PURPOSE:To improve the yield of a gap for prevention against flame propagation by cutting the binding force side end surface of a load cell body and the binding force side end surface of a cover to the same level, and fixing a counter member to the binding force end surface of the load cell body with a spacer plate between. CONSTITUTION:The cover 18 is fixed to the load cell body 10 with a bolt 19 and the binding force side end surface 29 of the cover 18 and the binding force point side end surface 30 of the main body 10 are cut to the same level. Then, the discoid counter member 31 which faces the end surface to more than length L is fixed to the end surface 30 with a bolt 33 while the spacer plate 32 with uniform thickness (t) is interposed to form the gap alpha which has width W and depth L. Thus, the gap alpha for flame propagation prevention which has the depth L and width W is formed between the cover 18 and counter member 31 at high yield. |
