[Scope of utility model registration request]

It consists of an upper side bent into an inverted L shape and a leg, a notch is provided on the side of the upper side, an engaging protrusion and an engaging claw are provided on the plane of the leg, and the side of the leg is provided with an engaging protrusion and an engaging claw. A connection terminal board having an engagement protrusion protruding from this, a surge absorption element mounted thereon, an engagement hole into which the engagement protrusion of the connection terminal board fits, and a solder into which the engagement claw is engaged. A printed circuit board having a through-hole for use in the case is assembled by fitting the engaging protrusion into the engaging hole and engaging the engaging claw and the through-hole to form an assembled structure, which surrounds the opening of the case. The notch of the connection terminal plate is engaged with a case protrusion provided on the upper part of the wall, and the engagement protrusion of the connection terminal plate and one side of the printed circuit board are fitted into grooves formed on both inner wall surfaces of the case. An assembly structure for a surge absorption unit, characterized in that the assembled structure is fixed to a case by inserting a.
