Abstract

PROBLEM TO BE SOLVED: To exchange electrical components to be mounted to a printed wiring board, without breaking a power supply being supplied to a device rack by flexibly supporting first and second support parts located at both sides at the center of a gripping member at the first and second support parts of a component-mounting plate. SOLUTION: When a component-mounting plate 29 is pulled out of a printed wiring board 23, a gripping member 39 allows a large-diameter part 39e to project and to be curved toward the opposite side of the component-mounting plate 29 with first and second support components 39a and 39b as supports by pinching the large-diameter part 39e of the gripping member 39, and pulling the part to the opposite side of the part-mounting plate 29. When an apparent length L of the gripping member 39 becomes equal to the interval of first and second guide rails 25 and 27 due to the curve, gear-lock projections 39c and 39c are disengaged from gear-lock holes 25d and 27d of the first and second guide rails 25 and 27 and slide on first and second guide rails 25 and 27, and then the component-mounting plate 29 is pulled out of the first and second guide rails 25 and 27.
