Abstract
(EN)
The present invention provides a driving device that can be inhibited from being damaged. A base member (4) includes a frame section (41) that rotatably supports a movable part via shaft parts provided on the inner circumferential side thereof, and elastic structural sections (42) extending toward the outer circumferential side of the frame section. As a result of the elastic structural sections (42) of the base member (4) being joined to a base (7), the difference in the amount of thermal deformation between the base member (4) and the base (7) can be absorbed by deformation of the elastic structural sections (42), and thus, damage to the driving device can be inhibited.
(FR)
La présente invention concerne un dispositif d'entraînement pouvant être protégé contre un endommagement. Un élément de base (4) comprend une section de cadre (41) qui supporte de manière rotative une partie mobile par l'intermédiaire de parties d'axes disposées sur son côté circonférentiel interne, et des sections structurales élastiques (42) s'étendant vers le côté circonférentiel externe de la section de cadre. Consécutivement au fait que les sections structurales élastiques (42) de l'élément de base (4) sont reliées à une base (7), la différence de la quantité de déformation thermique entre l'élément de base (4) et la base (7) peut être absorbée par une déformation des sections structurales élastiques (42), ce qui permet d'empêcher un endommagement du dispositif d'entraînement.
(JA)
破損を抑制することができる駆動装置を提供する。ベース部材(4)が、内周側に設けられた軸部によって可動部を回動可能に支持する枠状部(41)と、枠状部の外周側に延びる弾性構造部(42)と、を有する。ベース部材(4)の弾性構造部(42)が台座(7)に対して接合されることで、ベース部材(4)と台座(7)とに生じた熱変形量の差を、弾性構造部(42)の変形によって吸収させることができ、駆動装置の破損を抑制することができる。
