Electronic control device

An electronic control device comprising:

• a circuit board to which, at one side thereof, a connector is fixed;
• a housing having a pair of connector sandwiching members that sandwich the connector in a thickness direction, a part of the connector being exposed to an outside of the housing and a remaining part of the connector and the circuit board being housed in a watertight space of an inside of the housing, and one of a pair of the connector sandwiching members being set to be higher in rigidity than the other;
• a seal portion formed at a fitting surface portion between periphery edges of a pair of the connector sandwiching members and at a fitting surface portion between an outer peripheral surface of the connector and an inner peripheral surface of the housing, the seal portion being filled with a sealant;
• and
• a shift suppression unit having fitting portions that are provided at the higher-rigidity connector sandwiching member and at the connector, the shift suppression unit suppressing a shift of the connector with respect to the housing by fitting of the fitting portions each other;
• wherein the fitting portions of the shift suppression unit is a protruding portion formed at one side of the higher-rigidity connector sandwiching member and the connector and a hollow portion formed at the other side;
• wherein the shift suppression unit functions as a guide part when fixing the connector to the housing by the fact that the protruding portion is fitted in the hollow portion with a predetermined gap provided between the protruding portion and the hollow portion;
• and
• wherein the predetermined gap between the protruding portion and the hollow portion is set to be smaller than a seal width of the seal portion filled with the sealant.
