To provide a flow channel switching device capable of switching a flow channel constitution in a fluid circuit with a compact constitution.SOLUTION: A flow channel switching device 1 for switching a flow channel constitution of a heat medium circuit 50 in which a heat medium is circulated, includes: a main body member 5; a plurality of connection members 20; and a drive portion 30. The main body member 5 is provided with a plurality of fluid flow channels 10. The fluid flow channel 10 has a connection port 15 to be connected to the fluid circuit, and a communication hole 13 opened so that the fluid passing through the connection port 15 can flow in and out. The plurality of connection members 20 are disposed on a surface of the main body member 5, and have connection flow channels 21 for connecting the communication hole 13 of the fluid flow channel 10 and the communication hole 13 of the other fluid flow channel 10. The drive portion 30 is disposed on the fluid flow channels 10, and drives a plurality of valve element portions 72 adjusting a flow rate of a fluid, at least in conjunction with each other. The drive portion 30 is disposed on the surface of the main body member 5.SELECTED DRAWING: Figure 4

    【課題】コンパクトな構成で、流体回路における流路構成を切り替えることができる流路切替装置を提供する。【解決手段】流路切替装置1は、熱媒体が循環する熱媒体回路50の流路構成を切り替える流路切替装置であって、本体部材5と、複数の接続部材20と、駆動部30と、を備えている。本体部材5には、複数の流体流路10が形成されている。流体流路10は、流体回路に接続する為の接続口15及び接続口15を通過した流体が流出入可能に開口された連通穴13を有している。複数の接続部材20は、本体部材5の表面に取り付けられ、流体流路10の連通穴13と、他の流体流路10の連通穴13とを接続する接続流路21を有する。駆動部30は、流体流路10に配置され、流体の流量を調整する複数の弁体部72を少なくとも連動して駆動させる。そして、駆動部30は、本体部材5の表面に配置されている。【選択図】図4
