Cable coupling mechanism

A cable linking mechanism, comprising:

• a connection target to which a cable is connected;
• and
• a case with internal space slidably accommodating the connection target, wherein:
• the case comprises:
• a case body with a sliding surface on which the connection target slides;
• a lid member capable of closing the case body;
• and
• a hinge that connects the case body and the lid member,
• the case body and the lid member are configured to allow relative rotation with respect to each other about the hinge between an open position where the internal space of the case is open and a closed position where the case body is closed with the lid member,
• one of the case body and the lid member comprises an outer wall portion that protrudes and extends outward from the one of the case body and the lid member to another one of the case body and the lid member when the case body and the lid member are in the closed position,
• the another one of the case body and the lid member comprises an inner wall portion inside in a direction opposite to a direction to the one of the case body and the lid member when the case body and the lid member are in the closed position, the inner wall portion being capable of making contact with the outer wall portion,
• the outer wall portion is placed outside from the inner wall portion in a radial direction of the relative rotation, and
• the outer wall portion and the inner wall portion are placed to restrict, by making contact with each other, a relative movement of the lid member with respect to the case body along the sliding surface in a direction away from a rotation axis of the relative rotation when the case body and the lid member are in the closed position and a load is applied to the case body and/or the lid member so that the lid member performs the relative movement.
