Abstract

A relay-connecting member (16) has relay terminals (32), each of which is fit-connected to an output electrode (28) and a male tab (30) of an output terminal (14). With this structure, by simply inserting the output electrode (28) and the male tab (30) of the output terminal (14) into the relay-connecting member (16), it is possible to easily electrically connect the output electrode (28) and the male tab (30) of the output terminal (14) through the relay terminal (32).
