Abstract
(EN)
Provided are a drive device that minimizes rattling of a movable member in a movement direction, and a drive device used in a head-up display device. Specifically, a drive device 1 has a drive unit 3, a lead screw 4 rotatably driven by the drive unit 3, and a movable member 6 moved by driving force of the drive unit 3. The movable member 6 is provided with a main body unit 9, a driving force transmission unit 41 that transmits the driving force of the drive unit 3 to the main body unit 9, and preloading units 42, 43 provided separately from the main body unit 9. The driving force transmission unit 41 is provided with a first screw part threaded into the lead screw 4, and the driving force transmission unit 41 causes the main body unit 9 to move in an axial direction L of the lead screw 4 together with the rotation of the lead screw 4. The preloading units 42, 43 are provided with a second screw part threaded in the lead screw 4, and the preloading units 42, 43 impart a preload between the first screw part and the second screw part.

L'invention concerne un dispositif d'entraînement qui réduit au minimum le cliquetis d'un élément mobile dans une direction de mouvement, et un dispositif d'entraînement utilisé dans un dispositif d'affichage tête haute. Plus précisément, un dispositif d'entraînement (1) comprend une unité d'entraînement (3), une tige filetée (4) entraînée en rotation par l'unité d'entraînement (3), et un élément mobile (6) déplacé par la force d'entraînement de l'unité d'entraînement (3). L'élément mobile (6) est pourvu d'une unité corps principal (9), d'une unité de transmission de force d'entraînement (41) qui transmet la force d'entraînement de l'unité d'entraînement (3) à l'unité corps principal (9), et des unités de préchargement (42, 43) disposées séparément de l'unité corps principal (9). L'unité de transmission de force d'entraînement (41) est pourvue d'une première partie de vis filetée dans la tige filetée (4), et l'unité de transmission de force d'entraînement (41) amène l'unité corps principal (9) à se déplacer dans une direction axiale (L) de la tige filetée (4) conjointement avec la rotation de la tige filetée (4). Les unités de préchargement (42, 43) sont pourvues d'une seconde partie de vis filetée dans la tige filetée (4), et les unités de préchargement (42, 43) appliquent une précharge entre la première partie de vis et la seconde partie de vis.
