A flow path switching valve in accordance with the present invention is a switching valve in which a first port, a second port and a third port are formed in a valve passage within a housing, and the second port and the third port are changed over so as to be communicated with the first port. A partition wall is formed between the second port and the third port, a valve axis is rotatably supported to a position near the partition wall. A valve body having valve wing portions in both sides and formed in an approximately L shape in a side view is mounted to the valve axis in such a manner as to change over the second port and the third port, and the valve wing portion in an open side is operated so as to close a gap between the valve wing portion and the partition wall at a time of changing over the valve. Accordingly, it is possible to close the gap between the valve axis and the partition wall at a time of changing over without using a complex seal structure, and it is possible to change over the valve while generating no leakage of the fluid or restricting the leakage. |
