The ECU as described above is widely applied to engine control in particular, and executes appropriate control according to the state of the vehicle and the engine mainly by fuel injection amount control and ignition timing control.

In addition, the ECU is not separately provided inside the engine compartment, but is provided through another bracket.

That is, although the conventional technique is provided inside the engine compartment after the ECU 10 and the bracket 20 are bolted at two locations as shown in fig. 1 and 2, there is a problem that noise caused by swimming causes customer complaints.

In order to solve such a problem, the bracket 20 is recently formed of plastic and used, but has problems of aging, temperature variation according to seasons, and abrasion due to vibration.

Specifically, the case where the holder 20 is formed of plastic has the following problems.

First, the material characteristics of plastic have a problem that noise is generated due to the occurrence of play caused by vibration of a vehicle in the conventional structure, which is inevitable due to wear resistance.

Secondly, the material characteristics of the plastic have the problem that the size changes during assembly, and the gap generates noise along with the increase of the use environment (temperature and humidity) and vibration.
