Summary:PURPOSE:To make a terminal plate attachment working to a hooking groove formed in a supporting pole which receives an electric application spring. CONSTITUTION:A hooking groove 5a is formed in a supporting pole 5 projected in a cover 1 having a surrounding wall 1a. The hooking groove 5a is so set as to make the distance from the terminal metal fitting of the cover 1 to its opposite plane shorter than the distance from the tip of the surrounding wall 1a. A cut out groove 4a formed in a terminal plate 4 is joined with the hooking groove 5a and an electric application spring 2 attached to the supporting pole 5 is brought into contact with the terminal plate 4. The terminal plate 4 is inserted into the supporting pole 5 from the surrounding wall 1a side and a cut out part 5b is so formed in the terminal plate 4 insertion side of the supporting pole 5 as to make the distance from the surrounding wall 1a wide at the part between the hooking groove 5a and the tip end of the supporting pole 5.
