Provided is an actuator capable of shortening the overall length. An actuator (2) is provided with: a housing (7); a hollow shaft (8) rotatably supported by the housing (7) via bearings (9a, 9b) and having a bottom (8b); a screw shaft (14) connected to the bottom (8b) of the hollow shaft (8) and having a center line common to the hollow shaft (8); and a nut (15) which is in threaded engagement with the screw shaft (14). The nut (15) moves in the axial direction of the lead screw shaft (14) and can enter the space between the hollow shaft (8) and the lead screw shaft (14).
提供能够缩短全长的致动器。致动器(2)具备:外壳(7);中空轴(8),其经由轴承(9a、9b)而以能够旋转的方式支承于外壳(7),且具有底部(8b);丝杠轴(14),其与中空轴(8)的底部(8b)连结,且具有与中空轴(8)共同的中心线;螺母(15),其与丝杠轴(14)螺纹卡合。螺母(15)沿着丝杠轴(14)的轴向移动而能够进入中空轴(8)与丝杠轴(14)之间。
