<p><P>PROBLEM TO BE SOLVED: To solve a problem with a conventional electronic control device that when the pressure jet caused by the high-pressure washing strikes a breathing filter, a very small space is formed between an O-ring of the breathing filter and a contact surface of a cover, and water possibly enters inside a case. <P>SOLUTION: In order to protect a breathing filter from pressure jet of the high-pressure washing, the breathing filter is supported by two kinds of projections of different heights so as not to be moved even when the pressure jet directly strikes the breathing filter during the high-pressure washing, preventing any very small space from being formed between an O-ring of the breathing filter and a contact surface of a cover, and preventing water ingress inside a case. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
