PROBLEM TO BE SOLVED: To prevent unreasonable stress from being applied to each member upon assembling even when variations of the sizes of nipple and the like are greater. SOLUTION: An elongated hole shaped connection tube takeout hole 24 is provided in a top plate 2 of a case 20 through which a combustor side connection tube 45 is inserted. An eyelet 50 is filled in the connection tube takeout hole 24 such that it is movable longitudinally of the connection tube takeout hole 24. An insertion hole 51 is provided in the center of the eyelet 50 to which tube 45 the combustor side connection tube 45 is brought into close contact for its insertion into the insertion hole 51. As a result, even when a gas adjuster 30 disposed in the case 20 is displaced owing to variations of the size of a nipple 41, the combustor side connection tube 45 is moved corresponding to the variations together with the eyelet 50 to prevent greater force from being applied to each member.
