<p>PROBLEM TO BE SOLVED: To easily fit the lock tool not from below to right above, but slantingly upward by forming a slanting surface part for making a fixation member for fixing the lock tool to the reverse surface of a shelf part enter the shelf part slantingly. SOLUTION: The top surface of the lock tool 1 is an upper abutting part 2 (1st abutting part) which is flat and abuts against the reverse surface of a shelf plate 21 (shelf part). The corner part at the inner lower edge of the lock tool 1 is cut in an 'L' shape to form a step abutting part 3 (2nd abutting part). The 'L'-shaped recessed part of this step abutting part 3 is a nearly right-angled corner recessed part and the front upper edge corner part of a front plate 22 engages and abuts against it. In the center of its slanting surface part 5, a through hole 6 is formed almost at right angles to the slanting surface part 5. A wooden screw 7 is screwed in the through hole 6 and then screwed slantingly in the shelf plate 21 from its reverse surface by projecting from the upper abutting part 2.</p> |
