摘要：
A seal ring of a valve element includes a one-end joint forming portion and an other-end joint forming portion. The one-end joint forming portion includes a one-end first contact portion and a one-end second contact portion located on one side of the one-end first contact portion in an axial direction and extending in a circumferential direction beyond the one-end first contact portion. The other-end joint forming portion includes an other-end first contact portion and an other-end second contact portion located on the other side of the other-end first contact portion in the axial direction and extending in the circumferential direction beyond the other-end first contact portion. An inner diameter of the seal ring when the one-end first contact portion separates from the other-end second contact portion is less than an outer diameter of the valve element.
