Abstract: An actuator includes a frame, a guide rail attached to the frame, a slider guided by the guide rail, a rotational motion-linear motion conversion mechanism that is disposed on a side opposite to the guide rail with the frame interposed therebetween and includes a screw shaft supported by the frame and a nut attached to the screw shaft, and a coupling member that couples the slider and the nut. The coupling member is coupled to the nut via a nut bracket. The coupling member is an annular member along an axial direction of the screw shaft, and includes a slider connection portion that has a plate shape and is fixed to the slider, and a nut bracket connection portion that has a plate shape and is fixed to the nut bracket.
