To provide a mirror unit and a head-up display device capable of rotating a reflection part smoothly.SOLUTION: A mirror unit comprises: a concave mirror; a holder main body 36 rotatably supported with a rotation axis as a center, for holding the concave mirror; and an attachment member 38 formed in the holder main body 36 attachably and detachably and sandwiched by a slider part moving a Z direction crossing the rotation axis to rotate the holder main body 36 around the rotation axis with the movement of the slider part. The attachment member 38 is formed of material having lower friction coefficient than that of the holder main body 36.SELECTED DRAWING: Figure 6

    【課題】反射部をスムーズに回転させることができるミラーユニット及びヘッドアップディスプレイ装置を提供する。【解決手段】ミラーユニットは、凹面鏡と、回転軸を中心に回転可能に支持され、凹面鏡を保持するホルダ本体部36と、ホルダ本体部36に着脱可能に形成され、回転軸に交わるZ方向に移動するスライダ部に挟み込まれ、スライダ部の移動に伴い回転軸を中心にホルダ本体部36を回転させるアタッチメント部材38と、を備える。アタッチメント部材38は、ホルダ本体部36よりも摩擦係数が低い材質で形成される。【選択図】図6
