Abstract
A seal ring is made of resin, applied to a valve body that changes an opening degree of a fluid passage through which a fluid passes, and that seals, when the valve body fully closes the fluid passage, between an inner peripheral surface defining the fluid passage and an outer peripheral edge of the valve body. The seal ring includes a ring main body fitted in an outer peripheral groove formed on the outer peripheral edge.
