To provide a drive device that can suppress swinging of a movable member and contact noise between the movable member and a driven member in a configuration in which a movable member moves with translation of a driven member, and to provide a head-up display device.SOLUTION: A drive unit 30 includes a lead screw 34, a nut member 72, a slide member 42, a first arm part 78 and a second arm part 83. The nut member 72 receives turning force from the lead screw 34. The slide member 42 comes into contact with the nut member 72 to translate the nut member 72 and move in a translational direction of the nut member 72. The first arm part 78 and the second arm part 83 are formed in the nut member 72 and elastically deform with the contact between the nut member 72 and the slide member 42 in a turning direction of the lead screw 34.SELECTED DRAWING: Figure 5 【課題】従動部材の並進に伴って可動部材が移動する構成において、可動部材の揺動及び可動部材と従動部材との接触音を抑制することができる駆動装置及びヘッドアップディスプレイ装置を提供すること。【解決手段】駆動ユニット３０は、リードスクリュー３４と、ナット部材７２と、スライド部材４２と、第１アーム部７８及び第２アーム部８３とを有する。ナット部材７２は、リードスクリュー３４から回転力を受ける。スライド部材４２は、ナット部材７２との接触によって、ナット部材７２を並進させ且つナット部材７２の並進方向に移動される。第１アーム部７８及び第２アーム部８３は、ナット部材７２に形成され、リードスクリュー３４の回転方向におけるナット部材７２とスライド部材４２との接触に伴って弾性変形する。【選択図】図５
