To provide a thermal valve unit that is readily assembled, and to provide a heat source machine including the same and a method for manufacturing a thermal valve unit that allows for simple assembling.SOLUTION: A thermal valve unit 50 includes: a first housing H1; a second housing H2; a first seal member S1; a second seal member S2; a first thermal valve part V1; and a second thermal valve part V2. The first seal member S1 is positioned while being relatively offsite to a position of the second seal member S2 relative to a main flow passage FP in a second direction D2 orthogonal to a first direction D1.SELECTED DRAWING: Figure 3 【課題】組立てが容易となる熱動弁ユニットおよびそれを備えた熱源機ならびに組立てが容易となる熱動弁ユニットの製造方法を提供する。【解決手段】熱動弁ユニット５０は、第１筐体Ｈ１と、第２筐体Ｈ２と、第１シール部材Ｓ１と、第２シール部材Ｓ２と、第１熱動弁部Ｖ１と、第２熱動弁部Ｖ２とを備えている。第１方向Ｄ１に直交する第２方向Ｄ２において、第１シール部材Ｓ１の位置は、主流路ＦＰに対して第２シール部材Ｓ２の位置と相対的にずれている。【選択図】図３
