ABSTRACT:
An erector for holding a spin axis of a gyro rotor in the vertical direction used in a gyroscopic horizon or gyro vertical which comprises a gyro casing incorporating therein a gyro rotor rotating at high speed, a spin axis of the gyro rotor being held substantially in the vertical direction, first supporting member for rotatably supporting the gryo casing around a first horizontal axis which is perpendicular to the spin axis and second supporting member for rotatably supporting the first supporting member around a second horizontal axis which is perpendicular to both the spin axis and the first horizontal axis is disclosed, which includes a base plate, a motor mounted on the base plate, a rotation receptacle container having an annular shape cavity and rotated at low speed by the motor, and liquid charged into the annular shape cavity of the rotation receptacle container, the base plate being mounted on the gyro casing such that the rotation axis of the rotation receptacle container and the spin axis of the gyro rotor become parallel to each other.
