PROBLEM TO BE SOLVED: To provide a display position adjustment unit that exhibits stable performance together with high design freedom and quietness.SOLUTION: A drive source 36 includes an output shaft 381 connected to a first shaft part 331, out of the revolving shaft 33 of a reflector 32, that projects in a specific X direction. A bearing body 34 comprises a holding base 341 that holds the drive source 36 and a bearing base 342 that bears, by a recess dented in a specific X direction, a second shaft part 332, out of the revolving shaft 33, that projects in a direction opposite the specific X direction. As the revolving shaft 33 rotates from an initial rotation position R0 at which a restoring force becomes minimal under a use state, an elastic member 39 is deformed by tension between the reflector 32 and the bearing body 34 and the restoring force increases. As the line of action Lf of the restoring force is inclined to all of the specific X direction, specific Y direction and specific Z direction at the initial rotation position R0, a state arises in which the elastic member 39 urges the revolving shaft 33 in each of the specific X direction, specific Y direction and specific Z direction.SELECTED DRAWING: Figure 3

    【課題】高い設計自由度及び静粛性と共に安定性能を発揮する表示位置調整ユニットの提供。【解決手段】駆動源36は、反射鏡32の回転軸33のうち、特定X方向に突出している第一軸部331に対して連結されている出力軸381を有する。軸受体34は、駆動源36を保持している保持ベース341と、回転軸33のうち、特定X方向とは逆方向に突出している第二軸部332を、特定Z方向に凹む凹部により軸受している軸受ベース342とを有する。復原力が使用状態下での最小となる初期回転位置R0から回転軸33が回転するに従い、弾性部材39が反射鏡32と軸受体34との間にて引張り変形することで、復原力は増大する。初期回転位置R0において、復原力の作用線Lfが特定X方向と特定Y方向と特定Z方向との全てに対して傾斜することで、弾性部材39が特定X方向と特定Y方向と特定Z方向とのそれぞれに回転軸33を付勢した状態となる。【選択図】図3
