PROBLEM TO BE SOLVED: To provide a display position adjustment unit that exhibits quietness and the stability of a virtual image display position.SOLUTION: A bearing body 34 locks a first shaft part, projecting in a specific X direction, of a rotary shaft 33 in a specific X direction. A drive source has an output shaft connected with the first shaft part. The bearing body 34 bears a second shaft part 332, projecting in an opposite X direction, of the rotary shaft 33 by means of a recess part 343 receding in a specific Z direction. A reflector 32 has a projection part 322 projecting in the opposite X direction from the outer periphery side of the second shaft part 332. A main elastic member 35 has: an attachment part 350 attached to the bearing body 34; and a slide part 351 that slides on the projection part 322 and, thereby, the inclining restoring force of a line of action in the opposite X direction and the opposite Z direction is caused to act on the projection part 322.SELECTED DRAWING: Figure 9
【課題】静粛性及び虚像表示位置の安定性を発揮する表示位置調整ユニットの提供。【解決手段】軸受体34は、回転軸33のうち特定X方向に突出している第一軸部を、特定X方向に係止する。駆動源は、第一軸部と連繋している出力軸を、有する。軸受体34は、回転軸33のうち逆X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343により軸受している。反射鏡32は、第二軸部332の外周側を逆X方向に突出している突部322を、有する。主弾性部材35は、軸受体34に装着されている装着部350と、突部322に摺動することにより、逆X方向と逆Z方向とに対して作用線Lfの傾斜する復原力を、突部322に作用させる摺動部351とを、有する。【選択図】図9
