Summary:PROBLEM TO BE SOLVED: To provide an air supply cylinder for relay capable of maintaining performance even in an installation condition that air supply resistance is large.SOLUTION: An air supply cylinder for a relay in this invention is an air supply cylinder 12 for relay that is connected between a body side air supply cylinder 11 connected to an air blower for combustion included in the body of heating equipment 3, and an air supply cylinder 13 for extension taking in combustion air from outside. The air supply cylinder 12 for relay has: a large diameter part R2 whose inner diameter is larger than that of the air supply cylinder 13 for extension; and a small diameter part R3, whose inner diameter is smaller than the diameter of the air supply cylinder 13 for extension, closer to the side of the air supply cylinder 13 for extension than the large diameter part R2.SELECTED DRAWING: Figure 2 【課題】給気抵抗が大きい設置条件においても性能を維持することができる中継用給気筒を提供する。【解決手段】 暖房機器3本体に備えられた燃焼用送風機に接続される本体側給気筒11と、屋外から燃焼用空気を取り入れる延長用給気筒13との間に接続される中継用給気筒12である。中継用給気筒12は、内径が延長用給気筒13より大径となるように構成された大径部R2と、大径部R2より延長用給気筒側13に、内径が延長側用給気筒13より小径な小径部R3を有する。【選択図】 図2
