The inner unit of a gyroscope is of circular shape and is formed with an inclined outer edge at one end. The inner unit slides within an outer casing having a transverse end face at one end. An annular recess of triangular section is thereby defined between the inner unit and casing which receives a ring of resilient material. During assembly the inner unit is urged against the end of the casing, to compress the ring within the recess, by reducing pressure within the casing. The inner unit is held in position, with the ring compressed, by soldering an end plate to the casing. The pressure within the casing can then be returned to normal.
