PROBLEM TO BE SOLVED: To provide a small-sized angle adjustment mechanism that can prevent reduction in accuracy of assembly or parts and make power consumption.SOLUTION: According to the present application, an angle adjustment mechanism 300 is provided which adjusts the rotation angle of a mirror 200 having a concave mirror 210 rotatably supported on a bracket 100 with a first rotational axis 201. The angle adjustment mechanism 300 includes: a motor 320; a speed reduction mechanism 330 connected to the motor 320; and an arm 340 swingably supported in a case 310 with a second rotational axis 342 and connected to the speed reduction mechanism 330 and engaged with an engaging part 245 of a frame 220 of the mirror 200 to rotate the mirror 200. By arranging the angle adjustment mechanism 300 within the width of the concave mirror 210, a mirror unit 4 can have a small size.SELECTED DRAWING: Figure 9

    【課題】小型化とともに組み立て精度や部品精度を抑えることができ、省電力が図られる角度調整機構を提供する。【解決手段】ブラケット100に第1の回転軸201を介して回転可能に支持された凹面鏡210を有するミラー200を回転させて該ミラー200の回転角度を調整する角度調整機構300であって、モータ320と、モータ320に接続された減速機構330と、ケース310内に第2の回転軸342を介して揺動可能に支持されるとともに減速機構330に接続され、ミラー200のフレーム220の係合部245に係合してミラー200を回転させるアーム340とを備えたものとする。角度調整機構300を凹面鏡210の幅内に配設することによってミラーユニット4の小型化を可能とする。【選択図】図9
