PURPOSE:To improve the yield of a gap for prevention against flame propagation by cutting an end surface of a cylindrical cover positioned at the binding force part side of a load cell body to length shorter than the binding force part end surface of the main body by the width of the necessary gap, and fixing a counter member to the binding force part of end surface of the main body. CONSTITUTION:The cover 18 is fixed to the load cell body 10 with a bolt 19, and the binding force point side end part 29 of the cover 18 and the binding force point side end part 30 of the main body 10 are cut to the same level. Then, only the end surface 29 is cut to length which is size W shorter. Then, the discoid counter member 31 which faces the end surface 29 to length L is fixed to the end surface 30 with a bolt 32 to form the gap which has width W and depth L. Thus, the gap for prevention against flame propagation which the depth L and width W is formed between the cover 18 and counter member 31 at high yield. |
