PROBLEM TO BE SOLVED: To provide a vehicular head-up display device capable of accurately calculating a reference position while reducing torque to be given to a stopper mechanism when moving a reflection part to a stop position, and capable of reducing generation of sound at the time of stop by the stopper mechanism.SOLUTION: In the vehicular head-up display device, a reflection part 132 is rotatable within a rotatable range that is less than one rotation, and a terminal position of the rotatable range becomes the stop position where the reflection part 132 is forcibly stopped by the stopper mechanism. When forcibly stopping the reflection part 132 from a predetermined rotation position to the stop position, a control device 150 executes stop control by which a step motor 133 is temporarily rotated just for predetermined rotations reversely to a direction toward the stop position and a rotation command corresponding to the rotatable range in the direction toward the stop position is given to the step motor 133 thereafter.SELECTED DRAWING: Figure 1

    【課題】反射部を停止位置に移動させる際に、ストッパ機構に与えるトルクを低減して基準位置を正確に出すと共に、ストッパ機構による停止時の音の発生を低下することのできる車両用ヘッドアップディスプレイ装置を提供する。【解決手段】車両用ヘッドアップディスプレイ装置において、反射部132は、1回転未満となる回転可能範囲で回転可能となっており、回転可能範囲の終点位置は、ストッパ機構によって反射部132が強制的に停止される停止位置となっており、制御装置150は、反射部132を所定の回転位置から停止位置に強制停止させる際に、一旦、停止位置に向かう方向とは逆方向に所定回転分だけステップモータ133を回転させ、その後に、停止位置に向かう方向に回転可能範囲分に相当する回転指令をステップモータ133に与える停止制御を実行する。【選択図】図1
