Vehicle mirror surface angle adjusting device, and vehicle mirror device
The present invention includes a stationary member, a movable member, a holding member, and a driving member. The stationary member has a stationary-side spherical surface. The movable member has a movable-side spherical surface. The stationary-side spherical surface and the movable-side spherical surface together forms a gap. The stationary-side spherical surface and the movable-side spherical surface are interposed with a sealant, which seals the gap. Consequently, the present invention allows smooth adjustment of an angle of a mirror surface, and prevention of water penetrating inside.
1. A vehicle mirror surface angle adjusting device that adjusts an angle of a mirror surface of a vehicle, the vehicle mirror surface angle adjusting device comprising:
a stationary member fixed to a mirror housing,
a movable member to be attached with a mirror unit,
a holding member holding the movable member onto the stationary member and rotatably centering a rotational center, and
a driving member allowing the movable member to rotate relative to the stationary member along with centering the rotational center,
wherein the stationary member has a stationary-side spherical surface configured of a part of the spherical surface that centers the rotational center,
the movable member has a movable-side spherical surface configured of a part of the spherical surface that centers the rotational center, the movable-side spherical surface having a radius smaller than a radius of the stationary-side spherical surface,
the holding member rotatably holds the movable member onto the stationary member such that the movable-side spherical surface is out of contact with the stationary-side spherical surface so that a gap is formed between the stationary-side spherical surface and the movable-side spherical surface, and
at least one of the stationary-side spherical surface and the movable-side spherical surface includes thereon a sealant pool part of a sealant, the sealant pool part including a circumferential groove part that is disposed continuously over an entire circumference centering a centerline which passes through the rotational center and intersects the mirror surface, and the sealant being applied seamlessly over the entire circumference of the circumferential groove part to seal the gap.
2. The vehicle mirror surface angle adjusting device according to claim 1 , wherein the sealant pool part includes a longitudinal groove part disposed in the direction intersecting the mirror surface.
3. The vehicle mirror surface angle adjusting device according to claim 2 , wherein the circumferential groove part and the longitudinal groove part have no mutual intersection when the mirror surface is in neutral or in initial settings.
4. The vehicle mirror surface angle adjusting device according to claim 2 , wherein the longitudinal groove part has a shape with a width narrower toward the mirror surface.
5. A vehicle mirror device comprising:
the vehicle mirror surface angle adjusting device according to claim 1 ,
a mirror housing fixed with the stationary member, and
a mirror unit attached to the movable member.
