To provide a flow path switching valve capable of switching between many modes with a simple configuration.SOLUTION: A flow path switching valve 101 comprises a pair of valve bodies 120 provided rotatably about a rotation center and having at least one valve inner path (one side path 121 and the other side path 122) defined in the inside, and a housing 110 accommodating the pair of valve bodies 120. The housing 110 has: a pair of valve body accommodation sections 111 in which the valve bodies 120 are rotatably disposed; a plurality of connection holes 112 which provide communication between the valve body accommodation sections 111 and the outside of the housing 110, and which communicate with the valve inner path (one side path 121 and the other side path 122) in either of the pair of valve bodies 120; and a communication hole 113 providing communication between the respective valve body accommodation sections (111).SELECTED DRAWING: Figure 12 【課題】簡素な構成で多くのモードの切り換えが可能な流路切換弁を提供する。【解決手段】流路切換弁１０１は、回転中心まわりに回転可能に一対設けられ、少なくとも一つの弁内通路（一方側通路１２１及び他方側通路１２２）が内部に画成される弁体１２０と、一対の弁体１２０を収容するハウジング１１０と、を備え、ハウジング１１０は、弁体１２０が回転可能に配置される一対の弁体収容部１１１と、弁体収容部１１１とハウジング１１０の外部とを連通させ、一対の弁体１２０のいずれかにおける弁内通路（一方側通路１２１及び他方側通路１２２）と連通する複数の接続孔１１２と、各々の弁体収容部１１１の間を連通させる連通孔１１３と、を有する。【選択図】図１２
