Abstract
A connector includes: a connector body formed in a tubular shape; and a valve body stored inside the connector body, the valve body being configured to, when high-pressure fuel does not flow back, come into a first state in which a forward flow path is formed between the valve body and an inner circumferential surface of the connector body by a pressure of low-pressure fuel, and when high-pressure fuel flows back, come into a second state in which an orifice flow path having a smaller flow path sectional area than the forward flow path is formed between the valve body and the inner circumferential surface of the connector body.
