Connector removal-restricting structure

A connector removal-restricting structure comprising:

• an electronic control unit including a unit-side connector;
• an external connection connector including
• an external connector body connected to the unit-side connector and
• a locking member supported by the external connector body in a manner movable between a locked position closer to the external connector body and an unlocked position on one side in a first direction with respect to the locked position,
• wherein the locking member is configured that a movement in a detachment direction of the external connector body in a connector connected state, in which the external connector body is connected to the unit-side connector, is restricted in a locked state in which the locking member is located at the locked position, and a movement in the detachment direction of the external connector body in the connector connected state is allowed in an unlocked state in which the locking member is located at the unlocked position;
• and
• a sealing member configured to be attached to the external connection connector and the electronic control unit in the locked state by sliding from the one side to the other side in the first direction while being restricted from moving in a direction intersecting the first direction, and to, at a sealed position on the other side, restrict movement of the locking member with respect to the external connector body from the locked position toward the unlocked position,
• wherein at least one of the electronic control unit or the external connector body includes a first engaging portion, and
• wherein the sealing member includes:
• a contact portion configured to, at the sealed position, contact the locking member in the locked position from the one side in the first direction;
• and
• a second engaging portion configured to, at the sealed position, be engaged with the first engaging portion to restrict movement of the sealing member toward the one side in the first direction with respect to the electronic control unit and the external connection connector in the locked state.
