Precision substrate storage container and retaining member therefor

摘要

A presser member ( 1 ) of the present invention is formed of different materials for the contacting part ( 5 ) to press-hold the precision substrates ( 15 ) and for the parts other than the contacting part ( 5 ). The presser member ( 1 ) is shaped from a thermoplastic elastomer for a rectangular frame part, and the contacting part ( 5 ) has a pair of structuring parts ( 4 ) provided in such a fashion as to inwardly extend from each of a pair of oppositely facing sides. A second contacting part ( 11 ) is formed in the extension peripheral part extending via a supporting part ( 10 ). The other parts are shaped from a thermoplastic resin. The aforementioned contacting part ( 5 ) is provided with grooves of a V-shaped cross section with inclinations changed in the middle for receiving the peripheries of precision substrates ( 15 ), and V-grooves for press-holding the peripheries of precision substrates are provided in resilient pieces ( 12 ) separated and protruding in a comb teeth-like fashion to form the second contacting part ( 11 ).
