Abstract

PROBLEM TO BE SOLVED: To facilitate the terminal connecting operations and enhance the yield by furnishing the housing with a provisionally attaching part for terminal, and fixing the terminal to the connecting part in the condition that it is attached provisionally. SOLUTION: A provisionally attaching part 26 for terminal as a groove having a U-section is formed at that side face of a housing 20 where a terminal connecting part 14 is protruding, and one end of a terminal 28 in the form of round rod is connected with that part of terminal connecting part 14 adjacent to the part 26. The base end of the terminal 28 is spot welded to the terminal connecting part 14, and thus the connection and fixation are established. According to this configuration, the terminal connecting operations are facilitated, and good yield can be expected.
