PROBLEM TO BE SOLVED: To provide a selector valve which can switch with small force and which has high seal performance and durability.SOLUTION: By moving a valve body in a valve chamber, a flow passage opened to an inner wall surface of the valve chamber is opened/closed. When the valve body is in a position for closing the flow passage, a valve body energization part energizes the valve body and presses it against the inner wall surface. However, when the valve body is moved to the position for not closing the flow passage, a contact part comes into contact with the valve body and presses and shrinks the valve body energization part, so that the valve body comes into a state of being separated from the inner wall surface. Therefore, the valve body and the inner wall surface do not slide with each other, so that the valve body can be moved with small force. As a result, switching can be performed with small force, and also, as the valve body and the inner wall surface do not slide with each other, the risk of deterioration of seal performance due to a foreign object and the like and deterioration of durability can be suppressed. |
