To provide an actuator that can easily and reliably perform control for slidably driving an output shaft in a first direction and control for rotationally driving the output shaft.
The actuator 1 includes the output shaft 12 that is supported in a case 11 so that it can be linearly and slidably moved in the first direction A and can be rotated on the shaft center B orthogonal to the first direction A. It can slidably drive the output shaft 12 in the first direction A and can rotationally drive the output shaft. The actuator 1 includes: a first motor 14 that is fixed in the case 11 and drivably coupled to the output shaft 12 and drives the output shaft 12 in the first direction A; and a second motor 15 that is drivably coupled to the output shaft 12 through a slide permitting coupling mechanism that permits the slidable movement of the output shaft 12 in the first direction A and rotationally drives the output shaft 12.
