CONNECTOR

Provided is a connector that is capable of preventing breakage or dislocation of an actuator when an excessive force is applied to the actuator in an opening direction of the actuator, and also enables easy and reliable closing of the actuator during assembly of the actuator by an automatic assembling machine. An actuator (40) includes a pair of arms (40B) that are arranged on either side of an accommodation section (20A) and extending from either end of a pressing portion (40A) in an insertion direction of a connection object (12). The pair of arms (40B) and an insulator (20) include first open state restriction unit (40F, 23E) configured to restrict an opening angle of the actuator (40) from a closed state to an opened state.
