ABSTRACT:
A test rack for electronic equipment features an improved mechanism for inclining the test rack table in a smooth and effortless manner even when heavily loaded with equipment. Notches provided on a stopper plate are allowed to mate with a stopper shaft by sliding the stopper plate along a guide portion when the table is set at a desired angle of inclination. The stopper plate is constrained to slide at substantially right angles to the stopper shaft at all times so that the stopper shafts engages squarely with the notches to preclude jamming when the mechanism is operated under a heavy load.
