界を超えないように設定されている。 Further, the distance D between the support leg 4 and the regulating piece 6 is larger than the bending range (movement distance) of the support leg 4 necessary for attaching and detaching the printed circuit board 2, that is, the width d of the engaging claw 3. It is set so that the elastic limit for bending of the support leg 4 is not exceeded.
さらに、支持脚４の肉厚は折曲げ方向に直交す
