FITTING STRUCTURE OF ON-VEHICLE ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a fitting structure for fitting a casing 2 housing an electronic device to a body 12, capable of reducing impedance between the casing and the body not bound by the shape of the casing or the like.SOLUTION: The proximate place of a casing 2 and a body 12 is surrounded with a surrounding wall 6, and a space surrounded with the surrounding wall is filled a particle group 10. The particle group having a conductive surface is used. Each particle is compressed more than a natural shape, and pressurized to fill until a state where a returning force to the natural state is applied. The particle group 10 pressurized to fill adheres to both the casing 2 and the body 12 to reduce impedance between the casing 2 and the body 12. This fitting structure is not bound by the shape of the casing 2 or the like.
