CONSTITUTION:A holding rack is equipped with a pair of clamping frame 20 which nipping-hold both edge parts of a printed circuitboard 8 consisting of a soft thin plate and an adjusting shaft 11 for adjusting the interval W of the clamping frame 20. The clamping frame 20 is equipped with nipping holding frames 211-213, connecting member for connecting the nipping-holding frames 211-213, and a tightening shaft 25 for tightening the nipping-holding frames 211-213. The connecting member consists of a ring-shaped body having a slot, and the interval between the nipping-holding frames 211-213 is adjusted by engaging the engagement parts of the nipping-holding frames 211-213 in a slidable manner into the slot. It is suitable to install an elastic member which can hardly slide, in the holding part of the thin plate. |
