A parallel type integrated actuator is proposed. The actuator includes: a driving unit composed of a first motor, a second motor, a third motor, and a fourth motor; a first shaft, a second shaft, and a third shaft, each shaft being inserted into each other through a hollow structure and forming a co-axis, each shaft being capable of rotating relative to each other in an inserted state, and each shaft having the other end part thereof extending outside the driving unit; an distal end part disposed outside the driving unit and on which an actuator is mounted; a first link part, a second link part, and a third link part allowing the distal end part to rotate in pitching, yawing, and rolling directions; and a universal link part connecting the fourth rotor, which is a rotor of the fourth motor, and the distal end part to each other.
