Abstract

PURPOSE: To prevent a metal fitting from easily falling off regardless of the dimensional tolerance of a wedge base bulb. CONSTITUTION: A locking end part 34c outwardly bent almost perpendicularly to the opening direction of a cylinder part is formed in the tip part of a movable contact piece 34 of an abutting metal fitting and at the same time, the locking end part 34c is made so as to abut on the locking wall surface 23a1 of the lower surface of a locking wall 23a formed outside a cylinder part 21 from the down side. For that reason, when a wedge base bar 10 is pulled out, the movable contact piece 34 becomes about to fall off upwards and however, the locking end part 34c abuts on the lower surface of the locking wall surface 23a1 to match against the pull-out force, thereby preventing the abutting metal fitting 34 from falling off.
