Abstract
The present invention provides a new arrangement of the stem and the cap resistance-welded to the stem, in which the deformation induced by the welding in a portion adjacent to the projection does not cause the failure for the assembly of the module. The cap and the stem of the present module provided first and second portions. The diameter of the second portion is greater than that of the first portion such that, even the welding deforms the first portions of the cap and the stem; the deformed portion is inside of respective second portions.
