## Abstract

The present invention relates to an electronic control device which is an electronic control device such as an engine ECU for a vehicle and has a tight sealing structure between a case and a connector. The present invention provides an electronic control device for a vehicle, which implements a new type of sealing manner in which a space to be filled with a sealing material is formed between a case side dam and a connector side dam when a case and a connector of the electronic control device are assembled, and the sealing material is applied in the space, which is formed as described above, such that airtightness for an assembly region between the case and the connector is maintained, thereby securing sufficient sealing areas because of enlarged sealing sections, and achieving stable sealing quality and improving quality.

## Claims

### Claim 1

An electronic control device for a vehicle, which has an electronic control element that electrically controls each part of a vehicle, comprising:
a cover 10 and a base 11 which accommodate the electronic control element; and
a connector 12 which is coupled to front surfaces of the cover 10 and the base 11,
wherein protrusions 13a and 13b are formed along an outer periphery of a rear end portion of the connector 12 and inner peripheries of front end portions of the cover 10 and the base 11 which come into contact with the outer periphery, the protrusions 13a and 13b maintain predetermined gap, and a sealing member 14 is applied in the gap such that sealing is made at portions where surfaces of the cover and the base meet surfaces of the connector.

### Claim 2 (depends on 1)

The electronic control device of claim 1, wherein the protrusion 13a of the connector 12 is formed as an inclined surface 15 which faces the protrusion 13b of the cover 10

### Claim 3 (depends on 1, 2)

The electronic control device of claim 1 or 2, wherein the protrusions 13b of the cover 10 and the base 11 is formed as curved surfaces 16 which face the protrusion 13a of the connector 12.

### Claim 4 (depends on 1, 2)

The electronic control device of claim 1 or 2, wherein at least one surface of the connector and the base, which face each other into the gap that are formed between the protrusion 13a of the connector 12 and the protrusions 13b of the cover 10 and the base 11, is formed as a recessed portion 17.

### Claim 5 (depends on 1, 2)

The electronic control device of claim 1 or 2, wherein sealing between the cover 10 and the base 11 is made by using a groove 18a and a projection 18b, which are formed along edges where the cover 10 and the base 11 come into contact with each other, and by the sealing member 14 that is applied in the groove 18a and the projection 18b.
