摘要： A compact and simple linear actuator includes a spindle to a main body so as to be capable of moving in an axial direction, displacement detection device, a motor, and a transmission mechanism. The displacement detection device detects a movement displacement amount of the spindle. The motor is disposed adjacent a proximal end one of the spindle and on the same axis as the spindle. The transmission mechanism transmits turning force of the motor to the spindle. The transmission mechanism includes a first rotary member fitted to the proximal end of the spindle and integrally rotating with the spindle, a second rotary member fitted to a rotor of the motor, and connection rods for transmitting rotation of the second rotary member to the first rotary member. The connection rods have axes that are parallel to an axis of the spindle while being displaced from the spindle axis. The connection rods are rigidly connected to one of the first and second rotary members, and slidably received by the other of the first and second rotary members.
