotation stop portion for stopping the washer from rotating around a rotational center of the shaft, is provided at a respective one of the shaft and the washer; and
the washer is mounted on the shaft so as to disable rotation around the rotational center of the shaft by means of the rotation stop portion.
