PROBLEM TO BE SOLVED: To provide a display position adjustment unit and a head-up display device which, while securing the ease of assembling a revolving shaft to a bearing, also reduces bearing play of the revolving shaft due to the bearing.SOLUTION: A revolving shaft 33 provided in a reflector 32 is formed with a maximum width W1 that is smaller than the minimum width Ws of a slit 341 in a bearing 34, and has a first bearing part 330 that slidingly contacts the bearing inner circumferential surface 340a of a bearing hole 340 in the bearing 34 on both radial sides on first diameter R1 assumed for the revolving shaft 33, and a second bearing part 331 that projects from an axial portion of the first shaft part 330 toward both radial sides on second diameter R2 assumed for the revolving shaft 33 perpendicular to the first diameter R1 and slidingly contacts the bearing inner circumferential surface 340a on both radial sides on the second diameter R2.SELECTED DRAWING: Figure 8

    【課題】軸受体に対する回転軸の組み付け容易性を確保するのと両立させて、軸受体による回転軸の軸受ガタを小さくする表示位置調整ユニット及びヘッドアップディスプレイ装置の提供。【解決手段】反射鏡32に設けられる回転軸33は、軸受体34におけるスリット341の最小幅Wsよりも小さな最大幅W1をもって形成されており、回転軸33に想定される第一径線R1上の径方向両側にて、軸受体34における軸受孔340の軸受内周面340aに摺接する第一軸部330と、第一径線R1に対して垂直に回転軸33に想定される第二径線R2上の径方向両側へ、第一軸部330における軸方向の一部から突出しており、当該第二径線R2上の径方向両側にて軸受内周面340aに摺接する第二軸部331とを、有する。【選択図】図8
