Description

本発明のアクチュエータは、上記課題を解決するために、一の平面上に反射部が形成された可動部と、前記可動部を、回転軸を中心として揺動可能に、支持部に接続するトーションバーと、前記一の平面とは反対側の他の平面に形成され、前記可動部の平坦性を維持する一以上のリブと、を備え、前記一以上のリブに含まれる第１リブは、前記他の平面上の、前記反射部の外縁と前記トーションバーとの間に対応する領域に形成されており、前記第１リブの前記トーションバー側の側面は、前記他の平面上で平面的に見て、前記反射部側に凸となるように湾曲している。 The actuator of the present invention, in order to solve the above problems, a movable portion reflecting portion is formed on one plane, the movable portion swingably about an axis of rotation, is connected to the support portion torsion A bar and one or more ribs formed on another plane opposite to the one plane and maintaining the flatness of the movable part, and the first rib included in the one or more ribs includes: on the other flat surface, the is formed in a corresponding region between the outer edge of the reflective portion and the torsion bar, the side surface of said torsion bar side of the first rib on the said other flat surface In plan view, it is curved so as to be convex toward the reflecting portion.

Claims

A movable part having a reflective part formed on one plane;
The movable portion swingably about an axis of rotation, and a torsion bar connected to the support part,
One or more ribs formed on another plane opposite to the one plane and maintaining the flatness of the movable part;
With
First rib included in the one or more ribs, on the other flat surface, it is formed in a corresponding region between the outer edge and the torsion bar of the reflective portion,
Side of the torsion bar side of the first rib, in plan view of the other flat surface is curved to be convex to the reflective portion
Actuators.

The other when viewed in plan on the flat surface, the side surface of the torsion bar of the first rib, the actuator according to 請 Motomeko 1 Ru concave der in portions remote from the axis of rotation.

In plan view of the other flat surface, the side surface of the torsion bar of the first rib, according to 請 Motomeko 1 or 2 Ru convex der toward the torsion bar side in the rotation axis near Actuator.

Said movable part is in the vicinity of the connection portion between the torsion bar and the movable portion, as compared to the peripheral portion, along the other flat surface, it has a projecting portion projecting toward the outside of the movable portion ,
A portion of the first rib is the formed on the other flat surface on so as to extend over the protruding portion
The actuator according to any one of 請 Motomeko 1 to 3.

Wherein on the other plane, a region corresponding to a region where the reflecting portion is formed on said one plane, 請 Motomeko 1-4 second rib included in the one or more ribs that are formed The actuator according to any one of the above.
