A leg is coupled to one half of the connecting structure, e.g. a detachable seat, via screw engagement and the latter is coupled, via wedge engagement to be established by projections formed thereon, to the other half of the connecting structure, e.g. a fixed seat, mounted to the bottom of a massive body such as a keyboard musical instrument, a larger sized television set and a heavy table. Registration of the leg at the correct position and the above-described wedge engagement are carried out simply by sliding the one seat against the other seat with alleviated trouble in the collimation work, reduced damage on the thread construction and stabilized support for the massive body. |
