ELECTRICAL DISCHARGE DEVICE

WIPO Patent Application WO/2023/162585

A1

The present invention provides an electrical discharge device in which a mounting retention means for retaining an electrical discharge unit in a mounted state is capable of exhibiting the functionality thereof in a stable manner for an extended period of time, and which does not require high precision for the mounting retention means, thereby allowing manufacturing with good yield. The mounting retention means is formed using a first magnetic body 53 provided to an electrical discharge unit 16, and a second magnetic body 54 which is provided to a base section 15 and can be magnetically attached to the first magnetic body 53. The attachment force acting between the magnetic bodies 53, 54 does not degrade due to repeated attachment and detachment of the electrical discharge unit 16, is relatively unaffected by variations in dimensions, etc., of the magnetic bodies 53, 54, and has a substantially constant magnitude. Therefore, the electrical discharge unit 16 can be retained in a mounted state at an appropriate attachment force even if there is a slight amount of variation in the dimensions, etc., of the magnetic bodies 53, 54.
