Abstract
A circuit board supporting electronic components mounted thereon is housed in a casing. The casing has a joint hole defined therein, and a connector is inserted in the joint hole with a water-resistant seal placed in a gap between the connector and edges of the casing which define the joint hole. The casing is of a trapezoidal shape and has a pair of parallel sides spaced from each other by a distance, the parallel sides having respective lengths greater than the distance between the parallel sides. The casing has a tooth as a stop which has a tip end held against the connector at a position in which the casing and the connector closely confront each other in or near a region of at least one of the parallel sides which is sealed by the water-resistant seal.

An electronic control device comprising:
- a circuit board supporting electronic components mounted thereon;
- a casing housing said circuit board therein;
- said casing having a joint hole defined therein and having a quadrangular shape, said joint hole having a pair of parallel sides spaced from each other by a distance, said parallel sides having respective lengths greater than said distance between the parallel sides;
- and
- a connector inserted in said joint hole with a water-resistant seal placed in a gap between said connector and edges of said casing which define said joint hole;
- one of said casing and said connector having a tooth as a stop, said tooth having a tip end held against the other of said casing and said connector, at a position in which said casing and said connector closely confront each other in or near a region of at least one of said parallel sides which is sealed by said water-resistant seal.
