<p>PROBLEM TO BE SOLVED: To prevent cracking and breaking of a resin part making contact with a non-magnetic substrate, etc., and to improve press fitting force by providing a ferromagnetic plate on a back surface of the non-magnetic substrate and functionally separating a magnet part applying press fitting force to a portion making contact with a surface of the non-magnetic substrate. SOLUTION: A substrate press fitting jig 1 is constituted of a ferromagnetic plate 5 arranged on a main surface of a non-magnetic substrate 2, a magnet 3 buried in the non-magnetic substrate 2, a spring 6 and a spring body a head end of which is constituted of a spherical resin member 4 and projected on the other main surface of the substrate 2, and the head end of the resin member 1 makes contact with a glass substrate, etc. The magnet 3 is buried at a position where a magnetic line of force comes to be in a roughly vertical direction against the ferromagnetic plate 5 to improve press fitting force of the substrate press fitting jig 1. A non-magnetic thin plate 7 is on the side of the glass substrate of the magnet 3 for prevention of direct contact of the magnet 3 to the glass substrate, etc., and falling of magnet powder due to production of cracks of the magnet 3, etc., and improvement of press fitting force.</p> |
