PROBLEM TO BE SOLVED: To provide a molding of bush being used for securing a lead wire and having high heat resistance causing no thermal deterioration, corrosion, cracking, or the like, even after long term use under pressure at high temperature in which excellent caulking properties compressible with a low load are exhibited without damaging the sealing performance, and a load required for compression can be selected appropriately. SOLUTION: The bush does not deteriorate thermally when it is placed under conditions of 25% compression rate conforming to JIS K 6262 at 300 deg.C for 1000 hours and/or does not crack when it is placed under conditions of 25% compression rate conforming to ASTMD 1414 (1994) clause 10 at 300 deg.C for 70 hours. |
